title: Measurements of |V_{cb}| and |V_{ub}| at BABAR

abstract:
  We report on new measurements of the Cabibbo-Kobayashi-Maskawa matrix
elements |V_{cb}| and |V_{ub}| with inclusive and exclusive semileptonic B
decays, highlighting the recent precision measurements with the BABAR detector
at the PEP-II asymmetric-energy B Factory at SLAC.


title: Quantum Chromodynamics at Colliders

abstract:
  QCD is the accepted (that is, the effective) theory of the strong
interaction; studies at colliders are no longer designed to establish this.
Such studies can now be divided into two categories. The first involves the
identification of observables which can be both measured and predicted at the
level of a few percent. Such studies parallel those of the electroweak sector
over the past fifteen years, and deviations from expectations would be a sign
of new physics. These observables provide a firm ``place to stand'' from which
to extend our understanding. This links to the second category of study, where
one deliberately moves to regions in which the usual theoretical tools fail;
here new approximations in QCD are developed to increase our portfolio of
understood processes, and hence our sensitivity to new physics. Recent progress
in both these aspects of QCD at colliders is discussed.


title:
Measurement of $\Delta S$ in the nucleon at HERMES from semi-inclusive
  DIS

abstract:
  The helicity distribution of the strange quark sea in the proton has been
extracted from measurements of polarized production of charged kaons in
deep-inelastic scattering from a polarized deuterium target.


title:
Search for Rare and Forbidden Decays of D mesons to Final States with
  Electrons

abstract:
  Using the CLEO-c detector and a data sample of 0.8 million D+D- pairs at the
Psi(3770) a search has been performed for flavor changing neutral current and
lepton number violating decays of D+ mesons to final states with dielectrons.
No signals are observed and 90% confidence limits are set for specific decay
modes in the range of a few times ten to the minus six.


title: Charmonium at CLEO-c

abstract:
  Results are presented on Charmonium using data collected with the CLEO III
and CLEO-c detectors at the Psi(2S) and Psi(3770). Measurements include, the
first observation of the hc(1P1) state, the electronic widths of the J/Psi and
Psi(2S), the two photon width of the Chic2 and hadronic decays of the Psi(2S).


title:
Measurement of the Transverse Single-Spin Asymmetry for Mid-rapidity
  Production of Neutral Pions in Polarized p+p Collisions at 200 GeV
  Center-of-Mass Energy

abstract:
  The spin structure of the proton has revealed itself to be extremely complex
and is an area of ongoing research. The Relativistic Heavy Ion Collider (RHIC)
at Brookhaven National Laboratory (BNL) inaugurated its operation as the first
polarized-proton collider during the 2001-2002 run, marking the beginning of a
new era in the study of proton spin structure.
  From the data collected in this run, the PHENIX experiment measured the
transverse single-spin asymmetry (A_N) for neutral pion production at x_F~0.0
over a transverse momentum range of 1 to 5 GeV/c from polarized proton-proton
interactions at a center-of-mass energy of 200 GeV and found it to be zero
within a few percent. Interest in these measurements arises from the
observation of large (~30%) transverse single-spin asymmetries in pion
production at forward angles by the E704 collaboration at Fermilab (sqrt{s} =
19.4 GeV), found by the STAR and BRAHMS experiments to persist at RHIC
energies, as well as single-spin, azimuthal asymmetries observed recently in
semi-inclusive deep-inelastic scattering experiments. Such large asymmetries
were initially surprising because at leading order, pQCD predicted only small
effects.
  Several possible origins of these large asymmetries have been proposed.
Despite great theoretical progress in recent years, no single, clear formalism
has emerged in which to interpret the available data. Further theoretical work
and a variety of additional experimental measurements will be necessary to
understand current results and elucidate the transverse spin structure of the
proton.


title:
Photoproduction of $K^{*+}\Lambda$ and $K^+\Sigma(1385)$ in the reaction
  $\gamma \lowercase{p} \to K^+ \Lambda \pi^0 $ at Jefferson Lab

abstract:
  The search for missing nucleon resonances using coupled channel analysis has
mostly been concentrated on $N\pi$ and $KY$ channels, while the contributions
of $K^*Y$ and $KY^*$ channels have not been investigated thoroughly mostly due
to the lack of data. With an integrated luminosity of about 75 $pb^{-1}$, the
photoproduction data using a proton target recently collected by the CLAS
Collaboration at Jefferson Lab with a photon energy range of 1.5-3.8 GeV
provided large statistics for the study of light hyperon photoproduction
through exclusive reactions. The reaction $\gamma p \to K^+ \Lambda \pi^0$ has
been investigated. Preliminary results of the $K^{*+}\Lambda$ and
$K^+\Sigma(1385)$ cross sections are not negligible compared with the $KY$
channels. The $\Lambda \pi^0$ invariant mass spectrum is dominated by the
$\Sigma(1385)$ signal and no significant structure was found around the
$\Sigma(1480)$ region.


title:
$\Xi$ spectroscopy in photoproduction on a proton target at Jefferson
  Lab

abstract:
  The CLAS Collaboration at Jefferson Lab conducted a photoproduction
experiment on a proton target using a tagged photon beam with an energy range
of 1.5-3.8 GeV during May-July 2004. With an integrated luminosity of about 75
$pb^{-1}$, this experiment provides the largest data set for photon-proton
reactions ever collected. The reaction $\gamma p \to K^+K^+\Xi^{-}(1320)$ has
been investigated and the preliminary results of the cross section measurement
of $\Xi^-(1320)$ for the photon energy range of 2.7-3.8 GeV have been obtained.
In a search for excited cascade states, the reaction of $\gamma p \to
K^+K^+\pi^-(\Xi^0(1320))$ has also been explored.


title: Heavy Flavor Production in CDF II Detector

abstract:
  For data collected with the CDF Run II detector, measurements of the charm
and bottom production cross-sections are presented. The results are based both
on large samples of fully reconstructed hadron decay products of charm and
bottom made available by the tracking triggers and on a calorimeter jet
triggered sample tagged by the presence of a secondary vertex. The experimental
data are compared with theoretical predictions from recent next-to-leading
order (NLO) QCD calculations.


title: Particle Production and Fragmentation at HERA

abstract:
  Recent results from HERA are presented on a range of topics: charged
multiplicities, production of non-strange mesons and strange particles, charm
fragmentation, baryons decaying to strange particles, antideuteron production,
Bose-Einstein correlations, and new interpretations of results on prompt photon
production in DIS.


title: Backgrounds in Neutrino Appearance Signal at MiniBooNE

abstract:
  The MiniBooNE (Booster Neutrino Experiment) experiment is a precise search
for neutrino oscillations but is crucially sensitive to background processes
that would mimic an oscillation signal. The background sources include
intrinsic $\nu_{e}$ from kaon and muon decays, mis-identified $\pi^{0}$, gammas
from radiative delta decays, and muon neutrino events mis-identified as
electrons. A summary of these backgrounds and the tools to handle them is
presented.


abstract:
  We report on studies of Bose-Einstein correlations and color reconnection in
hadronic W pair production at LEP.
  Bose-Einstein correlations between identical particles from the decay of
different W's are studied by comparing the particle correlation in hadronic W
pair decays to those in events which are constructed from the combination of
the hadronic parts of two events where one of the Ws decays leptonicaly. The
LEP combined result of the strength of the effect is consistent with zero and
can be used to limit the systematic uncertainty due to Bose-Einstein
correlations on the W mass measurements.
  Color reconnection is expected to affect the production of particles in
hadronic decays of W pairs. Measurements of inclusive charged particle
multiplicities, and of their angular distribution with respect to the four jet
axes of the events, are used to test models of color reconnection.
  The results are both consistent with models without color reconnection and
models with moderate color reconnection. They can be used to exclude more
extreme models of color reconnection and thereby limit the uncertainty due to
color reconnection on the W mass measurement.


title: Inclusive jet cross-sections and dijet azimuthal decorrelations with D0

abstract:
  We present a preliminary measurement of the inclusive jet cross-sections
based on an integrated luminosity of 378 pb^{-1} acquired with the D0 detector
between 2002 and 2004 at a center of mass energy of \sqrt{s}=1.96 TeV and a
measurement of azimuthal dijet decorrelations based on an integrated luminosity
of 150 pb^{-1}. The cross section measurements are based on an iterative cone
algorithm with a cone size of R=0.7. They are performed in two rapidity bins
between 0.0 and 0.8. The measurements are in good agreement with next to
leading order calculations.
  The azimuthal angle between the two leading jets is sensitive to higher order
QCD effects. The measurement of dijet azimuthal decorrelations therefore probes
these effects without explicitly reconstructing more than two jets.
  Except for large azimuthal angles where soft effects are important the
measurements are well described by the next to leading order perturbation
theory.


title:
Measurements of $\Lambda^+_c$ Branching Fractions of Cabibbo-Suppressed
  Decay Modes involving $\Lambda$ and $\Sigma^{0}$

abstract:
  We measure the branching ratios of the Cabibbo-suppressed decays
$\Lambda^+_c$ $\to$ $\Lambda$ $K^+$ and $\Lambda^+_c$ $\to$ $\Sigma^{0}$ $K^+$
%(measured with improved accuracy). relative to the Cabibbo-favored decay modes
$\Lambda^+_c$ $\to$ $\Lambda$ $\pi^+$ and $\Lambda^+_c$ $\to$ $\Sigma^{0}$
$\pi^+$ to be $ 0.044 \pm 0.004 (\textnormal{stat.}) \pm 0.003 \
(\textnormal{syst.})$ and $ 0.039 \pm 0.005 (\textnormal{stat.}) \pm 0.003
(\textnormal{syst.})$, respectively. We set an upper limit on the branching
ratio at 90 % confidence level for $\Lambda^+_c$ $\to$ $\Lambda$ $K^+ \pi^+
\pi^-$ to be $ 4.1 \times 10^{-2}$ relative to $\Lambda^+_c$ $\to$ $\Lambda$
$\pi^+$ and for $\Lambda^+_c$ $\to$ $\Sigma^{0}$ $K^+ \pi^+ \pi^-$ to be $ 2.0
\times 10^{-2}$ relative to $\Lambda^+_c$ $\to$ $\Sigma^{0}$ $\pi^+$. We also
measure the branching fraction for the Cabibbo-favored mode $\Lambda^+_c$ $\to$
$\Sigma^{0}$ $\pi^+$ relative to $\Lambda^+_c$ $\to$ $\Lambda$ $\pi^+$ to be
$0.977 \pm 0.015 (\textnormal{stat.}) \pm 0.051 (\textnormal{syst.})$. This
analysis was performed using a data sample with an integrated luminosity of 125
fb$^{-1}$ collected by the $BABAR$ detector at the PEP-II asymmetric-energy $B$
factory at SLAC.


title: BaBar: sin(2beta+gamma)

abstract:
  The time-dependent CP asymmetries in fully reconstructed B0 --> D(*)pi/rho
decays (new preliminary result), and in partially reconstructed B0 --> D(*)pi
decays, are measured with the BaBar detector at the PEP-II asymmetric B factory
at SLAC, using 232 million Y(4S) -> BB decays. We combine the above results
and, using other measurements and theoretical assumptions, we interpret them in
terms of the angles of the unitarity triangle describing the
Cabibbo-Kobayashi-Maskawa matrix. We find |sin(2beta+gamma)|>0.64(0.42) at
68%(90%) confidence level using a frequentistic approach and |2beta+gamma|=(90
+- 43)o using a Bayesian approach.


title: Search for nuclearites with the SLIM detector

abstract:
  The strange quark matter (SQM) may be the ground state of QCD; nuggets of SQM
could be present in cosmic rays (CR). SLIM is a large area experiment, using
CR39 and Makrofol track etch detectors, presently deployed at the high altitude
CR Laboratory of Chacaltaya, Bolivia. We discuss the expected properties of
SQM, from the point of view of its search with SLIM. We present also some
preliminary results from SLIM.


title: ISR physics at BABAR

abstract:
  We present a review of BaBar results on e+e- annihilations into exclusive
hadronic final states using the initial state radiation technique. Cross
sections over the sqrt{s} range from threshold to 4.5 GeV, with very small
point-to-point systematic errors, are presented for the 3pi, 2(pi+ pi-), 3(pi+
pi-), 2(pi+ pi-)2pi0, K+ K- pi+ pi-, 2(K+ K-) and p anti-p final states. The
proton form factor and the ratio of its electric and magnetic components are
also presented.


