title: Experimental measurement of muon (g-2)

abstract:
  The muon (g-2) experiment at Brookhaven National Laboratory has measured the
anomalous magnetic moment of the positive muon with a precision of 0.7 ppm.
This paper presents that result, concentrating on some of the important
experimental issues that arise in extracting the anomalous precession frequency
from the data.


title: Challenging the challenge: handling data in the Gigabit/s range

abstract:
  The ALICE experiment at CERN will propose unprecedented requirements for
event building and data recording. New technologies will be adopted as well as
ad-hoc frameworks, from the acquisition of experimental data up to the transfer
onto permanent media and its later access. These issues justify a careful,
in-depth planning and preparation. The ALICE Data Challenge is a very important
step of this development process where simulated detector data is moved from
dummy data sources up to the recording media using processing elements and
data-paths as realistic as possible. We will review herein the current status
of past, present and future ALICE Data Challenges, with particular reference to
the sessions held in 2002 when - for the first time - streams worth one week of
ALICE data were recorded onto tape media at sustained rates exceeding 300 MB/s.


title: Recent CLEO Upsilon(1S) and Upsilon(3S) Results

abstract:
  Recent CLEO results on the observation of the $\Upsilon(1D)$ state and a
search for the $\eta_b(1S)$ state from a data sample of $4.7 \times
10^6\,\Upsilon(3S)$ decays collected with the CLEO-III detector, and a
measurement of the $\eta^{\prime}$ production spectrum using $1.9 \times
10^6\,\Upsilon(1S)$ decays collected with the CLEO-II detector are described.


title: New Results from the FOCUS/E831 Experiment

abstract:
  The E831/FOCUS experiment at Fermilab is a photoproduction experiment which
generated high quality charm particles. During its run, we obtained a large
data set, including more than 1 million charm mesons in the Kpi/K2pi/K3pi mode
decays. The current analysis efforts by the collaboration members are quite
active and diverse. I will summarize the recent papers published by the FOCUS
group on topics of semileptonic decays of charm mesons.


title: Level-1 Regional Calorimeter Trigger System for CMS

abstract:
  The Compact Muon Solenoid (CMS) calorimeter regional trigger system is
designed to detect signatures of isolated and non-isolated electrons/photons,
jets, ?-leptons, and missing and total transverse energy using a deadtimeless
pipelined architecture. This system contains 18 crates of custom-built
electronics. The pre-production prototype backplane, boards, links and
Application-Specific Integrated Circuits (ASICs) have been built and their
performance is characterized.


title:
Observation of a narrow, near-threshold enhancement in the p\bar{p} mass
  spectrum from radiative J/psi--> gamma p\bar{p} decays

abstract:
  We observe a narrow enhancement near 2m_p in the invariant mass spectrum of
p\bar{p} pairs from radiative J/psi-->gamma p\bar{p} decays. No similar
structure is seen in J/psi-->pi0 p\bar{p} decays. The results are based on an
analysis of a 58 million event sample of J/psi decays accumulated with the
BESII detector at the Beijing electron-positron collider. The enhancement can
be fit either with an S- or P-wave Breit Wigner resonance function; in the case
of the S-wave fit, the peak mass is below 2m_p at M=1859 +3 -10(stat) +5 -25
(syst) MeV/c**2 and the total width is Gamma < 30 MeV/c**2, at the 90%
confidence level. These mass and width values are not consistent with the
properties of any known resonance.


title:
Study of the process $e^+e^- \to \pi^+\pi^-\pi^0$ in the energy region
  $\sqrt[]{s}$ below 0.98 GeV

abstract:
  The cross section of the process $e^+e^-\to \pi^+\pi^-\pi^0$ was measured in
the Spherical Neutral Detector (SND) experiment at the VEPP-2M collider in the
energy region $\sqrt[]{s}$ below 980 MeV. This measurement was based on about
$1.2 \times 10^6$ selected events. The obtained cross section was analyzed
together with the SND and DM2 data in the energy region $\sqrt[]{s}$ up to 2
GeV. The $\omega$-meson parameters: $m_\omega=782.79\pm 0.08\pm 0.09$ MeV,
$\Gamma_\omega=8.68\pm 0.04\pm 0.15$ MeV and $\sigma(\omega\to 3\pi)=1615\pm
9\pm 57$ nb were obtained. It was found that the experimental data cannot be
described by a sum of only $\omega$, $\phi$, $\omega^\prime$ and
$\omega^{\prime\prime}$ resonances contributions. This can be interpreted as a
manifestation of $\rho\to 3\pi$ decay, suppressed by $G$-parity, with relative
probability $B(\rho\to 3\pi) = (1.01\pm^{0.54}_{0.36}\pm 0.034) \times
10^{-4}$.


title: Charm in electron proton collisions

abstract:
  Charm in electron proton collisions is a particularly large and interesting
field. For this summary two topics particularly relevant for HERA have been
selected. First the study of inelastic J/psi production in both the
photoproduction and the electroproduction regime, study still needed to clarify
the J\psi production mechanisms. Second the analysis of D* photoproduction
events, study than can lead to a better understanding of the photon structure.


title: Stop and sbottom searches at LEP

abstract:
  This talk reviews the searches for sbottom and stop quarks at LEP. The
existing results of the four LEP experiments for sbottom and stop quarks
searches are summarized. Furthermore, new mass limits on stable hadronizing
squarks and gluinos are derived by combining Z-lineshape constraints with
direct searches for squarks and gluinos using ALEPH data. All limits are
derived in the framework of R-parity conserving models.


title: Vector Meson Production at HERA

abstract:
  At the HERA collider the experiments H1 and ZEUS have studied the exclusive
production of vector mesons over a wide kinematical range. A selection of
recent measurements of the cross sections has been presented at Moriond QCD
2003.


title:
Search for pair-produced leptoquarks in e+e- interactions at sqrt(s) =
  189 - 209 GeV

abstract:
  A search for pair-produced leptoquarks is performed using e+e- collision
events collected by the OPAL detector at LEP at centre-of-mass energies between
189 and 209 GeV. The data sample corresponds to a total integrated luminosity
of 596 pb^-1. The leptoquarks are assumed to be produced via couplings to the
photon and the Z0. For a given search channel only leptoquark decays involving
a single lepton generation are considered. No evidence for leptoquark pair
production is observed. Lower limits on masses for scalar and vector
leptoquarks are calculated. The results improve most of the LEP limits derived
from previous searches for the pair production process by 10-25 GeV, depending
on the leptoquark quantum numbers.


title: Charm Physics at the Tevatron

abstract:
  First charm physics results from the CDF and D0 experiments at the Tevatron
Run II are presented. With the addition of the Secondary Vertex Trigger CDF has
become a competitive charm experiment.


title: CP Violation: Recent Results from BABAR

abstract:
  We review recent time-dependent measurements in the B meson sector based on
data collected between 1999 and 2002 by the BABAR detector, which correspond to
approximately 88 million BB pairs.


title: Selected Results in Hadronic Final State Physics at HERA

abstract:
  This presentation reports recent results from the hadronic final state in DIS
at HERA. Forward jet and $\pi^0$ production have been measured by the H1
experiment. The forward jet production cross section shows significant
deviation from the predictions based on DGLAP evolution. The forward $\pi^0$
data discriminate between different QCD models and are best described by models
which take into account the partonic substructure of virtual photons. Inclusive
$K_s^0K_s^0$ production in $ep$ has been studied with the ZEUS detector using
an integrated luminosity of 120 pb$^{-1}$. Two states are observed at masses of
1537 MeV and 1726 MeV as well as an enhancement around 1300 MeV. The state at
1537 MeV is consistent with the well established $f_2^\prime(1525)$. The state
at 1726 MeV may be the glueball candidate $f_0(1710)$.


title:
The new limit for the magnetic moment of the electron antineutrino from
  the MUNU experiment

abstract:
  The MUNU experiment uses the electron antineutrino-electron elastic
scattering to examine the magnetic properties of the electron antineutrino. The
detector is situated at 18 m from the reactor, serving as an electron
antineutrino source. Data corresponding to 66.6 days reactor-on and 16.7 days
reactor-off are reported in this study .The electron recoil spectrum is
obtained, using the visual scanning procedure. A new limit on the neutrino
magnetic moment is derived.


title: SUSY Searches at LEP

abstract:
  Between 1995-2000, the LEP e+e- collider has been operated above the Z0 peak,
at centre-of-mass energies sqrt(s) = 130-209 GeV. Searches for supersymmetric
particles have been performed using these data samples. The results from the
four LEP experiments have been combined. Model independent limits on the
pair-production cross-sections of supersymmetric particles and constraints on
their masses are presented in the context of the Minimal Supersymmetric
Standard Model (MSSM) and in the context of gauge-mediated supersymmetry
breaking models (GMSB). Results assuming an R-parity violating scenario are
also reviewed.


title: New Results on Kaon Decays from NA48

abstract:
  New measurements of K_L and K_S decays from the NA48 experiment are
presented. From data taken in the year 2001, the value of the K_e3 charge
asymmetry has been determined to delta_L(e) = (3.317 +- 0.070(stat) +- 0.072
(syst)) x 10^-3. From a special high-intensity K_S run period performed in
2000, NA48 has found a limit of 1.4 x 10^-6 on the K_S -> 3 pi0 branching ratio
and measured the parameter eta_000. The same data sample also leads to the
first observation of the rare decay K_S -> pi0 gamma gamma. All results are
still preliminary.


title: Measurement of Baryonic B Decays

abstract:
  Recent results of baryonic B decays from Belle are reported. This study is
done by a 78 fb$^{-1}$ data sample, consisting of $85.0 \pm 0.5$ million
$B\bar{B}$ pairs, collected by the Belle detector at the KEKB asymmetric energy
$e^+e^-$ (3.5 on 8 GeV) collider. The results reported here include the first
observation of the two-body decay $B^0 \to p\bar\Lambda_c$, the first hyperonic
decay $B^0 \to p\bar{\Lambda}\pi^-$, and first observations of $B^+ \to
p\bar{p}\pi^+$, $B^0 \to p\bar{p}K_S^0$, and $B^+ \to p\bar{p}K^{\star +}$.


title: W mass at LEP2

abstract:
  Recent studies to finalize the systematic error estimates on the measurement
of the mass of the W boson at LEP2 are reviewed. Results including a new
preliminary value from Aleph are updated together with the world average which
is now 80.426 +- 0.034GeV/c2. The updated electroweak fit gives a 95% C.L.
upper limit on the mass of the Higgs boson of 211GeV/c2.


title: B Physics at D0

abstract:
  The DO detector at FNAL has undergone a significant upgrade for its present
Run II data taking period, allowing for a broad B physics programme. This
report focuses on studies performed on a sample of approximately 75 thousand
inclusive J/psi events. Preliminary results on mass and lifetime measurements
and prospects for flavour tagging are presented.


title: Rapidity gaps in gluon jets / color reconnection at LEP

abstract:
  Gluon jets with a large gap in the rapidity distribution of particles within
the jet are very sensitive to color reconnection effects. Gluon jets of this
type, selected from hadronic Z0 decay events produced in e+e- annihilations at
LEP, are used to test three QCD models which include a simulation of color
reconnection: one in the Ariadne Monte Carlo, one in the
  Herwig Monte Carlo, and the other by Rathsman in the Pythia Monte Carlo. We
conclude that color reconnection as implemented by the Rathsman and Ariadne
models is disfavored. We don't obtain a definite conclusion concerning the
Herwig color reconnection model.


