title: Measurement of Branching Ratios for $\eta_c$ Hadronic Decays

abstract:
  In a sample of 58 million $J/\psi$ events collected with the BES II detector,
the process J/$\psi\to\gamma\eta_c$ is observed in five decay channels: $\eta_c
\to K^+K^-\pi^+\pi^-$, $\pi^+\pi^-\pi^+\pi^-$, $K^\pm K^0_S \pi^\mp$ (with
$K^0_S\to\pi^+\pi^-$), $\phi\phi$ (with $\phi\to K^+K^-$) and $p\bar{p}$. From
these signals, we determine $Br(J/\psi\to\gamma\eta_c)\times Br(\eta_c\to
K^+K^-\pi^+\pi^-)$ $=(1.5\pm0.2\pm0.2)\times10^{-4}$,
$Br(J/\psi\to\gamma\eta_c)\times Br(\eta_c\to \pi^+\pi^-\pi^+\pi^-)$
$=(1.3\pm0.2\pm0.4)\times10^{-4}$, $Br(J/\psi\to\gamma\eta_c)\times
Br(\eta_c\to K^\pm K_{S}^{0}\pi^\mp)$ $=(2.2\pm0.3\pm0.5)\times10^{-4}$,
$Br(J/\psi\to\gamma\eta_c)\times Br(\eta_c\to \phi\phi)$
$=(3.3\pm0.6\pm0.6)\times10^{-5}$ and $Br(J/\psi\to\gamma\eta_c)\times
Br(\eta_c\to p\bar{p})$ $=(1.9\pm0.3\pm0.3)\times10^{-5}$.

Muon energy reconstruction in ANTARES and its application to the diffuse
  neutrino flux

abstract:
  The European collaboration ANTARES aims to operate a large neutrino telescope
in the Mediterranean Sea, 2400 m deep, 40 km from Toulon (France). Muon
neutrinos are detected through the muon produced in charged current
interactions in the medium surrounding the detector. The Cherenkov light
emitted by the muon is registered by a 3D photomultiplier array. Muon energy
can be inferred using 3 different methods based on the knowledge of the
features of muon energy losses.They result in an energy resolution of a factor
\~ 2 above 1 TeV. The ANTARES sensitivity to diffuse neutrino flux models is
obtained from an energy cut, rejecting most of the atmospheric neutrino
background which has a softer spectrum. Fake upgoing events from downgoing
atmospheric muons are rejected using dedicated variables. After 1 year of data
taking, the ANTARES sensitivity is E^2 dF/dE < 8 10^-8 GeV cm^-2 s^-1 sr^-1 for
a 10 string detector and an E^-2 diffuse flux spectrum.


title: Heavy flavour production with leptons and hadrons

abstract:
  The production of charm and beauty quarks in $\gamma \gamma$ collisions at
LEP, $ep$ collisions at HERA and $p \bar{p}$ collisions at the Tevatron is
discussed. The comparison with predictions of next-to-leading-order QCD and the
issues it raises are detailed. In particular, the strengths and weaknesses of
the measurements and predictions are discussed.


title: ZEUS results on high Q^2 DIS cross sections and QCD fits

abstract:
  Single and double differential cross sections ds/dQ^2, ds/dx, ds/dy and
d^2s/dQ^2dx of the inclusive neutral current (NC) measurement from the 98/99
e^-p and the charged current (CC) measurement from the 99/00 e^+p data sets are
presented. With the previously published e^+p NC ZEUS measurement xF_3 and
xG_3, and with the e^-p CC ZEUS measurement F_2^CC are extracted. The results
are compared to the prediction of the Standard Model using parton density
functions of the ZEUS next-to-leading-order QCD analysis which is reviewed.


title: Measurements of sin(2 beta) in B decays

abstract:
  I describe the experimental determination of the CKM angle beta from
measurements of the decay time separation delta t between B0 mesons produced as
B Bbar pairs in e+e- annihilation. The current results from leading and
non-leading decay modes are presented and compared.


title: Measurement of the atmospheric muon spectrum from 20 to 2000 GeV

abstract:
  The atmospheric muon spectrum between 20 and 2000 GeV was measured with the
L3 magnetic muon spectrometer for zenith angles ranging from 0 to 58 degrees.
Due to the large data set and the good detector resolution, a precision of 2.6%
at 100 GeV was achieved for the absolute normalization of the vertical muon
flux. The momentum dependence of the ratio of positive to negative muons was
obtained between 20 and 630 GeV.


title: Jet Physics at the Tevatron

abstract:
  Results are presented from analyses of jet data produced in pbarp collisions
at $\sqrt{s}$ = 1960 GeV collected with the DZero and CDF detectors during
2002--03 at the Fermilab Tevatron
  Collider. Preliminary measurements of the inclusive jet cross section, the
dijet mass spectrum, and jet structure are presented.


title: Open charm production in DIS at HERA

abstract:
  An overview of recent HERA results on inclusive production of D* mesons in
deep inelastic scattering is given.


title: B Lambda_b and Charm Results from the Tevatron

abstract:
  Recent results on $B_d$, $B_u^{\pm}$, $B_s$, $\Lambda_b$ and Charm hadrons
are reported from $\approx$ 75pb$^{-1}$ and $\approx$ 40 pb$^{-1}$ of data
accumulated at the upgraded CDF and D0 experiments at the Fermilab Tevatron
$\bar{p}-p$ collider, during Run-II. These include lifetime and mass
measurements of $B$ and Charm hadrons, searches for rare decays in charm and
$B$ hadrons and CP-violation in Charm decays. Results relevant to CP-violation
in B-decays are also reported.


title: Observation of radiative B -> phi K gamma decays

abstract:
  The radiative decay $B \to \phi K \gamma$ is observed for the first time. The
branching fraction for the charged $B^- \to \phi K^- \gamma$ decay mode is
measured to be ${\cal B}(B^- \to \phi K^- \gamma) = (3.4 \pm 0.9 \pm 0.4)
\times 10^{-6}$. The photon energy distribution for the $B^- \to \phi K^-
\gamma$ decay is presented. The signal for the neutral $\bar{B}^0 \to \phi
\bar{K}^0 \gamma$ decay mode is not statistically significant and an upper
limit, ${\cal B}(\bar{B}^0 \to \phi \bar{K}^0 \gamma) < 8.3 \times 10^{-6}$ at
$90% {\rm CL}$, is set. The analysis is based on a dataset of 90 fb$^{-1}$
collected by the Belle experiment at the $e^+ e^-$ asymmetric collider KEKB.


title: Katrin - Direct Measurement of Neutrino Masses in the Sub-Ev Region

abstract:
  The \underline{KA}rlsruhe \underline{TRI}tium \underline{N}eutrino Mass
Experiment is a next generation tritium beta decay experiment designed to reach
a sensitivity of $0.2~ \mathrm{eV}/\mathrm{c}^2$. KATRIN will allow to
investigate the role of the neutrino hot dark matter in the evolution of large
scale structures of the universe and will also allow to discriminate between
so-called hierarchical and quasi-degenerated neutrino mass models. The status
of the first components of the final KATRIN setup will be shown.


title: Muon g-2

abstract:
  The muon g-2 collaboration has measured the anomalous magnetic g value of the
positive muon to within a relative uncertainty of 0.7 parts per million. The
result, a_{\mu^+} = 11 659 204(7)(5) x 10^{-10} is in good agreement with the
preceding data on a_{\mu^+} and a_{\mu^-} and has about twice smaller
uncertainty. The measurement tests standard model theory, which at the level of
the experimental uncertainty involves quantum electrodynamics, quantum
chromodynamics, and electroweak interaction in significant ways. The analysis
of the anomalous magnetic g value of the negative muon is well underway.


title: Measurement of inclusive jet cross-sections at low Q^2 at HERA

abstract:
  The single-inclusive cross-section for jet production in deep inelastic e-p
scattering (DIS) at HERA is measured for photon virtualities Q^2 between 5 and
100 GeV^2, differentially in Q^2, in transverse jet energy E_T, in E_T^2/Q^2
and in pseudorapidity eta_LAB. In most of the phase space these data are well
described by QCD calculations in next-to-leading order (NLO) using a
renormalization scale mu_R=E_T. Significant discrepancies are observed only for
jets in the proton beam direction with E_T below 20 GeV and Q^2 below 20 GeV^2.


title: Lepton Dipole Moments

abstract:
  From the famous experiments of Stern and Gerlach to the present, measurements
of magnetic dipole moments, and searches for electric dipole moments of
``elementary'' particles have played a major role in our understanding of
sub-atomic physics. In this talk I discuss the progress on measurements and
theory of the magnetic dipole moments of the electron and muon. I also discuss
a new proposal to search for a permanent electric dipole moment (EDM) of the
muon and put it into the more general context of other EDM searches.


title:
Precise Measurement of the Solar Neutrino Day/Night and Seasonal
  Variation in Super-Kamiokande-I

abstract:
  The time variation of the elastic scattering rate of solar neutrinos with
electrons in Super-Kamiokande-I was fit to the variations expected from active
two-neutrino oscillations. The best fit in the Large Mixing Angle solution has
a mixing angle of tan^2theta=0.55 and a mass squared difference of
Deltam^2=6.3times10^-5eV^2 between the two neutrino mass eigenstates. The
fitted day/night asymmetry of -1.8+-1.6(stat)+1.3-1.2(syst)% has improved
statistical precision over previous measurements and agrees well with the
expected asymmetry of -2.1%.


title:
Final State Correlations at LEP 2: Bose-Einstein Correlations and the W
  Mass

abstract:
  Recent experimental results on Bose-Einstein correlations are presented.
Emphasis will be put on the measurement of between-W correlations in WW events
at LEP 2.


title: A Study of W+W-gamma Events at LEP

abstract:
  A study of W+W- events accomanied by hard photon radiation produced in e+e-
collisions at LEP is presented. Events consistent with being two on-shell W
bosons and an isolated photon are selected from 681 pb^-1 of data recorded at
180 GeV < sqrt(s) < 209 GeV. For these data, 187 W+W- candidates are selected
with photon energies greater than 2.5 GeV. The selected events are used to
determine the W+ W- gamma cross section at five values of sqrt(s). The results
are consistent with the Standard Model expectation. These data provide
constraints on the related O(alpha) systematic uncertainties on the measurement
of the W boson mass at LEP. Finally, the data are used to derive 95% C.L. upper
limits on possible anomalous contributions to the W+ W- gamma gamma and W+ W-
Z0 gamma vertices.


title:
Search for Anomalous Production of Di-lepton Events with Missing
  Transverse Momentum in e+e- Collisions at sqrt(s) = 183-209 GeV

abstract:
  In total 1317 di-lepton events with significant missing transverse momentum
were identified in a total data sample of 680 pb-1 collected at e+e-
centre-of-mass energies ranging from 183 GeV to 209 GeV. The number of
di-lepton events, the dependence on centre-of-mass energy, and the event
properties are consistent with expectations from Standard Model processes,
predominantly W+W- production with both W bosons decaying leptonically. This
topology is also an experimental signature for the pair production of new
particles that decay to a charged lepton accompanied by one or more invisible
particles. No evidence for new phenomena is apparent. Upper limits are
presented on the production cross-section multiplied by the relevant branching
ratio squared for sleptons, leptonically decaying charginos and charged Higgs
bosons. Mass limits are also given.


title: Heavy Quarkonia Spectroscopy and Decays

abstract:
  The experimental status of stable bound states made out of heavy quarks is
reviewed. The need for a way to deal with the non-perturbative transitions
involved calls for precision measurements on one hand, and for discovery of as
yet undetected states to confirm predictions on the other. In this article,
recent experimental contributions to heavy quarkonia spectroscopy and decay
will be reviewed, mostly from data analyzed by the BES and CLEO collaborations.
  The most dramatic recent discoveries include the detection of the first
stable L=2 state, and a first non-pionic hadronic transition in the Upsilon
system, and a first measurement of chi_cJ --> Lambda Lambdabar. Scans of the
psi' and Upsilon(1,2,3S) resonances are used to add information on partial and
total decay widths.

