title: Charmonia Production at the CERN/SPS

abstract:
  We present the final results of experiment NA50 on charmonia production in
Pb-Pb interactions at 158 A GeV. A strong increasing suppression is observed
with increasing centrality, for both the jpsi and psiprime resonances. We also
present new developments regarding the jpsi and psiprime normal nuclear
absorption determinations deduced from proton-nucleus data only. Their
comparison with Pb-Pb results allows us to conclude that the jpsi anomalous
suppression sets in at mid-centralities while the S-U results show a reasonable
agreement with the p-A behavior. The psiprime suffers a significantly stronger
suppression already in S-U interactions, which continuously increases in the
Pb-Pb system, and is completely incompatible with the expected behavior deduced
from p-A collisions.


title: Jet Measurements and Extraction of the Strong Coupling Constant at HERA

abstract:
  Results on jet measurements in neutral current deep inelastic scattering at
HERA are presented. The low-$x_{Bj}$ and low-$Q^2$ region is explicitly
investigated using forward jet production and the azimuthal asymmetry between
jets in dijet production. Recent results on the determination of the strong
coupling constant, $\alpha_s(M_Z)$, are discussed.


title: Search for new physics in B -> VV decays and other hot topics from Belle

abstract:
  We report studies in polarization in B decay into two vector mesons with data
equivalent to $253 {\rm fb^{-1}}$ on $\Upsilon(4S)$ resonance at KEKB. In $B^0
\to \phi K^{*0}$, $B^+ \to \phi K^{*+}$ and $B^+ \to \rho^+ K^{*0}$ decays, we
determine $f_L = 0.45 \pm 0.05({\rm stat.}) \pm 0.02({\rm syst.})$, $f_L = 0.52
\pm 0.08({\rm stat.}) \pm 0.03({\rm syst.})$ and $f_L = 0.43 \pm 0.11({\rm
stat.}) ^{+ 0.05}_{-0.02}({\rm syst.})$ respectively, where $f_L$ is a ratio
between longitudinal and transverse polarization, and a na\"{i}ve theoretical
estimation assumes $f_L \sim 1$. The discrepancy from 1 in $f_L$ may suggest
existence of new amplitude within or/and beyond the Standard Model.


title: Recent Results From CLEO-c

abstract:
  This paper describes recent preliminary results from the CLEO-c experiment
using an initial ~60 pb^-1 sample of data collected in e^+e^- collisions at a
center of mass energy around the mass of the psi(3770). A first measurement of
the branching fraction BR(D^+ -> mu^+ nu) = (3.5 +/- 1.4 +/- 0.6)x 10^-4 and
the corresponding decay constant f_D = (202 +/- 41 +/- 17) MeV has been made.
Several charged and neutral D meson absolute exclusive semileptonic branching
fractions have been measured, including first measurements of the branching
fractions BR(D^0 -> rho^-e^+ nu) = (0.19 +/- 0.04 +/- 0.02)% and BR(D^+ ->
omega e^+ nu) = (0.17 +/- 0.006 +/- 0.01)%. Estimated uncertainties for
inclusive D semileptonic decay modes are also presented. Fits to single and
double D tagged events are used to extract absolute branching fractions of
several hadronic D decay modes and DDbar production cross sections. Most of
these results from this small preliminary sample are already of greater
sensitivity than previously published results.


title:
Search for the decay K+ to pi+ gamma gamma in the pi+ momentum region
  P>213 MeV/c

abstract:
  We have searched for the K+ to pi+ gamma gamma decay in the kinematic region
with pi+ momentum close to the end point. No events were observed, and the 90%
confidence-level upper limit on the partial branching ratio was obtained, B(K+
to pi+ gamma gamma, P>213 MeV/c) < 8.3 x 10-9 under the assumption of chiral
perturbation theory including next-to-leading order ``unitarity'' corrections.
The same data were used to determine an upper limit on the K+ to pi+ gamma
branching ratio of 2.3 x 10-9 at the 90% confidence level.


title: Semileptonic B Decays and Determination of |Vub|

abstract:
  Semileptonic decays of the B mesons provide an excellent probe for the weak
and strong interactions of the bottom quark. The large data samples collected
at the B Factories have pushed the experimental studies of the semileptonic B
decays to a new height and stimulated significant theoretical developments. I
review recent progresses in this fast-evolving field, with an emphasis on the
determination of the magnitude of the Cabibbo-Kobayashi-Maskawa matrix element
|Vub|.


title: Results from the Salt Phase of SNO

abstract:
  The Sudbury Neutrino Observatory (SNO) has recently completed an analysis of
data from the salt phase of the experiment, in which NaCl was added to the
heavy-water neutrino target to enhance sensitivity to solar neutrinos. Results
from the 391-day salt data set are summarized, including the measured solar
neutrino fluxes, the electron energy spectrum from charged current
interactions, and the day-night neutrino flux asymmetries. Constraints on
neutrino mixing parameters including the new measurements are also given.


title:
Measurement of the 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 from the angular
distribution of small-angle Bhabha scattering. In an almost ideal QED
framework, with very favourable experimental conditions, we obtain:
  Delta alpha(-6.07GeV^2) - Delta alpha(-1.81GeV^2) = (440 pm 58 pm 43 pm 30) X
10^-5, where the first error is statistical, the second is the experimental
systematic and the third is the theoretical uncertainty. This agrees with
current evaluations of alpha(t).The null hypothesis that alpha remains constant
within the above interval of -t is excluded with a significance above 5sigma.
Similarly, our results are inconsistent at the level of 3sigma with the
hypothesis that only leptonic loops contribute to the running. This is
currently the most significant direct measurment where the running alpha(t) is
probed differentially within the measured t range.


title: Observation of h_c(^1P_1) State of Charmonium

abstract:
  The h_c(1P1) state of charmonium has been observed in the reaction \psi(2S)
-> \pi0 h_c -> (\gamma\gamma)(\gamma\eta_c) using 3.08 million \psi(2S) decays
recorded in the CLEO detector. Data have been analyzed both for the inclusive
reaction, where the decay products of the \eta_c are not identified, and for
exclusive reactions, in which \eta_c decays are reconstructed in seven hadronic
decay channels. We find M(h_c)=3524.4 +/- 0.6 +/- 0.4 MeV which corresponds to
a hyperfine splitting \Delta M_{hf}(1P) \equiv <M(3PJ)>-M(1P1)=+1.0+/-0.6+/-0.4
MeV, and B(\psi(2S)->\pi0 h_c)xB(h_c->\gamma\eta_c)=(4. +/-0.8+/-0.7)x10^{-4}.


title: KLOE results on f0(980), a0(980) scalars and eta decays

abstract:
  The KLOE experiment running at the phi-factory DAPHNE has collected ~ 450
pb^(-1) in the 2001--2002 data taking. We report preliminary results on light
meson spectroscopy based on this data sample; particles are all produced
through phi radiative decays. The nature of f0(980) and a0(980) is investigated
by studying the shape of the resulting mass spectra, which is sensitive to
their structure. A detailed study of the eta --> pi pi pi dynamics through a
Dalitz plot analysis gives the possibility to extract information on the quark
mass difference. Finally, the branching ratio for the eta --> pi0 gamma gamma
decay is compared with previous measurements and with the expectations from
Chiral Perturbation Theory.


title: B-Hadron Lifetimes and $\Delta\Gamma$ at the Tevatron

abstract:
  We present new results on the lifetimes and widths of $B$ hadrons based on
300-450 pb$^{-1}$ of data collected by CDF and D{\O}at the Fermilab Tevatron.
Lifetimes were measured in semileptonic decays as well as fully reconstructed
hadronic modes. A new measurement of the width difference between $B_s$ CP
eigenstates, $\Delta\Gamma / \bar{\Gamma} $, in $B_s$ decays to $J/\psi \phi$
is also presented.


title:
Evidence for the exclusive decay Bc+- to J/psi pi+- and measurement of
  the mass of the Bc meson

abstract:
  We report first evidence for a fully reconstructed decay mode of the
B_c^{\pm} meson in the channel B_c^{\pm} \to J/psi \pi^{\pm}, with J/psi \to
mu^+mu^-. The analysis is based on an integrated luminosity of 360 pb$^{-1} in
p\bar{p} collisions at 1.96 TeV center of mass energy collected by the Collider
Detector at Fermilab. We observe 14.6 \pm 4.6 signal events with a background
of 7.1 \pm 0.9 events, and a fit to the J/psi pi^{\pm} mass spectrum yields a
B_c^{\pm} mass of 6285.7 \pm 5.3(stat) \pm 1.2(syst) MeV/c^2. The probability
of a peak of this magnitude occurring by random fluctuation in the search
region is estimated as 0.012%.


title:
Study of Lambda/c+ Cabibbo Favored Decays Containing a Lambda Baryon in
  the Final State

abstract:
  Using data from the FOCUS experiment (FNAL-E831), we study the decay of
$\Lambda^+_c$ baryons into final states containing a $\Lambda$ hyperon. The
branching fractions of $\Lambda^+_c$ into $\Lambda \pi^+$, $\Lambda \pi^+ \pi^+
\pi^-$ and $\Lambda \bar{K} ^0 K^+$ relative to that into $pK^-\pi^+$ are
measured to be $0.217 \pm 0.013 \pm 0.020$, $0.508 \pm 0.024 \pm 0.024$ and
$0.142 \pm 0.018 \pm 0.022$, respectively. We also report new measurements of
$\frac{\Gamma(\Lambda^+_c \to \Sigma^0 \pi^+)}{\Gamma(\Lambda^+_c \to \Lambda
\pi^+)} = 1.09 \pm 0.11 \pm 0.19$, $\frac{\Gamma(\Lambda^+_c \to \Sigma^0
\pi^+\pi^+ \pi^-)}{\Gamma(\Lambda^+_c \to \Lambda \pi^+ \pi^+ \pi^-)} = 0.26
\pm 0.06 \pm 0.09$ and $\frac{\Gamma(\Lambda^+_c \to \Xi(1690)^0(\Lambda
\bar{K} ^0) K^+)}{\Gamma(\Lambda^+_c \to \Lambda \bar{K} ^0 K^+)} = 0.33 \pm
0.10 \pm 0.04$. Further, an analysis of the subresonant structure for the
$\Lambda^+_c \to \Lambda \pi^+\pi^+\pi^-$ decay mode is presented.


title: Charm Production in ep-Collisions

abstract:
  Recent results on the production of open charm in electron proton scattering
at HERA are reviewed. Results on the fragmentation of charm are presented and
compared to the measurements at e+e- colliders. Recent results on the charm
contribution to the proton structure function F2 are shown. Furthermore,
measurements of inclusive D* meson, D*+jet and D*+muon production are
presented. These results are compared with perturbative QCD calculations at
next-to-leading order as well as with Monte Carlo predictions.


title: The Flavour-Changing Neutral Currents Decay t-->Hq at ATLAS Experiment

abstract:
  The sensitivity of the ATLAS experiment to the top-quark rare decay via
flavour-changing neutral currents t --> Hq (q represents c and u quarks) has
been studied at sqrt{s} = 14 TeV in the decay mode of ttbar --> HqWb -->
WW*q,Wb -->l \nu l \nu j, l^{\pm} \nu b, (l=e, \mu).
  The Standard Model backgrounds ttbar, ttbar H, WZ and WH have been analysed.
The signal and backgrounds were generated via PYTHIA 5.7 and simulated and
analysed using ATLFAST 2.51. A branching ratio for t --> Hq -->WW*q as low as
2.0x10^{-3} for m_H=150 GeV and 2.1x10^{-3} for m_H=160 GeV could be discovered
at the 5 \sigma level with an integrated luminosity of 100 fb^{-1}.


title:
A Study of the Charge of Leading Hadrons in Gluon and Quark
  Fragmentation

abstract:
  In this study the electric charges of leading systems in quark and gluon jets
from hadronic three-jet events in $e^+e^-$-annihilation measured with the
DELPHI-experiment are examined. Leading systems are defined by a rapidity gap
between the leading system of a jet and the rest of the event. The measured
charge distributions are compared with results from Monte-Carlo simulations
which do not contain colour-octet neutralisation processes. In the data an
enhanced production of neutral leading systems compared to Monte-Carlo
predictions is found in gluon jets, which is compatible with the expectations
from colour-octet neutralisation. The quark jet sample is found in agreement
with the simulation.