title:
Limits on different Majoron decay modes of $^{100}$Mo and $^{82}$Se for
  neutrinoless double beta decays in the NEMO-3 experiment

abstract:
  The NEMO-3 tracking detector is located in the Fr\'ejus Underground
Laboratory. It was designed to study double beta decay in a number of different
isotopes. Presented here are the experimental half-life limits on the double
beta decay process for the isotopes $^{100}$Mo and $^{82}$Se for different
Majoron emission modes and limits on the effective neutrino-Majoron coupling
constants. In particular, new limits on "ordinary" Majoron (spectral index 1)
decay of $^{100}$Mo ($T_{1/2} > 2.7\cdot10^{22}$ y) and $^{82}$Se ($T_{1/2} >
1.5\cdot10^{22}$ y) have been obtained. Corresponding bounds on the
Majoron-neutrino coupling constant are $<g_{ee} > < (0.4-1.9) \cdot 10^{-4}$
and $< (0.66-1.7) \cdot 10^{-4}$.


title: Bringing the SciBar Detector to the Booster Neutrino Beam

abstract:
  This document presents the physics case for bringing SciBar, the fully
active, finely segmented tracking detector at KEK, to the FNAL Booster Neutrino
Beam (BNB) line. This unique opportunity arose with the termination of K2K beam
operations in 2005. The physics that can be done with SciBar/BNB can be put
into three categories, each involving several measurements. First are neutrino
cross section measurements which are interesting in their own right, including
analyses of multi-particle final states, with unprecedented statistics. Second
are measurements of processes that represent the signal and primary background
channels for the upcoming T2K experiment. Third are measurements which improve
existing or planned MiniBooNE analyses and the understanding of the BNB, both
in neutrino and antineutrino mode. SciBar and BNB have both been built and
operated with great success. As a result, the cost of SciBar/BNB is far less
than building a detector from scratch and both systems are well understood with
existing detailed and calibrated Monte Carlo simulations. The performance
expectations assumed in this document are therefore well-grounded in reality
and carry little risk of not meeting expectations.


title:
W and Z boson production in $p\bar p$ collisions from Run II of the
  Tevatron Collider

abstract:
  Measurements of inclusive W and Z cross sections times leptonic branching
ratios for $p\bar p$ collisions at $\sqrt s$=1.96 TeV are reported here on
behalf of the CDF and D0 collaborations. The data correspond t an integrated
luminosity up to 200 $pb\_-1$. The ratio of leptonic W and Z rates is measured
and the leptonic branching fraction $B(W \to \ell\nu)$ is extracted as well as
an indirect value for the total width of teh W and the CKM matrix element
$|Vcs|$.


title:
Measurement of the branching fraction, polarization, and CP asymmetry
  for B0->rho+rho- decays, and determination of the CKM phase phi_2

abstract:
  We have measured the branching fraction B, longitudinal polarization fraction
f_L, and CP asymmetry coefficients A and S for B0->rho+rho- decays with the
Belle detector at the KEKB e+e- collider using 253 fb-1 of data. We obtain B =
[22.8 +-3.8 (stat) +2.3 -2.6 (syst) ] x 10-6, f_L = 0.941 +0.034 -0.040 (stat)
+-0.030 (syst), A = 0.00 +-0.30 (stat) +-0.09 (syst), and S = 0.08 +-0.41
(stat) +-0.09 (syst). These values are used to constrain the
Cabibbo-Kobayashi-Maskawa phase phi_2; the solution consistent with the
Standard Model is phi_2 = (88 +-17) degrees or 59 deg.< phi_2 < 115 deg. at 90%
CL.


title:
Precise measurement of Gamma(Ks->pi+pi-(gamma))/Gamma(Ks->pi0pi0) with
  the KLOE detector at DAFNE

abstract:
  Using a sample of over 400 million phi->KsKl decays produced during the years
2001 and 2002 at the DAFNE e+e- collider, the ratio
R=Gamma(Ks->pi+pi-(g))/Gamma(Ks->pi0pi0) has been measured with the KLOE
detector. The result is
R=2.2555+-0.0012(stat)+-0.0021(syst-stat)+-0.0050(syst), which is in good
agreement with the previously published result based on the KLOE data sample
from the year 2000. The average of the KLOE results is R=2.2549+-0.0054,
reducing the total error by a factor of three, to 0.25%.


title:
Study of the branching ratio and charge asymmetry for the decay Ks->pi e
  nu with the KLOE detector

abstract:
  Among some 400 million KsKl pairs produced in e+e- annihilations at DAFNE,
about 6500 each of Ks->pi+e-nubar and Ks->pi-e+nu decays have been observed
with the KLOE detector. From these, the ratio
G(Ks->pienu)/G(Ks->p+p-(g))=(10.19+-0.13)10-4 is obtained, improving the
accuracy on BR(Ks->pienu) by a factor of four and providing the most precise
test of the DeltaS=DeltaQ rule. From the partial width Gamma(Ks->pienu), a
value for f+(K0)Vus is obtained that is in agreement with unitarity of the
quark-mixing matrix. The lepton charge asymmetry AS=(1.5+-9.6stat+-2.9syst)10-3
is compatible with the requirements of CPT invariance. The form-factor slope
agrees with recent results from semileptonic Kl and K+ decays. These are the
first measurements of the charge asymmetry and form-factor slope for
semileptonic Ks decays.


title:
Experimental Limits on Weak Annihilation Contributions to b -->u ell nu
  Decay

abstract:
  We present the first experimental limits on high-q^2 contributions to
charmless semileptonic B decays of the form expected from the Weak Annihilation
(WA) decay mechanism. Such contributions could bias determinations of |Vub|
from inclusive measurements of B-> X_u lnu. Using a wide range of models based
on available theoretical input we set a limit of (Gamma_WA/Gamma_b->u) < 7.4%
(90% confidence level) on the WA fraction, and assess the impact on previous
inclusive determinations of |Vub|.


title: Beyond the Standard Model at HERA: Status and Prospects

abstract:
  An overview of experimental results on searches for new phenomena at HERA is
presented. The complementarity with searches performed at other experiments is
discussed and the prospects for a discovery, using the full HERA data to be
delivered until mid-2007, are presented.


title:
Improved Constraints on D0-D0bar Mixing in D0 -> K+ pi- Decays from the
  Belle Detector

abstract:
  We report the results of a search for D0-D0bar mixing in D0 -> K+ pi- decays
based on 400 fb^{-1} of data accumulated by the Belle detector at KEKB. Both
assuming CP conservation and allowing for CP violation, we fit the decay-time
distribution for the mixing parameters x' and y', as well as for the parameter
R_D, the ratio of doubly-Cabibbo-suppressed decays to Cabibbo-favored decays.
The 95% confidence level region in the (x'^2,y') plane is obtained using a
frequentist method. Assuming CP conservation, we find x'^2<0.72 x 10^{-3} and
-9.9 x 10^{-3}<y'<6.8 x 10^{-3} at the 95% confidence level; these are the most
stringent constraints on the mixing parameters to date. The no-mixing point
(0,0) has a confidence level of 3.9%. Assuming no mixing, we measure
R_D=(0.377+-0.008+-0.005)%.


title: Low energy neutron propagation in MCNPX and GEANT4

abstract:
  Simulations of neutron background from rock for underground experiments are
presented. Neutron propagation through two types of rock, lead and hydrocarbon
material is discussed. The results show a reasonably good agreement between
GEANT4, MCNPX and GEANT3 in transporting low-energy neutrons.


title: Hard Diffractive Results and Prospects at the Tevatron

abstract:
  We review hard diffractive results and prospects at the Tevatron with an
emphasis on factorization breaking in diffractive processes. Upper limits on
the exclusive di-jet and chi_c^0 production cross sections at CDF and the
status of the D0 Forward Proton Detectors are discussed.


title: Study of B+- --> D_CP K+- and D^*_CP K+- decays

abstract:
  We report a study of the modes D_CP K+- and D^*_CP K+- where D^(*) decays to
CP eigenstates. The data sample used contains 275 x 10^6 BB events at the
Upsilon(4S) resonance collected by the Belle detector at the KEKB
energy-asymmetric e^+ e^- collider. The CP asymmetries obtained for D_CP K are:
A_1 = 0.06 +- 0.14 (stat) +- 0.05 (sys), A_2 = -0.12 +- 0.14 (stat) +- 0.05
(sys) and for D^*_CP K : A_1^* = -0.20 +- 0.22 (stat) +- 0.04 (sys), A_2^* =
0.13 +- 0.30 (stat) +- 0.08 (sys).


title:
Test of lepton universality and search for lepton flavor violation in
  Upsilon(1S,2S,3S) decays at CLEO

abstract:
  We present the analysis technique and preliminary results of two ongoing
analyses at CLEO which put lepton universality and lepton flavor conservation
to the test in Upsilon decays.


title: Direct Measurement of \DeltaG/G at Compass

abstract:
  The gluon polarization $\Delta{G}/G$ is the key to a further clarification of
the spin structure of the nucleon. The COMPASS collaboration at CERN has set
out to undertake the direct determination of this quantity. It accesses the
gluon distribution via the photon-gluon fusion process (PGF) in scattering
polarized muons off a polarized deuteron target. And it explores three
different channels to tag the PGF: open charm production and high transverse
momentum (high p_T), in either electroproduction (Q^2 > 1 GeV^2) or quasi-real
photoproduction (Q^2 < 1 GeV^2).
  The high p_T quasi-real photoproduction channel yields the most precise
measurement. The result indicates that the gluon polarization is small. I
describe its experimental aspects and its theoretical framework, based on
PYTHIA. And I report on the preliminary results obtained in the other two
channels, and on the prospects for future analysis and data taking.


title:
CNO and pep neutrino spectroscopy in Borexino: Measurement of the deep
  underground production of cosmogenic 11C in organic liquid scintillator

abstract:
  Borexino is an experiment for low energy neutrino spectroscopy at the Gran
Sasso underground laboratories. It is designed to measure the mono-energetic
$^7$Be solar neutrino flux in real time, via neutrino-electron elastic
scattering in ultra-pure organic liquid scintillator. Borexino has the
potential to also detect neutrinos from the \emph{pep} fusion process and the
CNO cycle. For this measurement to be possible, radioactive contamination in
the detector must be kept extremely low. Once sufficiently clean conditions are
met, the main background source is $^{11}$C, produced in reactions induced by
the residual cosmic muon flux on $^{12}$C. In the process, a free neutron is
almost always produced. $^{11}$C can be tagged on an event by event basis by
looking at the three-fold coincidence with the parent muon track and the
subsequent neutron capture on protons. This coincidence method has been
implemented on the Borexino Counting Test Facility data. We report on the first
event by event identification of \emph{in situ} muon induced $^{11}$C in a
large underground scintillator detector. We measure a $^{11}$C production rate
of 0.130 $\pm$ 0.026 (stat) $\pm$ 0.014 (syst) day$^{-1}$ ton$^{-1}$, in
agreement with predictions from both experimental studies performed with a muon
beam on a scintillator target and \emph{ab initio} estimations based on the
$^{11}$C producing nuclear reactions.


title: Upsilon and Chi_b analyses at CLEO

abstract:
  I detail recent work done by the CLEO collaboration using data gathered at
the CESR accelerator concerning the Upsilon system. Results include B_S
production at the Upsilon(5S), decays of the Upsilon(nS) (n=1,2,3) to tau
pairs, the Upsilon di-electron width, decays of the Upsilon to two hadrons and
a photon, and the observation of the first di-pion transition between chi_b
states.


title: Search for Higgs and New Phenomena at Colliders

abstract:
  The present status of searches for the Higgs boson(s) and new phenomena is
reviewed. The focus is on analyses and results from the current runs of the
HERA and Tevatron experiments. The LEP experiments have released their final
combined MSSM Higgs results for this conference. Also included are results from
sensitivity studies of the LHC experiments and lepton flavour violating
searches from the B factories, KEKB and PEP-II.


