title: Experimental Status and Expectations Regarding Radiative Penguin Decays

abstract:
  Radiative penguin decays provide a hunting ground complementary to direct
searches for physics beyond the Standard Model. In the era of B-factories
copious production of B mesons permits precision measurements of radiative
penguin decays. We present herein the status of radiative penguin processes and
expectations at high luminosities, focusing on b -> s (d) gamma, b -> s l+ l-,
and b -> s \nu \nu bar modes


title: Performance of Multipurpose Detectors in Super B Factories

abstract:
  Based on background measurements at PEP II the impact of machine-related
backgrounds on individual components of multipurpose detectors is examined,
that operate in an asymmetric B factory at luminosities up to 10^{36} cm^{-2}
s^{-1}. Extrapolations of the BABAR experience suggests two feasible detector
designs.

abstract:
  The performance of present multipurpose detectors at high luminosities is
discussed.


title: Measurement of B0-anti-B0 Flavor Oscillations in Hadronic B0 Decays

abstract:
  Flavor oscillations of neutral $B$ mesons have been studied in $e^+e^-$
annihilation data collected with the BABAR detector at center-of-mass energies
near the $\Upsilon(4S)$ resonance. The data sample used for this purpose
consists of events in which one $B^0$ meson is reconstructed in a hadronic
decay mode, while the flavor of the recoiling $B^0$ is determined with a
tagging algorithm that exploits the correlation between the flavor of the heavy
quark and the charges of its decay products. From the time development of the
observed mixed and unmixed final states we determine the $B^0$-$\bar B^0$
oscillation frequency $\Delta m_d$ to be $0.516 \pm 0.016 ({stat}) \pm 0.010
({syst}) {\rm ps}^{-1}$.


title:
Measurement of the B0-anti-B0-Oscillation Frequency with Inclusive
  Dilepton Events

abstract:
  The $B^0$-$\bar B^0$ oscillation frequency has been measured with a sample of
23 million $\B\bar B$ pairs collected with the BABAR detector at the PEP-II
asymmetric B Factory at SLAC. In this sample, we select events in which both B
mesons decay semileptonically and use the charge of the leptons to identify the
flavor of each B meson. A simultaneous fit to the decay time difference
distributions for opposite- and same-sign dilepton events gives $\Delta m_d =
0.493 \pm 0.012{(stat)}\pm 0.009{(syst)}$ ps$^{-1}$.


title: CPT Results from KTeV

abstract:
  I present several preliminary measurements from KTeV of the fundamental
neutral kaon parameters, and their implications for CPT violation. A new limit
is given on the sidereal time dependence of $\phi_{+-}$. The results are based
on data collected in 1996-97.


title: Research Program of the TEXONO Collaboration: Status and Highlights

abstract:
  This article reviews the research program and efforts for the TEXONO
Collaboration among scientists from Taiwan and China. These include
reactor-based neutrino physics at the Kuo-Sheng Power Plant in Taiwan as well
as various R&D efforts related to the various experimental techniques in
neutrino and astro-particle physics.


title: BaBar B Decay Results

abstract:
  Data from the first run of the BaBar detector at the PEP II accelerator are
presented. Measurements of many rare B decay modes are now possible using the
large data sets currently being collected by BaBar. An overview of analysis
techniques and results on data collected in 2000 are described.


title: Search for lepton-flavor violation in e+p collisions at HERA

abstract:
  A search has been made for lepton-flavor-violating interactions, e+ p ->
mu/tau X, at a center-of-mass energy of 300 GeV with an integrated luminosity
of 47.7 pb^-1 using the ZEUS detector at HERA. No evidence was found for
lepton-flavor violation and constraints were derived on leptoquarks that could
mediate such interactions. Some of the constraints are also applicable to
lepton-flavor-violating processes mediated by squarks in R-parity-violating
supersymmetric models. In some cases involving heavy quarks and especially for
the tau channel, the ZEUS constraints are the most stringent published to date.


title:
Comparison of the Isolated Direct Photon Cross Sections in $p \bar p$
  Collisions at $\sqrt{s}=1.8$ TeV and $\sqrt{s}=0.63$ TeV

abstract:
  We have measured the cross sections $d^2\sigma/dP_T d\eta$ for production of
isolated direct photons in \pbarp collisions at two different center-of-mass
energies, 1.8 TeV and 0.63 TeV, using the Collider Detector at Fermilab (CDF).
The normalization of both data sets agree with the predictions of Quantum
Chromodynamics (QCD) for photon transverse momentum ($P_T$) of 25 GeV/c, but
the shapes versus photon $P_T$ do not. These shape differences lead to a
significant disagreement in the ratio of cross sections in the scaling variable
$x_T (\equiv 2P_T/\sqrt{s}$). This disagreement in the $x_T$ ratio is difficult
to explain with conventional theoretical uncertainties such as scale dependence
and parton distribution parameterizations.


title: Further Experimental Studies of Two-Body Radiative \Upsilon Decays

abstract:
  Continuing our studies of radiative Upsilon(1S) decays, we report on a search
for Upsilon to gamma eta and Upsilon to gamma f_{J}(2220) in 61.3 pb^{-1} of
e^{+}e^{-} data taken with the CLEO II detector at the Cornell Electron Storage
Ring. For the gamma eta search the three decays of the eta meson to
pi^{+}pi^{-}pi^{0}, pi^{0}pi^{0}pi^{0}, and gamma gamma were investigated. We
found no candidate events in the two (3\pi)^{0} modes and no significant excess
over expected backgrounds in the gamma gamma mode to set a limit on the
branching fraction of B(Upsilon to gamma eta) < 2.1 x 10^{-5} at 90% C.L. The
three charged two-body final states h h-bar (h = pi^{+}, K^{+}, p) were
investigated for f_{J}(2220) production, with one, one, and two events found,
respectively. Limits at 90% C.L. of B(\Upsilon to gamma f_{J}) x B(f_{J} to h
h-bar) ~ 1.5 x 10^{-5} have been set for each of these modes. We compare our
results to measurements of other radiative Upsilon decays, to measurements of
radiative J/psi decays, and to theoretical predictions.


title: Measurement of Dijet Cross Sections in Photoproduction at HERA

abstract:
  Dijet cross sections as functions of several jet observables are measured in
photoproduction using the H1 detector at HERA. The data sample comprises e^+p
data with an integrated luminosity of 34.9 pb^(-1). Jets are selected using the
inclusive k_T algorithm with a minimum transverse energy of 25 GeV for the
leading jet. The phase space covers longitudinal proton momentum fraction x_p
and photon longitudinal momentum fraction x_gamma in the ranges 0.05<x_p<0.6
and 0.1<x_gamma<1. The predictions of next-to-leading order perturbative QCD,
including recent photon and proton parton densities, are found to be compatible
with the data in a wide kinematical range.


title: Study of three-body charmless B decays

abstract:
  We report on a study of three-body charmless decays B+ => K+h+h-$ based on a
29.1 fb^{-1} data sample collected with the Belle detector. With no assumptions
on the intermediate mechanisms, the following three-body branching fractions
have been measured for the first time: Br(B+ => K+pi-pi+) =
(55.6\pm5.8\pm7.7)x10^{-6} and Br(B+ => K+K-K+) = (35.3\pm3.7\pm4.5)x10^{-6}.
We present the first observation of the decay B+ => f_0(980)K+ with a branching
fraction product of Br(B+ => f_0(980)K+)xBr(f_0(980) => \pi+\pi-)=
(9.6^{+2.5+1.5+3.4}_{-2.3-1.5-0.8})x10^{-6}. This is the first reported example
of a B meson decay to a scalar pseudoscalar final state. We also report the
first observation of B+ => K*(892)^0 pi+ decay with a branching fraction of
Br(B+ => K*(892)^0 pi+) = (19.4^{+4.2+2.1+3.5}_{-3.9-2.1-6.8})x10^{-6}.


title: Search for the Rare Decays B --> Kl^+l^- and B --> K^*l^+l^-

abstract:
  We present results from a search for the flavor-changing neutral current
decays $B\to K\ell^+\ell^-$ and $B\to K^*\ell^+\ell^-$, where $\ell^+\ell^-$ is
either an $e^+e^-$ or $\mu^+\mu^-$ pair. The data sample comprises $22.7\times
10^6$ $\Upsilon(4S)\to B\bar B$ decays collected with the BABAR detector at the
PEP-II $B$ Factory. We obtain the 90% C.L. upper limits ${\mathcal B}(B\to
K\ell^+\ell^-)< 0.50\times 10^{-6}$ and ${\mathcal B}(B\to
K^*\ell^+\ell^-)<2.9\times 10^{-6}$, close to Standard Model predictions for
these branching fractions. We have also obtained limits on the
lepton-family-violating decays $B\to Ke^{\pm}\mu^{\mp}$ and $B\to
K^{*}e^{\pm}\mu^{\mp}$.


title: Status report of the ANTARES project

abstract:
  The ANTARES project aims at the construction of an underwater neutrino
telescope at the scale of 0.1 km^2 2400 m deep in the Mediterranean Sea. After
a 4-year R&D program, the ANTARES project has entered the construction phase
which will be concluded by the end of 2004. The current status of the project
is reported.


title: A Test of CPT and Lorentz Invariance from Muonium Spectroscopy

abstract:
  Upon a suggestion of Kostelecky et al., we have performed a test of CPT and
Lorentz invariance from the microwave spectroscopy of muonium. New terms in
their standard model extension violating CPT and Lorentz symmetry would appear
as anti-correlated frequency shifts, oscillating at the earth's sidereal
frequency, in the two ground state hyperfine transitions involving muon spin
flip, $\nu_{12}$ and $\nu_{34}$, which were measured in a strong magnetic field
of 1.7 T. No such time dependence was observed in $\nu_{12}$ or $\nu_{34}$ at
the level of 20 Hz, limiting the size of some CPT and Lorentz violating
parameters with Planck scale sensitivity, and representing almost an order of
magnitude improvement over previous limits for the muon.


title: Search for Leptoquarks

abstract:
  This talk summarizes the status of Leptoquark searches performed at Tevatron,
LEP and HERA. Prospects for Leptoquark searches at future colliders at LHC and
TESLA are given.


title:
Inclusive Production of the omega and eta Mesons in Z Decays, and the
  Muonic Branching Ratio of the omega

abstract:
  The inclusive production of the omega(782) vector meson in hadronic Z decays
is measured and compared to model predictions. The analysis is based on 4
million hadronic Z decays recorded by the ALEPH detector between 1991 and 1995.
The production rate for x_p = p_meson/p_beam > 0.05 is measured in the omega ->
pi^+ pi^- pi^0 decay mode and found to be 0.585 +- 0.019_stat +- 0.033_sys per
event. Inclusive eta meson production is also measured in the same decay
channel for x_p > 0.10, obtaining 0.355 +- 0.011_stat +- 0.024_sys per event.
The branching ratio for omega -> mu^+ mu^- is investigated. A total of 18.1 +-
5.9 events are observed, from which the muonic branching ratio is measured for
the first time to be BR(omega -> mu^+ mu^-) = (9.0 +- 2.9_stat +-
1.1_sys)*10^-5.


title:
Search for R-Parity Violating Production of Single Sneutrinos in e+e-
  Collisions at sqrt(s) = 189-209GeV

abstract:
  A search for single sneutrino production under the assumption that R-parity
is violated via a single dominant $LL\bar{E}$ coupling is presented. This
search considers the process ${\rm e} \gamma {\smash{\mathop{\to}}}
\tilde{\nu}\ell$ and is performed using the data collected by the ALEPH
detector at centre-of-mass energies from 189 GeV up to 209 GeV corresponding to
an integrated luminosity of 637.1 $\mathrm{pb}^{-1}$. The numbers of observed
candidate events are in agreement with Standard Model expectations and 95%
confidence level upper limits on five of the $LL\bar{E}$ couplings are given as
a function of the assumed sneutrino mass.


