Measurement of the b quark forward-backward asymmetry around the Z0 peak
  using an inclusive tag

abstract:
  The b quark forward-backward asymmetry has been measured using hadronic Z0
decays collected by the OPAL experiment at LEP. Z0 -> bbbar decays were
selected using a combination of secondary vertex and lepton tags, and the sign
of the b quark charge was determined using an inclusive tag based on jet,
vertex and kaon charges. The results, corrected to the quark level, are:
  A^b_FB = 0.0582 +- 0.0153 +- 0.0012 at sqrt(s) = 89.50 GeV A^b_FB = 0.0977 +-
0.0036 +- 0.0018 at sqrt(s) = 91.26 GeV A^b_FB = 0.1221 +- 0.0123 +- 0.0025 at
sqrt(s) = 92.91 GeV where the first error is statistical and the second
systematic in each case. Within the framework of the Standard Model, the result
is interpreted as a measurement of the effective weak mixing angle for
electrons of sin2theta_W^eff,e = 0.23205 +- 0.00068.


title: W Boson Cross Section and Decay Properties at the Tevatron

abstract:
  We present the first measurements of sigma(p\bar{p} -> W -> l nu) and
sigma(p\bar{p} -> Z -> l l) at sqrt{s} = 1.96 TeV, along with new measurements
of W angular-decay distributions in p\bar{p} collisions at sqrt{s} = 1.8 TeV.


title: Search for the Standard Model Higgs Boson with the OPAL Detector at LEP

abstract:
  This paper summarises the search for the Standard Model Higgs boson in e+e-
collisions at centre-of-mass energies up to 209 GeV performed by the OPAL
Collaboration at LEP. The consistency of the data with the background
hypothesis and various Higgs boson mass hypotheses is examined. No indication
of a signal is found in the data and a lower bound of 112.7GeV/C^2 is obtained
on the mass of the Standard Model Higgs boson at the 95% CL.


title: Multiplicities, fluctuations and correlations

abstract:
  The recent results on hadron multiplicities in heavy and light quark
fragmentation, multiplicity local fluctuations and multiparticle correlations
submitted to the Conference are reviewed.


title: Psi(2S) two- and three-body hadronic decays

abstract:
  We report measurements of branching fractions for psi(2S) decays into omega
pi pi, b1 pi,omega f2(1270),omega KK, omega p pbar, phi pi pi, phi f0(980),phi
KK, and an upper limit for phi p pbar final states based on a data sample of 4
X 10^6 psi(2S) events collected with the BESI detector at the Beijing
Electron-Positron Collider. The branching fractions for b1 pi and omega
f2(1270) update previous BES results, while those for other decay modes are
first measurements. The ratios of psi(2S)and J/psi branching fractions are
smaller than what is expected from the 12% rule by a factor of five for omega
f2(1270),by a factor of two for omega pi pi, omega p pbar, and phi KK, while
for other studied channels the ratios are consistent with expectation within
errors.


title: Deeply Virtual Compton Scattering at HERA

abstract:
  Deeply virtual Compton scattering has recently been studied by three HERA
experiments, H1, ZEUS and HERMES, covering a broad range of kinematic regimes.
We present cross section measurements of the two collider experiments in the
kinematic region 2<Q^2<100 GeV^2 and 30<W<140 GeV, and compare them to
QCD-based calculations. HERMES measurements of azimuthal asymmetries and their
kinematical dependences are presented for Q^2>1 GeV^2 and 2<W<7 GeV.


title: The CERN-Gran Sasso Neutrino Program

abstract:
  This paper reviews the current experimental program envisaged with the future
CERN neutrino beam called CNGS. Two detectors, OPERA and ICARUS, are under
preparation and should investigate the neutrino properties coming from the CNGS
to shed light on neutrino oscillation physics.


title: KTeV Results: Re($\epsilon' / \epsilon$) and Rare Decay Results

abstract:
  The KTeV physics program encompasses many goals including a precision
measurement of the direct CP violation parameter Re($\epsilon' / \epsilon$) in
$K \to \pi \pi$ decays, and studies of rare neutral kaon decays. The KTeV
detector collected data during the Fermilab fixed-targed runs of 1996-97 and
1999. This article focuses on the precision measurement of the direct CP
violation parameter Re($\epsilon' / \epsilon$) using the 1996-97 data set. In
addition, measurements of the neutral kaon parameters $\tau_S$, $\Delta m$,
$\phi_{+-}$, $\Delta \phi$ from that data set and a new measurement of the
branching fraction of $K_L \to e^+ e^- \mu^+ \mu^-$ from the 1997 and 1999 data
also are presented.


title: Searches for gauge mediated SUSY breaking at LEP

abstract:
  The four LEP collaborations have performed searches for supersymmetric
particles in light gravitino scenarios, when neutralinos and sleptons are
produced and may present measurable decay lengths. The highest energy data has
been analysed including centre-of-mass energies up to 209 GeV. No evidence for
such particles is found, but preliminary limits from the combination allow to
exclude at 95% confidence level neutralino masses up to 97 GeV if neutralinos
decay promptly and stau masses up to 86.9 GeV for all stau lifetimes. The
interpretation of these results in general models is studied to set limits on
the parameters of the theory.


title: The D0 Detector for Run II

abstract:
  The general purpose D0 collider detector at the Fermilab Tevatron has
undergone major upgrades for Run II. We describe the current status and
performance of the D0 detector.


title: Electroweak Physics

abstract:
  The status of precision electroweak measurements as of summer 2002 is
reviewed. The recent results on the anomalous magnetic moment of the muon and
on neutrino-nucleon scattering are discussed. Precision results on the
electroweak interaction obtained by the experiments at the SLC, LEP and
TEVATRON colliders are presented. The experimental results are compared with
the predictions of the minimal Standard Model and are used to constrain its
parameters, including the mass of the Higgs boson. The final LEP results on the
direct search for the Higgs boson of the Standard Model are presented.


title:
On the possibility of measuring the gluon distribution in proton with
  "photon+jet" events at LHC

abstract:
  The number of events suitable for a determination of the gluon distribution
function g(x,Q^2) in a proton at the LHC for various intervals of x and Q^2 are
estimated. The contributions of main background sources to ``direct
photon+jet'' production processes are studied. The values of discrimination
powers between quark and gluon jets as well as between a single photon and the
products of pi^0, eta, K^0_s mesons decaying through the neutral channels are
applied to estimate the final contributions of various event types to the
"photon+jet" production in different intervals of x and Q^2. Monte Carlo events
generated by help of the PYTHIA 6.1 generator are used for this analysis.


title:
Letter of Intent to build an Off-axis Detector to study numu to nue
  oscillations with the NuMI Neutrino Beam

abstract:
  The NuMI neutrino beam line and the MINOS experiment represent a major
investment of US High Energy Physics in the area of neutrino physics. The
forthcoming results could decisively establish neutrino oscillations as the
underlying physics mechanism for the atmospheric $\numu$ deficit and provide a
precise measurement of the corresponding oscillation parameters, $\dmsq23$ and
$\sinsq2t23$.neutrino sector may well be within our reach. The full potential
of the NuMI neutrino beam can be exploited by complementing the MINOS detector,
under construction, with a new detector(s) placed at some off-axis position and
collecting data in parallel with MINOS. The first phase of the proposed program
includes a new detector, optimized for $\nue$ detection, with a fiducial mass
of the order of 20 kton and exposed to neutrino and antineutrino beams. In a
five year run its sensitivity to the $\numutonue$ oscillations will be at least
a factor of ten beyond the current limit.
  The future direction of the program will depend on the results of this first
phase, but it is very likely that it will be a combination of a significant
increase of the neutrino beam intensity via an upgraded proton source and an
increase of the detector mass by a factor of five or so. Depending on the
circumstances, the goals of Phase II may be a further increase of the
sensitivity of a search for $\numutonue$ oscillations, or, perhaps, a
measurement of the CP violating phase $\delta$ in the lepton sector.


title:
Neutrino Physics and Astrophysics with the MACRO Experiment at the Gran
  Sasso Lab

abstract:
  The results of the MACRO experiment on atmospheric neutrino oscillations are
presented and discussed. The data concern different event topologies with
average neutrino energies of ~ 4 and ~ 50 GeV. The Multiple Coulomb Scattering
of muons in the MACRO absorbers was used to estimate the neutrino energy of
each event of the higher energy sample. The angular distributions, the absolute
fluxes and the L/E distribution favour nu_mu <--> nu_tau oscillations with
maximal mixing and Delta m^2=0.0025 eV^2. Results are presented on the searches
for astrophysical sources of high energy muon neutrinos, for bursts of electron
antineutrinos from stellar gravitational collapses and on indirect searches for
WIMPs from the Earth and from the Sun.


title: Neutrinoless Double Beta Decay: Present and Future

abstract:
  Present status, and future plans for Double Beta Decay searches are reviewed.
Given the recent observations of neutrino oscillations, a possibility to
observe $\beta\beta(0\nu)$~ at a neutrino mass scale suggested by present
experimental results ($m_{\nu} \approx$10-50 meV) could actually exist. The
achievement of the required experimental sensitivity is a real challenge faced
by a series of new proposed projects. Plans to achieve such a result are
described.


title: Atmospheric neutrino oscillations with the MACRO detector

abstract:
  After a short overview of the MACRO detector, located at the Gran Sasso
Laboratory, I shall present and discuss the results on atmospheric muon
neutrino oscillations, concerning low (<E_nu> ~ 4 GeV) and high (<E_nu> ~ 50
GeV) energy data. Using the Multiple Coulomb Scattering of muons inside the
lower part of the detector, estimates of the neutrino energy were made event by
event for the high energy sample. The data on angular distributions, absolute
flux and L/E_nu distribution favor nu_mu <--> nu_tau oscillations with maximal
mixing and Delta m^2=2.5 x 10^-3 eV^2.


title: The NuMI Neutrino Beam and Potential for an Off-Axis Experiment

abstract:
  The Neutrinos at the Main Injector (NuMI) facility at Fermilab is under
construction and due to begin operations in late 2004. NuMI will deliver an
intense $\nu_{\mu}$ beam of variable energy 2-20 GeV directed into the Earth at
58 mrad. Several aspects of the design are reviewed, and potential limitations
to the ultimate neutrino flux are described. In addition, potential
measurements of neutrino mixing properties are described.


title: Off the Mass Shell: Electroweak Physics at NuTeV

abstract:
  The NuTeV collaboration has performed precision measurements of the ratio of
neutral current to charged current cross-sections in high rate, high energy
neutrino and anti-neutrino beams on a dense, primarily steel, target. The
separate neutrino and anti-neutrino beams, high statistics, and improved
control of other experimental systematics, allow the determination of
electroweak parameters with significantly greater precision than past
neutrino-nucleon scattering experiments. Our null hypothesis test of the
standard model prediction measures
sin2thetaW=0.2277+/-0.0013(stat)+/-0.0009(syst), a value which is 3 sigma above
the prediction. We discuss possible explanations for and implications of this
discrepancy.


title:
Study of Radiation Damage in Lead Tungstate Crystals Using Intense High
  Energy Beams

abstract:
  We report on the effects of radiation on the light output of lead tungstate
crystals. The crystals were irradiated by pure, intense high energy electron
and hadron beams as well as by a mixture of hadrons, neutrons and gammas. The
crystals were manufactured in Bogoroditsk, Apatity (both Russia), and Shanghai
(China). These studies were carried out at the 70-GeV proton accelerator in
Protvino.


title: Results on $\sin 2\phi_2 (\alpha)$ from the B Factories

abstract:
  The status of CP violation in $B^0\to \pi^+\pi^-$ and the determination of
$\sin 2\phi_2 (\alpha)$ from the $B$ factories is described.


