title: Search for the Phi(1860) Pentaquark at COMPASS

abstract:
  Narrow Xi-pi+- and Xi-bar+pi+- resonances produced by quasi-real photons have
been searched for by the COMPASS experiment at CERN. The study was stimulated
by the recent observation of an exotic baryonic state decaying into Xi-pi-, at
a mass of 1862 MeV, interpreted as a pentaquark. While the ordinary hyperon
states Xi(1530)^0 and Xi-bar(1530)^0 are clearly seen, no exotic baryon is
observed in the data taken in 2002 and 2003.


title: Cold-Antimatter Physics

abstract:
  The CPT theorem and the Weak Equivalence Principle are foundational
principles on which the standard description of the fundamental interactions is
based. The validity of such basic principles should be tested using the largest
possible sample of physical systems. Cold neutral antimatter (low-energy
antihydrogen atoms) could be a tool for testing the CPT symmetry with high
precision and for a direct measurement of the gravitational acceleration of
antimatter. After several years of experimental efforts, the production of
low-energy antihydrogen through the recombination of antiprotons and positrons
is a well-established experimental reality. An overview of the ATHENA
experiment at CERN will be given and the main experimental results on
antihydrogen formation will be reviewed.


title:
Measurement of branching fractions and charge asymmetries in B+ decays
  to etapi+, etaK+, etarho+ and eta'pi+, and search for B0 decays to etaK0 and
  etaomega

abstract:
  We present measurements of branching fractions and charge asymmetries for six
B-meson decay modes with an eta or eta' meson in the final state. The data
sample corresponds to 232 million BBbar pairs collected with the BABAR detector
at the PEP-II asymmetric-energy e+e- B Factory at SLAC. We measure the
branching fractions (in units of 10^-6): B(B->etapi+)=5.1+/-0.6+/-0.3,
B(B->etaK+)=3.3+/-0.6+/-0.3, B(B->etaK0)=1.5+/-0.7+/-0.1 (<2.5 at 90% C.L.),
B(B->etarho+)=8.4+/-1.9+/-1.1, B(B->etaomega)=1.0+/-0.5+/-0.2 (<1.9 at 90%
C.L.), and B(B->eta'pi+)=4.0+/-0.8+/-0.4, where the first uncertainty is
statistical and second systematic. We also determine the charge asymmetries for
the charged modes: Ach(B->etapi+)=-0.13+/-0.12+/-0.01,
Ach(B->etaK+)=-0.20+/-0.15+/-0.01, Ach(B->etarho+)=0.02+/-0.18+/-0.02, and
Ach(B->eta'pi+)=0.14+/-0.16+/-0.01.


title: delta S = 2 nonleptonic hyperon decays

abstract:
  A sensitive search for the rare decays \Omega^- \to \Lambda \pi^- and \Xi^0
\to p \pi^- has been performed using data from the 1997 run of the HyperCP
(Fermilab E871) experiment. Limits on other such processes do not exclude the
possibility of observable rates for |\Delta S| = 2 nonleptonic hyperon decays,
provided the decays occur through parity-odd operators. We obtain the
branching-fraction limits B(\Omega^- \to \Lambda \pi^-)< 2.9 x 10^{-6} and
B(\Xi^0 \to p \pi^-)< 8.2 x 10^{-6}, both at 90% confidence level.


title: Search for B0 -> J/psi D0bar and B+ -> J/psi D0bar pi+ decays

abstract:
  We report the results of a search for the decay modes B0 -> J/psi D0bar and
B+ -> J/psi D0bar pi+. The analysis is based on 140 $\rm fb^{-1}$ of data
accumulated by the Belle detector at the KEKB asymmetric-energy $e^{+} e^{-}$
collider. No significant signals are observed and we determine the branching
fraction upper limits B(B0 -> J/psi D0bar) < 2.0 10^{-5} and B(B+ -> J/psi
D0bar pi+) < 2.5 10^{-5} at 90% confidence level. These results rule out the
explanation of the excess in the low momentum region of the inclusive J/psi
spectrum as intrinsic charm content in the B meson. The branching fractions of
the corresponding non-resonant decay channels are also reported.


title:
Measurement of Charm and Beauty Photoproduction at HERA using D* mu
  Correlations

abstract:
  A measurement of charm and beauty photoproduction at the electron proton
collider HERA is presented based on the simultaneous detection of a D*^{\pm}
meson and a muon. The correlation between the D* meson and the muon serves to
separate the charm and beauty contributions and the analysis provides
comparable sensitivity to both. The total and differential experimental cross
sections are compared to LO and NLO QCD calculations. The measured charm cross
section is in good agreement with QCD predictions including higher order
effects while the beauty cross section is higher.


title:
Search for Higgs Bosons Decaying into b anti-b and Produced in
  Association with a Vector Boson in Proton-Antiproton Collisions at 1.8 TeV

abstract:
  We present a new search for $H^{0}V$ production, where $H^0$ is a scalar
Higgs boson decaying into $b\bar{b}$ with branching ratio $\beta$, and $V$ is a
$Z^{0}$ boson decaying into $e^{+}e^{-}$, $\mu^{+}\mu^{-}$, or $\nu\bar{\nu}$.
This search is then combined with previous searches for $H^{0}V$ where $V$ is a
$W^{\pm}$ boson or a hadronically decaying $Z^{0}$. The data sample consists of
$106 \pm 4$ pb$^{-1}$ of $p\bar{p}$ collisions at $\sqrt{s}=1.8$ TeV
accumulated by the Collider Detector at Fermilab. Observing no evidence of a
signal, we set 95% Bayesian credibility level upper limits on
$\sigma(p\bar{p}\to H^{0}V)\times\beta$. For $H^0$ masses of 90, 110 and 130
GeV/$c^{2}$, the limits are 7.8, 7.2, and 6.6 pb respectively.


title:
Measurement of the branching fractions of psi(2S) -> 3(pi+pi-) and J/psi
  -> 2(pi+pi-)

abstract:
  Using data samples collected at sqrt(s) = 3.686GeV and 3.650GeV by the BESII
detector at the BEPC, the branching fraction of psi(2S) -> 3(pi+pi-) is
measured to be [4.83 +- 0.38(stat) +- 0.69(syst)] x 10^-4, and the relative
branching fraction of J/psi -> 2(pi+pi-) to that of J/psi -> mu+mu- is measured
to be [5.86 +- 0.19(stat) +- 0.39(syst)]% via psi(2S) -> (pi+pi-)J/psi, J/psi
-> 2(pi+pi-). The electromagnetic form factor of 3(pi+pi-) is determined to be
0.21 +- 0.02 and 0.20 +- 0.01 at sqrt(s) = 3.686GeV and 3.650GeV, respectively.


title:
Search for lepton flavor violating decays tau- -> l- pi0, l- eta, l-
  eta'

abstract:
  We have searched for lepton flavor violating semileptonic tau decays using a
data sample of 153.8/fb accumulated with the Belle detector at the KEKB e+e-
collider. For the six decay modes studied, the observed yield is compatible
with the estimated background and the following upper limits are set at the 90%
confidence level: B(tau- -> e- eta) < 2.3 x 10^-7, B(tau- -> mu- eta) < 1.5 x
10^-7, B(tau- -> e- pi0) < 1.9 x 10^-7, B(tau- -> mu- pi0) < 4.1 x 10^-7,
B(tau- -> e- eta') < 10 x 10^-7, and B(tau- -> mu- eta') < 4.7 x 10^-7. These
results are 10 to 64 times more restrictive than previous limits.


title: The First Year at LHC: Diffractive Physics

abstract:
  At the LHC, diffractive physics will be explored by the dedicated experiment
TOTEM whose Technical Design Report has been approved in Summer 2004. The
experimental programme will be carried out partly in TOTEM standalone mode for
purely forward phenomena like elastic scattering, and partly in collaboration
with CMS for processes requiring a full rapidity coverage. ATLAS and ALICE are
interested in diffraction for a later stage.
  This article presents the TOTEM/CMS running scenario for diffractive physics
in the first year of LHC. We discuss which processes are within reach and with
which statistics they can be measured.


title:
Hadronic Mass Spectrum Analysis of D+ into K- pi+ mu+ nu Decay and
  Measurement of the K*(892)^0 Mass and Width

abstract:
  We present a Kpi mass spectrum analysis of the four-body semileptonic charm
decay D+ into K- pi+ mu+ nu in the range of 0.65 GeV < mKpi < 1.5 GeV. We
observe a non-resonant contribution of 5.30 +- 0.74 +0.99 -0.51 % with respect
to the total D+ into K- pi+ mu+ nu decay. For the K*(892)^0 resonance, we
obtain a mass of 895.41 +- 0.32 +0.35 -0.36 MeV, a width of 47.79 +- 0.86 +1.3
-1.1 MeV, and a Blatt-Weisskopf damping factor parameter of 3.96 +- 0.54 +0.72
-0.90 GeV^(-1). We also report 90 % CL upper limits of 4 % and 0.64 % for the
branching ratios of D+ into K*(1680)^0 mu+ nu with respect to D+ into K- pi+
mu+ nu and D+ into K*(1430)^0 mu+ nu with respect to D+ into K- pi+ mu+ nu,
respectively.


title: Improved Measurement of the Electroweak Penguin Process B->Xsll

abstract:
  We present an improved measurement of the branching fraction for the
electroweak penguin process B->Xsll, where l is an electron or a muon and Xs is
a hadronic system containing an s-quark. The measurement is based on a sample
of 152*10^6 Upsilon(4S) -> BB events collected with the Belle detector at the
KEKB energy asymmetric e+e- collider. The Xs hadronic system is reconstructed
from one K^{+-} or K^{0}_{S} and up to four pions, where at most one pion can
be neutral. Averaging over both lepton flavors, the inclusive branching
fraction is measured to be
Br(B->Xsll)=(4.11+-0.83(stat)+0.85-0.81(syst))*10^{-6} for M_ll > 0.2GeV/c2.


title:
Search for D^0 - barD^0 Mixing in the Dalitz Plot Analysis of D^0 -->
  K_S^0 pi^+ pi^-

abstract:
  The resonant substructure in D0 --> K0S pi+ pi- decays is described by a
combination of ten quasi two-body intermediate states which include both
CP-even and CP-odd eigenstates and one doubly-Cabibbo suppressed channel. We
present a formalism that connects the variation in D0 decay time over the
Dalitz plot with the mixing parameters, x and y, that describe off-shell and
on-shell D0-D0B mixing. We analyze the CLEO II.V data sample and find the
parameters x and y are consistent with zero. We limit (-4.7 < x < 8.6)% and
(-6.1 < y < 3.5)% at the 95\% confidence level


title: Observation of B+ -> p Lambdabar gamma

abstract:
  We report the first observation of the radiative hyperonic B decay B+ -> p
Lambdabar gamma, using a 140 fb^{-1} data sample recorded on the Upsilon(4S)
resonance with the Belle detector at the KEKB asymmetric energy e+e- collider.
The measured branching fraction is B(B+ -> p Lambdabar gamma) = (2.16
^{+0.58}_{-0.53} \pm 0.20) \times 10^{-6}. We examine its M_pLambdabar
distribution and observe a peak near threshold. This feature is expected by the
short-distance b -> s gamma transition. A search for B+ -> p Sigmabar gamma
yields no significant signal and we set a 90% confidence-level upper limit on
the branching fraction of B(B+ -> p Sigmabar gamma) < 4.6 \times 10^{-6}.


title:
Study of the Baryon-Antibaryon Low-Mass Enhancements in Charmless
  Three-body Baryonic B Decays

abstract:
  The angular distributions of the baryon-antibaryon low-mass enhancements seen
in the charmless three-body baryonic B decays B+ -> p pbar K+, B0 -> p pbar Ks,
and B0 -> p Lambdabar pi- are reported. A quark fragmentation interpretation is
supported, while the gluonic resonance picture is disfavored. Searches for the
Theta+ and Theta++ pentaquarks in the relevant decay modes and possible
glueball states G with 2.2 GeV/c2 < M-ppbar < 2.4 GeV/c2 in the ppbar systems
give null results. We set upper limits on the products of branching fractions,
B(B0 -> Theta+ p)\times B(Theta+ -> p Ks) < 2.3 \times 10^{-7}, B(B+ -> Theta++
pbar) \times B(Theta++ -> p K+) < 9.1 \times 10^{-8}, and B(B+ -> G K+) \times
B(G -> p pbar) < 4.1 \times 10^{-7} at the 90% confidence level. The analysis
is based on a 140 fb^{-1} data sample recorded on the Upsilon(4S) resonance
with the Belle detector at the KEKB asymmetric-energy e+e- collider.