title:
Final results of the searches for neutral Higgs bosons in e+e-
  collisions at sqrt(s) up to 209GeV

abstract:
  The final results of the ALEPH search for the Standard Model Higgs boson at
LEP, with data collected in the year 2000 at centre-of-mass energies up to 209
GeV, are presented. The changes with respect to the preceding publication are
described and a complete study of systematic effects is reported. The findings
of this final analysis confirm the preliminary results published in November
2000 shortly after the closing down of the LEP collider: a significant excess
of events is observed, consistent with the production of a $115 \Gcs$ Standard
Model Higgs boson. The final results of the searches for the neutral Higgs
bosons of the MSSM are also reported, in terms of limits on $\mh$, $\mA$ and
$\tanb$. Limits are also set on $\mh$ in the case of invisible decays.


title:
Semi-contained Interactions of Atmospheric Neutrinos in the MACRO
  Detector

abstract:
  Atmospheric neutrinos arise from the decay of particles (primarily pions,
muons and kaons) produced in the collision of high energy cosmic ray particles
with the atmosphere. The great distances traveled by atmospheric neutrinos
between their production and detection make them useful for studying neutrino
oscillations, the predicted phenomenon of massive neutrinos changing flavor in
flight. This thesis reports a study of atmospheric neutrinos interacting in the
MACRO detector. The results, though somewhat clouded by large theoretical
uncertainties, clearly rule out the no-oscillations hypothesis, and are
consistent with oscillations with the parameters preferred by other MACRO
neutrino analyses, as well as those of other experiments (most notably
Super-Kamiokande). Combining this analysis with another MACRO neutrino
analysis, some of the theoretical errors cancel, further constraining the
region of allowed oscillation parameters.


title: Use of Coulomb scattering for determining neutrino energies with MACRO

abstract:
  An estimate of the energy of neutrino-induced muons in MACRO is provided by a
multiple Coulomb scattering measurement. The MACRO original upward-muon data
sample has been subdivided according to the reconstructed muon energy. Data in
each subset are then compared with expected fluxes from atmospheric neutrinos.
The results are interpreted in terms of neutrino oscillations.


title:
Measurement of the ratio double/single muon events as a function of rock
  depth with MACRO

abstract:
  We report the measurement by the MACRO experiment of the ratio of double muon
events over single muon events as a function of rock depth. Particular
attention has been devoted to the analysis of high zenith angle events. Results
are compared to the expectation of a detailed simulation performed with
HEMAS-DPM Monte Carlo. No deviations with respect to ``standard physics''
predictions have been found.


abstract:
  This report summarises the activity of the E3 working group "Experimental
Approaches at Linear Colliders". The group was charged with examining
critically the physics case for a linear collider of energy of order 1 TeV as
well as the cases for higher energy machines, assessing the performance
requirements and exploring the viability of several special options. In
addition it was asked to identify the critical areas where R&D is required.


title:
A method for detecting $\nu_\tau$ appearance in the spectra of
  quasielastic CC events

abstract:
  A method for detecting the transition \omutau in long-baseline accelerator
experiments, that consists in comparing the far-to-near ratios of the spectra
of quasielastic CC events generated by high- and low-energy beams of muon
neutrinos, is proposed. The test may be accessible to big water Cherenkov
detectors and iron--scintillator calorimeters, and is limited by statistics
rather than systematics.


title:
A Study of Time-Dependent CP-Violating Asymmetries and Flavor
  Oscillations in Neutral B Decays at the Upsilon(4S)

abstract:
  We present a measurement of time-dependent CP-violating asymmetries in
neutral B meson decays collected with the BABAR detector at the PEP-II
asymmetric-energy B Factory at the Stanford Linear Accelerator Center. The data
sample consists of 29.7 ${\rm fb}^{-1}$ recorded at the $\Upsilon(4S)$
resonance and 3.9 ${\rm fb}^{-1}$ off-resonance. One of the neutral B mesons,
which are produced in pairs at the $\Upsilon(4S)$, is fully reconstructed in
the CP decay modes $J/\psi K^0_S$, $\psi(2S) K^0_S$, $\chi_{c1} K^0_S$, $J/\psi
K^{*0}$ ($K^{*0}\to K^0_S\pi^0$) and $J/\psi K^0_L$, or in flavor-eigenstate
modes involving $D^{(*)}\pi/\rho/a_1$ and $J/\psi K^{*0}$ ($K^{*0}\to
K^+\pi^-$). The flavor of the other neutral B meson is tagged at the time of
its decay, mainly with the charge of identified leptons and kaons. The proper
time elapsed between the decays is determined by measuring the distance between
the decay vertices. A maximum-likelihood fit to this flavor eigenstate sample
finds $\Delta m_d = 0.516\pm 0.016 {\rm (stat)} \pm 0.010 {\rm (syst)} {\rm
ps}^{-1}$. The value of the asymmetry amplitude $\sin2\beta$ is determined from
a simultaneous maximum-likelihood fit to the time-difference distribution of
the flavor-eigenstate sample and about 642 tagged $B^0$ decays in the
CP-eigenstate modes. We find $\sin2\beta=0.59\pm 0.14 {\rm (stat)} \pm 0.05
{\rm (syst)}$, demonstrating that CP violation exists in the neutral B meson
system. (abridged)


title: The Majorana Ge-76 Double-Beta Decay Project

abstract:
  The Majorana Experiment is a next-generation Ge-76 double-beta decay search.
It will employ 500 kg of Ge, isotopically enriched to 86% in Ge-76, in the form
of 200 detectors in a close-packed array for high granularity. Each crystal
will be electronically segmented, with each region fitted with pulse-shape
analysis electronics. A half-life sensitivity is predicted of 4.2e27 y or
<m_nu> < 0.02-0.07 eV, depending on the nuclear matrix elements used to
interpret the data.


title:
Searches for neutral Higgs bosons in e+e- collisions from sqrt(s) =
  191.6 to 201.7 GeV

abstract:
  Neutral Higgs bosons of the Standard Model (SM) and the Minimal
Supersymmetric Standard Model (MSSM) were searched for in the data collected in
1999 by the DELPHI experiment at centre-of-mass energies between 191.6 and
201.7 GeV with a total integrated luminosity of 228 pb^{-1}. These analyses, in
combination with our results at lower energies, set 95% confidence level lower
mass bounds on the Standard Model Higgs boson (107.3 GeV/c^2) and on the
lightest neutral scalar (85.9 GeV/c^2) and neutral pseudoscalar (86.5 GeV/c^2)
Higgs bosons in representative scans of the MSSM parameter space. An extended
scan of the MSSM parameter space was also performed to test the robustness of
these limits.


title:
Search for Charged Higgs Bosons in e+e- Collisions at sqrt(s)=189-202
  GeV

abstract:
  A search for pair-produced charged Higgs bosons was performed in the high
energy data collected by the DELPHI detector at LEP II at centre-of-mass
energies from 189 GeV to 202 GeV. The three different final states, \tau \nu
\tau \nu, c \bar s \bar c s and c \bar s \tau \nu were considered. New methods
were applied to reject wrong hadronic jet pairings and for the tau
identification, where a discriminator based on tau polarisation and polar
angles was used. No excess of data compared to the expected Standard Model
processes was observed and the existence of a charged Higgs boson with mass
lower than 71.5 GeV/c^2 is excluded at the 95% confidence level.


title: Leptonic decays of the Ds meson

abstract:
  The purely leptonic decays Ds -> tau nu and Ds -> mu nu are studied in a
sample of four million hadronic Z decays collected with the ALEPH detector at
the LEP e+e- collider from 1991 to 1995. The branching fractions are extracted
from a combination of two analyses, one optimized to select Ds -> tau nu decays
with tau -> e nu nubar or mu nu nubar, and the other optimized for Ds-> mu nu
decays. The results are used to evaluate the Ds decay constant, within the
Standard Model: fDs = [285 +- 19(stat) +- 40 (syst)] MeV


title:
Strange Particle Production in p+p, p+Pb and Pb+Pb Interactions from
  NA49

abstract:
  Recent NA49 results on Lambda, Antilambda, Xi- and Antixi+ production in
minimum bias p+p and centrality selected p+Pb collisions at 158 GeV/c, and the
results on Lambda, Antilambda, K+ and K- production in central Pb+Pb collisions
at 40, 80 and 158 A GeV are discussed and compared with other available data.
By comparing the energy dependence of Lambda and Antilambda production at
mid-rapidity a striking similarity is observed between p+p and A+A data. This
is also seen in the energy dependence of the Lambda/pi ratio. K+/pi at
mid-rapidity is affected in a similar way, due to the associated production of
K+ together with Lambda particles. The observed yields increase faster than the
number of wounded nucleons when comparing p+Pb to p+p. As already observed in
A+A collisions, the increase is larger for multistrange than for strange
baryons and for baryons than for anti-baryons.


title: Rare K decay: results and prospects

abstract:
  Recent results on rare kaon decays are reviewed and prospects for future
experiments are discussed.


title: High Energy Two-Photon Interactions at the LHC

abstract:
  Two-photon events at the LHC are characterized by the protons scattered at
very small angles and the particles centrally produced via the photon-photon
fusion. To select these events from the huge samples of generic pp interactions
a detection of the scattered protons, or tagging two-photon interactions is
necessary. It requires installation of the high-resolution position-sensitive
detectors close to the proton beam and far from the interaction point.
Efficient measurement of the forward-scattered protons will open a new field of
studying high-energy photon-photon interactions at remarkable luminosity,
reaching 1% of that in pp collisions. In this paper a few aspects of tagging
two-photon interactions as well as several most exciting topics in the
high-energy two-photon physics at the LHC are presented.


title:
A Monitor of the Focusing Strength of Plasma Lenses Using MeV
  Synchrotron Radiation

abstract:
  The focusing strength of plasma lenses used with high energy electron or
positron beams can give rise to synchrotron radiation with critical energies in
the MeV range. A method is described for measuring the characteristic energy of
this radiation as a way of monitoring the strength of the focus. The principle
has been implemented in a plasma lens experiment with a 28.5 GeV positron beam.


title: Search for Exotics and Extra Dimensions at LEP

abstract:
  Results from various searches for new physical phenomena performed by the
four LEP experiments are summarised. Topics presented include the search for
contact interactions, a Z' boson, leptoquarks, excited leptons, technicolour
and gravity in extra dimensions.


title: Evidence for hadronic deconfinement in $\bar{p}$-p collisions at 1.8 TeV

abstract:
  We have measured deconfined hadronic volumes, $4.4 < V < 13.0$ fm$^{3}$,
produced by a one dimensional (1D) expansion. These volumes are directly
proportional to the charged particle pseudorapidity densities $6.75 <
dN_{c}/d\eta < 20.2$. The hadronization temperature is $T = 179.5 \pm 5$ (syst)
MeV. Using Bjorken's 1D model,the hadronization energy density is $\epsilon_{F}
= 1.10 \pm 0.26$ (stat) GeV/fm$^{3}$ corresponding to an excitation of $24.8
\pm 6.2$ (stat) quark-gluon degrees of freedom.


title:
On measurements of the energy and polarization distributions of
  high-energy gamma-beams

abstract:
  A possibility to measure the energy and polarization distributions of high
intensity gamma-beams is considered. This possibility is based on measurements
of the number of electron-pozitron pairs in such media as laser waves and
single crystals. The method may be useful for future gamma-gamma and e-gamma
colliders.


title: Atmospheric neutrino oscillations

abstract:
  The recent results from the Soudan 2, MACRO and SuperKamiokande experiments
on atmospheric neutrino oscillations are summarized and discussed. Some
features of possible future atmospheric neutrino experiments are presented.


title: Electron polarization measurement using a Fabry-Perot cavity at HERA

abstract:
  A new Compton longitudinal polarimeter currently under construction for HERA
is presented. The key component of the polarimeter is a Fabry-Perot cavity
located around the electron beam pipe. With such an optical cavity, a
continuous laser power equivalent to 5 kW, much higher than those commercially
available, can be achieved, leading to one backscattered photon per bunch
crossing. This ``few-photon mode'' will allow a very precise determination of
the calorimeter response with little systematic uncertainty. The electron
polarization measurement at the per mill level is expected.