title:
Measurement of hadronic cross section and preliminary results on the
  pion form factor using the radiative return at DAPHNE

abstract:
  In the fixed energy environment of the $e^{+}e^{-}$ collider DA$\Phi$NE, KLOE
can measure the cross section of the process $e^{+}e^{-} \to$ hadrons as a
function of the hadronic system energy using the radiative return. At energies
below 1 GeV, $e^{+}e^{-} \to \rho \to \pi^{+}\pi^{-}$ is the dominating
hadronic process. We report here on the status of the analysis for the
$e^{+}e^{-} \to \ppg$ channel, which allows to obtain a preliminary measurement
of the pion form factor using an integrated luminosity of $\sim73 pb^{-1}$.


title:
Search for Supersymmetric Particles with R-Parity Violating Decays in
  e+e- Collisions at sqrt{s} up to 209GeV

abstract:
  Searches for the pair production of supersymmetric particles under the
assumption that R-parity is violated via a single dominant LLEbar, LQDbar or
UbarDbarDbar coupling are performed using the data collected by the ALEPH
detector at LEP at centre-of-mass energies from 189 to 209GeV. The numbers of
observed candidate events in the data are in agreement with the Standard Model
expectation, and limits on the production cross sections and on the masses of
charginos, sleptons, squarks and sneutrinos are derived.


title: Search for supersymmetry, extra dimensions and exotic phenomena at LEP

abstract:
  The latest results on searches for supersymmetry, extra dimensions and exotic
phenomena from the LEP collaborations are presented. No significant signal-like
excess is observed in the data. The results are interpreted in various models
and robust constraints are placed.


title: Multi-Photon Production in e+e- collisions at sqrt(s) = 181 - 209 GeV

abstract:
  The process e+e- -> gamma gamma (gamma) is studied using data collected by
the OPAL detector at LEP between the years 1997 and 2000. The data set
corresponds to an integrated luminosity of 672.3pb-1 at centre-of-mass energies
lying between 181 GeV and 209 GeV. Total and differential cross- sections are
determined and found to be good agreement with the predictions of QED. Fits to
the observed angular distributions are used to set limits on parameters from
several models of physics beyond the Standard Model such as cut-off parameters,
contact interactions of the type e+e-gamma gamma, gravity in extra spatial
dimensions and excited electrons. In events with three photons in the final
state the mass spectrum of photon pairs is investigated. No narrow resonance
X-> gamma gamma is found and limits are placed on the product of the Xgamma
production cross-section and branching ratio.


title:
Multi-lepton Production at High Transverse Momentum in electron-proton
  collisions at HERA

abstract:
  Multi-electron and multi-muon production have been measured at high
transverse momentum in electron-proton collisions at HERA.Good overall
agreement is found with the Standard Model predictions, dominated by
photon-photon interactions. Events are observed with a di-electron mass above
100 GeV, a domain where the Standard Model prediction is low.


title: Precision Tests of QCD

abstract:
  The electron-proton collider HERA allows the study of the partonic content of
the proton in regions of Q-squared up to 50,000 GeV$^2$ and values of Bjorken-x
down to 10^-5. This paper presents recent precision measurements of structure
functions and hadronic final state observables which test QCD over this wide
region of phase space.


title: Atmospheric Neutrinos in 2002

abstract:
  In this talk, I will present a snapshot of key results regarding atmospheric
neutrinos, as of the summer of 2002. I will review the evidence for neutrino
oscillation, dominated by the large sample from Super-Kamiokande, but supported
by confirmation from MACRO and Soudan 2. I will then review some of the more
detailed inquiries made using Super-Kamiokande data such as alternative
scenarios, three-flavor oscillation, and tau neutrino appearance.


title: Status of MiniBooNE

abstract:
  MiniBooNE is a neutrino oscillation experiment now running at Fermilab. The
experiment will search for muon neutrino to electron neutrino oscillations in
order to make a conclusive statement about the yet-unconfirmed evidence for
oscillations presented by the LSND experiment. Preparations for the start of
running were completed over the summer of 2002, and MiniBooNE observed its
first neutrino events in late August.


title:
Search for GUT Magnetic Monopoles with the MACRO Experiment at the Gran
  Sasso Lab

abstract:
  The final results of the MACRO experiment on the search for GUT supermassive
magnetic monopoles in the penetrating cosmic radiation are presented and
discussed. The 90% CL upper limits are at the level of 1.5 - 2 x 10^-16 cm^-2
s^-1 sr^-1 for 0.0004 < beta < 1. Similar limits were obtained for nuclearites.
Limits for the MM catalysis of proton decay are at 3 - 4 x 10^-16 cm^-2 s^-1
sr^-2 for 10^-4 < beta < 6 x 10^-3.


title: SUSY Particles Searches at LEP and Interpretations within the MSSM

abstract:
  Searches for R-parity conserving supersymmetric particles have been performed
in e+e- data collected by LEP detectors, at centre-of-mass energies up to
209GeV, corresponding to an integrated luminosity of 3.1fb-1. The results and
their interpretation in the context of MSSM frameworks are briefly reviewed.


title:
Photoproduction of the $\omega$ meson on the proton at large momentum
  transfer

abstract:
  The differential cross section, $d\sigma/dt$ for $\omega$ meson exclusive
photoproduction on the proton above the resonance region ($2.6<W<2.9$ GeV) was
measured up to a momentum transfer $-t = 5$ GeV$^2$ using the CLAS detector at
Jefferson Laboratory. The $\omega$ channel was identified by detecting a proton
and $\pi^+$ in the final state and using the missing mass technique. While the
low momentum transfer region shows the typical diffractive pattern expected
from Pomeron and Reggeon exchange, at large $-t$ the differential cross section
has a flat behavior. This feature can be explained by introducing quark
interchange processes in addition to the QCD-inspired two-gluon exchange.


title:
Higher Twist, $\xi_w$ Scaling, and Effective $LO PDFs$ for Lepton
  Scattering in the Few GeV Region

abstract:
  We use a new scaling variable $\xi_w$, and add low $Q^2$ modifications to
GRV98 leading order parton distribution functions such that they can be used to
model electron, muon and neutrino inelastic scattering cross sections (and also
photoproduction) at both very low and high energies.


title:
Measurements of time dependent CP asymmetry in $B \to VV$ decays with
  BELLE

abstract:
  A study of CP violation in $B\to J/\psi K^*(K_S^0\pi^0)$ decays by time
dependent angular analysis is discussed. Status of time independent analyses
for other $B\to VV$ decays is also reported. The data used for the analyses are
taken with the Belle detector at KEK.


title: Measurement of Neutral-Current Four-Fermion Production at LEP2

abstract:
  Four-fermion final states qqbar e+e- and qqbar mu+mu- from neutral-current
interactions in e+e- collisions are studied in the OPAL detector at LEP at
centre-of-mass energies from 183 GeV to 209 GeV. The data analysed correspond
to a total integrated luminosity of about 650 pb-1 recorded from 1997 to 2000.
Corresponding to the acceptance of the OPAL detector, a signal definition is
applied requiring both leptons to have a scattering angle satisfying cos0
<0.95. Further requirements are made on the invariant masses of the fermion
pairs. The extracted cross-sections for the processes e+e- -> qqbar e+e- and
e+e- qqbar mu+mu- are consistent with the expectations from the Standard Model.


title: Inclusive Diffraction at HERA

abstract:
  New precision measurements of inclusive diffractive deep-inelastic ep
scattering interactions, performed by the H1 and ZEUS collaborations at the
HERA collider, are discussed. A new set of diffractive parton distributions,
determined from recent high precision H1 data, is presented.


title: N* and Meson Resonances in J/psi decays

abstract:
  Over sixty million J/psi events have been collected by the BES Collaboration
at the Beijing Electron-Positron Collider (BEPC). J/psi decays provide an
excellent place for studying excited nucleons and hyperons -- N*, $\Lambda^*$,
$\Sigma^*$ and $\Xi^*$ resonances, as well as meson resonances, including
possible glueballs and hybrids. Physics objectives, recent results and future
prospects of light hadron spectroscopy at BEPC are presented.


title: Leading proton production in e^+p collisions at HERA

abstract:
  Events with a final-state proton carrying a large fraction of the proton-beam
momentum, x_L>0.6, and the square of the transverse momentum p_T^2 <0.5 GeV^2,
have been studied in e^+p collisions with the ZEUS detector at HERA. Data with
different photon virtualities were used: Q^2<0.02 GeV^2, 0.1 <Q^2<0.74 GeV^2
and 3<Q^2<254 GeV^2.


title: Present Status of the K2K Experiment

abstract:
  New results from the K2K (KEK to Kamioka) long-baseline neutrino-oscillation
experiment is presented.


title:
Inclusive Analysis of the b Quark Fragmentation Function in Z Decays at
  LEP

abstract:
  A study of b quark hadronisation is presented using inclusively reconstructed
B hadrons in about four million hadronic Z decays recorded in 1992-2000 with
the OPAL detector at LEP. The data are compared to different theoretical
models, and fragmentation function parameters of these models are fitted. The
average scaled energy of weakly decaying B hadrons is determined to be
<xe>=0.7193+-0.0016(stat)+0.0036-0.0031(syst)


title: Structure Function Results from ZEUS

abstract:
  This contribution presents recent ZEUS results on proton structure functions
at HERA. The inclusive phi(1020)-meson cross section was measured, and it was
used to determine the s-quark content of the proton. The structure function F_2
was extracted using initial-state radiative events. Neutral and charged current
cross sections were used to extract the structure function xF_3 and measure the
mass of the W boson, respectively. A NLO QCD fit to ZEUS data and fixed target
cross sections was employed to determine the parton density functions of the
quarks and of the gluon inside the proton.


title: Study of CMS sensitivity to neutrinoless $\tau$ decay at LHC

abstract:
  The Large Hadron Collider (LHC), scheduled to start operation in 2006, is
foreseen to provide in the first year of running a total of $\sim 10^{12}$
$\tau$ leptons. CMS (Compact Muon Solenoid) is a general-purpose experiment
designed to study proton-proton and heavy-ion collisions at LHC. Even if the
Susy particles and Higgs searches togheter with the B-physics present its main
goal, the large amount of $\tau$-lepton, could allow a systematic study of
tau-physics. We have performed a full simulation of CMS using GEANT 3 package
and the object-oriented reconstruction program ORCA to study the sensitivity to
neutrinoless tau decay $\tau \to \mu^+ \mu^- \mu^- $ and $\tau \to \mu \gamma$.
We present the analysis developed for these channels and the results obtained.


title: Description of the Damn Yankee Controller (DYC)

abstract:
  Versions of the Damn Yankee Controller (DYC) have been used to read out
digitizers on the Fermilab E791, E835, FOCUS, SELEX, and KTeV experiments. The
DYC accepts 16-bit data and control signals from 10 MHz Emitter Coupled Logic
(ECL) PORT digitizing modules such as LeCroy CAMAC PCOS latches and FERA Analog
to Digital Converters (ADCs). Data is packed into First In First Out (FIFO)
memories as 32-bit longwords. Complete events including data, a leading word
count, and an Event Synchronization Number are transmitted to a data
destination. The DYC described here was meant to be simple and fast and was
designed and built in a period of three weeks.


title: Search for the Electric Dipole Moment of the tau lepton

abstract:
  We have searched for a T/CP violation signature arising from an electric
dipole form factor (d_tau) of the tau lepton in the e+e- -> tau+tau- reaction.
Using an optimal observable method for 29.5 fb^{-1} of data collected with the
Belle detector at the KEKB collider at sqrt{s}=10.58 GeV, we obtained the
preliminary result Re(d_tau) = (1.15 +- 1.70) x 10^{-17} ecm and Im(d_tau) =
(-0.83 +- 0.86) x 10^{-17} ecm for the real and imaginary parts of d_tau,
respectively, and set the 95% confidence level limits -2.2 < Re(d_tau) < 4.5
(10^{-17} ecm) and -2.5 < Im(d_tau) < 0.8 (10^{-17} ecm).


