Optimizing the Linear Collider Detector for the Measurement of the Higgs
  to Charm Branching Ratio

abstract:
  Several different vertex detector designs for the Linear Collider
Detector(LCD) are evaluated in the context of measurements of the branching
ratio of the standard model Higgs particle decaying into charm/anti-charm final
states. Fast Monte Carlo simulations are used to model the detector and neural
network-optimized flavor tagging is used to perform the measurements. These
tools are used to study the effects of pixel resolution, material thickness,
and inner layer radius on the flavor tagging efficiency-purity curve and
ultimately on the branching ratio measurement error.


title: Visions of ep physics

abstract:
  The subject of lepton-hadron scattering is discussed from its earliest
beginnings, concentrating on what we have learnt from the HERA electron-proton
storage ring. A brief selection of the HERA I results most relevant to LHC are
discussed. The HERA and ZEUS upgrades are outlined, together with the HERA II
physics programme. The impact of HERA results on LHC is discussed, in
particular in the areas of luminosity measurement, background estimates and
possible signatures of new physics. Finally, possible future developments in
lepton-proton physics beyond HERA II are discussed.


title: SIMDET - Version 4 A Parametric Monte Carlo for a TESLA Detector

abstract:
  A new release of the parametric detector Monte Carlo program \verb+SIMDET+
(version 4.01) is now available. We describe the principles of operation and
the usage of this program to simulate the response of a detector for the TESLA
linear collider. The detector components are implemented according to the TESLA
Technical Design Report. All detector component responses are treated in a
realistic way using a parametrisation of results from the {\em ab initio} Monte
Carlo program \verb+BRAHMS+. Pattern recognition is emulated using a complete
cross reference between generated particles and detector response. Also, for
charged particles, the covariance matrix and $dE/dx$ information are made
available. An idealised energy flow algorithm defines the output of the
program, consisting of particles generically classified as electrons, photons,
muons, charged and neutral hadrons as well as unresolved clusters. The program
parameters adjustable by the user are described in detail. User hooks inside
the program and the output data structure are documented.

Measurement of Gamma(phi -> eta' gamma)/Gamma(phi -> eta gamma) and the
  pseudoscalar mixing angle

abstract:
  We have measured the radiative decays phi -> eta gamma, phi ->etaprime gamma
selecting pi+ pi- gamma gamma gamma final state in a sample of about 5 times
10^7 phi mesons produced at the Frascati phi factory DAFNE. We obtain Gamma(phi
-> etaprime gamma)/Gamma(phi -> eta gamma)=(4.70 +- 0.47 +- 0.31) times 10^-3.
  From this result we derive new accurate values for the branching ratio BR(phi
->etaprime gamma) = (6.10 +- 0.61 +- 0.43) times 10^-5, and the mixing angle of
pseudoscalar mesons in the flavour basis phi_P=(41.8 +1.9 -1.6) degrees.


title: Lectures on HERA physics

abstract:
  In these lectures I introduce the basics of HERA physics and give a survey of
the major aspects, discussing in somewhat more depth the subject of low $x$
physics.


title: A mass formula for baryon resonances

abstract:
  Light-baryon resonances with u,d, and s quarks only can be classified using
the non-relativistic quark model. When we assign to baryon resonances with
total angular momenta J intrinsic orbital angular momenta L and spin S we make
the following observations: plotting the squared masses of the light-baryon
resonances against these intrinsic orbital angular momenta L, Delta's with even
and odd parity can be described by the same Regge trajectory. For a given L,
nucleon resonances with spin S=3/2 are approximately degenerate in mass with
Delta resonances of same total orbital momentum L. To which total angular
momentum L and S couple has no significant impact on the baryon mass. Nucleons
with spin 1/2 are shifted in mass; the shift is - in units of squared masses -
proportional to the component in the wave function which is antisymmetric in
spin and flavor. Sequential resonances in the same partial wave are separated
in mass square by the same spacing as observed in orbital angular momentum
excitations. Based on these observations, a new baryon mass formula is proposed
which reproduces nearly all known baryon masses.


title:
Measurements of Relative Branching Ratios of $\Lambda_{c}^{+}$ Decays
  into States Containing $\Sigma$

abstract:
  We have studied the Cabibbo suppressed decay (\Lambda_{c}^{+}\to \Sigma
^{+}K^{*0}(892)) and the Cabibbo favored decays (\Lambda_{c}^{+}\to \Sigma
^{+}K^{+}K^{-}), (\Lambda_{c}^{+}\to \Sigma ^{+}\phi) and (\Lambda_{c}^{+}\to
\Xi ^{*0}(\Sigma^{+}K^{-})K^{+}) and measured their branching ratios relative
to (\Lambda_{c}^{+}\to \Sigma ^{+}\pi ^{+}\pi ^{-}) to be ((7.8\pm 1.8\pm
1.3)%), ((7.1\pm 1.1\pm 1.1)%), ((8.7\pm 1.6\pm 0.6)%) and ((2.2\pm 0.6\pm
0.6)%), respectively. The first error is statistical and the second is
systematic. We also report two 90% confidence level limits (\Gamma
(\Lambda_{c}^{+}\to \Sigma ^{-}K^{+}\pi ^{+})/\Gamma (\Lambda_{c}^{+}\to
\Sigma^{+}K^{*0}(892))<35%) and (\Gamma (\Lambda_{c}^{+}\to \Sigma
^{+}K^{+}K^{-})_{NR}/\Gamma(\Lambda_{c}^{+}\to \Sigma ^{+}\pi ^{+}\pi
^{-})<2.8%).


title: Observation of the decay B^0->D+D*-

abstract:
  We report the first observation of the decay B^0->D+-D*-+ with the Belle
detector at the KEKB e^+e^- collider operated at the Upsilon(4S) resonance. The
sum of branching fractions B(B^0->D+D*-)+B(B^0->D-D*+) is measured to be
(1.17+-0.26+0.22-0.25)x10^-3 using the full reconstruction method where both
charmed mesons from B^0 decays are reconstructed. A consistent value
((1.48+-0.38+0.28-0.31)x10^-3) is obtained using a partial reconstruction
technique that only uses the slow pion from the D*- ->bar D^0pi- decay and a
fully reconstructed D+ to reconstruct the B^0.


title: The CLEO-c Physics Program

abstract:
  The CLEO collaboration at the Cornell Electron Storage Ring (CESR) is
proposing a three-year experiment that specifically emphasizes charm and QCD
studies in the energy range $\sqrt{s}=3$--$5 $GeV, utilizes the existing
detector and requires minimal modification of CESR to produce a luminosity
${\cal{L}}=(1-5)\times10^{32} {\rm cm^{-2}sec^{-1}}$. Key features of this
``CLEO-c'' physics program are summarized.

  Using data from both solar and atmospheric neutrinos, Super-Kamiokande has
provided fundamental information on neutrino flavor mixing and neutrino mass
square differences.


title:
X-Ray Multi-Energy Introscopy Systems with New Semiconductor
  Scintillators

abstract:
  Theoretical background and data on the ways of practical realization are
presented, related to the problem of detection of dangerous organic objects
(explosives, drugs, etc.) in the presence of other organic substances with
atomic number differing by no more than 20-30%. For this purpose, multi-energy
X-ray introscopy is used. It has been shown that the "weakest link" in the
existing multi-energy introscopes used for safety inspection and medicine are
detectors of ionizing radiation. In particular, critical is the type of
scintillator used in the low-energy detection subsystem. Data are presented on
design principles and properties of combined detectors based on a new type of
semiconductor scintillators (SCS) -- $ZnSe(Te,O)$, with conversion efficiency
of 19-22%, afterglow level less then $0.05 %$ after $10 ms$, and radiation
stability up to $500 Mrad$. Results are given on the practical use of
experimental samples of the low-energy detector subsystem based on the new SCS
material in two-energy introscopes of the 4th and 5th generation.


title:
Multi-energy radiography on the basis of "scintillator-photodiode"
  detectors

abstract:
  For reconstruction of the spatial structure and thicknesses of complex
objects and materials, it is proposed to use multi-radiography with detection
of X-ray or gamma-radiation by combined detector arrays of
scintillator-photodiode type. Experimental studies have been carried out of the
energy dependence of sensitivity of dual-energy inspection systems based on
scintillators $ZnSe(Te)$ and $CsI(Tl)$.


title:
Measurement of the Ratio of b Quark Production Cross Sections in
  Antiproton-Proton Collisions at 630 GeV and 1800 GeV

abstract:
  We report a measurement of the ratio of the bottom quark production cross
section in antiproton-proton collisions at 630 GeV to 1800 GeV using bottom
quarks with transverse momenta greater than 10.75 GeV identified through their
semileptonic decays and long lifetimes. The measured ratio
sigma(630)/sigma(1800) = 0.171 +/- .024 +/- .012 is in good agreement with
next-to-leading order (NLO) quantum chromodynamics (QCD).


title:
Measurement of diffractive production of D*+-(2010) mesons in deep
  inelastic scattering at HERA

abstract:
  Diffractive production of D*+-(2010) mesons in deep inelastic scattering has
been measured with the ZEUS detector at HERA using an integrated luminosity of
44.3 pb-1. Diffractive charm production is identified by the presence of a
large rapidity gap in the final state of events in which a D*+-(2010) meson is
reconstructed in the decay channel D*+ -> (D0 -> K-pi+) pi+ (+ charge
conjugate). Differential cross sections when compared with theoretical
predictions indicate the importance of gluons in such diffractive interactions.


title: Measurement of the Charm structure Function F2c of the Photon at LEP

abstract:
  The production of charm quarks is studied in deep-inelastic electron-photon
scattering using data recorded by the OPAL detector at LEP at normal e+e-
centre-of-mass energies from 183 to 209 GeV. The charm quarks have been
identified by full reconstruction of charged D* mesons using their decays into
D0pi with the D0 observed in two decay modes with charged particle final
states, Kpi and K3pi. The cross-section sigma(D*) for production of charged D*
in the reaction e+e- -> e+e-D*X is measured in a restricted kinematical region
using two bins in Bjorken x, 0.0014 < x < 0.1 and 0.1 < x < 0.87. From
sigma(D*) the charm production cross-section sigma(e+e- -> e+e- ccbar X) and
the charm structure function of the photon F 2,c are determined in the region
0.0014 < x < 0.87 and 5 < Q2 < 100 GeV2. For x > 0.1 the perturbative QCD
calculation at next-to-leading order agrees perfectly with the measured
cross-section. For x < 0.1 the measured cross-section is 43.8 +- 14.3 +- 6.3 +-
2.8 pb with a next-to-leading order prediction of 17.0+2.9-2.3 p.b


title:
Decay-mode independent searches for new scalar bosons with the OPAL
  detector at LEP

abstract:
  This paper describes topological searches for neutral scalar bosons S0
produced in association with a Z0 boson via the Bjorken process e+e- -> S0Z0 at
centre-of-mass energies of 91 GeV and 183-209 GeV. These searches are based on
studies of the recoil mass spectrum of Z0 -> e+e- and mu+mu- events on a search
for S0Z0 with Z0 -> nunu bar and S0 -> e+e- or photons. They cover the decays
of the S0 into an arbitrary combination of hadrons, leptons, photons and
invisible particles as well as the possibility that it might be stable. No
indication for a signal is found in the data and upper limits on the cross
section of the Bjorken process are calculated. Cross-section limits are given
in terms of a scale factor k with respect to the Standrad Model cross section
for the Higgs-strahlung process e+e- -> H0smZ0. These results can be
interpreted in general scenarios independently of the decay modes of the S0.
The examples considered here are the production of a single new scalar particle
with a decay width smaller than the detector mass resolution, and for the first
time, two scenarios with continuous mass distributions, due to a single very
broad state or several states close in mass.


title: Review of Experimental Searches for Bs Oscillations

abstract:
  The current status of experimental searches for Bs oscillations is reviewed.
The three ALEPH analyses have been improved since Summer 2001, and submitted
for publication. The combination of all available analyses is presented and
discussed.