title:
Measurement of the p-pbar -> Wgamma + X cross section at sqrt(s) = 1.96
  TeV and WWgamma anomalous coupling limits

abstract:
  The WWgamma triple gauge boson coupling parameters are studied using p-pbar
-> l nu gamma + X (l = e,mu) events at sqrt(s) = 1.96 TeV. The data were
collected with the DO detector from an integrated luminosity of 162 pb^{-1}
delivered by the Fermilab Tevatron Collider. The cross section times branching
fraction for p-pbar -> W(gamma) + X -> l nu gamma + X with E_T^{gamma} > 8 GeV
and Delta R_{l gamma} > 0.7 is 14.8 +/- 1.6 (stat) +/- 1.0 (syst) +/- 1.0 (lum)
pb. The one-dimensional 95% confidence level limits on anomalous couplings are
-0.88 < Delta kappa_{gamma} < 0.96 and -0.20 < lambda_{gamma} < 0.20.


title: Improved Measurement of the CKM Angle alpha Using B0->rho+rho- Decays

abstract:
  We present results from an analysis of B0 -> rho+rho- using 232 million
Upsilon(4S) decays collected with the BABAR detector at the PEP-II
asymmetric-energy $B$ Factory at SLAC. We measure the longitudinal polarization
fraction f_L = 0.978 +- 0.014 (stat) +0.021 -0.029 (syst) and the CP-violating
parameters SLong = -0.33 +- 0.24 (stat) +0.08 -0.14 (syst) and CLong = -0.03 +-
0.18 (stat) +- 0.09 (syst). Using an isospin analysis of B -> rho rho decays we
determine the unitarity triangle alpha. The solution compatible with the
Standard Model is alpha = (100 +- 13) degrees.


title: The LEP Legacy

abstract:
  In this lecture we shall summarize the scientific legacy of LEP, in
particular in connection with the Standard Model of Particle Physics; we shall
also discuss some historical and sociological aspects of the experimentation at
LEP.


title:
Measurement of event shape distributions and moments in e+e- -> hadrons
  at 91-209 GeV and a determination of alpha_s

abstract:
  We have studied hadronic events from e+e- annihilation data at centre-of-mass
energies from 91 to 209 GeV. We present distributions of event shape
observables and their moments at each energy and compare with QCD Monte Carlo
models. From the event shape distributions we extract the strong coupling
alpha_s and test its evolution with energy scale. The results are consistent
with the running of alpha_s expected from QCD. Combining all data, the value of
alpha_s(M_Z) is determined to be alpha_s(M_Z) = 0.1191 +- 0.0005 (stat.) +-
0.0010 (expt.) +- 0.0011 (hadr.) +- 0.0044 (theo.). The energy evolution of the
moments is also used to determine a value of alpha_s with slightly larger
errors: alpha_s(M_Z) = 0.1223 +- 0.0005 (stat.) +- 0.0014 (expt.) +- 0.0016
(hadr.) +0.0054 -0.0036 (theo.).


title:
Searches for CP Violation and \pi\pi S-Wave in the Dalitz-Plot Analysis
  of D0 --> \pi+\pi-\pi0

abstract:
  In e+e- collisions recorded using the CLEO II.V detector we have studied the
Cabibbo suppressed decay of D0 -> pi+pi-pi0 with the initial flavor of the D0
tagged by the decay D*+ -> D0pi+. We use the Dalitz-plot analysis technique to
measure the resonant substructure in this final state and observe \rho\pi and
non-resonant contributions by fitting for their amplitudes and relative phases.
We describe the pipi S-wave with a K-matrix formalism and limit this
contribution to the rate to be < 2.5% @95% confidence level, in contrast to the
large rate observed in D+ -> pi+pi-pi+ decay. Using the amplitudes and phases
from this analysis, we calculate an integrated CP asymmetry of
0.01^{+0.09}_{-0.07} +/- 0.05.


title:
NOvA Proposal to Build a 30 Kiloton Off-Axis Detector to Study Neutrino
  Oscillations in the Fermilab NuMI Beamline

abstract:
  This is an updated version of the NOvA proposal. The detector is a 30 kiloton
tracking calorimeter, 15.7 m by 15.7 m by 132 m long, with alternating
horizontal and vertical rectangular cells of liquid scintillator contained in
PVC extrusion modules. Light from each 15.7 m long cell of liquid scintillator
filled PVC is collected by a wavelength shifting fiber and routed to an
avalanche photodiode pixel. The reach of NOvA for sin^2(2_theta_13) and related
topics is increased relative to earlier versions of the proposal with the
assumption of increased protons available from the Fermilab Main Injector
following the end of Tevatron Collider operations in 2009.


title: European underground laboratories: An overview

abstract:
  Underground laboratories are complementary to those where the research in
fundamental physics is made using accelerators. This report focus on the
logistic and on the background features of the most relevant laboratories in
Europe, stressing also on the low background facilities available. In
particular the report is focus on the laboratories involved in the new
Europeean project ILIAS with the aim to support the European large
infrastructures operating in the astroparticle physics area.


title: Measurement of the Branching Fraction of Upsilon(4S) --> B0B0bar

abstract:
  We report the first measurement of the branching fraction f00 for Upsilon(4S)
--> B0B0bar. The data sample consists of 81.7 fb^-1 collected at the
Upsilon(4S) resonance with the BABAR detector at the PEP-II asymmetric-energy
e^+e^- storage ring. Using partial reconstruction of the decay B0bar --> D^{*+}
\ell^{-} \bar{\nu}_{\ell} in which only the charged lepton and the soft pion
from the decay D^{*+} --> D0 pi^+ are reconstructed, we obtain f00 = 0.487 \pm
0.010(stat) \pm 0.008(sys). Our result does not depend on the branching
fractions of B0bar --> D^{*+} \ell^{-} \bar{\nu}_{\ell} and D^{*+} --> D0 pi^+
decays, on the ratio of the charged and neutral B meson lifetimes, nor on the
assumption of isospin symmetry.


title: Atmospheric neutrino oscillations

abstract:
  The latest results from the Soudan 2, MACRO and SuperKamiokande experiments
on atmospheric neutrino oscillations are summarised and discussed. In
particular a discussion is made on the Monte Carlo simulations used for the
atmospheric neutrino flux.


title:
Measurement of Absolute Hadronic Branching Fractions of D Mesons and
  e^+e^- --> D barD Cross Sections at E_cm = 3773 MeV

abstract:
  Using 55.8 pb^-1 of e^+e^- collisions recorded at the psi(3770) resonance
with the CLEO-c detector at CESR, we determine absolute hadronic branching
fractions of charged and neutral D mesons using a double tag technique. Among
measurements for three D^0 and six D^+ modes, we obtain reference branching
fractions B(D^0 -> 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. Final state radiation is included in these branching
fractions by allowing for additional, unobserved, photons in the final state.
Using a determination of the integrated luminosity, we also extract the cross
sections sigma(e^+e^- -> D^0 \bar D^0)=(3.60 +- 0.07 +0.07-0.05) nb and
sigma(e^+e^- -> D^+D^-)=(2.79 +- 0.07 +0.10-0.04) nb.


title:
Combination of CDF and D0 Limits on a Gauge Mediated SUSY Model Using
  Diphoton and Missing Transverse Energy Channel

abstract:
  We combine the results of the CDF and D0 searches for chargino and neutralino
production in Gauge-Mediated SUSY using the two-photon and missing Et channel.
The data are p-pbar collisions produced at the Tevatron with sqrt(s)=1.96 TeV,
with 202 pb^-1 collected at CDF and 263 pb^-1 collected at D0. The combined
limit excludes a chargino mass less than 209 GeV/c^2. This result significantly
extends the individual experimental limits.


title:
Correlating Neutrino Flux and Mental Activity in the Super-Kamiokande-I
  Experiment

abstract:
  A search for a non-random co-variation between the Neutrino Flux and Mental
Activity was undertaken, using the 5-day period version of the SK-I data taken
from May 31st, 1996 to July 15th, 2001. For the whole 1996-2001 period, a
significant correlation between the Neutrino Flux and Mental Activity was found
for each of the two midnight hours, i.e. for each of the two hours between
23:00-1:00. A significant correlation was also found across all hours for the
whole year of 1998. It is not clear why this particular year should have been
different from the other calendar years of 1996-2001. More specifically,
significant correlations were also found for each of its hours around noon,
i.e. for each of the hours between 10:00-16:00, for the year of 1998. An
attempt was made to interpret why significant correlations were found only for
midnight hours and hours around noon, but not for any other hours: when the
sun-earth axis and the staff-detector axis coincided, the likelihood increased
that staff neutrinos (if any) were counted - as solar neutrinos. Unruh's second
quantization in the Kerr metric was suggested as an example of theoretical
support for this conjecture that Mental Activity is a quantum-gravitational
process which influences the Neutrino Flux.


title:
Measurement of Partial Widths and Search for Direct CP Violation in
  $D^0$ Meson Decays to $K^-K^+$ and $\pi^-\pi^+$

abstract:
  We present a measurement of relative partial widths and decay rate CP
asymmetries in $K^-K^+$ and $\pi^-\pi^+$ decays of $\Do$ mesons produced in
$p\bar{p}$ collisions at $\sqrt{s} = 1.96 \TeV$. We use a sample of
$2\times10^5$ $D^{\ast+}\myto D^0\pi^+$ (and charge conjugate) decays with the
$D^0$ decaying to $K^-\pi^+$, $K^-K^+$, and $\pi^-\pi^+$, corresponding to $123
{\rm pb}^{-1}$ of data collected by the Collider Detector at Fermilab II
experiment at the Fermilab Tevatron collider. No significant direct CP
violation is observed. We measure $\KKtokpi = 0.0992 \pm 0.0011 \pm 0.0012$,
$\PIpitokpi = 0.03594 \pm 0.00054 \pm 0.00040$, $A_{CP}(K^-K^+) = (2.0 \pm 1.2
\pm 0.6) %$, and $A_{CP}(\pi^-\pi^+) = (1.0 \pm 1.3 \pm 0.6) %$, where, in all
cases, the first uncertainty is statistical and the second is systematic.


title: Prompt Photon Production at HERA and LEP

abstract:
  Results on isolated prompt photon production are presented. The measurements
were performed at HERA in deep inelastic ep scattering and photoproduction, as
well as at LEP in photon photon collisions. Differential cross sections are
shown for inclusive prompt photons and those accompanied by a jet. The results
are compared to predictions of perturbative QCD calculations in next to leading
order and to predictions of the event generators PYTHIA and HERWIG.


title: LHC and VLHC Based ep Colliders: E-Linac vs e-Ring

abstract:
  Linac-ring analogues of the LHC and VLHC based standard type ep collider
proposals are discussed. It is shown that sufficiently high luminosities can be
obtained with TESLA-like linacs, whereas essential modifications are required
for CLIC technology. The physics search potential of proposed ep colliders is
demonstrated using pair production of heavy quarks as an example.


title: Evidence for the Decay B+- --> K*+- pi0

abstract:
  We have measured the process B+- --> (K*+- --> K+- pi0) pi0 based on 232
million Y(4S) --> BBbar decays collected with the BaBar detector at the PEP-II
asymmetric-energy B Factory at SLAC. From a signal yield of 89 +- 26 events we
obtain the branching fraction BR(B+- --> K*+- pi0)=[6.9 +- 2.0 (stat) +- 1.3
(syst)] x10^-6 with a statistical significance of 3.6 standard deviations
including systematic uncertainties, and a charge asymmetry of 0.04 +- 0.29
(stat) +- 0.05 (syst).


title: Exclusive electroproduction of $\phi$ mesons at HERA

abstract:
  Exclusive electroproduction of $\phi$ mesons has been studied in $e^\pm p$
collisions at $\sqrt{s}=318 \gev$ with the ZEUS detector at HERA using an
integrated luminosity of 65.1 pb$^{-1}$. The $\gamma^*p$ cross section is
presented in the kinematic range $2<Q^2<70 \gev^2$, $35<W<145 \gev$ and
${|t|}<0.6 \gev^2$. The cross sections as functions of $Q^2$, $W$, $t$ and
helicity angle $\theta_h$ are compared to cross sections for other vector
mesons. The ratios $R$ of the cross sections for longitudinally and
transversely polarized virtual photons are presented as functions of $Q^2$ and
$W$. The data are also compared to predictions from theoretical models.