title: Hot Topics in Ultra-Peripheral Collisions

abstract:
  Ultra-peripheral collisions of relativistic heavy ions involve long-ranged
electromagnetic interactions at impact parameters too large for hadronic
interactions to occur. The nuclear charges are large; with the coherent
enhancement, the cross sections are also large. Many types of photonuclear and
purely electromagnetic interactions are possible. We present here an
introduction to ultra-peripheral collisions, and present four of the most
compelling physics topics. This note developed from a discussion at a workshop
on ``Electromagnetic Probes of Fundamental Physics,'' in Erice, Italy, Oct.
16-21, 2001.


title: Anomalous couplings at LEP2

abstract:
  In its second phase, LEP has allowed to study four fermion processes never
observed before. Results are presented on the charged triple gauge boson
couplings (TGC) from the W-pair, Single W and Single gamma production. The
anomalous quartic gauge couplings (QGC) are constrained using production of
WWgamma, nunubargammagamma and Zgammagamma final states. Finally, limits on the
neutral anomalous gauge couplings (NGC) using the Zgamma and ZZ production
processes are also reported. All results are consistent with the Standard Model
expectations.


title: Polarized Structure Functions and Spin Physics

abstract:
  Recent progress in the field of spin physics of high energy particle
interactions is reviewed with particular emphasis on the spin structure
functions as measured in polarized deep inelastic lepton-nucleon scattering
(DIS). New measurements are presented to obtain more direct information on the
composition of the nucleon angular momentum, with results from semi-inclusive
DIS accessing flavour-separated parton distribution functions (PDF) and with
first data from hard exclusive reactions which may be interpreted in terms of
recently developed generalizations of parton distribution functions (GPD).
Finally, experimental prospects are outlined which will lead to a further
development of the virtues of QCD phenomenology of the spin structure of the
nucleon.


title:
Search for the decay $K^+\to \pi^+ \nu \bar\nu$ in the momentum region
  $P_\pi < 195 {\rm ~MeV/c}$

abstract:
  We have searched for the decay $K^+ \to \pi^+ \nu \bar\nu$ in the kinematic
region with pion momentum below the $K^+ \to \pi^+ \pi^0$ peak. One event was
observed, consistent with the background estimate of $0.73\pm 0.18$. This
implies an upper limit on $B(K^+ \to \pi^+ \nu \bar\nu)< 4.2\times 10^{-9}$
(90% C.L.), consistent with the recently measured branching ratio of
$(1.57^{+1.75}_{-0.82}) \times 10^{-10}$, obtained using the standard model
spectrum and the kinematic region above the $K^+ \to \pi^+ \pi^0$ peak. The
same data were used to search for $K^+ \to \pi^+ X^0$, where $X^0$ is a weakly
interacting neutral particle or system of particles with $150 < M_{X^0} < 250
{\rm ~MeV/c^2}$.


title: A Cryogenic Underground Observatory for Rare Events: Cuore, an Update

abstract:
  CUORE is a proposed tightly packed array of 1000 TeO_{2} bolometers, each
being a cube 5 cm on a side with a mass of 750 gms. The array consists of 25
vertical towers, arranged in a square, of 5 towers by 5 towers, each containing
10 layers of 4 crystals. The design of the detector is optimized for ultralow-
background searches for neutrinoless double beta decay of ^{130}Te (33.8%
abundance), cold dark matter, solar axions, and rare nuclear decays. A
preliminary experiment involving 20 crystals of various sizes (MIBETA) has been
completed, and a single CUORE tower is being constructed as a smaller scale
experiment called CUORICINO. The expected performance and sensitivity, based on
Monte Carlo simulations and extrapolations of present results, are reported.


title:
Fragmentation cross sections of 158 A GeV Pb ions in various targets
  measured with CR39 nuclear track detectors

abstract:
  We report the measurement of the fragmentation cross sections in high-energy
nucleus-nucleus collisions using the 158 A GeV Pb beam from the CERN-SPS. The
fragments have charges changed from that of the incident projectile nucleus by
$\Delta Z=Z_{Pb}-Z_{frag}$, with 8 <\Delta Z <75. The targets range from
polyethylene to lead. Charge identification is made with CR39 nuclear track
detectors, measured with an automatic image analyzer system. The measured
fragmentation cross sections are parameterized with an empirical relation in
terms of the atomic mass of the target, and of the charge of the final
fragment.


title:
Study of the process $e^+e^- \to \pi^+\pi^-\pi^0$ in the energy region
  $\sqrt[]{s}$ from 0.98 to 1.38 GeV.}

abstract:
  The cross section of the process $e^+e^-\to \pi^+\pi^-\pi^0$ was measured in
the Spherical Neutral Detector experiment at the VEPP-2M collider in the energy
region $\sqrt[]{s} = 980 \div 1380$ MeV. The measured cross section, together
with the $e^+e^-\to \pi^+\pi^-\pi^0$ and $\omega\pi^+\pi^-$ cross sections
obtained in other experiments, was analyzed in the framework of the generalized
vector meson dominance model. It was found that the experimental data can be
described by a sum of $\omega$, $\phi$ mesons and two $\omega^\prime$ and
$\omega^{\prime\prime}$ resonances contributions, with masses
$m_{\omega^\prime}\sim 1490$,$m_{\omega^{\prime\prime}}\sim 1790$ MeV and
widths $\Gamma_{\omega^\prime}\sim 1210$, $\Gamma_{\omega^{\prime\prime}}\sim
560$ MeV. The analysis of the $\pi^+\pi^-$ invariant mass spectra in the energy
region $\sqrt[]{s}$ from 1100 to 1380 MeV has shown that for their
descriptionone should take into account the
$e^+e^-\to\omega\pi^0\to\pi^+\pi^-\pi^0$ mechanism also. The phase between the
amplitudes corresponding to the $e^+e^-\to\omega\pi$ and $e^+e^-\to\rho\pi$
intermediate states was measured for the first time. The value of the phase is
close to zero and depends on energy.

Measurement of Ds+ and Ds*+ Production in B Meson Decays and from
  Continuum e+e- Annihilation at sqrt{s}=10.6 GeV

abstract:
  New measurements of Ds+ and Ds*+ meson production rates from B decays and
from qqbar continuum events near the Y(4S) resonance are presented. Using 20.8
fb-1 of data on the Y(4S) resonance and 2.6 fb-1 off resonance, we find the
inclusive branching fractions BR(B --> Ds+ X) = (10.93+/-0.19+/-0.58+/-2.73)%
and BR(B --> Ds*+ X) = (7.9+/-0.8+/-0.7+/-2.0)%, where the first error is
statistical, the second is systematic, and the third is due to the Ds+ --> phi
pi+ branching fraction uncertainty. The branching fractions SumBR(B --> Ds(*)+
Dbar(*)) = (5.07+/-0.14+/-0.30+/-1.27)% and SumBR(B --> Ds*+ Dbar(*)) =
(4.1+/-0.2+/-0.4+/-1.0)% are determined from the Ds(*)+ momentum spectra.


title: Search For New Particles at HERA

abstract:
  Recent results on searches for physics beyond the Standard Model obtained by
the H1 and ZEUS experiments are reported here. After a brief introduction to
the HERA collider, indirect searches for contact interactions and
extra-dimensions are presented as well as direct searches for new physics
including leptoquarks, lepton-flavour violation, squarks produced by R-parity
violation and excited fermions. New results from isolated lepton events and
single top searches are also presented. Finally the future prospects of HERA-2
are shown.


title: Exclusive photoproduction of J/psi mesons at HERA

abstract:
  The exclusive photoproduction of J/psi mesons, gamma p->J/psi p, has been
studied in ep collisions with the ZEUS detector at HERA, in the kinematic range
20<W<290 GeV, where W is the photon-proton centre-of-mass energy. The J/psi
mesons were reconstructed in the muon and the electron decay channels using
integrated luminosities of 38 pb^-1 and 55 pb^-1, respectively.
  The helicity structure of J/psi production shows that the hypothesis of
s-channel helicity conservation is satisfied at the two standard-deviation
level. The total cross section and the differential cross-section dsigma/dt,
where t is the squared four-momentum transfer at the proton vertex, are
presented as a function of W, for |t|<1.8 GeV^2. The t distribution exhibits an
exponential shape with a slope parameter increasing logarithmically with W with
a value b=4.15 \pm 0.05 (stat.)^{+0.30}_{-0.18} (syst.) GeV^-2 at W=90 GeV.
  The effective parameters of the Pomeron trajectory are alphapom(0) = 1.200
\pm 0.009(stat.)^{+0.004}_{-0.010}(syst.) and alphappom= 0.115 \pm
0.018(stat.)^{+0.008}_{-0.015}(syst.) GeV^-2.


title: Main Parameters of the Linac-Ring Type Phi, Charm and Tau Factories

abstract:
  Parameters for linac-ring type e^{-}e^{+} colliders with sqrt(s)=1020 MeV
(phi factory), 3770 MeV (charm factory) and 4.2 GeV (tau factory) are
discussed. It is shown that luminosities of the order of 10^{34} cm^{-2}s^{-1}
can be achieved.


title: Future Possibilities for Lepton-Hadron Collider Physics and Detectors

abstract:
  We have considered the physics opportunities of future lepton-hadron
colliders and how these opportunities might be realized in a possible polarized
eRHIC facility and an e-p collider as part of a staged or final version VLHC.
We evaluated the physics priorities based on experience at HERA and, using
simulated data for e-p collisions with sqrt(s) > 1 TeV, showed how detector
designs would be impacted by the physics.


title: Particle Correlations at LEP

abstract:
  Particle correlations are extensively studied to obtain information about the
dynamics of hadron production. From 1989 to 2000 the four LEP collaborations
recorded more than 16 million hadronic Z0 decays and several thousand W+W-
events. In Z0 decays, two-particle correlations were analysed in detail to
study Bose-Einstein and Fermi-Dirac correlations for various particle species.
In fully-hadronic W+W- decays, particle correlations were used to study whether
the two W bosons decay independently. A review of selected results is
presented.


title:
Report of Snowmass 2001 Working Group E2 : Electron-positron Colliders
  from the $\phi$ to the Z

abstract:
  We report on the status and plans of experiments now running or proposed for
electron-positron colliders at energies between the $\phi$ and the Z. The
$e^{+}e^{-}$ B and charm factories we considered were PEP-II/BABAR, KEKB/Belle,
superKEK, SuperBABAR, and CESR-c/CLEO-c. We reviewed the programs at the $\phi$
factory at Frascati and the proposed PEP-N facility at Stanford Linear
Accelerator Center. We studied the prospects for B physics with a dedicated
linear collider Z factory, associated with the TESLA high energy linear
collider. In all cases, we compared the physics reach of these facilities with
that of alternative experiments at hadron colliders or fixed target facilities.


title: New Results on ATLAS Pixel Opto-Link

abstract:
  We present new results on the optical link for the pixel detector of the
ATLAS experiment. An optical package of novel design has been developed for the
opto-link. The design is based on a simple connector-type concept and is made
of radiation-hard material. The receiver (DORIC) and transmitter (VDC) chips
have been designed. The prototype results using the 0.8 and 0.25 um
technologies are presented.


title: Tracking Performance of the HERA-B Outer Tracker PC Chambers

abstract:
  The paper was withdrawn by the authors since it has not been reviewed and
approved by an official body within the collaboration.


title: A High Statistics Measurement of the Lambdac+ Lifetime

abstract:
  A high statistics measurement of the Lambdac+ lifetime from the Fermilab
fixed-target FOCUS photoproduction experiment is presented. We describe the
analysis technique with particular attention to the determination of the
systematic uncertainty. The measured value of 204.6 +/- 3.4 (stat.) +/- 2.5
(syst.) fs from 8034 +/- 122 Lambdac -> pKpi decays represents a significant
improvement over the present world average.