title: Search for Lepton Flavor-Violating "tau -> mu gamma" decay

abstract:
  We search for the lepton flavor-violating "tau -> mu gamma" decay using 29.7
million tau pairs accumulated by the Belle experiment. The main background
sources are found to be tau pairs with "tau -> mu nu nu" decay and radiative
dimuon events. One event is observed in the signal region, while 2.5 +- 0.6
background events are expected. A preliminary upper limit Br(tau -> mu gamma) <
6 x 10^{-7} at the 90% confidence limit is obtained.


title: Open charm B decays

abstract:
  New results on B decays to charm-related modes from the Belle and CLEO
experiments are presented.


title:
Novel Technique for Ultra-sensitive Determination of Trace Elements in
  Organic Scintillators

abstract:
  A technique based on neutron activation has been developed for an extremely
high sensitivity analysis of trace elements in organic materials. Organic
materials are sealed in plastic or high purity quartz and irradiated at the
HFIR and MITR. The most volatile materials such as liquid scintillator (LS) are
first preconcentrated by clean vacuum evaporation. Activities of interest are
separated from side activities by acid digestion and ion exchange. The
technique has been applied to study the liquid scintillator used in the KamLAND
neutrino experiment. Detection limits of <2.4X10**-15 g 40K/g LS, <5.5X10**-15
g Th/g LS, and <8X10**-15 g U/g LS have been achieved.


title: Hadronic structure in tau- -> pi- pi- pi+ neutrino decays

abstract:
  A model-dependent analysis of the hadronic substructure in tau- -> pi- pi-
pi+ neutrino decay is reported. The decay is dominated by the process tau- ->
a1(1260)- + neutrino, in which a1(1260)- -> rho0 pi- in an S-wave decay.
Amplitudes involving a1(1260) decays into isoscalars, especially a_1(1260)- ->
f0(600)pi-, are large. tau- -> pi- pi- pi+ neutrino decays via the pseudoscalar
pi(1300)- are small. These results support the resonant substructure reported
in the previously reported analysis of tau- -> pi0 pi0 pi- neutrino decay mode
from the same CLEO II data sample.


title: Determination of the B-bar --> D* l nu-bar Decay Width and |V_cb|

abstract:
  In the Standard Model, the charged current of the weak interaction is
governed by a unitary quark mixing matrix that also leads to CP violation.
Measurement of the Cabibbo-Kobayashi-Maskawa (CKM) matrix elements is essential
to searches for new physics, either through the structure of the CKM matrix, or
a departure from unitarity. We determine the CKM matrix element |Vcb| using a
sample of 3 x 10^6 B B-bar events in the CLEO detector at the Cornell Electron
Storage Ring. We determine the yield of reconstructed B0-bar --> D*+ l nu-bar
and B- --> D*0 l nu-bar decays as a function of w, the boost of the D* in the B
rest frame, and from this we obtain the differential decay rate dGamma/dw. By
extrapolating dGamma/dw to w=1, the kinematic end point at which the D* is at
rest relative to the B, we extract the product |Vcb|F(1), where F(1) is the
form factor at w=1. We find |Vcb| = 0.0431 +- 0.0013 (stat) +- 0.0018 (syst).
We combined |Vcb|F(1) with theoretical results for F(1) to determine |Vcb| =
0.0469 +- 0.0014(stat) +- 0.0020(syst) +- 0.0018(theo). We also integrate the
differential decay rate over w to obtain BF(B0-bar --> D*+ l nu-bar) = (6.09 +-
0.19 +- 0.40)% and BF(B- --> D*0 l nu-bar) = (6.50 +- 0.20 +- 0.43)%.


title: Search for Single Top Production at LEP

abstract:
  Single top production in e+e- annihilations is searched for in data collected
by the L3 detector at centre-of-mass energies from 189 to 209 GeV,
corresponding to a total integrated luminosity of 634 pb-1. Investigating
hadronic and semileptonic top decays, no evidence of single top production at
LEP is obtained and upper limits on the single top cross section as a function
of the centre-of-mass energy are derived. Limits on possible anomalous
couplings, as well as on the scale of contact interactions responsible for
single top production are determined.


title:
Final R-value results from 2-5 GeV from BES and QCD test with R scan
  data

abstract:
  Final results of the measurement of $R = \sigma(e^+e^- \to hadrons)
/\sigma(e^+e^- \to \mu^+\mu^-)$ in the energy region from 2 to 5 GeV with the
upgraded Beijing Spectrometer (BESII) at the Beijing Electron Positron Collider
(BEPC) are presented. Preliminary results of the inclusive momentum spectra and
second binomial moment measured with the $R$ scan data at 2.2, 2.6, 3.0, 3.2,
4.6 and 4.8 GeV are reported.


title: Search for Nearly Mass-Degenerate Charginos and Neutralinos at LEP

abstract:
  A search was performed for charginos with masses close to the mass of the
lightest neutralino in e+e- collisions at centre-of-mass energies of 189-209
GeV recorded by the OPAL detector at LEP. Events were selected if they had an
observed high-energy photon from initial state radiation, reducing the dominant
background from two-photon scattering to a negligible level. No significant
excess over Standard Model expectations has been observed in the analysed data
set corresponding to an integrated luminosity of 570pb-1. Upper limits were
derived on the chargino pair-productin cross-section, and lower limits on the
chargino mass were derived in the context of the Minimal Supersymmetric
Extension of the Standard Model for the gravity and anomaly mediated
Supersymmetry breaking scenarios.


title:
Cerenkov angle and charge reconstruction with the RICH detector of the
  AMS experiment

abstract:
  The Alpha Magnetic Spectrometer (AMS) experiment to be installed on the
International Space Station (ISS) will be equipped with a proximity focusing
Ring Imaging Cerenkov (RICH) detector, for measurements of particle electric
charge and velocity. In this note, two possible methods for reconstructing the
Cerenkov angle and the electric charge with the RICH, are discussed. A
Likelihood method for the Cerenkov angle reconstruction was applied leading to
a velocity determination for protons with a resolution of around 0.1%. The
existence of a large fraction of background photons which can vary from event
to event, implied a charge reconstruction method based on an overall efficiency
estimation on an event-by-event basis.


title: Test beam results of ATLAS Pixel Sensors

abstract:
  Silicon pixel detectors produced according to the ATLAS Pixel Detector design
were tested in a beam at CERN in the framework of the ATLAS collaboration. The
detectors used n+/n sensors with oxygenated silicon substrates. The
experimental behaviour of the detectors after irradiation to 1.1 10**15
n_eq/cm**2 and 600 kGy is discussed. At the sensor bias voltage of 600 V the
depleted depth is measured to be 229 um, the mean collected charge is 20000
electrons, the detection efficiency is 98.2% and the spatial resolution is 9.6
um


title:
Study of spectral moments in semileptonic decays of the b hadron with
  the DELPHI detector at LEP

abstract:
  The measurement of the moments of hadronic mass spectrum and of lepton energy
spectrum based on a sample of semileptonic decays of the b hadron selected from
$Z^0 \to b \bar b$ events recorded with the DELPHI detector at LEP, are
presented. These results are interpreted in terms of constraints on the quark
masses and on the b-quark kinetic energy value.


title:
The $Q^2$-dependence of the generalised Gerasimov-Drell-Hearn integral
  for the deuteron, proton and neutron

abstract:
  The Gerasimov-Drell-Hearn (GDH) sum rule connects the anomalous contribution
to the magnetic moment of the target nucleus with an energy-weighted integral
of the difference of the helicity-dependent photoabsorption cross sections. The
data collected by HERMES with a deuterium target are presented together with a
re-analysis of previous measurements on the proton. This provides a measurement
of the generalised GDH integral covering simultaneously the nucleon-resonance
and the deep inelastic scattering regions. The contribution of the
nucleon-resonance region is seen to decrease rapidly with increasing $Q^2$. The
DIS contribution is sizeable over the full measured range, even down to the
lowest measured $Q^2$. As expected, at higher $Q^2$ the data are found to be in
agreement with previous measurements of the first moment of $g_1$. From data on
the deuteron and proton, the GDH integral for the neutron has been derived and
the proton--neutron difference evaluated. This difference is found to satisfy
the fundamental Bjorken sum rule at $Q^2 = 5$ GeV$^2$.


title:
First Observation of the Exclusive Decays Lambda_c to Lambda
  pi+pi+pi-pi0 and Lambda_c to Lambda omega pi+

abstract:
  Using data recorded by the CLEO III detector at CESR, we report on the first
measurements of the branching fractions for decays of the Lambda_c^+ charmed
baryon into (Lambda pi+ pi+ pi- pi0) and (Lambda omega pi+). All rates are
measured with respect to the p K- pi+ decay mode. The relative branching
fractions are 0.39 +- 0.09(stat.) +- 0.09(syst.) and 0.24 +- 0.06(stat.) +-
0.06(syst.) for the (Lambda pi+ pi+ pi- pi0) and (Lambda omega pi+) modes,
respectively. The data also suggest decays of the Lambda_c^+ via (Lambda eta
pi+, eta --> pi+ pi- pi0) with a rate which is consistent with previous
measurements of the branching fraction of Lambda_c^+ to (Lambda eta pi+, eta
--> gamma gamma). The measurements indicate that the omega and eta sub-modes
comprise 87+-13% of the (Lambda pi+ pi+ pi- pi0) final state. We set an upper
limit on the contribution from non-omega and non-eta modes of 0.13 at the 90%
confidence level.


title: Recent results on the helicity structure of the nucleon from HERMES

abstract:
  The HERMES experiment has measured double spin asymmetries of inclusive and
semi-inclusive cross sections for the production of charged hadrons in
deep-inelastic scattering of polarised positrons on polarised hydrogen and
deuterium targets, in the kinematic range 0.023 < x < 0.6, and 1 GeV^2 < Q^2 <
15 GeV^2. For the data taken on the deuterium target, a RICH detector provides
the complete identification of charged pions and kaons. From the inclusive
measurements on deuterium, the polarised structure function g_1^d has been
extracted with high precision. Together with the semi-inclusive measurements,
quark polarisations are extracted separately for the u, ubar, d, dbar, and (s +
sbar) flavours in a LO QCD analysis. Furthermore, a possible breaking of
flavour symmetry in the polarised light sea, (Delta ubar - Delta dbar), was
measured for the first time and found to be consistent with zero within the
experimental precision.


title: Direct neutrino mass search

abstract:
  With the compelling evidence for massive neutrinos from recent neutrino
oscillation experiments, one of the most fundamental tasks of particle physics
over the next years will be the determination of the absolute mass scale of
neutrinos, which has crucial implications for cosmology, astrophysics and
particle physics. Neutrino oscillation experiments can measure squared mass
differences but not masses. The latter have to be determined in a different
way. The direct mass experiments investigate -- besides time-of-flight
measurements -- the kinematics of weak decays obtaining information on the
neutrino mass without further requirements. Here the tritium beta decay
experiments give the most stringent results. The current tritium beta decay
experiments at Mainz and Troitsk are reaching their sensitivity limit. The
different options for a next generation direct neutrino mass experiment with
sub-eV sensitivity are discussed. The KATRIN experiment, which will investigate
the tritium beta spectrum with a MAC-E-Filter of 1 eV resolution, is being
prepared to reach a sub-eV sensitivity.


title:
The Hadron Hose: Continuous Toroidal Focusing for Conventional Neutrino
  Beams

abstract:
  We have developed a new focusing system for conventional neutrino beams. The
``Hadron Hose'' is a wire located in the meson decay volume, downstream of the
target and focusing horns. The wire is pulsed with high current to provide a
toroidal magnetic field which continuously focuses mesons. The hose increases
the neutrino event rate and reduces differences between near-field and
far-field neutrino spectra for oscillation experiments. We have studied this
device as part of the development of the Neutrinos at the Main Injector (NuMI)
project, but it might also be of use for other conventional neutrino beams.