title: Statistical Challenges with Massive Data Sets in Particle Physics

abstract:
  The massive data sets from today's particle physics experiments present a
variety of challenges amenable to the tools developed by the statistics
community. From the real-time decision of what subset of data to record on
permanent storage, to the reduction of millions of channels of electronics to a
few dozen high-level variables of primary interest, to the interpretation of
these high-level observables in the context of an underlying physical theory,
there are many problems that could benefit from a higher-bandwidth exchange of
ideas between our fields. Examples of interesting problems from various stages
in the collection and interpretation of particle physics data are provided in
an attempt to whet the appetite of future collaborators with knowledge of
potentially helpful techniques, and to encourage fruitful discussion between
the particle physics and statistics communities.


title: Quaero: Motivation, Summary, Status

abstract:
  Quaero is a web-based tool that automates high-pT analyses. It has been
designed with the goals of expunging exclusion contours from conference talks,
obviating the necessity of "uncorrecting" experimental results, reducing human
bias in experimental measurements, reducing by orders of magnitude the time
required to perform analyses, allowing the publication of collider data in
their full dimensionality, rigorously propagating systematic errors,
dramatically increasing the robustness of experimental results, and
facilitating the combination of results among different experiments. Quaero has
been used to make a subset of D0 Run I data publicly available, and is being
explored as a means of putting LEP data at your fingertips. These proceedings
review the motivation for Quaero, summarize the key enabling ideas, and provide
a snapshot of the project's present status.


title: Top quark production cross-section at the Tevatron Run 2

abstract:
  The top quark pair production cross-section ${\sigma}_{t\bar{t}}$ has been
measured in $p\bar{p}$ collisions at center of mass energies of 1.96 TeV using
Tevatron Run 2 data. In the begining of Run 2 both CDF and D\O\
$\sigma_{t\bar{t}}$ measurements in the {\it dilepton} channel
$t\bar{t}{\to}WbW\bar{b}{\to}\bar{\ell}{\nu}_{\ell}b{\ell}^{'}\
bar{\nu}_{{\ell}^{'}}\bar{b}$ and in the {\it lepton plus jets} channel
$t\bar{t}{\to}WbW\bar{b}{\to}q\bar{q}^{'}b{\ell}\bar{\nu}_{\ell
}\bar{b}+\bar{\ell}{\nu}_{\ell}bq\bar{q}^{'}\bar{b}$ agree with the NLO
(Next-to-Leading-Order) theoretical predictions. The presence of a top signal
in Tevatron data has been reestablished.


title: The CERN Detector Safety System for the LHC Experiments

abstract:
  The Detector Safety System (DSS), currently being developed at CERN under the
auspices of the Joint Controls Project (JCOP), will be responsible for assuring
the protection of equipment for the four LHC experiments. Thus, the DSS will
require a high degree of both availability and reliability. After evaluation of
various possible solutions, a prototype is being built based on a redundant
Siemens PLC front-end, to which the safety-critical part of the DSS task is
delegated. This is then supervised by a PVSS SCADA system via an OPC server.
The PLC front-end is capable of running autonomously and of automatically
taking predefined protective actions whenever required. The supervisory layer
provides the operator with a status display and with limited online
reconfiguration capabilities. Configuration of the code running in the PLCs
will be completely data driven via the contents of a "Configuration Database".
Thus, the DSS can easily adapt to the different and constantly evolving
requirements of the LHC experiments during their construction, commissioning
and exploitation phases.


title: Observation of B -> phi phi K

abstract:
  We report the observation of the decay mode B -> phi phi K based on an
analysis of 78 fb^{-1} of data collected with the Belle detector at KEKB. This
is the first example of a b -> s sbar s sbar s transition. The branching
fraction for this decay is measured to be B(B^{+-} -> phi phi K^{+-}) = (2.6
^{+1.1}_{-0.9} +- 0.3) x 10^{-6} for a phi phi invariant mass below 2.85
GeV/c^2. Results for other related charmonium decay modes are also reported.


title: Hadronic B Decays at CLEO

abstract:
  I present highlights of recent CLEO results on the hadronic decay modes of
the B meson. Topics covered include two body rare B decays modes, a new
measurement of $(B^0 \to D^0 K^+) / (B^0 \to D^0 \pi^+)$, an in depth study of
the decay $B^0 \to D^* \rho$, as well as a preliminary search for charge
asymmetry in the decay $B^0 \to K^* \pi$.


title: A Very Fast Ramping Muon Synchrotron for a Neutrino Factory

abstract:
  A 4600 Hz fast ramping synchrotron is studied as an economical way of
accelerating muons from 4 to 20 GeV/c for a neutrino factory. Eddy current
losses are minimized by the low machine duty cycle plus thin grain oriented
silicon steel laminations and thin copper wires. Combined function magnets with
high gradients alternating within single magnets form the lattice. Muon
survival is 83%.


title:
Search for stable hadronizing squarks and gluinos in e+e- collisions up
  to sqrt(s) = 209 GeV

abstract:
  Searches for stable, hadronizing scalar quarks and gluinos are performed
using the data collected with the ALEPH detector at LEP. Gluon splitting into a
gluino or a squark pair is searched for at centre-of-mass energies around the Z
resonance, in the e+e- -> q qbar gluino gluino and q qbar squark antisquark
processes. Stable squark pair production, and stop pair production with
subsequent decays into a stable gluino, stop -> c gluino, are also directly
searched for at centre-of-mass energies from 183 to 209 GeV.
  Altogether, stable hadronizing stop (sbottom) quarks are excluded up to
masses of 95 (92) GeV/c2, and stable hadronizing gluinos are excluded up to
26.9 GeV/c2, at 95% confidence level. In the framework of R-parity-conserving
supersymmetric models in which the gluino and the stop quark are the two
lightest supersymmetric particles, a 95% C.L. lower limit of 80 GeV/c2 is set
on the stop quark mass.


title: First D0 Jet Measurements at sqrt{s}=1.96 TeV

abstract:
  We present the first Run II measurements with the DO detector of the
inclusive jet and dijet cross sections at sqrt{s}=1.96 TeV. This analysis is
based on an integrated luminosity of 34 pb-1. The results from a
next-to-leading order perturbative QCD calculation are compared to the measured
cross sections. The theoretical calculation agrees with the data.


title: Jet production in ep collisions

abstract:
  Results obtained by the H1 and ZEUS Collaborations on jet production in
photoproduction and deep-inelastic scattering are presented and compared to NLO
QCD models.


title: The AMS-02 Time of Flight System. Final Design

abstract:
  The AMS-02 detector is a superconducting magnetic spectrometer that will
operate on the International Space Station. The time of flight (TOF) system of
AMS-02 is composed by four scintillator planes with 8, 8, 10, 8 counters each,
read at both ends by a total of 144 phototubes. This paper describes the new
design, the expected performances, and shows preliminary results of the ion
beam test carried on at CERN on October 2002.


title:
Measurement of Isolated Prompt Photon Production in Photon-Photon
  Collisions at sqrt(s)_ee=183-209 GeV

abstract:
  For the first time at LEP the production of prompt photons is studied in the
collisions of quasi-real photons using the OPAL data taken at e+e-
centre-of-mass energies between 183 GeV and 209 GeV. The total inclusive
production cross-section for isolated prompt photons in the kinematic range of
photon transverse momentum larger than 3.0 GeV and absolute photon
pseudorapidity less than 1 is determined to be 0.32 +- 0.04 (stat) +- 0.04
(sys) pb. Differential cross-sections are compared to the predictions of a
next-to-leading-order (NLO) calculation.


title: Using XDAQ in Application Scenarios of the CMS Experiment

abstract:
  XDAQ is a generic data acquisition software environment that emerged from a
rich set of of use-cases encountered in the CMS experiment. They cover not the
deployment for multiple sub-detectors and the operation of different processing
and networking equipment as well as a distributed collaboration of users with
different needs. The use of the software in various application scenarios
demonstrated the viability of the approach. We discuss two applications, the
tracker local DAQ system for front-end commissioning and the muon chamber
validation system. The description is completed by a brief overview of XDAQ.


title:
OpenMosix approach to build scalable HPC farms with an easy management
  infrastructure

abstract:
  The OpenMosix approach is a good solution to build powerful and scalable
computing farms. Furthermore an easy management infrastructure is implemented
using diskless nodes and network boot procedures. In HENP environment, the
choice of OpenMosix has been proven to be an optimal solution to give a general
performance boost on implemented systems thanks to its load balancing and
process migration features. In this poster we give an overview of the
activities, carried out by our computing center, concerning the installation,
management, monitoring, and usage of HPC Linux clusters running OpenMosix.


title: Evaluating current processors performance and machines stability

abstract:
  Accurately estimate performance of currently available processors is becoming
a key activity, particularly in HENP environment, where high computing power is
crucial. This document describes the methods and programs, opensource or
freeware, used to benchmark processors, memory and disk subsystems and network
connection architectures. These tools are also useful to stress test new
machines, before their acquisition or before their introduction in a production
environment, where high uptimes are requested.


title:
Web portals, instant messaging and web communities: new tools for online
  collaboration

abstract:
  Web portals are nowadays very popular. This type of web sites let users to
share information, request advice or help in a particular field, and
furthermore allow them to create and extend sites content. Combined with
instant messaging systems, used to send messages or files instantaneously to a
user or a group of users, and with various kinds of chat programs, which
connect two or more individuals simulating a conversation, it is now possible
to create "web communities". In this paper we present the opensource tools used
to create the "Grid Support Community" of the National Institute for Nuclear
Physics in Italy.


title: |Vcb| and |Vub| from CLEO

abstract:
  I report on studies of inclusive and exclusive semileptonic b -> c l nu and b
-> u l nu decays in 9.7 million BBbar events accumulated with the CLEO detector
in symmetric e^+e^- collisions produced in the Cornell Electron Storage Ring
(CESR). Various experimental techniques, including the study of spectral
moments and the inference of neutrino candidates by exploiting the hermeticity
of the CLEO detector, are used in conjunction with theoretical calculations to
provide estimates of the CKM matrix elements |Vcb| and |Vub|.


title:
Object Database for Constants: The common CLEO Online and Offline
  solution

abstract:
  After the successful conclusion of the CLEO III phase, the CLEO experiment at
the Cornell Electron Positron Storage Ring CESR is preparing for its transition
to CLEO-c. This new program contains a wide array of Physics studies at e+ e-
collisions at center of mass energies between 3 GeV and 5 GeV that will provide
new insights into QCD. Because the existing Silicon Vertex Detector needed to
be replaced within a short time, a 6 layer vertex drift chamber has been
installed in spring 2003. At the same time, the existing Ring Imaging Cherenkov
Detector, along with a conventional drift chamber, E.M. calorimeter and muon
chambers, will continue to be part of the experiment.
  The CLEO Constants Database system must provide efficient access to detector
and analysis constants for a wide variety of purposes, such as hardware
configuration, Online operation and monitoring, calibration, and the complete
CLEO analysis framework. Since the original project, implemented through the
Objectivity Object Database Management System, did not meet those requirements,
the system was redesigned from the ground up, using the same technology. It is
currently being introduced into the production environment without significant
interruptions. In this presentation, we will outline the specifications of the
constants database system, and then report on the process that led to the
redesign. Performance comparisons and insights on relevant design aspects will
be shown.