title: Simulation of a RICH Detector for the CKM Experiment

abstract:
  We will present here the simulations of RICH detectors which will be used in
the CKM experiment. We will verify their performance, critical to the
experiment.


title: Resonances in Lambda_c+ to p K- pi+

abstract:
  We report very preliminary results of a Dalitz-plot analysis of Lambda_c+ in
the decay to p K- pi+ with the helicity formalism. We used the data from the
fixed target experiment SELEX (E781) in Fermilab. We report about
branching-ratios of the resonant states involved, and a possible initial state
polarization.


title: The calorimetry at the future e+ e- linear collider

abstract:
  The physics programme for a coming electron linear collider is dominated by
events with final states containing many jets. We develop in this paper the
opinion that the best approach is to optimise the independent measurement of
the tracks in the tracker, the photons in the electromagnetic calorimeter and
the neutral hadrons in the camorimetry, together with a good lepton
identification. This can be achieved with a high granularity calorimetry
providing particle separation, through an efficient energy flow algorithm.


title:
Measurement of the B0 Lifetime with Partially Reconstructed B0 --> D*-
  l+ nu Decays

abstract:
  The B0 lifetime has been measured with a sample of 23 million BBbar pairs
collected by the BaBar detector at the PEP-II e+e- storage ring during 1999 and
2000. Events from the semileptonic decay B0 --> D*- l+ nu have been selected
with a partial reconstruction method in which only the charged lepton and the
slow pion from the D*- --> D0bar pi- decay are reconstructed. The result is
tau_B0 = 1.529+/-0.012 (stat) +/- 0.029 (syst) ps.


title:
Study of single muons with the Large Volume Detector at Gran Sasso
  Laboratory

abstract:
  The present study is based on the sample of about 3 mln single muons observed
by LVD at underground Gran Sasso Laboratory during 36500 live hours from June
1992 to February 1998. We have measured the muon intensity at slant depths from
3 km w.e. to 20 km w.e. Most events are high energy downward muons produced by
meson decay in the atmosphere. The analysis of these muons has revealed the
power index of pion and kaon spectrum: 2.76 \pm 0.05. The reminders are
horizontal muons produced by the neutrino interactions in the rock surrounding
LVD. The value of this flux is obtained. The results are compared with Monte
Carlo simulations and the world data.


title: e^+e^- Physics at LEP and a Future Linear Collider

abstract:
  A summary of results obtained from e^+e^- annihilations at LEP is given. The
precision measurements around the Z resonance, the results from charged gauge
boson production and searches for new particles are reviewed. Particular
emphasis is devoted to the Higgs boson. The prospects of an e^+e^- linear
collider in the energy range of about 1 TeV are discussed.


abstract:
  Sub-mm tests of the gravitational inverse-square law are interesting from
several quite different perspectives. This paper discusses work by the Eot-Wash
group performed since the publication of our initial result in February 2001.
We find no evidence for short-range Yukawa interactions. Our results provide an
upper limit of 200 micrometers on the size of the largest ``extra'' dimension,
and for the unification scenario with 2 large extra dimensions, set an upper
limit of 150 micrometers on the size of those dimensions.


title:
Precise Measurement of B Meson Lifetimes with Hadronic Decay Final
  States

abstract:
  The lifetimes of the B0bar and B- mesons are extracted from 29.1/fb of data
collected with the Belle detector at the KEK B-factory. A fit to the decay
length differences of neutral and charged B meson pairs, measured in events
where one of the B mesons is fully reconstructed in several hadronic modes,
yields tau_B0bar = 1.554 +/- 0.030(stat) +/- 0.019(syst) ps, tau_B- = 1.695 +/-
0.026(stat) +/- 0.015(syst) ps, and tau_B-/tau_B0bar = 1.091 +/- 0.023(stat)
+/- 0.014(syst).


title: Results of time evolution analyses of B-decays at Belle

abstract:
  We report results of proper-time evolution analyses of B decays at Belle,
based on a 29.1/fb data sample recorded at the Upsilon (4S) resonance. These
results include measurements of sin2phi_1, the lifetime of B-mesons, and the
mass-difference between two mass eigenstates of the B^0-B^0-bar system
(Delta-m_d). Delta-m_d is measured using three different methods: fully
reconstructed hadronic modes, a fully reconstructed semi-leptonic mode, and a
partially reconstructed D*+ pi- mode.


title: Search for gammagamma -> eta_b in e+e- collisions at LEP2

abstract:
  A search for the pseudoscalar meson eta_b is performed in two-photon
interactions at LEP~2 with an integrated luminosity of 699 pb^-1 collected at
e+e- centre-of-mass energies from 181 GeV to 209 GeV. One candidate event is
found in the six-charged-particle final state and none in the
four-charged-particle final state, in agreement with the total expected
background of about one event. Upper limits of Gamma_gammagamma(eta_b) *
BR(eta_b -> 4 charged particles) < 48 eV Gamma_gammagamma(eta_b) * BR(eta_b ->
6 charged particles) < 132 eV are obtained at 95% confidence level, which
correspond to 95% confidence level upper limits of 9.0% and 25% on these
branching ratios.


title: New CLEO II Results on Charm Hadron Decays

abstract:
  We present new results on charm hadron decays from the CLEO II experiment.
The D*+ width is measured for the first time, Gamma(D*+) = 96 +- 4 +- 22 keV.
The semileptonic decay branching fractions are determined to be B(D+ --> Kbar*0
e+ nu_e) = (6.7 +- 0.4 +- 0.5 +- 0.4)% and B(D+ --> Kbar*0 mu+ nu_mu) = (6.5 +-
0.9 +- 0.5 +- 0.4)%. We observe evidence for Omega_c --> Omega- e+ nu_e and
measure the product of the branching fraction and cross section, B(Omega_c -->
Omega- e+ nu_e) x sigma(e+e- --> Omega_cX) = 42.2 +- 14.1 +- 11.9 fb. Within
the framework of Heavy Quark Effective Theory, we measure in the decay
Lambda+_c --> Lambda e+ nu_e the form factor ratio, R = f_2/f_1 = -0.31 +- 0.06
+- 0.06. This provides strong evidence that the form factor f_2 describing spin
interactionof the s quark is non-zero. The Xi+_c lifetime is measured to be 503
+- 47 +- 18 fs. The results on branching fractions, cross section, and form
factor ratio are preliminary.


title:
Including Systematic Uncertainties in Confidence Interval Construction
  for Poisson Statistics

abstract:
  One way to incorporate systematic uncertainties into the calculation of
confidence intervals is by integrating over probability density functions
parametrizing the uncertainties. In this note we present a development of this
method which takes into account uncertainties in the prediction of background
processes, uncertainties in the signal detection efficiency and background
efficiency and allows for a correlation between the signal and background
detection efficiencies. We implement this method with the Feldman & Cousins
unified approach with and without conditioning. We present studies of coverage
for the Feldman & Cousins and Neyman ordering schemes. In particular, we
present two different types of coverage tests for the case where systematic
uncertainties are included. To illustrate the method we show the relative
effect of including systematic uncertainties the case of dark matter search as
performed by modern neutrino tel escopes.


title: Measurement of the electron electric dipole moment using YbF molecules

abstract:
  The most sensitive measurements of the electron electric dipole moment d_e
have previously been made using heavy atoms. Heavy polar molecules offer a
greater sensitivity to d_e because the interaction energy to be measured is
typically 10^3 times larger than in a heavy atom. We report the first
measurement of this kind, for which we have used the molecule YbF. Together,
the large interaction energy and the strong tensor polarizability of the
molecule make our experiment essentially free of the systematic errors that
currently limit d_e measurements in atoms. Our first result d_e = (- 0.2 \pm
3.2) x 10^-26 e.cm is less sensitive than the best atom measurement, but is
limited only by counting statistics and demonstrates the power of the method.


title:
Scanning Lidar Based Atmospheric Monitoring for Fluorescent Detectors of
  Cosmic Showers

abstract:
  Measurements of the cosmic-ray air-shower fluorescence at extreme energies
require precise knowledge of atmospheric conditions. The absolute calibration
of the cosmic-ray energy depends on the absorption of fluorescence light
between its origin and point of its detection. To reconstruct basic atmospheric
parameters we review a novel analysis method based on two- and multi-angle
measurements performed by the scanning backscatter lidar system. Applied
inversion methods, optical depth, absorption and backscatter coefficient, as
well as other parameters that enter the lidar equation are discussed in
connection to the attenuation of the light traveling from shower to
fluorescence detector.


title: A Measurement of the KL Charge Asymmetry

abstract:
  We present a measurement of the charge asymmetry $\delta_L$ in the mode $K_L
\to \pi^{\pm}e^{\mp}\nu$ based on 298 million analyzed decays. We measure a
value of $\delta_L = (3322 \pm 58(stat) \pm 47(sys))\cdot 10^{-6}$, in good
agreement with previous measurements and 2.4 times more precise than the
current best published result. The result is used to place more stringent
limits on CPT and $\Delta S = \Delta Q$ violation in the neutral kaon system.


title: Observation of $B^{\pm}\to p \bar{p} K^{\pm}$

abstract:
  We report the observation of the decay mode $B^{\pm}\to p \bar{p} K^{\pm}$
based on an analysis of 29.4 fb$^{-1}$ of data collected by the Belle detector
at KEKB. This is the first example of a $b\to s$ transition with baryons in the
final state. The $p \bar{p}$ mass spectrum in this decay is inconsistent with
phase space and is peaked at low mass. The branching fraction for this decay is
measured to be ${\cal B}(B^{\pm}\to p \bar{p} K^{\pm})
  =(4.3^{+1.1}_{-0.9}({\rm stat})\pm 0.5({\rm syst}))\times 10^{-6}.$ We also
report upper limits for the decays $B^0\to p \bar{p} K_S$ and $B^{\pm}\to p
\bar{p} \pi^{\pm}$.


title: Comment on "Evidence for Neutrinoless Double Beta Decay"

abstract:
  We comment on the recent claim for the experimental observation of
neutrinoless double-beta decay. We discuss several limitations in the analysis
provided in that paper and conclude that there is no basis for the presented
claim.


title: Improved Measurement of |V_ub| with Inclusive Semileptonic B Decays

abstract:
  We report a new measurement of the CKM parameter V_ub made with a sample of
9.7 million B B-bar events collected with the CLEO II detector. Using Heavy
Quark theory, we combine the observed yield of leptons from semileptonic B
decay in the end-point momentum interval 2.2-2.6 GeV/c with recent CLEO II data
on B --> X_s gamma to find |V_ub| = (4.08 +/- 0.34 +/- 0.44 +/- 0.16 +/- 0.24)
x 10^-3, where the first two uncertainties are experimental and the last two
are from theory.


title: A Unique Oscillation Solution to the Solar Neutrino Problem?

abstract:
  A global two-neutrino oscillation fit combining Super-Kamiokande solar
neutrino data with the solar neutrino rates measured by Homestake, Gallex/GNO,
SAGE and SNO prefers a single allowed area, the Large Mixing Angle solution, at
about 95% confidence level. The mass^2 difference between the two mass
eigenstates is Delta m^2 approx 3-25 x 10^-5 eV^2, the mixing angle theta is
tan^2 theta approx 0.21-0.67.


title: Solar and Reactor Neutrinos: Upcoming Experiments and Future Projects

abstract:
  Sub-MeV solar neutrino experiments and long-baseline reactor oscillation
experiments toe the cutting edge of neutrino research. The upcoming experiments
KamLAND and BOREXINO, currently in their startup and final construction phase
respectively, will provide essential information on neutrino properties as well
as on solar physics. Future projects, at present under development, will
measure the primary solar neutrino fluxes via electron scattering and neutrino
capture in real time. High precision data for lepton mixing as well as for
stellar evolution theory will become available in the future. This paper aims
to give an overview of the upcoming experiments and of the projects under
development.