Results of the experiment on investigation of Germanium-76 double beta
  decay. Experimental data of Heidelberg-Moscow collaboration November 1995 -
  August 2001

abstract:
  On the termination of the Heidelberg-Moscow double-beta decay of Germanium-76
experi-ment, the analysis of the obtained data is presented. The value of the
half-life for two-neutrino double beta decay (2b2n mode) and limitation of the
half-life for neutrinoless dou-ble beta decay (2b0n mode) are given. The
results were presented at NANP2003, Dubna, June, 24.


title:
Measurement of Time-Dependent CP Asymmetry in $B^0\to D^{(*)\pm}\pi^\mp$
  Decays and Constraints on $sin(2\beta+\gamma)$

abstract:
  We present a measurement of time-dependent CP-violating asymmetries in fully
reconstructed $B^0->D^{(*)\pm}\pi^\mp$ decays in a data sample of approximately
88 million $Y(4S)\to B\bar{B}$ decays collected with the BaBar detector at the
PEP-II asymmetric-energy B factory at SLAC. We interpret the results in terms
of the angles of the Cabibbo-Kobayashi-Maskawa unitarity triangle, and find
$|sin(2\beta+\gamma)|>0.69$ at 68% confidence level. We exclude the hypothesis
of no CP-violation ($sin(2\beta+\gamma) = 0$) at 83% confidence level.


title: CLEO results on |V_cb| and |V_ub|

abstract:
  I report results from the CLEO collaboration on semileptonic B decays,
highlighting measurements of the Cabibbo-Kobayashi-Maskawa matrix elements
|V_cb| and |V_ub|. I describe the techniques used to obtain the recent
improvements in precision for these measurements, including the use of the b ->
s gamma photon spectrum to reduce hadronic uncertainties in semileptonic B
decays.


title: High statistics study of the K- -> pi0 e- nu decay

abstract:
  The decay K- -> pi0 e- nu has been studied using in-flight decays detected
with the "ISTRA+" spectrometer working at the 25 GeV negative secondary beam of
the U-70 PS. About 550K events were used for the analysis. The lambda+
parameter of the vector form-factor has been measured: lambda+ = 0.0286 +-
0.0008 (stat) +- 0.0006(syst). The limits on the possible tensor and scalar
couplings have been obtained: f(T)/f+(0)=0.021 +0.064 -0.075 (stat) +-
0.026(syst) ; f(S)/f+(0)=0.002 +0.020 -0.022 (stat) +- 0.003(syst)


title:
Measurement of the Decay Rate of Xi_c^0 --> pK^-K^-pi^+ Relative to
  Xi_c^0 --> Xi^-pi^+

abstract:
  Using the CLEOIII detector at CESR, we have measured the branching ratio of
the decay Xic0 to pK-K-pi+ relative to Xic0 to Xi- pi+. We find B(Xic0 to
pK-K-pi+)/B(Xic0 to Xi-pi+)= 0.35+/-$0.08(stat)+/-0.05(syst). In the resonant
substructure of this mode, we find evidence for Xi_c0 decays to p K*(890)K-,
and measure B(Xic0 to p K*(890) K^-).B(K*(890) to K-pi+) /B(Xic0 to
Xi-pi+)=0.14+/-0.04(stat)+/-0.02(syst) and B(Xic0 to pK-K-pi+)/B(Xic0 to
Xi-pi+)=0.21+/-0.05(stat)+/-0.03(syst) for the non-resonant Xic0 decays
pK-K-pi+ decays.


title: A Cicerone for the Physics of Charm

abstract:
  After briefly recapitulating the history of the charm quantum number we
sketch the experimental environments and instruments employed to study the
behaviour of charm hadrons and then describe the theoretical tools for treating
charm dynamics. We discuss a wide range of inclusive production processes
before analyzing the spectroscopy of hadrons with hidden and open charm and the
weak lifetimes of charm mesons and baryons. Then we address leptonic, exclusive
semileptonic and nonleptonic charm decays. Finally we treat $D^0 - \bar D^0$
oscillations and CP (and CPT) violation before concluding with some comments on
charm and the quark-gluon plasma. We will make the case that future studies of
charm dynamics -- in particular of CP violation -- can reveal the presence of
New Physics. The experimental sensitivity has only recently reached a level
where this could reasonably happen, yet only as the result of dedicated
efforts.
  This review is meant to be both a pedagogical introduction for the young
scholar and a useful reference for the experienced researcher. We aim for a
self-contained description of the fundamental features while providing a guide
through the literature for more technical issues.


title: First observation of the KS->pi0 gamma gamma decay

abstract:
  Using the NA48 detector at the CERN SPS, 31 KS->pi0 gamma gamma candidates
with an estimated background of 13.7 +- 3.2 events have been observed. This
first observation leads to a branching ratio of BR(KS->pi0 gamma gamma) = (4.9
+- 1.6(stat) +- 0.9(syst)) x 10^-8 in agreement with Chiral Perturbation theory
predictions.


title:
Results from the ICARUS T600 module - A measurement of the muon decay
  spectrum

abstract:
  We have studied the muon decay energy spectrum from a sample of stopping muon
events acquired during the test run of the ICARUS T600 prototype. This detector
allows the spatial reconstruction of the events with fine granularity, hence
the precise measurement of the muon range and dE/dx with high sampling rate.
This information is used to compute the correction factors needed for the
calorimetric reconstruction. The Michel rho parameter is then measured by
comparison of the experimental and Monte Carlo simulated muon decay spectra,
obtaining rho = 0.72 +/- 0.06 (stat) +/- 0.08 (syst).


title: Modeling Neutrino Quasielastic Cross Sections on Nucleons and Nuclei

abstract:
  We calculate the total and differential quasielastic cross sections for
neutrino and antineutrino scattering on nucleons using up to date fits to the
nucleon elastic electromagnetic form factors $G_E^p$, $G_E^n$, $G_M^p$,
$G_M^n$, and $F_A$ and pseudoscalar form factors. We compare predictions of the
cross sections for nucelons and nuclei to experimental data.


title:
Measurements of branching fractions in B -> phi K and B -> phi pi and
  search for direct CP violation in B+/- -> phi K+/-

abstract:
  We present measurements of branching fractions in the b -> s s-bar s
penguin-dominated decays B+ --> phi K+ and B0 --> phi K0 in a sample of
approximately 89 million BBbar pairs collected by the BaBar detector at the
PEP-II asymmetric-energy B-meson factory at SLAC. We determine B(B+ --> phi K+)
= (10.0 +0.9 -0.8 +/- 0.5) x 10^{-6} and B(B0 --> phi K0) = (8.4 +1.5 -1.3 +/-
0.5) x 10^{-6}. Additionally, we measure the CP-violating charge asymmetry ACP
(B+/- --> phi K+/-) = 0.04 +/- 0.09 +/- 0.01, with a 90% confidence interval of
[-0.10, 0.18], and set an upper limit B(B+ --> phi pi+) < 0.41 x 10^{-6} (at
the 90% confidence level).


title: New Charm(onium) Results from CDF

abstract:
  After many upgrades to the CDF detector and to the accelerator complex, Run
II began in April 2001. The new detector has improved capabilities for charm
physics, and first results from the analysis of early Tevatron Run II data are
reported here.


title: Relevant results from the NA48 experiment

abstract:
  We report relevant results from NA48 experiment at CERN SPS. NA48 was
proposed in 1990 \cite{proposal} to study direct CP violation in $K^0\to\pi\pi$
to a level of accuracy sufficient to resolve the inconclusive status left by
the previous measurements performed by NA31 \cite{NA31} and E731 \cite{E731}.
In 2002 NA48 published the final result \cite{NA48epsoeps}. Small modification
to the experimental setup have allowed NA48 to go forward with an extensive
investigation of $K^0$ rare decays and hyperon decays. Some results are already
available and reported here together with the final CP violation measurement.


title: Observation of New Narrow D_s states

abstract:
  The BABAR experiment has discovered a new narrow state, D^*_{sJ}(2317)^+,
near 2.32 GeV in the inclusive D_s^+ pi^0 invariant mass distribution from
e^+e^- annihilation data at energies near 10.6 GeV. The same experiment has
also shown evidence for structure in the 2.46 GeV region in the D^*_s(2112)^+
pi^0 mass spectrum. These discoveries have triggered several experiments in a
search for new states coupled to the D_s^+ meson which confirmed the existence
of D^*_{sJ}(2317)^+ together with D_{sJ}(2458)^+ --> D^*_s(2112)^+ pi^0 both in
inclusive e^+ e^- annihilation and in B decays. These two new states are
difficult to explain in terms of potential models.


title: Searches for Leptoquarks with the D-Zero Detector at the TeVatron

abstract:
  The existence of leptoquarks (LQ), color-triplets of bosons with lepton and
quark quantum numbers, is predicted by various theories beyond the Standard
Model. This article summarizes the D-Zero Run I searches for the three
different LQ generations in ppbar collisions at a center-of-mass energy of 1.8
TeV and presents ongoing studies at Run II.


title:
Measurement of the average time-integrated mixing probability of
  b-flavored hadrons produced at the Tevatron

abstract:
  We have measured the number of like-sign (LS) and opposite-sign (OS) lepton
pairs arising from double semileptonic decays of $b$ and $\bar{b}$-hadrons,
pair-produced at the Fermilab Tevatron collider. The data samples were
collected with the Collider Detector at Fermilab (CDF) during the 1992-1995
collider run by triggering on the existence of $\mu \mu$ and $e \mu$ candidates
in an event. The observed ratio of LS to OS dileptons leads to a measurement of
the average time-integrated mixing probability of all produced $b$-flavored
hadrons which decay weakly, $\bar{\chi} = 0.152 \pm 0.007$ (stat.) $\pm 0.011$
(syst.), that is significantly larger than the world average $\bar{\chi} =
0.118 \pm 0.005$.


title: W+W->Z+Z Scattering at the LHC

abstract:
  The process of vector boson scattering is of great interest because it is
completely prescribed in the Standard Model (SM) once the Higgs mass is known.
The LHC is a source of Z-Z pairs produced by means of the vector boson fusion
mechanism which is inferred by the presence of two additional forward (or tag)
jets. Because the reaction can be initiated by valence quarks and because the
W+W->Z+Z cross section approaches a constant in the SM, the scattering process
is accessible at the LHC.


title:
Observation of a narrow charmonium-like state in exclusive B+ -> K+
  pi+pi- J/psi decays

abstract:
  We report the observation of a narrow charmonium-like state produced in the
exclusive decay process B+ -> K+ pi+pi- J/psi. This state, which decays into
pi+pi- J/psi, has a mass of 3872.0+-0.6(stat)+-0.5(syst) MeV, a value that is
very near the M_D + M_D* mass threshold. The results are based on an analysis
of 152M B-Bbar events collected at the Upsilon(4S) resonance in the Belle
detector at the KEKB collider. The statistical significance of the signal is in
excess of 10 sigma.


title: b-production at the Tevatron

abstract:
  The phenomenology of b-production and some of the previous Run I measurements
of CDF and D0 are briefly reviewed. A new analysis by CDF of Run I b-bbar
angular correlations and a new measurement by D0 of Run II b-jet cross-section,
are presented.


title: Discovery Potential for SUGRA/SUSY at CMS

abstract:
  The expected SUSY discovery potential of the CMS experiment at LHC is
described, both in the MSSM and in the more constrained framework of mSugra,
with emphasis on inclusive searches, the MSSM Higgs sector, and one example of
complete reconstruction of a SUSY decay chain.


title: CP Violation, Mixing and Lifetime Results from BaBar

abstract:
  The BaBar collaboration has analysed 60M BB_ pairs collected at the Upsilon
(4S) resonance at the PEP II asymetric collider at SLAC. Using this data sample
we have measured the CP violation parameters sin (2beta)=0.75+/- 0.09 (STAT)
+/-0.04 (SYST) and lambda =0.92+/- 0.06 (STAT) +/- 0.02 (SYST) from B0 to
cc_+K*0 + c.c. decays. From charmless 2-body B decays we measure A_Kpi =-0.05
+/- 0.06 +/- 0.01(-0.14,+0.05), S_pipi = -0.01 +/- 0.37 +/- 0.07(-0.66,+0.62),
C_pipi =-0.02 +/- 0.29 +/- 0.07(-0.54,+0.48). A number of B lifetime and mixing
parameters, extracted from subsamples of this data set, are also presented.


title:
Experimental evidence for hadron deconfinement in p-p_bar collisions at
  centre-of-mass energy of 1.8 TeV in the FNAL C0 collider

abstract:
  We have measured deconfined hadronic volumes, 4.4 < V < 13.0 fm^3, produced
by one-dimensional(1D) expansion. The volumes are directly proportional to the
charged particle pseudorapidity densities 6.75 < dN_C/dn < 20.2. The
hadronization temperature is T = 179.5 +/- 5.0 (syst) MeV. The hadronization
energy density is epsilon = 1.10 +/- 0.26 GeV/fm^3, corresponding to an
excitation of 24.8 +/- 6.2 quark-gluon degrees of freedom.