title: Search for Direct CP Violation in K+-->pi+-pi+pi- Decays by NA48/2

abstract:
  First preliminary measurement of the direct CP-violating parameter Ag by the
NA48/2 experiment at CERN SPS is presented. Using more than 1.6 billions of
charged kaon decays into three charged pions, the charge asymmetry in the
K+-->pi+-pi+pi- Dalitz plot slope, Ag, has been measured to Ag = (0.5 +- 3.8) x
10^-4. This result is more than an order of magnitude more precise than results
of previous experiments.


title:
Measurement of the ttbar Production Cross Section in ppbar Collisions at
  sqrt(s)=1.96 TeV in Dilepton Final States

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 in the dilepton final states ee, emu and mumu based on
kinematical properties consistent with ttbar events. For a top quark mass of
175 GeV, we measure a top pair production cross section sigma(ttbar) = 8.6
+3.2-2.7 (stat) +/-1.1 (syst) +/-0.6 (lumi) pb, in good agreement with the
standard model prediction.


title: The X(3872) Meson and "Exotic" Spectroscopy at CDF II

abstract:
  A spate of remarkable new hadrons reported in 2003 may lead to unequivocal
proof of states beyond conventional $q\bar{q}$ and $qqq$ structure. Claimed
baryonic states Theta+, Phi, and Theta^0_c would consist of five quarks, and
new D_{sJ}-states and/or X(3872) might contain four quarks. I review efforts to
search for and study this ``new'' spectroscopy in pbarp-collisions with the CDF
II detector. Pentaquark searches are negative, and no evidence for exotic
analogs of D_{sJ}-states was found. CDF has confirmed the X(3872). My main
focus is the production and decay properties of the X(3872), and its possible
interpretations.

title:
Measurement of the branching fraction and decay rate asymmetry of B- -->
  D_{pi+pi-pi0}K-

abstract:
  We report the observation of the decay $B^- \to D_{\pi^+\pi^-\pi^0} K^-$,
where $D_{\pi^+\pi^-\pi^0}$ indicates a neutral $D$ meson detected in the final
state $\pi^+\pi^-\pi^0$, excluding $K_S \pi^0$. This doubly Cabibbo-suppressed
decay chain can be used to measure the CKM phase $\gamma$. Using about 229
million $e^+e^- \to B \bar B$ events recorded by the BaBar experiment at the
PEP-II $e^+e^-$ storage ring, we measure the branching fraction ${\cal B}(B^-
\to D_{\pi^+\pi^-\pi^0} K^-) =
  (5.5 \pm 1.0 {\rm(stat.)} \pm 0.7 {\rm(syst.)})\times 10^{-6}$ and the decay
rate asymmetry $A = 0.02 \pm 0.16 {\rm(stat.)} \pm 0.03 {\rm(syst.)}$ for the
full decay chain.


title: Top Physics Results at CDF

abstract:
  The most recent results on top quark physics at CDF are reported.
Measurements of cross-section and mass are presented, and the status of single
top quark production searches are discussed. The results obtained from probing
various top quark properties are also presented.


title: Hadron Multiplicities at HERMES

abstract:
  Hadron multiplicities of $\pim$, $\pip$, $\km$ and $\kp$ have been measured
in the deep-inelastic scattering of 27.5 GeV positrons off a hydrogen target.
The data used in this analysis have been collected during the 2000 HERA running
period. The multiplicities were obtained for 0.15$< z <$0.9 for $<Q^2>$ = 2.5
GeV$^2$.


title: Measurements of the Structure of Diffraction at HERA

abstract:
  Measurements of diffraction in electron-proton collisions are presented. All
measured processes which occur through the exchange of a virtual photon (DIS)
are consistent with a universal structure. For the diffractive photoproduction
of dijets, factorisation is broken by a global factor ~0.5 with respect to the
DIS processes.


title:
Determination of |V_ub| from Measurements of the Inclusive Charmless
  Semileptonic Partial Rates of B Mesons using Full Reconstruction Tags

abstract:
  We present a measurement of the Cabibbo-Kobayashi-Maskawa matrix element
|V_ub|, based on 253 fb^-1 of data collected by the Belle detector at the KEKB
e^+e^- asymmetric collider. Events are tagged by fully reconstructing one of
the B mesons, produced in pairs from Upsilon(4S). The signal for b->u
semileptonic decay is distinguished from the b->c background using the hadronic
mass M_X, the leptonic invariant mass squared q^2 and the variable P_+ =
E_X-|\vec{p}_X|. The results are obtained for events with the prompt-lepton
momentum, p_l^* >= 1GeV/c, in three kinematic regions (1) M_X < 1.7 Gev/c^2,
(2) M_X < 1.7 Gev/c^2 combined with q^2>8 GeV^2/c^2, and by (3) P_+ < 0.66
GeV/c, allowing for a comparison of the three methods. The matrix element
|V_ub| is found to be (4.09+-0.19+-0.20(+0.14-0.15)+-0.18), where the errors
are statistical, systematic including Monte Carlo modeling, theoretical, and
from shape function parameter determination, respectively.


title: $|V_{us}|$ and $K_S$ Decays from Kloe

abstract:
  Recent results obtained by the KLOE experiment operating at DA$\Phi$NE, the
Frascati $\phi$-factory, are presented. They mainly concern neutral kaon decays
including the $K_L$ dominant branching ratios, the $K_L$ lifetime and the
extraction of the $CKM$ parameter $V_{us}$ from the $K_L$ semileptonic decays
and lifetime. The best world upper limit on $K_S \to \pppo$ channel is also
presented


title: Polarization and asymmetries in neutral strange particle production

abstract:
  Inclusive Lambda, Antilambda and K0s production in deep inelastic ep
scattering has been studied with the ZEUS detector at HERA using an integrated
luminosity of 120 pb^-1. Differential cross sections, baryon to antibaryon
asymmetry and baryon to meson production have been measured in the laboratory
system for Q2 > 25 GeV^2.


title: Measurement of B(t->Wb)/B(t->Wq) at the Collider Detector at Fermilab

abstract:
  We present a measurement of the ratio of top-quark branching fractions R= B(t
-> Wb)/B(t -> Wq), where q can be a b, s or a d quark, using lepton-plus-jets
and dilepton data sets with integrated luminosity of ~162 pb^{-1} collected
with the Collider Detector at Fermilab during Run II of the Tevatron. The
measurement is derived from the relative numbers of t-tbar events with
different multiplicity of identified secondary vertices. We set a lower limit
of R > 0.61 at 95% confidence level.


title: Measurement of Time-Dependent CP Asymmetries in B0 -> D(*)D Decays

abstract:
  We present a first measurement of CP asymmetries in neutral B decays to D+D-,
and updated CP asymmetry measurements in decays to D*+D- and D*-D+. We use
fully-reconstructed decays collected in a data sample of (232 +- 3) x 10^6
Y(4S) -> BBbar events in the BABAR detector at the PEP-II asymmetric-energy B
Factory at SLAC. We determine the time-dependent asymmetry parameters to be
S_{D*+D-} = -0.54 +- 0.35 +- 0.07, C_{D*+D-} = 0.09 +- 0.25 +- 0.06, S_{D*-D+}
= -0.29 +- 0.33 +- 0.07, C_{D*-D+} = 0.17 +- 0.24 +- 0.04, S_{D+D-} = -0.29 +-
0.63 +- 0.06, and C_{D+D-} = 0.11 +- 0.35 +- 0.06, where in each case the first
error is statistical and the second error is systematic.


title:
First Measurements of eta_c Decaying into K^+K^-2(pi^+pi^-) and
  3(pi^+pi^-)

abstract:
  The decays of eta_c to K^+K^-2(pi^+pi^-) and 3(pi^+pi^-) are observed for the
first time using a sample of 5.8X10^7 J/\psi events collected by the BESII
detector. The product branching fractions are determined to be B(J/\psi-->gamma
eta_c)*B(eta_c-->K^+K^-pi^+pi^-pi^+pi^-)=(1.21+-0.32+-
0.23)X10^{-4}$,B(J/\psi-->gamma eta_c)*B(eta_c-->K^{*0}\bar{K}^{*0}pi^+pi^-)=
(1.29+-0.43+-0.32)X10^{-4}$, and (J/\psi-->gamma eta_c)*
B(eta_c-->pi^+pi^-pi^+pi^-pi^+pi^-)= (2.59+-0.32+-0.48)X10^{-4}. The upper
limit for eta_c-->phi pi^+pi^-pi^+pi^- is also obtained as B(J/\psi-->gamma
eta_c)*B(eta_c--> phi pi^+pi^-pi^+pi^-)< 6.03 X10^{-5} at the 90% confidence
level.


title: Searches for New Physics in ep Collisions at HERA

abstract:
  Recent results from searches for physics beyond the Standard Model (SM) in
electron/positron-proton collisions at HERA at center-of-mass energies of 300
and 320 GeV are presented. They were performed on a data sample collected in
the period 1994-2004 by the H1 and ZEUS collaborations. The data have been
analysed searching for leptoquarks, light gravitinos in R-parity violating
supersymmetric models and magnetic monopoles. Results of a general search for
new phenomena at high transverse momentum and of a dedicated search for events
with isolated leptons and missing transverse momentum are also reported.


title: Top Physics Results from CDF

abstract:
  The top quark is by far the most massive fundamental particle observed so
far, and the study of its properties is interesting for several reasons ranging
from its possible special role in electroweak symmetry breaking to its
sensitivity to physics beyond the Standard Model. We present recent top physics
results from CDF based on 160-320 inverse pb of ppbar collision data at a
center-of-mass energy of 1.96 TeV. The ttbar cross section and the top mass
have been measured in different decay channels and using different methods. We
have searched for evidence of single top production, setting upper limits on
its production rate. Other results shown in this conference include studies of
the polarization of W bosons from top decays, a search for charged Higgs
decaying from top, and a search for additional heavy t' quarks.


title: Measurement of the Higgs Boson Mass with a Linear e+e- Collider

abstract:
  The potential of a linear e+e- collider operated at a centre-of-mass energy
of 350 GeV is studied for the measurement of the Higgs boson mass. An
integrated luminosity of 500 fb-1 is assumed. For Higgs boson masses of 120,
150 and 180 GeV the uncertainty on the Higgs boson mass measurement is
estimated to be 40, 65 and 70 MeV, respectively. The effects of beam related
systematics, namely a bias in the beam energy measurement, the beam energy
spread and the luminosity spectrum due to beamstrahlung, on the precision of
the Higgs boson mass measurement are investigated. In order to keep the
systematic uncertainty on the Higgs boson mass well below the level of the
statistical error, the beam energy measurement must be controlled with a
relative precision better than 10-4.


title: Search for the b --> d gamma process

abstract:
  We report the results of a search for the flavor-changing neutral current
process b --> d gamma using a sample of 275 million B meson pairs accumulated
by the Belle detector at KEKB. We find no significant signal for the exclusive
decays B- --> rho- gamma, B0B --> rho0 gamma, or B0B --> omega gamma. Assuming
an isospin relation between the three modes, we set an upper limit for the
combined branching fraction Br(B --> (rho,omega) gamma) < 1.4 x 10-6 at the 90%
confidence level. This limit can be used to constrain the ratio of CKM matrix
elements |Vtd/Vts|.


title: Baryonic B decays

abstract:
  We summarize recent results of baryonic B decays from Belle and BaBar. The
results from Belle are based on 140 /fb and results from BaBar are based on 81
/fb of data collected at the Upsilon(4S) resonance at KEKB or PEPII
respectively. We report the results of two- and three-body baryonic B decays as
well as searches for pentaquarks. The three-body baryonic B decays display an
enhancement in the low mass region, which is not in agreement with general
phase space expectations.


title: Search for the Rare Decays B+ --> D(*)+K0s

abstract:
  We report on the search for the rare decays $B^+ \to D^{(*)+} K^0_{s}$ in
approximately 226 million $Y(\rm 4S)\to b\bar{B}$ decays collected with the
BaBar detector at the PEP-II asymmetric-energy $B$ factory at SLAC. We do not
observe any significant signal and we set 90% confidence level upper limits on
the branching fractions, ${\ensuremath {{\cal B}(\Bp{\to}D^{+}K^0})}$ $<0.5
\times 10^{-5}$ and ${\ensuremath {{\cal B}(\Bp{\to}D^{*+}K^0})}$ $<0.9 \times
10^{-5}$.