title:
Measurement of the Form-Factor Slopes for the Decay KLe3 with the KLOE
  Detector

abstract:
  We present a measurement of the K-pi vector current form-factor parameters
for the Ke3 decay. We use 328 pb$^{-1}$ of data collected in 2001 and 2002,
corresponding to about 2 million Ke3 events.
  Measurements of semileptonic form factors provide information about the
dynamics of the strong interaction and are necessary for evaluation of the
phase-space integral Ie_K needed to measure the CKM matrix element Vus for Ke3
decays.
  Our result is $l=(28.6\pm0.5\pm0.4)10^{-3}$ for a linear fit, and
$l'=(25.5\pm1.5\pm1.0)10^{-3}$, $l''=(1.4\pm0.7\pm0.4)10^{-3}$ for a quadratic
fit.


title:
Transverse-longitudinal HBT correlations in proton-antiproton collisions
  at root(s) = 630 GeV

abstract:
  Correlations of like-sign pion pairs emerging from proton-antiproton
collisions are analysed in the two-dimensional (q_L,q_T) decomposition of the
three-momentum difference q. While the data cannot be adequately represented by
gaussian, exponential, power-law or Edgeworth parametrisations, more elaborate
ones such as Levy and an exponential with a cross term do better. A two-scale
model using a hard cut to separate small and large scales may indicate a core
that is more prolate than the halo. Consideration not only of the interference
peak at small (q_L,q_T), but also of the shape of the correlation distribution
at intermediate momentum differences is crucial to understanding the data.


title:
Single Intermediate Vector Boson production in e+e- collisions at
  sqrt(s) = 183 - 209 GeV

abstract:
  The production of single charged and neutral intermediate vector bosons in
e+e- collisions has been studied in the data collected by the DELPHI experiment
at LEP at centre-of-mass energies between 183 and 209 GeV, corresponding to an
integrated luminosity of about 640 pb^{-1}. The measured cross-sections for the
reactions, determined in limited kinematic regions, are in agreement with the
Standard Model predictions.


title: D0 Search for the Higgs Boson in Multijet Events

abstract:
  We present two searches for the Higgs boson in \sqrt{s} = 1.96 TeV
p\bar{p}collisions using data taken with the \dz detector during Run II of the
Fermilab Tevatron collider. The first study is a search for neutral Higgs
bosons produced in association with bottom quarks. We set upper limits on the
production of neutral Higgs bosons in the mass range of 90 to 150 GeV.The
second study is a search for the standard model Higgs boson produced in
association with the Z boson. We study the p\bar{p}\to ZH \to \nu \bar{\nu} b
\bar{b} channel, which is one of the most sensitive ways to search for light
Higgs bosons at the Tevatron. We search for a peak in invariant mass
distribution of two b-tagged jets. After subtracting the backgrounds, we set
the 95% C.L. upper limits on the \sigma(p\bar{p} \to ZH \to \nu \bar{\nu})
\times BR(H) \to b\bar{b}) for Higgs masses between 105 and 135 GeV.


title:
Search for eta_b in two-photon collisions at LEP II with the DELPHI
  detector

abstract:
  The pseudoscalar meson eta_b has been searched for in two-photon interactions
at LEP II. The data sample corresponds to a total integrated luminosity of 617
pb^{-1} at centre-of-mass energies ranging from 161 to 209 GeV. Upper limits at
a confidence level of 95% on the product Gamma_{\gamma\gamma}(eta_b) x
BR(eta_b) are 190, 470 and 660 eV/c^2 for the eta_b decaying into 4, 6 and 8
charged particles, respectively.


title:
Shortest movie: Bose-Einstein correlation functions in e+e-
  annihilations

abstract:
  Bose-Einstein correlations of identical charged-pion pairs produced in
hadronic Z decays are analyzed in terms of various parametrizations. A good
description is achieved using Levy stable distributions. The source function is
reconstructed with the help of the tau-model.


title:
First Measurements of the Exclusive Decays of the Upsilon(5S) to B Meson
  Final States and Improved B^*_s Mass Measurement

abstract:
  Using 420 pb^-1 of data collected on the Upsilon(5S) resonance with the CLEO
III detector, we reconstruct B mesons in 25 exclusive decay channels to measure
or set upper limits on the decay rate of Upsilon(5S) into B meson final states.
We measure the inclusive B cross-section to be
sigma(Y(5S)-->BB(X))=(0.176+-0.030+-0.016) nb and make the first measurements
of the production rates of sigma(Y(5S)-->B*B*)=(0.131+-0.025+-0.014) nb and
sigma(Y(5S)-->BB*)=(0.043+-0.016+-0.006) nb, respectively. We set 90%
confidence level limits of sigma(Y(5S)-->B B-bar)<0.038 nb,
sigma(Y(5S)-->B(*)B(*)(pi))<0.055 nb and sigma(Y(5S)-->BBpipi)<0.024 nb. We
also extract the most precise value of the B_s* mass to date,
M(B_s*)=(5411.7+-1.6+-0.6) MeV/c^2.


title: Measurement of the Running of the Electromagnetic Coupling at LEP

abstract:
  The study of low-angle and large-angle Bhabha scattering at LEP gives access
to the running of the electromagnetic coupling. Two recent measurements of the
OPAL and L3 collaborations probe the running of alpha in the regions
1.8GeV^2<-Q^2<6.1GeV^2 and 1800GeV^2 <-Q^2 <21600GeV^2, respectively. The
strategies and the results of these studies are presented. A global overview is
given of the agreement of these and previous L3 findings with the QED
predictions.


title:
Determinations of |Vub| from Inclusive Semileptonic B Decays with
  Reduced Model Dependence

abstract:
  We report two novel determinations of |Vub| with reduced model dependence,
based on measurements of the mass distribution of the hadronic system in
semileptonic B decays. Events are selected by fully reconstructing the decay of
one B meson and identifying a charged lepton from the decay of the other B
meson from Y(4S) to BBbar events. In one approach, we combine the inclusive B
to X_u l nu rate, integrated up to a maximum hadronic mass m_X < 1.67GeV, with
a measurement of the inclusive B to X_s gamma photon energy spectrum. We obtain
|Vub| = (4.43 +- 0.38stat +- 0.25syst +- 0.29theo)*10^-3. In another approach
we measure the total B to X_u l nu rate over the full phase space and find
|Vub| = (3.84 +- 0.70stat +- 0.30syst +- 0.10theo)*10^-3.


title:
Search for Pair Production of Second Generation Scalar Leptoquarks in
  ppbar Collisions at sqrt(s)=1.96 TeV

abstract:
  We report on a search for the pair production of second generation scalar
leptoquarks (LQ_2) in ppbar collisions at the center-of-mass energy sqrt(s) =
1.96 TeV, using data corresponding to an integrated luminosity of 294 +- 19
pb^-1 recorded with the D0 detector. No evidence for a leptoquark signal in the
LQ_2 LQ_2 -> muq muq channel has been observed, and upper bounds on the product
of cross section times branching fraction were set. This yields lower mass
limits of m(LQ_2) > 247 GeV for beta = Br(LQ_2->muq) = 1 and m(LQ_2) > 182 GeV
for beta = 1/2. Combining these limits with previous D0 results, the lower
limits on the mass of a second generation scalar leptoquark are m(LQ_2) > 251
GeV and m(LQ_2) > 204 GeV for beta = 1 and beta = 1/2, respectively.


title:
Measurement of the Strong Coupling alpha s from Four-Jet Observables in
  e+e- Annihilation

abstract:
  Data from e+e- annihilation into hadrons at centre-of-mass energies between
91 GeV and 209 GeV collected with the OPAL detector at LEP, are used to study
the four-jet rate as a function of the Durham algorithm resolution parameter
ycut. The four-jet rate is compared to next-to-leading order calculations that
include the resummation of large logarithms. The strong coupling measured from
the four-jet rate is alphas(Mz0)=
0.1182+-0.0003(stat.)+-0.0015(exp.)+-0.0011(had.)+-0.0012(scale)+-0.0013(mass)
in agreement with the world average. Next-to-leading order fits to the
D-parameter and thrust minor event-shape observables are also performed for the
first time. We find consistent results, but with significantly larger
theoretical uncertainties.


title: Inclusive diffraction

abstract:
  Results are given on the measurements of the hard diffractive interactions at
HERA $ep$ collider. The structure of the diffractive exchange in terms of
partons and the factorisation properties are discussed, in particular by
comparing the QCD predictions for dijets and $D^*$ with measurements both in
the photo and electroproduction regimes.


title:
Comparison of longitudinal polarization of $\Lambda$ and $\bar\Lambda$
  in deep-inelastic scattering at COMPASS

abstract:
  The longitudinal polarization of Lambda and anti-Lambda hyperons produced in
deep-inelastic scattering of 160 GeV/c polarized muons is studied in the
COMPASS experiment. Preliminary results on x- and y- dependence of the
longitudinal polarization of Lambda and anti-Lambda from data collected during
the 2003 run are presented.


title: Hadron Spectroscopy in electrons-protons Collisions at HERA

abstract:
  Recent results from H1 and ZEUS on searches for exotic baryons in $ep$
collisions at HERA are reviewed. Evidence for the production of the strange
pentaquark $\Theta^+$ and of a narrow anti-charmed baryon decaying to $D^{*-}
p$ together with negative results of pentaquark searches at HERA are presented.


title:
Improved Measurement of Double Helicity Asymmetry in Inclusive
  Midrapidity pi^0 Production for Polarized p+p Collisions at sqrt(s)=200 GeV

abstract:
  We present an improved measurement of the double helicity asymmetry for pi^0
production in polarized proton-proton scattering at sqrt(s) = 200 GeV employing
the PHENIX detector at the Relativistic Heavy Ion Collider (RHIC). The
improvements to our previous measurement come from two main factors: Inclusion
of a new data set from the 2004 RHIC run with higher beam polarizations than
the earlier run and a recalibration of the beam polarization measurements,
which resulted in reduced uncertainties and increased beam polarizations. The
results are compared to a Next to Leading Order (NLO) perturbative Quantum
Chromodynamics (pQCD) calculation with a range of polarized gluon
distributions.


title:
Observation of Bs to Psi(2S)phi and Measurement of Ratio of Branching
  Fractions B (Bs --> Psi(2S)phi) / B (Bs --> J/Psi phi)

abstract:
  We report the first observation of Bs to Psi(2S) phi signals using 360 pb^-1
of CDF Run II data sample, where Psi(2S) decays into mu+mu- and J/psi pi+pi-
modes with phi decays to K+K-. We have measured the relative branching ratio of
Br(Bs to Psi(2S)phi)/Br(Bs to J/psi phi) using J/psi, Psi(2S) to mu+mu- decay
mode. We obtain Br(Bs to Psi(2S)phi)/Br(Bs to J/psi phi) = 0.52 +- 0.13 (stat.)
+- 0.04 (syst.) +- 0.06 (BR).


title:
The e+ e- --> 3(pi+pi-), 2(pi+pi-pi0) and K+K- 2(pi+pi-) Cross Sections
  at Center-of-Mass Energies from Production Threshold to 4.5 GeV Measured with
  Initial-State Radiation

abstract:
  We study the processes e+ e- --> 3(pi+pi-)gamma, 2(pi+pi-pi0)gamma and K+ K-
2(pi+pi-)gamma, with the photon radiated from the initial state. About 20,000,
33,000 and 4,000 fully reconstructed events, respectively, have been selected
from 232 fb-1 of BaBar data. The invariant mass of the hadronic final state
defines the effective e+e- center-of-mass energy, so that these data can be
compared with the corresponding direct e+e- measurements. From the 3(pi+pi-),
2(pi+pi-pi0) and K+ K- 2(pi+pi-) mass spectra, the cross sections for the
processes e+ e- --> 3(pi+pi-), e+ e- --> 2(pi+pi-pi0) and e+ e- --> K+ K-
2(pi+pi-) are measured for center-of-mass energies from production threshold to
4.5 GeV. The uncertainty in the cross section measurement is typically 6-15%.
We observe the J/psi in all these final states and measure the corresponding
branching fractions.