title: Particle Physics at Future Colliders

abstract:
  The search for physics beyond the Standard Model motivates new high-energy
accelerators, which will require high luminosities in order to produce
interesting new heavy particles. Using the Higgs boson and supersymmetry as
examples, we discuss the capabilities of the LHC and $e^+ e^-$ linear colliders
in the TeV and multi-TeV energy ranges to discover and study new particles.


title:
Precise measurements of the KS->gamma gamma and KL->gamma gamma decay
  rates

abstract:
  The KS->gamma gamma decay rate has been measured with the NA48 detector using
a high intensity short neutral beam from the CERN SPS. The measured branching
ratio BR(KS->gamma gamma)=(2.78+-0.06(stat)+-0.04(syst))x10-6, obtained from
7461+-172 KS->gamma gamma events, is significantly higher than the O(p^4)
prediction of Chiral Perturbation Theory. Using a KL beam the ratio
BR(KL->gamma gamma)/BR(KL->3pi0)=(2.81+-0.01(stat)+-0.02(syst))x10-3 has been
measured.


title:
Measurement of $ep \to e^{'}p\pi^{+}\pi^{-}$ and baryon resonance
  analysis

abstract:
  The cross section for the reaction $ e p \to e^{\prime} p \pi^{+} \pi^{-}$
was measured in the resonance region for 1.4$<$W$<$2.1 GeV and 0.5$<Q^{2}<$1.5
GeV$^{2}$/c$^{2}$ using the CLAS detector at Jefferson Laboratory. The data
shows resonant structures not visible in previous experiments. The comparison
of our data to a phenomenological prediction using available information on
$N^{*}$ and $\Delta$ states shows an evident discrepancy. A better description
of the data is obtained either by a sizeable change of the properties of the
$P_{13}$(1720) resonance or by introducing a new baryon state, not reported in
published analyses.


title: Other Atmospheric Neutrino Experiments

abstract:
  The history and recent progress of atmospheric neutrinos are reviewed. An
emphasis is placed on results from experiments other than Super-Kamiokande.


title: Search for the K(L) --> PI0 PI0 E+ E- Decay in the KTeV Experiment

abstract:
  The recent discovery of a large CP violating asymmetry in K(L) --> PI+ PI- E+
E- mode has prompted us to seach for the associated K(L) --> PI0 PI0 E+ E-
decay mode in the KTeV-E799 experiment at Fermilab. In 2.7E+11 K(L) decays, one
candidate event has been observed with an expected background of 0.3 event,
resulting in an upper limit for the K(L) --> PI0 PI0 E+ E- branching ratio of
6.6E-09 at the 90% confidence level.


title: Beam Simulation Tools for Geant4

abstract:
  Geant4 is a tool kit developed by a collaboration of physicists and computer
professionals in the High Energy Physics field for simulation of the passage of
particles through matter. The motivation for the development of the Beam Tools
is to extend the Geant4 applications to accelerator physics. Although there are
many computer programs for beam physics simulations, Geant4 is ideal to model a
beam going through material or a system with a beam line integrated to a
complex detector. There are many examples in the current international High
Energy Physics programs, such as studies related to a future Neutrino Factory,
a Linear Collider, and a very Large Hadron Collider.


title: CLEO Contributions to Tau Physics

abstract:
  We review many of the contributions of the CLEO experiment to tau physics.
Topics discussed are: branching fractions for major decay modes and tests of
lepton universality; rare decays; forbidden decays; Michel parameters and spin
physics; hadronic sub-structure and resonance parameters; the tau mass, tau
lifetime, and tau neutrino mass; searches for CP violation in tau decay; tau
pair production, dipole moments, and CP violating EDM; and tau physics at
CLEO-III and at CLEO-c.


title: Photon and electron structure from e+e- interactions

abstract:
  The status of the measurements and the theoretical developments concerning
the hadronic structure of the photon are briefly summarised.


title: Mixing in the D0 - D0bar system at BaBar

abstract:
  We report a preliminary result for D0-D0bar mixing and the doubly Cabibbo
suppressed decay rate R_D based on an analysis of D0 -> K+ pi- decays from 57.1
inverse fb of data collected at or just below the Y(4S) resonance with the
BaBar detector at the PEP-II collider. We set 95% confidence limits for the
mixing parameters x'^2 and y' and find that our result is compatible with no
mixing and no CP violation. In the limit of no mixing we find the doubly
Cabibbo suppressed decay rate R_D = (0.357 +- 0.022 (stat.) +- 0.027 (syst.))%
and the CP violating asymmetry A_D = 0.095 +- 0.061 (stat.) +- 0.083 (syst.).


title: Standard Model Explanations for the NuTeV Electroweak Measurements

abstract:
  The NuTeV Collaboration has measured the electroweak parameters sin^2 theta_W
and rho in neutrino-nucleon deep-inelastic scattering using a sign-selected
beam. The nearly pure neutrino or antineutrino beams that result provide many
of the cancellations of systematics associated with the Paschos-Wolfenstein
relation. The extracted result for sin^2 theta_W(on-shell) is three standard
deviations from prediction. We discuss Standard Model explanations for the
puzzle.


title:
The Contribution of One-Photon Annihilation at psi(2S) in e+e-
  Experiment

abstract:
  The continuum one-photon annihilation at psi(2S) in e+e- experiment is
studied. Such contributions to the measured final state omega pi0 and pi+pi- at
psi(2S) mass are estimated by phenomenological models. It is found that these
contributions must be taken into account in the determination of branching
ratios of psi(2S) --> omega pi0 and psi(2S) --> pi+ pi-, as well as other
electromagnetic decay modes. The study reaches the conclusion that in order for
BES to obtain the correct branching ratios on these decay modes, at least 10
inverse pb of data below the psi(2S) peak is needed.


title:
The interference between virtual photon and 1-- charmonium in
  e+e-experiment

abstract:
  e+e- Experiments producing charmonium are reviewed. It is found that the
contribution of the continuum amplitude via virtual photon was neglected in
almost all the experiments and the channels analyzed. It is shown that the
contribution of the continuum part may affect the final results significantly
in psi(2S) and psi(3770) decays, while the interference between continuum and
resonance amplitudes may even affect the J/psi decays as well as the psi(2S)
and psi(3770). This should be considered in analyzing the "rho-pi puzzle"
between J/psi and psi(2s) decays, and the difference between inclusive hadron
and DDbar cross sections in psi(3770) decays.


title:
Study of the azimuthal asymmetry of jets in neutral current deep
  inelastic scattering at HERA

abstract:
  The azimuthal distribution of jets produced in the Breit frame in high-Q**2
deep inelastic e+p scattering has been studied with the ZEUS detector at HERA
using an integrated luminosity of 38.6 pb-1. The measured azimuthal
distribution shows a structure that is well described by next-to-leading-order
QCD predictions over the Q**2 range considered, Q**2>125 GeV**2.


title: Some Developments in Light Quark Spectroscopy

abstract:
  Among the many unresolved questions in light quark spectroscopy, the
underlying structure of the scalar mesons and the identification of states with
a gluonic content rank high. Recently, new information has come from $\phi$
radiative decays, $J/\psi$, $\tau$, $D$ and $D_s$ meson decays. Other papers in
this conference review radiative transitions of $\phi$ and $J/\psi$. This paper
discusses new information on the scalar sector primarily that from decays of
$D$ and $D_s$ mesons.


title: Search for the Electric Dipole Moment of the tau Lepton

abstract:
  We have searched for a CP violation signature arising from an electric dipole
moment (d_tau) of the tau lepton in the e+e- -> tau+tau- reaction. Using an
optimal observable method and 29.5 fb^{-1} of data collected with the Belle
detector at the KEKB collider at sqrt{s} = 10.58 GeV, we find Re(d_tau) = (1.15
+- 1.70) x 10^{-17} ecm and Im(d_tau) = (-0.83 +- 0.86) x 10^{-17} ecm and set
the 95% confidence level limits -2.2 < Re(d_tau) < 4.5 (10^{-17}ecm) and -2.5 <
Im(d_tau) < 0.8 (10^{-17}ecm).

Erratum to: "Nuclear Effects on R=\sigma_L/\sigma_T in Deep-Inelastic
  Scattering" Phys.Lett. B475(2000)386

abstract:
  This erratum revokes the main conclusion of a Letter that reported
measurements of cross sections for deep-inelastic scattering (DIS) of leptons
on $^3$He and $^{14}$N targets, expressed as ratios of $\sigma_A / \sigma_D$ to
the cross section on the deuterium target.


title:
Measurement of R=\sigma_L/\sigma_T in Deep-Inelastic Scattering on
  Nuclei

abstract:
  Cross section ratios for deep-inelastic scattering from $^3$He, $^{14}$N and
$^{84}$Kr with respect to $^2$H have been measured by the HERMES collaboration
at DESY using a 27.5 GeV positron beam. The data cover a range in the Bjorken
scaling variable $x$ between 0.010 and 0.65, the negative squared four-momentum
transfer $Q^2$ varies from 0.5 to 15 GeV$^2$, while at small values of $x$ and
$Q^2$, the virtual photon polarisation parameter $\epsilon$ extends to lower
values than previous measurements. From the dependence of the data on
$\epsilon$, values for $R_A/R_D$ with $R$ the ratio $\sigma_L / \sigma_T$ of
longitudinal to transverse DIS cross sections have been derived and found to be
consistent with unity. %The data are compared to measurements performed by NMC,
E665, and SLAC %on $^4$He and $^{12}$C, and are found to be different for %$x
<$ 0.06 and $Q^2 <$ 1.5 GeV$^2$.


title:
Very Long Baseline Neutrino Oscillation Experiment for Precise
  Determination of Oscillation Parameters and Search for nu_mu -> nu_e
  Appearance and CP Violation

abstract:
  The possibility of making a low cost, very intense (1MW) high energy proton
source at the Brookhaven Alternating Gradient Synchrotron (BNL-AGS) along with
the forthcoming new large underground detectors (approaching 1 MT in mass) at
the National Underground Science and Engineering Laboratory (NUSEL) in
Homestake, South Dakota or at the Waste Isolation Pilot Plant (WIPP) in
Carlsbad, New Mexico, allows us to propose a program of experiments that will
address fundamental aspects of neutrino oscillations and CP-invariance
violation. This program is unique because of the very long baseline of more
than 2500 km from BNL to the underground laboratory in the West. We used the
running scenario of a low energy, wide band neutrino beam with 1 MW AGS, 500 kT
of fiducial mass water Cherenkov detector, and 5x10^7 seconds of running time.
In this report we show that with these conditions we precisely measure dm^2_32
and sin^2(2theta_23) and have excellent sensitivity to sin^2(2theta_13) with a
distinctive signal spectrum. If sin^2(2theta_13) > 0.01 the experiment is
sensitive to the CP-violating phase in the mixing matrix with only neutrino
running. By running in the anti-neutrino mode we distinguish between the cases
dm^2_31 > 0 versus dm^2_31 < 0 using distinctive distortions to the electron or
positron spectrum. Lastly, the very long baseline allows the measurement of
dm^2_21 (in the LMA region) with approximately the same resolution as KAMLAND
but in the nu_mu -> nu_e appearance channel.


title: A Run Scenario for the Linear Collider

abstract:
  We outline a run plan and examine the precision with which supersymmetric and
Higgs parameters may be determined in 1000 inverse femtobarns of running at the
nominal 500 GeV electron-positron linear collider, assuming the Snowmass
benchmark mSUGRA point SM2 (similar to the SPS1 benchmark).