title:
Measurement of Exclusive rho^0 rho^0 Production in Two-Photon Collisions
  at High Q^2 at LEP

abstract:
  Exclusive rho rho production in two-photon collisions involving a single
highly virtual photon is studied with data collected at LEP at centre-of-mass
energies 89GeV < \sqrt{s} < 209GeV with a total integrated luminosity of
854.7pb^-1 The cross section of the process gamma gamma^* -> rho rho is
determined as a function of the photon virtuality, Q^2 and the two-photon
centre-of-mass energy, Wgg, in the kinematic region: 1.2GeV^2 < Q^2 < 30GeV^2
and 1.1GeV < Wgg < 3GeV.


title: Recent results on two-photon and tau physics at BABAR

abstract:
  We present a measurement of the total width, Gamma_tot, and mass, M, of the
eta_c meson with the BABAR detector at the PEP-II B-factory at SLAC. The
results based on a data sample of 88 fb^-1 are Gamma_tot = (33.3 +- 2.5(stat.)
+- 0.8(sys.))MeV and M = (2983.3 +- 1.2 +- 1.8) MeV. An enhancement observed
around 3.63 GeV can be interpreted as an evidence for the eta_c(2S) state. In
addition a preliminary measurement of the tau lepton lifetime using 30.2 fb^-1
is described. The measured tau lifetime is: (290.8 +- 1.5(stat.) +-
1.6(syst.))fs.


title:
Standard FTP and GridFTP protocols for international data transfer in
  Pamela Satellite Space Experiment

abstract:
  Physics applications often involve large amounts of data and/or computing and
often require secure resource sharing across organizational boundaries, and are
thus not easily handled by today's Internet and Web infrastructures. Pamela (a
Payload Antimatter Matter Exploration and Light-nuclei Astrophysics), is a
permanent magnet core facility with a variety of specialized detectors. It
allows the investigation of the cosmic radiation: origin and evolution of
matter in the galaxy, search for antimatter and dark matter of cosmological
significance, understanding of origin and acceleration of relativistic
particles in the galaxy. Pamela will be put in an elliptical orbit at an
altitude between 300 and 600 Km, on board of the Resurs DK1 Russian satellite
in the fall of the year 2003. The Napoli INFN Computing Center and the Pamela
Teams of the Universities of Rome, Trieste and Stockholm have performed several
network tests in order to make a comparison between Standard FTP and GridFTP
protocols.


title: The BaBar Mini

abstract:
  BaBar has recently deployed a new event data format referred to as the Mini.
The Mini uses efficient packing and aggressive noise suppression to represent
the average reconstructed BaBar event in under 7 KBytes. The Mini packs
detector information into simple transient data objects, which are then
aggregated into roughly 10 composite persistent objects per event. The Mini
currently uses Objectivity persistence, and it is being ported to use Root
persistence. The Mini contains enough information to support detailed detector
studies, while remaining small and fast enough to be used directly in physics
analysis. Mini output is customizable, allowing users to both truncate
unnecessary content or add content, depending on their needs. The Mini has now
replaced three older formats as the primary output of BaBar event
reconstruction. A reduced form of the Mini will soon replace the physics
analysis format as well, giving BaBar a single, flexible event data format
covering all its needs.


title: A Web Based Document Database

abstract:
  We describe a document database, developed for BTeV, which has now been
adopted for use by other collaborations. A single web based database and
archival system is used to maintain public and internal documents as well as
documents for a related collaboration. The database performs archiving,
versioning, access control, and easy remote access and submission. We cover the
technical and security requirements of the database and its implementation.
Usage patterns, improvements in our collaborative style, and missteps along the
way are also discussed.


title: NICOS System of Nightly Builds for Distributed Development

abstract:
  NICOS, NIghtly COntrol System, is a flexible tool for coordination of
software development in large-scale projects. It manages the multi-platform
nightly builds based on the recent versions of software packages, tries to
compensate for technical failures, tests the newly built software, identifies
possible problems, and makes results immediately available to developers spread
over different institutions and countries. The NICOS nightly build services
ensure that new software submissions are consistent and provide expected
results. The NICOS tool was developed to coordinate the efforts of more than
100 developers from 34 countries for the ATLAS project at CERN and can be
easily adapted for other large software projects.


title:
Development of a PCI Based Data Acquisition Platform for High Intensity
  Accelerator Experiments

abstract:
  Data logging at an upgraded KEKB accelerator or the J-PARC facility,
currently under commission, requires a high density data acquisition platform
with integrated data reduction CPUs. To follow market trends, we have developed
a DAQ platform based on the PCI bus, a choice which permits a fast DAQ and a
long expected lifetime of the system. The platform is a 9U-VME motherboard
consisting of four slots for signal digitization modules, readout FIFOs for
data buffering, and three PMC slots, on one of which resides a data reduction
CPU. We have performed long term and thermal stability tests. The readout speed
on the platform has been measured up to 125 MB/s in DMA mode.


title: ATLAS Commander: an ATLAS production tool

abstract:
  This paper describes the ATLAS production tool AtCom (for ATLAS Commander).
The purpose of the tool is to automate as much as possible the task of a
production manager: defining and submitting jobs in large quantities, following
up upon their execution, scanning log files for known and unknown errors,
updating the various ATLAS bookkeeping databases on successful completion of a
job whilst cleaning up and resubmitting otherwise. The design of AtCom is
modular, separating the generic basic job management functionality from the
interactions with the various databases on the one hand, and the computing
systems on the other hand. Given the near future reality of different flavors
of computing systems (legacy and GRID) deployed concurrently at the various, or
even a single ATLAS site, AtCom allows several of them to be used at the same
time transparently.


title: Reconstruction and Analysis on Demand: A Success Story

abstract:
  The traditional design of an HEP reconstruction system partitions the problem
into a series of modules. A reconstruction job is then just a sequence of
modules run in a particular order with each module reading data from the event
and placing new data into the event. The problem with such a design is it is up
to the user to place the modules in the correct order and CPU time is wasted
calculating quantities that may not be used if the event is rejected based on
some other criteria.
  The CLEO III analysis/reconstruction system takes a different approach: on
demand processing (otherwise known as lazy evaluation). Jobs are still
partitioned into smaller components which we call Producers. However, Producers
register what data they produce. The first time a datum is requested for an
event the Producer's algorithm is run. Sources work similarly, registering what
data they can retrieve but delaying retrieval until the data is requested. Data
analysis and filtering are done via a separate set of modules called
Processors.
  We have been using this system for four years and it has been a huge success.
The data access implementation has proven to be very easy to use and extremely
efficient. Reconstruction jobs are easy to configure and additional event
filters can be added efficiently and robustly -- access to correct data is
automatically guaranteed. The true test of success: physicists have embraced
this model for analysis even though the old model is still supported.

The Event as an Object-Relational Database: Avoiding the Dependency
  Nightmare

abstract:
  With the use of object-oriented languages for HEP, many experiments have
designed their data objects to contain direct references to other objects in
the event (e.g., tracks and electromagnetic showers have references to each
other to denote matches). Unfortunately this creates tremendous dependencies
between packages which lead to brittle development systems (e.g., if the
electromagnetic code has a problem you may not be able to compile the tracking
code) and makes the storage system more complex.
  We discuss how the CLEO III experiment avoided these problems by treating an
event as an object-relational database. The discussion will include: the
constraints we placed on our objects; our use of a separate Association class
to deal with inter-object references; and our ability to use multiple sources
to supply different data items for one event.


title: RefDB: The Reference Database for CMS Monte Carlo Production

abstract:
  RefDB is the CMS Monte Carlo Reference Database. It is used for recording and
managing all details of physics simulation, reconstruction and analysis
requests, for coordinating task assignments to world-wide distributed Regional
Centers, Grid-enabled or not, and trace their progress rate. RefDB is also the
central database that the workflow-planner contacts in order to get task
instructions. It is automatically and asynchronously updated with book-keeping
run summaries. Finally it is the end-user interface to data catalogues.


title: Supervision of the ATLAS High Level Trigger System

abstract:
  The ATLAS High Level Trigger (HLT) system provides software-based event
selection after the initial LVL1 hardware trigger. It is composed of two
stages, the LVL2 trigger and the Event Filter. The HLT is implemented as
software tasks running on large processor farms. An essential part of the HLT
is the supervision system, which is responsible for configuring, coordinating,
controlling and monitoring the many hundreds of processes running in the HLT. A
prototype implementation of the supervision system, using tools from the ATLAS
Online Software system is presented. Results from scalability tests are also
presented where the supervision system was shown to be capable of controlling
over 1000 HLT processes running on 230 nodes.


title: A Presentation Management System for Collaborative Meetings

abstract:
  Electronic presentations are rapidly becoming the standard for meetings in
large high energy physics collaborations. An attractive solution should combine
a central repository of presentation files with easy uploading and downloading
access over the wide area network. This allows all information to be instantly
shared within the collaboration, including remote participants at meetings. An
ideal system should allow operation of a whole session from a single PC,
without time-consuming switchovers between personal notebooks, and preserve the
information for summary talks etc. On the other hand, there should be no need
for manual collection of documents, and submission of slides should be possible
even seconds before the presentation.
  We present a system developed and currently used by the ZEUS experiment at
DESY. It provides a wide range of functions including registration of
participants, automatic agenda preparation, presentation submission, display
and archiving. A particular emphasis has been put on system security, with
access to the system being made via a secure web interface. Different privilege
levels are available within the system, according to the status of the user:
chairman, speaker or other meeting participant. We also discuss our experience
of using this system in a range of different contexts.


title: A ROOT-based Client-Server Event Display for the ZEUS Experiment

abstract:
  A new event visualization tool for the ZEUS experiment is nearing completion,
which will provide the functionality required by the new detector components
implemented during the recently achieved HERA luminosity upgrade. The new
design is centered around a client-server concept, which allows to obtain
random access to the ZEUS central event store as well as to events taken online
via the HTTP protocol, even from remote locations. The client is a lightweight
C++ application, and the ROOT system is used as underlying toolkit. Particular
attention has been given to a smooth integration of 3-dimensional and layered
2-dimensional visualizations. The functionality of server and client
application with its graphical user interface are presented.


title: Online Monitoring software framework in the ATLAS experiment

abstract:
  A fast, efficient and comprehensive monitoring system is a vital part of any
HEP experiment. This paper describes the software framework that will be used
during ATLAS data taking to monitor the state of the data acquisition and the
quality of physics data in the experiment. The framework has been implemented
by the Online Software group of the ATLAS Trigger&Data Acquisition (TDAQ)
project and has already been used for several years in the ATLAS test beams at
CERN. The inter-process communication in the framework is implemented via
CORBA, which provides portability between different operating systems and
programming languages. This paper will describe the design and the most
important aspects of the online monitoring framework implementation. It will
also show some test results, which indicate the performance and scalability of
the current implementation.