title: Observation of B to K_S^0 pi+ pi- and Evidence for B to K*pm pi mp

abstract:
  We report on a search for charmless hadronic B decays to the three-body final
states, K0S h+ pi-, K+ h- pi0, K0S h+ pi0 (h+- denotes a charged pion or kaon),
and their charge conjugates, using 13.5 fb^{-1} of integrated luminosity
produced with center-of-mass energies near 10.6 GeV, and collected with the
CLEO detector. We observe the decay B --> K0 pi+ pi- with a branching fraction
(50 +10-9(stat.) +-7(syst.)) x 10^{-6} and the decay B --> K*+(892) pi- with a
branching fraction (16 +6-5(stat.) +-2(syst.)) x 10^{-6}.


title: Physics Potential at FNAL with Stronger Proton Sources

abstract:
  This document is the second in a series of reports on the exciting physics
that would be accessible at Fermilab in the event of an upgraded proton source.
Where the first report covered a broad range of topics, this report focuses
specifically on three areas of study: there are brief discussions on the new
measurements one could make in both the neutron and anti-proton sectors, and
then a detailed discussion of what could be achieved in the neutrino
oscillation sector using an upgraded proton source to supply the NuMI beamline
with more protons. If one places a new detector optimized for $\nu_e$
appearance at a new location slightly off the axis defined by the MINOS
experiment, that new experiment would be ideal for making the next important
steps in lepton flavor studies, namely, the search for $\nu_\mu \to \nu_e$ at
the atmospheric mass splitting, and CP violations. The report concludes with a
summary of proton economics and demands for increased proton intensity for the
Booster and Main Injector: what the proton source at Fermilab can currently
supply, and what adiabatic changes could be implemented to boost the proton
supply on the way from here to a proton driver upgrade.


title:
A study of the reaction pim p --> omega pim p at 18 GeV/c: The D and S
  decay amplitudes for b1(1235) --> omega pi

abstract:
  The reaction pim p --> omega pim p, omega --> pip pim pi0 has been studied at
18 GeV/c. The omega pim mass spectrum is found to be dominated by the b1(1235).
Partial Wave Analysis shows that b1 production is dominated by natural parity
exchange. The S-wave and D-wave amplitudes for b1(1235) --> omega pi have been
determined, and it is found that the amplitude ratio, |D/S| = 0.269 +/-
(0.009)stat +/- (0.01)sys and the phase difference, phi(D-S) = 10.54 deg +/-
(2.4)stat +/- (3.9)sys.


title: Status Report of the MACRO Experiment for the year 2001

abstract:
  In this 2001 status report of the MACRO experiment, results are presented on
atmospheric neutrinos and neutrino oscillations, high energy neutrino
astronomy, searches for WIMPs, search for low energy stellar gravitational
collapse neutrinos, stringent upper limits on GUT magnetic monopoles,
nuclearites and lightly ionizing particles, high energy downgoing muons,
primary cosmic ray composition and shadowing of primary cosmic rays by the Moon
and the Sun.


title: HARP: a hadron production experiment

abstract:
  Hadron production is a key ingredient in many aspects of neutrino physics.
Precise prediction of atmospheric neutrino fluxes, characterization of
accelerator neutrino beams, quantification of pion production and capture for
neutrino factory designs, all of these would profit of high-statistics,
high-precision hadron production measurements. In addition, such data is needed
for the calibration of Monte-Carlo hadron production models. The HARP
experiment at CERN is performing extensive measurements of cross sections and
secondary particle yields to address these problems.


title:
Measurement of Inclusive Jet Cross-Sections in Deep-Inelastic ep
  Scattering at HERA

abstract:
  A measurement of inclusive jet cross-sections in deep-inelastic ep scattering
at HERA is presented based on data with an integrated luminosity of 21.1 pb^-1.
The measurement is performed for photon virtualities Q^2 between 5 and 100
GeV^2, differentially in Q^2, in the jet transverse energy E_T, in E_T^2/Q^2
and in the pseudorapidity eta_lab. With the renormalization scale mu_R = E_T,
perturbative QCD calculations in next-to-leading order (NLO) give a good
description of the data in most of the phase space. Significant discrepancies
are observed only for jets in the proton beam direction with E_T below 20 GeV
and Q^2 below 20 GeV^2. This corresponds to the region in which NLO corrections
are largest and further improvement of the calculations is thus of particular
interest.


title:
Measurement of B(B- to D0 pi-) and B(barB0 to D+ pi-) and Isospin
  Analysis of B to D pi Decays

abstract:
  We present new measurements of branching fractions for the color-favored
decays B^- --> D^0 pi^- and Bbar^0 --> D^+ pi^-. Using 9.67 x 10^6 BBbar pairs
collected with the CLEO detector, we obtain the branching fractions BR(B^- -->
D^0 pi^- =3D (49.7 +/- 1.2 +/- 2.9 +/- 2.2) x 10^{-4} and BR(Bbar^0 --> D^+
pi^- =3D (26.8 +/- 1.2 +/- 2.4 +/- 1.2) x 10^{-4}. The first error is
statistical, the second is systematic, and the third is due to the experimental
uncertainty on the production ratio of charged and neutral B mesons in
Upsilon(4S) decays. These results, together with the current world average for
the color-suppressed branching fraction BR(Bbar^0 --> D^0 pi^0), are used to
determine the cosine of the strong phase difference delta_I between the I=1/2
and I=3/2 isospin amplitudes. We find cos(delta_I) = 0.863 (+0.024 -0.023)
(+0.036 -0.035) (+0.038 -0.030), and obtain a 90% confidence interval of 16.5
degrees < delta_I < 38.1 degrees. This non-zero value of \delta_I strongly
suggests the presence of final state interactions in the Dpi system.


title: Inclusive Diffraction at HERA

abstract:
  The diffractive dissociation of virtual photons, gamma*p -> Xp, has been
studied in ep interactions at HERA with the H1 and ZEUS detectors. The data are
presented in terms of the diffractive structure function F2D and of the
diffractive cross sections dsigma/dt and dsigma/dMX. The t-dependence of the
cross section is measured. The Pomeron intercepts extracted from diffractive
and inclusive ep interactions are compared. The result is further interpreted
studying the dependence of the ratio between the diffractive to the inclusive
cross section on the photon-proton center of mass energy. Recent data on the Q2
dependence of the diffractive cross section at 0.17 < Q2 < 0.70 GeV2 constrain
the transition in diffraction from the perturbative high Q2 region to the
photoproduction limit.


title: Heavy Flavour Production in Two-Photon Collisions at LEP

abstract:
  New results from the experiments ALEPH, DELPHI, L3, and OPAL on heavy quark
production in gammagamma collisions are presented. Inclusive charm and bottom
production are investigated at LEP~2 energies. The total and differential cross
sections for charm quarks are now measured by all four LEP collaborations, the
total bottom by two. Charmonia are studied inclusively via the muonic decay of
the J/psi and separated for the resolved and diffractive processes. New results
are available for exclusive production of the eta_c meson. First searches for
exclusive eta_b production are presented.


title: New Results from K2K

abstract:
  During the first half of the K2K run, data corresponding to 4.8x10^19 POT
were accumulated. In this data set, 56 accelerator-produced neutrino events
were observed in the far detector, while the expected number from the near site
measurements is 80.6+7.3-8.0. This means that the probability of the null-
oscillation scenario is limited to less than 3%. A method for long-baseline
neutrino experiments has been established.


title:
Coverage Of Confidence Intervals For Poisson Statistics In Presence Of
  Systematic Uncertainties

abstract:
  In this note we consider coverage of confidence intervals calculated with and
without systematic uncertainties. These calculations follow the prescription
originally proposed by Cousins & Highland but here extended to account for
different shapes, size and types of systematic uncertainties. Also two
different ordering schemes are considered: the Feldman & Cousins ordering and
its variant where conditioning on the background expectation is applied as
proposed by Roe & Woodroofe. Without uncertainties Feldman & Cousins method
over-covers as expected because of the discreteness of the Poisson
distribution. For Roe & Woodroofe's method we find under-coverage for low
signal expectations. When including uncertainties it becomes important to
define the ensemble for which the coverage is determined. We consider two
different ensembles, where in ensemble A all nuisance parameters are fixed and
in ensemble B the nuisance parameters are varied according to their
uncertainties. We also discuss the subtleties of the realization of the
ensemble with varying systematic uncertainties.


title: Virtual Compton Scattering

abstract:
  Virtual Compton Scattering off the proton: gamma* p to gamma p, is a new
field of investigation of nucleon structure. Several dedicated experiments have
been performed at low c.m. energy and various momentum transfers, yielding
specific information on the proton. This talk reviews the concept of nucleon
Generalized Polarizabilities and the present experimental status.


title: Setting the jet energy scale for the ZEUS calorimeter

abstract:
  A much improved determination of the transverse energy of jets has been
carried out in ZEUS, using a correction procedure based on two independent
methods. The first is based on a combination of tracking and calorimeter
information which optimises the resolution of reconstructed kinematic
variables. The conservation of energy and momentum in neutral current deep
inelastic e^+p scattering events is exploited to determine the energy
corrections by balancing the kinematic quantities of the scattered positron
with those of the hadronic final state. The method has been independently
applied to data and simulated events. The second method uses calorimeter cells
as inputs to the jet algorithm. Simulated events are then used to provide a
correction for the energy loss due to inactive material in front of the
calorimeter. A detailed comparison of the jet transverse energy and the
transverse energy of tracks in a cone around the jet provides the final
correction. This procedure relies on an accurate simulation of charged tracks
and so is less reliant on simulating the energy loss of neutral particles in
inactive material. Final comparisons of the data and simulated events for both
methods allow an uncertainty +/- 1% to be assigned to the jet energy scale.


title: Latest Results from the K2K experiment

abstract:
  The KEK to Kamioka long-baseline neutrino experiment (K2K) is the first
accelerator-based experiment with hundreds of km neutrino path length. K2K
focuses on the study of the existence of neutrino oscillations in $\nu_{\mu}$
disappearance that is observed in atmospheric neutrinos. With nearly pure muon
neutrino beam produced with $5.6\times 10^{19}$ protons from 12 GeV PS on
target, 56 neutrino events have been observed at Super-Kamiokande, the far
detector at 250 km distance. The expectation is $80.6^{+7.3}_{-8.0}$ derived
from the measurement at the near site. The experiment expects to accumulate
$10^{20}$ protons on target, providing sufficient statistics to study neutrino
oscillations by spectral analysis for $\nu_{\mu}$ disappearance.


title: Pion Polarizabilities at CERN COMPASS

abstract:
  The electric alpha and magnetic beta pion Compton polarizabilities
characterize the pion's deformation in the electromagnetic field of the gamma
during gamma-pi Compton scattering. The chi_PT effective Lagrangian, using data
from radiative pion beta decay, predicts the pion electric and magnetic
polarizabilities alpha = -beta = 2.7 +- 0.4. The polarizabilities deduced by
Antipov et al. in their low statistics Primakoff experiment (~ 7000 events)
were about three times larger than this prediction. For pion polarizability,
gamma-pi scattering will be measured in CERN COMPASS via radiative pion
Primakoff scattering (pion Bremsstrahlung) in the nuclear Coulomb field: pi + Z
--> pi' + gamma + Z; equivalent to gamma + pi --> gamma + pi Compton scattering
for laboratory gamma's of order 1 GeV incident on a target pi at rest. The pion
polarizabilities are determined by their effect on the shape of the measured
gamma-pi Compton scattering angular distribution. One can expect from COMPASS a
total measurement uncertainty for alpha, of order 0.4. New high precision pion
polarizability measurements via radiative pion scattering data from COMPASS
will provide important new tests of the QCD chiral dynamics polarizability
prediction.