title: Spin physics with antiprotons

abstract:
  New possibilities arising from the availability at GSI of antiproton beams,
possibly polarised, are discussed. The investigation of the nucleon structure
can be boosted by accessing in Drell-Yan processes experimental asymmetries
related to cross-sections in which the parton distribution functions (PDF) only
appear, without any contribution from fragmentation functions; such processes
are not affected by the chiral suppression of the transversity function
$h_1(x)$. Spin asymmetries in hyperon production and Single Spin Asymmetries
are discussed as well, together with further items like electric and magnetic
nucleonic form factors and open charm production. Counting rates estimations
are provided for each physical case. The sketch of a possible experimental
apparatus is proposed.


title: Compton Scattering of Quasi-Real Virtual Photons at LEP

abstract:
  Compton scattering of quasi-real virtual photons, gamma e+- -> gamma e+-, is
studied with 0.6fb-1 of data collected by the L3 detector at the LEP e+e-
collider at centre-of-mass energies root(s')=189-209GeV. About 4500 events
produced by the interaction of virtual photons emitted by e+- of one beam with
e-+ of the opposite beam are collected for effective centre-of-mass energies of
the photon-electron and photon-positron systems in the range from root(s')=
35GeV up to root(s')=175GeV, the highest energy at which Compton scattering was
ever probed. The cross sections of the gamma e+- -> gamma e+- process as a
function of root(s') and of the rest-frame scattering angle are measured,
combined with previous L3 measurements down to root(s')~20GeV, and found to
agree with the QED expectations.


title: Measurement of phi_3 with Dalitz Plot Analysis of B+- -> D K*+- Decay

abstract:
  We present a measurement of the unitarity triangle angle phi_3 using a Dalitz
plot analysis of the three-body decay of the neutral D meson from the B+- -> D
K*+- process. Using a 253 fb-1 data sample collected by the Belle experiment,
we obtain 56 signal candidates for B+- -> D K*+-, where the neutral D meson
decays into K_S pi+ pi-. From a maximum likelihood fit we obtain
phi_3=112+-35(stat)+-9(syst)+-11(model)+-8(nonresonant B -> D K_S pi).


title: Production and decay of Xic0 at BABAR

abstract:
  Using 116.1 fb^-1 of data collected by the BABAR detector, we present an
analysis of Xic0 production in B decays and from the ccbar continuum, with the
Xic0 decaying into Omega- K+ and Xi- pi+ final states. We measure the ratio of
branching fractions B(Xic0 -> Omega- K+)/B(Xic0 -> Xi- pi+) to be 0.294 +-
0.018 +- 0.016, where the first uncertainty is statistical and the second is
systematic. The Xic0 momentum spectrum is measured on and 40 MeV below the
Upsilon(4S) resonance. From these spectra the branching fraction product B(B ->
Xic0 X) x B(Xic0 -> Xi- pi+) is measured to be (2.11 +- 0.19 +- 0.25) x 10^-4
and the cross-section product sigma(e+ e- -> Xic0 X) x B(Xic0 -> Xi- pi+) from
the continuum is measured to be (388 +- 39 +- 41) fb at a center-of-mass energy
of 10.58 GeV.

Z-boson production with two unobserved, back-to-back, hard photons at
  LEP

abstract:
  The double-radiative process e+e- -> Z gamma gamma -> q q~ gamma gamma, where
the two hard photons escape detection at low polar angles into opposite
directions, is studied in 0.62/fb of data collected with the L3 detector at LEP
at centre-of-mass energies between 188.6GeV and 209.2GeV. The cross sections
are measured and found to be consistent with the Standard Model expectations.


title:
Measurement of Exclusive rho+rho- Production in Mid-Virtuality
  Two-Photon Interactions and Study of the gamma gamma* -> rho rho Process at
  LEP

abstract:
  Exclusive rho+rho- production in two-photon collisions between a quasi-real
photon, gamma, and a mid-virtuality photon, gamma*, is studied with data
collected at LEP at centre-of-mass energies root(s)=183-209GeV with a total
integrated luminosity of 684.8pb^-1. The cross section of the gamma gamma* ->
rho+ rho- process is determined as a function of the photon virtuality, Q^2,
and the two-photon centre-of-mass energy, W_gg, in the kinematic region:
0.2GeV^2 < Q^2 <0.85GeV^2 and 1.1GeV < W_gg < 3GeV. These results, together
with previous L3 measurements of rho0 rho0 and rho+ rho- production, allow a
study of the gamma gamma* -> rho rho process over the Q^2-region 0.2GeV^2 < Q^2
< 30 GeV^2.


title: Atomic CP-violating polarizability

abstract:
  Searches for CP violating effects in atoms and molecules provide important
constrains on competing extensions to the standard model of elementary
particles. In particular, CP violation in an atom leads to the CP-odd (T,P-odd)
polarizability $\beta^\mathrm{CP}$: a magnetic moment $\mu^\mathrm{CP}$ is
induced by an electric field $\mathcal{E}_0$ applied to an atom,
$\mu^\mathrm{CP} = \beta^\mathrm{CP} \mathcal{E}_0 $. We estimate the
CP-violating polarizability for rare-gas (diamagnetic) atoms He through Rn. We
relate betaCP to the permanent electric dipole moment (EDM) of the electron and
to the scalar constant of the CP-odd electron-nucleus interaction. The analysis
is carried out using the third-order perturbation theory and the
Dirac-Hartree-Fock formalism. We find that, as a function of nuclear charge Z,
betaCP scales steeply as Z^5 R(Z), where slowly-varying R(Z) is a relativistic
enhancement factor. Finally, we evaluate a feasibility of setting a limit on
electron EDM by measuring CP-violating magnetization of liquid Xe. We find that
such an experiment could provide competitive bounds on electron EDM only if the
present level of experimental sensitivity to ultra-weak magnetic fields
[Kominis et al., Nature 422, 596 (2003)] is improved by several orders of
magnitude.


title:
Search for neutral supersymmetric Higgs bosons in multijet events at
  sqrt(s)=1.96 TeV

abstract:
  We have performed a search for neutral Higgs bosons produced in association
with bottom quarks in $p\bar{p}$ collisions, using 260 $pb^{-1}$ of data
collected with the D0 detector in Run II of the Fermilab Tevatron Collider. The
cross sections for these processes are enhanced in many extensions of the
standard model (SM), such as in its minimal supersymmetric extension at large
tan$\beta$. The results of our analysis agree with expectations from the SM,
and we use our measurements to set upper limits on the production of neutral
Higgs bosons in the mass range of 90 to 150 GeV.


title:
Production of WZ Events in p-barp Collisions at sqrt(s)=1.96 TeV and
  Limits on Anomalous WWZ Couplings

abstract:
  We present results from a search for WZ production with subsequent decay to l
nu l'-bar l' (l and l'=electron or muon) using 0.30 fb^(-1) of data collected
by the DO experiment between 2002 and 2004 at the Tevatron. Three events with
WZ decay characteristics are observed. With an estimated background of
0.71+-0.08 events, we measure the WZ production cross section to be 4.5 (+3.8
-2.6) pb, with a 95% C.L. upper limit of 13.3 pb. The 95% C.L. limits for
anomalous WWZ couplings are found to be -2.0 < Delta kappa_Z < 2.4 for form
factor scale Lambda = 1 TeV, and -0.48 < lambda_Z < 0.48 and -0.49 < Delta
g_1^Z < 0.66 for Lambda = 1.5 TeV.


title:
Measurement of the azimuthal angle distribution of leptons from W boson
  decays as a function of the W transverse momentum in proton-antiproton
  collisions at sqrt(s)=1.8 TeV

abstract:
  We present the first measurement of the A_2 and A_3 angular coefficients of
the W boson produced in proton-antiproton collisions. We study W-> e+nu and W->
mu+nu candidate events produced in association with at least one jet at CDF,
during Run Ia and Run Ib of the Tevatron at sqrt(s)=1.8 TeV. The corresponding
integrated luminosity was 110 pb^-1. The jet balances the transverse momentum
of the W and introduces QCD effects in W boson production. The extraction of
the angular coefficients is achieved through the direct measurement of the
azimuthal angle of the charged lepton in the Collins-Soper rest-frame of the W
boson. The angular coefficients are measured as a function of the transverse
momentum of the W boson. The electron, muon, and combined results are in good
agreement with the Standard Model prediction, up to order alpha_s^2 in QCD.


title: In-situ calibration of forward hadron calorimeters of CMS at LHC

abstract:
  Physical possibility for bending the LHC protons (or ions) a huge angle of
1-20 degrees in the energy range of 0.45 to 7 TeV by means of a bent channeling
crystal of Silicon or Germanium is demonstrated. Such an application can be
useful for calibration of CMS (or ATLAS) calorimeters in situ by the LHC beam
of precisely known energy. We show by simulations that such an application
would be feasible at the LHC, and report the experience of IHEP Protvino in
bending 70 GeV protons by 9 degrees (150 mrad) during 10 years in 1994-2004
experiments.


title: Recent Results from the SIMPLE Dark Matter Search

abstract:
  SIMPLE is an experimental search for evidence of spin-dependent dark matter,
based on superheated droplet detectors using C$_{2}$ClF$_{5}$. We report
preliminary results of a 0.6 kgdy exposure of five one liter devices, each
containing $\sim$10 g active mass, in the 1500 mwe LSBB (Rustrel, France). In
combination with improvements in detector sensitivity, the results exclude a
WIMP--proton interaction above 5 pb at M$_{\chi}$ = 50 GeV/c$^{2}$.


title: Time-Dependent CP-Violating Asymmetries in b -> s qbar q Transitions

abstract:
  We present new measurements of CP-violation parameters in B0 -> phiK0,
K+K-Ks, f0(980)Ks, eta'Ks, omegaKs and Kspi0 decays based on a sample of 275 x
10^6 BBbar pairs collected at the Upsilon(4S) resonance with the Belle detector
at the KEKB energy-asymmetric e+e- collider. One neutral B meson is fully
reconstructed in one of the specified decay channels, and the flavor of the
accompanying B meson is identified from its decay products. CP-violation
parameters for each of the decay modes are obtained from the asymmetries in the
distributions of the proper-time intervals between the two B decays. The
combined result for the B0->phiK0, K+K-Ks, f0(980)Ks, eta'Ks, omegaKs, Kspi0,
and previously reported KsKsKs decays differs from the SM expectation by 2.4
standard deviations.


title: The A - dependence of $K^{0}$ and $\Lambda$ neutrinoproduction on nuclei

abstract:
  For the first time, the A- dependence of the production of $K^0$, $\Lambda$
and, for comparison, $\pi^-$ mesons is investigated in neutrinonuclear
reactions, using the data obtained with SKAT bubble chamber. An exponential
parametrization ($\sim A^{\beta}$) of the particle yields results in
${\beta}_{V^0} = 0.20 \pm 0.05$ for $V^0$ particles (combined $K^0$ and
$\Lambda$), while for $\pi^-$ mesons the A- dependence is much weaker,
${\beta}_{\pi^-} = 0.068 \pm 0.007$. A nuclear enhancement of the ratio
$K^0/\pi^-$ is found; this ratio increases from $0.055 \pm 0.013$ for $\nu N$-
interactions up to $0.070 \pm 0.011$ at $A \approx 21$ and $0.099 \pm 0.011$ at
$A \approx 45$. It is observed, that the multiplicity rise of $V^0$'s occures
predominantely in the backward hemisphere of the hadronic c.m.s. It is shown,
that the A- dependence of the nuclear enhancement of the ${\Lambda}^0$ and
$\pi^-$ yields can be reproduced in the framework of a model, incorporating the
secondary intranuclear interactions of pions originating from the primary $\nu
N$- interactions, while only (29$\pm$9)% of that for $K^0$ at $A \approx 45$
can be attributed to intranuclear interactions.


title: Single-spin asymmetries in semi-inclusive pion production

abstract:
  For the first time single-spin asymmetries in semi-inclusive pion production
are measured by the HERMES experiment with a transversely polarised hydrogen
target. Two different sine-modulations are extracted which can be related to
the transversity \delta q(x) and Sivers f_{1T}^{\perp q}(x) quark distribution
functions. The extracted sine-moments still contain small sub-leading twist
contributions which can be extracted from HERMES data combining the results
from the transversely polarised hydrogen target with previously measured
results from a longitudinally polarised hydrogen target.