title: Rare Hadronic and Radiative Penguin B Decays at BaBar

abstract:
  We report recent results in the study of rare hadronic and radiative penguin
decays of B mesons. These results are based on a sample of 23 million B B-bar
pairs collected by the BaBar Collaboration at the SLAC PEP-II e+e- B Factory.


title: Results from high energy accelerators

abstract:
  We review some of the recent experimental results obtained at high-energy
colliders with emphasis on LEP and SLC results.


title: The BNL Muon Anomalous Magnetic Moment Measurement

abstract:
  The E821 experiment at Brookhaven National Laboratory is designed to measure
the muon magnetic anomaly, a_mu, to an ultimate precision of 0.4 parts per
million (ppm). Because theory can predict a_mu to 0.6 ppm, and ongoing efforts
aim to reduce this uncertainty, the comparison represents an important and
sensitive test of new physics. At the time of this Workshop, the reported
experimental result from the 1999 running period achieved a_mu = 11 659
202(14)(6)x 10^-10 (1.3 ppm) and differed from the most precise theory
evaluation by 2.6 standard deviations. Considerable additional data has already
been obtained in 2000 and 2001 and the analysis of this data is proceeding
well. Intense theoretical activity has also taken place ranging from
suggestions of the new physics which could account for the deviation to careful
re-examination of the standard model contributions themselves. Recently, a
re-evaluation of the pion pole contribution to the hadronic light-by-light
process exposed a sign error in earlier studies used in the standard theory.
With this correction incorporated, experiment and theory disagree by a modest
1.6 standard deviations.


title:
Study of Multiphoton Final States and Tests of QED in e+e- collisions at
  \root(s) up to 209 GeV

abstract:
  The process e+ e- -> n gamma with n>=2 is studied at centre-of-mass energies
ranging from \root(s)=192 to 208 GeV. The data sample corresponds to a total
integrated luminosity of 427 1/pb. The total and differential cross sections
are found to be in agreement with the QED expectations. Using all the data
collected with the L3 detector above the Z pole, limits on deviations from QED,
excited electrons, contact interactions, extra space dimensions and excited
spin-3/2 leptons are set.


title:
The Igex 76ge Neutrinoless Double-Beta Decay Experiment: Prospects for
  Next Generation Experiments

abstract:
  The International Germanium Experiment (IGEX) has analyzed 117 mole yr of
76Ge data from its isotopically enriched (86% 76Ge) germanium detectors.
Applying pulse-shape discrimination (PSD) to the more recent data, the lower
bound on the half-life for neutrinoless double-beta decay of 76Ge is:
$T_{1/2}(0\nu)> 1.57 \times 10^{25}$ yr (90% C.L.). This corresponds to an
upper bound in the Majorana neutrino mass parameter,$<m_{\nu}>$, between 0.33
eV and 1.35 eV, depending on the choice of theoretical nuclear matrix elements
used in the analysis.


title: Observation of Mixing-induced CP Violation in the Neutral B Meson System

abstract:
  This report describes an observation of mixing-induced CP violation and a
measurement of the CP violation parameter, sin(2phi_1), with the Belle detector
at the KEKB asymmetric e+e- collider. Using a data sample of 29.1 fb-1 recorded
on the Upsilon(4S) resonance that contains 31.3 million BBbar pairs, we
reconstruct decays of neutral B mesons to the following CP eigenstates: J/psi
K_S^0, psi(2S) K_S^0, chi_c1 K_S^0, eta_c K_S^0, J/psi K_L^0 and J/psi K^*0.
The flavor of the accompanying B meson is identified by combining information
from primary and secondary leptons, K+/- mesons, lambda baryons, slow and fast
pions. The proper-time interval between the two B meson decays is determined
from the distance between the two decay vertices measured with a silicon vertex
detector. The result sin(2phi_1) = 0.99 +/- 0.14(stat) +/- 0.06(syst) is
obtained by applying a maximum likelihood fit to the 1137 candidate events. We
conclude that there is large CP violation in the neutral B meson system. A zero
value for sin(2phi_1) is ruled out by more than six standard deviations.


title: Observation of chi_c2 Production in B-meson Decay

abstract:
  We report the first observation of chi_c2 production in B-meson decays. We
find an inclusive B -> chi_c2 X branching fraction of (1.80^{+0.23}_{-0.28}+/-
0.26) 10^-3. The data set, collected with the Belle detector at the KEKB e^+e^-
collider, consists of 31.9 million B\bar B events. We also present branching
fractions and momentum spectra for both chi_c1 and chi_c2 production.


title: New CLEO Results for |V_cb| and |V_ub|

abstract:
  We report recent measurements from CLEO of the first two moments of the
photon energy spectrum for b -> s gamma decays and the hadronic recoil mass in
B -> X_c l nu. These physical quantities allow one to fix non-perturbative
parameters occurring in calculations based on HQET and QCD. Predictions for
semileptonic decay rates within this same framework depend in addition on the
CKM matrix elements V_qq' governing quark mixing. We can thus extract |V_cb|
from the inclusive semileptonic decay rate of B mesons, and |V_ub| from the
lepton endpoint spectrum of B -> X_u l nu. Model dependence is reduced except
for the assumption of quark-hadron duality. Finally, we update the classic
measurement of |V_cb| from B -> D* l nu at zero recoil.


title:
Track Timing at $e^{+}e^{-}$ Linear Colliders with a Silicon Drift
  Detector Main Tracker

abstract:
  The track timing capabilities of a silicon drift detector based tracker for a
future linear electron-positron collider are evaluated. We show such a detector
can time tracks at the nanosecond, and for high-$P_{T}$, sub-nanosecond level.
This implies that, even for collider designs with the bunch spacing at 1.4 ns,
every track can be assigned to a particular bunch crossing at a confidence
level of up to two standard deviations. We suggest a choice for the drift axes
in the tracker layers to simultaneously optimize the momentum resolution and
track timing.


title: Measurement of the b-quark fragmentation function in Z0 decays

abstract:
  We present a measurement of the b-quark inclusive fragmentation function in
Z0 decays using a novel kinematic B-hadron energy reconstruction technique. The
measurement was performed using 350,000 hadronic Z0 events recorded in the SLD
experiment at SLAC between 1997 and 1998. We compared the sacled B-hadron
energy distribution with models of b-quark fragmentation and with several ad
hoc functional forms. A number of models and functions are excluded by the
data. The average scaled energy of weakly-decaying B hadrons was measured to be
<x_B>= 0.709 +-0.003 (stat) +-0.003 (syst) +-0.002 (model).


title:
Study of the $\rho$, $\omega$, $\phi\to\eta\gamma\to 7\gamma$ Decays
  with an SND Detector on a VEPP-2M Collider

abstract:
  The $e^+e^-\to\eta\gamma\to 7\gamma$ process was studied in the energy range
$2E=600\div 1060$ MeV with an SND detector on a VEPP-2M $e^+e^-$ collider. The
decay branching ratios $B(\phi\to\eta\gamma)=(1.343\pm 0.012\pm 0.055)\cdot
10^{-2}$, $B(\omega\to\eta\gamma)=(4.60\pm 0.72\pm 0.19)\cdot 10^{-4}$, and
$B(\rho\to\eta\gamma)=(2.69\pm 0.32\pm 0.16)\cdot 10^{-4}$ were measured.


title:
Measurement of the Ratio of Branching Fractions of the Upsilon(4S) to
  Charged and Neutral B Mesons

abstract:
  The ratio of charged and neutral B meson production at the Upsilon(4S),
f_{+-}/f_{00}, is measured through the decays B bar -> D* l- nu_l bar,
reconstructed using a partial reconstruction method where the D* is detected
only through a pion daughter from the decay D* -> D pi. Using data collected by
the CLEO II detector, the charged and neutral B decays are measured in such a
way that their ratio is independent of decay model, limited mainly by the
uncertainty in the relative efficiency for detecting neutral and charged pions.
This measurement yields the ratio of production fractions times the ratio of
semileptonic branching fractions, f_{+-}b_{+}/f_{00}b_0. Assuming that b_+/b_0
is equal to the lifetime ratio tau_+/tau_0 and using the world average value of
tau_+/tau_0 as input, we obtain f_{+-}/f_{00}=1.058+- 0.084+- 0.136.


title:
Measurement of the photon-proton total cross section at a center-of-mass
  energy of 209 GeV at HERA

abstract:
  The photon-proton total cross section has been measured in the process e+ p
-> e+ gamma p -> e+ X with the ZEUS detector at HERA. Events were collected
with photon virtuality Q^2 < 0.02 GeV^2 and average gamma-p center-of-mass
energy W_{gamma p} = 209 GeV in a dedicated run, designed to control systematic
effects, with an integrated luminosity of 49 nb^{-1}. The measured total cross
section is sigma_{tot}^{gamma p} = 174 +- 1 (stat.) +- 13 (syst.) microbarns.
The energy dependence of the cross section is compatible with parameterizations
of high-energy p-p and p-pbar data.


title: Measurement of the Hadronic Photon Structure Function F2gamma at LEP2

abstract:
  The hadronic structure of the photon F2gamma is measured as a function of
Bjorken x and of the photon virtuality Q2 using deep-inelastic scattering data
taken by the OPAL detector at LEP at e+e- centre-of-mass energies from 183 to
209 GeV. Previous OPAL measurements of the x dependence of F2gamma are extended
to an average Q2 of <Q2>=780GeV2 using data in the kinematic range 0.15 < x <
0.98. The Q2 evolution of F2gamma is studied for 12.1 < <Q2> < 780GeV2 using
three ranges of x. As predicted by QCD, the data show positive scaling
violations in F2gamma for the central x region 0.10-0.60. Several
parameterisations of F2gamma are in qualitative agreement with the measurements
whereas the quark-parton model prediction fails to describe the data.

Cascade and anti-cascade production in central Pb+Pb collisions at 158
  GeV/c per nucleon

abstract:
  Results of the production of Xi and Xi-bar hyperons in central Pb+Pb
interactions at 158 GeV/c per nucleon are presented. This analysis utilises a
global reconstruction procedure, which allows a measurement of 4pi integrated
yields to be made for the first time. Inverse slope paramters, which are
determined from an exponential fit to the transverse mass spectra, are shown.
Central rapidity densities are found to be 1.49 +- 0.08 and 0.33 +- 0.04 per
event per unit of rapidity for Xi and Xi-bar respectively. Yields integrated to
full phase space are 4.12 +- 0.02 and 0.77 +- 0.04 for Xi and Xi-bar. The ratio
of Xi-bar/Xi at mid-rapidity is 0.22 +- 0.03.


title: A study of nuclear effects in $\nu$ interactions with the NOMAD detector

abstract:
  Nuclear effects in \numucc interactions with carbon nuclei have been studied
by using backward going protons and $\pi^-$.
  Detailed analyses, of the momentum distributions and of the production rates,
have been carried out in order to understand the mechanism producing these
particles. The backward proton data have been compared with the predictions of
the reinteraction and the short range correlation models.


title: Studies of B decays to Charmonium at BABAR

abstract:
  Using 22.7 million BBbar events recorded with the BABAR detector, the
inclusive branching fractions for the production of J/psi, psi(2S) and Chi_c in
B decays are presented. Combining the charmonium state with a K+-, K0, K*+-,
K*0 or neutral pion, B decays are reconstructed exlusively and branching
fractions are determined. A preliminary study is also presented fot the B -->
eta_c K decay mode.

Outlook for development of a scintielectron detector with improved
  energy resolution

abstract:
  The development prospects have been considered of a scintillator-photodiode
type detector with improved energy resolution attaining several per cent
($R=1-2%$). The main contributions to the scintielectron detector energy
resolution have been analyzed theoretically and their theoretical and physical
limits determined. Experimental data have been presented on properties of
scintillators of promise confirming the possibilities to minimize each of the
resolution components. New ways are proposed to optimize the detector
statistical contribution and the scintillator intrinsic resolution. A special
role of the latter is outlined as the critical factor for the spectrometric
possibilities (threshold) of scintillation-photodiode type detector with
improved energy resolution at energy values $E_{\gamma}$ from $662 keV$ to $10
MeV$.