title: AFB(b) Status of Results

abstract:
  The status of results on forward-backward asymmetry in Z -> bbbar decays is
reviewed. A comparison of LEP measurements, with emphasis on the final ALEPH
measurement with leptons, and a critical discussion of average from heavy
flavour electroweak combination is presented.


title:
photon+jet event rate estimation for the gluon distribution
  determination at the Tevatron Run II

abstract:
  Since a lot of theoretical predictions on the production of new particles
(Higgs, SUSY) at the Tevatron are based on model estimations of the proton
gluon density behavior at low $x$ and high values of a transfered momentum Q^2,
the study of a possibility of a measurement of the gluon density in this
kinematic region directly in Tevatron experiments is obviously of a big
interest [1].
  Basing on the selection criteria proposed ealier in [1,2], the background
events suppression factors and corresponding signal events selection
efficiencies are determined here. The estimation of the number of photon+jet
events suitable for measurement of gluon distribution in different x and Q^2
intervals at Tevatron Run II is also done.
  It is shown that with integrated luminosity L_{int}=3 fb^-1 it would be
possible to collect about one million of these events. This number would allow
to cover a new kinematical region, 10^-3 < x < 1.0 with 1.6*10^3 < Q^2 < 2*10^4
(GeV/c)^2, not studied in any previous experiment. This area includes the
values of Q^2 that are, on the average, by about one order of magnitude higher
than those reached at HERA now. The rates of g c-> photon + jet events are also
obtained.


title:
Tracking Performance of the Scintillating Fiber Detector in the K2K
  Experiment

abstract:
  The K2K long-baseline neutrino oscillation experiment uses a Scintillating
Fiber Detector (SciFi) to reconstruct charged particles produced in neutrino
interactions in the near detector. We describe the track reconstruction
algorithm and the performance of the SciFi after three years of operation.


title: Open Heavy Flavour Production at HERA

abstract:
  Selected recent ZEUS and H1 results on open charm and beauty production in
high energy ep collisions are reviewed. Measurements of differential D* cross
sections, charm meson production ratios and semi-leptonic beauty decays are
discussed and compared with QCD predictions.


title: EIC Detector Studies

abstract:
  The Yale '2000 Workshop detector model is presented. A short summary of the
Interaction Region Group of the EIC Accelerator Workshop is given.


title: The PP2PP Experiment at RHIC

abstract:
  The PP2PP experiment is devoted to the proton-proton elastic scattering
measurement at the Relativistic Heavy Ion Collider at the centre-of-mass
energies between 50 and 500 GeV and the four-momentum transfer $0.0004 \leq |t|
\leq 1.3$ Gev$^2$. The option of polarized proton beams offers a unique
possibility to investigate the spin dependence of the proton elastic scattering
in a systematic way. The energy dependence of the total and elastic cross
section, the ratio of the real to the imaginary part of the forward scattering
amplitude, and the nuclear slope parameter will be studied. In the medium $|t|$
region ($|t| \leq 1.3$ Gev$^2$) the energy dependence of the dip structure in
the elastic differential cross section will be measured. With polarized beams
the measurement of spin dependent observables: the difference of the total
cross sections as function of the of initial transverse spin states, the
analyzing power and the double spin asymmetries will be used to map the $s$ and
$t$ dependence of the proton helicity amplitudes.


title: B Meson Decays: Recent Results from CLEO

abstract:
  The CLEO Collaboration has extracted improved values of |V_cb| and |V_ub|
from measurements of exclusive and inclusive decays of B mesons. The
measurement of B -> D* ell nu at zero recoil combined with the predicted form
factor F_D*(w_min) yields |V_cb|. The photon energy spectrum in b -> s gamma
and the hadronic recoil mass spectrum in B -> X_c ell nu determine
non-perturbative HQET parameters used with inclusive b -> c and b -> u rates to
obtain |V_cb| and |V_ub|.


title: Search for Deconfinement in NA49 at the CERN SPS

abstract:
  Experiment NA49 at the Cern SPS uses a large acceptance detector for a
systematic study of particle yields and correlations in nucleus-nucleus,
nucleon-nucleus and nucleon-nucleon collisions. Preliminary results for Pb+Pb
collisions at 40, 80 and 158 A*GeV beam energy are shown and compared to
measurements at lower and higher energies.


title: The Power of Confidence Intervals

abstract:
  We connect the power of Confidence Intervals in different Frequentist methods
to their reliability. We show that in the case of a bounded parameter a biased
method which near the boundary has large power in testing the parameter against
larger alternatives and small power in testing the parameter against smaller
alternatives is desirable. Considering the recently proposed methods with
correct coverage, we show that the Maximum Likelihood Estimator method has
optimal bias.


title:
Energy dependence of exclusive vector-meson production in ep
  interactions at HERA

abstract:
  The energy dependence of exclusive vector meson (V) production is studied
using the ZEUS data. The SU(4) universality of V cross sections in the
$Q^2+M_V^2$ scale is tested. The energy dependence of the ratio of the cross
sections for V production to the total $\gamma^*p$ cross section is compared
with expectations based on pQCD and Regge approaches.


title: Measurement of the D+ and Ds+ decays into K+K-K+

abstract:
  We present the first clear observation of the doubly Cabibbo suppressed decay
D+ --> K-K+K+ and the first observation of the singly Cabibbo suppressed decay
Ds+ --> K-K+K+. These signals have been obtained by analyzing the high
statistics sample of photoproduced charm particles of the FOCUS(E831)
experiment at Fermilab. We measure the following relative branching ratios:
Gamma(D+ --> K-K+K+)/Gamma(D+ --> K-pi+pi+) = (9.49 +/- 2.17(statistical) +/-
0.22(systematic))x10^-4 and Gamma(Ds+ --> K-K+K+)/Gamma(Ds+ --> K-K+pi+) =
(8.95 +/- 2.12(statistical) +2.24(syst.) -2.31(syst.))x10^-3.

The e+e- -> Z gamma gamma -> q q gamma gamma Reaction at LEP and
  Constraints on Anomalous Quartic Gauge Boson Couplings

abstract:
  The cross section of the process e^+ e^- -> Z \gamma\gamma -> qq \gamma
\gamma is measured with 215 pb^-1 of data collected with the L3 detector during
the final LEP run at centre-of-mass energies around 205 GeV and 207 GeV. No
deviation from the Standard Model expectation is observed. The full data sample
of 713 pb^-1, collected above the Z resonance, is used to constrain the
coefficients of anomalous quartic gauge boson couplings to:
  -0.02 GeV^-2 < a_0/\Lambda^2 < 0.03 GeV^-2 and -0.07 GeV^-2 < a_c/\Lambda^2 <
0.05 GeV^-2, at 95% confidence level.

Measurement of Genuine Three-Particle Bose-Einstein Correlations in
  Hadronic Z decay

abstract:
  We measure three-particle Bose-Einstein correlations in hadronic Z decay with
the L3 detector at LEP. Genuine three-particle Bose-Einstein correlations are
observed. By comparing two- and three-particle correlations we find that the
data are consistent with fully incoherent pion production.

Determination of alphaS from Hadronic Event Shapes in e+e- Annihilation
  at 192 < sqrt(s) < 208 GeV

abstract:
  Results are presented from a study of the structure of high energy hadronic
events recorded by the L3 detector at sqrt(s)>192 GeV. The distributions of
several event shape variables are compared to resummed O(alphaS^2) QCD
calculations. We determine the strong coupling constant at three average
centre-of-mass energies: 194.4, 200.2 and 206.2 GeV. These measurements,
combined with previous L3 measurements at lower energies, demonstrate the
running of alphaS as expected in QCD and yield alphaS(mZ) = 0.1227 +- 0.0012 +-
0.0058, where the first uncertainty is experimental and the second is
theoretical.


title:
Measurements of Charmless Two-Body Charged B Decays with Neutral Pions
  and Kaons

abstract:
  We present preliminary results of the analyses of B into h pi0 and B into hK0
decays (with h = pi+/-, K+/-) from a sample of approximately 60 million BB
pairs collected by the BABAR detector at the PEP-II asymmetric-energy B Factory
at SLAC. We find evidence for a signal in B+ into pi+ pi0, and we measure the
branching fraction BR (B+ into pi+ pi0) = (4.1_{-1.0}^{+1.1}\pm 0.8) 10^{-6}.
We also measure the following branching ratios and charge asymmetries: BR(B+ to
K+ pi0) = (11.1_{-1.2}^{+1.3} \pm 1.0) 10^{-6},
  BR(B+ to pi+ K0) = (17.5^{+1.8}_{-1.7} \pm 1.3)10^{-6}$,
  BR(B+ to K+ K0bar) < 1.3 10^{-6} (90%$ CL), acp_{pi+ pi0} =
-0.02^{+0.27}_{-0.26} \pm 0.10, acp_{K+ pi0} = 0.00\pm 0.11 \pm 0.02$, acp_{pi+
K0} =-0.17\pm 0.10 \pm 0.02, where the errors are statistical and systematic,
respectively.


title: Search for an exotic three-body decay of orthopositronium

abstract:
  We report on a direct search for a three-body decay of the orthopositronium
into a photon and two penetrating particles, o-Ps -> gamma + X1 + X2. The
existence of this decay could explain the discrepancy between the measured and
the predicted values of the orthopositronium decay rate. From the analysis of
the collected data a single candidate event is found, consistent with the
expected background. This allows to set an upper limit on the branching ratio <
4.4 \times 10^{-5} (at the 90% confidence level), for the photon energy in the
range from 40 keV < E_gamma< 400 keV and for mass values in the kinematical
range 0 < mX1+mX2 <900 keV. This result unambiguously excludes the o-Ps ->
gamma + X1 + X2 decay mode as the origin of the discrepancy.


title:
Atmospheric gamma-ray observation with the BETS detectorfor calibrating
  atmospheric neutrino flux calculations

abstract:
  We observed atmospheric gamma-rays around 10 GeV at balloon altitudes (15~25
km) and at a mountain (2770 m a.s.l). The observed results were compared with
Monte Carlo calculations to find that an interaction model (Lund Fritiof1.6)
used in an old neutrino flux calculation was not good enough for describing the
observed values. In stead, we found that two other nuclear interaction models,
Lund Fritiof7.02 and dpmjet3.03, gave much better agreement with the
observations. Our data will serve for examining nuclear interaction models and
for deriving a reliable absolute atmospheric neutrino flux in the GeV region.

New Measurements of the D+ to K*munu/k2pi and Ds to phimunu/phipi
  Branching ratios

abstract:
  Using a large sample of charm semileptonic decays collected by the FOCUS
photoproduction experiment at Fermilab, we present new measurements of two
semileptonic branching ratios. We obtain values of D+ to K*munu/k2pi = 0.602
+/- 0.010 +/- 0.021 and Ds to phimunu/phipi = 0.54 +/- 0.033 +/- 0.048. Our
result D+ result includes the effects of s-wave interference.