title: Objectivity Data Migration

abstract:
  In this article we describe the migration of event data collected by the
COMPASS and HARP experiments at CERN. Together these experiments have over
300TB of physics data stored in Objectivity/DB that had to be transferred to a
new data management system by the end of Q1 2003 and Q2 2003 respectively. To
achieve this, data needed to be processed with a rate close to 100MB/s,
employing 14 tape drives and a cluster of 30 Linux servers. The new persistency
solution to accommodate the data is built upon relational databases for
metadata storage and standard "flat" files for the event data. The databases
contain collections of 109 events and allow generic queries or direct
navigational access to the data, preserving the original C++ user API. The
central data repository at CERN is implemented using several Oracle9i servers
on Linux and the CERN Mass Storage System CASTOR.


title: BOSS: a tool for batch job monitoring and book-keeping

abstract:
  BOSS (Batch Object Submission System) has been developed to provide real-time
monitoring and bookkeeping of jobs submitted to a compute farm system. The
information is persistently stored in a relational database (MySQL in the
current version) for further processing. By means of user-supplied filters,
BOSS extracts the specific job information to be monitored from the standard
input, output and error of the job itself and stores it in the database in a
structured form that allows easy and efficient access. BOSS has been
successfully used by all CMS Regional Centers for managing Monte Carlo data
productions in 2002. Furthermore in fall 2002 it has been used in a prototype
of the CMS production system deployed on the European DataGrid test bed
demonstrating its ability to be used also in a grid environment.


title: Plans for the Integration of grid tools in the CMS computing environment

abstract:
  The CMS collaboration has a long term need to perform large-scale simulation
efforts, in which physics events are generated and their manifestations in the
CMS detector are simulated. Simulated data are then reconstructed and analyzed
by the physicists to support detector design and the design of the real-time
event filtering algorithms that will be used when CMS is running. Up to year
2002 the distribution of tasks among the different regional centers has been
done mainly through manual operations, even though some tools for data transfer
and centralization of the book-keeping were developed. In 2002 the first
prototypes of CMS distributed productions based on grid middleware have been
deployed, demonstrating that it is possible to use them for real data
production tasks. In this work we present the plans of the CMS experiment for
building a production and analysis environment based on the grid technologies
in time for the next big Data Challenge, which is foreseen for the beginning of
year 2004.


title:
Observation of a Narrow Resonance of Mass 2.46 GeV/c^2 Decaying to
  D_s^*+ pi^0 and Confirmation of the D_sJ^* (2317) State

abstract:
  Using 13.5 inverse fb of e+e- annihilation data collected with the CLEO II
detector we have observed a narrow resonance in the Ds*+pi0 final state, with a
mass near 2.46 GeV. The search for such a state was motivated by the recent
discovery by the BaBar Collaboration of a narrow state at 2.32 GeV, the
DsJ*(2317)+ that decays to Ds+pi0. Reconstructing the Ds+pi0 and Ds*+pi0 final
states in CLEO data, we observe peaks in both of the corresponding
reconstructed mass difference distributions, dM(Dspi0)=M(Dspi0)-M(Ds) and
dM(Ds*pi0)=M(Ds*pi0)-M(Ds*), both of them at values near 350 MeV. We interpret
these peaks as signatures of two distinct states, the DsJ*(2317)+ plus a new
state, designated as the DsJ(2463)+. Because of the similar dM values, each of
these states represents a source of background for the other if photons are
lost, ignored or added. A quantitative accounting of these reflections confirms
that both states exist. We have measured the mean mass differences <dM(Dspi0)>
= 350.0 +/- 1.2 [stat] +/- 1.0 [syst] MeV for the DsJ*(2317) state, and
<dM(Ds*pi0)> = 351.2 +/- 1.7 [stat] +/- 1.0 [syst] MeV for the new DsJ(2463)+
state. We have also searched, but find no evidence, for decays of the two
states via the channels Ds*+gamma, Ds+gamma, and Ds+pi+pi-. The observations of
the two states at 2.32 and 2.46 GeV, in the Ds+pi0 and Ds*+pi0 decay channels
respectively, are consistent with their interpretations as (c anti-strange)
mesons with orbital angular momentum L=1, and spin-parities of 0+ and 1+.


title: The Trigger System of the ARGO-YBJ detector

abstract:
  The ARGO-YBJ experiment has been designed to detect air shower events over a
large size scale and with an energy threshold of a few hundreds GeV. The
building blocks of the ARGO-YBJ detector are single-gap Resistive Plate
Counters (RPCs). The trigger logic selects the events on the basis of their hit
multiplicity. Inclusive triggers as well as dedicated triggers for specific
physics channels or calibration purposes have been developed. This paper
describes the architecture and the main features of the trigger system.


title: Analog read-out of the RPCs in the ARGO-YBJ experiment

abstract:
  The ARGO-YBJ experiment, currently under construction at the Yangbaijing
Laboratory (4300 m a.s.l.), consists of a single layer of about 2000 Resistive
Plate Chambers (RPCs) for a total instrumented area of about 6700 m^2. The
digital read-out, performed by means of pick-up electrodes 6.7 X 62 cm^2
('strips'), allows one to measure the particle number of small size showers. To
extend the size range up to the knee region it is necessary to implement the
charge read-out of the detector chambers. In order to achieve this goal each
RPC has been instrumented with two large size pads of dimensions 140 X 125
cm^2. In this paper the performance of the prototype circuit devoted to the
charge read-out is reported.


title: Online and Offline Computing systems in the PHENIX experiment

abstract:
  PHENIX is one of two large experiments at Brookhaven National Laboratory's
Relativistic Heavy-Ion Collider (RHIC). At the time of the conference, the
PHENIX experiment was about halfway through the 2003 run, which started in
January 2003. In preparation for the run, the PHENIX data acquisition, the
computing infrastructure, and the software have undergone several upgrades.
Those upgrades boost the recorded data rate to about 100 MB/s and allow for a
fast reconstruction only a few weeks after the data have been taken. As part of
the upgrade, essentially all servers in the Online System have been converted
from Solaris to Linux, and a new Linux computing farm has been commissioned at
the experimental site that is used to prepare for a rapid offline
reconstruction pass. This paper presents a general overview of PHENIX
computing. We will explain the current status, the changes, choices of software
and hardware, and discuss our experience with the new setup.


title:
A GRID solution for Gravitational Waves Signal Analysis from Coalescing
  Binaries: preliminary algorithms and tests

abstract:
  The analysis of data coming from interferometric antennas for gravitational
waves detection may require a huge amount of computing power. The usual
approach to the detection strategy is to set-up computer farms able to perform
several tasks in parallel, exchanging data through network links. In this paper
a new computation strategy is presented. This strategy is based on the GRID
environment that allows several geographically distributed computing resources
to exchange data and programs in secure way, using standard infrastructures.
The computing resources can be geographically distributed also on a large
scale. Some preliminary tests were performed using a subnetwork of the GRID
infrastructure, producing good results in terms of distribution efficiency and
time duration.


title:
AGS Super Neutrino Beam Facility Accelerator and Target System Design
  (Neutrino Working Group Report-II)

abstract:
  This document describes the design of the accelerator and target systems for
the AGS Super Neutrino Beam Facility. Under the direction of the Associate
Laboratory Director Tom Kirk, BNL has established a Neutrino Working Group to
explore the scientific case and facility requirements for a very long baseline
neutrino experiment. Results of a study of the physics merit and detector
performance was published in BNL-69395 in October 2002, where it was shown that
a wide-band neutrino beam generated by a 1 MW proton beam from the AGS, coupled
with a half megaton water Cerenkov detector located deep underground in the
former Homestake mine in South Dakota would be able to measure the complete set
of neutrino oscillation parameters.
  This report details the performance requirements and conceptual design of the
accelerator and the target systems for the production of a neutrino beam by a
1.0 MW proton beam from the AGS. The major components of this facility include
a new 1.2 GeV superconducting linac, ramping the AGS at 2.5 Hz, and the new
target station for 1.0 MW beam. It also calls for moderate increase, about 30%,
of the AGS intensity per pulse. Special care is taken to account for all
sources of proton beam loss plus shielding and collimation of stray beam halo
particles to ensure equipment reliability and personal safety. A preliminary
cost estimate and schedule for the accelerator upgrade and target system are
also included.


title: Verification and Diagnostics Framework in ATLAS Trigger/DAQ

abstract:
  Trigger and data acquisition (TDAQ) systems for modern HEP experiments are
composed of thousands of hardware and software components depending on each
other in a very complex manner. Typically, such systems are operated by
non-expert shift operators, which are not aware of system functionality
details. It is therefore necessary to help the operator to control the system
and to minimize system down-time by providing knowledge-based facilities for
automatic testing and verification of system components and also for error
diagnostics and recovery. For this purpose, a verification and diagnostic
framework was developed in the scope of ATLAS TDAQ. The verification
functionality of the framework allows developers to configure simple low-level
tests for any component in a TDAQ configuration. The test can be configured as
one or more processes running on different hosts. The framework organizes tests
in sequences, using knowledge about components hierarchy and dependencies, and
allowing the operator to verify the functionality of any subset of the system.
The diagnostics functionality includes the possibility to analyze the test
results and diagnose detected errors, e.g. by starting additional tests and
understanding reasons of failures. A conclusion about system functionality,
error diagnosis and recovery advice are presented to the operator in a GUI. The
current implementation uses the CLIPS expert system shell for knowledge
representation and reasoning.


title:
Study of hadronic final states from double tagged gammagamma events at
  LEP

abstract:
  The interaction of virtual photons is investigated using double tagged
gammagamma events with hadronic final states recorded by the ALEPH experiment
at e^+e^- centre-of-mass energies between 188 and 209 GeV. The measured cross
section is compared to Monte Carlo models, and to next-to-leading-order QCD and
BFKL calculations.


title: Recent Results from the KLOE Experiment at DAPHNE

abstract:
  Recent results from the KLOE experiment at the DAPHNE e+e- collider are
presented. KLOE has collected about 500 pb^-1 of data in the years from 2000 to
2002. Preliminary results are obtained using wide samples of the full
statistics and include: the BR of the Ke3 decay of the K_S and the first
measurement of its charge asymmetry, the ratio
BR(K_S-->pi+pi-(gamma))/BR(K_S-->pi^0pi^0), the ratio
BR(K_L-->gammagamma)/BR(K_L-->3pi^0), a detailed study of the decay
phi-->pi+pi-pi^0, the ratio BR(phi-->eta' gamma)/BR(phi-->eta gamma) and the
pseudoscalar mixing angle phi_P, the phi-->f_0 gamma and the phi-->a_0 gamma
BR's.


title:
Measurements of Proton Structure Functions, alpha_s and Parton
  Distribution Functions at HERA

abstract:
  The measurement and QCD analysis of neutral and charged current cross
sections at HERA are presented. For the kinematic range of four-momentum
transfer Q^2 between approx. 1 GeV^2 and 30000 GeV^2 and Bjorken x between
0.0013 and 0.65 the data are compared to NLO QCD predictions. In dedicated NLO
QCD analyses the extraction of the parton distribution functions of the proton
is performed. Results for the measurement of the strong coupling constant
alpha_s are presented.