title: Diffractive Final States and Tests of QCD Factorisation

abstract:
  Measurements of hard diffractive final states performed with the H1
experiment at HERA are presented and confronted with predictions based on
diffractive parton densities.


title: Search for the B Meson Decay to eta' phi

abstract:
  We present preliminary results of a search for the decay B0 -> eta' phi. The
data were recorded with the BaBar detector at the PEP-II asymmetric-energy
B-meson Factory at SLAC and correspond to 89 million B B-bar pairs produced in
e+e- annihilation at the Upsilon(4S) resonance. We find no evidence for a
signal and set a 90% CL upper limit of BF(B0 -> eta' phi) < 1.0 x 10^-6


title:
Measurement of sin2beta with Hadronic and Previously Unused Muonic J/psi
  Decays

abstract:
  We report a measurement of the CP-violation parameter sin2beta with B^0 ->
J/psi K^0_S decays in which the J/psi decays to hadrons or to muons that do not
satisfy our standard identification criteria. With a sample of 88 million BBbar
events collected by the BaBar detector at the PEP-II asymmetric-energy $B$
factory at SLAC, we reconstruct 100 +/- 17 such events, with J/psi -> pi^+ pi^-
pi^0 being the most prevalent, and measure sin2beta = 1.56 +/- 0.42 (stat.) +/-
0.21 (syst.).


title: An Analysis Of $\gamma p \to p \pi^+ \pi^-$ Using The CLAS Detector

abstract:
  Two charged pion final states are studied for GeV photons incident on
protons. The data come from Thomas Jefferson National Accelerator Facility
using the CLAS detector. A tagged photon beam of 0.5-2.4 GeV/c was produced
through bremsstrahlung radiation and was incident on a liquid H2 target. This
analysis looks at the reaction $\gamma p \to p \pi^+ \pi^-$ using a partial
wave analyis to identify intermediate baryon resonances. Total cross section is
compared to previous experiments and preliminary differential cross sections
for intermediate baryon resonance quantum numbers are shown.


title:
A Study of the Branching Ratio of H ->cc_bar at a Future e+e- Linear
  Collider

abstract:
  We carried out a feasibility study on the measurement of the branching ratio
of H -> cc_bar at a future e+e- linear collider. We used the topological vertex
reconstructing algorithm for accumulating secondary vertex information and the
neural network for optimizing c quark selection. With an assumption of a light
Higgs mass of 120 GeV/c^2, we estimated the statistical error of Br(H ->
cc_bar) to be 20.1% or 25.7% depending on the number of vertex detector layers
at the center-of-mass energy of 250 GeV and the intergrated luminosity of 500
fb^-1.


title:
Evidence for formation of a narrow pKshort resonance with mass near 1533
  MeV in neutrino interactions

abstract:
  A narrow baryon resonance is observed in invariant mass of the pKshort system
formed in neutrino and antineutrino collisions with nuclei. The mass of the
resonance is estimated as (1533+-5)MeV. The observed width is less than 20 MeV,
and is compatible with being entirely due to experimental resolution. The
statistical significance of the signal is near 6.7 standard deviations. As the
position of the observed resonance does not match the mass of any known
\Sigma^{*+} state, we believe that it arises from neutrino production of the
\Theta^+ pentaquark baryon. The analysis is based on the data obtained in past
neutrino experiments with big bubble chambers: WA21, WA25, WA59, E180 and E632.


title:
Charm dijet angular distributions in gamma-p collisions with ZEUS at
  HERA

abstract:
  Dijet angular distributions of photoproduction events in which a D*+/- meson
is produced in association with one of two energetic jets have been measured
using an integrated luminosity of 120 pb^1. The results are compared with
predictions from leading-order parton-shower Monte Carlo models and with
next-to-leading-order QCD calculations.


title: Charm hadronisation in gamma-p collisions with ZEUS at HERA

abstract:
  The measured D*+/-, D0, D+/-, D_s+/- and /\_c+/- photoproduction cross
sections have been used to determine charm fragmentation ratios and fractions
of c quarks hadronising as a particular charm hadron, f(c -> D, /\_c). Events
with a D*+/- meson produced in association with an energetic jet have been used
to measure the charm fragmentation function. The results are compared with
different models and with previous measurements.


title: Review of Two-Photon Interactions

abstract:
  Presented are recent results of two-photon interactions. Topics inlcude
photon structure functions, inclusive hadron production, differential cross
sections derived from tagged 2-photon fusion events and results in exclusive
hadron production, particularly the observations of the eta_c prime.


title: Inelastic photo- and electroproduction of charmonium

abstract:
  Measurements of inelastic production of charmonium with the ZEUS detector at
HERA are presented. J/\psi and psi' mesons have been identified using the decay
channel psi -> mu+ mu-.The data, corresponding to an integrated luminosity of
38 pb-1 in photoproduction and 73.3 pb-1 in electroproduction, are confronted
to theoretical predictions.


title: Probing the Standard Model with electroweak penguin B decays

abstract:
  Recent branching fraction and asymmetry results of Electroweak Penguin B
decays from BaBar, Belle and CLEO experiments are reviewed. While these
branching fractions are consistent with the Standard Model expectations and are
being used to extract heavy quark model parameters and CKM matrix elements, the
asymmetry results are just becoming sensitive to observe any new physics
effects.


title:
A study of short-time periodic variation of the B8 solar neutrino flux
  at Super-Kamiokande

abstract:
  Super-Kamiokande(SK) is a real-time detector capable of measuring the exact
time of solar neutrino events. This, combined with a relatively high yield of
these events of roughly 15 per day, allows a search for short-time variations
in the observed flux. Using all 1496 days of SK-I's solar data, we looked for
periodic variations of the observed solar neutrino flux, and found no
significant periodicity.


title: Rare B decays and direct CP violation at BABAR

abstract:
  The search for rare B decays and direct CP violation at BABAR is described.
The following measurements (based on integrated luminosities ranging from 56.4
to 81.9fb-1) are summarized: the inclusive branching fractions and direct CP
asymmetries of B+ to h+h-h+ (h=pi, K), the exclusive branching fractions of B+
to K+pi-pi+ (where significant signals are observed in the B+ to K*0(892)pi+,
B+ to f0(980)K+, B+ to chic0 K+, B+ to Dbar0 pi+ and B^+ to higher K*0 pi+
channels), the branching fractions of B+ to rho0rho+ and B+ to rho0 K*+, and
finally, the branching fractions, the longitudinal components, and the direct
CP asymmetries in B to phi K*.


title: Run II Diffractive Measurements at CDF

abstract:
  We present results on hard diffraction obtained by the CDF Collaboration in
Run II proton-antiproton collisions at the Fermilab Tevatron. Run I CDF results
on hard diffraction are also reviewed.


title:
Search for Kaluza-Klein Graviton Emission in $p\bar{p}$ Collisions at
  $\sqrt{s}=1.8$ TeV using the Missing Energy Signature

abstract:
  We report on a search for direct Kaluza-Klein graviton production in a data
sample of 84 ${pb}^{-1}$ of \ppb collisions at $\sqrt{s}$ = 1.8 TeV, recorded
by the Collider Detector at Fermilab. We investigate the final state of large
missing transverse energy and one or two high energy jets. We compare the data
with the predictions from a $3+1+n$-dimensional Kaluza-Klein scenario in which
gravity becomes strong at the TeV scale. At 95% confidence level (C.L.) for
$n$=2, 4, and 6 we exclude an effective Planck scale below 1.0, 0.77, and 0.71
TeV, respectively.


title: The proton structure function F2 with CLAS

abstract:
  Here we publish experimental data on the proton structure function F2
measured with CLAS detector during February and March 1999 in Thomas Jefferson
National Accelerator Facility (Virginia, USA).


title:
Tests of the Standard Model and Constraints on New Physics from
  Measurements of Fermion-Pair Production at 189-209 GeV at LEP

abstract:
  Cross-section and angular distributions for hadronic and lepton-pair final
states in e+e- collisions at centre-of-mass energies between 189 GeV and 209
GeV, measured with the OPAL detector at LEP, are presented and compared with
the predictions of the Standard Model. The measurements are used to determine
the electromagnetic coupling constant alphaem at LEP2 energies. In addition,
the results are used together with OPAL measurements at 91-183 GeV within the
S-matrix formalism to determine the gamma-Z interference term and to make an
almost model-independent measurement of the Z mass. Limits on extensions to the
Standard Model described by effective four-fermion contact interactions or the
addition of a heavy Z boson are also presented.


title: LHC Symposium 2003: Summary Talk

abstract:
  This summary talk reviews the LHC 2003 Symposium, focusing on expectations as
we prepare to leap over the current energy frontier into new territory. We may
learn from what happened in the two most recent examples of leaping into new
energy territory. Quite different scenarios appeared in those two cases. In
addition, we review the status of the machine and experiments as reported at
the Symposium. Finally, I suggest an attitude which may be most appropriate as
we look forward to the opportunities anticipated for the first data from the
LHC.


title:
Experimental study of the e^+e^-\to\pi^+\pi^-\pi^0 reaction by SND
  detector in the energy range sqrt{s}=0.42--1.38 GeV

abstract:
  The review of the SND results of the $e^+e^-\to\pi^+\pi^-\pi^0$ process study
in the energy range $\sqrt[]{s}=0.42$ -- 1.38 GeV at VEPP-2M collider, based on
about $2\times 10^6$ selected events, is presented. The total cross section,
parameters of the $\rho$, $\omega$, $\phi$ resonances, and $\omega^\prime$,
$\omega^{\prime\prime}$ states were obtained. It was found that $\rho\pi$ and
$\omega\pi^0$ intermediate states describe the reaction dynamics. The
experimental data cannot be described by a sum of only $\omega$, $\phi$,
$\omega^\prime$ and $\omega^{\prime\prime}$ resonances contributions. This can
be interpreted as a manifestation of the $\rho\to 3\pi$ decay, suppressed by
$G$-parity, with relative probability $B(\rho\to 3\pi) =
(1.01\pm^{0.54}_{0.36}\pm 0.034) \times 10^{-4}$.


title: Search for Charged Higgs Bosons at LEP

abstract:
  A search for pair-produced charged Higgs bosons is performed with the L3
detector at LEP using data collected at centre-of-mass energies between 189 and
209GeV, corresponding to an integrated luminosity of 629.4/pb. Decays into a
charm and a strange quark or into a tau lepton and its neutrino are considered.
No significant excess is observed and lower limits on the mass of the charged
Higgs boson are derived at the 95% confidence level. They vary from 76.5 to
82.7GeV, as a function of the H->tv branching ratio.


title:
Measurement of Inclusive f_1(1285) and f_1(1420) Production in Z Decays
  with the DELPHI Detector

abstract:
  DELPHI results are presented on the inclusive production of two (K Kbar pi)^0
states in the mass region 1.2-1.6 GeV/c^2 in hadronic Z decays at LEP I. The
measured masses (widths) are 1274 +/- 6 MeV/c^2 (29 +/- 12 MeV/c^2) and 1426
+/- 6 MeV/c^2 (51 +/- 14 MeV/c^2) respectively. A partial-wave analysis of the
(K Kbar pi)^0 system shows that the first peak is consistent with the
I^G(J^{PC})=0^+(1^{++})/(0^{-+}) a_0(980)pi and the second with the
I^G(J^{PC})=0^+(1^{++}) K^*(892)Kbar + c.c. assignments. The total hadronic
production rates per hadronic Z decay are (0.165 +/- 0.051) and (0.056 +/-
0.012) respectively. These measurements are consistent with the two states
being the f_1(1285) and f_1(1420) mesons.


title:
First measurement of the double-inclusive B/Bbar hadron energy
  distribution in e+e- annihilations, and of angle-dependent moments of the B
  and Bbar energies

abstract:
  We have made the first measurement of the double-inclusive B/Bbar energy
distribution in e+e- annihilations, using a sample of 400,000 hadronic Z0 decay
events recorded in the SLD experiment at SLAC between 1996 and 1998. The small
and stable SLC beam spot and the CCD-based vertex detector were used to
reconstruct B/Bbar decay vertices with high efficiency and purity, and to
provide measurements of the kinematic quantities used to calculate the B
energies in this novel technique. We measured the B/Bbar energies with good
efficiency and resolution over the full kinematic range. We measured moments of
the scaled energies of the B and Bbar hadrons vs. the opening angle between
them. By comparing these results with perturbative QCD predictions we tested
the ansatz of factorisation in heavy-quark production. A recent next-to-leading
order calculation reproduces the data.