title: Jet production and measurements of $\alpha\_S$ at HERA

abstract:
  The inclusive jet, dijet and trijet production cross-sections in
deep-inelastic scattering (DIS) at $\sqrt{s}$=320GeV have been measured at the
electron-proton collider HERA by the H1 and ZEUS collaborations using data
taken in 1998-2000. The jet cross-sections have been measured differentially in
four-momentum transfer squared $Q^2$ and jet transverse energy in the
Breit-frame $E\_{T,B}$ with a typical precision of 5-10% limited by systematic
uncertainties such as hadronization corrections and hadronic energy scale. All
jet observables are well described by perturbative QCD ($\_pQCD$) predictions
at next-to-leading order (NLO) within the estimated accuracy of these
calculations which is limited by the absence higher orders, and which is in
general inferior to the experimental precision. The values for the coupling
constant $\alpha\_S$ of the strong interaction as determined by fits of
$\_pQCD$ predictions to the inclusive jet cross-section and the trijet-to-dijet
production ratio $R\_{3/2}$ are consistent for both experiments and both
observables, and also are in excellent agreement with the world average.
Combining the individual measurements, a common value of
$\alpha\_S=0.1186\pm0.0011(exp.)\pm$0.0050(theory) is obtained.


title:
Measurement of the Top Quark Mass using Template Methods on Dilepton
  Events in Proton-Antiproton Collisions at sqrt(s)=1.96 TeV

abstract:
  We describe a measurement of the top quark mass from events produced in
proton-antiproton collisions at a center-of-mass energy of 1.96 TeV, using the
Collider Detector at Fermilab. We identify top-antitop candidates where both W
bosons from the top quarks decay into leptons (electron, muon, or tau plus
neutrino) from a data sample of 360 inverse picobarns. The top quark mass is
reconstructed in each event separately by three different methods, which draw
upon simulated distributions of the neutrino pseudorapidity, top-antitop
longitudinal momentum, or neutrino azimuthal angle in order to extract
probability distributions for the top quark mass. For each method,
representative mass distributions, or templates, are constructed from simulated
samples of signal and background events, and parameterized to form continuous
probability density functions. A likelihood fit incorporating these
parameterized templates is then performed on the data sample masses in order to
derive a final top quark mass. Combining the three template methods, taking
into account correlations in their statistical and systematic uncertainties,
results in a top quark mass measurement of 170.1 +/- 6.0 (stat) +/- 4.1 (syst)
GeV/c^2.


title:
eRHIC - A precision electron-proton/ion collider facility at Brookhaven
  National Laboratory

abstract:
  An electron-proton/ion collider facility (eRHIC) is under consideration at
Brookhaven National Laboratory (BNL). Such a new facility will require the
design and construction of a new optimized detector profiting from the
experience gained from the H1 and ZEUS detectors operated at the HERA collider
at DESY. The details of the design will be closely coupled to the design of the
interaction region, and thus to the machine development work in general. An
overview of the accelerator and detector design concepts will be provided.


title: Searching for neutrino oscillations with OPERA

abstract:
  The OPERA experiment will search for neutrino oscillations using a muon
neutrino beam and a hybrid emulsion-scintillator detector. Basic principles,
current status and expected performance of the experiment are discussed.


title: NEMO-3 and SuperNEMO double beta decay experiments

abstract:
  Latest results on $\beta\beta 0 \nu$, $\beta\beta 0 \nu\chi^0$ and
$\beta\beta 2 \nu$ decays of different isotopes from NEMO-3 double beta decay
experiment are presented. In particular, new limits on neurtinoless double beta
decay of $^{100}Mo$ and $^{82}Se$ have been obtained, $T_{1/2} > 4.6\times
10^{23}$ y and $T_{1/2} > 1\times 10^{23}$ y, respectively. A possible next
step with SuperNEMO detector is discussed.


title: Transverse Spin and RHIC

abstract:
  The Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory
is the first accelerator facility that can accelerate, store and collide spin
polarized proton beams. This development enables a physics program aimed at
understanding how the spin of the proton results from its quark and gluon
substructures. Spin states that are either parallel (longitudinal) or
perpendicular (transverse) to the proton momentum reveal important insight into
the structure of the proton. This talk outlines future plans for further
studies of transverse spin physics at RHIC.


title: Transversity Physics at Compass

abstract:
  Transverse spin physics is an important part of the scientific programme of
the COMPASS experiment at CERN, which started taking data in 2002, scattering
160 GeV/c muon beam on a polarized $^6$LiD target. The analysis of the data
taken with the target polarized orthogonally to the muon beam direction has
allowed to measure for the first time the Collins and Sivers asymmetries of the
deuteron. Both for the positive and the negative hadrons produced in
semi-inclusive DIS the measured asymmetries are small and, within errors,
compatible with zero: results on part of the accumulated statistics have
already been published. Two-hadron asymmetries and $\Lambda$ polarization
transfered from the struck quark are also being investigated, and preliminary
results on the data collected in the years 2002 and 2003 are given.


title: Search for direct CP violation in the decays K\pm \to 3\pi\pm

abstract:
  We report a measurement of the direct CP violation asymmetry parameter $A_g$
in charged kaon decays $K^\pm\to\pi^\pm\pi^+\pi^-$ by the NA48/2 experiment at
the CERN SPS. The experiment has been designed not to be limited by systematics
in the asymmetry measurement. Using $1.67\times 10^9$ such decays collected
during the 2003 run, the charge asymmetry in the Dalitz plot linear slope
parameter $g$ has been measured to be $A_g=(1.7\pm2.9)\times 10^{-4}$. The
precision of the result is limited by the statistics used.


title:
Differential cross section and photon beam asymmetry for the gamma n ->
  K+ Sigma- reaction at Egamma=1.5-2.4 GeV

abstract:
  Differential cross sections and photon beam asymmetries have been measured
for the gamma n -> K+ Sigma- and gamma p -> K+ Sigma0 reactions separately
using liquid deuterium and hydrogen targets with incident linearly polarized
photon beams of Egamma=1.5-2.4 GeV at 0.6<cosTheta<1. The cross section ratio
of sigma(K+Sigma-)/sigma(K+Sigma0), expected to be 2 on the basis of the
isospin 1/2 exchange, is found to be close to 1. For the K+Sigma- reaction,
large positive asymmetries are observed indicating the dominance of the
K*-exchange. A large difference between the asymmetries for the K+Sigma- and
K+Sigma0 reactions can not be explained by simple theoretical considerations.


title:
A Determination of the Centre-of-Mass Energy at LEP2 using Radiative
  2-fermion Events

abstract:
  Using e+e- -> mu+mu-(gamma) and e+e- -> qqbar(gamma) events radiative to the
Z pole, DELPHI has determined the centre-of-mass energy, sqrt{s}, using energy
and momentum constraint methods. The results are expressed as deviations from
the nominal LEP centre-of-mass energy, measured using other techniques. The
results are found to be compatible with the LEP Energy Working Group estimates
for a combination of the 1997 to 2000 data sets.


title: A new parameterization of the nucleon elastic form factors

abstract:
  The nucleon elastic form factors are generally interpreted as a mapping of
the charge and magnetic current distributions of the proton and neutron. New
high Q^2 measurements have opened up fundamental questions about G_ep that
remain to be answered. This talk will summarize current developments
surrounding the nucleon form factors and explain why they are important to
neutrino physicists. New parameterizations of the nucleon form factors,
suitable for use by neutrino physicists, will be introduced and discussed.


title: MiniBooNE

abstract:
  The physics motivations, design, and status of the Booster Neutrino
Experiment at Fermilab, MiniBooNE, are briefly discussed. Particular emphasis
is given on the ongoing preparatory work that is needed for the MiniBooNE muon
neutrino to electron neutrino oscillation appearance search. This search aims
to confirm or refute in a definitive and independent way the evidence for
neutrino oscillations reported by the LSND experiment.


title: D0 measurement of the dijet azimuthal decorrelations

abstract:
  We present the D0 measurement of correlations in the azimuthal angle between
the two largest transverse momentum jets produced in ppbar collisions at a
center-of-mass energy 1.96 TeV in the central rapidity region. The results are
based on an inclusive dijet event sample corresponding to an integrated
luminosity of 150/pb. Data is in good agreement with next-to-leading order pQCD
calculations, and with tuned Pythia, Herwig, Alpgen and Sherpa event
generators.


title:
An Improved Experimental Limit on the Electric Dipole Moment of the
  Neutron

abstract:
  An experimental search for an electric-dipole moment (EDM) of the neutron has
been carried out at the Institut Laue-Langevin (ILL), Grenoble. Spurious
signals from magnetic-field fluctuations were reduced to insignificance by the
use of a cohabiting atomic-mercury magnetometer. Systematic uncertainties,
including geometric-phase-induced false EDMs, have been carefully studied. Two
independent approaches to the analysis have been adopted. The overall results
may be interpreted as an upper limit on the absolute value of the neutron EDM
of |d_n| < 2.9 x 10^{-26} e cm (90% CL).


title: Diffraction and Total Cross-Section at the Tevatron and the LHC

abstract:
  At the Tevatron, the total p_bar-p cross-section has been measured by CDF at
546 GeV and 1.8 TeV, and by E710/E811 at 1.8 TeV. The two results at 1.8 TeV
disagree by 2.6 standard deviations, introducing big uncertainties into
extrapolations to higher energies. At the LHC, the TOTEM collaboration is
preparing to resolve the ambiguity by measuring the total p-p cross-section
with a precision of about 1 %. Like at the Tevatron experiments, the
luminosity-independent method based on the Optical Theorem will be used. The
Tevatron experiments have also performed a vast range of studies about soft and
hard diffractive events, partly with antiproton tagging by Roman Pots, partly
with rapidity gap tagging. At the LHC, the combined CMS/TOTEM experiments will
carry out their diffractive programme with an unprecedented rapidity coverage
and Roman Pot spectrometers on both sides of the interaction point. The physics
menu comprises detailed studies of soft diffractive differential
cross-sections, diffractive structure functions, rapidity gap survival and
exclusive central production by Double Pomeron Exchange.


title: Cross-section measurements in the NOMAD experiment

abstract:
  The NOMAD experiment collected valuable neutrino data samples, matching both
the large statistics of massive calorimeters and the reconstruction quality of
bubble chambers. This paper describes the recent measurements of neutrino
cross-sections on carbon target. The approach followed for cross-section
modeling is also explained.


title:
Measurements of the B to D* Form Factors Using the Decay B0 --> D* e
  nu_e

abstract:
  We measure the dependence of $\bar B^0 \to D^{*+}e^-\bar{\nu}_e$ on the decay
angles and momentum transfer. The data sample consists of $\sim 86 \times 10^6$
$B\bar B$-pairs accumulated on the $\Upsilon(4{\rm S})$ resonance by the BABAR
detector at the asymmetric $e^+ e^-$ collider PEP-II. We specify the three form
factors by two ratios $R_1$ and $R_2$, and by a single parameter $\rho^2$
characterizing the polynomial representing $h_{A_1}$, the function which
describes the momentum-transfer dependence of the form factor $A_1$. We
determine $R_1$, $R_2$, and $\rho^2$ using an unbinned maximum likelihood fit
to the full decay distribution. The results are $R_1=1.396\pm 0.060\pm 0.035\pm
0.027$, $R_2=0.885\pm 0.040\pm 0.022\pm 0.013$, and $\rho^2=1.145\pm 0.059\pm
0.030\pm 0.035$. The stated uncertainties are the statistical from the data,
statistical from the size of the Monte Carlo sample and the systematic
uncertainty, respectively. In addition, based on this measurement, we give an
updated value for the CKM matrix element $|V_{cb}|$.


title: Progress in Top Quark Physics

abstract:
  Experimental measurements of the properties of the top quark have improved
and will continue to improve significantly, with the excellent operation of the
CDF and D0 experiments and the Tevatron $p\bar{p}$ collider at the Fermi
National Accelerator Laboratory. All of the final state experimental signatures
from top quark production and decay are being analysed to test if this most
massive quark is sensitive to new physics beyond the standard model. So far,
observations are consistent with the standard model. New techniques have
dramatically improved the precision of the top quark mass measurement to 1.7%
and set the stage for a sub-1% measurement by 2008. This improved knowledge of
the top quark mass sharpens the standard model prediction for the mass of the
undiscovered Higgs boson, with implications for Higgs studies at the future LHC
and ILC.