title: Recent Charmonium Physics from BES

abstract:
  Measurements of branching fractions for nine different final states, based on
a data sample of approximately 4 million psi(2S) events collected with the BESI
detector at the BEPC, are reported. Using the same event sample, radiative
decays of the psi (2S) into pi pi, K K-bar and eta eta final states have been
measured.
  Cross sections for e e -> e e, hadrons, pi pi J/psi, and mu mu have been
measured in the vicinity of the psi(2S) resonance using the BESII detector. The
psi(2S) total width; partial widths to hadrons, pi pi J/psi and muons; and
corresponding branching fractions have been determined.
  Decays of J/psi -> gamma eta_c are used to determine the mass and width of
the eta_c using a sample of 58 M J/psi events. $M_{\eta_c} = (2977.5 \pm 1.0
\pm 1.2)$ MeV and $\Gamma_{\eta_c} = (17.0 \pm 3.7 \pm 7.4)$ MeV.
  The first observation of chicJ (J=0,1,2) decays to lambda lambda-bar is
reported using psi(2S) data collected with the BESII detector. Results are
compared with model predictions.


title: New Results from the Cryogenic Dark Matter Search Experiment

abstract:
  Using improved Ge and Si detectors, better neutron shielding, and increased
counting time, the Cryogenic Dark Matter Search (CDMS) experiment has obtained
stricter limits on the cross section of weakly interacting massive particles
(WIMPs) elastically scattering from nuclei. Increased discrimination against
electromagnetic backgrounds and reduction of neutron flux confirm
WIMP-candidate events previously detected by CDMS were consistent with neutrons
and give limits on spin-independent WIMP interactions which are >2X lower than
previous CDMS results for high WIMP mass, and which exclude new parameter space
for WIMPs with mass between 8-20 GeV/c^2.


title: The recent results of solar neutrino measurements in Super-Kamiokande

abstract:
  The results of solar neutrino data from the first phase of Super-Kamiokande
are presented. Super-Kamiokande can measure not only the solar neutrino flux
but also its energy spectrum and its time variations such as day vs night and
seasonal differences. This information can severely restrict parameters of
solar neutrino oscillation. From the combination of several experiments'
results with those of Super-K, the Large Mixing Angle solution is uniquely
allowed at the 98.1% confidence level; this global solar neutrino oscillation
analysis is presented. The current status of the second phase of
Super-Kamiokande is presented.


title:
Limits on D0-D0bar Mixing and CP Violation from the Ratio of Lifetimes
  for Decay to K-pi+, K-K+, and pi-pi+

abstract:
  We present a measurement of $D^0$-$\D0bar$ mixing parameters using the ratios
of lifetimes extracted from samples of $D^0$ mesons decaying to $K^-\pi^+$,
$K^-K^+$, and $\pi^-\pi^+$. Using 91 ${\rm fb}^{-1}$ of data collected by the
BaBar detector at the PEP-II asymmetric-energy $B$ Factory, we obtain a value
$Y = (0.8 \pm 0.4 ({\rm stat.}) {}^{+0.5}_{-0.4} ({\rm syst.}))$%, which, in
the limit of CP conservation, corresponds to the mixing parameter $y =
\Delta\Gamma/2\Gamma$. Using the difference in lifetimes of $D^0$ and $\D0bar$
mesons, we obtain the CP-violation parameter $\Delta Y = (-0.8 \pm 0.6 ({\rm
stat.}) \pm 0.2 ({\rm syst.}))$%.


title:
Recent results on anomalous J/psi suppression in Pb-Pb collisions at 158
  AGeV/c

abstract:
  We report our latest results on charmonium suppression as measured at the
CERN-SPS in Pb-Pb interactions at an incident beam momentum of 158 GeV/c per
nucleon. Preliminary results obtained from the most recent sample of data
collected in year 2000 under improved experimental conditions are compared with
published results. For the most peripheral Pb-Pb collisions, J/psi suppression
agrees with the normal absorption measured from interactions of lighter nuclei
while a steady increasing abnormal supression is observed with increasing
centrality.


title: LEP 1 Heavy Flavour Electroweak Physics and 2-Fermion Processes at LEP 2

abstract:
  Results from heavy flavour electroweak physics at LEP1 are reviewed together
with measurements of 2-fermion processes at LEP2. For the former measurements
the emphasis is on analyses of heavy quark forward-backward asymmetries,
A_FB^b,c, and on the partial decay widths of the Z^0 to heavy quarks, R_b,c.
The measurements of the heavy quark asymmetries are used to extract the
effective electroweak mixing angle for leptons, sin^2(theta_eff^lept). A 2.9
sigma discrepancy between measurements of this quantity from A_l^SLD and from
A_FB^b is observed. The 2-fermion processes at LEP2 are used to place stringent
limits on physics processes beyond the Standard Model. However, all measured
quantities are in reasonable agreement with the Standard Model expectations,
and all calculated limits are well above the highest LEP2 center-of-mass
energies.


title: Higgs Searches at the Tevatron

abstract:
  One of the highest priority physics goals for the upgraded Tevatron
experiments, CDF and D0, is the search for the Higgs boson. We present the
initial results from both experiments, based on 40--90 pb$^{-1}$ integrated
luminosity, of Higgs searches in several final states, including $WH$ and $ZH$,
$H\to WW$, and doubly-charged Higgs.


title: Observation of B+ -> rho+ rho0

abstract:
  We report the first observation of the charmless vector-vector decay process
B+ ->rho+ rho0. The measurement uses a 78 fb^{-1} data sample collected with
the Belle detector at the KEKB asymmetric e+e- collider operating at the
Upsilon(4S) resonance. We obtain a branching fraction of Br(B+ ->rho+
rho0)=(31.7+-7.1(stat.)+3.8-6.7(sys.))*10^{-6}. An analysis of the rho
helicity-angle distributions gives a longitudinal polarization of
Gamma_{L}/Gamma=(94.8+-10.6(stat.)+-2.1(sys.))%.


title: W and Z Cross Sections at the Tevatron

abstract:
  The CDF and D0 experiments at the Tevatron have used p-pbar collisions at
sqrt(s)=1.96 TeV to measure the cross section of W and Z boson production using
several leptonic final states. An indirect measurement of the total W width has
been extracted, and the lepton charge asymmetry in Drell-Yan production has
been studied up to invariant masses of 600 GeV/c^2.


title:
The Algorithm Steering and Trigger Decision mechanism of the ATLAS High
  Level Trigger

abstract:
  Given the extremely high output rate foreseen at LHC and the general-purpose
nature of ATLAS experiment, an efficient and flexible way to select events in
the High Level Trigger is needed. An extremely flexible solution is proposed
that allows for early rejection of unwanted events and an easily configurable
way to choose algorithms and to specify the criteria for trigger decisions. It
is implemented in the standard ATLAS object-oriented software framework,
Athena. The early rejection is achieved by breaking the decision process down
into sequential steps. The configuration of each step defines sequences of
algorithms which should be used to process the data, and 'trigger menus' that
define which physics signatures must be satisfied to continue on to the next
step, and ultimately to accept the event. A navigation system has been built on
top of the standard Athena transient store (StoreGate) to link the event data
together in a tree-like structure. This is fundamental to the seeding
mechanism, by which data from one step is presented to the next. The design
makes it straightforward to utilize existing off-line reconstruction data
classes and algorithms when they are suitable


title: Determination of neutrino masses, present and future

abstract:
  Oscillation experiments show that neutrinos have masses. They however only
determine the neutrinop mass differences. Information on the absolute masses
can be obtained by studying the kinematics in weak decays, or by searching for
neutrinoless double beta decay. Recent results are reviewed, as well as future
projects.


title: Vector meson production and inclusive KsKs final state at HERA

abstract:
  Measurements of vector mesons at HERA allow a detailed study of diffractive
and non-diffractive production mechanisms, fragmentation and decay branching
ratios. Results are presented on hadronic resonance measurements. In addition,
the first observation of two meson states at masses around 1500 MeV and 1700
MeV are reported using inclusive KsKs production in deep inelastic ep
scattering in ZEUS at HERA.


title: Recent NA48 results on rare kaon decays

abstract:
  Recent NA48 results from detailed studies of $K_{L,S}\to \pi^+ \pi^- e^+ e^-$
and $K_S\to\pi^0 \gamma\gamma$ decay modes are presented. The results are based
on the data collected with the NA48 detector at the CERN SPS during the
1998-199 9 and 2000 data taking periods, respectively. Prospects for future
results on charged kaon decays are briefly described.


title:
Diffractive Photoproduction of J/psi Mesons with Large Momentum Transfer
  at HERA

abstract:
  The diffractive photoproduction of J/psi mesons is measured with the H1
detector at the ep collider HERA using an integrated luminosity of 78 pb^-1.
The differential cross section d sigma(gamma p -> J/psi Y) / d t is studied in
the range 2 < |t| < 30 GeV^2, where t is the square of the four-momentum
transferred at the proton vertex. The cross section is also presented as a
function of the photon-proton centre-of-mass energy W in three t intervals,
spanning the range 50 < W < 200 GeV. A fast rise of the cross section with W is
observed for each t range and the slope for the effective linear Pomeron
trajectory is measured to be alpha^\prime= -0.0135 \pm 0.0074 (stat.) \pm
0.0051 (syst.) GeV^-2. The measurements are compared with perturbative QCD
models based on BFKL and DGLAP evolution. The data are found to be compatible
with s-channel helicity conservation.


title:
Measurements of muon flux at 1070 metres vertical depth in the Boulby
  underground laboratory

abstract:
  Measurements of cosmic-ray muon rates and energy deposition spectra in a one
tonne liquid scintillator detector at 1070 metres vertical depth in the Boulby
underground laboratory are discussed. In addition, the simulations used to
model the detector are described. The results of the simulations are compared
to the experimental data and conclusions given. The muon flux in the laboratory
is found to be (4.09+/-0.15)x10^-8 /cm^2/s.


title: Comment on "e+ e- annhilation into J/psi J/psi"

abstract:
  Using a data sample of 101.8 fb collected by the Belle detector at the KEKB
asymmetric energy e+ e- collider, we confirm our published observation of e+ e-
-> J/psi eta_c and find no evidence for the process e+ e- -> J/psi J/psi. The
latter process was suggested as means to explain the large discrepancy between
the published Belle result and theoretical predictions.


title: Search for Excited Leptons at LEP

abstract:
  A search for charged and neutral excited leptons is performed in 217 pb^-1 of
e+e- collision data collected with the L3 detector at LEP at centre-of-mass
energies from 202 GeV up to 209 GeV. The pair- and single-production mechanisms
of excited electrons, muons and taus, as well as of excited electron-, muon-
and tau-neutrinos,are investigated and no signals are detected. Combining with
L3 results from searches at lower centre-of-mass energies, gives improved
limits on the masses and couplings of excited leptons.


title: Proton-Antiproton Pair Production in Two-Photon Collisions at LEP

abstract:
  The reaction e^+e^- -> e^+e^- proton antiproton is studied with the L3
detector at LEP. The analysis is based on data collected at e^+e^-
center-of-mass energies from 183 GeV to 209 GeV, corresponding to an integrated
luminosity of 667 pb^-1. The gamma gamma -> proton antiproton differential
cross section is measured in the range of the two-photon center-of-mass energy
from 2.1 GeV to 4.5 GeV. The results are compared to the predictions of the
three-quark and quark-diquark models.