title: Rare hadronic B decays: probing deeper into the Standard Model

abstract:
  We present recent results from the Belle experiment on rare hadronic B meson
decays. The results are based on a 78 fb^{-1} data sample and consist of
branching fractions, CP asymmetries, and polarization amplitudes. The decays
studied include two-body pseudoscalar-pseudoscalar final states (B -> pi pi, K
pi, KK, and D^0 K^\pm); pseudoscalar-vector final states (B -> omega pi, omega
K, and phi K); and vector-vector final states (B -> phi K* and rho^+ rho^0).


title: Search for B^- --> J/psi Lambda p-bar decay

abstract:
  We report the results of a search for $B^{-} \to \jpsi \Lambda \pbar$ based
on a data set of 78 fb$^{-1}$ data collected at the $\Upsilon(4S)$ resonance
with the Belle detector at the KEKB asymmetric $e^+ e^-$ collider. No
substantial signal is found, and we set the branching fraction upper limit
${\cal B}(B^{-} \to \jpsi \Lambda \pbar) < 4.1 \times 10^{-5}$ at 90%
confidence level.


title: Studies of QCD at LEPII

abstract:
  A combination of measurements of alpha_s in e+e- annihilation at LEP is
presented. Distributions of various event-shape variables measured by ALEPH,
DELPHI, L3 and OPAL at centre-of-mass energies from 41 GeV to 206 GeV are
analysed in a common theoretical framework using O(a_s**2)+NLLA predictions.
The dominant theoretical uncertainties associated to missing higher orders are
studied in detail.


title: QCD at e+e- Experiments

abstract:
  A summary of QCD results obtained at e+e- experiments in recent years is
given. Emphasis is put on basic QCD tests and \alpha_s measurements with event
shapes.


title: Studying QCD in the Final State of High Energy Collisions

abstract:
  I give an outline and some discussion of the results presented during the
hadronic final states parallel sessions of the meeting, and some opinions about
the current state of play and future directions in this area.


title: New CKM-related studies on b decays in the DELPHI experiment at LEP

abstract:
  The e-e+ collider LEP, running at sqrt{s} = m(Z0), has been a copious source
of b-hadrons produced in decays Z0 -> b \b. We present recent studies using up
to 4*10^6 hadronic Z0 decays acquired by the DELPHI detector between 1992 and
2000. They rely on efficient particle identification, precise track and vertex
reconstruction and sophisticated data analysis algorithms.
  Presented are: a new measurement of the CKM matrix element |V_cb| in the
semileptonic exclusive decays B0_d -> D*+ l- \nu_l; a new measurement of the
B0_d - \B0_d oscillation frequency Delta(m_d); and searches by three methods
for B0_s - \B0_s oscillations, yielding new lower limits on Delta(m_s).


title: Cabibbo-Suppressed Decays of D^+ \to \pi^+\pi^0, K^+\bar{K}^0, K^+\pi^0

abstract:
  Using a 13.7 fb-1 data sample collected with the CLEO II and II.V detectors,
we report new branching fraction measurements for two Cabibbo-suppressed decay
modes of the D+ meson: BR(D+ -> pi+ pi0) = (1.31 +/- 0.17 +/- 0.09 +/- 0.09) x
10^(-3)and BR(D+ -> K+ K0bar) = (5.24 +/- 0.43 +/- 0.20 +/- 0.34) x 10^(-3)
which are significant improvements over past measurements. The errors reflect
statistical and systematical uncertainties as well as the uncertainty in the
absolute D+ branching fraction scale. We also set the first 90% confidence
level upper limit on the branching fraction of the doubly Cabibbo-suppressed
decay mode BR(D+ -> K+ pi0) < 4.2 x 10^(-4).


title: W physics at LEP

abstract:
  Studying the properties of the W boson plays a key role in precision tests of
the Standard Model. The key measurements performed over the last decade will be
reviewed. W-pair and single-W cross-sections and W decay branching fractions
are determined and agree well with theoretical predictions. Including the
analysis of differential distributions, trilinear and quartic couplings of the
W boson to the other gauge bosons are extracted. A precise measurement of the
mass and width of the W boson is presented. The W mass is in good agreement
with the one obtained indirectly from an analysis of other electroweak data
measured at LEP and SLD. Some of the results presented in this article are
preliminary.


title:
Physics potential of the decays Bs;d -> J/psi eta and Bs -> J/psi phi in
  the ATLAS experiment at the LHC

abstract:
  The CP asymmetry predicted by the Standard Model in the decay modes Bs;d ->
J/psi eta and Bs -> J/psi phi is very small, and the observation of a sizeable
e ect would be a clear indication of new physics beyond the Standard Model.
Contrary to the final state J/psi phi, the former final state is a CP
eigenstate, and therefore complex angular distribution analyses are not
necessary for the asymmetry measurement. In this paper, the approaches for the
study of these two decay channels are presented.


title:
Search for Single Top Production in ep Collisions at HERA using the H1
  Detector

abstract:
  In this talk a search for the single production of top quarks performed at
the H1 experiment is presented. No evidence for anomalous top production via
FCNC processes is found and limits on the anomalous magnetic coupling constant
\kappa_{tu\gamma} are given.


title: Search for B^0 -> l^+ l^- at Belle

abstract:
  We report the results of a search for the decay B^0 -> e^+ e^-, mu^+ mu^- and
e^{+-} mu^{-+} based on an analysis of 78 fb^{-1} of data collected by the
Belle detector at KEKB. No candidate events have been found. Upper limits on
the branching fractions are calculated at the 90% confidence level: B(B^0 ->
e^+ e^-) < 1.9 x 10^{-7}, B(B^0 -> mu^+ mu^-) < 1.6 x 10^{-7}, and B(B^0 ->
e^{+-} mu^{-+})< 1.7 x 10^{-7}. A limit on the Pati-Salam leptoquark mass
M_{LQ}> 46 TeV/c^2 is obtained at the 90% confidence level.


title: Jet physics in e+e- annihilation from 14 to 209 GeV

abstract:
  Results from the study of jets in hadronic final states produced in e+e-
annihilation at sqrt(s)=14 to 209 GeV are discussed. Precise measurements of
the strong coupling alpha_S at many points of sqrt(s) provide convincing
evidence for the running of alpha_S as expected by QCD. Several measurements of
the running b-quark mass m_b(M_Z) are combined yielding
m_b(M_Z)=(2.92+-0.03(stat.)+-0.31(syst.)) GeV and compared with low energy
results. Strong evidence for the running of the b-quark mass is found.
Experimental investigations of the gauge structure of QCD are reviewed and then
combined with the results for the colour factors C_A=2.89+-0.01(stat.)+-
0.21(syst.) and C_F=1.30+-0.01(stat.)+-0.09(syst.) and correlation coefficient
rho=0.82. The uncertainties on the colour factors are below 10% and the
agreement with the QCD expectation C_A=3 and C_F=4/3 is excellent.


title:
Phase Motion in the Scalar Low-Mass $\pi^-\pi^+$ Amplitude in $D^+ \to
  \pi^-\pi^+\pi^+$

abstract:
  This work is a direct and model-independent measurement of the low mass
$\pi^+\pi^-$ phase motion in the $D^+ \to \pi^-\pi^+\pi^+$ decay. The results
show a strong phase variation, compatible with an isoscalar $\sigma(500)$
meson. This result confirms the previous Fermilab E791 result which found
evidence for the existence of this scalar particle using a full Dalitz-plot
analysis.


title: Search for the Rare Decay KL --> pi0 ee

abstract:
  The KTeV/E799 experiment at Fermilab has searched for the rare kaon decay
KL--> pi0ee. This mode is expected to have a significant CP violating
component. The measurement of its branching ratio could support the Standard
Model or could indicate the existence of new physics. This letter reports new
results from the 1999-2000 data set. One event is observed with an expected
background at 0.99 +/- 0.35 events. We set a limit on the branching ratio of
3.5 x 10^(-10) at the 90% confidence level. Combining the results with the
dataset taken in 1997 yields the final KTeV result: BR(KL --> pi0 ee) < 2.8 x
10^(-10) at 90% CL.


title: Recent Results of psi(2S) Decays at BES

abstract:
  Using 14 million psi(2S) data sample collected with BES at BEPC, psi(2S)->
VT, K_long K_short(also J/psi -> K_long K_short), and chi_cJ -> Baryon
anti-Baryon decays are measured and compared with theoretical model
predications.


title: Hadronic B Decays with BaBar

abstract:
  We report about the studies of the decay channels B- -> D0 K-, B0 -> D*- a1+
and B0 -> Ds(*)- pi+ with a sample of 62.10^6 Upsilon(4S) decays into B meson
pairs collected with the BaBar detector at the PEP II asymmetric e+ e-
collider.


title: Observation of the rare decay Ks->pi0e+e-

abstract:
  A search for the decay Ks->pi0e+e- has been made by the NA48/1 experiment at
the CERN SPS accelerator. Using data collected during 89 days in 2002 with a
high-intensity Ks beam, 7 events were found with a background of 0.15 events.
The branching fraction BR(Ks->pi0e+e-, m(ee) > 0.165 GeV/c^2) =
(3.0^{+1.5}_{-1.2}(stat) +/-0.2 (syst)) x 10^{-9} has been measured. Using a
vector matrix element and a form factor equal to one, the measurement gives
BR(Ks->pi0e+e-) = (5.8^{+2.9}_{-2.4}) x 10^{-9}.


title: Search for Doubly-Charged Higgs Bosons at LEP

abstract:
  Doubly-charged Higgs bosons are searched for in e^+e^- collision data
collected with the L3 detector at LEP at centre-of-mass energies up to 209 GeV.
Final states with four leptons are analysed to tag the pair-production of
doubly charged Higgs bosons. No significant excess is found and lower limits at
95% confidence level on the doubly-charged Higgs boson mass are derived. They
vary from 95.5 GeV to 100.2 GeV, depending on the decay mode. Doubly-charged
Higgs bosons which couple to electrons would modify the cross section and
forward-backward asymmetry of the e^+e^- -> e^+e^- process. The measurements of
these quantities do not deviate from the Standard Model expectations and
doubly-charged Higgs bosons with masses up to the order of a TeV are excluded.


title:
Measurement of K^+K^- production in two-photon collisions in the
  resonant-mass region

abstract:
  K^+K^- production in two-photon collisions has been studied using a large
data sample of 67 fb^{-1} accumulated with the Belle detector at the KEKB
asymmetric e^+e^- collider. We have measured the cross section for the process
gamma gamma -> K^+ K^- for center-of-mass energies between 1.4 and 2.4 GeV, and
found three new resonant structures in the energy region between 1.6 and 2.4
GeV. The angular differential cross sections have also been measured.


title: New Results in Kaon Physics from NA48 and KTEV

abstract:
  In the recent year many new results from kaon decays have been reported from
both the NA48 experiment at CERN and the KTeV experiment at Fermilab. Both
experiments have new and improved measurements of the parameter
Re(epsilon'/epsilon) of direct CP violation in the neutral kaon system. Also
several new results on rare and very rare K_L decays were reported. In
addition, the NA48 collaboration has performed special high-intensity K_S run
periods, with the first results now being available.


title:
Proof of principle for a high sensitivity search for the electric dipole
  moment of the electron using the metastable a(1)[^3\Sigma^+] state of PbO

abstract:
  The metastable a(1)[^3\Sigma^+] state of PbO has been suggested as a suitable
system in which to search for the electric dipole moment (EDM) of the electron.
We report here the development of experimental techniques allowing
high-sensitivity measurements of Zeeman and Stark effects in this system,
similar to those required for an EDM search. We observe Zeeman quantum beats in
fluorescence from a vapor cell, with shot-noise limited extraction of the
quantum beat frequencies, high counting rates, and long coherence times. We
argue that improvement in sensitvity to the electron EDM by at least two orders
of magnitude appears possible using these techniques.