title: TOTEM Physics

abstract:
  This article discusses the physics programme of the TOTEM experiment at the
LHC. A new special beam optics with beta* = 90 m, enabling the measurements of
the total cross-section, elastic pp scattering and diffractive phenomena
already at early LHC runs, is explained. For this and the various other TOTEM
running scenarios, the acceptances of the leading proton detectors and of the
forward tracking stations for some physics processes are described.


title:
Measurement of high-Q^2 deep inelastic scattering cross sections with a
  longitudinally polarised positron beam at HERA

abstract:
  The cross sections for charged and neutral current deep inelastic scattering
in e^+p collisions with a longitudinally polarised positron beam have been
measured using the ZEUS detector at HERA. The results, based on data
corresponding to an integrated luminosity of 23.8 pb^-1 at sqrt(s) = 318 GeV,
are given for both e^+p charged current and neutral current deep inelastic
scattering for both positive and negative values of the longitudinal
polarisation of the positron beam. Single differential cross sections are
presented for the kinematic region Q^2 > 200 GeV^2 . The measured cross
sections are compared to the predictions of the Standard Model. A fit to the
data yields sigma^CC (P_e = -1) = 7.4 +/- 3.9 (stat.) +/- 1.2 (syst.) pb, which
is consistent within two standard deviations with the absence of right-handed
charged currents in the Standard Model.


title:
Search for electron antineutrino interactions with the Borexino Counting
  Test Facility at Gran Sasso

abstract:
  Electron antineutrino interactions above the inverse beta decay energy of
protons ($E_\bar{\nu}_e>$1.8) where looked for with the Borexino Counting Test
Facility (CTF). One candidate event survived after rejection of background,
which included muon-induced neutrons and random coincidences. An upper limit on
the solar $\bar{\nu}_{e}$ flux, assumed having the $^8$B solar neutrino energy
spectrum, of 1.1$\times10^{5}$ cm$^{-2}$~s$^{-1}$ (90% C.L.) was set with a 7.8
ton $\times$ year exposure. This upper limit corresponds to a solar neutrino
transition probability, $\nu_{e} \to \bar{\nu}_{e}$, of 0.02 (90% C.L.).
Predictions for antineutrino detection with Borexino, including geoneutrinos,
are discussed on the basis of background measurements performed with the CTF.


title: Searches for New Physics at HERA

abstract:
  The latest results from the H1 and ZEUS collaborations are presented on rare
Standard Model processes and searches for physics Beyond the Standard Model.
Intriguing events containing high transverse momentum leptons are observed by
H1 and many competitive limits are set by both collaborations on the production
of new particles in a variety of supersymmetry scenarios.


title: Ramifications of intranuclear re-scattering in MINOS

abstract:
  MINOS will measure the composition of a neutrino beam at two locations, 735km
apart, in an effort confirm the (atmospheric) neutrino oscillation hypothesis
and measure the associated mixing parameters. Oscillations will be manifested
as a difference in the rate and energy spectrum of muon neutrino CC
interactions measured in the two detectors. Because most interactions observed
in MINOS are inelastic, the neutrino energy is reconstructed as the sum of the
energy carried by the muon and that seen in the hadronic shower emanating from
the struck nucleus. The latter is sensitive to uncertainties in the
hadronisation process, chief among them those due to intranuclear re-scattering
(i.e., final state interactions). We discuss the simulation of intranuclear
re-scattering currently used by MINOS and its effect on quantities observable
in the experiment.


title: Kaon pair production close to threshold

abstract:
  The total cross section of the reaction pp->ppK+K- has been measured at
excess energies Q=10 MeV and 28 MeV with the magnetic spectrometer COSY-11. The
new data show a significant enhancement of the total cross section compared to
pure phase space expectations or calculations within a one boson exchange
model. In addition, we present invariant mass spectra of two particle
subsystems. While the K+K- system is rather constant for different invariant
masses, there is an enhancement in the pK- system towards lower masses which
could at least be partially connected to the influence of the Lambda(1405)
resonance.


title:
Observation of a near-threshold enhancement in the \omega\phi mass
  spectrum from the doubly OZI suppressed decay J/\psi \to \gamma \omega \phi

abstract:
  An enhancement near threshold is observed in the \omega \phi invariant mass
spectrum from the doubly OZI suppressed decays of J/\psi \to \gamma \omega
\phi, based on a sample of 5.8 X 10^7 J/\psi events collected with the BESII
detector. A partial wave analysis shows that this enhancement favors J^P = 0^+,
and its mass and width are M = 1812^{+19}_{-26} (stat) +- 18 (syst) MeV/c^2 and
\Gamma = 105+-20 (stat) +- 28$ (syst) MeV/c^2. The product branching fraction
is determined to be B(J/\psi\to \gamma X) B(X\to\omega\phi) = (2.61 +- 0.27
(stat) +- 0.65$ (syst)) X 10^{-4}.


title: Beauty and Charm Physics at HERA

abstract:
  The most recent beauty and charm results from the ZEUS and H1 collaborations
are presented.


title: Measurement of chi_cJ Decays to 2(pi^+pi^-)ppbar Final States

abstract:
  Using chi_cJ -> 2(\pi^+\pi^-) ppbar decays from 14 \times 10^6 psi(2S) events
accumulated by the BESII detector at the BEPC, the intermediate states
Xi^+Xi^-, Lambda Lambdabar pi^+ pi^-, and K_SK_S p pbar are studied, and their
branching ratios or upper limits are measured.


title: Charmonium Decays of $Y(4260), psi(4160), and psi(4040)

abstract:
  Using data collected with the CLEO detector operating at the CESR e+e-
collider at sqrt s = 3.97-4.26 GeV, we investigate 15 charmonium decay modes of
the psi(4040), psi(4160), and Y(4260) resonances. We confirm, at 11$\sigma$
significance, the BaBar Y(4260) --> pi+ pi- J/psi discovery, make the first
observation of Y(4260) --> pi0 pi0 J/psi (5.1 sigma), and find the first
evidence for Y(4260) --> K+ K- J/psi (3.7 sigma). We measure e+e-
cross-sections at sqrt s = 4.26 GeV as sigma(pi+ pi- J/psi) = 58 +12-10 +- 4
pb, sigma(pi0 pi0 J/psi) = 23 +12 -8 +- 1 pb, and sigma(K+ K- J/psi) = 9 +9 -5
+- 1 pb, in which the uncertainties are statistical and systematic,
respectively. Upper limits are placed on other decay rates from all three
resonances.


title:
Final Report of the Muon E821 Anomalous Magnetic Moment Measurement at
  BNL

abstract:
  We present the final report from a series of precision measurements of the
muon anomalous magnetic moment, a_mu = (g-2)/2. The details of the experimental
method, apparatus, data taking, and analysis are summarized. Data obtained at
Brookhaven National Laboratory, using nearly equal samples of positive and
negative muons, were used to deduce a_mu(Expt) = 11 659 208.0(5.4)(3.3) x
10^-10, where the statistical and systematic uncertainties are given,
respectively. The combined uncertainty of 0.54 ppm represents a 14-fold
improvement compared to previous measurements at CERN. The standard model value
for a_mu includes contributions from virtual QED, weak, and hadronic processes.
While the QED processes account for most of the anomaly, the largest
theoretical uncertainty, ~0.55 ppm, is associated with first-order hadronic
vacuum polarization. Present standard model evaluations, based on e+e- hadronic
cross sections, lie 2.2 - 2.7 standard deviations below the experimental
result.


title: Rare Particle Searches with the high altitude SLIM experiment

abstract:
  The search for rare particles in the cosmic radiation remains one of the main
aims of non-accelerator particle astrophysics. Experiments at high altitude
allow lower mass thresholds with respect to detectors at sea level or
underground. The SLIM experiment is a large array of nuclear track detectors
located at the Chacaltaya High Altitude Laboratory (5290 m a.s.l.). The
preliminary results from the analysis of a part of the first 236 sq.m exposed
for more than 3.6 y are here reported. The detector is sensitive to
Intermediate Mass Magnetic Monopoles and to SQM nuggets and Q-balls, which are
possible Dark Matter candidates.


title: Double beta decay experiments

abstract:
  The present status of double beta decay experiments are reviewed. The results
of the most sensitive experiments, NEMO-3 and CUORICINO, are discussed.
Proposals for future double beta decay experiments are considered. In these
experiments sensitivity for the effective neutrino mass will be on the level of
(0.1-0.01) eV.


title: Searches for Scalar Top and Bottom Quarks at the Tevatron

abstract:
  Searches for the supersymmetric partners of top and bottom quarks using data
up to 340 pb$^{-1}$ taken at the Tevatron $p\bar{p}$ collider are described. We
report on searches for scalar top quarks $\tilde{t}$ in the decays
$\tilde{t}\to c \tilde{\chi}_1^0$ and $\tilde{t}\to bl\tilde{\nu}$ and for
scalar bottom quarks $\tilde{b}$ in the decay $\tilde{b}\to b
\tilde{\chi}_1^0$. No evidence for a signal has been found, but improved
exclusion regions have been derived in the framework of a generic minimal
superymmetric extension of the standard model.


title: A Search for Charged Massive Stable Particles

abstract:
  A search for charged massive (quasi-) stable particles with the D0 detector
at the Tevatron collider based on 390 pb^{-1} of data is presented. The search
is performed in the frameworks of gauge-mediated supersymmetry breaking and the
minimal supersymmetric extentension of the standard model. The hypothetical
particles are assumed to be pair-produced in p-anti-p collisions giving a
signature of two reconstructed muon-like objects with high invariant mass and
time-of-flights indicative of heavy particles. Since no excess over background
is observed, cross-section limits for the pair-production of stable staus and
charginos are set. Mass limits of 140 GeV for a higgsino-like chargino and 174
GeV for a gaugino-like chargino are set.


title: Theoretical and Experimental Status of Magnetic Monopoles

abstract:
  The Tevatron has inspired new interest in the subject of magnetic monopoles.
First there was the 1998 D0 limit on the virtual production of monopoles, based
on the theory of Ginzburg and collaborators. In 2000 and 2004 results from an
experiment (Fermilab E882) searching for real magnetically charged particles
bound to elements from the CDF and D0 detectors were reported. The strongest
direct experimental limits, from the CDF collaboration, have been reported in
2005. Less strong, but complementary, limits from the H1 collaboration at HERA
were reported in the same year. Interpretation of these experiments also
require new developments in theory. Earlier experimental and observational
constraints on point-like (Dirac) and non-Abelian monopoles were given from the
1970s through the 1990s, with occasional short-lived positive evidence for such
exotic particles reported. The status of the experimental limits on monopole
masses will be reported, as well as the limitation of the theory of magnetic
charge at present.


title: Search for RPV Gaugino and Gravitino Production at HERA

abstract:
  In R-parity violating supersymmetry a gaugino can be produced at HERA by the
t-channel exchange of a selectron between the beam positron or electron and an
initial quark from the beam proton. In the generic MSSM model the gaugino can
decay in a cascade into two quarks and an (anti)lepton. For this model a search
in the e^{+-}-channel has been performed with the ZEUS detector using combined
e^{+-}p-data of L_{int}=121pb^{-1}. No deviations from the Standard Model have
been observed and exclusion limits on parameters of the MSSM have been set.
Assuming the GMSB model with the gravitino as lightest supersymmetric particle
and the neutralino as next-to-lightest supersymmetric particle, the neutralino
decays into a gravitino and a high-energy photon. For this model searches have
been performed with the H1 detector using e^+p-data of L_{int}=64.3pb^{-1} and
e^-p-data of L_{int}=13.5pb^{-1} and with the ZEUS detector using e^+p-data of
L_{int}=65.1pb^{-1}. No deviations from the Standard Model have been observed
and limits on the selectron and neutralino masses have been set. Additionally,
limits on the R-parity violating Yukawa coupling have been derived in the
search performed with the H1 detector.