title:
Exotic narrow resonance searches in the system Lambda K0s in p+propane
  collisions at 10 GeV/c

abstract:
  Experimental data from the 2m propane bubble chamber have been analyzed to
search for an exotic baryon states, in the $\Lambda K^0_s$ decay mode for the
reaction p+$C_3H_8$ at 10 GeV/c. The invariant mass spectrum $\Lambda K^0_s$
observe a narrow peaks at 1750$\pm$18, 1795$\pm$18,1850$\pm19$ MeV/$c^2$ and
full widths of $\Gamma_{exp.}$= 32$\pm$6, 44$\pm$15, 29.0$\pm$8 MeV/$c^2$. The
statistical significance of these peaks has been estimated as 5.6, 3.3 and 3.0
S.D., respectively. There are the small enhancements in mass regions of
(1650-1675) and (1925-1950) МэВ/с$^2$. These would be
candidates for the $N^0$ or the $\Xi^0$ pentaquark states.
  The investigation has been performed at the Veksler and Baldin Laboratory of
High Energies, JINR.


title: Experimental Search for Pentaquarks

abstract:
  The experimental evidence for pentaquarks, both old an new, is discussed.
Constraints due to $K^+N$ scattering data from previous decades is first
reviewed, followed by experiments with positive evidence and those with null
results. Finally, the problem of the narrow width of the Theta+ pentaquark is
discussed, along with theoretical implications.


title:
Evidence for the Strangeness S=+1 Pentaquark from LEPS and CLAS
  Experiments

abstract:
  There are now several experimental collaborations that have seen evidence for
a narrow state in the mass spectrum of the ($nK^+$) system. Two of these
experiments, from the LEPS collaboration in Japan and the CLAS collaboration in
the USA, are described briefly. Both use similar photoproduction reactions with
a $K^+K^-$ pair in the final state. In addition, data from the CLAS
collaboration for the $\gamma p \to K_s K^+ n$ reaction are presented for the
first time, which has no prominant peak in the ($nK^+$) mass spectrum when the
$K_s$ angle is limited to forward angles.


title: MACRO results on atmospheric neutrinos

abstract:
  We discuss the final results of the MACRO experiment on atmospheric neutrino
oscillations. The data concern event topologies with average neutrino energies
of ~3 and ~50 GeV. Multiple Coulomb Scattering of the high energy muons was
used to estimate the neutrino energy event by event. The angular distributions,
the L/E_nu distribution, the particle ratios and the absolute fluxes all favor
nu_mu --> nu_tau oscillations with maximal mixing and Delta m^2 ~0.0023 eV^2.
Emphasis is given to measured ratios which are not affected by Monte Carlo (MC)
absolute normalization; a discussion is made on MC uncertainties. A preliminary
search for possible Lorentz invariance violation contributions to atmospheric
neutrino oscillations is presented and discussed.


title: Studies of CP violation in B->J/psi K* decays

abstract:
  CP violation in $B\to J/\psi K^*$ decays is studied using an angular analysis
in a data sample of 253 fb$^{-1}$ recorded with the Belle detector at the KEKB
$e^+e^-$ collider. The flavor separated measurements of the decay amplitudes
indicate no evidence for direct CP violation. T-odd CP violation is studied
using the asymmetries in triple product correlations, and the results are
consistent with the Standard Model null predictions. The time-dependent angular
analysis gives the following values of CP violating parameters: $\sin 2\phi_1 =
0.24 \pm 0.31 \pm 0.05$ and $\cos 2\phi_1 = 0.56 \pm 0.79 \pm 0.11$.


title:
Limits on WIMP cross-sections from the NAIAD experiment at the Boulby
  Underground Laboratory

abstract:
  The NAIAD experiment (NaI Advanced Detector) for WIMP dark matter searches at
the Boulby Underground Laboratory (North Yorkshire, UK) ran from 2000 until
2003. A total of 44.9 kg x years of data collected with 2 encapsulated and 4
unencapsulated NaI(Tl) crystals with high light yield were included in the
analysis. We present final results of this analysis carried out using pulse
shape discrimination. No signal associated with nuclear recoils from WIMP
interactions was observed in any run with any crystal. This allowed us to set
upper limits on the WIMP-nucleon spin-independent and WIMP-proton
spin-dependent cross-sections. The NAIAD experiment has so far imposed the most
stringent constraints on the spin-dependent WIMP-proton cross-section.


title:
Search for Supersymmetry via Associated Production of Charginos and
  Neutralinos in Final States with Three Leptons

abstract:
  A search for associated production of charginos and neutralinos is performed
using data recorded with the D0 detector at a ppbar center-of-mass energy of
1.96 TeV at the Fermilab Tevatron Collider. This analysis considers final
states with missing transverse energy and three leptons, of which at least two
are electrons or muons. No evidence for supersymmetry is found in a dataset
corresponding to an integrated luminosity of 320 pb-1. Limits on the product of
the production cross section and leptonic branching fraction are set. For the
minimal supergravity model, a chargino lower mass limit of 117 GeV at the 95%
C.L. is derived in regions of parameter space with enhanced leptonic branching
fractions.


title: The OPERA experiment

abstract:
  OPERA is a neutrino oscillation experiment designed to perform a nu\_tau
appearance search at long distance in the future CNGS beam from CERN to Gran
Sasso. It is based on the nuclear emulsion technique to distinguish among the
neutrino interaction products the track of a tau produced by a nu\_tau and its
decay tracks. The OPERA detector is presently under construction in the Gran
Sasso underground laboratory, 730 km from CERN, and will receive its first
neutrinos in 2006. The experimental technique is reviewed and the development
of the project described. Foreseen performances in measuring nu\_tau appearance
and also in searching for nu\_e appearance are discussed.


title: Selected Aspects of Neutron Decay

abstract:
  Precision measurements of neutron decay offer complementary access to
particle physics at small distance scales or high energies. In particular they
allow tests of the V-A structure of the weak interaction. Among many
experimental activities which are ongoing around the world we present two new
experiments which are planned or studied for the near future. While the neutron
lifetime still bears significant experimental uncertainties and thus has to be
studied with greatest precision the two-body decay ($n\to H\bar\nu$) of the
neutron has not yet been observed. Despite its small branching fraction it
offers many possibilities in the framework of particle physics. Both cases are
addressed in this contribution.


title:
Measurement of Time-Dependent CP-Violating Asymmetries and Constraints
  on sin(2 beta+gamma) with Partial Reconstruction of B->D*-+pi+- Decays

abstract:
  We present a measurement of the time-dependent CP-violating asymmetries in
decays of neutral B mesons to the final states D*-+ pi+-, using approximately
232 million BBbar events recorded by the BABAR experiment at the PEP2 e+e-
storage ring. Events containing these decays are selected with a partial
reconstruction technique, in which only the high-momentum pi+- from the B decay
and the low-momentum pi-+ from the D*-+ decay are used. % We measure the
parameters related to 2beta+gamma to be a_D*pi=-0.034 +- 0.014 +- 0.009 and
c_l_D*pi = -0.019 +- 0.022 +- 0.013. With some theoretical assumptions, we
interpret our results in term of the lower limits |\sin(2beta+gamma)|> 0.62
(0.35) at 68% (90%) confidence level.


title: Electrical Properties of Carbon Fiber Support Systems

abstract:
  Carbon fiber support structures have become common elements of detector
designs for high energy physics experiments. Carbon fiber has many mechanical
advantages but it is also characterized by high conductivity, particularly at
high frequency, with associated design issues. This paper discusses the
elements required for sound electrical performance of silicon detectors
employing carbon fiber support elements. Tests on carbon fiber structures are
presented indicating that carbon fiber must be regarded as a conductor for the
frequency region of 10 to 100 MHz. The general principles of grounding
configurations involving carbon fiber structures will be discussed. To
illustrate the design requirements, measurements performed with a silicon
detector on a carbon fiber support structure at small radius are presented. A
grounding scheme employing copper-kapton mesh circuits is described and shown
to provide adequate and robust detector performance.


title: Complete results for five years of GNO solar neutrino observations

abstract:
  We report the complete GNO solar neutrino results for the measuring periods
GNO III, GNO II, and GNO I. The result for GNO III (last 15 solar runs) is
[54.3 + 9.9 - 9.3 (stat.)+- 2.3 (syst.)] SNU (1 sigma) or [54.3 + 10.2 - 9.6
(incl. syst.)] SNU (1 sigma) with errors combined. The GNO experiment is now
terminated after altogether 58 solar exposure runs that were performed between
May 20, 1998 and April 9, 2003. The combined result for GNO (I+II+III) is [62.9
+ 5.5 - 5.3 (stat.) +- 2.5 (syst.)] SNU (1 sigma) or [62.9 + 6.0 - 5.9] SNU (1
sigma) with errors combined in quadrature. Overall, gallium based solar
observations at LNGS (first in GALLEX, later in GNO) lasted from May 14, 1991
through April 9, 2003. The joint result from 123 runs in GNO and GALLEX is
[69.3 +- 5.5 (incl. syst.)] SNU (1 sigma). The distribution of the individual
run results is consistent with the hypothesis of a neutrino flux that is
constant in time. Implications from the data in particle- and astrophysics are
reiterated.


title: Search for Pentaquarks with HERA-B

abstract:
  A large data set of proton-nucleus collisions at sqrt(s) =41.6 GeV has been
searched for Theta+ and Xi(1862) pentaquark candidates. In 2x10**8 inelastic
events we find no evidence for narrow signals (sigma=5 MeV/c**2) in the Theta+
--> pK0s and Xi--(1862) --> Xi- pi- channels. Upper limits on production cross
sections at mid-rapidity and on ratios of production cross sections to those of
well established resonances are presented.


title:
Measurement of the Cabibbo-Kobayashi-Maskawa angle gamma in B-+ ->
  D(*)K-+ decays with a Dalitz analysis of D -> K0s pi- pi+

abstract:
  We report on a measurement of the Cabibbo-Kobayashi-Maskawa CP-violating
phase gamma through a Dalitz analysis of neutral D decays to K0s pi- pi+ in the
processes B-+ -> D(*)K-+, D* -> D pi0, D gamma. Using a sample of 227 million
BBbar pairs collected by the BaBar detector, we measure the amplitude ratios rB
= 0.12+/-0.08+/-0.03+/-0.04 and rB* = 0.17+/-0.10+/-0.03+/-0.03, the relative
strong phases deltaB = 104+/-45+17-21+16-24, and deltaB*= -64+/-41+14-12+/-15
between the amplitudes A(B- -> Dbar(*)0 K-) and A(B- -> D(*)0 K-), and gamma =
70+/-31+12-10+14-11. The first error is statistical, the second is the
experimental systematic uncertainty and the third reflects the Dalitz model
uncertainty. The results for the strong and weak phases have a two-fold
ambiguity.


title:
The total yields of K^+(892), Sigma^+(1385) and Sigma^0 in
  neutrino-induced reactions at <E_nu> = 10 GeV

abstract:
  Using the data obtained with SKAT bubble chamber, the total yields of
$K^+(892)$, $\Sigma^+(1385)$ and $\Sigma^0$ are estimated for the first time in
neutrino-induced reactions at moderate energies ($<E_{\nu}>$ = 10.4 GeV). It is
shown, that the recently observed \cite{ref1,ref2} enhancement of the $K^0$ and
$\Lambda$ yields in $\nu A$ interactions (as compared to $\nu N$ interactions)
is contributed only slightly by the $K^+(892)$ and $\Sigma^+(1385)$ production,
respectively. The decay contribution to the $K^0$ and $\Lambda$ yields is found
to be in qualitative agreement with higher energy ($<E_\nu> \geq$ 40 GeV) data.
It is shown, that the energy dependence of the $K^+(892)$ mean multiplicity in
$\nu N$ interactions is approximately linear in the range of $<E_{\nu}>
\approx$ 10-60 GeV, while that for $\Sigma^0$ in $\nu A$ interactions (for $A$
= 20-21) is approximately logarithmic in the range of $<E_{\nu}> \approx$
10-150 GeV.


title: Systematic Analysis of Frontier Energy Collider Data

abstract:
  Ignorance of the form new physics will take suggests the importance of
systematically analyzing all data collected at the energy frontier, with the
goal of maximizing the chance for discovery both before and after the turn on
of the LHC.