title:
Study of the e^+e^-\to\pi^0\gamma process in the energy range 0.60-1.06
  GeV

abstract:
  The process e^+e^-\to\pi^0\gamma in the energy range \sqrt{s}=0.60-1.06 GeV
was studied at VEPP-2M collider with SND detector using 14 pb^{-1} of
integrated luminosity. Data were analyzed in the framework of the vector meson
dominance model. Preliminary results on obtained cross-section and parameters
of \rho^0, \omega ,\phi \to \pi^0\gamma radiative decays are presented.


title: KsKs resonances in deep inelastic scattering at HERA

abstract:
  Inclusive KsKs production in deep inelastic ep scattering at HERA has been
studied with the ZEUS detector using an integrated luminosity of 120 pb-1. Two
states are observed at masses of 1537{+9}{-8} MeV and 1726{+-7} MeV, as well as
an enhancement around 1300 MeV. The state at 1537 MeV is consistent with the
well established f'2(1525). The state at 1726 MeV may be the glueball candidate
f0(1710). However, it's width of 38{+20}{-14} MeV is narrower than 125{+-10}
MeV observed by previous experiments for the f0(1710).


title: Q^2 Evolution of the Neutron Spin Structure Moments using a He-3 Target

abstract:
  We have measured the spin structure functions $g_1$ and $g_2$ of $^3$He in a
double-spin experiment by inclusively scattering polarized electrons at
energies ranging from 0.862 to 5.07 GeV off a polarized $^3$He target at a
15.5$^{\circ}$ scattering angle. Excitation energies covered the resonance and
the onset of the deep inelastic regions. We have determined for the first time
the $Q^2$ evolution of $\Gamma_1(Q^2)=\int_0^{1} g_1(x,Q^2) dx$,
$\Gamma_2(Q^2)=\int_0^1 g_2(x,Q^2) dx$ and $d_2 (Q^2) = \int_0^1 x^2[
2g_1(x,Q^2) + 3g_2(x,Q^2)] dx$ for the neutron in the range 0.1 GeV$^2$ $\leq
Q^2 \leq $ 0.9 GeV$^2$ with good precision. $ \Gamma_1(Q^2)$ displays a smooth
variation from high to low $Q^2$. The Burkhardt-Cottingham sum rule holds
within uncertainties and $d_2$ is non-zero over the measured range.


title: Triple Vector Boson Production at the LHC

abstract:
  The interaction among vector bosons is crucial to understanding electroweak
symmetry breaking. At the LHC one technique is to use "tag" jets to identify
vector boson fusion processes leading to two vector bosons and two "tag" jets
in the final state. Another approach is to study the production of three vector
bosons in the final state. There is a clear tradeoff since in the latter case
clear "tags" are not available, although the cross sections are substantially
larger than those for vector boson fusion.


title: The Detector and Interaction Region for a Photon Collider at TESLA

abstract:
  TESLA is designed as an electron-positron linear collider (LC) based on
super-conducting technology. A second interaction region is forseen to be
incorporated in the design allowing its possible operation as a photon
collider. In this paper I describe the basic design of the $\gamma \gamma$
interaction region taking into account the beam-beam and laser related issuses
and review some aspects of other accelerator components such as the feedback
system and the beam dump which are critical to the operation of TESLA as a
photon collider.


title:
Charge Conjugation and Parity Violations as a Signature for Black Hole
  Formation or Other New Physics in Hadron Collisions

abstract:
  I point out that there have been essentially no tests of discrete symmetries,
such as baryon number, charge conjugation (C), parity (P), strangeness,
isospin, etc., in high energy, high pT hadron collisions. If, for example,
black hole formation (BHF) occurs, we might expect large violations of C, P,
>... I propose new tests of C and P that can be adapted to a variety of new
physics scenarios by selecting events with appropriate topologies. Large
effects, such as ~10% longitudinal polarizations of outgoing particles, might
be expected in events involving BHF. These tests may provide more sensitive
searches for new physics at existing colliders.


title: Search for Scalar Leptons and Scalar Quarks at LEP

abstract:
  Scalar partners of quarks and leptons, predicted in supersymmetric models,
are searched for in e^+e^- collisions at centre-of-mass energies between 192GeV
and 209GeV at LEP. No evidence for any such particle is found in a data sample
of 450 pb^-1. Upper limits on their production cross sections are set and lower
limits on their masses are derived in the framework of the Minimal
Supersymmetric Standard Model.


title: Deep inelastic diffractive scattering at HERA

abstract:
  Recent high precision measurements of deep inelastic diffractive scattering
at HERA are presented in an increased region of phase space. Current models for
diffractive photon dissociation are compared to the data.


title:
A study of the nuclear medium influence on transverse momentum of
  hadrons produced in deep inelastic neutrino scattering

abstract:
  The influence of nuclear effects on the transverse momentum $(p_T)$
distributions of neutrinoproduced hadrons is investigated using the data
obtained with SKAT propane-freon bubble chamber irradiated in the neutrino beam
(with $E_{\nu}$ = 3-30 GeV) at Serpukhov accelerator. Dependences of $<p_T^2>$
on the kinematical variables of inclusive deep-inelastic scattering and of the
produced hadrons are measured. It has been observed, that the nuclear effects
cause an enhancement of $<p_T^2>$ of hadrons (more pronounced for the
positively charged ones) produced in the target fragmentation region at low
invariant mass of the hadronic system (2 $< W <$ 4 GeV) or at low energies
transferred to the current quark (2 $< \nu < 9$ GeV). At higher $W$ or $\nu$,
no influence of nuclear effects on $<p_T^2>$ is observed. Measurement results
are compared with predictions of a simple model, incorporating secondary
intranuclear interactions of hadrons (with a formation length extracted from
the Lund fragmentation model), which qualitatively reproduces the main features
of the data.


title: Hard Processes in Electron-Proton Scattering

abstract:
  This report summarizes some of the recent HERA results obtained by studying
hard processes in ep-scattering. By resolving the structure of the proton, hard
ep-reactions provide information on the parton content of the proton and may
give insight into the dynamics of the exchanged parton cascade. In addition,
their study offers the possibility to test the Standard Model, in particular
perturbative Quantum Chromodynamics, on which the theoretical predictions on
ep-scattering cross sections are generally based. Any observed deviation
between the data and existing theoretical models would either indicate the need
to calculate higher order contributions or hint at signs of new physics.


title: New Analysis Strategy to Search for New Particles at LHC

abstract:
  The ATLAS and CMS experiments at LHC have great physics potential in
discovering many possible new particles, from Standard Model (SM) Higgs boson
to supersymmetric (SUSY) and other beyond the SM new particles over a very
large mass range around the TeV scale. We first review the current analysis
strategy in searching for new particles at LHC and its vulnerability to
statistical fluctuations. We then discuss an alternative new analysis strategy
in order to avoid this vulnerability. We use maximum likelihood method as an
example and discuss the new challenges in using maximum likelihood method as
such a new analysis strategy to search for new particles at LHC.

Study of the Process e+ e- --> pi0 pi0 gamma in c.m. Energy Range
  600--970 MeV at CMD-2

abstract:
  The cross section of the process e+ e- --> pi0 pi0 gamma has been measured in
the c.m. energy range 600--970 MeV with the CMD-2 detector. The following
branching ratios have been determined: B(rho --> pi0 pi0 gamma)
=(5.2^{+1.5}_{-1.3} +- 0.6)x10^{-5} and B(omega --> pi0 pi0 gamma)
=(6.4^{+2.4}_{-2.0} +- 0.8)x10^{-5}. Evidence for the rho --> f0(600) gamma
decay has been obtained: B(rho --> f0(600) gamma) = (6.0^{+3.3}_{-2.7}\pm
0.9)x10^{-5}. From a search for the process e+ e- --> eta pi0 gamma the
following upper limit has been obtained: B(omega --> eta pi0 gamma) < 3.3
10^{-5} at 90% CL.


title:
Study of Z Pair Production and Anomalous Couplings in e+e- Collisions at
  sqrt(s) between 190 GeV and 209 GeV

abstract:
  A study of Z-boson pair production in e+e- annihilation at center-of-mass
energies between 190 GeV and 209 GeV is reported. Final states containing only
leptons, (l+l-l+l- and l+l-nn), quark and lepton pairs, (qql+l-, qqnn) and only
hadrons (qqqq) are considered. In all states with at least one Z boson decaying
hadronically, lifetime, lepton and event-shape tags are used to separate bb
pairs from qq final state. Limits on anomalous ZZgamma and ZZZ couplings are
derived from the measured cross sections and from event kinematics using an
optimal observable method. Limits on low scale gravity with large dimensions
are derived from the cross sections and their dependence on polar angle.


title:
Observation of an Exotic S = -2, Q = -2 Baryon Resonance in
  Proton-Proton Collisions at the CERN SPS

abstract:
  Results of resonance searches in the Xi- pi-, Xi- pi+, antiXi+ pi- and
antiXi+ pi+ invariant mass spectra in proton-proton collisions at sqrt{s}=17.2
GeV are presented. Evidence is shown for the existence of a narrow Xi- pi-
baryon resonance with mass of 1.862+/-0.002 GeV/c^2 and width below the
detector resolution of about 0.018 GeV/c^2. The significance is estimated to be
4.0 sigma. This state is a candidate for the hypothetical exotic Xi_(3/2)^--
baryon with S = -2, I = 3/2 and a quark content of (d s d s ubar). At the same
mass a peak is observed in the Xi- pi+ spectrum which is a candidate for the
Xi_(3/2)^0 member of this isospin quartet with a quark content of (d s u s
dbar). The corresponding antibaryon spectra also show enhancements at the same
invariant mass.


title: Measurement of the Branching Fraction for B+- --> chi_c0 K+-

abstract:
  We present a measurement of the branching fraction of the decay B+- -->
chi_c0 K+- from a sample of 89 million BB pairs collected by the BaBar detector
at the PEP-II asymmetric-energy B Factory at SLAC. The chi_c0 meson is
reconstructed through its two-body decays to pi+ pi- and K+ K-. We measure
BR(B+- --> chi_c0 K+-)* BR(chi_c0 --> pi+ pi-) = (1.32^{+0.28}_{-0.27}(stat) +-
0.09(syst))*10^-6 and BR(B+- --> chi_c0 K+-) * BR(chi_c0 --> K+ K-) =
(1.49^{+0.36}_{-0.34}(stat) +- 0.11(syst))* 10^-6. Using the known values for
the chi_c0 decays branching fractions, we combine these results to obtain
BR(B+- --> chi_c0 K+-) = (2.7+-0.7)* 10^-4.


title: Diffractive Final States with the H1 Detector at HERA

abstract:
  Recent measurements of diffractive dijet and charm quark production in
electron-proton collisions using the H1 detector at HERA are presented, where
the exchanged photon is either almost real or highly virtual. The data are
compared with leading and next-to-leading order QCD calculations based on the
diffractive parton distributions obtained from a recent DGLAP QCD analysis of
H1 inclusive diffractive deep-inelastic scattering data, thus testing QCD
factorization in diffractive ep interactions.


title:
Production of pi+, pi-, K+, K-, p and p-bar in Light (uds), c and b Jets
  from Z0 Decays

abstract:
  We present improved measurements of the differential production rates of
stable charged particles in hadronic Z0 decays, and of charged pions, kaons and
protons identified over a wide momentum range using the SLD Cherenkov Ring
Imaging Detector. In addition to flavor-inclusive Z0 decays, measurements are
made for Z0 decays into light (u, d, s), c and b primary flavors, selected
using the upgraded Vertex Detector. Large differences between the flavors are
observed that are qualitatively consistent with expectations based upon
previously measured production and decay properties of heavy hadrons. These
results are used to test the predictions of QCD in the Modified Leading
Logarithm Approximation, with the ansatz of Local Parton-Hadron Duality, and
the predictions of three models of the hadronization process. The light-flavor
results provide improved tests of these predictions, as they do not include the
contribution of heavy-hadron production and decay; the heavy-flavor results
provide complementary model tests. In addition we have compared hadron and
antihadron production in light quark (as opposed to antiquark) jets.
Differences are observed at high momentum for all three charged hadron species,
providing direct probes of leading particle effects, and stringent constraints
on models.