title: Jet production in charged current deep inelastic e+p scattering at HERA

abstract:
  The production rates and substructure of jets have been studied in charged
current deep inelastic e+p scattering for Q**2>200 GeV**2 with the ZEUS
detector at HERA using an integrated luminosity of 110.5 pb**-1. Inclusive jet
cross sections are presented for jets with transverse energies E_T(jet) > 14
GeV and pseudorapidities in the range -1 < eta(jet) < 2. Dijet cross sections
are presented for events with a jet having E_T(jet) > 14 GeV and a second jet
having E_T(jet) > 5 GeV. Measurements of the mean subjet multiplicity, <n_sbj>,
of the inclusive jet sample are presented. Predictions based on parton-shower
Monte Carlo models and next-to-leading-order QCD calculations a re compared to
the measurements. The value of alphas(M_Z), determined from <n_sbj> at
y_cut=0.01 for jets with 25<E_T(jet)<119 GeV, is alphas(M_Z) = 0.1202 +-0.0052
(stat.) +0.0060-0.0019 (syst.) +0.0065-0.0053 (th.). The mean subjet
multiplicity as a function of Q**2 is found to be consistent with that measured
in NC DIS.


title: Cabibbo-Suppressed Decays of D^+ to pi^+ pi^0, K^+ K^0, and K^+ pi^0

abstract:
  Using a data sample corresponding to 13.7 fb^-1 collected with the CLEO II
and II.V detectors, we report new branching fraction measurements for two
Cabibbo-suppressed decay modes of the D^+ meson: Br(D^+ to pi^+ pi^0) = (1.3
+/- 0.2) x 10^-3 and Br(D^+ to \bar{K}^0 K^+) = (5.2 +/- 0.6) x 10^-3 which are
significant improvements over past measurements. The errors include statistical
and systematical uncertainties as well as the uncertainty in the absolute D^+
branching fraction scale. We also set the first 90% confidence level upper
limit on the branching fraction of the doubly Cabibbo-suppressed decay mode
Br(D^+ to K^+ pi^0) < 4.2 x 10^-4.


title: Measurements of |Vub| at Belle

abstract:
  We have tried to measure $|V_{ub}|$ using inclusive semileptonic decay
measurements with three different methods. The full reconstruction tag is the
one of the most feasible method to measure inclusive process. Semileptonic
$B\to D^{(*)}\ell\nu$ tag is another method to separate signal and tag $B$
mesons. New kinematic variable is used to enhance double semileptonic decays of
both $B$ meson. We also improve the neutrino reconstruction technique solving a
combination of decay products into signal and tag $B$ mesons using the
simulated annealing method.


title:
Tests of model of color reconnection and a search for glueballs using
  gluon jets with a rapidity gap

abstract:
  Gluon jets with a mean energy of 22 GeV and purity of 95% are selected from
hadronic Z0 decay events produced in e+e- annihilations. A subsample of these
jets is identified which exhibits a large gap in the rapidity distribution of
particles within the jet. After imposing the requirement of a rapidity gap, the
gluon jet purity is 86%. These jets are observed to demonstrate a high degree
of sensitivity to the presence of color reconnection, i.e. higher order QCD
processes affecting the underlying color structure. We use our data to test
three QCD models which include a simulation of color reconnection: one in the
Ariadne Monte Carlo, one in the Herwig Monte Carlo, and the other by Rathsman
in the Pythia Monte Carlo. We find the Rathsman and Ariadne color reconnection
models can describe our gluon jet measurements only if very large values are
used for the cutoff parameters which serve to terminate the parton showers, and
that the description of inclusive Z0 data is significantly degraded in this
case. We conclude that color reconnection as implemented by these two models is
disfavored. The signal from the Herwig color reconnection model is less clear
and we do not obtain a definite conclusion concerning this model. In a separate
study, we follow recent theoretical suggestions and search for glueball-like
objects in the leading part of the gluon jets. No clear evidence is observed
for these objects.


title: Prediction of Neutrino Fluxes in the NOMAD Experiment

abstract:
  The method developed for the calculation of the flux and composition of the
West Area Neutrino Beam used by NOMAD in its search for neutrino oscillations
is described. The calculation is based on particle production rates computed
using a recent version of FLUKA and modified to take into account the cross
sections measured by the SPY and NA20 experiments. These particles are
propagated through the beam line taking into account the material and magnetic
fields they traverse. The neutrinos produced through their decays are tracked
to the NOMAD detector. The fluxes of the four neutrino flavours at NOMAD are
predicted with an uncertainty of about 8% for nu(mu) and nu(e), 10% for
antinu(mu), and 12% for antinu(e). The energy-dependent uncertainty achieved on
the R(e, mu) prediction needed for a nu(mu)->nu(e) oscillation search ranges
from 4% to 7%, whereas the overall normalization uncertainty on this ratio is
4.2%.


title: First Production and Detection of Cold Antihydrogen Atoms

abstract:
  The ATHENA experiment recently produced the first atoms of cold antihydrogen.
This paper gives a brief review of how this was achieved.


title: Diffraction in ep collisions

abstract:
  Recent measurements of the diffractive deep-inelastic cross section are used
to extract diffractive parton densities of the proton. These are subsequently
applied in models to predict the production of jets and open charm in the final
state. A rapidity gap suppression factor for dijet production in diffractive
photoproduction relative to diffractive deep-inelastic scattering is obtained
using a model-independent comparison.


title: Measurements of Diffractive Processes at CDF

abstract:
  We review the results of measurements on hard diffractive processes performed
by the CDF Collaboration and report preliminary CDF results on two soft
diffractive processes with a leading antiproton and a rapidity gap in addition
to that associated with the antiproton. All results have been obtained from
data collected in Run I of the Fermilab Tevatron $\bar pp$ collider.


title: Recent results on Vub, Vcb and Mixing from the BaBar Experiment

abstract:
  We present the measurements of the CKM matrix parameters Vub, Vcb and of the
B mixing oscillation frequency with the BaBar experiment at the asymmetric
B-factory PEPII. Data were collected in the years 2000-2002 and the total
available statistics corresponds to 91 fb-1. The Vub, Vcb measurements utilize
both inclusive and exclusive semileptonic decays of the $B$ meson. The
Delta(md) parameter is measured by using the time evolution of the B,
determined from the flight length difference between the two B mesons.


title: Status report on the NEMO3 experiment

abstract:
  The NEMO3 detector, now operating in the Frejus Underground Laboratory, is
devoted to search for neutrinoless double beta decay; the expected sensitivity
for the effective neutrino mass is on the order of 0.1 eV. The performances of
the tracking detector are presented. The first and very preliminary results
concerning the background and the double beta signal are given.


title:
Coherent Pair Production by Photons in the 20-170 GeV Energy Range
  Incident on Crystals and Birefringence

abstract:
  The cross section for coherent pair production by linearly polarised photons
in the 20-170 GeV energy range was measured for photon aligned incidence on
ultra-high quality diamond and germanium crystals. The theoretical description
of coherent bremsstrahlung and coherent pair production phenomena is an area of
active theoretical debate and development. However, under our experimental
conditions, the theory predicted the combined cross section and polarisation
experimental observables very well indeed. In macroscopic terms, our experiment
measured a birefringence effect in pair production in a crystal. This study of
this effect also constituted a measurement of the energy dependent linear
polarisation of photons produced by coherent bremsstrahlung in aligned
crystals. New technologies for manipulating high energy photon beams can be
realised based on an improved understanding of QED phenomena at these energies.
In particular, this experiment demonstrates an efficient new polarimetry
technique. The pair production measurements were done using two independent
methods simultaneously. The more complex method using a magnet spectrometer
showed that the simpler method using a multiplicity detector was also viable.


title: Precise measurement of $\sin^22\theta_{13}$ using Japanese Reactors

abstract:
  After the KamLAND results, the remaining important targets in neutrino
experiments are to measure still unknown 3 basic parameters; absolute neutrino
mass scale, CP violation phase $\delta_{CP}$ and last mixing angle
$\theta_{13}$. The angle $\theta_{13}$ among them is expected to be measured in
near future by long baseline accelerator experiments and reactor experiments.
In this paper, a realistic idea of high sensitivity reactor measurement of
$\sin^22\theta_{13}$ is described. This experiment uses a giant nuclear power
plant as the neutrino source and three identical detectors are used to cancel
detector and neutrino flux uncertainties. The sensitivity reach on
$\sin^22\theta_{13}$ is $0.017\sim0.026$ at $\Delta m^2_{13} \sim 3 \times
10^{-3}eV^2$, which is five to seven times better than the current upper limit
measured by CHOOZ.


title:
Measurements of Branching Fractions and CP-Violating Asymmetries in B0
  -> rho+- h-+ Decays

abstract:
  We present measurements of branching fractions and CP-violating asymmetries
in B0 -> rho+- pi-+ and B0 -> rho- K+ decays. The results are obtained from a
data sample of 88.9 10^6 Upsilon(4S) -> B Bbar decays collected with the BABAR
detector at the PEP-II asymmetric-energy B Factory at SLAC. From a
time-dependent maximum likelihood fit we measure the charge-averaged branching
fractions B(B0 -> rho+- pi-+) = (22.6 +- 1.8(stat) +- 2.2(syst)) 10^(-6) and
B(B0 -> rho- K+) = (7.3 +1.3 -1.2 +- 1.3) 10^(-6); and the CP-violating charge
asymmetries Acp(rho pi) = -0.18 +- 0.08 +- 0.03 and Acp(rho K) = 0.28 +- 0.17
+- 0.08; the direct CP violation parameter C(rho pi) = 0.36 +- 0.18 +- 0.04 and
the mixing-induced CP violation parameter S(rho pi) = 0.19 +- 0.24 +- 0.03; and
the dilution parameters dC(rho pi) = 0.28 +0.18 -0.19 +- 0.04 and dS(rho pi) =
0.15 +- 0.25 +- 0.03.


title: Using Reactors to Measure $\theta_{13}$

abstract:
  A next-generation neutrino oscillation experiment using reactor neutrinos
could give important information on the size of mixing angle $\theta_{13}$. The
motivation and goals for a new reactor measurement are discussed in the context
of other measurements using off-axis accelerator neutrino beams. The reactor
measurements give a clean measure of the mixing angle without ambiguities
associated with the size of the other mixing angles, matter effects, and
effects due to CP violation. The key question is whether a next-generation
experiment can reach the needed sensitivity goals to make a measurement for
$\sin^{2}2\theta_{13}$ at the 0.01 level. The limiting factors associated with
a reactor disappearance measurement are described with some ideas of how
sensitivities can be improved. Examples of possible experimental setups are
presented and compared with respect to cost and sensitivity.


title: Charmonium Production at FNAL-E835 - Triplet P States

abstract:
  Fermilab experiment E835 has done an extensive set of studies on charmonium
triplet P states. The most precise measurements on mass and total width come
indeed from charmonium spectroscopy by direct formation of $c\bar{c}$ states in
$\bar{p}p$ annihilations. Results on both partial widths and higher multipoles
radiative transitions $\chi_{cJ} \to J/\psi \gamma \to \gamma e^+ e^-$ are
given, together with the $\gamma \gamma$ widths of $\chi_{c0}$ and $\chi_{c2}$.
For the first time in hadronic charmonium production, hadronic annihilation
channels ($\pi^0 \pi^0$ and $\eta \eta$) have been clearly identified at the
$\chi_{c0}$ resonance.