title: LEP, SLC and the Standard Model

abstract:
  The period 1989-2000 provided a huge yield of precise electroweak data from
the LEP and SLC experiments. Many analyses of these data are now complete, but
others, particularly of the full LEP-2 data samples, continue. The main
electroweak physics results from these data are summarised, and stringent tests
of the Standard Model are made with the combined samples. The direct search for
the missing link of the Standard Model, the Higgs boson, is also briefly
reviewed.


title:
Study of the Process $e^+e^- \to K^0_L K^0_S$ in the C.M.Energy Range
  1.05-1.38 GeV with CMD-2

abstract:
  The process $e^+e^- \to K^0_L K^0_S$ has been studied with the CMD-2 detector
using about 950 events detected in the center-of-mass energy range from 1.05 to
1.38 GeV. The cross section exceeds the expectation based on the contributions
of the rho(770), omega(782) and phi(1020) mesons only.


title: Status and Prospectives of Hadronic Cross Section at Low Energy

abstract:
  In this talk I will review the experimental status and the prospects for the
future of $\sigma(e^+ e^- \to hadrons)$ at low energy. The recent preliminary
results obtained by KLOE and BABAR collaborations using the radiative return
will be also discussed.


title: Neutron-Antineutron Oscillations

abstract:
  Experimental observation of nucleon instability is one of the missing key
components required for the explanation of baryon asymmetry of the universe.
Proton decays with the modes and rates predicted by(B-L)-conserving schemes of
Grand Unification are not observed experimentally. There are reasons to believe
that (B-L) might not be conserved in nature, thus leading to the nucleon decay
into lepton+(X) and to phenomena such as Majorana masses of neutrinos,
neutrinoless double-beta decays, and most spectacularly to the transitions of
neutron to anti-neutron. The energy scale where (B-L) violation takes place
cannot be predicted by theory and therefore has to be explored by experiments.
Different experimental approaches to searching for (B-L)-violating transition
of neutron to antineutron are discussed in this paper. Most powerful search for
neutron to antineutron transitions can be performed in a new reactor-based
experiment at HFIR reactor (ORNL) where sensitivity can be >1,000 times higher
than in the previous experiments.


title:
Charged particle multiplicities in heavy and light quark initiated
  events above the Z0 peak

abstract:
  We have measured the mean charged particle multiplicities separately for
bbbar, ccbar and light quark (uubar, ddbar, ssbar) initiated events produced in
e+e- annihilations at LEP. The data were recorded with the OPAL detector at
eleven different energies above Z0 peak, corresponding to the full statistics
collected at LPE1.5 and LEP2. The difference in mean charged and particle
multiplicities for bbbar and light quark events, delta_bl, measured over this
energy range is consistent with an energy independent behaviour, as predicted
by QCD, but is inconsistent with the prediction of a more phenomenological
approach which assumes that the multiplicity accompanying the decay of a heavy
quark is independent of the quark mass itself. Our results, which can be
combined into the single measurement delta_bl = 3.44+-0.40(stat)+-0.89(syst) at
a luminosity weighted average centre-of mass energy of 195 GeV, are also
consistent with an energy independent behaviour as extrapolated from lower
energy data.


title:
Hard Exclusive Electroproduction of Two Pions off Proton and Deuteron at
  HERMES

abstract:
  Exclusive electroproduction of $\pi^+\pi^-$ pairs off hydrogen and deuterium
targets has been studied with the HERMES experiment. The angular distribution
of the $\pi^+$ in the $\pi^+\pi^-$ rest system has been studied in the
invariant mass range $0.3 < m_{\pi\pi} <1.5$ GeV.
  Theoretical models derived in the framework of the Generalized Parton
Distributions show that this angular distribution receives only contributions
from the interference between the isoscalar channel I=0 and the isovector
channel I=1.

Summary and Highlights of the 14th Topical Conference on Hadron Collider
  Physics (HCP2002)

abstract:
  Conference summary presentation given at HCP2002, Karlsruhe, Germany, Sep
29-Oct 4, 2002.


title: Study of charge multiplicity in hadronic three-jet Z decays at LEP

abstract:
  The mean charge multiplicity in hadronic three-jet Z decays has been measured
with the DELPHI detector as a function of the event topology and compared with
recent theoretical calculations. The QCD colour factor ratio C_A/C_F was
determined, and the gluon contribution to this multiplicity was extracted
giving a measurement of the mean charge multiplicity of a two-gluon
colour-singlet system as a function of the effective c.m. energy covering the
range from 16 to 52 GeV.


title: Measurements of inelastic J/psi and psi' photoproduction at HERA

abstract:
  The cross sections for inelastic photoproduction of J/psi and psi' mesons
have been measured in ep collisions with the ZEUS detector at HERA, using an
integrated luminosity of 38.0 pb-1. The events were required to have 0.1 < z <
0.9 and 50 < W < 180 GeV, where z is the fraction of the incident photon energy
carried by the J/psi in the proton rest frame and W is the photon-proton
centre-of-mass energy. The psi' to J/psi cross-section ratio was measured in
the range 0.55 < z < 0.9. The J/psi data, for various ranges of transverse
momentum, are compared to theoretical models incorporating colour-singlet and
colour-octet matrix elements. Predictions of a next-to-leading-order
colour-singlet model give a good description of the data, although there is a
large normalisation uncertainty. The J/psi helicity distribution for z > 0.4 is
compared to leading-order QCD predictions.


title: $\alpha_s$ 2002

abstract:
  An update of measurements of the strong coupling constant $\alpha_s$ is
given, representing the status of September 2002. The results convincingly
prove the energy dependence of $\alpha_s$ and are in excellent agreement with
the expectations of Quantum Chromodynamics, QCD. Evolving all results to the
rest energy of the $Z^0$ boson, the new world average of $\alpha_s(M_Z)$ is
determined from measurements which are based on QCD calculations in complete
NNLO perturbation theory, giving $$ \alpha_s(M_Z) = 0.1183 \pm 0.0027 . $$


title: Solar Neutrino Observations at the Sudbury Neutrino Observatory

abstract:
  The Sudbury Neutrino Observatory (SNO) is a 1000-tonne heavy water Cherenkov
detector. Its usage of \dto as target allows the simultaneous measurements of
the $\nu_e$ flux from $^8$B decay in the Sun and the total flux of all active
neutrino species through the charged-current and the neutral-current
interactions on the deuterons. Assuming the standard $^{8}$B shape, the $\nu_e$
component of the $^{8}$B solar neutrino flux is measured to be $\phi_e =
1.76^{+0.05}_{-0.05}{(stat.)}^{+0.09}_{-0.09} {(syst.)} x 10^6 {\rm cm}^{-2}
{\rm s}^{-1}$ for a kinetic energy threshold of 5 MeV. The non-\nue component
is found to be $\phinumutau = 3.41^{+0.45}_{-0.45}{(stat.)}^{+0.48}_{-0.45}
{(syst.)} x 10^6 {\rm cm}^{-2} {\rm s}^{-1}$. This $5.3\sigma$ difference
provides strong evidence for $\nu_{e}$ flavor transformation in the solar
neutrino sector. The total active neutrino flux is measured with the
neutral-current reaction at a neutrino energy threshold of 2.2 MeV. This flux
is determined to be $\phi_{NC} = 5.09^{+0.44}_{-0.43}{(stat.)}^{+0.46}_{-0.43}
{(syst.)} x 10^6 {\rm cm}^{-2} {\rm s}^{-1}$, and is consistent with solar
model predictions. Assuming an undistorted $^8$B spectrum, the night minus day
rate is 14.0$\pm$6.3(stat.)$^{+1.5}_{-1.4}$(sys.)\% of the average rate in the
charged-current channel. If the total active neutrino flux is constrained to
have no asymmetry, the night-day asymmetry in the $\nu_e$ flux is found to be
7.0$\pm$4.9(stat.)$^{+1.3}_{1.2}$(sys.)\%. A global analysis of all the
available solar neutrino data in terms of matter-enhanced oscillations of two
active flavors strongly favors the Large Mixing Angle (LMA) solution.


title: A First Measurement of the Tensor-Polarized Structure Function b1d

abstract:
  The Hermes experiment studies the spin structure of the nucleon using the
27.6 GeV longitudinally polarized positron beam of HERA and an internal target
of pure gases. In addition to the well-known spin structure function g_1,
measured precisely with longitudinally polarized proton and deuteron targets,
the use of a tensor-polarized deuteron target provides access to the tensor
polarized structure function b1d. The latter, measured with an unpolarized
beam, quantifies the dependence of the parton momentum distribution on the
nucleon spin. Hermes had a 1-month dedicated run with a tensor polarized
deuterium target during the 2000 data taking period. Here preliminary results
on the tensor-polarized structure function b1d are presented for the kinematic
range 0.002<x<0.85 and 0.1<Q^2<20 GeV^2.


title: New Limits on Naturally Occurring Electron Capture of 123Te

abstract:
  Electron capture of 123Te from the K shell has been investigated in a new
underground search with an array of 340 g TeO_2 thermal detectors. We find that
some previous indication of this decay could be attributed to E.C. of 121Te
resulting from neutron activation of natural Tellurium. There is therefore so
far no evidence for E.C. of 123Te from the K shell with a 90 % c.l. lower limit
t_{1/2}^K > 5.E19 years on the half lifetime. Taking into account the predicted
K E.C. branching ratio, the corresponding lower limit on the 123Te EC half
lifetime is t_{1/2} > 9.2E16 y, which can be theoretically interpreted only on
the basis of a strong suppression of the nuclear matrix elements. A
complementary analysis based on the expected fraction of E.C. accompanied by
internal bremsstrahlung is discussed.


title: HERA results on the structure of the proton

abstract:
  A selection of results from the H1 and ZEUS experiments at HERA are reviewed,
particularly in the area of deep inelastic scattering and diffraction. Quantum
chromodynamics gives a good explanation of these data down to surprisingly low
values of the four-momentum transfer, $Q^2$. Data at smaller $Q^2$ can be
described by Regge models as well as by dipole models including
parton-saturation effects. The latter can also give a unified description of
many features of diffractive data.


title: Search for neutrinoless tau decays tau -> 3l and tau -> l K0S

abstract:
  Neutrinoless tau-lepton decays into either three leptons (tau- -> l1- l2 l3)
or one lepton and one K0S meson(tau- -> l- K0S) where lepton l means either an
electron or muon, have been searched for using 48.6 fb^{-1} of data collected
with the Belle detector at the KEKB e+e- collider. No evidence for candidate
decays are found in any channel. Therefore we set 90% confidence level upper
limits on the branching fraction for 8 different decay modes. These limits are
more stringent than those set previously and reach to the 10^{-7} level.


title: Design and test results of the AMS RICH detector

abstract:
  The AMS-02 detector will operate for at least 3 years on the International
Space Station, measuring cosmic ray spectra at about 400 km above sea level
over a wide range of geomagnetic latitude.
  The proximity focusing ring imaging \v{C}erenkov counter of AMS-02 will
measure the particle velocity $\beta$ with $\approx 0.1%$ uncertainty, making
possible to discriminate Beryllium isotopes up to about 15 GeV/nucl. In
addition its charge measurement will allow to study the elemental composition
of cosmic rays up to Iron. A prototype of the RICH detector was tested with
cosmic rays and on a ion beam accelerated by SPS, at CERN (October 2002).


title: A Multi-variate Discrimination Technique Based on Range-Searching

abstract:
  We present a fast and transparent multi-variate event classification
technique, called PDE-RS, which is based on sampling the signal and background
densities in a multi-dimensional phase space using range-searching. The
employed algorithm is presented in detail and its behaviour is studied with
simple toy examples representing basic patterns of problems often encountered
in High Energy Physics data analyses. In addition an example relevant for the
search for instanton-induced processes in deep-inelastic scattering at HERA is
discussed. For all studied examples, the new presented method performs as good
as artificial Neural Networks and has furthermore the advantage to need less
computation time. This allows to carefully select the best combination of
observables which optimally separate the signal and background and for which
the simulations describe the data best. Moreover, the systematic and
statistical uncertainties can be easily evaluated. The method is therefore a
powerful tool to find a small number of signal events in the large data samples
expected at future particle colliders.