title: Observation of B+ -> p pbar pi+, B0 -> p pbar K0, and B+ -> p pbar K*+

abstract:
  We report the first observation of a b -> u type charmless baryonic B decay,
B+ -> p pbar pi+, as well as b -> s type B0 -> p pbar K0 and B+ -> p pbar K*+
decays. The analysis is based on a 78fb^{-1} data sample recorded on the
Upsilon(4S) resonance with the Belle detector at KEKB. We find BF(B+ -> p pbar
pi+) = (3.06^{+0.73}_{-0.62} \pm 0.37)*10^{-6}, BF(B0 -> p pbar K0)
=(1.88^{+0.77}_{-0.60} \pm 0.23)*10^{-6}, and BF(B+ -> p pbar K*+) =
(10.3^{+3.6 + 1.3}_{-2.8 -1.7})*10^{-6}. We also update BF(B+ -> p pbar K+) =
(5.66^{+0.67}_{-0.57} \pm 0.62)* 10^{-6}, and present an upper limit on BF(B0
-> p pbar K*0) at the 90% confidence level. A common feature of the observed
decay modes is threshold peaking in baryon pair invariant mass.


title: Inclusive Dijet Production at Low Bjorken-x in Deep Inelastic Scattering

abstract:
  Dijet production in deep inelastic ep scattering is investigated in the
region of low values of the Bjorken-variable x (10^-4 < x < 10^-2) and low
photon virtualities Q^2 (5 < Q^2 < 100 GeV^2). The measured dijet cross
sections are compared with perturbative QCD calculations in next-to-leading
order. For most dijet variables studied, these calculations can provide a
reasonable description of the data over the full phase space region covered,
including the region of very low x. However, large discrepancies are observed
for events with small separation in azimuth between the two highest transverse
momentum jets. This region of phase space is described better by predictions
based on the CCFM evolution equation, which incorporates k_t factorized
unintegrated parton distributions. A reasonable description is also obtained
using the Color Dipole Model or models incorporating virtual photon structure.


title: Search for Extra Dimensions at LHC

abstract:
  Some of the studies performed by the ATLAS and CMS collaborations to
establish the future sensitivity of the experiments to extra dimension signals
are reviewed. The discrimination of those signals from other new physics
signals and the extraction of the underlying parameters of the extra dimension
models are discussed.


title: The CLEO-c Research Program

abstract:
  In spring 2003, the B physics era ended for the CLEO experiment with a final
run at the Y(5S) resonance. Over the summer the experiment and the CESR
accelerator were modified to operate at lower center-of-mass energies between 3
and 5 GeV. In September 2003 the CLEO-c detector has begun to take its first
data at the psi(3770) resonance, with which a new era for the exploration of
the charmonium sector begins. The CLEO-c research program presented here will
include studies of leptonic, semileptonic and hadronic charm decays, searches
for exotic, gluonic matter and test for new physics beyond the Standard Model.


title: Lifetime measurement of atoms consisting of pi+ and pi- mesons

abstract:
  The lifetime measurement of pi+pi- atoms (A2pi) with 10% precision provides
in a model independent way the difference between the S-wave pion-pion
scattering lengths for isospin 0 and 2, |a0 -a2|, with 5% accuracy. The
scattering lengths a0 and a2 have been calculated in Chiral Perturbation Theory
(ChPT) with a precision better than 2.5%. Therefore, such a measurement will be
a sensitive check of the understanding of chiral symmetry breaking in QCD by
giving an indication about the value of the quark condensate, an order
parameter of QCD. The method of observation and lifetime measurement of A2pi
are discussed. Data on A2pi production in Pt, Ni and Ti targets and preliminary
results for the lifetime measurement are presented.


title: Improved measurement of the branching ratio of J/psi-->K_S K_L

abstract:
  The branching ratio of J/psi-->K_S K_L is measured with improved precision to
be B(J/psi-->K_S K_L) = (1.82\pm 0.04\pm 0.13)\times 10^{-4}. using J/psi data
collected with the Beijing Spectrometer (BESII) at the Beijing
Electron-Positron Collider. This result is used to test the perturbative QCD
``12%'' rule between psi(2S) and J/psi decays and to investigate the relative
phase between the three-gluon and one-photon annihilation amplitudes in J/psi
decays.


title: First observation of psi(2S)-->K_S K_L

abstract:
  The decay psi(2S)-->K_S K_L is observed for the first time using psi(2S) data
collected with the Beijing Spectrometer (BESII) at the Beijing Electron
Positron Collider (BEPC); the branching ratio is determined to be
B(psi(2S)-->K_S K_L) = (5.24\pm 0.47 \pm 0.48)\times 10^{-5}. Compared with
J/psi-->K_S K_L, the psi(2S) branching ratio is enhanced relative to the
prediction of the perturbative QCD ``12%'' rule. The result, together with the
branching ratios of psi(2S) decays to other pseudoscalar meson pairs
(\pi^+\pi^- and K^+K^-), is used to investigate the relative phase between the
three-gluon and the one-photon annihilation amplitudes of psi(2S) decays.


title: Heavy Ion Collisions

abstract:
  Lattice QCD predicts a phase transition between hadronic matter and a system
of deconfined quarks and gluons (the Quark Gluon Plasma) at high energy
densities. Recent results from the Brookhaven Relativistic Heavy Ion Collider
(RHIC) dedicated to the study of QCD at extreme densities will be discussed and
compared to measurements obtained at the CERN Super Proton Synchrotron (SPS).


title: Recent Charm from CLEO

abstract:
  We present some recent results in rare charm decays from CLEO Collaboration.
The data used were collected by the CLEO II and III detectors at the Cornell
Electron Storage Ring (CESR). A brief future outlook for the CESR-c/CLEO-c
program is also presented.


title:
J/psi production via initial state radiation in e+ e- --> mu+ mu- gamma
  at an e+e- center-of-mass energy near 10.6 GeV

abstract:
  We have used a study of the process e+e- --> mu+ mu- gamma at a
center-of-mass energy near the Y(4S) resonance for a mu+ mu- invariant mass
range near the J/psi mass to extract the cross section sigma(e+e- --> J/psi
gamma --> mu+ mu- gamma). The data set, corresponding to an integrated
luminosity of 88.4 fb-1, was collected using the BaBar detector at the PEP-II
collider. We measure the product Gamma(J/psi --> e+e-)B(J/psi --> mu+ mu-) to
be 0.330 +/- 0.008(stat) +/- 0.007(syst) keV. Using the world averages for
B(J/psi --> mu+ mu-) and B(J/psi --> e+e-), we derive the J/psi electronic and
total widths: Gamma(J/psi --> e+e-)=5.61+/-0.20 keV and Gamma=94.7+/-4.4 keV.


title:
Measurement of Branching Fractions of Color-Suppressed Decays of the
  B0bar Meson to D(*)0 pi0, D(*)0 eta, D(*)0 omega, and D0 eta_prime

abstract:
  Using a sample of 88.8 10**6 BBbar events collected with the BaBar detector
at the PEP-II storage rings at the Stanford Linear Accelerator Center, we
measure the branching fractions of seven color-suppressed B-meson decays:
  BF(B0bar to D0 pi0)=(2.9 +/- 0.2(stat.)+/- 0.3(syst.))*10**-4,
  BF(B0bar to D*0 pi0)=(2.9 +/- 0.4(stat.)+/- 0.5(syst.))*10**-4,
  BF(B0bar to D0 eta)=(2.5 +/- 0.2(stat.)+/- 0.3(syst.))*10**-4,
  BF(B0bar to D*0 eta)=(2.6 +/- 0.4(stat.)+/- 0.4(syst.))*10**-4,
  BF(B0bar to D0 omega)=(3.0 +/- 0.3(stat.)+/- 0.4(syst.))*10**-4,
  BF(B0bar to D*0 omega)=(4.2 +/- 0.7(stat.)+/- 0.9(syst.))*10**-4, and
BF(B0bar to D0 eta_prime)=(1.7 +/- 0.4(stat.)+/- 0.2(syst.))*10**-4.
  We set the 90 % confidence-level upper limit:
  BF(B0bar to D*0 eta_prime) < 2.6*10**-4.
  The channels B0bar to D*0 eta, D*0 omega, and D0 eta_prime are seen with more
than five-sigma statistical significance. All of these branching fractions are
significantly larger than theoretical expectations based on the ``naive''
factorization model.


title: An Upper Bound on the Decay tau -> mu gamma from Belle

abstract:
  We have performed a search for the lepton-flavor-violating decay tau -> mu
gamma using a data sample of 86.3fb^{-1} accumulated by the Belle detector at
KEK. No evidence for a signal is seen, and we set an upper limit for the
branching fraction of B(tau -> mu gamma) < 3.1 x 10^{-7} at the 90% confidence
level.


title:
Constraints on Nucleon Decay via "Invisible" Modes from the Sudbury
  Neutrino Observatory

abstract:
  Data from the Sudbury Neutrino Observatory have been used to constrain the
lifetime for nucleon decay to ``invisible'' modes, such as n -> 3 nu. The
analysis was based on a search for gamma-rays from the de-excitation of the
residual nucleus that would result from the disappearance of either a proton or
neutron from O16. A limit of tau_inv > 2 x 10^{29} years is obtained at 90%
confidence for either neutron or proton decay modes. This is about an order of
magnitude more stringent than previous constraints on invisible proton decay
modes and 400 times more stringent than similar neutron modes.


title: Scalar mesons and delta0-delta2 at KLOE

abstract:
  The KLOE measurement of phi radiative decays and of the ratio
Gamma(Ks->pi+pi-(gamma))/Gamma(Ks->pi0pi0) are discussed. The first measurement
aims at understanding the real nature of the scalar mesons a0 and f0, whose
possible compositions are qq, qqqq, or KK molecule. The second measurement is
related to the estimate of the phase shift difference delta0-delta2. Previous
measurements were affected by a large uncertainty due to the presence of
radiative effects which are correctly included in our analysis.


title: Search for Single Top Quark Production in ep Collisions at HERA

abstract:
  A search for single top quark production is performed in e^\pm p collisions
at HERA. The search exploits data corresponding to an integrated luminosity of
118.3 pb^-1. A model for the anomalous production of top quarks in a flavour
changing neutral current process involving a t-u-gamma coupling is
investigated. Decays of top quarks into a b quark and a W boson are considered
in the leptonic and the hadronic decay channels of the W. Both a cut-based
analysis and a multivariate likelihood analysis are performed to discriminate
anomalous top quark production from Standard Model background processes. In the
leptonic channel, 5 events are found while 1.31 \pm 0.22 events are expected
from the Standard Model background. In the hadronic channel, no excess above
the expectation for Standard Model processes is found. These observations lead
to a cross section \sigma (ep -> e t X) = 0.29 +0.15 -0.14 pb at \sqrt{s} = 319
GeV. Alternatively, assuming that the observed events are due to a statistical
fluctuation, upper limits of 0.55 pb on the anomalous top production cross
section and of 0.27 on the t-u-gamma coupling \kappa_{t-u-gamma} are
established at the 95% confidence level.


title: Search for Extra Dimensions at Hadron Colliders

abstract:
  To explain the large difference between the Planck scale and the electroweak
scale, models in which gravity propagates in more than four dimensions have
recently been proposed. In this paper, results from searches for extra
dimensions at the Tevatron ppbar collider are presented. Limits are set on the
higher dimensional Planck scale, and expectations for the LHC pp collider are
given.


title: Black Holes at Future Colliders and in Cosmic Rays

abstract:
  One of the most dramatic consequences of low-scale (~1 TeV) quantum gravity
would be copious production of mini black holes at future accelerators and in
ultra-high-energy cosmic ray interactions. Hawking radiation of these black
holes is constrained mainly to our (3+1)-dimensional world and results in their
rapid evaporation. We review selected topics in the mini-black-hole
phenomenology, such as production rates at colliders and in cosmic rays,
Hawking radiation as a sensitive probe of the dimensionality of extra space, as
well as an exciting possibility of finding new physics in the decays of black
holes.


title: Distributed Computing Concepts in D0

abstract:
  The D0 experiment faces many challenges enabling access to large datasets for
physicists on four continents. The new concepts for distributed large scale
computing implemented in D0 aim for an optimal use of the available computing
resources while minimising the person-power needed for operation. The real live
test of these concepts is of special interest for the LHC Computing GRID, LCG,
which follows a similar strategy.