title: Averages of b-hadron Properties as of Winter 2005

abstract:
  This article reports world averages for measurements on b-hadron properties
obtained by the Heavy Flavor Averaging Group (HFAG) using the available results
as of winter 2005 conferences. In the averaging, the input parameters used in
the various analyses are adjusted (rescaled) to common values, and all known
correlations are taken into account. The averages include lifetimes, neutral
meson mixing parameters, semileptonic decay parameters, rare decay branching
fractions, and CP violation measurements.


title:
Observation of Thirteen New Exclusive Multi-Body Hadronic Decays of the
  $\psi(2S)$

abstract:
  Using data accumulated with the CLEO detector corresponding to an integrated
luminosity of 5.63 pb^-1 on the peak of the psi(2S) and 20.70 pb^-1 continuum
at 3.67 GeV, we report first measurements of the branching fractions for the
following 13 decay modes of the psi(2S): eta 3pi, eta^\prime 3pi, rho K^+K^-,
K^+K^-pi^+pi^-pi^0, 2(K^+K^-), 2(K^+K^-)pi^0, rho p \bar p, p \bar p
pi^+pi^-pi^0, eta p \bar p, p \bar p K^+K^-, Lambda \bar Lambda pi^+pi^-,
Lambda \bar p K^+, Lambda \bar p K^+pi^+pi^-, and more precise measurements of
8 previously measured modes: 2(pi^+pi^-), rho pi^+pi^-, 2(pi^+pi^-)pi^0, omega
pi^+pi^-, K^+K^-pi^+pi^-, omega K^+K^-, phi K^+K^-, p \bar p pi^+pi^-. We also
report new branching fraction measurements of phi pi^+pi^- and omega p \bar p
and upper limits for eta pi^+pi^-, eta K^+K^- and phi p \bar p. Results are
compared, where possible, with the corresponding J/psi branching ratios to
provide new tests of the 12% rule.


title:
Measurement of the $\ttbar$ Production Cross Section in $\ppbar$
  Collisions at $\sqrt{s}=1.96 TeV Using Lepton Plus Jets Events with
  Semileptonic B Decays to Muons

abstract:
  We present a measurement of the $\ttbar$ production cross section using $194
\mathrm{pb^{-1}}$ of CDF II data using events with a high transverse momentum
electron or muon, three or more jets, and missing transverse energy. The
measurement assumes 100% $t\to Wb$ branching fraction. Events consistent with
$\ttbar$ decay are found by identifying jets containing heavy flavor
semileptonic decays to muons. The dominant backgrounds are evaluated directly
from the data. Based on 20 candidate events and an expected background of
9.5$\pm$1.1 events, we measure a production cross section of
$5.3\pm3.3^{+1.3}_{-1.0} \mathrm{pb}$, in agreement with the standard model.


title:
Nuclear-atomic state degeneracy in neutrinoless double-electron capture:
  A unique test for a Majorana-neutrino

abstract:
  There is a general consensus that detection of a double-beta decay without
any neutrino involved would mark physics beyond the Standard Model. This is
because in such decay modes lepton number conservation would be violated and
the neutrino would reveal itself as being its own antiparticle, thereby of
Majorana type. So far, the experimental focus has mostly been on the double
beta minus decay variant, where one attempts to measure the spectrum of the two
emitted electrons. A discrete line at the endpoint energy marks the unique
signature for a Majorana neutrino. Little attention has been given to
alternative decay modes in double-beta decay. In this note we show that there
is at least one case in the periodic table, where the parent in the
neutrinoless double-electron capture process is nearly degenerate with an
excited state in the daughter, leading to a possible enhancement of the decay
rate by several orders of magnitude. It is the nucleus 74-Se, which has this
unique property. Furthermore, there is an easy to detect 2 gamma-ray decay
cascade in 74-Ge, which follows the zero-neutrino double electron capture, and
which by its mere detection provides unique signature of the Majorana neutrino.

Nuclear effects in high-p_T production of direct photons and neutral
  mesons

abstract:
  We present results on the production of direct photons, pizero, and eta
mesons on nuclear targets at large transverse momenta (p_T). The data are from
530 and 800 GeV/c proton beams and 515 GeV/c piminus beams incident upon copper
and beryllium targets that span the kinematic range of 1.0 < p_T < 10 GeV/c at
central rapidities.


title:
Measurement of the Deuteron Structure Function F2 in the Resonance
  Region and Evaluation of Its Moments

abstract:
  Inclusive electron scattering off the deuteron has been measured to extract
the deuteron structure function F2 with the CEBAF Large Acceptance Spectrometer
(CLAS) at the Thomas Jefferson National Accelerator Facility. The measurement
covers the entire resonance region from the quasi-elastic peak up to the
invariant mass of the final-state hadronic system W~2.7 GeV with four-momentum
transfers Q2 from 0.4 to 6 (GeV/c)^2. These data are complementary to previous
measurements of the proton structure function F2 and cover a similar
two-dimensional region of Q2 and Bjorken variable x. Determination of the
deuteron F2 over a large x interval including the quasi-elastic peak as a
function of Q2, together with the other world data, permit a direct evaluation
of the structure function moments for the first time. By fitting the Q2
evolution of these moments with an OPE-based twist expansion we have obtained a
separation of the leading twist and higher twist terms. The observed Q2
behaviour of the higher twist contribution suggests a partial cancellation of
different higher twists entering into the expansion with opposite signs. This
cancellation, found also in the proton moments, is a manifestation of the
"duality" phenomenon in the F2 structure function.


title: Top Quark Production and Properties at the Tevatron

abstract:
  The precise measurement of top quark production and properties is one of the
primary goals of the Tevatron during Run II. The total top-antitop production
cross-section has been measured in a large variety of decay channels and using
different selection criteria. Results from differential cross-section
measurements and searches for new physics in top-antitop production and top
quark decays are available. Electroweak production of single top quarks has
been searched for. The results from all these analyses, using typically 200/pb
of data, are presented.


title: Studies of Beauty at H1 and ZEUS

abstract:
  Recent measurements of beauty production in ep collisions at HERA are
presented. The results were obtained using data from the experiments H1 and
ZEUS from the years 1996 to 2000 (HERA I). An outlook is given for analysis on
data from HERA II. Differential measurements using muons and jets in deep
inelastic scattering and photoproduction are compared to NLO QCD predictions.
The beauty contribution to the proton structure function F_2 was determined at
large Q^2 (Q^2 > 150 GeV^2) and is compared with predictions.


title: Search for the Decay tau to seven pion (pizero)

abstract:
  A search for the decay of the tau lepton to seven charged pions and one or
zero pizero mesons was performed using the BaBar detector at the PEP-II
asymmetric-energy e+e- collider.
  The analysis uses 232.2 fb-1 of data at center-of-mass energies on or near
the Y(4S) resonance. We observe 24 events with an expected background of
21.6+-1.3 events. Without evidence for a signal, we calculate an upper limit of
BR(tau- --> 4pi- 3pi+ (pizero) nu_tau) < 3.0*10^-7 at 90 % confidence level.
  This is an improvement by nearly an order of magnitude over the previously
established limit. In addition, we set upper limits for the exclusive decays
tau- --> 4pi- 3pi+ nu_tau and tau- --> 4pi- 3pi+ pizero nu_tau.


title:
Search for coherent charged pion production in neutrino-carbon
  interactions

abstract:
  We report the result from a search for charged-current coherent pion
production induced by muon neutrinos with a mean energy of 1.3 GeV. The data
are collected with a fully active scintillator detector in the K2K
long-baseline neutrino oscillation experiment. No evidence for coherent pion
production is observed and an upper limit of $0.60 \times 10^{-2}$ is set on
the cross section ratio of coherent pion production to the total
charged-current interaction at 90% confidence level. This is the first
experimental limit for coherent charged pion production in the energy region of
a few GeV.


title: Interactions of R-hadrons in ATLAS

abstract:
  In this talk the detection possibilities of R-hadrons in the ATLAS detector
are studied. R-hadrons are stable hadronized gluinos, predicted by certain
supersymmetric models. Making use of fully simulated R-hadrons, signatures of
single R-hadrons in the ATLAS subdetector are studied, and triggering issues
are addressed. Fast simulation is used to study the discovery potential. The
abundant production of R-hadrons at the LHC, will allow a quick discovery for a
broad range of masses.


title: Photoproduction of Baryons Decaying into N pi and N eta

abstract:
  A combined analysis of photoproduction data on \gamma p to \pi N, eta N was
performed including the data on K Lambda and K Sigma. The data are interpreted
in an isobar model with s--channel baryon resonances and pi, rho,(omega), K,
and K^* exchange in the t--channel. Three baryon resonances have a substantial
coupling to eta N, the well known N(1535)S_{11}, N(1720)P_{13}, and
N(2070)D_{15}. The inclusion of data with open strangeness reveals the presence
of further new resonances, N(1840)P_{11}, N(1875)D_{13} and N(2170)D_{13}.


title: Decays of Baryon Resonances into K Lambda, K^+ Sigma^0 and K^0 Sigma^+

abstract:
  Cross sections, beam asymmetries, and recoil polarisations for the reactions
gamma p to K^+ Lambda ; gamma to K^+ Sigma^0, and gamma p to K^0 Sigma^+ have
been measured by the SAPHIR, CLAS, and LEPS collaborations with high statistics
and good angular coverage for centre-of-mass energies between 1.6 and 2.3 GeV.
The combined analysis of these data with data from pi and eta photoproduction
reveals evidence for new baryon resonances in this energy region. A new P_{11}
state with mass 1840 MeV and width 140 MeV was observed contributing to most of
the fitted reactions. The data demand the presence of two D_{13} states at 1870
and 2170 MeV.


title: Search for T Violation in Charm Meson Decays

abstract:
  Using data from the FOCUS (E831) experiment, we have searched for T violation
in charm meson decays using the four-body decay channels $D^0 \to
K^-K^+\pi^-\pi^+$, $D^+ \to K^0_SK^+\pi^-\pi^+$, and $D^+_s \to
K^0_SK^+\pi^-\pi^+$. The T violation asymmetry is obtained using triple-product
correlations and assuming the validity of the CPT theorem. We find the
asymmetry values to be
  $A_Tviol (D^0) = 0.010 \pm 0.057(stat.) \pm 0.037(syst.)$,
  $A_Tviol (D^+) = 0.023 \pm 0.062(stat.) \pm 0.022(syst.)$, and
  $A_Tviol (D^+_s) = -0.036 \pm 0.067(stat.) \pm 0.023(syst.)$.
  Each measurement is consistent with no T violation. New measurements of the
CP asymmetries for some of these decay modes are also presented.


title: Search for a strongly decaying neutral charmed pentaquark

abstract:
  We present a search for a charmed pentaquark decaying strongly to
$D^{(*)-}p$. Finding no evidence for such a state, we set limits on the cross
section times branching ratio relative to $D^{*-}$ and $D^-$ under particular
assumptions about the production mechanism.


title: Magnetic Monopole Searches

abstract:
  In these lecture notes we discuss the status of the searches for classical
Dirac Magnetic Monopoles (MMs) at accelerators, for GUT superheavy MMs in the
penetrating cosmic radiation and for Intermediate Mass MMs. Also the searches
for nuclearites and Q-balls are considered.


title: Improved description of Bose-Einstein Correlation function

abstract:
  The L3 data on Bose-Einstein correlations of equally charged pion pairs
produced in hadronic Z decays are analyzed in terms of various
parametrizations. Preliminary results are presented here.


title: W Boson Production and Mass at the Tevatron

abstract:
  The CDF and D0 collaborations have analyzed up to ~200/pb of Run 2 physics
data to measure W production properties such as the W cross section, the W
width, lepton universality and the W charge asymmetry. From the cross section
measurements, CDF obtains a lepton universality of g_mu/g_e = 0.998+-0.012 and
g_tau/g_e = 0.99+-0.04 and an indirect W width of Gamma_W = 2079+-41 MeV. D0
measured the W width directly and finds Gamma_W = 2011+-142 MeV. CDF has
estimated the uncertainties on the W boson mass measurements in the electron
and muon decay channels and obtains an overall uncertainty of 76 MeV.