title:
Neutron Diffraction and Optics of a Noncentrosymmetric Crystal. New
  Feasibility of a Search for Neutron EDM

abstract:
  Recently strong electric fields (up to 10^9 V/cm) have been discovered, which
affect the neutrons moving in noncentrosymmetric crystals. Such fields allow
new polarization phenomena in neutron diffraction and optics and provide, for
instance, a new feasibility of a search for the neutron electric dipole moment
(EDM). A series of experiments was carried out in a few last years on study of
the dynamical diffraction of polarized neutrons in thick (1-10 cm) quartz
crystals, using the forward diffraction beam and Bragg angles close to 90^0. As
well new neutron optics phenomena were investigated. The feasibility of
experiment on a search for neutron EDM using Laue diffraction in crystals
without a center of symmetry was tested at the reactors: WWR-M in Gatchina and
HFR in Grenoble. It was shown that the sensitivity can reach (3 - 6)\cdot
10^{-25}e cm per day for the available quartz crystal and cold neutron beam
flux.


title:
Measurement of the ttbar Production Cross Section in ppbar Collisions at
  sqrt{s} = 1.96 TeV using Kinematic Characteristics of Lepton + Jets Events

abstract:
  We present a measurement of the top quark pair ttbar production cross section
in ppbar collisions at a center-of-mass energy of 1.96 TeV using 230 pb**{-1}
of data collected by the DO detector at the Fermilab Tevatron Collider. We
select events with one charged lepton (electron or muon), large missing
transverse energy, and at least four jets, and extract the ttbar content of the
sample based on the kinematic characteristics of the events. For a top quark
mass of 175 GeV, we measure sigma(ttbar) = 6.7 {+1.4-1.3} (stat) {+1.6- 1.1}
(syst) +/-0.4 (lumi) pb, in good agreement with the standard model prediction.


title: First measurement of the $\pi^+\pi^-$ atom lifetime

abstract:
  The goal of the DIRAC experiment at CERN (PS212) is to measure the
$\pi^+\pi^-$ atom lifetime with 10% precision. Such a measurement would yield a
precision of 5% on the value of the $S$-wave $\pi\pi$ scattering lengths
combination $|a_0-a_2|$. Based on part of the collected data we present a first
result on the lifetime, $\tau=[2.91 ^{+0.49}_{-0.62}]\times 10^{-15}$ s, and
discuss the major systematic errors. This lifetime corresponds to
$|a_0-a_2|=0.264 ^{+0.033}_{-0.020} m_{\pi}^{-1}$.


title: Branching fractions and CP asymmetries in B --> h+ h'-

abstract:
  Relative branching fractions of Bd,Bs --> h+ h'- decays (where h,h'= K or pi)
and direct CP asymmetry in Bd --> K+ pi- have been measured with 180 pb-1 of
data collected by the CDFII detector at the Tevatron collider. This includes
the first BR measurement of a charmless Bs-->PP decay (Bs --> K+K-).


title:
Measurement of |V_ub| near the endpoint of the electron momentum
  spectrum from semileptonic B-meson decays

abstract:
  We report measurements of partial branching fractions of inclusive charmless
semileptonic $B$-meson decays at the endpoint of the electron momentum
spectrum. The measurements are made in six overlapping momentum intervals that
have lower bounds ranging from 1.9 GeV/$c$ to 2.4 GeV/$c$ and a common upper
bound of 2.6 GeV/$c$, as measured in the centre of mass frame. The results are
based on a sample of 29 million $B\bar{B}$ pairs, accumulated by the Belle
detector at the KEKB asymmetric $e^+e^-$ collider operating on the
$\Upsilon(4S)$ resonance. In the momentum interval ranging from 1.9 GeV/$c$ to
2.6 GeV/$c$ we measure the partial branching fraction $\Delta \mathcal{B}(B\to
X_u e \nu_e)=(8.47 \pm 0.37 \pm 1.53)\times 10^{-4}$, where the first error is
statistical and the second is systematic. A prediction of the partial rate
$R=(21.69 \pm 3.62^{+ 2.18}_{- 1.98}) |V_{ub}|^2 \mathrm{ps}^{-1}$ in this
momentum interval based on theory is calculated with input HQET parameters that
have been derived from Belle's measurement of the $B\to X_s\gamma$ photon
energy spectrum, where the first error is due to the uncertainty on HQET
parameters and the second error is from theory. Using both $\Delta
\mathcal{B}(B\to X_u e \nu_e)$ and $R$ we find $|V_{ub}|=(5.08 \pm 0.47 \pm
0.42^{+ 0.26}_{- 0.23})\times 10^{-3}$, where the first error is from the
partial branching fraction, and the second and third errors are from
uncertainties in $R$.


title: Search for b->u transitions in B- -> D0 K- and B- -> D*0 K-

abstract:
  We search for B- ==> \tilde{D0}K- and B- ==> \tilde{D*0}K-, with \tilde{D*0}
==> \tilde{D0}pi0 or \tilde{D*0} ==> \tilde{D0}gamma, and \tilde{D0} ==> K+pi-
(and charge conjugates). These final states can be reached through the b==>c
transition B- ==> D0(*)K- followed by the doubly CKM-suppressed D0 ==> K+pi-,
or the b==>u transition B- ==> D0bar(*)K- followed by the CKM-favored D0bar ==>
K+pi-. The interference of these two amplitudes is sensitive to the angle gamma
of the unitarity triangle. Our results are based on 232 million
Upsilon(4S)==>BBbar decays collected with the BaBar detector at SLAC. We find
no significant evidence for these decays. We set a limit r_B = |A(B- ==> D0bar
K-)/A(B- ==> D0 K-)| < 0.23 at 90% C.L. using the most conservative assumptions
on the values of the CKM angle gamma and the strong phases in the B and D decay
amplitudes. In the case of the D* we set a 90% C.L. limit r*_B^2 = |A(B- ==>
D*0bar K-)/A(B- ==> D*0 K-)|^2 < (0.16)^2 which is independent of assumptions
on gamma and strong phases.

K_s^0 and Lambda^0 Production Studies in pbar-p Collisions at
  sqrt(s)=1800 and 630 GeV

abstract:
  We present a study of the production of K_s^0 and Lambda^0 in inelastic
pbar-p collisions at sqrt(s)= 1800 and 630 GeV using data collected by the CDF
experiment at the Fermilab Tevatron. Analyses of K_s^0 and Lambda^0
multiplicity and transverse momentum distributions, as well as of the
dependencies of the average number and <p_T> of K_s^0 and Lambda^0 on charged
particle multiplicity are reported. Systematic comparisons are performed for
the full sample of inelastic collisions, and for the low and high momentum
transfer subsamples, at the two energies. The p_T distributions extend above 8
GeV/c, showing a <p_T> higher than previous measurements. The dependence of the
mean K_s^0(Lambda^0) p_T on the charged particle multiplicity for the three
samples shows a behavior analogous to that of charged primary tracks.


title: Precision Measurement of the Weak Mixing Angle in Moller Scattering

abstract:
  We report on a precision measurement of the parity-violating asymmetry in
fixed target electron-electron (Moller) scattering: A_PV = -131 +/- 14 (stat.)
+/- 10 (syst.) parts per billion, leading to the determination of the weak
mixing angle \sin^2\theta_W^eff = 0.2397 +/- 0.0010 (stat.) +/- 0.0008 (syst.),
evaluated at Q^2 = 0.026 GeV^2. Combining this result with the measurements of
\sin^2\theta_W^eff at the Z^0 pole, the running of the weak mixing angle is
observed with over 6 sigma significance. The measurement sets constraints on
new physics effects at the TeV scale.

title:
Measurement of the Cross Section for $t\bar{t}$ Production in $p\bar{p}$
  Collisions using the Kinematics of Lepton+Jets Events

abstract:
  We present a measurement of the top pair production cross section in
$p\bar{p}$ collisions at $\sqrt{s}$=1.96 TeV. We collect a data sample with an
integrated luminosity of 194$\pm$11 pb$^{-1}$ with the CDF II detector at the
Fermilab Tevatron. We use an artificial neural network technique to
discriminate between top pair production and background processes in a sample
of 519 lepton+jets events, which have one isolated energetic charged lepton,
large missing transverse energy and at least three energetic jets. We measure
the top pair production cross section to be $\sigma_{t\bar{t}}= 6.6$$\pm 1.1
\pm 1.5$ pb, where the first uncertainty is statistical and the second is
systematic.


title: Neutral-Current Four-Fermion Production in e+e- Interactions at LEP

abstract:
  Neutral-current four-fermion production, e+e- -> ffff is studied in 0.7/fb of
data collected with the L3 detector at LEP at centre-of-mass energies
root(s)=183-209GeV. Four final states are considered: qqvv, qqll, llll and
llvv, where l denotes either an electron or a muon. Their cross sections are
measured and found to agree with the Standard Model predictions. In addition,
the e+e- -> Zgamma* -> ffff process is studied and its total cross section at
the average centre-of-mass energy 196.6GeV is found to be 0.29 +/- 0.05 +/-
0.03 pb, where the first uncertainty is statistical and the second systematic,
in agreement with the Standard Model prediction of 0.22 pb. Finally, the mass
spectra of the qqll final states are analysed to search for the possible
production of a new neutral heavy particle, for which no evidence is found.


title: Observation of the Decay Xi^0 --> Sigma^+ mu^- nu(bar)

abstract:
  The Xi^0 muon semi-leptonic decay has been observed for the first time with
nine identified events using the KTeV beam line and detector at Fermilab. The
decay is normalized to the Xi^0 beta decay mode and yields a value for the
ratio of decay rates of $(1.8^{+0.7}_{-0.5}(stat.)\pm0.2(syst.))\times
10^{-2}$. This is in agreement with the SU(3) flavor symmetric quark model.


title: A Measurement of the Ds+ Lifetime

abstract:
  A high statistics measurement of the Ds+ lifetime from the Fermilab
fixed-target FOCUS photoproduction experiment is presented. We describe the
analysis of the two decay modes, Ds+ -> phi(1020)pi+ and Ds+ ->
\bar{K}*(892)0K+, used for the measurement. The measured lifetime is 507.4 +/-
5.5 (stat.) +/- 5.1 (syst.) fs using 8961 +/- 105 Ds+ -> phi(1020)pi+ and 4680
+/- 90 Ds+ -> \bar{K}*(892)0K+ decays. This is a significant improvement over
the present world average.


title: Deeply virtual and exclusive electroproduction of omega mesons

abstract:
  The exclusive omega electroproduction off the proton was studied in a large
kinematical domain above the nucleon resonance region and for the highest
possible photon virtuality (Q2) with the 5.75 GeV beam at CEBAF and the CLAS
spectrometer. Cross sections were measured up to large values of the
four-momentum transfer (-t < 2.7 GeV2) to the proton. The contributions of the
interference terms sigma_TT and sigma_TL to the cross sections, as well as an
analysis of the omega spin density matrix, indicate that helicity is not
conserved in this process. The t-channel pi0 exchange, or more generally the
exchange of the associated Regge trajectory, seems to dominate the reaction
gamma* p -> omega p, even for Q2 as large as 5 GeV2. Contributions of handbag
diagrams, related to Generalized Parton Distributions in the nucleon, are
therefore difficult to extract for this process. Remarkably, the high-t
behaviour of the cross sections is nearly Q2-independent, which may be
interpreted as a coupling of the photon to a point-like object in this
kinematical limit.


title:
Measurement of the ttbar Production Cross Section in ppbar Collisions at
  sqrt(s)=1.96 TeV using Lepton + Jets Events with Lifetime b-tagging

abstract:
  We present a measurement of the top quark pair ($t\bar{t}$) production cross
section ($\sigma_{t\bar{t}}$) in $p\bar{p}$ collisions at $\sqrt{s}=1.96$ TeV
using 230 pb$^{-1}$ of data collected by the D0 experiment at the Fermilab
Tevatron Collider. We select events with one charged lepton (electron or muon),
missing transverse energy, and jets in the final state. We employ
lifetime-based b-jet identification techniques to further enhance the
$t\bar{t}$ purity of the selected sample. For a top quark mass of 175 GeV, we
measure $\sigma_{t\bar{t}}=8.6^{+1.6}_{-1.5}(stat.+syst.)\pm 0.6(lumi.)$ pb, in
agreement with the standard model expectation.