title: Recent BES charmonium results

abstract:
  Using 58 million $J/\psi$ decays, we have investigated the $p \bar{p}$
invariant mass spectrum in the radiative decay $J/\psi \to \gamma p \bar{p}$
and observe a prominent structure with mass near $2m_p$. Fitting with an S-wave
Breit-Wigner, we obtain a peak mass of $M= 1859^{+3}_{-10}(\rm
stat)^{+5}_{-25}(sys) MeV/c^2$. $J/\psi \to \gamma \eta_c$ decays from the same
sample are used to determine the mass, width, and hadronic branching ratios of
the $\eta_c$. From a sample of 14 million $\psi(2S)$ events, the first
observation of $\chi_{cJ}$ (J=0,1,2) decays to $\Lambda\bar{\Lambda}$ is made,
and branching ratios are determined, which are larger than expected from the
Color Octet Model. Branching ratios of $K_s^0K_L^0$ in both $\psi(2S)$ and
$J/\psi$ decays are measured, and a more than four sigma deviation from the
pQCD predicted "12% rule" is observed. In $\psi(3770)$ decays, evidence for the
non-$D\bar{D}$ decay to $\pi^+\pi^-J/\psi$ is observed.


title:
Measurement of Time-Dependent CP Asymmetries and Constraints on
  sin(2beta+gamma) with Partial Reconstruction of B0 -> D*-+ pi+- Decays

abstract:
  We present a measurement of time-dependent CP-violating asymmetries in decays
of neutral B mesons to the final states D*-+ pi+-, using approximately 82
million B B bar events recorded by the BABAR experiment at the PEP-II e+ e-
storage ring. Events containing these decays are selected with a partial
reconstruction technique, in which only the high-momentum pi+- from the B decay
and the low-momentum pi-+ from the D*-+ decay are used. We measure the
amplitude of the asymmetry to be -0.063 +- 0.024(stat.) +- 0.014(syst.) and
compute bounds on |sin(2beta + gamma)|.


title: Multiplicities and particle production at LEP

abstract:
  Recent results on hadron multiplicities in heavy and light quark
fragmentation above the Z peak (OPAL), and multiplicity distribution analysis
(L3) and inclusive f_1 production (DELPHI) in hadronic Z decays are presented.


title: Latest News from SNO

abstract:
  A summary of the intial pure D2O phase results is presented in the first half
of the paper. The second half describes the various aspects of the calibration
and detector reponse analysis carried out for the second `salt' phase of
running. In addition, estimates on the precision attainable with the salt data
are presented.


title: Recent b-physics results from OPAL

abstract:
  The most recent b-physics results from the OPAL experiment at LEP are
reviewed. A measurement of semileptonic B meson decays to narrow
orbitally-excited charm mesons is presented first, followed by a study of charm
production in b-hadron decays. Here, B refers to B+ and B0 mesons and their
charge conjugates, and b-hadron refers to the admixture of hadrons containing a
b quark produced in electron-positron annihilations at \sqrt{s}= m_Z.


title:
On the narrow dip structure at 1.9 GeV/c$^2$ in diffractive
  photoproduction

abstract:
  The narrow dip observed at 1.9 GeV/c$^2$ by the Fermilab experiment E687 in
diffractive photoproduction of $~3\pi^+3\pi^-$ is examined. The E687 data are
refitted, a mechanism is proposed to explain why this resonance appears as a
dip, and possible interpretations are discussed.


title: Study on Neutron-induced Background in the CRESST Experiment

abstract:
  CRESST II is an experiment for direct WIMP search, using cryogenic detectors.
The ratio of the two signals (temperature rise and scintillation light)
measured for each interaction is an excellent parameter for discrimination of
radioactive background. The main remaining background is the neutron flux
present at the experimental site, since neutrons produce the same signals as
WIMPs do. Based on Monte Carlo simulations the present work shows how neutrons
from different origins affect CRESST and which measures have to be taken into
account to reach the goal sensitivity.


title: Measurement of the Mass Difference m(D_s^+) - m(D^+) at CDF II

abstract:
  We present a measurement of the mass difference m(D+_s) - m(D+), where both
the D+_s and D+ are reconstructed in the phi pi+ decay channel. This
measurement uses 11.6 pb-1 of data collected by CDF II using the new
displaced-track trigger. The mass difference is found to be: 99.41 +- 0.38
(stat) +- 0.21 (syst) MeV/c^2.


title: Charm Physics at CDF II

abstract:
  The CDF II detector has the capability of triggering on displaced tracks.
Because of this ability, CDF II has accrued large samples of charmed meson
decays to fully hadronic final states in 64 pb^-1 of ppbar collision data
gathered at sqrt(s) = 1.96 TeV. Using initial Run II data samples, the
production cross sections for J/psi, D0, D+, D*+ and Ds+ mesons have been
measured. Ratios of branching ratios for Cabibbo suppressed final states and CP
asymmetries in D0 meson decays have been studied. A measurement of the mass
difference m(Ds+) - m(D+) has been done, and a limit for the branching fraction
of the FCNC D0 -> mu+ mu- decays has been set.


title:
HERA Transverse Polarimeter absolute scale and error by rise-time
  calibration

abstract:
  We give the results of an analysis of some 18 rise-time calibrations which
are based on data collected in 1996/97. Such measurements are used to determine
the absolute polarization scale of the transverse electron beam polarimeter
(TPOL) at HERA. The results of the 1996/97 calibrations are found to be in good
agreement with earlier calibrations of the TPOL performed in 1994 with errors
of 1.2% and 1.1%. Based on these calibrations and a comparison with
measurements from the longitudinal polarimeter (LPOL) at HERA carried out over
a two-months period in 2000, we obtain a mean LPOL/TPOL ratio of 1.018. Both
polarimeters are found to agree with each other within their overall errors of
about 2% each.


title: TESLA Polarimeters

abstract:
  We describe a study of high-energy Compton beam polarimeters for the future
e+e- linear collider machine TESLA. A segment of the beam delivery system has
been identified, which is aligned with the e+e- collision axis and which has a
suitable configuration for high-quality beam polarization measurements. The
laser envisaged for the polarimeter is similar to an existing facility at DESY.
It delivers very short pulses in the 10 ps, 10-100uJ regime and operates with a
pattern that matches the pulse and bunch structure of TESLA. This will permit
very fast and accurate measurements and an expeditious tune-up of the spin
manipulators at the low-energy end of the linac. Electron detection in the
multi-event regime will be the principle operating mode of the polarimeter.
Other possible operating modes include photon detection and single-event
detection for calibration purposes. We expect an overall precision of dP/P=0.5%
for the measurement of the beam polarization.


title:
A High Sensitivity Search for $\bar{\nu}_{e}$'s from the Sun and Other
  Sources at KamLAND

abstract:
  Data corresponding to a KamLAND detector exposure of 0.28 kton-year has been
used to search for $\bar{\nu}_e$'s in the energy range 8.3 MeV $<$
E$_{\bar{\nu}_e}$ $<$ 14.8 MeV. No candidates were found for an expected
background of $1.1{\pm}0.4$ events. This result can be used to obtain a limit
on $\bar{\nu}_{e}$ fluxes of any origin. Assuming that all $\bar{\nu}_e$ flux
has its origin in the Sun and has the characteristic $^8$B solar $\nu_e$ energy
spectrum, we obtain an upper limit of 3.7 \times 10$^2$ cm$^{-2}$ s$^{-1}$ (90%
C.L.) on the $\bar{\nu}_e$ flux. We interpret this limit, corresponding to
$2.8{\times}10^{-4}$ of the Standard Solar Model $^8$B $\nu_e$ flux, in the
framework of spin--flavor precession and neutrino decay models.


title:
Experimental studies of unbiased gluon jets from e+e- annihilations
  using the jet boost algorithm

abstract:
  We present the first experimental results based on the jet boost algorithm, a
technique to select unbiased samples of gluon jets in e+e- annihilations, i.e.
gluon jets free of biases introduced by event selection or jet finding
criteria. Our results are derived from hadronic Z0 decays observed with the
OPAL detector at the LEP e+e- collider at CERN. First, we test the boost
algorithm through studies with Herwig Monte Carlo events and find that it
provides accurate measurements of the charged particle multiplicity
distributions of unbiased gluon jets for jet energies larger than about 5 GeV,
and of the jet particle energy spectra (fragmentation functions) for jet
energies larger than about 14 GeV. Second, we apply the boost algorithm to our
data to derive unbiased measurements of the gluon jet multiplicity distribution
for energies between about 5 and 18 GeV, and of the gluon jet fragmentation
function at 14 and 18 GeV. In conjunction with our earlier results at 40 GeV,
we then test QCD calculations for the energy evolution of the distributions,
specifically the mean and first two non-trivial normalized factorial moments of
the multiplicity distribution, and the fragmentation function. The theoretical
results are found to be in global agreement with the data, although the
factorial moments are not well described for jet energies below about 14 GeV.


title: Doubly Charmed Baryons in COMPASS

abstract:
  The search for doubly charmed baryons has been a topic for COMPASS from the
beginning. Requiring however a complete spectrometer and highest possible
trigger rates this measurement has been postponed. The scenario for such a
measurement in the second phase of COMPASS is outlined here. First studies of
triggering and simulation of the setup have been performed. New rate estimates
based on recent measurements from SELEX at FNAL are presented.


title:
Observation of a Narrow Meson Decaying to Ds pi0 gamma at a Mass of
  2.458 GeV/c^2

abstract:
  A narrow state, which we label DsJ(2458)+, with mass 2458.0 +/- 1.0(stat.)
+/- 1.0(syst.) MeV/c^2, is observed in the inclusive Ds+ pi0 \gamma$ mass
distribution in 91 fb-1 of e^+e^- annihilation data recorded by the BABAR
detector at the PEP-II asymmetric-energy e^+e^- storage ring. The observed
width is consistent with the experimental resolution. The data favor decay
through Ds*(2112)+ pi0 rather than through DsJ*(2317)+ gamma. An analysis of
Ds+ pi0 data accounting for the influence of the DsJ(2458)+ produces a
DsJ*(2317)+ mass of 2317.3 +/- 0.4(stat.) +/- 0.8(syst.) MeV/c^2.


title: Study of Hadronic Five-Body Decays of Charmed Mesons Involving $K_S^0$

abstract:
  We study the decay of $D^0$ and $D^+_s$ mesons into five-body final states
including a $K_S^0$ and report the discovery of the decay mode $D_s^+\to K_S^0
K_S^0\pi^+\pi^+\pi^-$. The branching ratio for the new mode is
{${\Gamma(D_s^+\to K_S^0K_S^0\pi^+\pi^-\pi^+)} \over {\Gamma(D_s^+\to
K_S^0K^-\pi^+\pi^+)}$} = 0.102$\pm0.029\pm$0.029.
  We also determine the branching ratio of {${\Gamma(D^0\to
K_S^0\pi^+\pi^+\pi^-\pi^-)} \over {\Gamma(D^0 \to K_S^0\pi^+\pi^-)}$} =
0.095$\pm0.005\pm$0.007 as well as an upper limit for {${\Gamma(D^0\to
K_S^0K^-\pi^+\pi^+\pi^-)} \over {\Gamma(D^0\to K_S^0\pi^+\pi^+\pi^-\pi^-)}$}
$<$ 0.054 (90% CL). An analysis of the resonant substructure for $D^0 \to
K_S^0\pi^+\pi^+\pi^-\pi^-$ is also performed.