title: Recent Results from KTeV

abstract:
  The implications of the published KTeV $K^0_L \to \pi^0\mu^+\mu^-$ result for
interpreting recent $\Sigma^+ \to p\mu^+\mu^-$ results are discussed. The
status of the KTeV $\Xi^0 \to \Sigma^+\mu^-\nu$ analysis is given. The KTeV
$|V_{us}|$ result is also given.


title: First Measurement of the Tensor Structure Function $b_1$ of the Deuteron

abstract:
  The \Hermes experiment has investigated the tensor spin structure of the
deuteron using the 27.6 GeV/c positron beam of \Hera. The use of a tensor
polarized deuteron gas target with only a negligible residual vector
polarization enabled the first measurement of the tensor asymmetry $\At$ and
the tensor structure function $\bd$ for average values of the Bj{\o}rken
variable $0.01<< x><0.45$ and of the squared four-momentum transfer $0.5 {\rm
GeV^2}<< Q^2 > <5 {\rm GeV^2}$. The quantities $\At$ and $\bd$ are found to be
non-zero. The rise of $\bd$ for decreasing values of $x$ can be interpreted to
originate from the same mechanism that leads to nuclear shadowing in
unpolarized scattering.


title: Beauty production with the ALICE detector

abstract:
  Heavy flavour pairs produced in hadronic reactions provide a valuable
laboratory for the study of strong interactions. Due to their relatively large
mass, the production of heavy quarks should be reliably calculable in the
perturbative approach. Charm and beauty quarks once produced in a heavy ion
collision have to propagate through the surrounding quark-gluon matter. Heavy
quark states are then a sensitive probe of the properties of the dense medium.
ALICE is a general-purpose experiment equipped to reconstruct, among other
signals, leptons from open charm and beauty via their leptonic decays in p-p,
p-A and A-A collisions. In these proceedings, we present feasibility studies
for ALICE measurements of beauty production in central Pb-Pb collisions at
s_{NN}^1/2=5.5TeV using semileptonic decays.


title: Study of J/psi decays to Lambda Lambdabar and Sigma0 Sigma0bar

abstract:
  The branching ratios and Angular distributions for J/psi decays to Lambda
Lambdabar and Sigma0 Sigma0bar are measured using BESII 58 million J/psi.


title: Spectroscopic Measurements Using the H1 and ZEUS Detectors

abstract:
  Results on spectroscopy from the H1 and ZEUS collaborations are presented.
The main focus is to search for baryon states which could be interpreted as
pentaquarks. This includes states decaying to K^0_sp and K^0_s\bar{p}, \Xi\pi
and D*p. In addition an analysis of K^0_sK^0_s resonances is covered.


title: Comments to D0note 4760-CONF

abstract:
  A brainstorming on recent D0 data on a search for the Higgs boson in H ->
WW(*)-> l(+)nu l'(-)nu (l, l' = e, mu) decays is performed. As a result, it is
possible that the data favors m(H) = 160 GeV if there are four SM families.


title: Observation of the radiative kaon decay K- --> mu-pi0gammanu

abstract:
  Using data collected with the ISTRA+ spectrometer during the 2001 run of the
U-70 proton synchrotron in Protvino, we report the first observation of the
radiative kaon decay K- -->mu-pi0gammanu. We find Br(Kmu3g)/Br(Kmu3) for two
regions 5<Eg<30 and 30<Eg<60 MeV consistent with theoretical predictions. The
measured angular distribution asymmetry for the first region,
  0.093+/-0.141, is two standard deviations away from the theoretical
prediction of 0.354. The measured asymmetry in the T-odd variable is
-0.03+/-0.13.


title: Top Physics at the LHC

abstract:
  Top quark physics will be a prominent topic in Standard Model physics at the
LHC. The enormous amount of top quarks expected to be produced will allow to
perform a wide range of precision measurements. An overview of the planned top
physics programme of the ATLAS and CMS experiments at the LHC is given.


title: W/Z Production Cross Sections and Asymmetries at E_CM = 2 TeV

abstract:
  The most recent results for W and Z boson production cross sections and
asymmetries are presented from the CDF and D0 collaborations using Run II data
taken at the Fermi National Accelerator Laboritory (FNAL) Tevatron. Data set
sizes range from 72pb^(-1) to 226pb^(-1), and results range from published to
preliminary. Results presented agree with the Standard Model and world averages
within errors.


title: Top Quark Results from D0

abstract:
  In this talk I will present recent preliminary results from the D0 experiment
from Tevatron Run II ($p\bar p$ collisions at $\sqrt{s} = 1.96$ TeV). The
results presented in this talk include top quark pair production cross section,
top quark mass, and upper limits on single top quark production.


title:
Boost Invariance and Multiplicity Dependence of the Charge Balance
  Functionin $\pi^{+}p$ and $K^{+}p$ Collisions at $\sqrt s= 22$ GeV/c

abstract:
  Boost invariance and multiplicity dependence of the charge balance function
are studied in $\pi^{+}\rp$ and $\rK^{+}\rp$ collisions at 250 GeV/$c$ incident
beam momentum. Charge balance, as well as charge fluctuations, are found to be
boost invariant over the whole rapidity region, but both depend on the size of
the rapidity window. It is also found that the balance function becomes
narrower with increasing multiplicity, consistent with the narrowing of the
balance function when centrality and/or system size increase, as observed in
current relativistic heavy ion experiments.


title: Upper Limit on the Branching Ratio for the Decay $\pi^0 \to \nu \bar\nu$

abstract:
  A sample of kinematically identified $K^+ \to \pi^+ \pi^0$ decays obtained
with the E949 detector was used to search for the helicity-suppressed decay
$\pi^0 \to \nu \bar{\nu}$ resulting in an upper limit of $2.7\times10^{-7}$ at
90% confidence level.The upper limit is also applicable to $\pi^0$ decays into
unknown weakly interacting particles.


title:
Entropy Analysis in $\pi^{+}\rp$ and $\rK^{+}\rp$ Collisions at
  $\sqrt{s}=22$ GeV

abstract:
  The entropy properties are analyzed by Ma's coincidence method in
$\pi^{+}\rp$ and $\rK^{+}\rp$ collisions of the NA22 experiment at 250 GeV/$c$
incident momentum. By using the R\'{e}nyi entropies, we test the scaling law
and additivity properties in rapidity space. The behavior of the R\'{e}nyi
entropies as a function of the average number of particles is investigated. The
results are compared with those from the {\sc Pythia} Monte Carlo event
generator.


title: Top Quark Mass Measurements at the Tevatron

abstract:
  In the year 2004 several milestones in the measurement of the top quark mass
were reached. The DO collaboration published a significant improvement of their
Run I measurement of the top quark mass, and both Tevatron experiments released
preliminary measurements based on Run II data sets collected in the period
2002-2004. The preliminary Run II results presented here do not yet surpass the
current world average in precision, but this is expected to change soon. With
larger data sets ready to be analyzed, a better understanding of the Run II
detectors and improved analysis methods, 2005 promises to be a remarkable year
for Top physics.


title: Hadronic B and D studies at BABAR

abstract:
  We present new results on hadronic B and D decays from the BABAR experiment.
The first part of this document presents searches for new channels which may be
used for CP measurements. The second part is dedicated to hadronic decays with
tests of QCD factorization predictions and other models for B structure and
decay mechanisms. A new result on the reference branching ratio Ds+ -->phi pi+
is also reported.


title: Measurements of muon flux in the Pyh\"asalmi underground laboratory

abstract:
  The cosmic-ray induced muon flux was measured at several depths in the
Pyh\"asalmi mine (Finland) using a plastic scintillator telescope mounted on a
trailer. The flux was determined at four different depths underground at 400 m
(980 m.w.e), at 660 m (1900 m.w.e), at 990 m (2810 m.w.e) and at 1390 m (3960
m.w.e) with the trailer, and also at the ground surface. In addition,
previously measured fluxes from depths of 90 m (210 m.w.e) and 210 m (420
m.w.e) are shown. A relation was obtained for the underground muon flux as a
function of the depth. The measured flux follows well the general behaviour and
is consistent with results determined in other underground laboratories.


title: Measurement of phi_3

abstract:
  We present results related to determination of the Unitarity Triangle angle
phi_3.


title:
Search for New Physics Using High Mass Tau Pairs from 1.96-TeV
  Proton-Antiproton Collisions

abstract:
  We present the results of a search for anomalous resonant production of tau
lepton pairs with large invariant mass, the first such search using the CDF II
Detector in Run II of the Tevatron $p\bar{p}$ collider. Such anomalous
production could arise from various new physics processes. In a data sample
corresponding to 195 pb$^{-1}$ of integrated luminosity we predict 2.8$\pm$0.5
events from Standard Model background processes and observe 4. We use this
result to set limits on the production of heavy scalar and vector particles
decaying to tau lepton pairs.


title: Precision Measurements of alphas at HERA

abstract:
  The precision measurements of the strong coupling constant, alphas, and its
energy-scale dependence carried out at HERA by the H1 and ZEUS Collaborations
are reviewed. An average value of alphas(Mz) = 0.1186 +- 0.0011 (exp.) +-
0.0050 (th.) is obtained from these measurements. The combined HERA
determinations of the energy-scale dependence of alphas clearly show the
running of alphas from jet data alone and are in agreement with the running of
the coupling as predicted by QCD.


title:
Determination of |Vub| from Measurements of the Electron and Neutrino
  Momenta in Inclusive Semileptonic B Decays

abstract:
  We present a determination of the CKM matrix element |Vub| based on the
analysis of semileptonic B decays from a sample of 88 million Upsilon(4S)
decays collected with the BABAR detector at the PEP-II e+e- storage ring.
Charmless semileptonic B decays are selected using measurements of the electron
energy and the invariant mass squared of the electron-neutrino pair. We obtain
|Vub| = (3.95 +/- 0.26 ^{+0.58}_{-0.42} +/- 0.25) x 10^{-3}, where the errors
represent experimental uncertainties, heavy quark parameter uncertainties, and
theoretical uncertainties, respectively.


title:
Measurement of high-Q2 deep inelastic scattering cross sections with
  longitudinally polarised positron beams at HERA

abstract:
  The first measurements of the cross sections for neutral and charged current
deep inelastic scattering in e+p collisions with longitudinally polarised
positron beams are presented. The total cross section for e+p charged current
deep inelastic scattering is presented at positive and negative values of
positron beam longitudinal polarisation for an integrated luminosity of 37.0
pb^-1 H1 data and 30.5 pb^-1 ZEUS data collected in 2003 and 2004 at a
centre-of-mass energy of 319 GeV. In addition, the ZEUS collaboration measured
the single differential cross sections for charged and neutral current deep
inelastic scattering in the kinematic region Q^2>200 GeV^2. The measured cross
sections are compared with the predictions of the Standard Model. The H1
collaboration extrapolate the cross section to a fully left handed positron
beam and find it to be consistent with the Standard Model expectation.


title: Latest Jets Results from the Tevatron at $\sqrt{s}=1.96 \mathrm{TeV}$

abstract:
  Latest jet results from the Tevatron are presented in this conference note.
These are namely: new results on central inclusive jet production using both
cone and $k_T$ algorithms, measurement of decorrelation in azimuthal angle
between the two jets with the highest transverse momenta, and study of jet
shapes. Results are based on data collected in $\mathrm{p}\bar{\mathrm{p}}$
collisions at $\sqrt{s}=1.96 \mathrm{TeV}$ in the years 2001-2004. Depending on
the analysis, integrated luminosity of the sample was up to $378
\mathrm{pb}^{-1}$.


title: New resonances in B-meson decays

abstract:
  The X(3872) and Y(3940) properties and decay modes from Belle are reviewed
and the results on a search for the decay $B^+\ra h_c K^+$, $h_c\ra \eta_c
\gamma$ at Belle are presented.


title:
S-wave $K^-\pi+$ System in $D^+\to K^-\pi^+\pi^+$ Decays from Fermilab
  E791

abstract:
  A new approach to the analysis of three body decays is presented.
Model-independent results are obtained for the \swave $K\pi$ amplitude as a
function of $K\pi$ invariant mass. These are compared with results from
$\Km\pip$ elastic scattering, and the prediction of the Watson theorem, that
the phase behavour be the same below $K\eta^{\prime}$ threshold, is tested.
Contributions from $I=\half$ and $I={3\over 2}$ are not resolved in this study.
If $I=\half$ dominates, however, the Watson theorem does not describe these
data well.}


title: Latest Results from PHOBOS at RHIC

abstract:
  A study of charged hadron production in d+Au and Au+Au collisions is
presented at various collision energies (sqrt(s)=19.6 to 200 GeV per nucleon).
Scaling and factorization features of transverse momentum and pseudorapidity
distributions and elliptic flow are discussed as a function of collision energy
and centrality.