Measurement of Analyzing Power for Proton-Carbon Elastic Scattering in
  the Coulomb-Nuclear Interference Region with a 22-GeV/c Polarized Proton Beam

abstract:
  The analyzing power for proton-carbon elastic scattering in the
coulomb-nuclear interference region of momentum transfer,
$9.0\times10^{-3}<-t<4.1\times10^{-2}$ (GeV/$c)^{2}$, was measured with a 21.7
GeV/$c$ polarized proton beam at the Alternating Gradient Synchrotron of
Brookhaven National Laboratory. The ratio of hadronic spin-flip to non-flip
amplitude, $r_5$, was obtained from the analyzing power to be $\text{Re}
r_5=0.088\pm 0.058$ and $\text{Im} r_5=-0.161\pm 0.226$.


title:
Is the Unitarity of the quark-mixing-CKM-matrix violated in neutron
  $\beta$-decay?

abstract:
  We report on a new measurement of neutron $\beta$-decay asymmetry. From the
result \linebreak $A_0$ = -0.1189(7), we derive the ratio of the axial vector
to the vector coupling constant $\lambda$ = ${\it g_A/g_V}$ = -1.2739(19). When
included in the world average for the neutron lifetime $\tau$ = 885.7(7)s, this
gives the first element of the Cabibbo-Kobayashi-Maskawa (CKM) matrix $V_{ud}
$. With this value and the Particle Data Group values for $V_{us}$ and
$V_{ub}$, we find a deviation from the unitarity condition for the first row of
the CKM matrix of $\Delta$ = 0.0083(28), which is 3.0 times the stated error.


title: Selected topics from non-Higgs searches at LEP

abstract:
  Extensive searches for new phenomena have been performed at LEP. The
principal aspects and results of those not related to Higgs bosons are reviewed
here.


title: Standard Model Fits

abstract:
  Recent results of tests of the Standard Model of electroweak interactions are
presented. Data are used from the four LEP experiments, ALEPH, DELPHI, L3,

title:
Search for Charged Excited Leptons in e+e- Collisions at sqrt(s) =
  183-209 GeV

abstract:
  A search for charged excited leptons decaying into a lepton and photon has
been performed using approximately 680 pb-1 of e+e- collision data collected by
the OPAL detector at LEP at centre-of-mass energies between 183 GeV and 209
GeV. No evidence for their existence was found. Upper limits on the product of
the cross-section and the branching fraction are inferred. Using results from
the search for singly produced excited leptons, upper limits on the ratio of
the excited lepton coupling constant to the compositeness scale are calculated.
  From pair production searches, 95% confidence level lower limits on the
masses of excited electrons, muons and taus are determined to be 103.2 GeV.


title: The Rise of the Proton Structure Function F_2 Towards Low x

abstract:
  Results on the derivative of log(F_2) with respect to log(x) at fixed Q^2 are
presented. The measured derivatives are within errors independent of x for Q^2
>= 0.85 GeV^2 and increase linearly with log(Q^2) for 0.0001 <= x <= 0.01 and
Q^2 >= 3 GeV^2.
  The results are based on preliminary and published H1 data which at Q^2 below
2 GeV^2 are combined with NMC and ZEUS data.

Borexino: A real time liquid scintillator detector for low energy solar
  neutrino study

abstract:
  Borexino is a large unsegmented calorimeter featuring 300 tons of liquid
scintillator, contained in a 8.5 meter nylon vessel, viewed by 2200 PMTs. The
main goal of Borexino is the study, in real time, of low energy solar
neutrinos, and in particular, the monoenergetic neutrinos coming from $^7Be$,
which is one of the missing links on the solar neutrino problem. The
achievement of high radiopurity level, in the order of $10^{-16} g/g$ of U/Th
equivalent, necessary to the detection of the low energy component of the solar
neutrino flux, was proved in the Borexino prototype: the Counting Test
Facility. The detector is located underground in the Laboratori Nazionali del
Gran Sasso in the center of Italy at 3500 meter water equivalent depth. In this
paper the science and technology of Borexino are reviewed and its main
capabilities are presented.


title:
Measurements of branching fractions and CP-violating asymmetries in B0
  -> pi+pi-, K+pi-, K+K- decays

abstract:
  We present updated measurements of branching fractions and CP-violating
asymmetries for neutral B meson decays to two-body final states of charged
pions and kaons. The results are obtained from a data sample of about 60
million Y(4S) to BB decays collected between 1999 and 2001 by the BaBar
detector at the Pep-II asymmetric-energy B Factory at SLAC. The sample contains
124+16-15 pipi, 403+-24 Kpi, and 1+8-7 KK candidates, from which we measure the
following quantities:
  B(B0 -> pi+pi-) = (5.4 +- 0.7 +- 0.4) x 10^(-6)
  B(B0 -> K+pi-) = (17.8 +- 1.1 +- 0.8) x 10^(-6)
  B(B0 -> K+K-) < 1.1 x 10^-6 (90% C.L.)
  Kpi asymmetry = -0.05 +- 0.06 +- 0.01, 90% C.L. [-0.14, +0.05]
  Spipi = -0.01 +- 0.37 +- 0.07, 90% C.L. [-0.66, +0.62]
  Cpipi = -0.02 +- 0.29 +- 0.07, 90% C.L. [-0.54, +0.48] where the errors are
statistical and systematic, respectively. These results are preliminary.


title: Light Meson Spectroscopy from Charm Decays

abstract:
  We discuss recent achievements in light scalar mesons spectroscopy through
amplitude analysis of charm particle decay and its consequences. The high
statistics clean samples of charmed mesons, in addition to it's definite J^P
and mass, is turning these decays into a new important environment to study
light meson physics. We give special attention to the scalar sector favored by
a high coupling to charm.


title: sin2phi_2(alpha)) from Belle

abstract:
  We present a measurement of CP-violating asymmetries in B0 -> pi+pi- decays
based on 41.8 fb-1 data sample collected at the Y(4S) resonance with the Belle
detector at the KEKB asymmetric-energy e+e- collider. From the asymmetry in the
distribution of the time intervals between the two B meson decay points, we
obtain the CP-violating asymmetry parameters S_pipi = -1.21 + 0.38 - 0.27
(stat) + 0.16 - 0.13 (syst) and A_pipi = +0.94 + 0.25 - 0.31 (stat) +- 0.09
(syst).


title: Radiative B Decays -- an Experimental Overview

abstract:
  An informal review is given of the status and direction of experiments on
radiative B decays -- b -> s gamma and b -> d gamma. Branching fractions for
exclusive and inclusive b -> s gamma decays, CP asymmetry limits, the photon
energy spectrum, and limits on the b -> d gamma exclusive branching fractions
are covered, and implications of the measurements discussed.

  A review of the experimental results on charmed baryons, with an accent on
those reported most recently. Talk given at FPCP conference, U. Penn, May 2002.


title: A new measurement of the $\Xi_{c}^{0}$ lifetime

abstract:
  Using data collected by the Fermilab experiment FOCUS, we measure the
lifetime of the charmed baryon (\Xi_{c}^{o}) using the decay channels
(\Xi_{c}^{o}\to \Xi ^{-}\pi ^{+}) and (\Xi_{c}^{o}\to \Omega ^{-}K^{+}). From a
combined sample of (110\pm 17) events we find (\tau (\Xi_{c}^{o}) =~118^{+
14}_{- 12} \pm5) fs, where the first and second errors are statistical and
systematic, respectively.


title:
Search for Single Top Production in e+e- Collisions at sqrt(s) up to
  209GeV

abstract:
  Single top production via the flavour changing neutral current reactions e+e-
-> \bar{t}c, \bar{t}u is searched for within the 214 pb-1 of data collected by
ALEPH at centre-of-mass energies between 204 and 209 GeV. No deviation from the
Standard Model expectation is observed and upper limits on the single top
production cross sections are derived. The combination with data collected at
lower centre-of-mass energies yields an upper limit on the branching ratio BR(t
-> Zc)+BR(t -> Zu) 14%, for BR(t -> \gamma c)+BR(t -> \gamma u)= 0 and mt=174
GeV/c2.


title: Concluding remarks on QCD-N'02 Workshop at Ferrara

abstract:
  A summary is given of some important developments in QCD studies of the
nucleon as presented at this workshop. Based on these developments some
expectations for the short- and long-term future of the field are sketched.
Taken together, the summary of the workshop and the future perspectives result
in a {\sl Road Map} for experimental studies of the QCD structure of the
nucleon. The Road Map includes as a long-term goal the construction of new
lepton-hadron scattering facilities both in Europe and the United States.

charged and neutral K-> pi nu nubar channels, is presented along with prospects
for future measurements.


title:
Search for Odderon-Induced Contributions to Exclusive pi^0
  Photoproduction at HERA

abstract:
  A search for contributions to the reaction ep-> e pi^0 N^* from
photon-Odderon fusion in the photoproduction regime at HERA is reported, at an
average photon-proton centre-of-mass energy <W> = 215 GeV. The measurement
proceeds via detection of the pi^0 decay photons, a leading neutron from the
N^* decay, and the scattered electron. No pi^0 signal is observed and an upper
limit on the cross section for the photon-Odderon fusion process of sigma(gamma
p -> pi^0 N^*) < 49 nb at the 95% confidence level is derived, integrated over
the experimentally accessible range of the squared four-momentum transfer at
the nucleon vertex 0.02 < |t| < 0.3 Gev^2. This excludes a recent prediction
from a calculation based on a non-perturbative QCD model of a photon-Odderon
fusion cross section above 200 nb.


title: Performance of the OPAL Si-W luminometer at LEP I-II

abstract:
  A pair of compact Silicon-Tungsten calorimeters was operated in the OPAL
experiment at LEP to measure the integrated luminosity from detection of Bhabha
electrons scattered at angles between 25 and 58 mrad from the beam line. In the
eight years from 1993 to 2000 the detector worked first at the Z mass peak and
then at center of mass energies up to 209 GeV. The fine radial and longitudinal
segmentation (2.5mm x 1X0) allowed the radial position of electron and photon
showers to be measured with a resolution of 130-170 microns and a residual
radial bias as small as 7 microns. Reducing the bias in the definition of the
inner acceptance radius was the key element in obtaining an experimental
systematic error on the integrated luminosity of only 3.4 10^-4. The
performance of the detector at both LEP-I and LEP-II is reviewed. Energy
resolution, sensitivity to overlapping electromagnetic showers and sensitivity
to minimum ionizing particles are discussed.


title: Light Scalar Mesons in Charm Decays

abstract:
  We present recent results on scalar light mesons based on Dalitz plot
analyses of charm decays from Fermilab experiment E791. Low mass scalar mesons
are found to have large contributions to the decays studied, D^+\to
K^-\pi^+\pi^+ and D^+, D_s^+\to\pi^-\pi^+\pi^+. These results demonstrate the
importance of charm decays as a new environment for the study of light meson
physics.


title: Nuclear Propelled Vessels and Neutrino Oscillation Experiments

abstract:
  We study the effect of naval nuclear reactors on the study of neutrino
oscillations. We find that the presence of naval reactors at unknown locations
and times may limit the accuracy of future very long baseline reactor-based
neutrino oscillation experiments. At the same time we argue that a nuclear
powered surface ship such as a large Russian ice-breaker may provide an ideal
source for precision experiments. While the relatively low reactor power would
in this case require a larger detector, the source could be conveniently
located at essentially any distance from a detector built at an underground
location near a shore in a region of the world far away from other nuclear
installations. The variable baseline would allow for a precise measurement of
backgrounds and greatly reduced systematics from reactor flux and detector
efficiency. In addition, once the oscillation measurement is completed, the
detector could perform geological neutrino and astrophysical measurements with
minimal reactor background.


title: XXXVIIi\'eme Rencontres de Moriond: Electroweak 2002 Conference Summary

abstract:
  A substantial body of data is described by the Standard Model of particle
physics. However the description is far from perfect and there is a growing
number of internal inconsistencies. These fall short of qualifying as
discoveries; nevertheless, examination of their merits is both interesting and
worthwhile. The existence of three families of quarks and leptons is not
understood. There are new data, especially from the B factories; the latter are
shining new light on the problem. From several experiments, data show that our
thoughts about the existence of transitions between neutrino flavors,
oscillations, may be correct but the understanding of the patterns needs work.
However, we see the opening of a number of avenues of investigation as new
facilities and experiments come online.