Determination of the strange form factors of the nucleon from $\nu p$,
  $\bar{\nu} p$, and parity-violating $\vec{e}p$ elastic scattering

abstract:
  A new method of obtaining the strange form factors of the nucleon is
presented, in which forward-angle parity-violating $\vec{e}p$ elastic
scattering data is combined with $\nu p$ and $\bar{\nu} p$ elastic scattering
data. The axial form factor in electron-nucleon scattering is complicated by
the presence of electro-weak radiative corrections that in principle need to be
calculated or separately measured, but this axial form factor is suppressed at
forward angles. The neutrino data has no such complication. Hence the use of
forward-angle parity-violating $\vec{e}p$ data with $\nu p$ and $\bar{\nu} p$
data allows the extraction of all three strange form factors: electric,
magnetic and axial ($G_E^s$, $G_M^s$, and $G_A^s$). In this letter, $\nu p$ and
$\bar{\nu} p$ data from the Brookhaven E734 experiment are combined with the
Jefferson Lab HAPPEX $\vec{e}p$ data to obtain two distinct solutions for the
strange form factors at $Q^2$ = 0.5 GeV$^2$. More generally, combining the
neutrino elastic scattering data from E734 with the existing and upcoming
$\vec{e}p$ data will yield the strange form factors of the nucleon for $Q^2$ of
0.45-1.05 GeV$^2$. Measurement of $G_A^s$ is crucial to the determination of
the strange quark contribution to the nucleon spin, $\Delta s$.

title: Search for R-Parity Violating Decays of Scalar Fermions at LEP

abstract:
  A search for pair-produced scalar fermions under the assumption that R-parity
is not conserved has been performed using data collected with the OPAL detector
at LEP. The data samples analysed correspond to an integrated luminosity of
about 610 pb-1 collected at centre-of-mass energies of sqrt(s) 189-209 GeV. An
important consequence of R-parity violation is that the lightest supersymmetric
particle is expected to be unstable. Searches of R-parity violating decays of
charged sleptons, sneutrinos and squarks have been performed under the
assumptions that the lightest supersymmetric particle decays promptly and that
only one of the R-parity violating couplings is dominant for each of the decay
modes considered. Such processes would yield final states consisting of
leptons, jets, or both with or without missing energy. No significant
single-like excess of events has been observed with respect to the Standard
Model expectations. Limits on the production cross- section of scalar fermions
in R-parity violating scenarios are obtained. Constraints on the supersymmetric
particle masses are also presented in an R-parity violating framework analogous
to the Constrained Minimal Supersymmetric Standard Model.


title: Measurements of Jet and Multijet Cross Sections with the CDF Detector

abstract:
  Recent measurements of jet and multijet production cross sections from ppbar
collisions recorded with the Collider Detector at Fermilab (CDF) are
summarized. First Run II results of the inclusive one jet cross section at
sqrt(s) = 1.96 TeV as well as prospects for future extensions of this
measurement are presented. We also studied the properties of three-jet events
in Run Ib data at sqrt(s) = 1.8 TeV. All results are compared to predictions of
Quantum Chromodynamics at next-to-leading order perturbation theory.


title: The BTeV Experiment

abstract:
  BTeV is an approved forward collider experiment at the Fermilab Tevatron
dedicated to precision studies of CP violation, mixing, and rare decays of
beauty and charmed hadrons. The BTeV detector has been designed to achieve
these goals. Pixel detectors cover the interaction region and vertex
computation is included in the lowest level trigger.


title: Top and Electroweak Physics from the Tevatron

abstract:
  With the advent of the Tevatron Run 2, the collider experiments, CDF and D0,
have reestablished the top quark and the W and Z signals and have begun
programs of precision measurements of top quark and electroweak properties. We
will survey some of the first Run 2 results from these analyses, and when
appropriate compare with the Run 1 results. Finally we will give the status of
Higgs boson searches and prospects at the Tevatron.


title:
Cross Sections and Transverse Single-Spin Asymmetries in Forward
  Neutral-Pion Production from Proton Collisions at \sqrt{s} = 200 GeV

abstract:
  Measurements of the production of forward high-energy pi0 mesons from
transversely polarized proton collisions at \sqrt{s}=200 GeV are reported. The
cross section is generally consistent with next-to-leading order perturbative
QCD calculations. The analyzing power is small at x_F below about 0.3, and
becomes positive and large at higher x_F, similar to the trend in data at
\sqrt{s}<=20 GeV. The analyzing power is in qualitative agreement with
perturbative QCD model expectations. This is the first significant spin result
seen for particles produced with p_T>1 GeV/c at a polarized proton collider.


title: Beta-Beams: present design and expected performances

abstract:
  We give the present status of the beta-beam study, which aims at producing
intense nue and antinue beams from the decay of relativistic radioactive io ns.
The emphasis is put on recent technical progress and new ideas. The expected
performances in terms of neutrino mixing parameters theta13 and CP violating
phase delta using a megaton water Cerenkov detector installed in the Frejus
underground laboratory are shown to be excellent, and the synergy with a a
companion SuperBeam is underlined.


title: Search for $\pi^0 \to \nu_{\mu}\bar\nu_{\mu}$ Decay in LSND

abstract:
  We observe a net beam-excess of $8.7 \pm 6.3$ (stat) $\pm 2.4$ (syst) events,
above 160 MeV, resulting from the charged-current reaction of $\nu_{\mu}$
and/or $\bar\nu_{\mu}$ on C and H in the LSND detector. No beam related muon
background is expected in this energy regime. Within an analysis framework of
$\pi^0 \to \nu_{\mu}\bar\nu_{\mu}$, we set a direct upper limit for this
branching ratio of $\Gamma(\pi^0 \to \nu_\mu \bar\nu_\mu) / \Gamma(\pi^0 \to
all) < 1.6 \times 10^{-6}$ at 90% confidence level.


title: Spectroscopy and Charm Quark Fragmentation

abstract:
  The large data sample accumulated at the KEKB storage ring allows for
dedicated analysis in charm spectroscopy. This made the first observations of
e.g. the broad D**resonances in B decays as well as other processes possible.
The observation of the DsJ resonances are confirmed and indications of their
quantum numbers are given. The fragmentation function for D*+ has been measured
with unprecedented accuracy.


title: Electroweak Penguin B Decays at Belle

abstract:
  We summarise the most recent results of the Belle experiment about flavour
changing neutral current (FCNC) radiative and (semi-) leptonic B decays. In
particular, we report about the first observation of the decays B->K*l+l-,
B->phi K gamma, the inclusive B->Xs l+l-$. We also report about searches for
B->l+l- decay and for CP asymmetries in B->K*gamma.


title: Measurements of Event and Jet Shapes at HERA

abstract:
  Event shapes and jet shapes in neutral current deep inelastic scattering and
photoproduction are studied with the H1 and ZEUS detectors at HERA. The
measurements are compared to next-to-leading-order QCD calculations and Monte
Carlo models. The strong coupling constant is determined from subjet
multiplicities.


title: The Solar Neutrino Day/Night Effect in Super-Kamiokande

abstract:
  The time variation of the elastic scattering rate of solar neutrinos with
electrons in Super-Kamiokande-I was fit to the day/night variations expected
from active two-neutrino oscillations in the Large Mixing Angle region.
Combining Super-Kamiokande measurements with other solar and reactor neutrino
data, the mixing angle is determined as sin^2theta=0.276+0.033-0.026 and the
mass squared difference between the two neutrino mass eigenstates as Delta
m^2=7.1+0.6-0.5x10^-5eV^2. For the best fit parameters, a day/night asymmetry
of -1.7+-1.6(stat)+1.3-1.2(syst)% was determined from the Super-Kamiokande
data, which has improved statistical precision over previous measurements and
is in excellent agreement with the expected value of -1.6%.


title:
Low Energy Neutrino Physics at the Kuo-Sheng Reactor Neutrino Laboratory
  in Taiwan

abstract:
  A laboratory has been constructed by the TEXONO Collaboration at the
Kuo-Sheng Reactor Power Plant in Taiwan to study low energy neutrino physics.
The facilities of the laboratory are described. A limit on the neutrino
magnetic moment of $\rm{\munuebar < 1.3 \times 10^{-10} ~ \mub}$ at 90%
confidence level has been achieved from measurements with a high-purity
germanium detector. Other physics topics, as well as the various R&D program,
are surveyed.


title: The eta_c(2980) formation in two-photon collisions at LEP energies

abstract:
  eta_c(2980) production in gamma-gamma interactions has been detected via its
decays into K0_s K+/- pi-/+, K+ K- K+ K- and K+ K- pi+ pi- in the data taken
with the DELPHI detector at LEP1 and LEP2 energies. The two-photon radiative
width averaged over all observed decay channels is \Gamma_{\gamma\gamma} = 13.9
+/- 2.0 (stat.) +/- 1.4 (syst.) +/- 2.7 (BR) keV. No direct decay channel eta_c
-> pi+ pi- pi+ pi- has been observed. An upper limit $\Gamma_{\gamma\gamma}$ <
5.5 keV at 95% confidence level has been evaluated for this decay mode.


title: b-tagging in DELPHI at LEP

abstract:
  The standard method used for tagging b-hadrons in the DELPHI experiment at
the CERN LEP Collider is discussed in detail. The main ingredient of b-tagging
is the impact parameters of tracks, which relies mostly on the vertex detector.
Additional information, such as the mass of particles associated to a secondary
vertex, significantly improves the selection efficiency and the background
suppression. The paper describes various discriminating variables used for the
tagging and the procedure of their combination. In addition, applications of
b-tagging to some physics analyses, which depend crucially on the performance
and reliability of b-tagging, are described briefly.


title:
Measurement of the e+e- -> W+W-gamma Cross-section and Limits on
  Anomalous Quartic Gauge Couplings with DELPHI

abstract:
  W+W-gamma production at LEP2 is studied using data collected with the DELPHI
detector at centre-of-mass energies between 189 GeV and 209 GeV, corresponding
to an integrated luminosity of about 600 pb^-1. Cross-sections are measured for
the production of W+W- with a hard, central and isolated photon in the final
state, and are found to be compatible with the Standard Model prediction. The
photon energy spectra are used to derive limits on anomalous contributions to
the W+W-Z0gamma and W+W-gammagamma vertices.


title:
A measurement of the branching fractions of the b-quark into charged and
  neutral b-hadrons

abstract:
  The production fractions of charged and neutral b-hadrons in b-quark events
from Z0 decays have been measured with the DELPHI detector at LEP. An algorithm
has been developed, based on a neural network, to estimate the charge of the
weakly-decaying b-hadron by distinguishing its decay products from particles
produced at the primary vertex. From the data taken in the years 1994 and 1995,
the fraction of bbar-quarks fragmenting into positively charged weakly-decaying
b-hadrons has been measured to be: f^+ = (42.09 +/- 0.82 (stat.) +/- 0.89
(syst.))%. Subtracting the rates for charged Xibar_b^+ and Omegabar_b^+ baryons
gives the production fraction of B^+ mesons: f_Bu = (40.99 +/- 0.82 (stat.) +/-
1.11 (syst.))%.


title: Latest Results from Dafne

abstract:
  The Dafne Frascati phi factory has continously improved its performances
reaching in 2002 an instantaneous luminosity of 8x10^31 cm-2 s-1. The DEAR
experiment, concluded in 2002, has measured the de-excitation of kaonic atoms.
The KLOE experiment, still running, has measured several branching ratios for
neutral and charged kaons decays, rho, eta, eta', a0 and f0 mesons parameters
and, via the radiative return, the e+e- -> pi+pi- cross section. Preliminary
and final results are presented.


title: Recent Results from KamLAND

abstract:
  The Kamioka Liquid-scintillator Anti-Neutrino Detector (KamLAND) has detected
for the first time the disappearance of electron antineutrinos from a
terrestrial source at the 99.95% C.L. Interpreted in terms of neutrino
oscillations, the best fit to the KamLAND data gives a mixing angle 1.0 and a
mass-squared difference 6.9 x 10^-5 eV^2, in excellent agreement with the Large
Mixing Angle solution to the solar neutrino problem. Assuming CPT invariance,
this result excludes other solutions to the solar neutrino problem at > 99.95%
C.L.


title: Measurement of the Average $\phi$ Multiplicity in $B$ Meson Decay

abstract:
  We present a measurement of the average multiplicity of $\phi$ mesons in
$B^0$, $\kern 0.18em\bar{\kern -0.18em B}{}^0$ and $B^\pm$ meson decays. Using
$17.6 fb^{-1}$ of data taken at the $\Upsilon{(4S)}\xspace$ resonance by the
{\slshape B\kern-0.1em{\smaller A}\kern-0.1em B\kern-0.1em{\smaller
A\kern-0.2em R}} detector at the PEP-II $e^+e^-\xspace$ storage ring at the
Stanford Linear Accelerator Center, we reconstruct $\phi$ mesons in the
$K^+K^-$ decay mode and measure ${\cal{B}}(B\to \phi X) =
(3.41\pm0.06\pm0.12)%$. This is significantly more precise than any previous
measurement.


title: Transverse Momentum Fluctuations in Nuclear Collisions at 158 AGeV

abstract:
  Results are presented on event-by-event fluctuations in transverse momentum
of charged particles, produced at forward rapidities in p+p, C+C, Si+Si and
Pb+Pb collisions at 158 AGeV. Three different characteristics are discussed:
the average transverse momentum of the event, the Phi_pT fluctuation measure
and two-particle transverse momentum correlations. In the kinematic region
explored, the dynamical fluctuations are found to be small. However, a
significant system size dependence of Phi_pT is observed, with the largest
value measured in peripheral Pb+Pb interactions. The data are compared with
predictions of several models.