title:
A Search for Supersymmetric Higgs Bosons in the Di-Tau Decay Mode in
  Proton Anti-Proton Collisions at sqrt(s)=1.8 TeV

abstract:
  A search for direct production of Higgs bosons in the di-tau decay mode is
performed with 86.3 +/- 3.5 pb^-1 of data collected with the Collider Detector
at Fermilab during the 1994-1995 data taking period of the Tevatron. We search
for events where one tau decays to an electron plus neutrinos and the other tau
decays hadronically. We perform a counting experiment and set limits on the
cross section for supersymmetric Higgs boson production where tan(beta) is
large and m_A is small. For a benchmark parameter space point where m_A=100
GeV/c^2 and tan(beta)=50, we limit the production cross section multiplied by
the branching ratio to be less than 77.9 pb at the 95% confidence level
compared to the theoretically predicted value of 11.0 pb. This is the first
search for Higgs bosons decaying to tau pairs at a hadron collider.


title: Semileptonic and Electroweak Penguin Results from BABAR

abstract:
  We report recent results from the BABAR experiment on semileptonic charmless
B-meson decays and electroweak penguin processes. Semileptonic charmless decays
are used to determine |Vub| and the exclusive modes considered here also begin
to constrain QCD-lattice form factor calculations. Radiative penguin decays are
both sensitive to physics beyond the Standard Model and can be used to extract
Heavy Quark parameters related to the b-quark mass and its motion inside the
hadron.


title: Search for Leptoquark Bosons in ep Collisions at HERA

abstract:
  A search for scalar and vector leptoquarks coupling to first generation
fermions is performed using the e^+p and e^-p scattering data collected by the
H1 experiment between 1994 and 2000. The data correspond to a total integrated
luminosity of 117 pb^{-1}. No evidence for the direct or indirect production of
such particles is found in data samples with a large transverse momentum final
state electron or with large missing transverse momentum. Constraints on
leptoquark models are established. For leptoquark couplings of electromagnetic
strength, leptoquarks with masses up to 275-325 GeV are ruled out. These limits
improve and supercede earlier H1 limits based on subsamples of the data used
here.


title: Obervation of \chi_{cJ}--> omega omega decays

abstract:
  Decays of $\chi_{c0,2}\ar\ww$ are observed for the first time using a sample
of $14.0\times 10^6$ $\psi(2S)$ events collected with the BESII detector. The
branching ratios are determined to be ${\cal B}(\chi_{c0}\ar \ww)=(2.29\pm
0.58\pm 0.41)\times 10^{-3}$ and ${\cal B}(\chi_{c2}\ar\ww)=(1.77\pm 0.47\pm
0.36)\times 10^{-3}$, where the first errors are statistical and the second
systematic. The significances of the two signals are $4.4\sigma$ and
$4.7\sigma$, respectively.


title: B Physics Prospects at LHC

abstract:
  Future Experiments at LHC will have the opportunity to pursue an extensive
program on B Physics and CP violation. The expected performance are presented
here.


title: Overview of LHCb

abstract:
  An overview of LHCb experiment is given, focusing on detector, trigger and
expected physics performances. LHCb is a second generation b physics experiment
design to do precise measurements of CP violation in B meson system and to
study b hadron rare decays.


title: Boson Gauge Couplings at LEP

abstract:
  The review of the measurements of the gauge couplings in the boson sector at
LEP is presented. The measurements of the charged triple gauge couplings (cTGC)
parameters from the four LEP experiments are combined and the results are in
good agreement with the Standard Model predictions, proving the non-abelian
structure of the SU(2)_L x U(1)_Y gauge simmetry. Different measurements of
these parameters are reviewed and all possible fit methods discussed. The
current limits on the anomalous neutral triple gauge couplings (nTGC) and the
quartic gauge coplings (QGC) are also presented.


title: b-Physics measurements at the Tevatron: m and Delta m

abstract:
  We present experimental results on b-hadron mass measurements and b-meson
oscillations based on integrated luminosity of 250 to 450 pb-1 of
proton-antiproton collisions at c.m. energy = 1.98 TeV by the CDF and D0
collaborations at the Tevatron. The masses of b-hadrons have been measured
precisely by the CDF collaboration in decays containing a J/psi . A blind
search of the decay mode Bc to J/psi pi resulted in a peak of 18.9 +/- 5.4
candidates at a mass value of 6287.0 +/- 4.5 +/- 1.1 MeV/c2. A new limit has
been set to the decay B_d,s to mu+ mu-. Both the CDF and D0 collaborations are
in the position to put a limit on the frequency of the Bs oscillations. D0
reports Delta m_s > 5.0 ps-1.


title:
Results on the Coherent Interaction of High Energy Electrons and Photons
  in Oriented Single Crystals

abstract:
  The CERN-NA-59 experiment examined a wide range of electromagnetic processes
for multi-GeV electrons and photons interacting with oriented single crystals.
The various types of crystals and their orientations were used for producing
photon beams and for converting and measuring their polarisation.
  The radiation emitted by 178 GeV unpolarised electrons incident on a 1.5 cm
thick Si crystal oriented in the Coherent Bremsstrahlung (CB) and the
String-of-Strings (SOS) modes was used to obtain multi-GeV linearly polarised
photon beams.
  A new crystal polarimetry technique was established for measuring the linear
polarisation of the photon beam. The polarimeter is based on the dependence of
the Coherent Pair Production (CPP) cross section in oriented single crystals on
the direction of the photon polarisation with respect to the crystal plane.
Both a 1 mm thick single crystal of Germanium and a 4 mm thick multi-tile set
of synthetic Diamond crystals were used as analyzers of the linear
polarisation.
  A birefringence phenomenon, the conversion of the linear polarisation of the
photon beam into circular polarisation, was observed. This was achieved by
letting the linearly polarised photon beam pass through a 10 cm thick Silicon
single crystal that acted as a "quarter wave plate" (QWP) as suggested by N.

title:
Determination of the branching fractions for $\psi(3770) \to D^0 \bar
  D^0, D^+D^-,D\bar D$ and $\psi(3770) \to {\rm non-}D\bar D$

abstract:
  The branching fractions for $\psi(3770) \to D^0 \bar D^0, D^+D^-,D\bar D$ and
$\psi(3770) \to {\rm non-}D\bar D$ are determined based on the cross sections
for $\psi(3770)$ and $D \bar D$ production measured by BES Collaboration. From
its recent publications we determine the branching fractions for $\psi(3770)
\to D^0 \bar D^0, D^+D^-$ and $\psi(3770) \to D\bar D$ to be $(52.2\pm 4.8\pm
5.5)%$, $(37.0 \pm 5.0 \pm 4.3)%$ and $(89.1 \pm 6.9 \pm 9.2)%$, respectively.
The latter one implies the branching fraction for $\psi(3770) \to {\rm
non-}D\bar D$ to be $(10.9 \pm 6.9 \pm 9.2)%$, corresponding the inclusive
${\rm non-}D \bar D$ partial width $\Gamma(\psi(3770) \to {\rm non-}D\bar D) =
(2.8 \pm 1.8 \pm 2.4)$ MeV. Meanwhile we determine the observed cross section
for $non-D\bar D$ event production from $\psi(3770)$ decays to be $\sigma^{\rm
obs}(\psi(3770)\to non-D\bar D) = (0.72 \pm 0.46 \pm 0.62)$ nb.

for Run II of the DO experiment at the Fermilab Tevatron. QCD results include
dijet angular decorrelations and inclusive jet and dijet cross sections.

title:
Evidence for kappa Meson Production in J/psi -> bar{K}^*(892)^0K^+pi^-
  Process

abstract:
  Based on 58 million BESII J/psi events, the bar{K}^*(892)^0K^+pi^- channel in
K^+K^-pi^+pi^- is studied. A clear low mass enhancement in the invariant mass
spectrum of K^+pi^- is observed. The low mass enhancement does not come from
background of other J/psi decay channels, nor from phase space. Two independent
partial wave analyses have been performed. Both analyses favor that the low
mass enhancement is the kappa, an isospinor scalar resonant state. The average
mass and width of the kappa in the two analyses are 878 +- 23^{+64}_{-55}
MeV/c^2 and 499 +- 52^{+55}_{-87} MeV/c^2, respectively, corresponding to a
pole at (841 +- 30^{+81}_{-73}) - i(309 +- 45^{+48}_{-72}) MeV/c^2.


title: Top physics prospects at LHC

abstract:
  With a high instantaneous luminosity and the large top quark pair production
cross section, the Large Hadron Collider (LHC) will be a "top factory" allowing
the analysis of millions of top events. After a short description of the top
quark pair production mechanism and the cross section measurement, the accuracy
of the top mass measurement needed for a sound consistency check of the
Standard Model is briefly discussed. Different top mass measurement methods are
presented. The observability of the single top quark production is described.
Finally the observation of the Higgs boson produced in association with a top
quark pair is discussed.

spectrum. We assume three models for the form of the shape function;
exponential, gaussian and hyperbolic.

of this elusive state.


title:
Measurement of Double Charmonium Production in $e^+e^-$ Annihilations at
  $\sqrt{s}=10.6$ GeV

abstract:
  We study $e^+e^-\to J/\psi c\bar{c}$ by measuring the invariant mass
distribution recoiling against fully reconstructed $J/\psi$ decays, using 124
fb$^{-1}$ of data collected with a center-of-mass energy of 10.6 GeV with the
$BaBar$ detector. We observe signals for $\eta_c(1S)$, $\chi_{c0}$, and
$\eta_c(2S)$ in the recoil mass distribution, thus confirming previous
measurements. We measure $\sigma(e^+e^-\to J/\psi+c\bar{c}) {\cal B} (c\bar{c}
\to >2 \mathrm{charged})$ to be
  $17.6\pm2.8\textrm{(stat)}^{+1.5}_{-2.1}\textrm{(syst)}$ fb,
  $10.3\pm2.5\textrm{(stat)}^{+1.4}_{-1.8}\textrm{(syst)}$ fb, and
$16.4\pm3.7\textrm{(stat)}^{+2.4}_{-3.0}\textrm{(syst)}$ fb with
$c\bar{c}=\eta_c(1S)$, $\chi_{c0}$, and $\eta_c(2S)$, respectively.