Search for T and CP Violation in B0-anti-B0 Mixing with Inclusive
  Dilepton Events

abstract:
  We report the results of a search for T and CP violation in B0-anti-B0 mixing
using an inclusive dilepton sample collected by the BaBar experiment at the
PEP-II B Factory. The asymmetry between (l+,l+) and (l-,l-) events allows us to
compare the probabilities P(anti-B0 -> B0) and P(B0 -> anti-B0) oscillations
and thus probe T and CP invariance. Using a sample of 23 million B-anti-B
pairs, we measure a same-sign dilepton asymmetry of A_(T/CP)=(0.5 +- 1.2(stat)
+- 1.4(syst))%. For the modulus of the ratio of complex mixing parameters p and
q, we obtain |q/p| = 0.998 +- 0.006(stat) +- 0.007(syst).

Pion Correlations and Resonance Effects in ppbar Annihilation to 4pi0 at
  Rest

abstract:
  We study pi0pi0 correlations in the exclusive reaction ppbar -> 4pi0 at rest
with complete reconstruction of the kinematics for each event. The inclusive
distribution shows a dip at small invariant mass of the pion pair while a small
enhancement in the double differential distribution is observed for small
invariant masses of both pion pairs. Dynamical models with resonances in the
final state are shown to be consistent with the data while the stochastic HBT
mechanism is not supported by the present findings.


title: Neutrinos from supernovae: experimental status and perspectives

abstract:
  I discuss the state of the art in the search for neutrinos from galactic
stellar collapses and the future perspectives of this field. The implications
for the neutrino physics of a high statistics supernova neutrino burst
detection by the network of detectors operating around the world are also
reviewed.


title:
Search for New Physics in Photon-Lepton Events in pbar-p Collisions at
  root-s= 1.8 TeV

abstract:
  We present the results of a search in pbar-p collisions at root-s=1.8 TeV for
anomalous production of events containing a photon and a lepton (e or mu), both
with large transverse energy, using 86 pb-1 of data collected with the Collider
Detector at Fermilab during the 1994-95 collider run at the Fermilab Tevatron.
The presence of large missing transverse energy, additional photons, or
additional leptons in these events is also analyzed. The results are consistent
with standard model expectations, with the possible exception of photon-lepton
events with large missing transverse energy, for which the observed total is 16
events and the expected mean total is 7.6 \pm 0.7 events.


abstract:
  The multilevel trigger system of the DIRAC experiment at CERN is presented.
It includes a fast first level trigger as well as various trigger processors to
select events with a pair of pions having a low relative momentum typical of
the physical process under study. One of these processors employs the drift
chamber data, another one is based on a neural network algorithm and the others
use various hit-map detector correlations. Two versions of the trigger system
used at different stages of the experiment are described. The complete system
reduces the event rate by a factor of 1000, with efficiency $\geq$95% of
detecting the events in the relative momentum range of interest.


title:
Frequency locking to a high-finesse Fabry-Perot cavity of a Frequency
  doubled Nd:YAG laser used as the optical phase modulator

abstract:
  We report on the frequency locking of a frequency doubled Nd:YAG laser to a
45 000 finesse, 87-cm-long, Fabry-Perot cavity using a modified form of the
Pound-Drever-Hall technique. Necessary signals, such as light phase modulation
and frequency correction feedback, are fed direcly to the infrared pump laser.
This is sufficient to achieve a stable locking of the 532 nm visible beam to
the cavity, also showing that the doubling process does not degrade laser
performances.


title: The D0 Detector at the Fermilab Tevatron in Run 2

abstract:
  The \d0 (DZERO) Detector at Fermilab is currently collecting data since March
1, 2001, called Run 2. The detector has undergone an extensive upgrade to
participate in the Run 2 data taking. The design of the detector meets the
requirements of the high luminosity environment provided by the accelerator.
This paper describes the upgraded detector subsystems and gives an outline of
the physics potentials associated with the upgrade.


title: Testing of Hamamatsu R5900-00-M64 Multi-Pixel PMTs for MINOS

abstract:
  The MINOS long baseline neutrino oscillation experiment is comprised of three
calorimeters, a Near Detector at FNAL, a Far Detector at the Soudan mine in
northern Minnesota, and a Calibration Detector in a test beam at CERN. The
light produced in the interactions of neutrinos in the Near Detector at FNAL
will be routed by optical fibres onto the pixels of Hamamatsu R5900-00-M64
multi-anode photomultiplier tubes. This article reports the measurements
performed on 15 of these tubes to evaluate them for their use in MINOS.


title: A Calculator for Confidence Intervals

abstract:
  A calculator program has been written to give confidence intervals on
branching ratios for rare decay modes (or similar quantities) calculated from
the number of events observed, the acceptance factor, the background estimate
and the associated errors. Results from different experiments (or different
channels from the same experiment) can be combined. The calculator is available
in http://www.slac.stanford.edu/~barlow/limits.html


title:
photon+jet process application for setting the absolute jet energy and
  determining the gluon distribution at the Tevatron Run II

abstract:
  We study the effect of application of new set of cuts, proposed in our
previous works, on the improvement of accuracy of the jet energy calibration
with p p->photon+Jet+X process at Tevatron. Monte Carlo events produced by the
PYTHIA 5.7 generator are used for this aim. The selection criteria for
photon+Jet event samples that would provide a good balance of photon and jet
transverse momenta and would allow to reduce the background are described. The
distributions of these events over photon transverse momenta and jet
pseudorapidity are presented. The features of photon+Jet events in the central
calorimeter region of the D0 detector (eta_jet < 0.7) are exposed. The
efficiency of the cuts used for background suppression is demonstrated.
  It is shown that the samples of photon+Jet events, gained with the cuts for
the jet energy calibration, may have enough statistics for determining the
gluon distribution inside a proton in the region of x < 10^{-3} and of Q^2 by
one order higher than that studied at HERA.


title:
On the Effect of Asymmetric Strange Seas and Isospin-Violating Parton
  Distribution Functions on sin2thetaW Measured at NuTeV

abstract:
  The NuTeV collaboration recently reported a value of sin2thetaW measured in
neutrino-nucleon scattering that is 3 standard deviations above the standard
model prediction. This result is derived assuming that (1) the strange sea is
quark-antiquark symmetric, s(x)=sbar(x), and (2) up and down quark
distributions are symmetric under the simultaneous interchange of u<->d and
p<->n. We report the impact of violations of these symmetries on sin2thetaW and
discuss the theoretical and experimental constraints on such asymmetries.


title: Long Baseline Neutrino Physics: From Fermilab to Kamioka

abstract:
  We have investigated the physics potential of very long baseline experiments
designed to measure nu_mu to nu_e oscillation probabilities. The principles of
our design are to tune the beam spectrum to the resonance energy for the matter
effect, and to have the spectrum cut off rapidly above this energy. The matter
effect amplifies the signal, and the cut-off suppresses backgrounds which
feed-down from higher energy. The signal-to-noise ratio is potentially better
than for any other conventional nu_mu beam experiment.
  We find that a beam from Fermilab aimed at the Super-K detector has excellent
sensitivity to sin^2(2theta_13) and the sign of Delta M^2. If the mass
hierarchy is inverted, the beam can be run in antineutrino mode with a similar
signal-to-noise ratio, and event rate 55% as high as for the neutrino mode.
  Combining the Fermilab beam with the JHF-Kamioka proposal adds very
complementary information. We find good sensitivity to maximal CP violation for
values of sin^2(2theta_13) ranging from 0.001 to 0.05.

The helicity amplitudes A$_{1/2}$ and A$_{3/2}$ for the D$_{13}(1520)$
  resonance obtained from the $\vec{\gamma} \vec{p} \to p \pi^0$ reaction}

abstract:
  The helicity dependence of the $\vec{\gamma} \vec{p} \to p \pi^0$ reaction
has been measured for the first time in the photon energy range from 550 to 790
MeV. The experiment, performed at the Mainz microtron MAMI, used a
4$\pi$-detector system, a circularly polarized, tagged photon beam, and a
longitudinally polarized frozen-spin target. These data are predominantly
sensitive to the $D_{13}(1520)$ resonance and are used to determine its
parameters.


title: Improved measurement of the CP-violating asymmetry amplitude sin2beta

abstract:
  We present updated results on time-dependent CP-violating asymmetries in
neutral B decays to several CP eigenstates. The measurements use a data sample
of about 62 million Upsilon(4S) --> B anti-B decays collected between 1999 and
2001 by the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC.
In this sample we study events in which one neutral B meson is fully
reconstructed in a final state containing a charmonium meson and the flavor of
the other neutral B meson is determined from its decay products. The amplitude
of the CP-violating asymmetry, which in the Standard Model is proportional to
sin2beta, is derived from the decay time distributions in such events. We
measure sin2beta = 0.75 +/- 0.09 (stat) +/- 0.04 (syst) and |\lambda| = 0.92
+/- 0.06 (stat) +/- 0.02 (syst). The latter is consistent with the Standard
Model expectation of no direct CP violation. These results are preliminary.


title:
Measurement of the Branching Fraction and CP Content for the Decay B0
  --> D*+ D*-

abstract:
  We report a measurement of the branching fraction of the decay B^0 --> D^{*+}
D^{*-} and of the CP-odd component of its final state using the BaBar detector.
With data corresponding to an integrated luminosity of 20.4 fb^{-1} collected
at the Upsilon(4S) resonance during 1999-2000, we have reconstructed 38
candidate signal events in the mode B^0 --> D^{*+}D^{*-} with an estimated
background of 6.2 \pm 0.5 events. From these events, we determine the branching
fraction to be BR(B^0 --> D^{*+}D^{*-}) = (8.3 +/- 1.6(stat) +/- 1.2(syst)) x
10^{-4}. The measured CP-odd fraction of the final state is 0.22 +/- 0.18(stat)
+/- 0.03(syst).


title: Modeling Deep Inelastic Cross Sections in the Few GeV Region

abstract:
  We present preliminary results on simple modifications and corrections to
GRV94 leading order parton distribution functions such that they can be used to
model electron,muon and neutrino deep-inelastic scattering cross sections at
low energies.


title:
A new class of binning free, multivariate goodness-of-fit tests: the
  energy tests

abstract:
  We present a new class of multivariate binning-free and nonparametric
goodness-of-fit tests. The test quantity \emph{energy} is a function of the
distances of observed and simulated observations in the variate space. The
simulation follows the probability distribution function $f_{0}$ of the null
hypothesis. The distances are weighted with a weighting function which can be
adjusted to the variations of $f_{0}$. We have investigated the power of the
test for a uniform and a Gaussian distribution of one or two variates,
respectively and compared it to that of conventional tests. The energy test
with a Gaussian weighting function is closely related to the Pearson $\chi
^{2}$ test but is more powerful in most applications and avoids arbitrary bin
boundaries. The test is especially powerful in the multivariate case.


title: Energy Flow and Rapidity Gaps Between Jets in Photoproduction at HERA

abstract:
  Dijet events in photon-proton collisions in which there is a large
pseudorapidity separation Delta eta > 2.5 between the two highest E_T jets are
studied with the H1 detector at HERA. The inclusive dijet cross sections are
measured as functions of the longitudinal momentum fractions of the proton and
photon which participate in the production of the jets, x_pjet and x_gjet
respectively, Delta eta, the pseudorapidity separation between the two highest
E_T jets, and E_T^gap, the total summed transverse energy between the jets.
Rapidity gap events are defined as events in which E_T^gap is less than
E_T^cut, for E_T^cut varied between 0.5 and 2.0 GeV. The fraction of dijet
events with a rapidity gap is measured differentially in Delta eta, x_pjet and
x_gjet. An excess of events with rapidity gaps at low values of E_T^cut is
observed above the expectation from standard photoproduction processes. This
excess can be explained by the exchange of a strongly interacting colour
singlet object between the jets.