title: Search for the Standard Model Higgs Boson at LEP

abstract:
  The four LEP collaborations, ALEPH, DELPHI, L3 and OPAL, have collected a
total of 2461 pb-1 of e+e- collision data at centre-of-mass energies between
189 and 209 GeV. The data are used to search for the Standard Model Higgs
boson. The search results of the four collaborations are combined and examined
in a likelihood test for their consistency with two hypotheses: the background
hypothesis and the signal plus background hypothesis. The corresponding
confidences have been computed as functions of the hypothetical Higgs boson
mass. A lower bound of 114.4 GeV/c2 is established, at the 95% confidence
level, on the mass of the Standard Model Higgs boson. The LEP data are also
used to set upper bounds on the HZZ coupling for various assumptions concerning
the decay of the Higgs boson.


title: Linac-Ring Type Colliders: Second Way to TeV Scale

abstract:
  Main parameters and the physics search potentials of the linac-ring type
lepton-hadron and photon-hadron colliders are discussed. The THERA (TESLA on
HERA), NLC-LHC and CLIC-VLHC proposals are considered.


title: New QCD Results from NuTeV

abstract:
  Preliminary results from next-to-leading order strange sea fits to the
NuTeV's deep inelastic scattering charged-current dimuon cross section data are
presented. Preliminary neutrino and antineutrino inclusive charged-current
differential cross sections and preliminary structure function $F_2(x,Q^2)$ are
presented.


title:
Improved Measurement of the Form Factors and First Search for CP
  Violation in the Decay of Lambda_c^+ to Lambda e^+ nu_e

abstract:
  Using the CLEO detector at the Cornell Electron Storage Ring we have studied
the angular distributions in the decay Lambda_c^+ to Lambda e+ nu_e. By
performing a four-dimensional maximum likelihood fit, we extract the form
factor ratio, R = f_2/f_1, and the pole mass, which determines the shape of the
form factors, M_{pole}. They are found to be -0.31 +/- 0.05_{stat} +/-
0.04_{syst}$ and (2.13 +/- 0.07_{stat} +/- 0.10_{syst}) GeV/c^2, respectively.
These results correspond to the following value of the decay asymmetry
parameter: alpha_{Lambda_c} = -0.85 +/- {0.03}_{stat} +/- 0.02_{sys}, for <q^2>
= 0.67 (GeV/c^2)^2. We search for CP violation in the angular distributions of
the decay and find no evidence for CP violation, obtaining anasymmetry ratio;
A_{Lambda_{c}} = (alpha_{Lambda_c} + alpha_{\bar{Lambda}_c}) /
(alpha_{Lambda_c} - alpha_{\bar{Lambda}_c}) = 0.01 +/- 0.03_{stat} +/-
0.01_{sys} +/- 0.02_{A_{Lambda}}, where the third error is from the uncertainty
in the world average of the CP violating parameter, A_{Lambda}, for Lambda
decay to p pi^-. All results presented in this paper are preliminary.


title: Search for nu(mu)-->nu(e) Oscillations in the NOMAD Experiment

abstract:
  We present the results of a search for nu(mu)-->nu(e) oscillations in the
NOMAD experiment at CERN. The experiment looked for the appearance of nu(e) in
a predominantly nu(mu) wide-band neutrino beam at the CERN SPS. No evidence for
oscillations was found. The 90% confidence limits obtained are delta m^2 < 0.4
eV^2 for maximal mixing and sin^2(2theta) < 1.4x10^{-3} for large delta m^2.
This result excludes the LSND allowed region of oscillation parameters with
delta m^2 > 10 eV^2.


title: Search for the Radiative Decays B -> rho gamma and B0 -> omega gamma

abstract:
  A search for the exclusive radiative decays B --> rho(770) gamma and B0 -->
omega(782) gamma is performed on a sample of about 84\times 10^{6} B\bar B
events collected by the BaBar detector at the PEP-II asymmetric-energy e+e-
storage ring. No significant signal is seen in any of the channels. We set
upper limits on the branching fractions of BR(B^0 -> rho^0 gamma) < 1.2 \times
10^{-6}, BR(B^+ -> rho^+ gamma) < 2.1 \times 10^{-6}, and BR(B^0 -> omega
gamma) < 1.0 \times 10^{-6} at 90% confidence level (C.L.). Using the
assumption that Gamma(B --> rho gamma) = Gamma(B+ --> rho+ gamma)
=2\times\Gamma(B0 --> rho0 gamma), we find the combined limit BR(B --> rho
gamma)<1.9 \times 10^{-6}, corresponding to BR(B --> rho gamma)/\BR(B --> K*
gamma) < 0.047 at 90% C.L.


title:
A Cicerone for the physics of charm, Part I: production, spectroscopy,
  lifetimes

abstract:
  This is part I of a two-part review of charm physics.
  After briefly recapitulating the history of the charm quantum number we
sketch the experimental environments and instruments employed to study the
behaviour of charm hadrons and then describe the theoretical tools for treating
charm dynamics. After discussing a wide range of inclusive production processes
we analyze the spectroscopy of hadrons with hidden and open charm and the weak
lifetimes of charm mesons and baryons.
  In part II we shall address exclusive charm decays, $D^0 - \bar D^0$
oscillations and CP violation.
  This review is meant to be both a pedagogical introduction for the young
scholar and a useful reference for the experienced researcher. We aim for a
complete description of the fundamental features while providing a guide
through the literature for purely technical issues.


title: Detection of partial polarization in Compton scattered photons

abstract:
  It has been recently proposed (Boggs, Nucl. Instr. and Meth. A 503 (2003)
562), to use polarization of Compton scattered gamma-rays to improve the
imaging performance of Compton telescopes. Building upon that work, we detected
the aforementioned polarization in a sample of 1.836 MeV gamma-rays from the
LXeGRIT Compton telescope. Here we present the measurement, together with
detector oriented considerations on the application of the principle to a
realistic Compton telescope.


title:
Linear to Circular Polarisation Conversion using Birefringent Properties
  of Aligned Crystals for Multi-GeV Photons

abstract:
  We present the first experimental results on the use of a thick aligned Si
crystal acting as a quarter wave plate to induce a degree of circular
polarisation in a high energy linearly polarised photon beam. The linearly
polarised photon beam is produced from coherent bremsstrahlung radiation by 178
GeV unpolarised electrons incident on an aligned Si crystal, acting as a
radiator. The linear polarisation of the photon beam is characterised by
measuring the asymmetry in electron-positron pair production in a Ge crystal,
for different crystal orientations. The Ge crystal therefore acts as an
analyser. The birefringence phenomenon, which converts the linear polarisation
to circular polarisation, is observed by letting the linearly polarised photons
beam pass through a thick Si quarter wave plate crystal, and then measuring the
asymmetry in electron-positron pair production again for a selection of
relative angles between the crystallographic planes of the radiator, analyser
and quarter wave plate. The systematics of the difference between the measured
asymmetries with and without the quarter wave plate are predicted by theory to
reveal an evolution in the Stokes parameters from which the appearance of a
circularly polarised component in the photon beam can be demonstrated. The
measured magnitude of the circularly polarised component was consistent with
the theoretical predictions, and therefore is in indication of the existence of
the birefringence effect.


title: LHC Detector Upgrades

abstract:
  The LHC detectors are well into their construction phase. The LHC schedule
shows first beam to ATLAS and CMS in 2007. Because the LHC accelerator has
begun to plan for a ten fold increase in LHC design luminosity (the SLHC or
super LHC) it is none too soon to begin to think about the upgrades which will
be required of the present LHC detectors. In particular, the tracking systems
of ATLAS and CMS will need to be completely rebuilt. Given the time needed to
do the R&D, make prototypes, and construct the new detectors and given the
accelerator schedule for the SLHC, work needs to begin rather soon.


title:
The Results of Oscillation Analysis in K2K Experiment And An Overview of
  JHFnu Experiment

abstract:
  This paper presents the results of oscillation analysis in K2K experiment.
The results show indications of neutrino oscillation and give a new constraint
on the oscillation parameters. The difference of neutrino masses squared
$\Delta m^2$ lies between 1.5 and 3.9$\times10^{-3} {\rm eV}^2$ at $\sin^2
2\theta=1$ with the confidence level of 90%. In addition to these results, a
brief overview of future long-baseline neutrino experiment in Japan, JHF-$\nu$
experiment, is also given in this paper.


title: Critical Issues in Linear Colliders

abstract:
  Linear colliders (LC) on the energy 0.5-1 TeV are considered as the next step
in the particle physics. High acceleration gradients, small beam sizes,
precision tolerances, beam collision effects are main problems for linear
colliders. In this paper we discuss physics motivation, parameters and status
of current LC projects, e+e-, gamma-gamma and gamma-electron modes of
operation, physical limitations on the energy and luminosity. Present
technologies allow to reach energies about 5 TeV with adequate luminosities.
Advanced technique based on plasma and laser method of acceleration can provide
much higher accelerating gradients, however, perspectives of these methods for
high energy colliders are still under big question. Linear colliders with
energies above 10 TeV are hard for any acceleration technology. Speculations on
possibility of PeV linear colliders based on ponderomotive laser acceleration
are just not serious and contain several mistakes on conceptual level. It is
shown that due to radiation in the transverse laser field, methods of
acceleration based on laser bunch ``pressure'' do not work at high energies.


title:
Limits on Production of Magnetic Monopoles Utilizing Samples from the DO
  and CDF Detectors at the Tevatron

abstract:
  We present 90% confidence level limits on magnetic monopole production at the
Fermilab Tevatron from three sets of samples obtained from the D0 and CDF
detectors each exposed to a proton-antiproton luminosity of $\sim175 {pb}^{-1}$
(experiment E-882). Limits are obtained for the production cross-sections and
masses for low-mass accelerator-produced pointlike Dirac monopoles trapped and
bound in material surrounding the D0 and CDF collision regions. In the absence
of a complete quantum field theory of magnetic charge, we estimate these limits
on the basis of a Drell-Yan model. These results (for magnetic charge values of
1, 2, 3, and 6 times the minimum Dirac charge) extend and improve previously
published bounds.


title: The CDF Experiment at the Tevatron - the First Two Years of Run II

abstract:
  The 1992-1995 running of the Fermilab Tevatron ended with many important
physics goals accomplished, including the discovery of the top quark, and the
anticipation of many further questions to be answered in the future. After many
upgrades to the detector and to the accelerator complex, Run II began in April
2001. First results obtained by the Collider Detector at Fermilab (CDF)
collaboration from the analysis of early Tevatron Run II data are reported
here. They fall in two categories: a number of measurements have been performed
with the primary goal of establishing detector performance and physics
potential. Another set of measurements make use of completely new capabilities
of the upgraded detector, thus allowing for competitive results with a modest
amount of integrated luminosity.