Search for Large Extra Spatial Dimensions in Dimuon Production with the
  D0 Detector

abstract:
  We present the results of a search for the effects of large extra spatial
dimensions in $p{\bar p}$ collisions at $\sqrt{s} =$ 1.96 TeV in events
containing a pair of energetic muons. The data correspond to 246 \ipb of
integrated luminosity collected by the \D0 experiment at the Fermilab Tevatron
Collider. Good agreement with the expected background was found, yielding no
evidence for large extra dimensions. We set 95% C.L. lower limits on the
fundamental Planck scale between 0.85 TeV and 1.27 TeV within several
formalisms. These are the most stringent limits achieved in the dimuon channel
to date.


title:
Branching Fraction for B0 -> pi- l+ nu and Determination of |Vub| in
  Upsilon(4S) -> B0 B0bar Events Tagged by B0bar -> D(*)+ l- nubar

abstract:
  We report preliminary results from a study of the charmless exclusive
semileptonic decay B0 -> pi- l+ nu based on the data collected at the
Upsilon(4S) resonance using the BABAR detector at SLAC. The analysis uses
events in which the signal B meson recoils against a B meson that has been
reconstructed in a semileptonic decay B0bar -> D(*)+ l- nubar. We extract the
total branching fraction BF(B0 -> pi- l+ nu) = (1.03 +/- 0.25(stat.) +/-
0.13(syst.)) x 10^-4 and the partial branching fractions in three bins of q^2,
the invariant mass squared of the lepton-neutrino system. From the partial
branching fractions and theoretical predictions for the form factors, we
determine the magnitude of the CKM matrix element |Vub|. We find |Vub| = (3.3
+/- 0.4(stat.) +/- 0.2(syst.) +0.8/-0.4(FF)) x 10^-3, where the last error is
due to normalization of the form factor.


title:
Branching Fraction for B+ -> pi0 l+ nu, Measured in Upsilon(4S) -> B
  Bbar Events Tagged by B- -> D0 l- nubar (X) Decays

abstract:
  We report a preliminary branching fraction of (1.80 +/- 0.37(stat.) +/-
0.23(syst.)) x 10^-4 for the charmless exclusive semileptonic B+ -> pi0 l+ nu
decay, where l can be either a muon or an electron. This result is based on
data corresponding to an integrated luminosity of 81 fb^-1 collected at the
Upsilon(4S) resonance with the BABAR detector. The analysis uses BBbar events
that are tagged by a B meson reconstructed in the semileptonic B- -> D0 l-
nubar (X) decays, where X can be either a gamma or a pi0 from a D* decay.


title:
Search for Lepton-Flavor and Lepton-Number Violation in the Decay
  tau->lhh

abstract:
  A search for lepton-flavor and lepton-number violation in the decay of the
tau lepton into one charged lepton and two charged hadrons is performed using
221.4 $\mathrm{fb}^{-1}$ of data collected at an $e^+e^-$ center-of-mass energy
of 10.58 GeV with the BaBar detector at the PEP-II storage ring. In all 14
decay modes considered, the observed data are compatible with background
expectations, and upper limits are set in the range ${\cal B}(\tau\to\ell
hh')<(0.7-4.8)\times 10^{-7}$ at 90% confidence level.


title:
Tests of Lorentz violation in muon antineutrino to electron antineutrino
  oscillations

abstract:
  A recently developed Standard-Model Extension (SME) formalism for neutrino
oscillations that includes Lorentz and CPT violation is used to analyze the
sidereal time variation of the neutrino event excess measured by the Liquid
Scintillator Neutrino Detector (LSND) experiment. The LSND experiment,
performed at Los Alamos National Laboratory, observed an excess, consistent
with neutrino oscillations, of ${\bar\nu}_e$ in a beam of ${\bar\nu}_\mu$. It
is determined that the LSND oscillation signal is consistent with no sidereal
variation. However, there are several combinations of SME coefficients that
describe the LSND data; both with and without sidereal variations. The scale of
Lorentz and CPT violation extracted from the LSND data is of order $10^{-19}$
GeV for the SME coefficients $a_L$ and $E \times c_L$. This solution for
Lorentz and CPT violating neutrino oscillations may be tested by other short
baseline neutrino oscillation experiments, such as the MiniBooNE experiment.


title:
Charm Hadrons from Fragmentation and B decays in e+e- Annihilation at
  $\sqrt{s}=$10.6 GeV

abstract:
  We present an analysis of charm quark fragmentation at 10.6 GeV, based on a
data sample of 103 fb collected by the Belle detector at the KEKB accelerator.
We consider fragmentation into the main charmed hadron ground states, namely
\DZ, \DP, \Ds and \LC, as well as the excited states \DSZ and \DSP. The
fragmentation functions are important to measure as they describe processes at
a low energy scale, where calculations in perturbation theory lead to large
uncertainties. Fragmentation functions can also be used as input distributions
for Monte Carlo generators. Additionally, we determine the average number of
these charmed hadrons produced per B decay at the \Ys resonance and measure the
distribution of their production angle in \epem annihilation events and in B
decays.


title:
Measurement of the B+- --> rho+- pi0 Branching Fraction and Direct CP
  Asymmetry

abstract:
  An improved measurement of the process B+- --> rho+- pi0 is presented. The
data sample of 211/fb comprises 232 million Y(4S) --> BBbar decays collected
with the BaBar detector at the PEP-II asymmetric-energy B Factory at SLAC. The
yield and CP asymmetry are calculated using an extended maximum likelihood
fitting method. The branching fraction and asymmetry are found to be BR(B+- -->
rho+- pi0) = [10.0 +- 1.4 (stat) +- 0.9 (syst)]x 10^-6 and Acp(B+- --> rho+-
pi0) = -0.01 +- 0.13 (stat) +- 0.02 (syst), superseding previous measurements.
The statistical significance of the branching fraction is calculated to be
8.7sigma.


title: Search for the rare decay B0bar --> D*0 gamma

abstract:
  We report on a search for the rare decay B0bar --> D*0 gamma, which in the
standard model is dominated by W-exchange. The analysis is based on a data
sample comprising 87.8 x 10^6 BBbar pairs collected with the BABAR detector at
the PEP-II asymmetric-energy B Factory at SLAC. No significant signal is
observed, and an upper limit on the branching fraction of 2.5 x 10^{-5} at the
90% confidence level is obtained.


title: Charm and Beauty Production at HERA-B

abstract:
  The HERA-B experiment at DESY has acquired a data set of approximately
300,000 decays J/psi -> l+l- during its 2002/2003 data-taking period. These
data are used to analyze the production of heavy quarks in proton-nucleus
interactions at a center-of-mass energy of 41.6 GeV.
  In this article, preliminary results of two measurements are discussed, a
measurement of nuclear effects in the production of J/psi mesons and a
measurement of the b-bbar production cross section.


title:
Branching ratios and spectral functions of tau decays: final ALEPH
  measurements and physics implications

abstract:
  The full LEP-1 data set collected with the ALEPH detector at the $Z$ pole
during 1991-1995 is analysed in order to measure the $\tau$ decay branching
fractions. Extensive systematic studies are performed, in order to match the
large statistics of the data sample corresponding to over 300 000 measured and
identified $\tau$ decays. Branching fractions are obtained for the two leptonic
channels and eleven hadronic channels defined by their respective numbers of
charged particles and $\pi^0$'s. Using previously published ALEPH results on
final states with charged and neutral kaons, corrections are applied to the
hadronic channels to derive branching ratios for exclusive final states without
kaons. Thus the analyses of the full LEP-1 ALEPH data are combined to yield a
complete description of $\tau$ decays, encompassing 22 non-strange and 11
strange hadronic modes. Some physics implications of the results are given, in
particular related to universality in the leptonic charged weak current,
isospin invariance in $a_1$ decays, and the separation of vector and
axial-vector components of the total hadronic rate. Finally, spectral functions
are determined for the dominant hadronic modes and updates are given for
several analyses. These include: tests of isospin invariance between the weak
charged and electromagnetic hadronic currents, fits of the $\rho$ resonance
lineshape, and a QCD analysis of the nonstrange hadronic decays using spectral
moments, yielding the value $\alpha_s(m^2_\tau) = 0.340 \pm 0.005_{\rm exp} \pm
0.014_{\rm th}$. The evolution to the $Z$ mass scale yields $\alpha_s(M_Z^2) =
0.1209 \pm 0.0018$. This value agrees well with the direct determination from
the $Z$ width and provides the most accurate test to date of asymptotic freedom
in the QCD gauge theory.


title: Search for B --> Ds(*) Phi

abstract:
  We report on searches for B- --> Ds- Phi and B- --> Ds*- Phi. In the context
of the Standard Model, the branching fractions for these decays are expected to
be highly suppressed, since they proceed through annhilation of the b and u-bar
quarks in the B- meson. Our results are based on 234 million Upsilon(4S) --> B
Bbar decays collected with the BaBar detector at SLAC. We find no evidence for
these decays, and we set 90% confidence level upper limits on the branching
fractions BF(B- --> Ds- Phi) < 1.8x10^(-6) BF(B- --> Ds*- Phi) < 1.1x10^(-5).
These results are consistent with Standard Model expectations.

Search for First-Generation Scalar Leptoquarks in $\bm{p \bar{p}}$
  collisions at $\sqrt{s}$=1.96 TeV

abstract:
  We report on a search for pair production of first-generation scalar
leptoquarks ($LQ$) in $p \bar{p}$ collisions at $\sqrt{s}$=1.96 TeV using an
integrated luminosity of 203 $pb^{-1}$ collected at the Fermilab Tevatron
collider by the CDF experiment. We observe no evidence for $LQ$ production in
the topologies arising from $LQ \bar{LQ} \to eqeq$ and $LQ \bar{LQ} \to eq \nu
q$, and derive 95% C.L. upper limits on the $LQ$ production cross section. %as
a function of $\beta$, where $\beta$ is the branching fraction for $LQ \to eq$.
The results are combined with those obtained from a separately reported CDF
search in the topology arising from $LQ\bar{LQ} \to \nu q \nu q$ and 95% C.L.
lower limits on the LQ mass as a function of $\beta = BR(LQ \to eq) $ are
derived. The limits are 236, 205 and 145 GeV/c$^2$ for $\beta$ = 1, $\beta$ =
0.5 and $\beta$ = 0.1, respectively.


title: Search for nuclearites with the SLIM detector

abstract:
  We discuss the properties of cosmic ray nuclearites, from the point of view
of their search with large nuclear track detector arrays exposed at different
altitudes, in particular with the SLIM experiment at the Chacaltaya high
altitude lab (5290 m a.s.l.). We present calculations concerning their
propagation in the Earth atmosphere and discuss their possible detection with
CR39 and Makrofol nuclear track detectors.

Study of the process $e^+e^- \to \pi^+\pi^-$ in the energy region
  400<\sqrt[]{s}<1000 MeV

abstract:
  The cross section of the process e^+e^-\to \pi^+\pi^- was measured in the SND
experiment at the VEPP-2M collider in the energy region 400<\sqrt[]{s}<1000
MeV. This measurement was based on about 12.4 \times 10^6 selected collinear
events, which include 7.4\times 10^6 e^+e^-\to e^+e^-, 4.5\times 10^6
e^+e^-\to\pi^+\pi^- and 0.5\times 10^6 e^+e^-\to\mu^+\mu^- selected events. The
systematic uncertainty of the cross section determination is 1.3 %. The
\rho-meson parameters were determined: m_\rho=774.9\pm 0.4\pm 0.5 MeV,
\Gamma_\rho=146.5\pm 0.8\pm 1.5 MeV, \sigma(\rho\to\pi^+\pi^-)=1220\pm 7\pm 16
nb as well as the parameters of the G-parity suppressed decay
\omega\to\pi^+\pi^-: \sigma(\omega\to\pi^+\pi^-)=29.9\pm 1.4\pm 1.0 nb and
\phi_{\rho\omega} = 113.5\pm 1.3\pm 1.7 degree.


title: Evidence for an Anti-charmed Baryon State

abstract:
  We report on the observation of a narrow resonance in D^{*-}p and D^{*+} pbar
invariant mass combinations in deep-inelastic ep scattering at centre-of-mass
energies of 300 and 320 GeV at HERA. The mass of the resonance is measured to
be 3099 +- 3 (stat.) +- 5 (syst.) MeV, the Gaussian width of 12 +- 3 (stat.)
MeV is compatible with the experimental resolution. The state can be
interpreted as an anti-charmed baryon with minimal constituent quark
composition $uudd\bar c$, together with the charge conjugate.


title: Search for spontaneous muon emission from lead nuclei

abstract:
  We describe a possible search for muonic radioactivity from lead nuclei using
the base elements ("bricks" composed by lead and nuclear emulsion sheets) of
the long-baseline OPERA neutrino experiment. We present the results of a Monte
Carlo simulation concerning the expected event topologies and estimates of the
background events. Using few bricks, we could reach a good sensitivity level.


title: Observation of b --> d gamma and Determination of |V_td/V_ts|

abstract:
  We report the observation of the flavor-changing neutral current process b
--> d gamma using a sample of 386*10^6 B meson pairs accumulated by the Belle
detector at the KEKB e+ e- collider. We measure branching fractions for the
exclusive modes B- --> rho- gamma, B0bar --> rho0 gammaand B0bar --> omega
gamma. Assuming that these three modes are related by isospin, we find Br(B -->
(rho,omega) gamma) = (1.32 +0.34-0.31(stat.) +0.10-0.09(syst.)) * 10^-6 with a
significance of 5.1 sigma. This result is used to determine the ratio of CKM
matrix elements |V_td/V_ts| to be 0.199 +0.026-0.025(exp.) +0.018-0.015(theo.).