  Evidence for the inclusive $B \to X_s \ell^+ \ell^-$ decay has been presented
based on 41.8 fb-1 data sample collected at the Y(4S) resonance with the Belle
detector at the KEKB asymmetric e+e- collider. A preliminary result for the
branching fraction is B($B \to X_s \ell^+ \ell^-$) = (7.1 +- 1.6 (stat.) + 1.4
- 1.2(syst.)) \times 10^-6.


title: Statistical practice at the Belle experiment, and some questions

abstract:
  The Belle collaboration operates a general-purpose detector at the KEKB

beauty, charm, tau and 2-photon physics. In this paper, the treatment of
statistical problems in past and present Belle measurements is reviewed. Some
open questions, such as the preferred method for quoting rare decay results,
and the statistical treatment of the new B0/B0bar --> pi+ pi- analysis, are
discussed.


title: Study of B -> \rho \pi decays at Belle

abstract:
  This paper describes a study of B meson decays to the pseudoscalar-vector
final state \rho\pi using 31.9\times 10^6 B\bar{B} events collected with the
Belle detector at KEKB. The branching fractions B(B^+ \to \rho^0\pi^+) =
(8.0^{+2.3+0.7}_{-2.0-0.7}) \times 10^{-6} and B(B^0 -> \rho^{+-} \pi^{-+}) =
(20.8^{+6.0+2.8}_{-6.3-3.1}) \times 10^{-6} are obtained. In addition, a 90%
confidence level upper limit of B(B^0 \to \rho^0\pi^0) < 5.3 \times 10^{-6}is
reported.


title: Tests of Chiral Perturbation Theory in Rare Kaon Decays

abstract:
  The neutral Kaon decays Ks->gamma gamma and Kl->pi0 gamma gamma are very
sensitive to higher order loop effects of Chiral Perturbation Theory (ChPT).
New measurements of the NA48 experiment show that ChPT contributions of O(p^6)
cannot be neglected in these modes. In addition a new measurement of the
related decay Kl->gamma gamma and an upper limit of the rate of Ks->pi0 gamma
gamma are presented.

presented.


title: New BaBar Results on Rare Leptonic B Decays

abstract:
  New preliminary BaBar results for rare leptonic decays $B^- \to K^-\nu
\bar{\nu}$ and $B^0\to \ell^+\ell^-$ are reported. Using data collected at the
$\FourS$ with the BaBar detector, no evidence for a signal was found yielding
the corresponding upper limits at the 90% confidence level: ${\cal B}(B^-\to
K^-\nu \bar{\nu})< 9.4 \times 10^{-5}$ for $50.7 \invfb $, ${\cal B}(\bee)<
\eeul$, ${\cal B}(\bmm) < \mmul$ and ${\cal B}(\bem) < \emul$ using $54.4
\invfb $.


title: Diffractive Rho Meson Electroproduction at High Q^2 and High |t|

abstract:
  The electroproduction of rho mesons is studied at HERA with the H1 detector
at high Q^2 and high |t|. Cross sections are measured as a function of Q^2, W
and t. The W dependence of the gamma*-p cross section is observed to increase
with Q^2 from values compatible with soft Pomeron exchange at low Q^2 to a hard
dependence at large Q^2. Spin density matrix elements are measured and their
dependence is compared with a two gluon exchange model.


title: Studies of the Decay B+- -> D_CP K+-

abstract:
  We report studies of the decay B+- -> D_CP K+-, where D_CP denotes neutral D
mesons that decay to CP eigenstates. The analysis is based on a 29.1/fb data
sample of collected at the \Upsilon(4S) resonance with the Belle detector at
the KEKB asymmetric e+ e- storage ring. Ratios of branching fractions of
Cabibbo-suppressed to Cabibbo-favored processes involving D_CP are determined
to be B(B- -> D_1 K-)/B(B- -> D_1 pi-)=0.125 +- 0.036 +- 0.010 and B(B- -> D_2
K-)/B(B- -> D_2 pi-)=0.119 +- 0.028 +- 0.006, where indices 1 and 2 represent
the CP=+1 and CP=-1 eigenstates of the D0 - anti D0 system, respectively. We
also extract the partial rate asymmetries for B+- -> D_CP K+-, finding A_1 =
0.29 +- 0.26 +- 0.05 and A_2 = -0.22 +- 0.24 +- 0.04.

New results on nuclear dependence of J/psi and psi' production in 450
  GeV pA collisions

abstract:
  To understand the reliability of the charmonia suppression as a signature of
the Quark-Gluon Plasma formation in nucleus-nucleus collisions it is important
first to understand the details of the production of J/psi and psi' in pA
interactions and the difference in the suppression of these two states. This
report presents the results of the study by the NA50 collaboration of the J/psi
and psi' production in pA interactions at 450 GeV beam energy and its
dependence on rapidity. It is shown that the psi' suffers more suppression than
the J/psi, which is consistent with a similar observation made at 800 GeV beam
energy by the E866/NuSea collaboration.


title: Rare Decays, Recent Results from FOCUS (+Theory)

abstract:
  We present results for 3 body rare decays of the D+ and Ds+ containing 2
muons from the FOCUS experiment. A comparison to previous best experimental
limits and theory is also shown.


title: The Generalized Parton Distributions program at Jefferson Lab

abstract:
  The Generalized Parton Distributions (GPD) have drawn a lot of interest from
the theoretical community since 1997, but also from the experimental community
and especially at Jefferson Lab. First, the results for Deeply Virtual Compton
Scattering (DVCS) at 4.2 GeV beam energy have recently been extracted from CLAS
data. The single spin asymmetry shows a remarkably clean sine wave despite the
rather low Q2 achievable at this energy. Two new dedicated DVCS experiments
using 6 GeV beam will run in 2003 and 2004 in Hall A and Hall B respectively.
Both experiments will yield very accurate results over a wide range of
kinematics, and allow for the first time a precise test of the factorization of
the DVCS process. Assuming the Bjorken regime is indeed reached, these
experiments will allow the extraction of linear combinations of GPD's and put
strong constraints on the available phenomenological models. Upon successful
completion of both experiments, a wider experimental program at 6 GeV can be
envisioned, using for instance Deuterium targets trying to nail down the
neutron and deuteron GPD's. In addition, resonances can be probed using
DeltaVCS where one produces a resonance in the final state. Finally, the 12 GeV
upgrade of Jefferson Lab extends the available kinematical range, and will
allow us to perform a complete, high precision GPD program using various
reactions among which, Deeply Virtual Meson Electroproduction (DVMP) and DVCS.


title: The CDF MiniPlug Calorimeters

abstract:
  Two MiniPlug calorimeters, designed to measure the energy and lateral
position of particles in the (forward) pseudorapidity region of
$3.6<|\eta|<5.2$ of the CDF detector, have been recently installed as part of
the Run II CDF upgrade at the Tevatron $\bar pp$ collider. They consist of
lead/liquid scintillator read out by wavelength shifting fibers arranged in a
pixel-type towerless geometry suitable for `calorimetric tracking'. The design
concept, the prototype performance and the final design of the MiniPlugs are
here described. A recent cosmic ray test resulted in a light yield of
approximately 100 pe/MIP, which exceeds our design requirements.


title: Dijet Production at Low Q2

abstract:
  Triple differential dijet cross-sections in electron proton interactions
measured with the H1 detector at HERA are presented. The data are compared to
Monte Carlo simulations based on the DGLAP and CCFM parton evolution schemes.
Effects of longitudinally polarized virtual photons are investigated.


title: Observation of B+- -> omega K+- Decay

abstract:
  We report the first observation of the charmless two-body mode $B^{\pm} \to
\omega K^{\pm}$ decay, and a new measurement of the branching fraction for the
$B^{\pm} \to \omega \pi^{\pm}$ decay. The measured branching fractions are
${\cal B} (B^{\pm} \to \omega K^{\pm}) =
  (9.2{}^{+2.6}_{-2.3}\pm 1.0) \times 10^{-6}$ and ${\cal B} (B^{\pm} \to
\omega \pi^{\pm}) =
  (4.2{}^{+2.0}_{-1.8}\pm 0.5) \times 10^{-6}$. %and we set 90% confidence
level upper limits of %${\cal B} (B^- \to \omega \pi^-) < 8.1\times 10^{-6}$.
We also measure the partial rate asymmetry of $B^{\pm}\to\omega K^{\pm}$ decays
and obtain ${\cal A}_{CP} = -0.21 \pm 0.28 \pm 0.03$. The results are based on
a data sample of 29.4 fb$^{-1}$ collected on the $\Upsilon(4S)$ resonance by
the Belle detector at the KEKB $e^{+} e^{-}$ collider.


title: Final results of magnetic monopole searches with the MACRO experiment

abstract:
  We present the final results obtained by the MACRO experiment in the search
for GUT magnetic monopoles in the penetrating cosmic radiation, for the range
$4\times 10^{-5}< \beta < 1$. Several searches with all the MACRO sub-detectors
(i.e. scintillation counters, limited streamer tubes and nuclear track
detectors) were performed, both in stand alone and combined ways. No candidates
were detected and a 90% Confidence Level (C.L.) upper limit to the local
magnetic monopole flux was set at the level of $1.4\times 10^{-16}$ cm$^{-2}$
s$^{-1}$ sr$^{-1}$. This result is the first experimental limit obtained in
direct searches which is well below the Parker bound in the whole $\beta$ range
in which GUT magnetic monopoles are expected.

CompAZ: parametrization of the luminosity spectra for the photon
  collider

abstract:
  A simple model, based on the analytical formula for the Compton scattering,
is proposed to describe the realistic photon-energy spectra for the Photon
Collider at TESLA. Parameters of the model are obtained from the full
simulation of the beam by V.Telnov, which includes nonlinear corrections and
contributions of higher order processes. Photon energy distribution and
polarization, in the high energy part of the spectra, are well reproduced. Our
model can be used for a Monte Carlo simulation of gamma-gamma events at various
energies and for direct cross-section calculations.

Measurement of the Oscillation Frequency for B0-Bobar Mixing using
  Hadronic B0 Decays

abstract:
  The oscillation frequency of B0-B0bar mixing (Delta-m_d) has been measured
using 29.1 fb^{-1} of datacollected with the Belle detector at KEKB. This
measurement is made through the distributions of the proper decay time
difference of B pairs in events tagged as same- and opposite-flavor decays. In
each event, one $B$ is fully reconstructed in a flavor-specific hadronic decay
mode, while the flavor of the other is extracted through a likelihood
calculated from the b-flavor information carried in its final decay products.
We obtain Delta-m_d = (0.528 +- 0.017 +- 0.011) ps^{-1}, where the first error
is statistical and the second error is systematic.


abstract:
  Charm fragmentation and dijet angular distributions have been measured in
$D^*$ photoproduction at HERA. Charm fragmentation and its property of
universality is evaluated in terms of measurement of $P_v$, the ratio of
vector/(vector + pseudoscalar) mesons. Angular distributions of dijets, with at
least one of the jets associated with a $D^{*\pm}$ meson, have been measured
for samples enriched in direct or resolved photon events. The differential
cross section shows a steep rise for resolved events in the photon direction,
providing strong evidence that the bulk of the resolved photon cross section is
due to the charm content of the photon. The shallower rise for direct events as
well as for resolved photon events in the proton direction are consistent with
the quark exchange diagrams.


title:
Search for Nucleon Decays induced by GUT Magnetic Monopoles with the
  MACRO Experiment

abstract:
  The interaction of a Grand Unification Magnetic Monopole with a nucleon can
lead to a barion-number violating process in which the nucleon decays into a
lepton and one or more mesons (catalysis of nucleon decay). In this paper we
report an experimental study of the effects of a catalysis process in the MACRO
detector. Using a dedicated analysis we obtain new magnetic monopole (MM) flux
upper limits at the level of $\sim 3\cdot 10^{-16} cm^{-2} s^{-1} sr^{-1}$ for
$1.1\cdot 10^{-4} \le |\beta| \le 5\cdot 10^{-3}$, based on the search for
catalysis events in the MACRO data. We also analyze the dependence of the MM
flux limit on the catalysis cross section.


title: Total gamma-N cross section in the energy range sqrt(s)=40-250 GeV

abstract:
  The results of measurements of gamma-N total cross section, obtained by the
method of photoproduction processes registration at the Baksan Underground
Scintillation Telescope, are presented. These data at energies sqrt(s)=40-130
GeV confirm the effect of more rapid photon-hadron cross-section rise as
compared to the hadron-hadron ones. It is shown, the increasing of the additive
quark number in the products of photon hadronization can be one of the causes
responsible for this effect. On the basis of the analysis of experimental data
on both gamma-N and gamma-gamma total cross sections, the status of direct and
indirect cross-section measurements is discussed.