title:
First Measurement of the Ratio of Branching Fractions BR(LAMBDAB to
  Lambdac Mu Nu)/BR(LAMBDAB to Lambdac Pi) at CDF II

abstract:
  We present the first measurement of the ratio of branching fractions
BR(LAMBDAB TO LAMBDAC MU NU)/BR(LAMBDAB to LAMBDAC PI) based on 171.5 pb-1 of
ppbar collisions at the center of mass energy 1.96 TeV taken with the CDF-II
detector. In addition, we present measurements of BR(B0 TO DSTAR MU NU)/BR(B0
TO DSTAR PI) and BR(B0 TO D MU NU)/BR(B0 TO D PI), which serve as control
samples to understand the data and Monte Carlo used for the Lambdab analysis.
We find the relative branching fractions of the control samples are consistent
with the ratios obtained by the Particle Data Group at the 0.7 and 1.1 sigma
level, respectively. Finally, we obtain the relative Lambdab branching fraction
to be: BR(LAMBDAB TO LAMBDAC MU NU)/BR(LAMBDAB to LAMBDAC PI)=20.0 +- 3.0
(stat) +- 1.2 (syst) + 0.7 -2.1 (BR) +- 0.5 (UBR). The uncertainties of the
three relative branching fractions are from statistics, CDF internal
systematics, external measured branching ratios and unmeasured branching
ratios, respectively. We present a method to derive BR(LAMBDAB TO LAMBDAC PI)
using previous CDF measurements and obtain BR(LAMBDAB TO LAMBDAC PI) = (0.41 +-
0.19 (stat + syst) + 0.06 -0.08 (pt))%, where the last uncertainty is due to
the measured Lambdab pt spectrum. Combining with our result, we determine the
exclusive semileptonic branching fraction for the Lambdab= (8.1 +- 1.2 (stat) +
1.1 -1.6 (syst) +- 4.3 (BR(LAMBDAB TO LAMDAC PI)))%


title:
A Search for New Physics with High Mass Tau Pairs in PPbar Collisions at
  sqrt(s)=1.96 TeV at CDF

abstract:
  We present the results of a search for new particles decaying to tau pairs
using the data corresponding to an integrated luminosity of 195 pb^-1 collected
from March 2002 to September 2003 with the CDF detector at the Tevatron.
Hypothetical particles, such as Zprime and MSSM Higgs bosons can potentially
produce the tau pair final state. We discuss the method of tau identification,
and show the signal acceptance versus new particle mass. The low-mass region,
dominated by Z -> tau tau, is used as a control region. In the high-mass
region, we expect 2.8 +/- 0.5 events from known background sources, and observe
4 events in the data sample. Thus no significant excess is observed, and we set
upper limits on the cross section times branching ratio as a function of the
masses of heavy scalar and vector particles.


title:
Measurement of low energy longitudinal polarised positron beams via a
  Bhabha polarimeter

abstract:
  The introduction of a longitudinal polarised positron beam in an $e^+e^-$
linear collider calls for its polarisation monitoring and measurement at low
energies near its production location. Here it is shown that a relatively
simple Bhabha scattering polarimeter allows, at energies below 5000 MeV, a more
than adequate positron beam longitudinal polarisation measurement by using only
the final state electrons. It is further shown that out of the three, 10, 250
or 5000 MeV positron beam energy locations, where the polarisationmeasurement
in the TESLA linear collider can be performed, the 250 MeV site is best suited
for this task.


title: SUSY Searches at LEP

abstract:
  Searches for SUSY particles have been performed in 3.6 fb$^{-1}$ e$^+$e$^-$
data collected by the LEP detectors at $\sqrt{s}$ between 90 GeV and 209 GeV.
This talk reviews some of the relevant searches for SUSY particles at LEP. No
excess of events is observed in any channel. Results are interpreted in the
context of the MSSM.


title: Experimental Status of Beyond the Standard Model Collider Searches

abstract:
  This is a brief review of experimental strategies for physics beyond the
Standard Model based on the talk given in the ``Physics at LHC'' in Vienna,
July 2004 \cite{vienna}. The emphasis is on Tevatron thematology and
experience.


title: Study of the tau- --> 3h-2h+nu Decay

abstract:
  The branching fraction of the tau- --> 3h- 2h+ nu decay (h= pi, kaon) is
measured with the BaBar detector to be (8.56 +/- 0.05 +/- 0.42)E-04 where the
first error is statistical and the second systematic. The observed structure of
this decay is significantly different from the phase space prediction, with the
rho resonance playing a strong role. The decay tau- --> f1 pi nu with the f1
meson decaying to four charged pions, is observed and the branching fraction is
measured to be (3.9 +/- 0.7 +/- 0.5)E-04.


title: The COMPASS spin physics program

abstract:
  One of the main aims of the COMPASS experiment at CERN is the study of the
spin structure of the nucleon and in particular the determination of the gluon
polarization in the nucleon. We present some new results of 2002-2003 data
analysis. They concern a precise measurement of the deuteron structure function
g1 at small x, some preliminary result on Collins and Sivers asymmetries which
are linked to transversity and a new measurement of DeltaG/G.


title: A precision determination of the mass of the $\eta$ meson

abstract:
  Several processes of meson production in proton-deuteron collisions have been
measured simultaneously using a calibrated magnetic spectrograph. Among these
processes, the $\eta$ meson is seen clearly as a sharp missing--mass peak on a
slowly varying background in the $p+d\to ^3\textrm{He} +X$ reaction. Knowing
the kinematics of the other reactions with well determined masses, it is
possible to deduce a precise mass for the $\eta$ meson. The final result,
$m(\eta)=547.311\pm 0.028 \textrm{(stat)} \pm 0.032 \textrm{(syst) MeV/c}^2$,
is significantly lower than that found by the recent NA48 measurement, though
it is consistent with values obtained in earlier counter experiments.


title:
A Search for the Singlet-P State hc(1 1P1) of Charmonium in
  Proton-Antiproton Annihilations at Fermilab Experiment E835p

abstract:
  We present the results of a search for the spin-singlet P-wave state hc(1
1P1) of charmonium formed through proton-antiproton annihilation at Fermilab
experiment E835. The decay channels whjich were studied were ppbar -> J/psi + X
-> e^+e^- + X, ppbar -> J/psi + pi0 -> e^+e^- + 2gamma, ppbar -> J/psi + pi0pi0
-> e^+e^- + 4gamma, and the neutral channel ppbar -> eta_c gamma -> (2gamma)
gamma. The decay ppbar -> J/psi gamma -> e^+e^- gamma, into which 1P1 decay is
forbidden by C-parity conservation, was also examined for comparison
  The 90% confidence upper limits for the decay channels studied in the mass
range 3525.1-3527.3 MeV for a 1P1 resonance with a presumed width of 1.0 MeV
were determined to be B(ppbar->1P1)xB(1P1->J/psi+X) <= 1.8x10^-7,
B(ppbar->1P1)xB(1P1->J/psi+pi0) <= 1.2x10^-7, and
B(ppbar->1P1)xB(1P1->J/psi+gamma) <= 1.0x10^-7. No evidence for a 1P1
enhancement was observed in either of the two additional reactions studied.


title:
Measurement of inelastic J/psi production in deep inelastic scattering
  at HERA

abstract:
  The inelastic production of J/psi mesons in e p collisions has been studied
with the ZEUS detector at HERA using an integrated luminosity of 109 pb-1. The
J/psi mesons were identified using the decay channel J/psi -> mu+ mu-. The
measurements were performed in the kinematic range 2 < Q^2< 80 Gev^2, 50 < W <
250 Gev, 0.2 < z <0.9 and -1.6 < Ylab < 1.3, where Q^2 is the virtuality of the
exchanged photon, W is the photon-proton centre-of-mass energy, z is the
fraction of the photon energy carried by the J/psi meson in the proton rest
frame and Ylab is the rapidity of the J/psi in the laboratory frame. The
measured cross sections are compared to theoretical predictions within the
non-relativistic QCD framework including colour-singlet and colour-octet
contributions, as well as to predictions based on the kT-factorisation
approach. Calculations of the colour-singlet process generally agree with the
data, whereas inclusion of colour-octet terms spoils this agreement.


title: Electroweak Physics at LEP2

abstract:
  The measurements resulting from the analysis of the LEP2 data have brought
more strong evidence in support of the standard electroweak model. In
particular the LEP2 data has revealed (i) the first determination of the SU(2)
gauge bosons self-couplings, (ii) the first direct measurements of the W
decay-couplings, and (iii) the current best direct measurement of the W mass.


title:
Observation of Parity Violation in the Omega-minus -> Lambda + K-minus
  Decay

abstract:
  The alpha decay parameter in the process Omega-minus -> Lambda + K-minus has
been measured from a sample of 4.50 million unpolarized Omega-minus decays
recorded by the HyperCP (E871) experiment at Fermilab and found to be [1.78 +/-
0.19(stat) +/- 0.16(syst)]{\times}10^{-2}. This is the first unambiguous
evidence for a nonzero alpha decay parameter, and hence parity violation, in
the Omega-minus -> Lambda + K-minus decay.


title: First observation of the decay K+ -> e+ nu mu+ mu-

abstract:
  Experiment 865 at the Brookhaven AGS has observed the decay K^+ -> e^+ nu
mu^+ mu^-. The branching ratio extracted is (1.72 +/- 0.37(stat) +/- 0.17(syst)
+/- 0.19(model)) x 10^{-8} where the third term in the error results from the
use of a model to extrapolate into a kinematic region dominated by background.


title:
A direct search for the CP-violating decay Ks->3p^0 with the KLOE
  detector at DAFNE

abstract:
  We have searched for the decay Ks->3p^0 with the KLOE experiment at DAFNE
using data from e^+ e^- collisions at a center of mass energy W= m(phi) for an
integrated luminosity L=450 pb^-1. The search has been performed with a pure Ks
beam obtained by tagging with Kl interactions in the calorimeter and detecting
six photons. We find an upper limit for the branching ratio of 1.2x10^-7 at 90%
C.L.


title:
Study of Jet Shapes in Inclusive Jet Production in ppbar Collisions at
  sqrt{s} = 1.96 TeV

abstract:
  We report on a study of jet shapes in inclusive jet production in $p \bar{p}$
collisions at $\sqrt{s} = 1.96 {\rm TeV}$ using the upgraded Collider Detector
at Fermilab in Run II (CDF II) based on an integrated luminosity of $170 \rm
pb^{-1}$. Measurements are carried out on jets with rapidity $0.1 < |Y^{\rm
jet}| < 0.7$ and transverse momentum 37 GeV/c $< P_T^{\rm jet} < 380$ GeV/c.
The jets have been corrected to the hadron level. The measured jet shapes are
compared to leading-order QCD parton-shower Monte Carlo predictions as
implemented in the PYTHIA and HERWIG programs. PYTHIA, tuned to describe the
underlying event as measured in CDF Run I, provides a better description of the
measured jet shapes than does PYTHIA or HERWIG with their default parameters.


title:
CP violation in a light Higgs boson decay from tau-spin correlations at
  a linear collider

abstract:
  We present a new method to measure the transverse spin correlation in the
$H\to\tau^+\tau^-$ decay. The method has been devised to be insensitive to the
beamstrahlung which affects the definition of the beam energy at a linear
collider. In the case of two $\tau\to\pi^\nu$ decays, using the anticipated
detector performance of the TESLA project, we get a promising estimation of the
error expected on the measurement of a CP violating phase.


title: B Lifetimes and Mixing at the Tevatron

abstract:
  We present recent results on b-hadron lifetimes and mixing obtained from the
analysis of the data collected at the Tevatron Collider by the CDF and D0
Collaborations in the period 2002 - 2004. Many lifetime measurements have been
updated since the Summer 2004 conferences, sometimes improving significantly
the accuracy. Likewise the measurement of the $B_d$ oscillation frequency has
been updated. New limits on the $B_s$ oscillation frequency have been
determined using for the first time Run II data.


title: Recent HERMES Results on DVCS

abstract:
  The interference of Deeply Virtual Compton Scattering (DVCS) and
Bremsstrahlung leads to a beam-charge asymmetry that can be observed for
exclusive photon production in the collision of high energy leptons and
nucleons/nuclei. Recent results for a hydrogen and a deuterium target are
reported and a consistent tendency for a rise of the cosine phi coefficient
with momentum transfer |t| has been found.