title: Search for Neutral MSSM Higgs Bosons at LEP

abstract:
  The four LEP collaborations, ALEPH, DELPHI, L3 and OPAL, have searched for
the neutral Higgs bosons which are predicted by the Minimal Supersymmetric
Standard Model (MSSM). The data of the four collaborations are statistically
combined and examined for their consistency with the background hypothesis and
with a possible Higgs boson signal. The combined LEP data show no significant
excess of events which would indicate the production of Higgs bosons. The
search results are used to set upper bounds on the cross-sections of various
Higgs-like event topologies. The results are interpreted within the MSSM in a
number of "benchmark" models, including CP-conserving and CP-violating
scenarios. These interpretations lead in all cases to large exclusions in the
MSSM parameter space. Absolute limits are set on the parameter tanb and, in
some scenarios, on the masses of neutral Higgs bosons.


title: Time-Domain Measurement of Broadband Coherent Cherenkov Radiation

abstract:
  We report on further analysis of coherent microwave Cherenkov impulses
emitted via the Askaryan mechanism from high-energy electromagnetic showers
produced at the Stanford Linear Accelerator Center (SLAC). In this report, the
time-domain based analysis of the measurements made with a broadband (nominally
1-18 GHz) log periodic dipole array antenna is described. The theory of a
transmit-receive antenna system based on time-dependent effective height
operator is summarized and applied to fully characterize the measurement
antenna system and to reconstruct the electric field induced via the Askaryan
process. The observed radiation intensity and phase as functions of frequency
were found to agree with expectations from 0.75-11.5 GHz within experimental
errors on the normalized electric field magnitude and the relative phase; 0.039
microV/MHz/TeV and 17 deg, respectively. This is the first time this agreement
has been observed over such a broad bandwidth, and the first measurement of the
relative phase variation of an Askaryan pulse. The importance of validation of
the Askaryan mechanism is significant since it is viewed as the most promising
way to detect cosmogenic neutrino fluxes at E > 10^15 eV.


title: Tau lepton physics at LEP

abstract:
  The talk covers three contributions on (i) the final measurement of branching
ratios and spectral functions of t decays using the full LEP-I data from ALEPH,
(ii) a preliminary measurement of the t hadronic branching ratios from DELPHI
and (iii) a measurement of the strange spectral function in hadronic t decays
from OPAL. These measurements are discussed and the relevant physics topics are
briefly reviewed.


title: Search for Z'--> e^+e^- Using Dielectron Mass and Angular Distribution

abstract:
  We search for Z' bosons in dielectron events produced in ppbar collisions at
sqrt{s}=1.96 TeV, using a 0.45 fb^(-1) dataset accumulated with the CDF II
detector at the Fermilab Tevatron. To identify the Z' --> e^+e^- signal, both
the dielectron invariant mass distribution and the angular distribution of the
electron pair are used. No evidence of a signal is found, and 95% confidence
level lower limits are set on the Z' mass for several models. Limits are also
placed on the mass and gauge coupling of a generic Z', as well as on the
contact interaction mass scales for different helicity structure scenarios.


title: Search for CP Violating neutral Higgs bosons in the MSSM at LEP

abstract:
  The LEP collaborations ALEPH, DELPHI, L3 and OPAL have searched for the
neutral Higgs bosons which are predicted within the framework of the Minimal
Supersymmetric Standard Model (MSSM). The data of the four collaborations are
statistically combined and show no signicant excess of events which would
indicate the production of Higgs bosons. The search results are thus used to
set upper bounds on the cross sections of various Higgs-like event topologies
and limits on MSSM benchmark models, including CP-conserving and CP-violating
scenarios. Here, the limits on the model parameters of the CP-violating
benchmark scenario CPX and derivates of this scenario are shown.


title:
An experiment for the measurement of the bound-beta decay of the free
  neutron

abstract:
  The hyperfine-state population of hydrogen after the bound-beta decay of the
neutron directly yields the neutrino left-handedness or a possible right-handed
admixture and possible small scalar and tensor contributions to the weak force.
Using the through-going beam tube of a high-flux reactor, a background free
hydrogen rate of ca. 3 s$^{-1}$ can be obtained. The detection of the neutral
hydrogen atoms and the analysis of the hyperfine states is accomplished by Lamb
shift source type quenching and subsequent ionization. The constraints on the
neutrino helicity and the scalar and tensor coupling constants of weak
interaction can be improved by a factor of ten.


title: Search for a new Resonance decaying into Top-Antitop at Tevatron

abstract:
  In this report a new search for a narrow-width heavy resonance decaying into
top quark pairs (X -> ttbar) in ppbar collisions at sqrt(s)=1.96 TeV has been
performed using data collected by the D0 detector at the Fermilab Tevatron
collider. The analysis considers ttbar candidate events in the lepton+jets
channel using a lifetime tag to identify b-jets and the ttbar invariant mass
distribution to search for evidence of resonant production. The analyzed
dataset corresponds to an integrated luminosity of approximately 370 pb^-1.
Since no evidence for a ttbar resonance X is found, upper limits on sigma(X) x
B(X -> ttbar) for different hypothesized resonance masses using a Bayesian
approach are set. Within a topcolor-assisted technicolor model, the existence
of a leptophobic Z' boson with M(Z') < 680 GeV and width Gamma(Z') = 0.012
M(Z') can be excluded at 95% C.L..


title:
Measurement of time-dependent CP asymmetries in B0->D(*)+-pi-+ and
  B0->D+-rho-+ decays

abstract:
  We present updated results on time-dependent CP asymmetries in fully
reconstructed B0->D(*)+-pi-+ and B0->D+-rho-+ decays in approximately 232
million Y(4S)->BBbar events collected with the BaBar detector at the PEP-II
asymmetric-energy B factory at SLAC.
  From a time-dependent maximum likelihood fit we obtain for the parameters
related to the CP violation angle 2beta+gamma: a^{D\pi} = -0.010 +/- 0.023 +/-
0.007, c_{\rm lep}^{D\pi} = -0.033 +/- 0.042 +/- 0.012, a^{D^*\pi} = -0.040 +/-
0.023 +/- 0.010, c_{\rm lep}^{D^*\pi} = 0.049 +/- 0.042 +/- 0.015, a^{D\rho} =
-0.024 +/- 0.031 +/- 0.009, c_{\rm lep}^{D\rho} = -0.098 +/- 0.055 +/- 0.018,
where the first error is statistical and the second is systematic. Using other
measurements and theoretical assumptions, we interpret the results in terms of
the angles of the Cabibbo-Kobayashi-Maskawa unitarity triangle and find
|sin(2beta+gamma)| > 0.64 (0.40) at 68% (90%) confidence level.


title: Charged Current Single Pion Cross Section Measurement at MiniBooNE

abstract:
  We present MiniBooNE's preliminary numu charged-current single pion (CC1pi)
cross section measurement, calculated using the ratio to charge current
quasi-elastic (CCQE) events. We find the inclusive CC1pi cross section to be
below the predcition of the NUANCE and NEUGEN Monte Carlos.


title: Prospects for Antineutrino Running at MiniBooNE

abstract:
  MiniBooNE began running in antineutrino mode on 19 January, 2006. We describe
the sensitivity of MiniBooNE to LSND-like nuebar oscillations and outline a
program of antineutrino cross-section measurements necessary for the next
generation of neutrino oscillation experiments. We describe three independent
methods of constraining wrong-sign (neutrino) backgrounds in an antineutrino
beam, and their application to the MiniBooNE antineutrino analyses.


title: Evidence for B-> eta' pi and improved measurements for B-> eta' K

abstract:
  We report evidence for exclusive two-body charmless hadronic B meson decays
B-> eta' pi, and improved measurements of B-> eta' K. The results are obtained
from a data sample of 386 x 10^6 BBbar pairs collected at the Upsilon(4S)
resonance, with the Belle detector at the KEKB asymmetric energy e+e- collider.
We measure BF(B-> eta' pi+)=[ 1.76 +0.67-0.62(stat) +0.15-0.14(syst)] x 10^-6
and BF(B-> eta' pi0)=[ 2.79 +1.02-0.96(stat) +0.25-0.34(syst)] x 10^-6. We also
report the ratio of BF(B-> eta' K+) / BF(B-> eta' K0) = 1.17 +-0.08(stat)
+-0.03(syst) and direct CP asymmetries for the charged modes.


title: Measurement of B(t->Wb)/B(t->Wq) at sqrt(s) = 1.96 TeV

abstract:
  We present the measurement of R = B(t->Wb)/B(t->Wq) in ppbar collisions at
sqrt(s) = 1.96 TeV, using 230 pb-1 of data collected by the DO experiment at
the Fermilab Tevatron Collider. We fit simultaneously R and the number of
selected top quark pairs (ttbar), to the number of identified b-quark jets in
events with one electron or one muon, three or more jets, and high transverse
energy imbalance. To improve sensitivity, kinematical properties of events with
no identified b-quark jets are included in the fit. We measure R = 1.03 +0.19
-0.17 (stat+syst), in good agreement with the standard model. We set lower
limits of R > 0.61 and |V_tb| > 0.78 at 95% confidence level.


title: Averages of b-hadron Properties at the End of 2005

abstract:
  This article reports world averages for measurements on b-hadron properties
obtained by the Heavy Flavor Averaging Group (HFAG) using the available results
as of at the end of 2005. In the averaging, the input parameters used in the
various analyses are adjusted (rescaled) to common values, and all known
correlations are taken into account. The averages include lifetimes, neutral
meson mixing parameters, parameters of semileptonic decays, branching fractions
of B meson decays to final states with open charm, charmonium and no charm, and
measurements related to CP asymmetries.


title:
Improved search for $\nu_\mu \to \nu_e$ oscillation in a long-baseline
  accelerator experiment

abstract:
  We performed an improved search for $\nu_\mu \to \nu_e$ oscillation with the
KEK to Kamioka (K2K) long-baseline neutrino oscillation experiment, using the
full data sample of $9.2 \times 10^{19}$\xspace protons on target. No evidence
for a $\nu_e$ appearance signal was found, and we set bounds on the $\nu_\mu
\to \nu_e$ oscillation parameters. At $\Delta m^2$ = $2.8 \times 10^{-3}
\mathrm{eV}^2$, the best fit value of the K2K $\nu_\mu$ disappearance analysis,
we set an upper limit of $\sin^2 2\theta_{\mu e}$ $<$ 0.13 at 90% confidence
level.


title: Prospects to search for E6 isosinglet quarks in ATLAS

abstract:
  We consider pair production of new down-type isosinglet quarks originating
from E_{6}, which is the favorite gauge symmetry group in superstring inspired
GUT models. The study concentrates on the possibility of observing the pair
production of the lightest of the new quarks, D, in the ATLAS detector at the
forthcoming LHC accelerator, in the channel D\bar{D}\to ZjZj . Both signal and
background events are studied using tree level event generators based on Monte
Carlo techniques. The detector effects are taken into account using the ATLAS
fast simulation tool, ATLFAST. It is shown that ATLAS can observe the D quark
within the first year of low luminosity LHC operation if its mass is less than
650 GeV. For the case of two years of full luminosity running, 1 TeV can be
reached with about three sigma significance.


title:
Search for High-Mass Resonances Decaying to e-mu in ppbar Collisions at
  sqrt(s)=1.96 TeV

abstract:
  We describe a general search for resonances decaying to a neutral e-mu final
state in ppbar collisions at a center-of-mass energy of 1.96 TeV. Using a data
sample representing 344 pb^-1 of integrated luminosity recorded by the CDF-II
experiment, we compare Standard Model predictions with the number of observed
events for invariant masses between 50 and 800 GeV/c^2. Finding no significant
excess (5 events observed vs. 7.7 +/- 0.8 expected for e-mu invariant masses >
100 GeV/c^2), we set limits on sneutrino and Z' masses as functions of lepton
family number violating couplings.


title: Top Quark Current Experimental Status

abstract:
  Ten years after its discovery at the Tevatron collider, we still know little
about the top quark. Its large mass suggests it may play a key role in the
mechanism of Electroweak Symmetry Breaking (EWSB), or open a window of
sensitivity to new physics related to EWSB and preferentially coupled to it. To
determine whether this is the case, precision measurements of top quark
properties are necessary. The high statistics samples being collected by the
Tevatron experiments during Run II start to incisively probe the top quark
sector. This report summarizes the experimental status of the top quark,
focusing in particular on the recent measurements from the Tevatron.