title: Measurements of B Decays to Two Kaons

abstract:
  We report measurements of B meson decays to two kaons using 250/fb of data
collected with the Belle detector at the KEKB asymmetric energy e+ e- collider.
We find evidence of signals in B+ -> K0(bar) K+ and B0 -> K0 K0(bar) with
significances of 3.0 sigma and 3.5 sigma, respectively. The corresponding
branching fractions are measured to be BF(B+ -> K0(bar) K+) = (1.0+-0.4+-0.1) x
10^-6 and Br(B0 -> K0 K0(bar)) = 0.8+-0.3+-0.1) x 10^-6. These decay modes are
examples of hadronic b -> d transitions. No signal is observed in the decay B0
-> K+ K- and we set an upper limit of 3.7 x 10^-7 at 90% confidence level.


title:
Observation of a Broad Structure in the $\pi^+\pi^-J/\psi$ Mass Spectrum
  around 4.26 GeV/$c^2$

abstract:
  We study initial-state radiation events, $e^+e^- \to
\gamma_{ISR}\pi^+\pi^-J/\psi$, with data collected with the BaBar detector. We
observe an accumulation of events near 4.26 GeV/$c^2$ in the invariant-mass
spectrum of $\pi^+\pi^-J/\psi$. Fits of the mass spectrum indicate that a broad
resonance with a mass of about 4.26 GeV/$c^2$ is required to describe the
observed structure. The presence of additional narrow resonances cannot be
excluded. The fitted width of the broad resonance is 50 to 90 MeV/$c^2$,
depending on the fit hypothesis.


title:
Measurement of Time-Dependent CP Asymmetries and the CP-Odd Fraction in
  the Decay B0->D*+D*-

abstract:
  We present an updated measurement of time-dependent \CP asymmetries and the
\CP-odd fraction in the decay $B^0 \to D^{*+}D^{*-}$ using $232 \times 10^{6}
\BB$ pairs collected by the \babar detector at the PEP-II $B$ factory. We
determine the \CP-odd fraction to be $0.125 \pm 0.044\stat \pm 0.007\syst$. The
time-dependent \CP asymmetry parameters $C_+$ and $S_+$ are determined to be
$0.06\pm 0.17\stat \pm 0.03\syst$ and $-0.75 \pm 0.25\stat \pm 0.03\syst$,
respectively. The Standard Model predicts these parameters to be 0 and
$-\stwob$, respectively, in the absence of penguin amplitude contributions.


title: Results from the BaBar Fully Inclusive Measurement of $B\to X_s\gamma$

abstract:
  We present preliminary results from a lepton-tagged fully-inclusive
measurement of $B \to X_{s}\gamma$ decays, where $X_{s}$ is any strange
hadronic state. Results are based on a BaBar data set of 88.5 million
$B\bar{B}$ pairs at the $\Upsilon(4S)$ resonance. We present a reconstructed
photon energy spectrum in the $\Upsilon(4S)$ frame, and partial branching
fractions above minimum reconstructed photon energies of 1.9, 2.0, 2.1 and 2.2
GeV. We then convert these to measurements of partial branching fractions and
truncated first and second moments of the true photon energy distribution in
the B rest frame, above the same minimum photon energy values. The full
correlation matrices between the first and second moments are included to allow
fitting to any parameterized theoretical calculation. We also measure the
direct CP asymmetry $A_{cp}(B \to X_{s+d}\gamma)$ (based on the charge of the
tagging lepton) above a reconstructed photon energy of 2.2 GeV


title: Measurement of CP Observables for the Decays B+/- --> D0_CP K*+/-

abstract:
  Using a sample of 232 million Upsilon(4S) --> B Bbar events collected with
the BABAR detector at the PEP-II B Factory in 1999-2004, we study B- --> D0
K*(892)- decays where K*- --> KS pi- and D0 --> K-pi+, K-pi+pi0, K-pi+pi+pi-
(non-CP final states); K+K-, pi+pi- (CP+ eigenstates); KSpi0, KSphi and KSomega
(CP- eigenstates). We measure four observables that are sensitive to the angle
gamma of the CKM unitarity triangle; the partial-rate charge asymmetries
A_CP+/- and the ratios of the B-decay branching fraction in CP+/- and non-CP
decays R_CP+/-:
  A_CP+ = -0.08 +/- 0.19 (stat.) +/- 0.08 (syst.)
  A_CP- = -0.26 +/- 0.40 (stat.) +/- 0.12 (syst.)
  R_CP+ = 1.96 +/- 0.40 (stat.) +/- 0.11 (syst.)
  R_CP- = 0.65 +/- 0.26 (stat.) +/- 0.08 (syst.)


title:
Study of B --> pi l nu and B --> rho l nu decays and determination of
  |Vub|

abstract:
  We present an analysis of exclusive charmless semileptonic B-meson decays
based on 83 million BBbar pairs recorded with the BABAR detector at the
Upsilon(4S) resonance. Using isospin symmetry, we measure branching fractions
B(B0 --> pi- l+ nu) = (1.38 +- 0.10 +- 0.16 +- 0.08) x 10^-4 and B(B0 --> rho-
l+ nu) = (2.14 +- 0.21 +- 0.48 +- 0.28) x 10^-4, where the errors are
statistical, experimental systematic, and due to form-factor shape
uncertainties. We compare the measured distribution in q^2, the
momentum-transfer squared, with theoretical predictions for the form factors
from lattice QCD and light-cone sum rules, and extract the
Cabibbo-Kobayashi-Maskawa (CKM) matrix element |V_{ub}| = (3.82 +- 0.14 +- 0.22
+- 0.11 +0.88 -0.52) x 10^-3 from B --> pi l nu, where the fourth error
reflects the uncertainty of the form-factor normalization.


title: Dalitz-plot analysis of the decays B+/- --> K+/- pi-/+ pi+/-

abstract:
  We report a Dalitz-plot analysis of the charmless hadronic decays of charged
B mesons to the final state K+/- pi-/+ pi+/-. Using a sample of 226.0 +/- 2.5
million BBbar pairs collected by the BaBar detector, we measure the magnitudes
and phases of the intermediate resonant and nonresonant amplitudes for both
charge conjugate decays. We present measurements of the corresponding branching
fractions and their charge asymmetries that supersede those of previous BaBar
analyses. We find the charge asymmetries to be consistent with zero.


title: Measurements of the rare decays B -> Kl+l- and B -> K*l+l-

abstract:
  We present measurements of the flavor-changing neutral current decays B ->
Kl+l- and B -> K*l+l-, where l+l- is either an e+e- or mu+mu- pair. The data
sample comprises 229 X 10^6 Y(4S) -> BBbar decays collected with the BaBar
detector at the PEP-II e+e- storage ring. We measure the branching fractions
BF(B -> Kl+l-) = (0.34 +- 0.07 +- 0.03) X 10^-6 and BF(B -> K*l+l-) =
(0.78^{+0.19}_{-0.17} +/- 0.12) X 10^-6, the direct CP asymmetries of these
decays, and the relative abundances of decays to electrons and muons.


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

abstract:
  The results on the measurements of the top-quark mass, based on the data
collected by the Tevatron experiments CDF and D{\O}at Fermilab during Run I
from 1992 to 1996, and Run II since 2001 are summarized. The combination of the
published Run I and preliminary Run II results, taking correlated uncertainties
properly into account, is presented. The resulting preliminary world average
for the mass of the top quark is: $\MT=174.3 \pm 3.4 \GeVc2$, where the total
error consists of a statistical part of $2.0 \GeVc2$ and a systematic part of
$2.8 \GeVc2$.


title: Search for solar axions: the CAST experiment at CERN

abstract:
  Hypothetical axion-like particles with a two-photon interaction would be
produced in the sun by the Primakoff process. In a laboratory magnetic field
they would be transformed into X-rays with energies of a few keV. The CAST
experiment at CERN is using a decommissioned LHC magnet as an axion helioscope
in order to search for these axion-like particles. The analysis of the 2003
data has shown no signal above the background, thus implying an upper limit to
the axion-photon coupling < 1.16*10^{-10} GeV^{-1} at 95% CL for m_{a} <~ 0.02
eV. The stable operation of the experiment during 2004 data taking allow us to
anticipate that this value will be improved. At the end of 2005 we expect to
start with the so-called second phase of CAST, when the magnet pipes will be
filled with a buffer gas so that the axion-photon coherence will be extended.
In this way we will be able to search for axions with masses up to 1 eV.


title: Measuring Mass and Cross Section Parameters at a Focus Point Region

abstract:
  The purpose of this study is to determine the experimental uncertainties in
measuring mass and cross section parameters of SUSY particles at a 500 GeV
Linear Collider. In this study SUSY is a point in the focus point region of
mSUGRA parameter space that is compatible with WMAP constraints on dark matter
relic density. At this study point the masses of the squarks and sleptons are
very heavy, and the only SUSY particles accessible at the Linear Collider would
be the three lightest neutralinos, and the two lightest charginos: nino1,
nino2, nino3, cino1+, cino2+, where nino1 is the lightest supersymmetric
particle (LSP). The charginos or neutralinos may be pair produced, and the
subsequent decay cascades to the LSP allow us to measure the SUSY couplings and
mass spectrum. We find that by looking for the signature 2 jets plus 2 leptons
plus missing energy we can determine the mass of the LSP to within 1 GeV
uncertainty and that the mass differences of nino2 and nino3 with the LSP mass
can be determined to better than 0.5 GeV.


title: A Precision Measurement of the Lambda_c Baryon Mass

abstract:
  The $\Lambda_c^+$ baryon mass is measured using $\Lambda_c^+\to\Lambda K^0_S
K^+$ and $\Lambda_c^+\to\Sigma^0 K^0_S K^+$ decays reconstructed in 232
fb$^{-1}$ of data collected with the BaBar detector at the PEP-II
asymmetric-energy $e^+e^-$ storage ring. The $\Lambda_c^+$ mass is measured to
be $2286.46\pm0.14\mathrm{MeV}/c^2$. The dominant systematic uncertainties
arise from the amount of material in the tracking volume and from the magnetic
field strength.


title: Neutrino-induced muons observed with MINOS

abstract:
  The Main Injector Neutrino Oscillation Search (MINOS) experiment's Far
Detector has been operational since July 2003, taking cosmic ray and
atmospheric neutrino data from its location in the Soudan Mine Underground Lab.
Numerous neutrino-induced muons have been observed. The detector's magnetic
field allows the first determination by a large underground detector of muon
charge and thus neutrino versus anti-neutrino on an event by event basis.


title: A Study of Production and Decays of Omega_c0 Baryons at BABAR

abstract:
  Production and decay of $\Omega_c^0$ baryons is studied with $\sim230
\mathrm{fb}^{-1}$ of data recorded with the BABAR detector at the PEP-II
$e^+e^-$ asymmetric-energy storage ring at SLAC. The $\Omega_c^0$ is
reconstructed through its decays into $\Omega^-\pi^+$,
$\Omega^-\pi^+\pi^+\pi^-$, and $\Xi^-K^-\pi^+\pi^+$ final states.
  The invariant mass spectra are presented and the signal yields are extracted.
Ratios of branching fractions are measured relative to the $\Omega^-\pi^+$ mode
\frac{{\cal B}(\Xi^-K^-\pi^+\pi^+)}{{\cal B}(\Omega^-\pi^+)}
  &= 0.31 \pm 0.15\mathrm{(stat.)}
  \pm 0.04\mathrm{(syst.)},
  \frac{{\cal B}(\Omega^-\pi^+\pi^+\pi^-)}{{\cal B}(\Omega^-\pi^+)}
  &< 0.30\qquad (90%\mathrm{CL}).
  The momentum spectrum (not corrected for efficiency) of $\Omega_c^0$ baryons
is extracted from decays into $\Omega^-\pi^+$, establishing the first
observation of $\Omega_c^0$ production from B decays.


title:
Measurement of the B+ --> p pbar K+ Branching Fraction and Study of the
  Decay Dynamics

abstract:
  With a sample of 232x10^6 Upsilon(4S) --> BBbar events collected with the
BaBar detector, we study the decay B+ --> p pbar K+ excluding charmonium decays
to ppbar. We measure a branching fraction Br(B+ --> p pbar
K+)=(6.7+/-0.5+/-0.4)x10^{-6}. An enhancement at low ppbar mass is observed and
the Dalitz plot asymmetry suggests dominance of the penguin amplitude in this B
decay. We search for a pentaquark candidate Theta*++ decaying into pK+ in the
mass range 1.43 to 2.00 GeV/c2 and set limits on Br(B+ -->
Theta*++pbar)xBr(Theta*++ --> pK+) at the 10^{-7} level.