title:
AFM pictures of the surfaces of glass RPC electrodes damaged by water
  vapor contamination

abstract:
  We present surface pictures of the damaged electrodes from the Glass
Resistive Plate Chambers (GRPCs) taken by an Atomic Force Microscope (AFM). For
the test, a set of chambers were operated with freon mixed gas (damaged) and
freonless gas (not damaged), contaminated with 1000 to 2000 ppm of water vapor.
In the AFM pictures, clear differences in damage are seen between the
electrodes in the chambers with the freon mixed gas and the freonless gas; a
combination of freon and water vapor caused the damage.


title:
Questions about the Measurement of the $\rm{e}^{+}\rm{e}^{-}$ Luminosity
  Spectrum at a future linear Collider

abstract:
  Important analyses at a future linear collider, including top-quark and
W-boson mass measurements will depend upon the precise determination of the
luminosity spectrum. This can be done, in principle,in the planned detectors.
We review the problems to be solved, both beam-related and detector-related.


title: Study of $\bar{B^{0}} \to D^{(*)0} \pi^+ \pi^-$ Decays

abstract:
  We report on a study of $\bar{B^{0}} \to D^{(*) 0} \pi^+ \pi^-$ decays using
29.1 fb$^{-1}$ of $e^{+}e^{-}$ annihilation data recorded at the $\Upsilon(4S)$
resonance with the Belle detector at the KEKB storage ring. Making no
assumptions about the intermediate mechanism, the branching fractions for
$\bar{B}^0 \to D^0 \pi^+ \pi^-$ and $\bar{B}^0 \to D^{* 0} \pi^+ \pi^-$ are
determined to be $(8.0 \pm 0.6 \pm 1.5) \times 10^{-4} $ and $ (6.2 \pm 1.2 \pm
1.8) \times 10^{-4}$ respectively. An analysis of $\bar{B^{0}} \to D^{0} \pi^+
\pi^-$ candidates yields to the first observation of the color-suppressed
hadronic decay $\bar{B}^0 \to D^0 \rho^0$ with the branching fraction $(2.9 \pm
1.0 \pm 0.4) \times 10^{-4}$. We measure the ratio of branching fractions
${\mathcal B}(\bar{B^0} \to D^0 \rho^0) / {\mathcal B}(\bar{B^0} \to D^0
\omega)$ = 1.6 $\pm$ 0.8.


title: CDF Run I SUGRA Results

abstract:
  We present the most recent results of searches for physics beyond the
Standard Model using the CDF and D0 detector in the contest of Supersymmetry
(SUSY) with Supergravity (SUGRA) constraints. All results described correspond
to analysis performed using the past 1992-1996 Fermilab Tevatron Run I data
(roughly 110pb-1 per each experiment). In particular we report on searches for
stop decay in tau channel assuming R-Parity violation; searches for R-Parity
Violating LSP decays in di-muon plus 4 jets channel; searches for resonant
slepton production in R-Parity Violating mSUGRA; searches for mSUGRA in single
electron channel assuming R-Parity Conservation and searches for stop decay in
3-4 bodies.


title: Measuring the hadronic cross section via radiative return

abstract:
  Recently it has been demonstrated that particle factories, such as DAPHNE and
PEP-II, operating at fixed center-of-mass energies, are able to measure
hadronic cross sections as a function of the hadronic system energy using the
raditive return. This paper is an experimental overview of the progress in this
aera. Preliminary results from KLOE for the process e+e- -> \rho \gamma ->
\pi+\pi-\gamma and a fit to the pion form factor are presented. Some first
results from the BABAR collaboration are also shown.


title:
Observation of the strange sea in the proton via inclusive Phi-meson
  production in neutral current deep inelastic scattering at HERA

abstract:
  Inclusive phi-meson production in neutral current deep inelastic e+p
scattering has been measured with the ZEUS detector at HERA using an integrated
luminosity of 45 pb^{-1}. The phi mesons were studied in the range 10<Q2<100
GeV2, where Q2 is the virtuality of the exchanged photon, and in restricted
kinematic regions in the transverse momentum, p_T, pseudorapidity, eta, and the
scaled momentum in the Breit frame, x_p. Monte Carlo models with the
strangeness-suppression factor as determined by analyses of e+e- annihilation
events overestimate the cross sections. A smaller value of the
strangeness-suppression factor reduces the predicted cross sections, but fails
to reproduce the shapes of the measured differential cross sections.
High-momentum phi mesons in the current region of the Breit frame give the
first direct evidence for the strange sea in the proton at low x.


title: Status of the MINOS experiment

abstract:
  I will present the status of the long baseline neutrino oscillation
experiment MINOS at Fermi National Accelerator Laboratory (Fermilab). I will
summarize the status of the detector and beam construction, the expected event
rates and sensitivity to physics. I will also comment on possible future plans
to improve the performance of the experiment.


title: Search for Neutrinoless Tau Decays Involving the K0 Meson

abstract:
  We have searched for lepton flavor violating decays of the tau lepton with
one or two KS0 mesons in the final state. The data used in the search were
collected with the CLEO II and II.V detectors at the Cornell Electron Storage
Ring (CESR) and correspond to an integrated luminosity of 13.9 fb^-1 at the
Upsilon(4S) resonance. No evidence for signals were found, therefore we have
set 90% confidence level (C.L.) upper limits on the branching fractions B(tau
-> e KS0) < 9.1e-7, B(tau -> muKS0) < 9.5e-7, B(tau -> e 2KS0) < 2.2e-6, and
B(tau -> mu 2KS0) < 3.4e-6. These represent significantly improved upper limits
on the two-body decays and first upper limits on the three-body decays.


title: CDF Run II Status and prospects

abstract:
  Run II at the Tevatron Collider started at the beginning of March 2001. With
extensive upgrades on both detectors and electronics the CDF II began to
collect data. This paper reviews early Run II physics results obtained by
analyzing data collected before the middle of june 2002. At the present the
understanding of the detector performances is rather high so many analysis are
already underway.


title: Inclusive eta' Production from the Upsilon(1S)

abstract:
  Using the CLEO II detector at CESR, we measure the eta' - gluon - gluon
form-factor in Y(1S) decays. This form-factor especially at large eta' energies
may provide an explanation of the large rate for B -> Xs eta'. Our data do not
support a large anomalous coupling at higher q^2 and thus the large eta' rate
remains a mystery, possibly requiring a non-Standard Model explanation.


title: Atmospheric neutrino oscillations with MACRO

abstract:
  We present the latest results on the study of atmospheric neutrino
oscillations with the MACRO detector at Gran Sasso. Two sub-samples of events
have been analysed, both in terms of absolute flux and zenith angle
distribution: high energy events (with <E>~50 GeV) and low energy events (with
<E>~4 GeV). The high energy sample has been used also to check the nu_mu <->
nu_sterile oscillation hypothesis and to estimate neutrino energies using
Multiple Coulomb Scattering informations. All these analyses are mutually
consistent and strongly favour the nu_mu <-> nu_tau oscillation hypothesis with
maximal mixing and Delta_m^2 = 2.5 10^-3 eV^2.


title: Measurements of High Density Matter at RHIC

abstract:
  QCD predicts a phase transition between hadronic matter and a Quark Gluon
Plasma at high energy density. The Relativistic Heavy Ion Collider (RHIC) at
Brookhaven National Laboratory is a new facility dedicated to the experimental
study of matter under extreme conditions. I will discuss the first round of
experimental results from colliding heavy nuclei at RHIC and our current
understanding of the state of matter generated in such collisions,
concentrating on partonic energy loss and jet quenching as a probe of the
medium.


title: Measurement of muon induced neutron background at shallow sites

abstract:
  Cosmic muon induced neutrons are a major source of background for low
countrate experiments like neutrino oscillation or dark matter searches.
Especially at shallow sites these neutrons are the limiting factor for the
ultimate sensitivity of the measurement. Measurements of the neutron rate and
counter measures including active veto and passive shielding of the detector
are discussed for two neutrino oscillation experiments at shallow sites: the
KARMEN accelerator based experiment at RAL and the PALO VERDE reactor
experiment.


title: J-\psi Production via \chi_c Decays in 920 GeV pA Interactions

abstract:
  Using data collected by the HERA-B experiment, we have measured the fraction
of J\psi's produced via radiative chi_c decays in interactions of 920 GeV
protons with carbon and titanium targets. We obtained R_{\chi_c} = 0.32 \pm
0.06_{stat} \pm 0.04_{sys} for the fraction of J\psi from chi_c decays averaged
over proton-carbon and proton-titanium collisions. This result is in agreement
with previous measurements and is compared with theoretical predictions.


title: News from the Muon (g-2) Experiment at BNL

abstract:
  The magnetic moment anomaly a_mu = (g_mu - 2) / 2 of the positive muon has
been measured at the Brookhaven Alternating Gradient Synchrotron with an
uncertainty of 0.7 ppm. The new result, based on data taken in 2000, agrees
well with previous measurements. Standard Model evaluations currently differ
from the experimental result by 1.6 to 3.0 standard deviations.


title: Astroparticle Physics

abstract:
  The main issues in non-accelerator astroparticle physics are reviewed and
discussed. A short description is given of the experimental methods, of many
experiments and of their experimental results.


title:
Studies of Fragmentation Functions using e+e- Annihilation Data from
  PETRA and LEP

abstract:
  We present studies of the angular and momentum distributions of charged
particles in hadronic final states of e+e- annihilation. Some results are
derived from reanalysis of data of the JADE experiment operating at the PETRA
e+e- collider at DESY from 1979 to 1986 while other data are from OPAL.


title: Decay-mode independent searches for new scalar bosons with OPAL

abstract:
  Topological searches for neutral scalar bosons S0 produced in association
with a Z0 boson via the Bjorken process e+e- to SZ at centre-of-mass energies
of 91GeV and 183-209GeV are described. These searches are based on studies of
the recoil mass spectrum of Z to electrons or muons, and on a search for SZ
with Z to neutrinos and S to e+e- or photons. They cover the decays of the S
into an arbitrary combination of hadrons, leptons, photons and invisible
particles as well as the possibility that it might be stable. No indication for
a signal is found in the data and upper limits on the cross section of the
Bjorken process are calculated. Cross-section limits are given in terms of a
scale factor k with respect to the SM cross section for the Higgs-strahlung
process e+e- to HZ. These results can be interpreted in general scenarios
independently of the decay modes of the S. The examples considered here are the
production of a single new scalar particle with a decay width smaller than the
detector mass resolution, and for the first time, two scenarios with continuous
mass distributions, due to a single very broad state or several states close in
mass.


title: Electroweak Prospects for Tevatron RunII

abstract:
  The prospects of precision electroweak measurements from CDF and D0, using
RunII data, is reviewed.


title: BooNE Has Begun

abstract:
  E898, the MiniBooNE experiment at Fermi National Accelerator Laboratory, has
begun data collection. The experiment will test the neutrino oscillation signal
reported by the Liquid Scintillator Neutrino Detector at Los Alamos National
Laboratory. Data collection began in late August 2002.


title: Measurement of event shapes in deep inelastic scattering at HERA

abstract:
  Inclusive event-shape variables have been measured in the current region of
the Breit frame for neutral current deep inelastic ep scattering using an
integrated luminosity of 45.0 pb^-1 collected with the ZEUS detector at HERA.
The variables studied included thrust, jet broadening and invariant jet mass.
The kinematic range covered was 10 < Q^2 < 20,480 GeV^2 and 6.10^-4 < x < 0.6,
where Q^2 is the virtuality of the exchanged boson and x is the Bjorken
variable. The Q dependence of the shape variables has been used in conjunction
with NLO perturbative calculations and the Dokshitzer-Webber non-perturbative
corrections (`power corrections') to investigate the validity of this approach.