title: Data production of a large Linux PC Farm for the CDF experiment

abstract:
  The data production farm for the CDF experiment is designed and constructed
to meet the needs of the Run II data collection at a maximum rate of 20
MByte/sec during the run. The system is composed of a large cluster of personal
computers (PCs) with a high-speed network interconnect and a custom design
control system for the flow of data and the scheduling of tasks on this PC
farm. The farm explores and exploits advances in computing and communication
technology. The data processing has achieved a stable production rate of
approximately 2 TByte per day. The software and hardware of the CDF production
farms has been successful in providing large computing and data throughput
capacity to the experiment.


title:
Experimental study of quasi-elastic neutrino interactions on Ar with a
  liquid Ar TPC exposed to the WANF neutrino beam

abstract:
  We present results from the first exposure of a liquid Ar time projection
chamber to a neutrino beam. The data have been collected in 1997 with a 50
liter ICARUS-like chamber located between the CHORUS and NOMAD experiment at
the CERN West Area Neutrino Facility. We focus on the analysis of quasi-elastic
interactions; despite the limited size of the detector, nuclear effects beyond
Fermi motion and Pauli blocking have been observed as perturbations to the pure
quasi-elastic kinematics.


title: Physics Benchmarks for the ILC Detectors

abstract:
  This note presents a list of physics processes for benchmarking the
performance of proposed ILC detectors. This list gives broad coverage of the
required physics capabilities of the ILC experiments and suggests target
accuracies to be achieved. A reduced list of reactions, which capture within a
very economical set the main challenges put by the ILC physics program, is
suggested for the early stage of benchmarking of the detector concepts.


title: Tests of Quantum Chromo Dynamics at e^+e^- Colliders

abstract:
  The current status of tests of the theory of strong interactions, Quantum
Chromo Dynamics (QCD), with data from hadron production in e^+e^- annihilation
experiments is reviewed. The LEP experiments ALEPH, DELPHI, L3 and OPAL have
published many analyses with data recorded on the Z^0 resonance at sqrt(s)=91.2
GeV and above up to sqrt(s)>200 GeV. There are also results from SLD at
sqrt(s)=91.2 GeV and from reanalysis of data recorded by the JADE experiment at
14<sqrt(s)<44 GeV. The results of studies of jet and event shape observables,
of particle production and of quark gluon jet differences are compared with
predictions by perturbative QCD calculations. Determinations of the strong
coupling constant alpha_S(M_Z) from jet and event shape observables, scaling
violation and fragmentation functions, inclusive observables from Z^0 decays,
hadronic tau decays and hadron production in low energy e^+e^- annihilation are
discussed. Updates of the measurements are performed where new data or improved
calculations have become available. Finally, investigations of the gauge
structure of QCD are summarised.


title:
Measurements of the Branching Fraction and Time-Dependent CP Asymmetries
  of B0 to J/Psi Pi0 decays

abstract:
  We present measurements of the branching fraction and time-dependent CP
asymmetries in B0 -> JPsi pi0 decays based on (231.8 +/- 2.6) x 10**6
asymmetries Y(4S) -> BBbar decays collected with the BaBar detector at the SLAC
PEP-II asymmetric-energy B factory. We obtain a branching fraction B(B0 -> JPsi
pi0) = (1.94 +/- 0.22 (stat.) +/- 0.17 (syst.)) x 10**-5. We also measure the
CP asymmetry parameters C = -0.21 +/- 0.26 (stat.) +/- 0.06 (syst.) and S =
-0.68 +/- 0.30 (stat.) +/- 0.04 (syst.).


title:
Branching Fraction Limits for B0 Decays to eta' eta, eta' pi0 and eta
  pi0

abstract:
  We describe searches for decays to two-body charmless final states eta' eta,
eta' pi0 and eta pi0 of B0 mesons produced in e+e- annihilation. The data,
collected with the BaBar detector at the Stanford Linear Accelerator Center,
represent 232 million produced B-anti-B pairs. The results for branching
fractions are, in units of 10^-6 (upper limits at 90% C.L.): BF(B0 -> eta' eta)
= 0.2 +0.7 -0.5 +/- 0.4 (<1.7), BF(B0 -> eta pi0) = 0.6 +0.5 -0.4 +/- 0.1
(<1.3), and BF(B0 -> eta' pi0) = 0.8 +0.8 -0.6 +/- 0.1 (<2.1). The first error
quoted is statistical and the second systematic.


title: Photoproduction of Dijets with High Transverse Momenta at HERA

abstract:
  Differential dijet cross sections are measured in photoproduction in the
region of photon virtualities Q^2 < 1 GeV^2 with the H1 detector at the HERA ep
collider using an integrated luminosity of 66.6 pb^{-1}. Jets are defined with
the inclusive k_T algorithm and a minimum transverse momentum of the leading
jet of 25 GeV is required. Dijet cross sections are measured in direct and
resolved photon enhanced regions separately. Longitudinal proton momentum
fractions up to 0.7 are reached. The data compare well with predictions from
Monte Carlo event generators based on leading order QCD and parton showers and
with next-to-leading order QCD calculations corrected for hadronisation
effects.


title:
Measurement of the Upsilon Production Cross Section in 920 GeV
  Fixed-Target Proton-Nucleus Collisions

abstract:
  The proton-nucleon cross section ratio $R=Br(\Upsilon\to l^+l^-)
d\sigma(\Upsilon)/dy|_{y=0} / {\sigma(J/\psi)}$ has been measured with the
HERA-B spectrometer in fixed-target proton-nucleus collisions at 920 GeV proton
beam energy corresponding to a proton-nucleon cms energy of sqrt{s}=41.6 GeV.
  The combined results for the Upsilon decay channels Upsilon $\to e^+e^-$ and
Upsilon $\to\mu^+\mu^-$ yield a ratio $R=(9.0 \pm 2.1) 10^{-6}$. The
corresponding Upsilon production cross section per nucleon at mid-rapidity
(y=0) has been determined to be $Br(\Upsilon\to{}l^+l^-)
{d\sigma(\Upsilon)/dy}|_{y=0}= 4.5 \pm 1.1 $ pb/nucleon.


title: Deep Inelastic Electron-Nucleon Scattering at the LHC

abstract:
  The physics, and a design, of a Large Hadron Electron Collider (LHeC) are
sketched. With high luminosity, 10^{33}cm^{-2}s^{-1}, and high energy,
\sqrt{s}=1.4 TeV, such a collider can be built in which a 70 GeV electron
(positron) beam in the LHC tunnel is in collision with one of the LHC hadron
beams and which operates simultaneously with the LHC. The LHeC makes possible
deep-inelastic lepton-hadron (ep, eD and eA) scattering for momentum transfers
Q^2 beyond 10^6 GeV^2 and for Bjorken x down to the 10^{-6}. New sensitivity to
the existence of new states of matter, primarily in the lepton-quark sector and
in dense partonic systems, is achieved. The precision possible with an
electron-hadron experiment brings in addition crucial accuracy in the
determination of hadron structure, as described in Quantum Chromodynamics, and
of parton dynamics at the TeV energy scale. The LHeC thus complements the
proton-proton and ion programmes, adds substantial new discovery potential to
them, and is important for a full understanding of physics in the LHC energy
range.


title:
Further evidence for formation of a narrow baryon resonance with
  positive strangeness in K+ collisions with Xe nuclei

abstract:
  We have continued our investigation of the charge-exchange reaction K^+ Xe
--> K^0 p Xe' in the bubble chamber DIANA. In agreement with our previous
results based on part of the present statistics, formation of a narrow p K^0
resonance with mass of 1537+-2 MeV/c^2 is observed in the elementary transition
K^+ n --> K^0 p on a neutron bound in the Xenon nucleus. Visible width of the
peak is consistent with being entirely due to instrumental resolution and
allows to place an upper limit on its intrinsic width: \Gamma < 9 MeV/c^2. A
more precise estimate of the resonance intrinsic width, \Gamma = 0.36+-0.11
MeV/c^2, is obtained from the ratio between the numbers of resonant and
non-resonant charge-exchange events. The signal is observed in a restricted
interval of incident K^+ momentum, that is consistent with smearing of a narrow
p K^0 resonance by Fermi motion of the target neutron. Statistical significance
of the signal is some 7.3, 5.3, and 4.3 standard deviations for the estimators
S/sqrt{B}, S/sqrt{S+B}, and S/sqrt{S+2B}, respectively. This observation
confirms and reinforces our earlier results, and offers strong evidence for
formation of a pentaquark baryon with positive strangeness in the
charge-exchange reaction K^+ n --> K^0 p on a bound neutron.


title:
Measurement of Forward-Backward Asymmetry and Wilson Coefficients in $B
  \to K^* \ell^+ \ell^-$

abstract:
  We report the first measurement of the forward-backward asymmetry and the
ratios of Wilson coefficients $A_9/A_7$ and $A_{10}/A_7$ in $B \to K^* \ell^+
\ell^-$, where $\ell$ represents an electron or a muon. We observe a large
integrated forward-backward asymmetry with a significance of 3.4$\sigma$. The
results are obtained from a data sample containing 386 $\times 10^6$ $B\bar{B}$
pairs that were collected on the $\Upsilon(4S)$ resonance with the Belle
detector at the KEKB asymmetric-energy $e^+ e^-$ collider.


title:
Exclusive baryon-antibaryon production in $\gamma\gamma$ collisions at
  e+e- colliders

abstract:
  The exclusive production of baryon-antibaryon pairs in the collisions of two
quasi-real photons has been studied using different detectors at e+e-
colliders. Results are presented for $\gamma\gamma\to$ proton antiproton,
$\gamma\gamma\to\Lambda\bar{\Lambda}$, and $\gamma\gamma\to
\Sigma^{0}\bar{\Sigma^{0}}$ final states. The cross-section measurements are
compared with all the existing experimental data and with the analytic
calculations based on the three-quark model, on the quark-diquark model, and on
the handbag model.


title:
Measurement of Interference between Electromagnetic and Strong
  Amplitudes in psi(2S) Decays to Two Pseudoscalar Mesons

abstract:
  Using a sample of 3.08 million psi(2S) decays collected at sqrt{s} = 3.686
GeV with the CLEO detector at the Cornell Electron Storage Ring, we have
measured the branching fractions for psi(2S) decays to pseudoscalar pairs
pi+pi-, K+K-, and KsKl. We obtain B(psi(2S) -> pi+pi-) < 2.1 x 10^{-5} (90%
C.L.), B(psi(2S) -> K+K-) = (6.3 +- 0.6(stat) +- 0.3(syst)) x 10^{-5}, and
B(psi(2S) -> KsKl) = (5.8 +- 0.8(stat) +- 0.4(syst)) x 10^{-5}. The branching
fractions allow extraction of the relative phase Delta = (95 +- 15) degrees and
strength ratio R = (2.5 +- 0.4) of the three-gluon and one-photon amplitudes
for these modes.


title:
Measurement of the Pion Form Factor in the Energy Range 1.04-1.38 GeV
  with the CMD-2 Detector

abstract:
  The cross section for the process $e^+e^-\to\pi^+\pi^-$ is measured in the
c.m. energy range 1.04-1.38 GeV from 995 000 selected collinear events
including 860000 $e^+e^-$ events, 82000 $\mu^+\mu^-$ events, and 33000
$\pi^+\pi^-$ events. The systematic and statistical errors of measuring the
pion form factor are equal to 1.2-4.2 and 5-13%, respectively.


title:
Measurement of Hadron and Lepton-Pair Production in e+e- Collisions at
  sqrt{s}=192-208GeV at LEP

abstract:
  Hadron production and lepton-pair production in e+e- collisions are studied
with data collected with the L3 detector at LEP at centre-of-mass energies
sqrt{s}=192-208GeV. Using a total integrated luminosity of 453/pb, 36057
hadronic events and 12863 lepton-pair events are selected. The cross sections
for hadron production and lepton-pair production are measured for the full
sample and for events where no high-energy initial-state-radiation photon is
emitted prior to the collisions. Lepton-pair events are further investigated
and forward-backward asymmetries are measured. Finally, the differential cross
sections for electron-positron pair-production is determined as a function of
the scattering angle. An overall good agreement is found with Standard Model
predictions.