title: Systematic Errors: facts and fictions

abstract:
  The treatment of systematic errors is often mishandled. This is due to lack
of understanding and education, based on a fundamental ambiguity as to what is
meant by the term. This note addresses the problems and offers guidance to good
practice.


title:
Search for Associated Production of Massive States Decaying into Two
  Photonsin e+e- Annihilations at sqrt(s) = 88-209 GeV

abstract:
  A search is performed for production of short-lived particles in e+e- -> XY,
with X -> gamma gamma and Y -> ffbar, for scalar X and scalar or vector Y.
Model-independent limits in the range of 25-60 femtobarns are presented on
sigma (e+e- -> XY) x B(X -> ffbar) for centre-of-mass energies in the range
205-207 GeV. The data from all LEP centre-of-mass energies 88-209 GeV are also
interpreted in the context of fermiophobic Higgs boson models, for which a
lower mass limit of 105.5 GeV is obtained for a "benchmark" fermiophobic Higgs
boson.


title:
On the application of 'photon+jet' events for setting the absolute jet
  energy scale and determining the gluon distribution at the LHC

abstract:
  We study the impact 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 LHC. 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 Pt with jet Pt and would
allow to reduce the background are described. The distributions of these events
over photon Pt and jet pseudorapidity are presented. The features of
'photon+jet' events in the barrel region of the CMS detector (|eta^{jet}| <
1.4) 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 > 2*10^{-4} and of Q^2 by
two orders higher than that studied at HERA.


title: Beam-Charge Asymmetry associated with DVCS at HERMES

abstract:
  We report the first observation of an azimuthal asymmetry in the hard
electroproduction of real photons with respect to the charge of the incoming
lepton beam. The asymmetry is attributed to the interference between the
Bethe-Heitler process and the deeply-virtual Compton scattering process, which
gives access to the latter at the amplitude level. This process appears to be
the theoretically cleanest way to access generalized parton distributions. The
data have been accumulated by the HERMES experiment at DESY, scattering the
HERA 27.6 GeV electron/positron beam off an unpolarized hydrogen gas target.


title: Deeply Virtual Compton Scattering at H1 and ZEUS

abstract:
  Results on Deeply Virtual Compton Scattering at HERA measured by the H1 and
ZEUS Collaborations are presented. The cross section, measured for the first
time, is reported for by H1 and ZEUS for $Q^2$ above a few GeV$^2$ in the low
$x$ region. The measured cross section is discussed and compared to different
predictions.

Recent Progress in Neutrino Factory and Muon Collider Research within
  the Muon Collaboration

abstract:
  We describe the status of our effort to realize a first neutrino factory and
the progress made in understanding the problems associated with the collection
and cooling of muons towards that end. We summarize the physics that can be
done with neutrino factories as well as with intense cold beams of muons. The
physics potential of muon colliders is reviewed, both as Higgs Factories and
compact high energy lepton colliders. The status and timescale of our research
and development effort is reviewed as well as the latest designs in cooling
channels including the promise of ring coolers in achieving longitudinal and
transverse cooling simultaneously. We detail the efforts being made to mount an
international cooling experiment to demonstrate the ionization cooling of
muons.


title: Search for excited fermions in ep collisions at HERA

abstract:
  Heavy excited electrons and neutrinos have been sought by the H1 and ZEUS
experiments at HERA. For the e* (nu*) searches, 120 pb^-1 (16 pb^-1) of ep
collision data have been analysed. No evidence for any excited lepton has been
found, and limits on the characteristic couplings have been derived.


title: Measurement of CP-Violating Parameters in $B\to \eta^\prime K$ Decays

abstract:
  We present measurements of CP-violating parameters in $B^0(\bar{B}{}^0) \to
\eta^\prime K_S^0$ and $B^{\pm} \to \eta' K^{\pm}$ 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 $B^0(\bar{B}{}^0) \to \eta^\prime K_S^0$
CP eigenstate and identify the flavor of the accompanying $B$ from its decay
products. From the distribution of time intervals between pairs of $B$ meson
decay points, we obtain the CP-violating asymmetry parameters ${\mathcal
S}_{\eta^\prime K_S^0} = 0.28\pm0.55(stat)^{+0.07}_{-0.08}(syst)$, and
${\mathcal A}_{\eta^\prime K_S^0} = 0.13\pm0.32(stat)^{+0.09}_{-0.06}(syst)$.
We also reconstruct charged $B^{\pm} \to \eta^\prime K^{\pm}$ decays and
determine a direct-CP violating asymmetry value of ${\mathcal A}_{\eta^\prime
K^\pm}=(-1.5\pm7.0(stat)\pm0.9(syst))%$.


title:
photon+jet process application for setting the absolute scale of jet
  energy and determining the gluon distribution at the LHC

abstract:
  The possibility of jet energy scale setting at the CMS calorimeter by using
photon+jet process is studied.
  The estimation of the number of photon+jet events suitable for determination
of gluon distribution inside a proton in a new kinematic region of x, Q^2
variables beyond the one covered by HERA data is also presented.


title: CP Violation in Charm

abstract:
  Recent results on searches for CP and CPT violation in the charm sector are
presented. These results include limits on direct CP violation in several
channels from the FOCUS and CLEO experiments. The first reported search for CPT
violation in charm, a preliminary result by the FOCUS collaboration, is also
presented.


title: Neutrino Factory Designs and R&D

abstract:
  European, Japanese, and US Neutrino Factory designs are presented. The main
R&D issues, and the associated R&D programs, are discussed.


title: Electroweak Results from NuTeV

abstract:
  The NuTeV collaboration has extracted the electroweak parameter, $\stw$, from
the measurement of the ratios of neutral current to charged current neutrino
and antineutrino deep inelastic scattering interactions. We find that our
measurement, while in agreement with previous neutrino electroweak
measurements, is not consistent with the prediction from global electroweak
fits. To facilitate interpretation of the result, a model independent analysis
is presented and possible explanations are discussed


title: Search for Excited Electrons at HERA

abstract:
  A search for excited electron e* production is described in which the
electroweak decays e*->e gamma, e*->e Z and e*->nu W are considered. The data
used correspond to an integrated luminosity of 120 pb^(-1) taken in e^(+-)p
collisions from 1994 to 2000 with the H1 detector at HERA at centre-of-mass
energies of 300 and 318 GeV. No evidence for a signal is found. Mass dependent
exclusion limits are derived for the ratio of the couplings to the
compositeness scale, f/Lambda. These limits extend the excluded region to
higher masses than has been possible in previous direct searches for excited
electrons.

  This document describes a Monte-Carlo simulation of an underwater neutrino
telescope with a homogeneous detection volume of a cubic kilometre.


title:
The Investigations Of Beam Extraction And Collimation At U-70 Proton
  Synchrotron Of IHEP By Using Short Silicon Crystals

abstract:
  The new results of using short (2-4mm) bent crystals for extraction and
collimation of proton beam at IHEP 70 Gev proton synchrotron are reported. A
broad range of energies from 6 to 65 GeV has been studied in the same crystal
collimation set-up. The efficiency of extraction more than 85% and intensity
more than 10E12 were obtained by using crystal with the length 2-mm and the
angle 1 mrad. The new regime of extraction is applied now at the accelerator to
deliver the beam for different experimental setups within the range of
intensity 10E7-10E12ppp.


title: Observation of B -> D^{(*)} K^- K^{0(*)} decays

abstract:
  The B -> D^{(*)} K^- K^{(*)0} decays have been observed for the first time.
The branching fractions of the B -> D^{(*)} K^- K^{(*)0} decay modes are
measured. Significant signals are found for the B -> D^{(*)} K^- K^{*0} and B^-
-> D^0 K^- K^0_S decay modes. The invariant mass and polarization distributions
for the K^-K^{*0} and K^-K^0_S subsystems have been studied. For the K^-K^{*0}
sybsystem these distributions agree well with those expected for two-body B ->
D^{(*)} a_1^-(1260) decays, with a_1^-(1260) -> K^- K^{*0}. The analysis was
done using 29.4 fb^{-1} of data collected with the Belle detector at the e^+
e^- asymmetric collider KEKB.


title: Measurement of the CP-Violating Asymmetry Amplitude sin2beta

abstract:
  We present results on time-dependent CP-violating asymmetries in neutral B
decays to several CP eigenstates. The measurements use a data sample of about
88 million Y(4S) --> B Bbar decays collected between 1999 and 2002 with the
BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. We study
events in which one neutral B meson is fully reconstructed in a final state
containing a charmonium meson and the other B meson is determined to be either
a B0 or B0bar 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 = 0.741
+/- 0.067 (stat) +/- 0.034 (syst) and |lambda| = 0.948 +/- 0.051 (stat) +/-
0.030 (syst). The magnitude of lambda is consistent with unity, in agreement
with the Standard Model expectation of no direct CP violation in these modes.


title:
Measurement of the residual energy of muons in the Gran Sasso
  underground Laboratories

abstract:
  The MACRO detector was located in the Hall B of the Gran Sasso underground
Laboratories under an average rock overburden of 3700 hg/cm^2. A transition
radiation detector composed of three identical modules, covering a total
horizontal area of 36 m^2, was installed inside the empty upper part of the
detector in order to measure the residual energy of muons. This paper presents
the measurement of the residual energy of single and double muons crossing the
apparatus. Our data show that double muons are more energetic than single ones.
This measurement is performed over a standard rock depth range from 3000 to
6500 hg/cm^2.


title: Experimental Status of K -> pi nu nu_bar

abstract:
  The experimental program for the study of the rare kaon decays, K -> pnn, is
summarized. A review of recent results is provided along with a discussion of
prospects for the future of this program. The primary focus of the world-wide
kaon program is the two golden modes: K+ -> pnn and KL -> pnn. The first step
in an ambitious program to precisely measure both branching ratios has been
successfully completed with the observation of two K+ -> pnn events by E787.
The E949 experiment is poised to reach an order of magnitude further in
sensitivity and to observe ~10 Standard Model events, and the CKM experiment
should observe ~100 SM events by the end of this decade. Limits on the neutral
analog KL -> pnn have been set by KTeV and within the next couple of years will
be pushed by E391a. Measurements of the branching ratio should be made within
the next 10 years by KOPIO, with a goal of ~50 events, and at the JHF, with a
goal of up to 1000 events.


title:
Mesurement of the B0 - anti-B0 Mixing Parameter Delta m_d using
  Semileptonic B0 Decays

abstract:
  We present a measurement of the B^0-B^0bar mixing parameter Delta m_d using
neutral B meson pairs in a 29.1 fb^{-1} data sample collected at the
Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy
e^+e^- collider. We exclusively reconstruct one neutral B meson in the
semileptonic B^0 \to D^{*-}\ell^+\nu decay mode and identify the flavor of the
accompanying B meson from its decay products. From the distribution of the time
intervals between the two flavor-tagged B meson decay points, we obtain Delta
m_d = (0.494 +- 0.012 +- 0.015) ps^{-1}, where the first error is statistical
and the second error is systematic.


title:
Multiple Jet Production at Low Transverse Energies in p-pbar Collisions
  at Root(s) = 1.8 TeV

abstract:
  We present data on multiple production of jets with transverse energies near
20 GeV in p-pbar collisions at Root(s) = 1.8 TeV. QCD calculations in the
parton-shower approximation of PYTHIA and HERWIG and the next-to-leading order
approximation of JETRAD are compared to the data for one, two, three, and four
jet inclusive production. Transverse energy spectra and multiple jet angular
and summed transverse-energy distributions are adequately described by the
shower approximation while next-to-leading order calculations describe the data
poorly.