title: Charge Asymmetry of Same-Sign Dileptons in $B^0$-$\bar{B}^0$ Mixing

abstract:
  We report a measurement of the charge asymmetry for same-sign dileptons in
$B^0$-$\bar{B}^0$ mixing, $A_{\rm sl}$. The data were collected with the Belle
detector at KEKB. Using a data sample of 78 fb$^{-1}$ recorded at the
$\Upsilon(4S)$ resonance and 9 fb$^{-1}$ recorded at an energy 60 MeV below the
resonance, we measure $A_{\rm sl} = (-1.1 \pm 7.9(\text{stat}) \pm
7.0(\text{sys}))\times 10^{-3}$.


title:
Search for Randall-Sundrum Gravitons in Dilepton and Diphoton Final
  States

abstract:
  We report the first direct search for the Kaluza-Klein (KK) modes of
Randall-Sundrum gravitons using dielectron, dimuon, and diphoton events
observed with the D0 detector operating at the Fermilab Tevatron ppbar Collider
at sqrt(s) = 1.96 TeV. No evidence for resonant production of gravitons has
been found in the data corresponding to an integrated luminosity of
approximately 260 pb^-1. Lower limits on the mass of the first KK mode at the
95% C.L. have been set between 250 and 785 GeV, depending on its coupling to SM
particles.


title: Recent Results from K2K Experiment

abstract:
  The latest results from K2K experiment are reported, with focus on muon
neutrino oscillation. The results are based on data taken from June 1999 to
February 2004, corresponding to 8.9 x 10^19 protons on target.


title:
Can One Extract the Neutrino Oscillation Signature from the
  SuperKamiokande Experiment ? An Analysis of Neutrino Events Occurring outside
  the Detector

abstract:
  The SuperKamiokande group assert that they have found an oscillatory
signature in atmospheric neutrinos through the analysis of \textit{Fully
Contained Events} and \textit{Partially Contained Events}. We have performed an
$L/E$ (length/energy) analysis of \textit{Upward Through-Going Muon Events} and
\textit{Stopping Muon Events} in a numerical computer simulations both with and
without neutrino oscillations but were unable to find an oscillatory signature.
We give likely explanations for the absence of the oscillatory signature in our
simulations and its apparent presence in the SuperKamiokande data.


title: Physics of the Muon Spectrometer of the ALICE Experiment

abstract:
  The main goal of the Muon spectrometer of the ALICE experiment at LHC is the
measurement of heavy quark production in p+p, p+A and A+A collisions at LHC
energies, via the muonic channel. Physics motivations and expected performances
have been presented in this talk.


title: Prospects to measure the Higgs boson properties in ATLAS

abstract:
  As soon as a significant signal in one of the Higgs boson discovery channels
is observed, it will be important to establish its nature. To do this, a
precise measurements of its properties is important. In this article the
prospects to measure the Higgs boson mass, width, spin and CP-quantum numbers,
couplings to the known Standard Model particles and self-couplings by the ATLAS
experiment are summarized.


title: Electroweak Measurements At Tevatron

abstract:
  Recent Run 2 experimental results on electroweak physics from the CDF and D0
collaborations at Tevatron are reviewed. We present measurements of the
inclusive W and Z boson cross-sections times leptonic branching ratio as well
as the Z/gamma forward-backward asymmetry and the W charge asymmetry for p-pbar
collisions at sqrt{s}=1.96 TeV. The first Run 2 studies for the W width and W
mass measurements are also reported. The di-boson production results are
presented elsewhere.


title:
Spin Effects in Forward pi^0-production in Polarized Proton-Proton
  Collisions at STAR

abstract:
  We report some results in large pseudo rapidity pi^0-production in polarized
proton collisions at 200 GeV center of mass energy. The single spin asymmetry
for positive Feynman x (x_F) is consistent with zero up to ~0.35, then
increases with increasing x_F. This behavior can be described by
phenomenological models including the Sivers effect, Collins effect or twist-3
contributions in initial and final states. The asymmetry is found to be zero
for negative x_F (-0.6<x_F<-0.2). It has been observed that inclusive
p+p->pi^0+X cross sections at \eta=3.3, 3.8 and 4.0 are consistent with
next-to-leading order perturbative QCD calculations.


title: Search for the Lepton-Number-Violating Decay $\Xi^- \to p \mu^- \mu^-$

abstract:
  A sensitive search for the lepton-number-violating decay $\Xi^-\to p
\mu^-\mu^-$ has been performed using a sample of $\sim10^9$ $\Xi^-$ hyperons
produced in 800 GeV/$c$ $p$-Cu collisions. We obtain $\mathcal{B}(\Xi^-\to p
\mu^-\mu^-)< 4.0\times 10^{-8}$ at 90% confidence, improving on the best
previous limit by four orders of magnitude.


title: New QCD tests with old JADE data

abstract:
  Data from e+e- annihilation into hadrons collected by the JADE experiment at
centre-of-mass energies between 14 and 44 GeV were used to study the 4-jet rate
using the Durham algorithm as well as the first five moments of event shape
observables. The data were compared with NLO QCD predictions, augmented by
resummed NLLA calculations for the 4-jet rate, in order to extract values of
the strong coupling constant alpha_S. The preliminary results are alpha_S(M_Z)
= 0.1169 +/- 0.0026 (4-jet rate) and alpha_S(M_Z) = 0.1286 +/- 0.0072 (moments)
consistent with the world average value. For some of the higher moments
systematic deficiencies of the QCD predictions are observed.


title:
Searches for the Higgs boson in Minimal Supersymmetric CP-conserving and
  CP-violating Standard Model scenarios at LEP

abstract:
  It is important to study extended models containing more than one physical
Higgs boson in the spectrum. In particular, Two Higgs Doublet Models (2HDMs)
are attractive extensions of the SM, predicting new phenomena with the fewest
new parameters. The Higgs sector in the Minimal Supersymmetric extension of the
SM (MSSM) is a 2HDM itself. The neutral Higgs searches performed at LEP are
showing no evidence of the presence of a signal and have therefore been
interpreted in the context of 2HDMs. Depending on the model considered
exclusion of large regions of the parameter space can be obtained, but the
existence of the lightest Higgs boson with masses lower than 90 GeV is not
ruled out in all models by LEP. In the MSSM at least one of the neutral Higgs
bosons is predicted to have its mass close to the electroweak energy scale;
when radiative corrections are included, this mass should be less than about
140 GeV. This prediction provides a strong motivation for searches at present
and future colliders.


title: PHENIX Spin Program, Recent Results

abstract:
  Acceleration of polarized protons in the Relativistic Heavy Ion Collider
(RHIC) provides a unique tool to study the spin structure of the nucleon. We
give a brief overview of the PHENIX program to investigate the unknown gluon
and flavor decomposed sea quark polarization in the proton, utilizing polarized
proton collisions at RHIC. We report first results from the PHENIX experiment
on transverse single-spin asymmetry in pi0 and charged hadron production and
longitudinal double-spin asymmetry in pi0 production, at mid-rapidity.


title: Diboson Cross Sections at sqrt(s) = 1.96 TeV

abstract:
  A brief survey of the results on diboson production at the Tevatron is
presented. Measured cross sections for $W\gamma$, $Z\gamma$, $WW$, and limits
on WZ/ZZ are summarized.


title: Lepton Flavor Violation at LHC

abstract:
  Lepton flavor violation (LFV) within the realm of the Standard Model is
forbidden. However recent neutrino experiments strongly suggest neutrino
oscillations, giving way to LFV. Beyond SM theories, such as supersymmetry and
supergravity also allow LFV. This note reviews the possibility of observing LFV
signal in the two general purpose LHC experiments: ATLAS and CMS. It is shown
that using the initial LHC luminosity, in about a year, either a discovery can
be made or the current LFV limits can be enhanced by an order of magnitude.


title: Search for right-handed W bosons in top quark decay

abstract:
  We present a measurement of the fraction f+ of right-handed W bosons produced
in top quark decays, based on a candidate sample of $t\bar{t}$ events in the
lepton+jets decay mode. These data correspond to an integrated luminosity of
230pb^-1, collected by the DO detector at the Fermilab Tevatron $p\bar{p}$
Collider at sqrt(s)=1.96 TeV. We use a constrained fit to reconstruct the
kinematics of the $t\bar{t}$ and decay products, which allows for the
measurement of the leptonic decay angle $\theta^*$ for each event. By comparing
the $\cos\theta^*$ distribution from the data with those for the expected
background and signal for various values of f+, we find
f+=0.00+-0.13(stat)+-0.07(syst). This measurement is consistent with the
standard model prediction of f+=3.6x10^-4.


title: Measurement of the pion pion scattering length

abstract:
  We report here the measurment of the pion pion scattering length from a study
of the kaon to 3 pions dalitz plot.


title:
Measurement of the W mass at LEP and recent Results of the Electroweak
  Fit

abstract:
  The measurement of the mass of the W boson, m_W, by direct reconstruction is
described. The combination of all measurements of the four LEP experiments
yields m_W = 80.412 +- 0.042 GeV. Together with several other measurements the
extracted m_W value enters the electroweak fit, which tests the Standard Model
(SM) predictions and extracts SM parameters which have not yet been measured.
The latest results of the fit are presented.


title:
The Discovery Potential of Supersymmetry at CMS within the mSUGRA Model
  Using Same-Sign Di-Muons

abstract:
  A detailed study of the same-sign muon signature within the mSUGRA model is
described. Selection criteria based on the missing transverse energy in the
events and the jet and muon transverse momenta are applied. The results
indicate that an excess of SUSY events over the Standard Model background
processes can be statistically significant for an integrated luminosity of less
than 10 fb^-1 for many benchmark points with m_1/2 up to 650 GeV/c^2.


title:
Measurements of Hadronic, Semileptonic and Leptonic Decays of D Mesons

title: Beauty production cross section measurements at Ecm=1.96 TeV

abstract:
  The RunII physics program at the Tevatron started in spring 2001 with protons
and antiprotons colliding at an energy of $\sqrt{s}$=1.96 TeV, and it is
carrying on with more than 500 pb-1 of data as collected by both the CDF and D0
experiments. Recent results on beauty production cross section measurements are
here reported.


title:
Evidence for X(3872)-->gamma J/psi and the sub-threshold decay
  X(3872)-->omega J/psi

abstract:
  We report evidence for the decay modes X(3872) --> gamma J/psi and X(3872)-->
pi+pi-pi0 J/psip. In the latter, the pi+pi-pi0 invariant mass distribution has
a strong peak between 750 MeV and the kinematic limit of 775 MeV, suggesting
that the process is dominated by the sub-threshold decay X --> omega J/psi.
These results establish the charge-conjugation parity of the X(3872) as C=+1.
The results are based on a study of X(3872) mesons produced via exclusive B -->
K X(3872) decays in a 256 fb-1 data sample collected at the Upsilon(4S)
resonance in the Belle detector at the KEKB collider. The X(3872) --> gamma
J/psi signal and the pi+pi-pi0 J/psi signal each has a statistical significance
that is greater than 4 sigma.


title:
Experimental constraints on the possible J^PC quantum numbers of the
  X(3872)

abstract:
  We examine possible J^PC quantum number assignments for the X(3872). Angular
correlations between final state particles in X(3872) --> pi+pi- J/psi decays
are used to rule out J^PC values of 0++ and 0-+. The shape of the pi+pi- mass
distribution near its upper kinematic limit favors S-wave over P-wave as the
relative orbital angular momentum between the final-state dipion and J/psi,
which strongly disfavors 1-+ and 2-+ assignments. The accumulated evidence
strongly favors a J^PC = 1++ assignment for the X(3872), although the 2++
possibility is not ruled out by tests reported here. The analysis is based on a
sample of X(3872) mesons produced via the exclusive process B --> K X(3872) in
a 256 fb-1 data sample collected at the Upsilon(4S) resonance in the Belle
detector at the KEKB collider.


title:
Measurements of Branching Fraction and Polarization in B^+ -> rho^+
  K^{*0} Decay

abstract:
  We present the results of a study of the charmless vector-vector decay
$B^+\to \rho^+K^{*0}$, based on 253 fb$^{-1}$ of data collected with the Belle
detector at the KEKB asymmetric-energy $e^+e^-$ collider. We obtain the
branching fraction ${\cal B}(B^+\to\rho^+ K^{*0})=(8.9\pm 1.7(\rm stat)\pm 1.2
(\rm syst))\times 10^{-6}$. We also perform a helicity analysis of the $\rho$
and $K^*$ vector mesons, and obtain the longitudinal polarization fraction
$f_L(B^+\to \rho^+ K^{*0})=0.43 \pm 0.11(\rm stat)^{+0.05}_{-0.02}(\rm syst)$.