title: The Discovery of Neutrino Masses

abstract:
  The recent observation of neutrino oscillations with atmospheric and solar
neutrinos, implying that neutrinos are not massless, is a discovery of
paramount importance for particle physics and particle astrophysics. This
invited lecture discusses - hopefully in a way understandable also for the
non-expert - the physics background and the results mainly from the two most
relevant experiments, Super-Kamiokande and SNO. It also addresses the
implications for possible neutrino mass spectra. We restrict the discussion to
three neutrino flavours (nu_e, nu_mu, nu_tau), not mentioning a possible
sterile neutrino.


title: Neutrino Factory R&D - a global perspective

abstract:
  The current world status of plans for future particle-physics accelerators
and accelerator research and development is outlined. The developments for a
neutrino factory are placed in this context. Finally, a specific initiative
relevant for Europe is discussed.


title: Recent results from e+ e- --> hadrons

abstract:
  New results on the low energy e+ e- annihilation into hadrons from
Novosibirsk and Beijing are described. Implications of the new measurements for
the evaluation of the hadronic contribution to the muon anomalous magnetic
moment are discussed.


title: Precision Measurement of the Anomalous Magnetic Moment of the Muon

abstract:
  The muon g-2 experiment at Brookhaven National Laboratory measures the
anomalous magnetic moment of the muon, $a_\mu$, very precisely. This
measurement tests the Standard Model. The analysis for the data collected in
2000 (a $\mu^+$ run) is completed and the accuracy on $a_\mu$ is improved to
0.7 ppm, including statistical and systematic errors. The data analysis was
performed blindly between the precession frequency and the field analysis
groups in order to prevent a possible bias in the $a_\mu$ result. The result is
$a_{\mu}({\rm exp}) = 11~659~204(7)(5) \times 10^{-10}$ (0.7 ppm). This paper
features a detailed description of one of the four analyses and an update of
the theory.


title: Bd mixing measurements with the BABAR detector

abstract:
  The $B^0\bar{B^0}$ oscillation frequency $\Delta m_d$ has been measured with
the BaBar detector at the PEP-II asymmetric $B$ factory with different
experimental techniques. The discussion here is focused on the recent
simultaneous measurement of $\Delta m_d$ and $\tau_{B^0}$ with exclusively
reconstructed $B^0 \to D^{*-}l^+\nu_l$ decays, based on 23 million $B\bar{B}$
pairs collected by BaBar. The measurements of $\Delta m_d$ with fully
reconstructed hadronic decays and with dilepton events are also reviewed. The
average BaBar result is $\Delta m_d = 0.500 \pm 0.008 \pm 0.006$ $ps^{-1}$.


title:
Transmission and reflection of Gaussian beams by anisotropic parallel
  plates

abstract:
  Explicit and compact expressions describing the reflection and the
transmission of a Gaussian beam by anisotropic parallel plates are given.
Multiple reflections inside the plate are taken into account as well as
arbitrary optical axis orientation and angle of incidence.


title:
Measurement of Branching Fractions and Charge Asymmetries for Two-Body B
  Meson Decays with Charmonium

abstract:
  We report branching fractions and charge asymmetries for exclusive decays of
charged and neutral B mesons to two-body final states containing a charmonium
meson, J/psi or psi(2S). This result is based on a 29.4 fb^{-1} data sample
collected at the Upsilon(4S) resonance with the Belle detector at the KEKB
asymmetric e+e- collider.


title:
Search for Particles and Forces Beyond the Standard Model at HERA ep and
  Tevatron p\bar{p} Colliders

abstract:
  A review of searches for physics beyond the Standard Model carried out at
high energy lepton-hadron and hadron-hadron facilities is presented, with
emphasis on topics of interest for future data taking at the upgraded Tevatron
$p{\bar p}$ and HERA $ep$ colliders. The status and discovery prospects are
discussed for leptoquarks, Technicolour and supersymmetry, forbidden lepton and
quark flavour-changing processes, extra gauge bosons, excited states of
composite fermions, generic contact interactions and extra compactified
dimensions.


title: Further search for T-violation in the decay K^+ --> pi^0 mu^+ nu

abstract:
  A new result for the transverse mu^+ polarization, P_T, in the decay K^+ -->
pi^0 mu^+ nu has been obtained in the KEK E246 experiment. Combined with our
earlier result, P_T = (-1.12 +- 2.17(stat) +- 0.90(syst))x10^{-3} and Im(\xi) =
(-0.28 +- 0.69(stat) +- 0.30(syst))x10^{-2}, which are consistent with no
T-violation.


title: Status of the ANAIS experiment at Canfranc

abstract:
  The present status of the ANAIS experiment (Annual Modulation with NaI's) is
shown. ANAIS is intended to use more than 100 kg of NaI(Tl) in the Canfranc
Underground Laboratory (Spain) searching for seasonal modulation effects in the
WIMP signal; in a first stage, a prototype (one single 10.7 kg crystal) has
been developed in order to obtain the best conditions regarding the energy
threshold and the radioactive background in the low energy region as well as to
check the stability of the environmental conditions. The first results
corresponding to an exposure of 2069.85 kg day show an average background level
of 1.2 counts/(keV kg day) from threshold ($E_{thr} \sim 4$ keV, even using one
single photomultiplier) up to 10 keV.


title: Proton Structure Function Measurements from HERA

abstract:
  Measurements of proton structure functions made in neutral and charged
current interactions at HERA are discussed, covering four-momentum transfers
Q^2 from about 0.5 GeV^2 to 30000 GeV^2. The results include the rise of the
structure function F2 towards small x and electro-weak effects at high Q^2. QCD
fits made by the H1 and ZEUS collaborations provide both, parton densities with
uncertainties, and precise alpha_s determinations.


title: Readout Electronics for the CALICE ECAL and Tile HCAL

abstract:
  The aims of the CALICE test beam program are presented. The proposed
electronics readout system for the CALICE ECAL is described. It is a
purpose-built VME-based, unbuffered system.


title:
A Study of the Rare Decays $B^0\to D_s^{(*)+} \pi^-$ and $B^0\to
  D_s^{(*)-} K^+$

abstract:
  We report evidence for the decays $B^0\to D_s^{+} \pi^-$ and $B^0\to D_s^{-}
K^+$ and the results of a search for $B^0 \to D_s^{*+} \pi^-$ and $B^0\to
D_s^{*-} K^+$ in a sample of 84 milion Y(4S) decays into $B\bar{B}$ pairs
collected with the BaBar detector at the PEP II asymmetric-energy $e^{+}e^{-}$
storage ring. We measure the branching fraction Br($B^0 \to D_s^{+} \pi^-) =
3.2 \pm 0.9 ({\rm stat.})\pm 1.0 ({\rm syst.})$. and Br($B^0 \to D_s^{+} \pi^-)
= 3.2 \pm 1.0 ({\rm stat.})\pm 1.0 ({\rm syst.})$. We also set 90% C.L. limits
BR($B^0 \to D_s^{*+} \pi^-) < 4.1\times 10^{-5}$ at 90% C.L and BR($B^0 \to
D_s^{*-} K^+)< 2.5\times 10^{-5}$ at 90% C.L.


title: Tau physics at LEP

abstract:
  This paper gives an overview of some of the more interesting results obtained
at LEP in tau physics: precision measurements in neutral and charged currents
universality and structure, tau mass, topological and exclusive Branching
Ratios.


title: Beam Halo Monitoring at CDF

abstract:
  Losses from the proton and antiproton beams of the Fermilab Tevatron have
been shown to produce a halo which contribute to backgrounds to physics signals
in the Collider Detector at Fermilab (CDF). To provide a measure of the beam
halo and losses, we have installed arrays of scintillation counters on both
sides of the CDF detector. We describe here the physical configuration of these
counters, their implementation and performance within the Fermilab Accelerator
Control Network (ACNET). We show correlations between these new devices and the
accelerator operating conditions. We point out that the use of these monitors
is leading to improvement in the accelerator operations and reduced backgrounds
in CDF.


title: Study of Hadronic Five-Body Decays of Charmed Mesons

abstract:
  We study the decay of D+ and Ds+ mesons into charged five body final states,
and report the discovery of the decay mode D+ -> K+K-Pi+Pi+Pi-, as well as
measurements of the decay modes D+ -> K-Pi+Pi+Pi+Pi-, Ds+ -> K+K-Pi+Pi+Pi-, Ds+
-> PhiPi+Pi+Pi- and D+/Ds+ -> Pi+Pi+Pi+Pi-Pi-. An analysis of the resonant
substructure is also included, with evidence suggesting that both decays
proceed primarily through an a1 vector resonance.


title: Measurement of Branching Fractions in Tau Decays

abstract:
  Full LEP-I data collected by the ALEPH detector during 1991-1995 running are
analyzed in order to measure the $\tau$ decay branching fractions. The analysis
follows the global method used in the published study based on 1991-1993 data,
with several improvements, especially concerning the treatment of photons and
$\pi^0$'s. Extensive systematic studies are performed, in order to match the
large statistics of the data sample corresponding to 327148 measured and
identified $\tau$ decays. Preliminary values for the branching fractions are
obtained for the 2 leptonic channels and 11 hadronic channels defined by their
respective numbers of charged particles and $\pi^0$'s. Using previously
published ALEPH results on final states with charged and neutral kaons,
corrections are applied so that branching ratios for exclusive final states
without kaons are derived. Some physics implications of the results are given,
in particular concerning universality in the leptonic charged weak current,
isospin invariance in $a_1$ decays, and the separation of vector and
axial-vector components of the total hadronic rate.


title: Higgs Statistics for Pedestrians

abstract:
  We review the results of the Standard Model Higgs boson search at LEP. An
emphasis is put on revealing the details behind the statistical procedure
developed by the LEP Higgs working group. The procedure is explained using a
toy model which allows the reader to estimate the significance of the
experimental observation which led at the time to a scientific debate on
whether LEP has observed a 115 GeV Higgs boson.


title: Recent Results from the K2K Experiment

abstract:
  The K2K experiment has collected approximately half of its allocated protons
on target between June of 1999 and July of 2001. These proceedings give a short
introduction to the experiment and summarize some of the recent results.


title: Probing extra spacetime dimensions at the Tevatron

abstract:
  Theories with extra spacetime dimensions aiming at resolving the hierarchy
problem have recently been developed. These scenarios have provided exciting
new grounds for experimental probes. A review of the searches conducted at the
Tevatron in this framework during its first running phase and the prospects for
its second running phase are reviewed.


title: Results from CDF and D0 (Everything but the B)

abstract:
  With the start of Run II at the Fermilab Tevatron a host of new physics
opportunities are opened. In this paper we will review the prospects for
physics at the CDF and \Dzero experiments. Topics ranging from QCD, to
electro-weak precision measurements, to top-quark physics, to searches for the
Higgs boson and signals of physics beyond the Standard Model will be discussed.
B-Physics at the Tevatron is covered in a separate contribution to these
proceedings. We will outline how upgrades to the accelerator and the detectors
make these studies possible with precisions higher than ever achieved
previously and will show results from the first data collected in Run II. These
results give us confidence in our ability to achieve ambitious physics goals,
and point the way toward a bright future for the Tevatron.


title: Prospects of Higgs Physics at the LHC

abstract:
  The search for the Higgs boson is a major physics goal of the future Large
Hadron Collider. The discovery potential is described as a function of the
Higgs mass. It is shown that a Standard Model Higgs boson can be discovered
within the first year of data taking. The status of MSSM Higgs searches is also
discussed.