title:
Results on Lambda and Xi production in Pb-Pb collisions at 160 GeV/c per
  nucleon from the NA57 experiment

abstract:
  The NA57 experiment has been designed to study the onset of enhanced
production of strange baryons and anti-baryons in Pb-Pb collisions with respect
to p-Be collisions. This enhancement is considered a sensitive signature for a
phase transition to a new state of matter -- the Quark Gluon Plasma (QGP). In
this paper, we report results on Lambda and Xi hyperon production in central
Pb-Pb collisions at 160 GeV/c per nucleon beam momentum.


title:
A Search for Time-Dependent B0s-B0sbar Oscillations Using Exclusively
  Reconstructed Ds+/- Mesons

abstract:
  A search for Bs0-Bs0bar oscillations is performed using a sample of 400,000
hadronic Z0 decays collected by the SLD experiment. The Bs0 candidates are
reconstructed in the Bs0 to Ds-,X channel with Ds- to phi,pi- or K*0K-. The Bs0
production flavor is determined using the large forward-backward asymmetry of
polarized Z0 to b,bbar decays and charge information in the hemisphere opposite
that of the Bs0 candidate. The decay flavor is tagged by the charge of the
Ds+/-. From a sample of 361 candidates with an average Bs0 purity of 40%, we
exclude the following values of the oscillation frequency: Delta m_s < 1.4
ps^{-1} and 2.4 < Delta m_s < 5.3 ps^{-1} at the 95% confidence level.


title: New Measurements of the D+ to K* mu nu Form Factor Ratios

abstract:
  Using a large sample of D+ to K- pi+ mu+ nu decays collected by the FOCUS
photoproduction experiment at Fermilab, we present new measurements of two
semileptonic form factor ratios: rv and r2. We find rv = 1.504 \pm 0.057 \pm
0.039 and r2 = 0.875 \pm 0.049 \pm 0.064. Our form factor results include the
effects of the s-wave interference discussed in a previous paper.


title: Higgs Searches at LEP

abstract:
  The four LEP experiments ALEPH, DELPHI, L3 and OPAL have performed decay-mode
independent searches for scalar bosons, flavour-independent Higgs boson
searches, searches for Higgs bosons in the Standard Model and several
Two-Higgs-Doublet models and searches for doubly charged Higgs bosons at
centre-of-mass energies up to 209 GeV. The results obtained and mostly combined
by the LEP Higgs working group are discussed.


title: Magnetic monopole searches in the cosmic radiation

abstract:
  There has been a big effort in the past twenty years with at least a couple
of generations of experiments which searched for supermassive GUT magnetic
monopoles in the cosmic radiation.
  Here a short review of these searches is given, together with a brief
description of the theoretical framework and of the detection techniques.


title:
Reply to the Comment on "A Precise Determination of Electroweak
  Parameters in Neutrino-Nucleon Scattering"

abstract:
  In a recent comment, Miller and Thomas assert that differences in nuclear
shadowing effects between neutrino neutral current (NC) and charged current
(CC) interactions could explain the difference between NuTeV's measurement of
the weak mixing angle and the prediction from other electroweak data. We argue
that the proposed effect could have only a small impact on sin2thetaW derived
from the Paschos-Wolfenstein R- and that such an effect is strongly disfavored
by the neutrino and anti-neutrino NC-to-CC cross-section ratios also measured
by NuTeV.


title: A Study of The Rare Decays B0 -> Ds(*)+ pi- and B0 -> Ds(*)-K+

abstract:
  We report on the evidence for the decays B0 -> Ds+ pi- and B0 -> Ds- K+ and
the results of a search for the decays B0 -> Ds*+ pi- and B0 -> Ds*-K+ from a
sample of 84 million Upsilon(4S) decays into B meson pairs collected with the
BABAR detector at the PEP II asymmetric-energy e^{+}e^{-} collider.
  The measured B0 -> Ds+ pi- yield has a probability of less than 10^{-3} to be
a fluctuation of the background and we measure the branching fraction Br(B0 ->
Ds+ pi-) = (3.2 +- 0.9 (stat) +- 1.0 (syst)) x 10^-5. The measured B0 -> Ds- K+
yield has a probability of less than 5 times 10^{-4} to be a fluctuation of the
background and we measure the branching fraction Br(B0 -> Ds- K+) = (3.2 +- 1.0
(stat) +- 1.0 (syst)) x 10^-5. We also set 90% C.L. limits Br(B0 -> Ds*+ pi-)<
4.1 x 10^-5 and Br(B0 -> Ds*- K+) < 2.5 x 10^-5. All results are preliminary


title:
Search for charged Higgs bosons in e+e- collisions at energies up to
  sqrt(s) = 209GeV

abstract:
  A search for charged Higgs bosons produced in pairs is performed with data
collected at centre-of-mass energies ranging from 189 to 209 GeV by ALEPH at
LEP, corresponding to a total luminosity of 629 invpb. The three final states
taunutaunu, taunucs and cscs are considered. No evidence for a signal is found
and lower limits are set on the mass M_H+ as a function of the branching
fraction B(H to taunu). In the framework of a two-Higgs-doublet model, and
assuming B(H+ to taunu + B(H+ to cs) = 1 charged Higgs bosons with masses below
79.3 Gev/c2 are excluded at 95% confidence level independently of the branching
ratios.


title:
Measurements of Branching Fractions and CP-violating Asymmetries in
  B0->pi+ pi-, K+ pi-, K+ K- Decays

abstract:
  We present measurements of branching fractions and CP-violating asymmetries
for neutral B meson decays to two-body final states of charged pions and kaons
based on a sample of about 88 million Y(4S)-->BB decays. From a
time-independent fit we measure the charge-averaged branching fractions
B(B0-->pi+pi-) = (4.7 +/- 0.6 +/- 0.2) x 10^-6, B(B0-->K+pi-) = (17.9 +/- 0.9
+/- 0.7) x 10^-6, and the direct CP-violating charge asymmetry A(Kpi) = -0.102
+/- 0.050 +/- 0.016; [-0.188,-0.016], where the ranges in square brackets
indicate the 90% confidence intervals. From a time-dependent fit we measure the
B0-->pi+pi- CP-violating parameters Spipi = 0.02 +/- 0.34 +/- 0.05;
[-0.54,+0.58] and Cpipi = -0.30 +/- 0.25 +/- 0.04; [-0.72,+0.12].


title:
Absolute Lower Limits on the Masses of Selectrons and Sneutrinos in the
  MSSM

abstract:
  The results of searches for selectrons, charginos and neutralinos performed
with the data collected by the ALEPH detector at LEP at centre-of-mass energies
up to 209 GeV are interpreted in the framework of the Minimal Supersymmetric
extension of the Standard Model with R-parity conservation. Under the
assumptions of gaugino and sfermion mass unification and no sfermion mixing, an
absolute lower limit of 73 GeV/c2 is set on the mass of the lighter selectron
at the 95% confidence level. Similarly, limits on the masses of the heavier
selectron and of the sneutrino are set at 107 and 84 GeV/c2, respectively.
Additional constraints are derived from the results of the searches for Higgs
bosons. The results are also interpreted in the framework of minimal
supergravity.


title: Search for eta_b(1S) in Inclusive Radiative Decays of the Upsilon(3S)

abstract:
  We have searched for the bottomonium eta_b(1S) via the hindered magnetic
dipole (M1) photon transition Upsilon(3S) -> gamma eta_b(1S). No evidence for
such a transition is found in the data sample of 4.7 x 10^6 Upsilon(3S)'s
collected with the CLEO-III detector. We set upper limits on the branching
ratio from 9.30 to 9.43 GeV/c^2 of eta_b(1S) masses. These upper limits rule
out many previously published phenomenological estimates of the rate for this
transition.


title: A Study of Time-Dependent CP Asymmetry in B0 --> J/psi pi0 Decays

abstract:
  We present our first study of the time-dependent CP-violating asymmetry in B0
--> J/psi pi0 decays using e^+e^- annihilation data collected with the BABAR
detector at the Y(4S) resonance during the years 1999--2002 at the PEP-II
asymmetric-energy B Factory at SLAC. With about 88 million B Bbar pairs, our
preliminary results for the coefficients of the cosine and sine terms of the CP
asymmetry are C_{J/psi pi0} = 0.38 +/- 0.41 (stat) +/- 0.09 (syst) and S_{J/psi
pi0} = 0.05 +/- 0.49 (stat) +/- 0.16 (syst).


title: Measurement of Inclusive B --> psi Production

abstract:
  Using the combined CLEO II and CLEO II.V data sets of 9.1 fb^{-1} at the
Upsilon(4S), we measure properties of Psi mesons produced directly from decays
of the B meson, where ``B'' denotes an admixture of B+, B-, B0, and B0bar, and
``Psi'' denotes either J/Psi or Psi(2S). We report first measurements of Psi
polarization in B -> Psi(direct) X: alpha(J/Psi) = -0.30 {+0.07 -0.06 stat}
{+-0.04 syst} and alpha(Psi(2S)) = -0.45 {+0.22 -0.19 stat} {+-0.04 syst}. We
also report improved measurements of the momentum distributions of Psi produced
directly from B decays, correcting for measurement smearing. Finally, we report
measurements of the inclusive branching fraction for B -> Psi X and B -> Chi_c1
X.


title: First Observation of Upsilon(1D) States

abstract:
  The CLEO III experiment has recently accumulated a large statistics sample of
4.73 x 10^6 Upsilon(3S) decays. We present the first evidence for the
production of the triplet Upsilon(1D) states in the four-photon cascade,
Upslion(3S) -> gamma chi_b(2P), chi_b(2P) -> gamma Upsilon(1D), Upsilon(1D) ->
gamma chi_b(1P), chi_b(1P) -> gamma Upsilon(1S), followed by the Upsilon(1S)
annihilation to e+ e- or mu+ mu-. The signal has a significance of 9.7 standard
deviations. The measured product branching ratio for these five decays, (3.3 +-
0.6 +- 0.5) x 10^{-5}, is consistent with the theoretical estimates. We see a
6.8 standard deviation signal for a state with a mass of 10162.2 +- 1.6
MeV/c^2, consistent with the Upsilon(1D_2) assignment. We also present improved
measurements of the Upsilon(3S) -> pi0 pi0 Upsilon(1S) branching ratio and the
associated di-pion mass distribution.


title: Search for Randall-Sundrum Graviton Excitations in the CMS Experiment

abstract:
  The ability of the CMS experiment to detect massive Kaluza-Klein excitations
of gravitons, predicted by the Randall-Sundrum model, is studied. The search
reach is estimated for the channel with the graviton, produced in proton-proton
collision, decaying into a pair of electrons or muons.


title: Study of Two-Photon Transitions in CLEO-III $\Upsilon(3S)$ Data

abstract:
  We have studied two-photon transitions from Upsilon(3S) decays recorded by
the CLEO-III detector in exclusive events with two photons and either two
electrons or two muons. We obtain precision measurements of the chi_b(2P_J)
masses for J=2 and J=1. The transition rates for all three spin states of the
2P triplet are measured with improved precision which leads to a better
determination of their hadronic width ratios. We also observe rare transitions
via the chi_b(1P) states. The measured rates for these transitions allow a
determination of <1P|r|3S>, the E1 matrix element, which is more sensitive to
the structure of the bb states than the <2P|r|3S> matrix element which
dominates the radiative decays of the Upsilon(3S) state. We also present first
upper limits on the branching ratios for Upsilon(3S)-> pi0 Upsilon(2S),
Upsilon(3S) -> pi0 Upsilon(1S) and a new limit for the branching ratio for
Upsilon(3S) -> eta Upsilon(1S).


title: A Search for the Decay B0 -> pi0 pi0

abstract:
  We present a search for the decay B^0 --> pi^0 pi^0 by the BABAR experiment
at the PEP-II asymmetric-energy B-factory at SLAC. Using approximately 88
million B bar{B} pairs collected between 1999 and 2002, we place a 90%
confidence level upper limit on the branching fraction of B(B^0 --> pi^0 pi^0)
< 3.6 times 10^{-6}. This result is preliminary.