First electron beam polarization measurements with a Compton polarimeter
  at Jefferson Laboratory

abstract:
  A Compton polarimeter has been installed in Hall A at Jefferson Laboratory.
This letter reports on the first electron beam polarization measurements
performed during the HAPPEX experiment at an electron energy of 3.3 GeV and an
average current of 40 $\mu$A. The heart of this device is a Fabry-Perot cavity
which increased the luminosity for Compton scattering in the interaction region
so much that a 1.4% statistical accuracy could be obtained within one hour,
with a 3.3% total error.


title:
The HLMA project: determination of high delta-m^2 LMA mixing parameters
  and constraint on |U_e3| with a new reactor neutrino experiment

abstract:
  In the forthcoming months, the KamLAND experiment will probe the parameter
space of the solar large mixing angle (LMA) MSW solution as the origin of the
solar neutrino deficit with $\nuebar$'s from distant nuclear reactors. If
however the solution realized in nature is such that $\Dm2_{sol} \gsim 2 \cdot
10^{-4}$ eV$^2$ (thereafter named the HLMA region), KamLAND will only observe a
rate suppression but no spectral distortion and hence it will not have the
optimal sensitivity to measure the mixing parameters. In this case, we propose
a new medium baseline reactor experiment located at Heilbronn (Germany) to pin
down the precise value of the solar mixing parameters. In this paper, we
present the Heilbronn detector site, we calculate the $\nuebar$ interaction
rate and the positron spectrum expected from the surrounding nuclear power
plants. We also discuss the sensitivity of such an experiment to |U_e3| in both
normal and inverted neutrino mass hierarchy scenarios. We then outline the
detector design, estimate background signals induced by natural radioactivity
as well as by in-situ cosmic ray muon interaction, and discuss a strategy to
detect the anti-neutrino signal 'free of background'.


title: Cosmogenesis Backgrounds, Experiment Depth and the Solar Neutrino TPC

abstract:
  A Time Projection Chamber (TPC) is one of the promising candidates to perform
unique measurements in solar neutrino physics. Its features will enable it to
work at depths of the order of 2000 mwe. This paper describes an estimation of
the expected cosmogenic background at different depths including also the
background due to fission activation of the TPC material above ground.


title: Precision Determination of V_ub at an e+ e- B Factory

abstract:
  Current methods of determining V_ub are dominated by theoretical
uncertainties. We present Monte Carlo simulations of three promising methods of
determining V_ub with small theoretical and experimental errors. We find that
with data samples of order 1,000 fb-1 the B factories will attain combined
experimental errors of a few % on V_ub, much smaller than the theoretical
errors associated with new inclusive methods. Lattice QCD offers the promise of
rate calculations of exclusive semileptonic decays with errors of a few %. A
data sample of order 10,000 fb-1, beyond the capabilities of the current B
factories, may be required to achieve an experimental error on the exclusive
rate comparable to the theoretical error.


title: Search for a Higgs Boson Decaying into Two Photons at LEP

abstract:
  A Higgs particle produced in association with a Z boson and decaying into two
photons is searched for in the data collected by the L3 experiment at LEP. All
possible decay modes of the Z boson are investigated. No signal is observed in
447.5 pb^-1 of data recorded at centre-of-mass energies up to 209 GeV. Limits
on the branching fraction of the Higgs boson decay into two photons as a
function of the Higgs mass are derived. A lower limit on the mass of a
fermiophobic Higgs boson is set at 105.4 GeV at 95% confidence level.


title:
Identification of single events in the HPGe detector: Comparison of
  various methods based on the analysis of simulated pulse shapes

abstract:
  Various methods of identification of single events in the HPGe detector are
compared on the basis of a program especially designed to simulate pulse shape
in a semi-conductor germanium detector. Capabilities of three following methods
are shown: (1) an application of the library of single pulse shapes, (2) the
single-parameter method, and (3) a separation on the basis of artificial neural
networks. The analysis was done in the context of an application of all
above-mentioned techniques in the energy interval around the expected neutrino
less double beta decay of Ge-76 in the Heidelberg-Moscow experiment.


title:
A Search for Muon-neutrino to Electron-neutrino and Muon-antineutrino to
  Electron-antineutrino Oscillations at NuTeV

abstract:
  Limits on $\nu_\mu \to \nu_e$ and $\bar\nu_\mu \to \bar\nu_e$ oscillations
are extracted using the NuTeV detector with sign-selected $\nu_\mu$ and
$\nub_\mu$ beams. In $\nub_\mu$ mode, for the case of $\sin^2 2\alpha = 1$,
$\Delta m^2 > 2.6$ ${\rm eV^2}$ is excluded, and for $\Delta m^2 \gg 1000$
${\rm eV^2}$, $\sin^2 2\alpha > 1.1 \times 10^{-3}$. The NuTeV data exclude the
high $\Delta m^2$ end of $\bar\nu_\mu \to \bar\nu_e$ oscillations parameters
favored by the LSND experiment without the need to assume that the oscillation
parameters for $\nu$ and $\nub$ are the same. We present the most stringent
experimental limits for $\nu_\mu (\bar{\nu}_\mu) \to \nu_e (\bar{\nu}_e)$
oscillations in the large $\Delta m^2$ region.


title:
Impact of Energy and Luminosity upgrades at LHC on the Physics program
  of ATLAS

abstract:
  The impact on the physics capabilities of the ATLAS detector of possible LHC
upgrades is discussed. As a benchmark, an increase in the luminosity by a
factor of ten is considered. For comparison, a doubling of the LHC energy is
also explored. Both upgrades significantly enhance the physics capabilities of
ATLAS. As measured in terms of the mass reach for new particles, the energy
upgrade is more powerful. However, in cases where the effect of an upgrade is
to increase the precision of measurements as a result of the larger data
samples, the luminosity upgrade can be at least as powerful. The pile-up of
minimum bias events at higher luminosity could limit the physics performance of
ATLAS in areas where tagging of forward jets is needed.


title:
Search for charginos nearly mass degenerate with the lightest neutralino
  in e+e- collisions at centre-of-mass energies up to 209GeV

abstract:
  A search for charginos nearly mass degenerate with the lightest neutralino is
performed with the data collected by the ALEPH detector at LEP, at
centre-of-mass energies between 189 and 209 GeV, corresponding to an integrated
luminosity of 628 pb-1. The analysis is based on the detection of isolated and
energetic initial state radiation photons, produced in association with
chargino pairs whose decay products have little visible energy. The number of
candidate events observed is in agreement with that expected from Standard
Model background sources. These results are combined with those of other direct
searches for charginos, and a lower limit of 88 GeV/c2 at 95 % confidence level
is derived for the chargino mass in the case of heavy sfermions, irrespective
of the chargino-neutralino mass difference.


title:
Upper limits for neutrino oscillations muon-antineutrino to
  electron-antineutrino from muon decay at rest

abstract:
  The KARMEN experiment at the spallation neutron source ISIS used \numub from
\mup--decay at rest in the search for neutrino oscillations \numubnueb in the
appearance mode, with p(\nueb,e+)n as detection reaction of \nueb. In total, 15
candidates fulfill all conditions for the \nueb signature, in agreement with
the background expectation of 15.8+-0.5 events, yielding no indication for
oscillations. A single event based likelihood analysis leads to upper limits on
the oscillation parameters: sin^2(2theta)<1.7x10e-3 for Dm^2>100 eV^2 and
Dm^2<0.055 eV^2 for sin^2(2theta)=1 at 90% confidence. Thus, KARMEN does not
confirm the LSND experiment and restricts significantly its favored parameter
region for \numubnueb.


title:
A measurement of the t dependence of the helicity structure of
  diffractive rho meson electroproduction at HERA

abstract:
  The helicity structure of the diffractive electroproduction of rho mesons, e
+ p -> e + rho + Y, is studied in a previously unexplored region of large
four-momentum transfer squared at the proton vertex, t: 0 < t' < 3 GeV^2, where
t' = |t| - |t|_min. The data used are collected with the H1 detector at HERA in
the kinematic domain 2.5 < Q^2 < 60 GeV^2, 40 < W < 120 GeV. No t dependence of
the r^04_00 spin density matrix element is found. A significant t dependent
helicity non-conservation from the virtual photon to the rho meson is observed
for the spin density matrix element combinations r^5_00+2r^5_11 and
r^1_00+2r^1_11. These t dependences are consistently described by a
perturbative QCD model based on the exchange of two gluons.


title:
Statistical Analysis of Different
  Muon-antineutrino->Electron-antineutrino Searches

abstract:
  A combined statistical analysis of the experimental results of the LSND and
KARMEN \numubnueb oscillation search is presented. LSND has evidence for
neutrino oscillations that is not confirmed by the KARMEN experiment. This
joint analysis is based on the final likelihood results for both data sets. A
frequentist approach is applied to deduce confidence regions. At a combined
confidence level of 36%, there is no area of oscillation parameters compatible
with both experiments. For the complementary confidence of 1-0.36=64%, there
are two well defined regions of oscillation parameters (sin^2(2th),Dm^2)
compatible with both experiments.


title:
Search for gauge mediated SUSY breaking topologies in e+e- collisions at
  centre-of-mass energies up to 209GeV

abstract:
  A total of 628$\invpb$ of data collected with the ALEPH detector at
centre-of-mass energies from 189 to 209 GeV is analysed in the search for gauge
mediated SUSY breaking (GMSB) topologies. These topologies include two
acoplanar photons, non-pointing single photons, acoplanar leptons, large impact
parameter leptons, detached slepton decay vertices, heavy stable charged
sleptons and multi-leptons plus missing energy final states. No evidence is
found for new phenomena, and lower limits on masses of supersymmetric particles
are derived. A scan of a minimal GMSB parameter space is performed and lower
limits are set for the next-to-lightest supersymmetric particle (NLSP) mass at
54$\gevcc$ and for the mass scale parameter $\Lambda$ at 10$\tevcc$,
independently of the NLSP lifetime. Including the results from the neutral
Higgs boson searches, a NLSP mass limit of 77$\gevcc$ is obtained and values of
$\Lambda$ up to 16$\tevcc$ are excluded.

Summary of Discussion Question 4: Energy Expandability of a Linear
  Collider

abstract:
  We report on Discussion Question 4, in Sub-group 1 (`TeV-class') of the
Snowmass Working Group E3: `Experimental Approaches: Linear Colliders', which
addresses the energy expandability of a linear collider. We first synthesize
discussions of the energy reach of the hardware of the 500 GeV designs for
TESLA and NLC/JLC. Next, we review plans for increasing the energy to 800-1000
GeV. We then look at options for expanding the energies to 1500 GeV and sketch
the two-beam accelerator approach to achieving multi-TeV energies.


title:
Measurement of the Mass of the W Boson in e+e- collisions using the
  Fully Leptonic Channel

abstract:
  A novel method of determining the mass of the W boson in the W+W- -> lnu lnu
channel is presented and applied to 667pb^-1 of data recorded at the center-of-
mass energies in the range 183-207 GeV with the OPAL detector at LEP. The
Measured energies of charged leptons and the results of a new procedure based
on an approximate kinematic reconstruction of the events are combined to give:
Mw=80.41+-0.41+-0.13 GeV, when the first error is statistical and the second is
systematic. The systematic error is dominated by the uncertainty on the lepton
energy, which is calibrated using data, and the parameterization of the
variables used in the fitting, which is obtained using Monte Carlo events. Both
of these are limited by statistics.


title: Search for Charmless Two-body Baryonic Decays of B Mesons

abstract:
  We report the results of a search for the rare baryonic decays $B^0 \to
p\bar{p}$, $\Lambda\bar{\Lambda}$, and $B^+ \to p\bar{\Lambda}$. The analysis
is based on a data set of $31.7\times 10^6 B\bar{B}$ events collected by the
Belle detector at the KEKB $e^+e^-$ collider. No statistically significant
signals are found, and we set branching fraction upper limits ${\mathcal B}(B^0
\to p\bar{p}) < 1.2 \times 10^{-6}$, ${\mathcal B}(B^0 \to
\Lambda\bar{\Lambda}) < 1.0 \times 10^{-6}$, and ${\mathcal B}(B^+ \to
p\bar{\Lambda}) < 2.2 \times 10^{-6}$ at the 90% confidence level.