title: Jet Physics at HERA

abstract:
  Analyses of jet production at HERA have become precise enough to perform QCD
studies which are both competitive and complementary to those at e+e- and
p-pbar colliders. This report summarises some of the latest results on jet
physics from the H1 and ZEUS Collaborations.


title:
Search for Long-lived Charged Massive Particles in anti-p p Collisions
  at s**1/2 = 1.8 TeV

abstract:
  We report a search for production of long-lived charged massive particles in
a data sample of 90 pb^{-1} of \sqrt{s} = 1.8 TeV p anti-p collisions recorded
by the Collider Detector at Fermilab (CDF). The search uses the muon-like
penetration and anomalously high ionization energy loss signature expected for
such a particle to discriminate it from backgrounds. The data is found to agree
with background expectations, and cross section limits of \cal{O} (1) pb are
derived using two reference models, a stable quark and a stable scalar lepton.


title:
Measurement of the $B^0 -\bar{B}^0$ mixing rate with $B^0(\bar{B}^0) \to
  D^{*\mp} \pi^{\pm}$ partial reconstruction

abstract:
  We report a measurement of the $B^0-\bar{B}^0$ mixing parameter $\Delta m_d$
based on a $\rm 29.1~fb^{-1}$ sample of $\Upsilon (4S)$ resonance decays
collected by the Belle detector at the KEKB asymmetric $e^+ e^-$ collider. We
use events with a partially reconstructed $B^0(\bar{B}^0) \to D^{*\mp}
\pi^{\pm}$ candidate and where the flavor of the accompanying $B$ meson is
identified by the charge of the lepton from a $B^0(\bar{B}^0) \to X^{\mp}
\ell^{\pm} \nu$ decay. The proper-time difference between the two $B$ mesons is
determined from the distance between the two decay vertices. From a
simultaneous fit to the proper-time distributions for the same-flavor
($B^0(\bar{B}^0)$, $\ell^{\pm}$) and opposite-flavor ($B^0(\bar{B}^0)$,
$\ell^{\mp}$) event samples, we measure the mass difference between the two
mass eigenstates of the neutral $B$ meson to be $\Delta m_d$= $(0.509 \pm
0.017~(\rm stat) \pm 0.020~(\rm syst))~ps^{-1}$.


title: A Measurement of the tau -> mu nu nu Branching Ratio

abstract:
  The tau -> mu nu nu branching ratio has been measured using data collected
from 1990 to 1995 by the OPAL detector at the LEP collider. The resulting value
of B(tau -> mu nu nu) = 0.1734 +- 0.0009(stat) +- 0.0006(syst) has been used in
conjunction with other OPAL measurements to test lepton universality, yielding
the coupling constant ratios gmu/ge=1.0005+-0.0044 and gt/ge=1.0031+-0.0048, in
good agreement with the Standard Model prediction of unity. A value for the
Michel parameter eta = 0.004 +- 0.037 has also been determined and used to find
a limit for the mass of the charged Higgs boson mH+- > 1.25 tan beta, in the
Minimal Supersymmetric Standard Model.


title: Measurement of the Muon (g-2)-Value

abstract:
  The muon (g-2) experiment is described, and the recent results are presented.
These results represent the final measurement for the positive muon.


title: Analyzing Powers for Forward p+p->pi0+X at STAR

abstract:
  Preliminary results of the analyzing power for the production of forward,
high-energy pi0 mesons from collisions of transversely polarized protons at
sqrt(s)=200 GeV from STAR are presented. The kinematic ranges covered by the
data are x_F=0.2-0.6 and p_T=1-3 GeV/c. The analyzing power at sqrt(s)=200 GeV
is found to be comparable to that observed at sqrt(s)=20 GeV.


title: Jet Production in CDF

abstract:
  A review of some of the most important QCD results from Run 1 is presented,
together with first preliminary Run 2 measurements (based on the very first
data collected by the experiment) and future prospects as the integrated
luminosity increases.


title:
The Kr2Det project: Search for mass-3 state contribution |U_{e3}|^2 to
  the electron neutrino using a one reactor - two detector oscillation
  experiment at Krasnoyarsk underground site

abstract:
  The main physical goal of the project is to search with reactor antineutrinos
for small mixing angle oscillations in the atmospheric mass parameter region
around {\Delta}m^{2}_{atm} ~ 2.5 10^{-3} eV^2 in order to find the element
U_{e3} of the neutrino mixing matrix or to set a new more stringent constraint
(U_{e3} is the contribution of mass-3 state to the electron neutrino flavor
state). To achieve this we propose a "one reactor - two detector" experiment:
two identical antineutrino spectrometers with $\sim$50 ton liquid scintillator
targets located at ~100 m and ~1000 m from the Krasnoyarsk underground reactor
(~600 mwe). In no-oscillation case ratio of measured positron spectra of the
\bar{{\nu}_e} + p \to e^{+} + n reaction is energy independent. Deviation from
a constant value of this ratio is the oscillation signature. In this scheme
results do not depend on the exact knowledge of the reactor power, nu_e
spectra, burn up effects, target volumes and, which is important, the
backgrounds can periodically be measured during reactor OFF periods. In this
letter we present the Krasnoyarsk reactor site, give a schematic description of
the detectors, calculate the neutrino detection rates and estimate the
backgrounds. We also outline the detector monitoring and calibration
procedures, which are of a key importance. We hope that systematic
uncertainties will not accede 0.5% and the sensitivity U^{2}_{e3} ~4 10^{-3}
(at {\Delta}m^{2} = 2.5 10^{-3} eV^2) can be achieved.


title: A Calorimetric Search on Double Beta Decay of 130Te

abstract:
  We report on the final results of a series of experiments on double decay of
130Te carried out with an array of twenty cryogenic detectors. The set-up is
made with crystals of TeO2 with a total mass of 6.8 kg, the largest operating
one for a cryogenic experiment. Four crystals are made with isotopically
enriched materials: two in 128Te and two others in 130Te. The remaining ones
are made with natural tellurium, which contains 31.7 % and 33.8 % 128Te and
130Te, respectively. The array was run under a heavy shield in the Gran Sasso
Underground Laboratory at a depth of about 3500 m.w.e. By recording the pulses
of each detector in anticoincidence with the others a lower limit of 2.1E23
years has been obtained at the 90 % C.L. on the lifetime for neutrinoless
double beta decay of 130Te. In terms of effective neutrino mass this is the
most restrictive limit in direct experiments, after those obtained with Ge
diodes. Limits on other lepton violating decays of 130Te and on the
neutrinoless double beta decay of 128Te to the ground state of 128Xe are also
reported and discussed. An indication is presented for the two neutrino double
beta decay of 130Te. Some consequences of the present results in the
interpretation of geochemical experiments are discussed.


title: Experimental approaches to low x at HERA

abstract:
  Data are presented on the production of jets and pi^0 mesons at low Bjorken x
in a kinematic region where standard DGLAP evolution in Q^2 gives little phase
space for high p_t particle and jet production.
  The data are compared with various QCD models based on different treatments
of parton emissions at small x.


title: Measuring the linear polarization of $\gamma$s in 20-170 GeV range

abstract:
  The Na59 collaboration aims to measure the linear polarization of its photon
beam in the 20-170 GeV range, using an aligned thin crystal. The tracks of
$e^-/e^+$ pairs created in two different crystal targets, germanium and
diamond, are reconstructed to obtain the photon spectrum. Using the
polarization dependence of the pair production cross section in an aligned
crystal, photon polarization is obtained to be 55% at the vicinity of 70 GeV.


title: Measurements of the Decay KL->e+e-mu+mu-

abstract:
  The KTeV experiment at Fermilab has isolated a total of 132 events from the
rare decay KL->e+e-mu+mu-, with an estimated background of 0.8 events. The
branching ratio of this mode is determined to be 2.69 +/- 0.24 (stat) +/- 0.12
(syst) x 10^-9, with a radiative cutoff of M(eemm)^2/M(K)^2 > 0.95. The first
measurement using this mode of the parameter alpha from the D'Ambrosio,
Isidori, and Portoles model of the KLg*g* vertex yields a result of -1.59 +/-
0.37, consistent with values obtained from other decay modes. Because of the
limited statistics, no sensitivity is found to the DIP parameter beta. The
magnitude of the angular distribution asymmetry between the e+e- and mu+mu-
planes, indicative of a CP-violating contribution to the decay, is found to be
consistent with zero. We set a 90% C.L. upper limit of 4.12 x 10^(-11) on the
branching ratio of the lepton flavor--violating mode KL->e+-e+-mu+-mu+-, a
factor of three improvement over the current limit from the KTeV experiment.

New Limits on Neutrino Magnetic Moments from the Kuo-Sheng Reactor
  Neutrino Experiment

abstract:
  A laboratory has been set up at the Kuo-Sheng Nuclear Power Station at a
distance of 28 m from the 2.9 GW reactor core to study low energy neutrino
physics. A detector threshold of 5 keV and a background level of 1
counts/day-keV-kg at 12-60 keV was achieved with a high purity germanium
detector of mass 1.06 kg surrounded by anti-Compton detectors with NaI(Tl) and
CsI(Tl) crystal scintillators. Using 4712 and 1250 hours of Reactor ON and OFF
data, respectively, limits of the neutrino magnetic moment of mu_nu < 1.3(1.0)
X 10^{-10} mu_B at 90(68)% confidence level were derived. Indirect bounds of
the nu_e_bar radiative lifetime of m_nu^3 * tau_nu > 2.8(4.8) X 10^{18} eV^3 s
can be inferred.


title:
Searches for Flavour Changing Neutral Currents and Lepton Flavour
  Violation at HERA

abstract:
  A summary of the recent searches for anomalous single top-quark production
and lepton flavour violation in high energy ep collisions is presented. Single
top-quark production via an anomalous flavour changing neutral current
gamma-u-t coupling would lead to the reaction ep->etX, t->Wb. H1 observed an
excess of events above the Standard Model prediction in the leptonic decay
channel of the W boson, leading to an isolated lepton, large missing transverse
momentum and a jet with large transverse momentum. Five of these events are
compatible with single top-quark production, compared to 1.8 events expected
from background processes. ZEUS observed no excess above the SM background
expectation in the leptonic channel. Neither of the two experiments found a
deviation from the SM background expectation in the 3-jet final state, which
would result from the hadronic decay of the W boson. Searches for lepton
flavour violating interactions of the type ep->mu X and ep->tau X have been
performed. No evidence was found for lepton flavour violation and limits were
derived on the production of leptoquarks and R_p violating squarks, which could
mediate such interactions.

title:
Charged hadron transverse momentum distributions in Au+Au collisions at
  sqrt(s_NN) = 200 GeV

abstract:
  We present transverse momentum distributions of charged hadrons produced in
Au+Au collisions at sqrt(s_NN) = 200 GeV. The evolution of the spectra for
transverse momenta p_T from 0.25 to 5GeV/c is studied as a function of
collision centrality over a range from 65 to 344 participating nucleons. We
find a significant change of the spectral shape between proton-antiproton and
peripheral Au+Au collisions. Comparing peripheral to central Au+Au collisions,
we find that the yields at the highest p_T exhibit approximate scaling with the
number of participating nucleons, rather than scaling with the number of binary
collisions.


title: Indications of Neutrino Oscillation in a 250 km Long-baseline Experiment

abstract:
  The K2K experiment observes indications of neutrino oscillation: a reduction
of $\nu_\mu$ flux together with a distortion of the energy spectrum. Fifty-six
beam neutrino events are observed in Super-Kamiokande (SK), 250 km from the
neutrino production point, with an expectation of $80.1^{+6.2}_{-5.4}$.
Twenty-nine one ring $\mu$-like events are used to reconstruct the neutrino
energy spectrum, which is better matched to the expected spectrum with neutrino
oscillation than without. The probability that the observed flux at SK is
explained by statistical fluctuation without neutrino oscillation is less than
1%.