title:
Preliminary Results on |V_ub| from Inclusive Semileptonic B Decays with
  Neutrino Reconstruction

abstract:
  We present an analysis of the composition of inclusive semileptonic B meson
decays using 9.4/fb of e+ e- data taken with the CLEO detector at the
Upsilon(4S) resonance. In addition to measuring the charged lepton kinematics,
the neutrino 4-vector is inferred using the hermeticity of the detector. We
perform a maximum likelihood fit over the full three-dimensional differential
decay distribution for the fractional contributions from the B -> Xc l nu
processes with Xc = D, D*, D**, and non-resonant Xc, and the process B -> Xu l
nu. From the fit results we extract |V_ub|= (4.05 +- 0.18 +- 0.58 +- 0.25 +-
0.21 +-0.56) x 10^{-3} where the errors are statistical, detector systematics,
B -> Xc l nu model dependence, B -> Xu l nu model dependence, and theoretical
uncertainty respectively.


title:
Measurements of Branching Fractions and Direct CP Asymmetries in pi^+
  pi^0, K^+ pi^0 and K^0 pi^0 B Decays

abstract:
  We present preliminary results of the analyses of B^+ --> h^+ pi^0 (with h^+
= pi^+, K^+) and B^0 --> K^0 pi^0 decays from a sample of approximately 88
million B bar{B} pairs collected by the BABAR detector at the PEP-II
asymmetric-energy B Factory at SLAC. We measure the pi^+ pi^0 branching
fraction and we obtain B(B^+ --> pi^+ pi^0) = (5.5^{+1.0}_{-0.9} +/- 0.6) times
10^{-6} with a significance of 7.7 sigma including systematic uncertainties. We
measure the K^+ pi^0 and K^0 pi^0 branching fractions to be B(B^+ --> K^+ pi^0)
= (12.8^{+1.2}_{-1.1} +/- 1.0) times 10^{-6} and B(B^0 --> K^0 pi^0) = (10.4
+/- 1.5 +/- 0.8) times 10^{-6}. At the same time, the direct CP-violating
asymmetries are investigated and we find A_{pi^+ pi^0} = -0.03_{-0.17}^{+0.18}
+/- 0.02, A_{K^+ pi^0} = -0.09 +/- 0.09 +/- 0.01 and A_{K^0 pi^0} = 0.03 +/-
0.36 +/- 0.09, where the errors are statistical and systematic, respectively.


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

abstract:
  We present preliminary results for the measurement of the branching fraction
of the decay B+- -> chi_c0 K+- from a sample of 75 million BB pairs collected
by the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. The
chi_c0 meson is reconstructed through its two-body decays to pi+ pi- and K+ K-.
We measure BR(B+- -> chi_c0 K+-) * BR(chi_c0 -> pi+ pi-) = (1.08 +- 0.35 (stat)
+- 0.10 (syst))*10^-6 and BR(B+- -> chi_c0 K+-) * BR(chi_c0 -> K+ K-) = (1.48
+- 0.44 (stat) +- 0.17 (syst)) * 10^-6. Using the known values for the chi_c0
decays branching fractions, we combined these results to obtain BR(B+- ->
chi_c0 K+-) = (2.4 +- 0.7) * 10^-4.


title: Dalitz Analysis of D^0 --> K_S^0 pi+ pi-

abstract:
  In e^+e^- collisions using the CLEO detector we have studied the decay of the
D^0 to the final state K_S^0 pi^+ pi^- with the initial flavor of the D^0
tagged in charged D^* decay. We use the Dalitz technique to measure the
resonant substructure in this final state and clearly observe ten different
contributions by fitting for their amplitudes and relative phases. We observe a
K^{* +} pi^- component which arises from doubly Cabibbo suppressed decays or
D^0 - {D^0}-bar mixing.


title:
Search for CP Violation in B0/B0b Decays to pi+pi-pi0 and K+-pi-+pi0 in
  Regions Dominated by the rho+- Resonance

abstract:
  We present preliminary measurements of direct and indirect CP-violating
asymmetries in the decays of neutral B mesons to pi+pi-pi0 and K+-pi-+pi0 final
states dominated by the rho+- resonance, using a time-dependent maximum
likelihood analysis. The data sample comprises 88 10^ Upsilon(4S) -> BBb decays
(80.8 fb-1) collected with the BaBar detector at the PEP-II asymmetric-energy B
Factory at SLAC. For the CP violation parameters, we measure A_{CP}(rho K) =
0.19 +/- 0.14 (stat) +/- 0.11 (syst),
  A_{CP}(rho pi) = -0.22 +/- 0.08 (stat) +/- 0.07 (syst),
  C(rho pi) = 0.45 +0.18/-0.19 (stat) +/- 0.09 (syst),
  S(rho pi) = 0.16 +/- 0.25 (stat) +/- 0.07 (syst).
  For the other parameters in the description of the B0B0b -> rho pi decay-time
dependence, we obtain DeltaC(rho pi) = 0.38 +0.19/-0.20 (stat) +/- 0.11 (syst),
  DeltaS(rho pi) = 0.15 +/- 0.26 (stat) +/- 0.05 (syst).


title: A Search for B->Knunubar

abstract:
  We present a preliminary search for the flavor-changing neutral current decay
B^+ -> K^+ nunubar using 56 million Y(4S) decays recorded with the BABAR
detector at the SLAC B factory. Identification of the B^+ -> K^+ nunubar final
state, with two neutrinos, requires the reconstruction of the companion B in
the event. The companion B is reconstructed in the decay mode B^- -> D^0 l^-
nubar X, which provides both high efficiency and good purity. The particles not
used in the reconstruction of the companion B are compared with the signature
expected for B^+ -> K^+ nunubar decays. Two candidates are found in the data
with an expected background of 2.2 events. Under the assumption that all
candidates are signal events, an upper limit on the branching fraction for B^+
-> K^+ nunubar of 9.4 x 10^-5 at 90% confidence level is determined.


title: Measurement of sin2beta in B0 to Phi K0S

abstract:
  We present a preliminary measurement of the time-dependent CP-violating
asymmetry in the neutral B decay B0 --> phi K0S, with phi --> K+K- and K0S -->
pi+pi-. The measurement uses a data sample of about 87 million Y(4S) --> B Bbar
decays collected between 1999 and 2002 with the BaBar detector at the PEP-II
asymmetric-energy B Factory at SLAC. In this sample we study events in which
the CP final state is fully reconstructed and the flavor of the other neutral B
meson is determined from its decay products. The amplitude of the CP-violating
asymmetry sin2beta is derived from the decay-time distributions. We measure
sin2beta = -0.19 +0.52-0.50 (stat) +/- 0.09 (syst) (preliminary).


title:
Simultaneous Measurement of the B0 Meson Lifetime and Mixing Frequency
  with B0 --> D*- l+ nu_l Decays

abstract:
  We measure the B0 lifetime tau_B0 and the B-Bbar oscillation frequency
Deltam_d with a sample of approximately 14,000 exclusively reconstructed B0 ->
D*- l+ nu_l signal events, selected from 23 million B-Bbar pairs recorded at
the Upsilon(4S) resonance with the BABAR detector at the Stanford Linear
Accelerator Center. The b-quark flavor of the other B at the time of decay and
its decay position are determined inclusively. The lifetime and oscillation
frequency are measured simultaneously with an unbinned maximum-likelihood fit
that uses, for each event, the measured difference in B decay times (Delta-t),
the calculated uncertainty on Delta-t, the signal and background probabilities,
and b-quark tagging information for the other B. The preliminary results are
tau_B0 = (1.523 +0.024 -0.023 (stat) +/- 0.022 (syst)) ps and Deltam_d = (0.492
+/- 0.018 (stat) +/- 0.013 (syst)) ps^-1. The statistical correlation
coefficient between tau_B0 and Deltam_d is -0.22.


title:
Measurement of Time-Dependent CP Asymmetries and the CP-odd Fraction in
  the Decay B^0 --> D^{*+}D^{*-}

abstract:
  We present a measurement of time-dependent CP asymmetries and an updated
determination of the CP-odd fraction in the decay B^0 --> D^{*+}D^{*-}. The
measurements are derived from a data sample of 88 times 10^{6} B bar{B} pairs
collected by the BaBar detector at the PEP-II energy asymmetric B Factory at
SLAC. All results are preliminary.


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

abstract:
  A search for the exclusive radiative decays B->rho(770) gamma and
B^0->omega(782) gamma is performed on a sample of 84 million BB-bar events
collected by the BABAR detector at the PEP-II asymmetric e^+e^- collider. No
significant signal is seen in any of the channels. We set preliminary upper
limits of BR[B^0->rho^0 gamma]< 1.4 times 10^{-6}, BR[B^+ -> rho^+ gamma] < 2.3
times 10^{-6} and BR[B^0 -> omega gamma]< 1.2 times 10^{-6} at 90% Confidence
Level. Combining these into a single limit on the generic process B-> rho
gamma, we find the preliminary limit BR[B -> rho gamma]<1.9 times 10^{-6},
corresponding to a limit of BR[B -> rho gamma]/BR[B-> K* gamma] < 0.047 at 90%
Confidence Level.


title: b --> s gamma using a Sum of Exclusive Modes

abstract:
  This paper describes preliminary results on the inclusive process b --> s
gamma obtained from 20.7 fb^-1 of data recorded with the BaBar detector during
1999-2000. Signal event yields are found from a combination of twelve exclusive
decay channels after subtracting continuum and BBbar backgrounds. Cross-feed
from incorrectly reconstructed b --> s gamma events is also removed. Branching
fractions in bins of hadronic mass are calculated using corrected Monte Carlo
signal efficiencies; this is equivalent to measuring the gamma energy spectrum.
We measure the first moment of the gamma energy spectrum constraining the HQET
parameter LambdaBar = (0.37 +/- 0.09 (stat) +/- 0.07 (syst) +/- 0.10 (model))
GeV/c^2. A fit to the hadronic mass spectrum gives B(b --> s gamma) = (4.3 +/-
0.5 (stat) +/- 0.8 (syst) +/- 1.3 (model))x 10^-4 for the inclusive branching
fraction. We also constrain the HQET parameter lambda_1.


title: sin2phi1 with 45 Million BBbar Pairs at Belle

abstract:
  We present an improved measurement of the standard model CP violation
parameter sin2phi1 (also known as sin2beta) based on a sample of 45 x 10^6
BBbar pairs collected at the Upsilon(4S) resonance with the Belle detector at
the KEK asymmetric-energy e^+e^- collider. One neutral B meson is reconstructed
in a J/psi Ks, psi(2s) Ks, chi_c1 Ks, eta_c Ks, J/psi K*, or J/psi KL
CP-eigenstate decay channel and the flavor of accompanying B meson is
identified from its decay products. From the asymmetry in the distribution of
the time intervals between the two B meson decay points, we obtain sin2phi1 =
0.82 +/- 0.12(stat) +/- 0.05(syst).


title:
Determination of the Branching Fraction for Inclusive Decays B -> X_{s}
  gamma

abstract:
  We present a preliminary determination of the inclusive branching fraction
for the rare radiative penguin transition B -> X_{s} gamma. The measurement is
based on a data sample of 60 million BB pairs collected between 1999 and 2001
with the BaBar detector at the PEPII asymmetric-energy e+e- B Factory at SLAC.
We study events containing a high-energy photon from one B (or Bbar) decay and
a tagging primary lepton from the decay of the other B meson. By this means, we
are able to reduce a significant component of the background without
introduction of model dependent uncertainties in the event selection
efficiency. We determine the branching fraction BR(B->X_{s} gamma)=3.88
+-0.36(stat.)+-0.37(sys.) +0.43-0.23(model.)x10^{-4}, which is consistent with
Standard Model predictions and provides a constraint on possible new physics
contributions to the electromagnetic penguin amplitude in B decays.