title:
Reconclining phi radiative decays with other data for a0(980), fo(980),
  pi-pi -> KK and pi-pi -> eta-eta

abstract:
  Data for phi -> gamma (eta-pizero) are analysed using the KK loop model and
compared with parameters of a0(980) derived from Crystal Barrel data. The
eta-pi mass spectrum agrees closely and the absolute normalisation lies just
within errors. However, BES parameters for fo(980) predict a normalisation for
phi -> gamma (pizero-pizero) at least a factor 2 lower than is observed. This
discrepancy may be eliminated by including constructive interference between
fo(980) and sigma. The magnitude required for sigma -> KK is consistent with
data on pi-pi -> KK. A dispersion relation analysis by Buttiker, Descotes-Genon
and Moussallam of pi-pi -> KK leads to a similar conclusion. Data on pi-pi ->
eta-eta also require decays of sigma to eta-eta. Four sets of pi-pi -> KK data
all require a small but definite fo(1370) signal.


title: Determining the upper limit of Gamma_{ee} for the Y(4260)

abstract:
  By fitting the R values between 3.7 and 5.0 GeV measured by the BES
collaboration, the upper limit of the electron width of the newly discovered
resonance Y(4260) is determined to be 580 eV at 90% C.L. Together with the
BABAR measurement on the product of Gamma_{ee} and BR(Y(4260) --> pi+pi-
J/psi), this implies a large decay width of Y(4260) --> pi+pi- J/psi final
states.


title: Particle production at HERA

abstract:
  Recent results on the properties of the hadronic final state at the HERA
collider are presented. Strangeness production and correlations have been
studied in the laboratory system for deep inelastic scattering (DIS). Inclusive
$K^0_S$, $\Lambda$ and $\bar{\Lambda}$ production has been measured and
compared to Monte Carlo model calculations. No significant $\Lambda$ to
$\bar{\Lambda}$ production asymmetry was observed and the measured $\Lambda
(\bar{\Lambda})$ polarisations are consistent with zero. Bose-Einstein
correlations between charged and neutral kaons have been studied and the
obtained results are compared with the LEP measurements. A search for heavy
particles was performed in the photoproduction process. The cross section for
anti-deuteron production has been measured at a mean center-of-mass energy of
$W_{\gamma p}$ = 200 GeV. The azimuthal angle distribution of hadrons in DIS
has also been studied in the hadronic center-of-mass system. The measurements
of the azimuthal asymmetry are consistent with the perturbative QCD
predictions.


title: Search for the non-D\barD Decay psi(3770) --> K_S^0 K_L^0

abstract:
  Using the current world's largest data sample of psi(3770) decays, we present
results of a search for the non-DDbar decay psi(3770) -> KsKl. We find no
signal, and obtain an upper limit of Sigma(psi(3770) -> KsKl) < 0.07 pb at 90%
confidence level (CL). Our result tests a theoretical prediction for the upper
bound on B(psi(3770) -> KsKl) based on a charmonia-mixing model.


title: Measurement of the B_c Meson Lifetime Using B_c ->J/Psi e nu

abstract:
  We present a measurement of the B_c+ meson lifetime in the semileptonic decay
mode Bc+ ->J/Psi e+ nu using the CDF II detector at the Fermilab Tevatron
Collider. From a sample of about 360pb-1 p-pbar collisions at sqrt(s)=1.96TeV,
we reconstruct J/Psi e+ pairs with invariant mass in the kinematically allowed
range 4<M(J/Psi e)<6GeV/c^2. A fit to the decay-length distribution of 238
signal events yields a measured Bc mesion lifetime 0.463 (+0.073,-0.065)+-0.036
ps.


title:
Search for the $\Theta^+$ pentaquark in the reaction $\gamma d \to p K^-
  K^+ n$

abstract:
  A search for the \thp in the reaction $\gamma d \to pK^-K^+n$ was completed
using the CLAS detector at Jefferson Lab. A study of the same reaction,
published earlier, reported the observation of a narrow \thp resonance. The
present experiment, with more than 30 times the integrated luminosity of our
earlier measurement, does not show any evidence for a narrow pentaquark
resonance. The angle-integrated upper limit on \thp production in the mass
range of 1.52 to 1.56 GeV/c$^2$ for the $\gamma d \to pK^-\Theta^+$ reaction is
0.3 nb (95% CL). This upper limit depends on assumptions made for the mass and
angular distribution of \thp production. Using \lamstar production as an
empirical measure of rescattering in the deuteron, the cross section upper
limit for the elementary $\gamma n \to K^-\Theta^+$ reaction is estimated to be
a factor of 10 higher, {\it i.e.}, $\sim 3$ nb (95% CL).


title: Direct Limits on the Bs Oscillation Frequency

abstract:
  We report results of a study of the Bs oscillation frequency using a large
sample of Bs semileptonic decays corresponding to approximately 1 fb-1 of
integrated luminosity collected by the D0 experiment at the Fermilab Tevatron
Collider in 2002-2006. The amplitude method gives a lower limit on the Bs
oscillation frequency at 14.8 ps-1 at the 95% C.L. At \Delta m_s = 19 ps-1, the
amplitude deviates from the hypothesis A=0 (A=1) by 2.5 (1.6) standard
deviations, corresponding to a two-sided C.L. of 1% (10%). A likelihood scan
over the oscillation frequency, \Delta m_s, gives a most probable value of 19
ps-1 and a range of 17 < \Delta m_s < 21 ps-1 at the 90% C.L., assuming
Gaussian uncertainties. This is the first direct two-sided bound measured by a
single experiment. If \Delta m_s lies above 22 ps-1, then the probability that
it would produce a likelihood minimum similar to the one observed in the
interval 16 < \Delta m_s < 22 ps-1 is (5.0+-0.3)%.


title: Measurements of Absolute Hadronic Branching Fractions of D Mesons

abstract:
  Using e+e- collisions recorded at the psi(3770) resonance with the CLEO-c
detector at the Cornell Electron Storage Ring, we determine absolute hadronic
branching fractions of charged and neutral D mesons. Among measurements for
both Cabibbo-favored and Cabibbo-suppressed modes, we obtain reference
branching fractions B(D0 -> K-pi+)=(3.91 +- 0.08 +- 0.09)% and B(D+ ->
K-pi+pi+)=(9.5 +- 0.2 +- 0.3)%, where the uncertainties are statistical and
systematic, respectively. Using a determination of the integrated luminosity,
we also extract the e+e- -> DDbar cross sections.


title: D0D0bar Quantum Correlations, Mixing, and Strong Phases

abstract:
  Due to the presence of the quantum correlation between the pair-produced D0
and D0bar from the decay of the psi(3770), the time-integrated single and
double tag decay rates depend on charm mixing amplitudes,
doubly-Cabibbo-suppressed amplitudes, and the relative strong phase, delta,
between D0 and D0bar decays to identical final states. Using 281 pb^-1 of
integrated luminosity collected with the CLEO-c detector on the psi(3770)
resonance, we measure the absolute branching fractions of D0 decays to K-pi+,
CP eigenstates, and semileptonic final states to determine cos(delta) for K-pi+
and to limit the mixing amplitude y.


title:
Search for the associated production of chargino and neutralino in the
  final state with three leptons

abstract:
  Supersymmetry, if realized in Nature, predicts the existence of new
particles, as chargino and neutralino, which might manifest themselves with
peculiar signatures. Three leptons and large missing transverse energy in the
event could signal their associated production. We report the latest results of
the search performed by the CDF Collaboration in proton-antiproton collisions
at Tevatron Run II.


title: Heavy Flavours and CP Violation

abstract:
  Recent results on Heavy Flavours and CP violation are presented. After a
short introduction a taste of K and D results is given. In a third part results
on Vtd and Vts are summaryzed including BBbar mixing results and Bd radiative
decays. A summary of Vcb and Vub measurements is presented in the fourth part.
In the next section CP violation measurements in the Bd sector are shown.
Finally in the last part the overall status of the determination of the CKM
matrix is presented both in the context of the Standard Model and in the
context of New Physics.


title:
Measurement of the quasi-elastic axial vector mass in neutrino-oxygen
  interactions

abstract:
  The weak nucleon axial-vector form factor for quasi-elastic interactions is
determined using neutrino interaction data from the K2K Scintillating Fiber
detector in the neutrino beam at KEK. More than 12,000 events are analyzed, of
which half are charged-current quasi-elastic interactions nu-mu n to mu- p
occurring primarily in oxygen nuclei. We use a relativistic Fermi gas model for
oxygen and assume the form factor is approximately a dipole with one parameter,
the axial vector mass M_A, and fit to the shape of the distribution of the
square of the momentum transfer from the nucleon to the nucleus. Our best fit
result for M_A = 1.20 \pm 0.12 GeV. Furthermore, this analysis includes updated
vector form factors from recent electron scattering experiments and a
discussion of the effects of the nucleon momentum on the shape of the fitted
distributions.


title:
Search for Large Extra Dimensions Using Dielectron and Diphoton Events
  in $p\bar{p}$ Collisions at $\sqrt{s}=1.8$ TeV

abstract:
  Arkani-Hamed, Dimopoulous, and Dvali have proposed a model of low-scale
quantum gravity featuring large extra dimensions. In this model, the exchange
of Kaluza-Klein towers of gravitons can enhance the production rate of electron
and photon pairs at high invariant mass in proton-antiproton collisions. The
amount of enhancement is characterized by the parameter $M_S$, the fundamental
Planck scale in the bulk extra dimensions. We have searched for this effect
using 100 pb$^{-1}$ of diphoton data and 110 pb$^{-1}$ of dielectron data
collected with the Collider Detector at Fermilab at $\sqrt{s}=1.8$ TeV during
the 1992-1996 run. In the absence of a signal, we place 95% confidence-level
limits on $M_S$ of 905 GeV/$c^2$ and 826 GeV/$c^2$, for the case of
constructive and destructive graviton interference respectively.


title: Search for neutrinoless decays tau -> lhh and tau -> lV0

abstract:
  We have searched for neutrinoless tau lepton decays into l h h or l V0, where
l stands for an electron or muon, h for a charged light hadron, pi or K, and V0
for a neutral vector meson, rho, K*(892) and phi, using a 158 /fb data sample
collected with the Belle detector at the KEKB e+e- collider. Since the number
of events observed are consistent with the expected background, we set upper
limits on the branching fractions in the range of 1.6-8.0 x 10-7 for various
decay modes at the 90% confidence level.


title: Proton Structure

abstract:
  Recent inclusive neutral current and charged current DIS data from
  HERA are discussed in context of pQCD and parton density functions.


title:
Diffractive Photoproduction of Rho Mesons with Large Momentum Transfer
  at HERA

abstract:
  The diffractive photoproduction of rho mesons, e p \to e rho Y, with large
momentum transfer squared at the proton vertex, |t|, is studied with the H1
detector at HERA using an integrated luminosity of 20.1 pb^{-1}. The
photon-proton centre of mass energy spans the range 75 < W < 95 GeV, the photon
virtuality is restricted to Q^2 < 0.01 GeV^2 and the mass M_Y of the proton
remnant is below 5 GeV. The t dependence of the cross section is measured for
the range 1.5 < |t| < 10.0 GeV^2 and is well described by a power law, dsigma/
d|t| \propto |t|^{-n}. The spin density matrix elements, which provide
information on the helicity structure of the interaction, are extracted using
measurements of angular distributions of the rho decay products. The data
indicate a violation of s-channel helicity conservation, with contributions
from both single and double helicity-flip being observed. The results are
compared to the predictions of perturbative QCD models.


title: Combination of CDF and D0 Results on the Mass of the Top Quark

abstract:
  We summarize the top-quark mass measurements from the CDF and D0 experiments
at Fermilab. We combine published Run-I (1992- 1996) measurements with the most
recent preliminary Run-II (2001- present) measurements using up to 750/pb of
data. Taking correlated uncertainties properly into account the resulting
preliminary world average mass of the top quark is Mt=172.5 +/- 1.3(stat) +/-
1.9(syst) GeV/c2, which corresponds to a total uncertainty of 2.3 GeV/c2. The
top-quark mass is now known with a precision of 1.3% - a 20% improvement
relative to the previous combination.