title: Transversity measurements at HERMES

abstract:
  Azimuthal single-spin asymmetries (SSA) in semi-inclusive electroproduction
of charged pions in deep-inelastic scattering (DIS) of positrons on a
transversely polarised hydrogen target are presented. Azimuthal moments for
both the Collins and the Sivers mechanism are extracted. In addition the
subleading-twist contribution due to the transverse spin component from SSA on
a longitudinally polarised hydrogen target is evaluated.


title:
Search for the Theta(1540)+ pentaquark using kaon secondary interactions
  at Belle

abstract:
  Using kaon secondary interactions in the material of the Belle detector, we
search for both inclusive and exclusive production of the Theta(1540)+. We set
an upper limit of 2.5% at the 90% C.L. on the ratio of the Theta(1540)+ to
Lambda(1520) inclusive production cross sections. We also search for the
Theta(1540)+ as an intermediate resonance in the charge exchange reaction K+ n
-> p Ks. An upper limit of Gamma(Theta+)<0.64MeV at the 90% C.L. at
m(Theta+)=1.539MeV is set. These results are obtained from a 397/fb data sample
collected with the Belle detector near the Upsilon(4S) resonance, at the KEKB
asymmetric energy e+e- collider.


title: Prospects for Low-Energy Antiproton Physics at Fermilab

abstract:
  Fermilab has long had the world's most intense antiproton source. Despite
this, opportunities for low-energy antiproton physics at Fermilab have in the
past been limited and--with the antiproton source now exclusively dedicated to
serving the needs of the Tevatron Collider--are currently nonexistent. While
the future of antiproton physics at Fermilab is uncertain, the anticipated
shutdown of the Tevatron in about 2009 presents the opportunity for a
world-leading low-energy antiproton program. We summarize the current status of
the Fermilab antiproton facility and review some current topics in hyperon
physics as examples of what might be achievable.


title:
Measurement of Time-dependent CP-Violating Asymmetries in B0 -> K+K-K0L
  Decays

abstract:
  We present preliminary measurements of the CP asymmetry parameters and CP
content in B0 --> K+K-K0L decays, with B0 --> phi K0L events excluded. In a
sample of 227 M B bar B pairs collected by the BaBar detector at the PEP-II B
Factory at SLAC, we find the CP parameters to be S = 0.07 +/- 0.28 (stat)
{+0.11} {-0.12} (syst)
  C = 0.54 +/- 0.22 (stat) {+0.08} {-0.09} (syst) where the first error is
statistical and the second is systematic. Estimating the fraction of CP-odd
final states from angular moments analysis in the K+K-K0S CP-conjugate final
state, f_{odd} (K+K-K0L) = 0.92 +/- 0.07 (stat) +/- 0.06 (syst) we determine
sin 2beta_{eff} = 0.09 +/- 0.33, (stat) {+0.13} {-0.14} (syst) +/- 0.10 (syst
CP-cont)


title:
Measurement of the Partial Branching Fraction for Inclusive Charmless
  Semileptonic B Decays and Extraction of $|V_{ub}|$

abstract:
  Charmless semileptonic decays, ${\bar{B}} \to X_u \ell \bar{\nu}$, are
studied in a sample of 232 million $B\bar{B}$ decays recorded with the BaBar
detector, in events where the decay of the second $B$ meson is fully
reconstructed. Inclusive charmless decays are selected in kinematic regions
where the dominant background from semileptonic B decays to charm is reduced by
requirements on the hadronic mass $M_X$ and the momentum transfer $q^2$. The
partial branching fraction for ${\bar{B}} \to X_u \ell \bar{\nu}$ decays for
$M_X<1.7$ GeV/c^2 and $q^2>8$ Gev^2/c^4 is measured to be
$\Delta{\cal{B}}({\bar{B}} \to X_u \ell \bar{\nu}) = (0.87 \pm 0.09_{\rm
stat}\pm 0.09_{\rm sys}\pm 0.01_{\rm th})\times 10^{-3}$. The CKM matrix
element $|V_{ub}|$ is determined by using theoretical calculations of phase
space acceptances. Theoretical uncertainties in this extrapolation are reduced
by using the inclusive $b \to s \gamma$ photon spectrum and moments of the $b
\to c \ell \bar{\nu}$ lepton energy and hadronic invariant mass.


title: The MINOS Detectors

abstract:
  The Main Injector Neutrino Oscillation Search (MINOS) experiment's primary
goal is the precision measurement of the neutrino oscillation parameters in the
atmospheric neutrino sector. This long-baseline experiment uses Fermilab's NuMI
beam, measured with a Near Detector at Fermilab, and again 735 km later using a
Far Detector in the Soudan Mine Underground Lab in northern Minnesota. The
detectors are magnetized iron/scintillator calorimeters. The Far Detector has
been operational for cosmic ray and atmospheric neutrino data from July of
2003, the Near Detector from September 2004, and the NuMI beam started in early
2005. This poster presents details of the two detectors.


title:
Observation of a new charmonium state in double charmonium production in
  e+ e- annihilation at \sqrt{s} ~ 10.6 GeV

abstract:
  We report the first observation of a new charmonium state at a mass of
$(3.943 \pm 0.006 \pm 0.006) {GeV}/c^2$. This state, called X(3940), is
observed in the process $e^+ e^- \to J/\psi X(3940)$ in the spectrum of masses
recoiling against a reconstructed $J/\psi$. We also observe the decay of the
X(3940) into $D^* \bar{D}$ and measure the intrinsic width of this state to be
less than $52 MeV/c^2$ at the 90% C.L. These results are obtained from a $350
fb^{-1}$ data sample collected with the Belle detector near the $\Upsilon(4S)$
resonance, at the KEKB asymmetric energy $e^+ e^-$ collider.


title: Search for D^0-\bar{D^0} mixing using semileptonic decays at Belle

abstract:
  A search for mixing in the neutral D meson system has been performed using
semileptonic D^0 \to K^(*)- e^+ nu decays. Neutral D mesons from D^*+ \to D^0
pi+ decays are used; the flavor at production is tagged by the charge of the
slow pion. The measurement is performed using 253 fb^-1 of data recorded by the
Belle detector. From the yield of right-sign and wrong-sign decays arising from
non-mixed and mixed events, respectively, we estimate the upper limit of the
time-integrated mixing rate to be r_D < 1.0 x 10^-3 at 90 % C.L.


title: Charm Physics at BaBar

abstract:
  Large production of the $\ccbar$ pairs and high integrated luminosity make
the PEPII B-Factory, an excellent place for studying the charm hadrons. In this
paper, we present a few of the most recent results from the BaBar collaboration
in the charm sector.


title: ZEUS Results

abstract:
  Several results from the ZEUS Collaboration were presented at this Workshop.
The highlights are presented in this summary, and include results from NLO QCD
fits and determination of alphas, from forward jets and diffractive final
states, from pentaquarks and searches and from heavy flavour production. Also
the first results from the analysis of the HERA II e+p/e-p data are shown.


title:
Evidence for B+ -> K0barK+ and B0 -> K0K0bar, and Measurement of the
  Branching Fraction and Search for Direct CP Violation in B+ -> K0pi+

abstract:
  We present evidence for the b -> d penguin-dominated decays B+ -> K0barK+ and
B0 -> K0K0bar with significances of 3.5 and 4.5 standard deviations,
respectively. The results are based on a sample of 227 million Y(4S) -> BBbar
decays collected with the BaBar detector at the PEP-II asymmetric-energy e+e-
collider at SLAC. We measure the branching fractions Br(B+ -> K0barK+) = (1.5
+- 0.5 +- 0.1) x 10^{-6} (< 2.4 x 10^{-6}) and Br(B0 -> K0K0bar) =
(1.19^{+0.40}_{-0.35} +- 0.13) x 10^{-6}, where the uncertainties are
statistical and systematic, respectively, and the upper limit on the branching
fraction for K0barK+ is at the 90% confidence level. We also present improved
measurements of the charge-averaged branching fraction Br(B+ -> K0pi+) = (26.0
+- 1.3 +- 1.0) x 10^{-6} and CP-violating charge asymmetry A_CP(K0pi+) = -0.09
+- 0.05 +- 0.01, where the uncertainties are statistical and systematic,
respectively.

Structure functions and parton distribution functions at the HERA ep
  collider

abstract:
  Recent results on structure functions and parton distribution functions at
HERA are presented. Results on the measurements of the structure functions F2,
FL and F3 will be covered, as well as the results of the most recent QCD fits
to determine the PDFs of the proton.


title: Amplitude Analysis of the Decay B+- -> pi+- pi+- pi-+

abstract:
  We present a Dalitz-plot analysis of charmless B+- decays to the final state
pi+- pi+- pi-+ using 210 fb^-1 of data recorded by the BABAR experiment at
sqrt(s) = 10.58 GeV. We measure the branching fractions B(B+- -> pi+- pi+-
pi-+) = (16.2 +- 1.2 +- 0.9) x 10^-6 and B(B+- -> rho^0(770) pi+-) = (8.8 +-
1.0 +- 0.6 +0.1-0.7) x 10^-6. Measurements of branching fractions for the
quasi-two-body decays B+- -> rho^0(1450) pi+-, B+- -> f_0(980) pi+- and B+- ->
f_2(1270) pi+- are also presented. We observe no charge asymmetries for the
above modes, and there is no evidence for the decays B+- -> chic0 pi+-, B+- ->
f_0(1370) pi+- and B+- -> sigma pi+-.


title: Dalitz Plot Analysis of D0-->K0bar K+ K-

abstract:
  A Dalitz plot analysis of approximately 12500 D0 events reconstructed in the
hadronic decay D0-->K0bar K+ K- is presented. This analysis is based on a data
sample of 91.5 fb-1 collected with the BaBar detector at the PEP-II
asymmetric-energy e+ e- storage rings at SLAC running at center-of-mass
energies on and 40 MeV below the Y4S resonance. The events are selected from e+
e- --> c cbar annihilations using the decay D*+ --> D0 pi+. The following ratio
of branching fractions has been obtained: BR = Gamma(D0-->K0bar K+
K-)/Gamma(D0-->K0bar pi+ pi-) = (15.8+/-0.1(stat.)+/-0.5(syst.)x 10-2 Estimates
of fractions and phases for resonant and non-resonant contributions to the
Dalitz plot are also presented. The a0(980)-->K Kbar projection has been
extracted with little background. A search for CP asymmetries on the Dalitz
plot has been performed.


title: Pentaquarks and new hadron spectroscopy at BaBar

abstract:
  Recent results on the search for pentaquarks and on charmonium spectroscopy
at BaBar are reviewed. The latter includes the observation of the puzzling new
state X(3872) -> J/psi pi+ pi- in B decays, and the searches for X(3872) in
two-body B decays and initial state radiation events.


title: Charm physics at Belle

abstract:
  This talk reviews an unrepresentative selection of Belle's open-charm and
charmonium analyses, focussing on new developments and topics of interest to
the DIS community. Highlights include an X(3872) analysis favoring J^PC = 1++,
and the D0-D*0bar bound-state interpretation.


title: Observation of B0 Meson decays to a1(1260) pi

abstract:
  We present preliminary measurements of the B meson decay B0 -> a1(1260)+ pi-,
with a1(1260)+ --> pi+ pi+ pi-. The data were recorded with the BABAR detector
at PEP II and correspond to 218 million BBbar pairs produced in e+e-
annihilation through the Upsilon(4S) resonance. We find the branching fractions
B(B0 -> a1(1260)+ pi-) = (40.2 +/- 3.9 +/- 3.9) x 10^-6. The fitted values of
the a1(1260) parameters are m_a1 = 1.22 +/- 0.02 GeV/c^2 and Gamma_a1= 423 +/-
50 MeV/c^2


title: Observation of Ds1(2536)+ -> D+ pi- K+

abstract:
  We report the observation of the decay Ds1(2536)+ -> D+ pi- K+. We also
measure the helicity angle distributions in the decay Ds1(2536)->D*+ K0S and
thus constrain the contributions and the phase difference of D and S wave
amplitudes in this decay. The results are based on a 281 fb^-1 data sample
collected with the Belle detector near the Y(4S) resonance, at the KEKB
asymmetric energy e+e- collider.