title: Measurement of Decay Parameters for $\Xi^{-} \to \Lambda \pi^{-}$ Decay

abstract:
  Based on 1.35 million polarized $\Xi^{-}$ events, we measure the parameter
$\phi_{\Xi}$ to be $-1.61^{\circ} \pm 2.66^{\circ} \pm 0.37^{\circ}$ for
$\Xi^{-} \to \Lambda \pi^{-}$ decay. New results for the parameters
$\beta_{\Xi}$ and $\gamma_{\Xi}$ are also presented. Assuming that the
CP-violating phase-shift difference is negligible, we deduce the strong
phase-shift difference between the P-wave and S-wave amplitudes of the
$\Lambda\pi$ final state to be $3.17^{\circ} \pm 5.28^{\circ} \pm
0.73^{\circ}$. This strong phase-shift difference reduces the theoretical
uncertainty in estimating the level of CP violation in $\Xi$-hyperon decay.


title: A Dalitz Plot Analysis of D0 -> pi+ pi- pi0 Decays in CLEO II.V

abstract:
  Using the 9 inverse femtobarn data sample collected with the CLEO II.V
detector at the Cornell Electron Storage Ring, we have studied the resonant
substructure of the Cabibbo suppressed decay D0 -> pi+ pi- pi0. We observe
significant contributions from the rho- pi+, rho+ pi-, rho0 pi0, and
non-resonant channels, and present preliminary results of the amplitudes,
phases, and fit fractions for these sub-modes. No evidence for the sigma(500)
or more massive rho resonances was found. We observe no CP violation, finding
Acp = 0.01 +0.09 -0.07 +- 0.09.


title:
Search for Rare and Forbidden 3-body Di-muon Decays of the Charmed
  Mesons D+ and Ds+

abstract:
  Using a high statistics sample of photo-produced charm particles from the
FOCUS experiment at Fermilab, we report results of a search for eight rare and
Standard-Model-forbidden decays: D+, Ds+ > h+/- muon-/+ muon+ (with h=pion or
Kaon). Improvement over previous results by a factor of 1.7--14 is realized.
Our branching ratio upper limit D+ > pion+ muon- muon+ of 8.8E-6 at the 90%
C.L. is below the current MSSM R-Parity violating constraint.


title: New precision measurement of the $J/\psi$- and $\psi'$ -meson masses

abstract:
  A new high precision measurement of the $J/\psi$- and $\psi'$-meson masses
has been performed at the VEPP-4M collider using the KEDR detector. The
resonant depolarization method has been employed for the absolute calibration
of the beam energy. The following mass values have been obtained:
  $M_{J/\psi} = 3096.917 \pm 0.010 \pm 0.007$ MeV,
  $M_{\psi'} = 3686.111 \pm 0.025 \pm 0.009$ MeV.
  The relative measurement accuracy has reached $4. 10^{-6}$ for $J/\psi$ and
$7. 10^{-6}$ for $\psi'$, approximately 3 times better than in the previous
precise experiments.


title: The LHCb Trigger Strategy and Performance

abstract:
  We give an outline of the LHCb trigger strategy and performance. The first
and second levels (called L0 and L1) are discussed in some detail, while the
subsequent Higher Level Trigger (HLT), which is currently under development, is
only briefly described.


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

abstract:
  We present a measurement of time-dependent CP asymmetries and an updated
determination of the CP-odd fraction in the decay B0 --> D*+D*- using a data
sample of 88 x 10^6 BBbar pairs collected by the BABAR detector at the PEP-II B
Factory at SLAC. We determine the CP-odd fraction to be 0.063 +/- 0.055(stat)
+/- 0.009(syst). The time-dependent CP asymmetry parameters $Im(\lambda_+)$ and
$|\lambda_+|$ are determined to be 0.05 +/- 0.29(stat) +/- 0.10(syst) and 0.75
+/- 0.19(stat) +/- 0.02(syst), respectively. The Standard Model predicts these
parameters to be -sin2beta and 1, respectively, in the absence of penguin
diagram contributions.


title:
Megaton Modular Multi-Purpose Neutrino Detector for a Program of Physics
  in the Homestake DUSEL

abstract:
  This is a preliminary version of a formal proposal by the 3M collaboration to
construct a megaton, modular, multipurpose (3M) neutrino detector for a program
of experiments in neutrino physics. The detector components will be located in
chambers approximately 7000 ft below the Earth's surface in the Homestake Mine
at Lead, South Dakota, to carry out experiments on neutrino oscillations
directed toward the principal experimental goal of the program, viz., the issue
of CP-invariance violation in the lepton sector of elementary particles, an
issue that has been the subject of study in the quark sector for several
decades. The principal physics goal of this program also requires a moderately
intense neutrino beam from an accelerator located a long distance from the
detector array, such as the 2540 km distance of BNL from Homestake. The
construction plan for that neutrino beam is at http://nwg.phy.bnl.gov/.
  Other experimental searches that do not require the accelerator-generated
beam can be carried out with the 3M detector independently of and at the same
time as the neutrino oscillation and CP-invariance violation measurements are
in progress. They are searches for Proton Decay, UHE Neutrinos, and Supernovae
Neutrinos.


title: Heavy Flavour Lifetimes and Lifetime Differences

abstract:
  We give an overview of heavy flavour lifetime measurements, focusing on
recent results from the Tevatron and the B factories.


title:
Measurement of Inclusive Monmentum Spectra and Multiplicity
  Distributions of Charged Particles at $\sqrt{s}\sim 2-5$ GeV

abstract:
  Inclusive momentum spectra and multiplicity distributions of charged
particles measured with BESII detector at center of mass energies of
2.2,2.6,3.0,3.2,4.6 and 4.8 GeV are presented. Values of the second binomial
moment, $R_2$, obtained from the multiplicity distributions are reported. These
results are compared with both experimental data from high energy $e^+e^-$,
$ep$ and $p\bar{p}$ experiments and QCD calculations.


title: Overview of results from the STAR experiment at RHIC

abstract:
  The Relativistic Heavy-Ion Collider (RHIC) provides Au+Au collisions at
energies up to \sqrtsNN=200 GeV. STAR experiment was designed and constructed
to investigate the behavior of strongly interacting matter at high energy
density. An overview of some of the recent results from the STAR collaboration
is given.


title: The neutrino mass direct measurements

abstract:
  One of the most important tasks in neutrino physics is to determine the
neutrino mass scale to distinguish between hierarchical and degenerate neutrino
mass models and to clarify the role of neutrinos as dark matter particles in
the universe. 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 an unprecedented precision, is being prepared to reach a
sensitivity of 0.2 eV.


title: Measurements of DVCS and High |t| Vector Meson Production at HERA

abstract:
  Measurements of Deeply Virtual Compton Scattering (DVCS) are presented using
data collected by the H1 and ZEUS experiments at HERA. The transition from a
virtual photon to an on-shell particle is expected to necessitate the use of
skewed parton distributions for a theoretical description. The results are
compared to theoretical predictions. Diffractive vector meson production
measurements from H1 and ZEUS are also presented in which the magnitude of the
four-momentum transfer squared |t| at the proton vertex is large. A large |t|
is expected to make it possible to perform a perturbative calculation. The
results are compared to recent theoretical predictions performed within the
framework of perturbative QCD.


title: Evidence for B+ -> omega l+ nu

abstract:
  We have searched for the decay B^+ -> omega l^+ nu in 78 fb^-1 of Y(4S) data
(85.0 million BBbar events) accumulated with the Belle detector. The final
state is fully reconstructed using the omega decay into pi^+ pi^- pi^0 and the
detector hermeticity to infer the neutrino momentum. The signal yield is
extracted by a two-dimensional fit to the lepton momentum and the invariant
p^i+ pi^- pi^0 mass. The result of the fit depends on the form factor model
assumed for the decay. Taking the average over three different models, 421 +/-
132 events are found in the data corresponding to a preliminary branching
fraction of (1.4 +/- 0.4(stat) +/- 0.2(syst) +/- 0.3(model)) * 10^-4.


title: Observation of eta_c^' Production in gamma-gamma Fusion at CLEO

abstract:
  We report on the observation of the eta_c^' (2 ^1S_0), the radial excitation
of eta_c (1 ^1S_0) ground state of charmonium, in the two-photon fusion
reaction gamma gamma to eta_c^' to K_S^0 K^{\pm} pi^{\mp} in 13.4 fb^{-1} of
CLEO II/II.V data and 9.2 fb^{-1} of CLEO III data. The data have been analyzed
to extract the eta_c^' resonance parameters.


title: Advances in Delta-md measurements

abstract:
  We report the current status of Delta-md measurements at B-factories. The
most recent world average is Delta-md = 0.502+-0.007 1/ps (1.4% accuracy). An
estimate of the errors for 500 1/fb data is also given.


title:
Highlights of the TEXONO Research Program on Neutrino and Astroparticle
  Physics

abstract:
  This article reviews the research program and efforts for the TEXONO
Collaboration on neutrino and astro-particle physics. The ``flagship'' program
is on reactor-based neutrino physics at the Kuo-Sheng (KS) Power Plant in
Taiwan. A limit on the neutrino magnetic moment of $\munuebar < 1.3 X 10^{-10}
\mub}$ at 90% confidence level was derived from measurements with a high purity
germanium detector. Other physics topics at KS, as well as the various R&D
program, are discussed


title: Results from DELPHI on the searches for SM and MSSM Neutral Higgs bosons

abstract:
  These final results from DELPHI searches for the Standard Model SM Higgs
boson, together with benchmark scans of the Minimal Supersymmetric Standard
Model MSSM neutral Higgs bosons, used data taken at centre-of-mass energies
between 200 and 209GeV with a total integrated luminosity of 224inv. pb.The
data from 192 to 202GeV are reanalysed with improved b-tagging for MSSM final
states decaying to four b-quarks. The 95% confidence level lower mass bound on
the Standard Model Higgs boson is 114.1GeV. Mass limits are also given on the
lightest scalar and pseudo-scalar Higgs bosons of the MSSM.


title: The scalar kappa from D+ -> K- pi+ pi+: Further Studies

abstract:
  We briefly review the recent results obtained by Fermilab experiment E791 on
the Dalitz plot analysis of the decay D+ -> K- pi+ pi+, where indication for a
light Kpi scalar resonance, the kappa, was found. We also present preliminary
studies providing further information on the phase behavior of the scalar
components at low mass, supporting the previous indication for the kappa.


title:
Event-by-Event Search for Charged Neutral Fluctuations in Pb - Pb
  Collisions at 158-A-GeV

abstract:
  Results from the analysis of data obtained from the WA98 experiment at the
CERN SPS have been presented. Some events have been filtered which show photon
excess in limited $\eta-\phi$ zones within the overlap region of the charged
particle and photon multiplicity detectors.


title: NuTeV Cross Section and Structure Function Measurements

abstract:
  The NuTeV experiment has obtained a unique high statistics sample of neutrino
and antineutrino interactions using its high-energy sign-selected beam.
Charged-current neutrino and anti-neutrino differential cross sections are
extracted. Neutrino-Iron structure functions, F_2(x,Q^2) and xF_3(x,Q^2), are
determined by fitting the y-dependence of the differential cross sections.
NuTeV has precise understanding of its hadron and muon energy scales, which
improves the systematic precision of this measurement.


title: A new method of measuring electric dipole moments in storage rings

abstract:
  A new highly sensitive method of looking for electric dipole moments of
charged particles in storage rings is described. The major systematic errors
inherent in the method are addressed and ways to minimize them are suggested.
It seems possible to measure the muon EDM to levels that test speculative
theories beyond the standard model.