  This Paper summarize the present status and near term perspectives for
Diffractive Physics at Tevatron. We describe the new detectors that are being
installed around the CDF and D0 interaction regions, and discuss he physics
topics accessible in view of these upgrades.


title: A Very Forward Proton Spectrometer for H1

abstract:
  A new, very forward, proton spectrometer with large acceptance will be
installed in the proton beam line of the H1 experiment in 2003. The
spectrometer, located 220 m downstream of the interaction point, is based on
the Roman Pot technique and consists of two stations in the cold section of the
proton beam line. A brief description of this new device and expected physics
results are presented.


title: Measurement of the D+ --> K*0bar l+ nu_l Branching Fraction

abstract:
  Using 13.53/fb of CLEO data, we have measured the ratios of the branching
fractions R+(e) = BF(D+ --> K*0bar e+ nu_e) / BF(D+ --> K- pi+ pi+), R+(mu) =
BF(D+ --> K*0bar mu+ nu_mu) / BF(D+ --> K- pi+ pi+) and the combined branching
fraction ratio R+(l) = BF(D+ --> K*0bar l+ nu_l) / BF(D+ --> K- pi+ pi+). We
find R+(e) = 0.74 +- 0.04 +- 0.05, R+(mu) = 0.72 +- 0.10 +- 0.06 and R+(l) =
0.74 +- 0.04 +- 0.05, where the first and second errors are statistical and
systematic respectively. The known branching fraction BF(D+ --> K- pi+ pi+)
leads to: BF(D+ --> K*0bar e+ nu_e) = (6.7 +- 0.4 +- 0.5 +- 0.4)%, BF(D+ -->
K*0bar mu+ \nu_mu) = (6.5 +- 0.9 +- 0.5 +- 0.4)% and BF(D+ --> K*0bar l+ nu_l)
= (6.7 +- 0.4 +- 0.5 +- 0.4)%, where the third error is due to the uncertainty
in BF(D+ --> K- pi+ pi+).


title: Evidence for new interference phenomena in the decay D+ to K- pi+ mu+ nu

abstract:
  Using a large sample of charm semileptonic decays collected by the FOCUS
photoproduction experiment at Fermilab, we present evidence for a small, even
spin K- \pi+ amplitude that interferes with the dominant K*0 component in the
K-pi+ mu- nu final state. Although this interference significantly distorts the
decay angular distributions, the new amplitude creates only a very small
distortion to the observed kaon pion mass distribution when integrated over the
other kinematic variables describing the decay. Our data can be described by
K*0 interference with either a constant amplitude or broad spin zero resonance.


title: Improved Measurement of |Vcb| using B --> D* l nu Decays

abstract:
  We determine the weak coupling |Vcb| between the b and c quarks using a
sample of 3 million BB-bar events in the CLEO detector at the Cornell Electron
Storage Ring. We determine the yield of reconstructed B --> D* l nu decays as a
function of w, the boost of the D* in the B rest frame, and from this we obtain
the differential decay rate dGamma/dw. By extrapolating dGamma/dw to w=1, the
kinematic end-point at which the D* is at rest relative to the B, we extract
the product |Vcb|F(1), where F(1) is the form factor at w=1. We find |Vcb|F(1)
= 0.0431 +- 0.0013 (stat.) +- 0.0018 (syst.).


title: CLEO-c and CESR-c: A New Frontier in Weak and Strong Interactions

abstract:
  We report on the physics potential of a proposed conversion of the CESR
machine and the CLEO detector to a charm and QCD factory: CLEO-c and CESR-c
that will make crucial contributions to flavor physics in this decade and
offers our best hope for mastering non-perturbative QCD which is essential if
we are to understand strongly coupled sectors in the new physics that lies
beyond the Standard Model.


title: A Measurement of the B0 --> J/psi pi+pi- Branching Fraction

abstract:
  We present a preliminary measurement of the branching fraction for the decay
of the neutral $B$ meson into the final state J/$\psi\pi^+\pi^-$. The data set
contains approximately 56 million $B\bar{B}$ pairs produced at the
$\Upsilon(4S)$ resonance and recorded by the BaBar detector at the PEP-II
$e^+e^-$ collider. The result of this analysis is $\mathcal{B}(B^0\to
J/\psi\pi^+\pi^-$) = (5.0 $\pm$ 0.7 $\pm$ 0.6)$\times 10^{-5}$, where the first
error is statistical and the second is systematic.


title: Rare B Decays to States Containing a J/psi Meson

abstract:
  We report preliminary measurements of the branching fractions for B+ -> J/psi
phi K+, B0 -> J/psi phi K0S, B0 -> J/psi phi, B0 -> J/psi eta and B -> J/psi
eta' using 56 million BBbar events collected at the Y(4S) resonance with the
BABAR detector at PEP-II. We measure branching fractions of B(B+ -> J/psi phi
K+)=(4.4+-1.4(stat)+-0.7(syst))*10^-5 and B(B0 -> J/psi phi
K0S)=(5.1+-1.9(stat)+-0.9(syst))*10^-5, and set upper limits at 90% C.L. for
branching fractions, B(B -> J/\psi phi)< 0.95*10^-5, B(B -> J/\psi eta)<
2.7*10^-5, and B(B -> J/\psi eta')< 6.4*10^-5.


title:
Measurement of the B0 Lifetime with Partial Reconstruction of B0bar ->
  D*+ rho-

abstract:
  A sample of about 5500 $\bar B^0 \to D^{*+} \rho^-$ and 700 $\bar B^0 \to
D^{*+} a_1^-$ events is identified, using the technique of partial
reconstruction, among 22.7 $B\bar B$ pairs collected by the BaBar experiment at
the PEP-II storage ring. With these events, the $B^0$ lifetime is measured to
be $1.616 \pm 0.064 \pm 0.075$ ps. This measurement serves as validation for
the procedures required to measure $\sin(2\beta + \gamma)$ with partial
reconstruction of $\bar B^0 \to D^{*+} \rho^-$.


title: New measurements of the D0 and D+ lifetimes

abstract:
  A high statistics sample of photoproduced charm particles from the
FOCUS(E831) experiment at Fermilab has been used to measure the D0 and D+
lifetimes. Using about 210000 D0 and 110000 D+ events we obtained the following
values: 409.6 +/- 1.1 (statistical) +/- 1.5 (systematic) fs for D0 and 1039.4
+/- 4.3 (statistical) +/- 7.0 (systematic) fs for D+.


title:
A Measurement of the Neutral B Meson Lifetime using Partially
  Reconstructed B0 --> D*-pi+ Decays

abstract:
  The neutral B meson lifetime has been measured with the data collected by the
BABAR detector at the PEP-II storage ring during the year 2000 for a total
integrated luminosity of 20.3 fb-1. The B0 --> D*- pi+ decays have been
selected with a partial reconstruction method in which only the fast pion from
the B0 decay and the slow pion from D*- --> D0 bar pi- are reconstructed. The
B0 lifetime has been measured to be 1.510 +/- 0.040 +/- 0.038 ps with a sample
of 6971 +/- 241 reconstructed signal events.


title:
Measurement of the Q2 and energy dependence of diffractive interactions
  at HERA

abstract:
  Diffractive dissociation of virtual photons, gamma* p-->Xp, has been studied
in ep interactions with the ZEUS detector at HERA using an integrated
luminosity of approx. 10 pb^-1. The data cover photon virtualities 0.17 < Q^2<
0.70 GeV^2 and 3 < Q^2< 80 GeV^2 with 3<M_X<38 GeV, where M_X is the mass of
the hadronic final state.


title:
Branching Fraction Measurements of the Decays B -> EtaC K, where EtaC ->
  KKbarPi and EtaC -> 4K

abstract:
  In this report, we present the observation of the exclusive decays B0 -> EtaC
K0 and B+ -> EtaC K+, and the measurement of the related branching fractions.
Using a sample of 22.7x10^6 Upsilon(4S) -> BBbar decays collected with the
BABAR detector at the SLAC PEP-II asymmetric B Factory during 1999-2000, we
have observed statistically significant signals in the EtaC -> KsK+Pi- and
K+K-Pi0 channels and set upper limits in the EtaC -> K+K-K+K- channels. All the
results presented are preliminary.
  We have measured BF(B+ -> EtaC K+) = (1.50 +/- 0.19 +/- 0.15 +/-
0.46)x10^{-3}
  BF(B0 -> Etac K0) = (1.06 +/- 0.28 +/- 0.11 +/- 0.33)x10^{-3} where the first
error is statistical, the second systematic and the last due to the uncertainty
on the world average EtaC -> KKbarPi branching fraction.


title: Search for RP-violating SUSY and excited fermions at HERA

abstract:
  Recent results from searches for physics beyond the Standard Model (SM) in
$e^\pm$-proton collisions at a center of mass energy of 300 -- 318 GeV at HERA
are presented. Searches for excitations of fermions and for the production of
squarks in R-parity-violating Supersymmetry (SUSY) are reviewed.


title: Inclusive Semileptonic B Decays at BABAR

abstract:
  We present measurements of the inclusive semileptonic branching fractions of
charged and neutral B mesons using 20.6 fb-1 of data measured at the
Upsilon(4S) with the BABAR detector. Events are tagged with a fully
reconstructed hadronic decay of a B meson. The correlation between the flavor
of the tag B meson and the electron charge allows the separation of prompt
semileptonic B decays and cascade semileptonic charm decays. We obtain the
preliminary inclusive semileptonic branching fraction of charged B mesons b+ =
0.103+/-0.006+/-0.005, neutral B mesons b0 = 0.104+/-0.008+/-0.005, their
average b = 0.104+/-0.005+/-0.004, and their ratio b+/b0 = 0.99+/-0.10+/-0.03.


title: Study of CP-Violating Asymmetries in B0 -> pi+pi- Decays

abstract:
  We present a measurement of CP-violating asymmetries in B0 -> pi+pi- decays
based on a 41.8 fb-1 data sample collected at the Upsilon(4S) resonance with
the Belle detector at the KEKB asymmetric-energy e+e- collider. We fully
reconstruct one neutral B meson as a B0 -> pi+pi- CP eigenstate and identify
the flavor of the accompanying B meson from its decay products. From the
asymmetry in the distribution of the time intervals between the two B meson
decay points, we obtain the CP-violating asymmetry parameters Spipi = -1.21
+0.38/-0.27(stat) +0.16/-0.13(syst) and Apipi = +0.94 +0.25/-0.31(stat) +/-
0.09(syst).


title: Large bulk matter search for fractional charge particles

abstract:
  We have carried out the largest search for stable particles with fractional
electric charge, based on an oil drop method that incorporates a horizontal
electric field and upward air flow. No evidence for such particles was found,
giving a 95% C.L. upper limit of $1.17\times 10^{-22}$ particles per nucleon on
the abundance of fractional charge particles in silicone oil for $0.18 e \le
|Q_{residual}| \le 0.82 e$. Since this is the first use of this new method we
describe the advantages and limitations of the method.


title: European accelerator-based neutrino projects

abstract:
  Future neutrino projects in Europe will follow two distinct time lines. On
the medium term, they will be dominated by the CERN-Gran Sasso long-baseline
project, with two experiments OPERA and ICARUS, mainly concentrated on $\tau$
appearance. On the longer term, several projects are under discussion. A new
proton driver at CERN that accelerates a 4 MW beam to 2.2 GeV of energy would
open the possibility of a low-energy super-beam, possibly sent to the French
laboratory under the Frejus. A new radioactive heavy ion facility could produce
a pure $\nu_e$ beam, to be used independently or simultaneously with the
super-beam. In the framework of R&D for Super-Beam and Neutrino Factory, the
HARP experiment is studying hadron production at low energies on various
targets.