title: Running of the QED coupling in small-angle Bhabha scattering at LEP

abstract:
  Using the OPAL detector at LEP, the running of the effective QED coupling
alpha(t) is measured for space-like momentum transfer, 2 \leq -t \leq 6 GeV^2,
from the angular distribution of small-angle Bhabha scattering. This is
currently the most significant direct observation of the running of the QED
coupling in a single experiment and the first clear evidence of the hadronic
contribution to the running in the space-like region. Our result is in good
agreement with standard evaluations of alpha(t), based on data in the time-like
region.


title: Recent $J/\psi$ Results from Bes II

abstract:
  Multiquark searches have been a hot topic in recent years. Some threshold
enhancements were observed during the analysis of 58M $\jpsi$ events collected
by BES II detector. These enhancements can't be explained by the standard model
and may be candidates of multiquark. BES also contribute a lot to the study of
light scalar mesons, such as $\sigma$,$\kappa$,$f_{0}(1370)$ and $f_{0}(1710)$
etc. Study of the excited baryon states and measurements of some $\jpsi$ decays
are also done with the $\jpsi$ events of BES.


title:
Subleading-twist effects in single-spin asymmetries in semi-inclusive
  deep-inelastic scattering on a longitudinally polarized hydrogen target

abstract:
  Single-spin asymmetries in the semi-inclusive production of charged pions in
deep-inelastic scattering from transversely and longitudinally polarized proton
targets are combined to evaluate the subleading-twist contribution to the
longitudinal case. This contribution is significantly positive for (\pi^+)
mesons and dominates the asymmetries on a longitudinally polarized target
previously measured by \hermes. The subleading-twist contribution for (\pi^-)
mesons is found to be small.


title: Bs Mixing, Lifetime Difference and Rare Decays at the Tevatron

abstract:
  Recent results on Bs mixing, lifetime difference and rare decays obtained by
the CDF and DO collaborations using the data samples collected at the Tevatron
Collider in the period 2002 - 2005 are presented.

abstract:
  Recent results on $\psip$ decays, including 10 Vector + Pseudoscalar (VP)
modes and $p\bar{p}\pi^0(\eta)$, are reported with $14\times10^6$ $\psip$
events collected with the BESII detector. Cross sections and form factors for
$e^+e^- \to \wpi$, $\rho\eta$, and $\rho\etap$ at the center of mass energies
of 3.650, 3.686, and 3.773 GeV are measured simultaneously.

(DBD0n) of 130Te.It consists of an array of 62 TeO2 crystals with a total mass

test for the feasibility of the next generation experiment CUORE, ~ 750 kg of
TeO2 bolometric mass.In this paper last results from CUORICINO and prospects
for the future CUORE.


title: Di-Photon and Photon+b/c Production Cross Sections at Ecm=1.96 TeV

abstract:
  Measurements of the di-photon cross section have been made in the central
region and are found to be in good agreement with NLO QCD predictions. The
cross section of events containing a photon and additional heavy flavour jet
have also been measured, as well as the ratio of photon+b to photon+c. The
statistically limited sample shows good agreement with Leading Order
predictions.

  Study of Jet Properties at the Tevatron (Proceedings of the XIX Rencontres de
Physique de La Vallee d'Aoste)
  In this contribution, a number of new QCD results on jet production from the
CDF and D0 experiments in Run II are discussed in detail.


title: Dalitz Analysis of Three-Body B Decays

abstract:
  Results on Dalitz analysis of three-body charmless B+=>K+pi+pi- and
B+=>K+K+K- decays are reported. We also present preliminary results on the
studies of direct CP violation in three-body decay B+-=>K+-pi+pi-. The analysis
is performed using a large data sample collected with the Belle detector.


title:
Study of dimuon production in Indium-Indium collisions with the NA60
  experiment

abstract:
  The NA60 experiment at the CERN-SPS is devoted to the study of dimuon
production in heavy-ion and proton-nucleus collisions. We present preliminary
results from the analysis of Indium-Indium collisions at 158 GeV per nucleon.
The topics covered are low mass vector meson production, J/psi production and
suppression, and the feasibility of the open charm measurement from the dimuon
continuum in the mass range below the J/psi peak.


title: CLEO Results on Transitions in Heavy Quarkonia

abstract:
  Recent CLEO results on electromagnetic and hadronic transitions in charmonium
and bottomonium systems are reviewed.


title: Top Quark Pair Production at the Tevatron

abstract:
  The measurement of the top quark pair production cross section in
proton-antiproton collisions at 1.96 TeV is a test of quantum chromodynamics
and could potentially be sensitive to new physics beyond the standard model. I
report on the latest t-tbar cross section results from the CDF and DZero
experiments in various final state topologies which arise from decays of top
quark pairs.


title: Di-boson production at the Tevatron

abstract:
  We present some precision measurements on electroweak physics performed at
the Tevatron collider at Fermilab. Namely we report on the boson-pair
production cross sections and on triple gauge boson couplings using proton
anti-proton collisions collected by the CDF and D0 experiments at the
center-of-mass energy of 1.96 TeV. The data correspond to an integrated
luminosity of up to 324 pb-1.


title: SIMPLE Dark Matter Search Results

abstract:
  We report an improved SIMPLE experiment comprising four superheated droplet
detectors with a total exposure of 0.42 kgd. The result yields ~ factor 10
improvement in the previously-reported results, and -- despite the low exposure
-- is seen to provide restrictions on the allowed phase space of spin-dependent
coupling strengths almost equivalent to those from the significantly larger
exposure NAIADCDMS/ZEPLIN searches.


title: Antiproton--Proton Scattering Experiments with Polarization

abstract:
  The document describes the physics case of the PAX experiment using polarized
antiprotons, which has recently been proposed for the new Facility for
Antiprotons and Ions Research (FAIR) at GSI--Darmstadt. Polarized antiprotons
provide access to a wealth of single-- and double--spin observables, thereby
opening a new window to physics uniquely accessible at the HESR. The polarized
antiprotons would be most efficiently produced by spin--filtering in a
dedicated Antiproton Polarizer Ring (APR) using an internal polarized hydrogen
gas target. In the proposed collider scenario of the PAX experiment, polarized
protons stored in a COSY--like Cooler Storage Ring (CSR) up to momenta of 3.5
GeV/c are bombarded head--on with 15 GeV/c polarized antiprotons stored in the
HESR. This asymmetric double--polarized antiproton--proton collider is ideally
suited to map, e.g., the transversity distribution in the proton. The proposed
detector consists of a large--angle apparatus optimized for the detection of
Drell--Yan electron pairs.


title: Searches for the Standard Model Higgs Boson at the Tevatron

abstract:
  The CDF and D0 experiments at the Tevatron have searched for the Standard
Model Higgs boson in data collected between 2001 and 2004. Upper limits have
been placed on the production cross section times branching ratio to b-antib
pairs or WW pairs as a function of the Higgs boson mass. Projections indicate
that the Tevatron experiments have a chance of discovering a MH = 115 GeV Higgs
with the total dataset foreseen by 2009, or excluding it at 95% C.L. up to a
mass of 135 GeV.


title: Supersymmetry results at the Tevatron

abstract:
  The Run II physics programme of the Tevatron is proceeding with more than 300
pb-1 of analysis quality data, collected at a centre-of-mass energy of 1.96
TeV. Searches for supersymmetric particles are starting to set new limits,
improving over the LEP and Run I results and exploring new regions of parameter
space. We present recent results in Supersymmetry with the upgraded CDF and DO
detectors and give some prospects for the future of these searches.


title:
Branching Fraction Measurements of psi(2S) Decay to Baryon-Antibaryon
  Final States

abstract:
  Using 3.08 million psi(2S) decays observed in e^+e^- collisions by the CLEO
detector, we present the results of a study of the psi(2S) decaying into
baryon-antibaryon final states. We report the most precise measurements of the
following eight modes: proton-antiproton, lambda-antilambda, Xi^- antiXi^-,
Xi^0-antiXi^0 (first observation), Sigma+-antiSigma^+ (first observation), and
Sigma^0-antiSigma^0, and place upper limits for the modes, Xi^0*-antiXi^0* and
Omega^- antiOmega^-.


title: Exclusive Rho Rho Production in Tagged Gamma-Gamma Interactions at LEP

abstract:
  Exclusive rho rho production in two-photon collisions between a quasi-real,
gamma, and a virtual, gamma*, photons is studied at LEP at centre-of-mass
energies 89 GeV < sqrt{s} < 209 GeV with a total integrated luminosity of 854.7
pb-1. The cross sections of the gamma gamma* -> rho rho processes are
determined as a function of the photon virtuality, Q^2, and the two-photon
centre-of-mass energy, Wgg, in the kinematic region: 0.2 GeV^2 < Q^2 < 30 GeV^2
and 1.1 GeV < Wgg < 3 GeV.


title: New results from CLEO

abstract:
  We present recent results from the CLEO Collaboration. The data used were
collected from 1995 untill now at the Cornell Electron-positron Storage Ring
(CESR). Measurements of the leptonic branching fractions for $J/\psi \to e^+
e^-, \mu^+ \mu^-$ and $\Upsilon(1,2,3S) \to \mu^+ \mu^-$, search for
$D^0-\bar{D^0}$ mixing using time dependent Dalitz plot analyses of the decay
$D^0 \to K^0_S\pi^+\pi^-$, and search for the process $e^+e^- \to \Lambda_b
\bar{\Lambda_b}$ near threshold are discussed.


title: Searches for non-SM Higgs at Tevatron

abstract:
  We present the non-standard model Higgs boson searches at both DO and CDF
experiments. We concentrate on three topics, reported by DO and CDF recently:
the searches for the minimal supersymmetric Higgs boson using pp--> hbb -->
bbbb and pp --> hX --> tau tau X, and for long-lived doubly charged Higgs
boson.


title: Measurement of Deeply Virtual Compton Scattering at HERA

abstract:
  A measurement is presented of elastic deeply virtual Compton scattering
\gamma* p \to \gamma p made using e^+ p collision data corresponding to a
luminosity of 46.5 pb^{-1}, taken with the H1 detector at HERA. The cross
section is measured as a function of the photon virtuality, Q^2, the invariant
mass of the \gamma* p system, W, and for the first time, differentially in the
squared momentum transfer at the proton vertex, t, in the kinematic range 2 <
Q^2 < 80 GeV^2, 30 < W < 140 GeV and |t| < 1 GeV^2. QCD based calculations at
next-to-leading order using generalized parton distributions can describe the
data, as can colour dipole model predictions.


title: Forward Pion Production in p+p and d+Au Collisions at STAR

abstract:
  Measurements are reported of the production of high energy pi-zero mesons
from the STAR experiment in p+p and d+Au collisions at sqrt(s_NN)=200 GeV and
<eta>=4.00 (d beam direction). The inclusive yield agrees with perturbative QCD
calculations in p+p collisions, but is found to be reduced in d+Au collisions.
The azimuthal correlations of the forward pi-zero with charged hadrons at
midrapidity agree with PYTHIA in p+p collisions, but are suppressed in d+Au
collisions. The results are consistent with the conjecture that the gluon
density in nuclei is suppressed.


title:
Search for single top quark production in ppbar collisions at
  sqrt(s)=1.96 TeV

abstract:
  We present a search for electroweak production of single top quarks in the
s-channel and t-channel using neural networks for signal-background separation.
We have analyzed 230 pb$^{-1}$ of data collected with the D0 detector at the
Fermilab Tevatron Collider at a center-of-mass energy of 1.96 TeV and find no
evidence for a single top quark signal. The resulting 95% confidence level
upper limits on the single top quark production cross sections are 6.4 pb in
the s-channel and 5.0 pb in the t-channel.


title: W Boson Mass Measurement at the Tevatron

abstract:
  The W boson mass (mW) is a key parameter of the standard model, constraining
the mass of the unobserved Higgs boson. Using Tevatron ppbar collision data
from 1992-1996, the CDF and D0 collaborations measured mW to a precision of 59
MeV. The ongoing Tevatron Run 2 has produced a factor of 5 more collisions,
promising a significant reduction in the W mass uncertainty. CDF has analyzed
the first 200/pb of Run 2 data and determined the uncertainty on its W mass
measurement to be 76 MeV.
