title: Recent Run II QCD Results from DO

abstract:
  We present recent QCD results from the D0 experiment at the Fermilab Tevatron
Collider in pp-bar collisions at sqrt(s)=1.96 TeV. Results are presented for
the inclusive jet and dijet cross sections, a measurement of dijet azimuthal
decorrelations, studies of elastic scattering, and a search for diffractively
produced Z bosons.


title: Muon-induced neutron production and detection with GEANT4 and FLUKA

abstract:
  We report on a comparison study of the Monte Carlo packages GEANT4 and FLUKA
for simulating neutron production by muons penetrating deep underground. GEANT4
is found to generate fewer neutrons at muon energies above ~100 GeV, by at most
a factor of 2 in some materials, which we attribute mainly to lower neutron
production in hadronic cascades. As a practical case study, the muon-induced
neutron background expected in a 250 kg liquid-xenon WIMP dark matter detector
was calculated and good agreement was found for the recoil event rates. The
detailed model of neutron elastic scattering in GEANT4 was also shown to
influence the nuclear recoil spectrum observed in the target, which is
presently a shortcoming of FLUKA. We conclude that both packages are suited for
this type of simulation, although further improvements are desirable in both
cases.


title: Pentaquark Search at HERMES

abstract:
  Evidence for a narrow baryon state at 1528 +- 2.6(stat) +- 2.1(syst) MeV is
presented in quasi-real photoproduction on a deuterium target through the decay
channel p,K0 to p,pi+,pi-. The statistical significance of the peak in the p,K0
invariant mass spectrum is 4 standard deviations and its extracted intrinsic
width Gamma = 17 +- 9(stat) +- 3(syst) MeV. This state may be interpreted as
the predicted S=+1 exotic Theta+ (uudd\bar{s}) pentaquark baryon.


title: Recent Results of non-accelarator-based neutrino experiments

abstract:
  Recent results of non-accelerator-based experiments, including those of
solar, atmospheric, and reactor neutrinos oscillations, neutrinoless
double-beta decays, and neutrino magnetic moments, are reviewed. Future
projects and their respective prospects are summarized.


title: First Measurement of the Branching Fraction of e^+e^- --> B0B0bar

abstract:
  We report the first measurement of the absolute branching fraction e^+e^- -->
B0B0bar at the Upsilon(4S) resonance using data collected with the BABAR
detector at the PEP-II asymmetric-energy e^+e^- storage ring. The analysis is
performed with partial reconstruction of the decay B0bar --> D^{*+}\ell^{-}
\bar{\nu}_{\ell}$, where the presence of a signal decay is determined using
only the lepton and the soft pion from the D^{*} decay. By reconstructing
events with one or two signal decays we obtain a preliminary result of e^+e^-
--> B0B0bar = 0.486 \pm 0.010(stat.) \pm 0.009(sys.)$. Our result does not
depend on branching fractions of the B0bar and the D^{*+} decay chains, on the
individual simulated reconstruction efficiencies, on the ratio of the charged
and neutral B meson lifetimes, or on the assumption of isospin symmetry.


title:
Upper limit on the eta -> pi+pi- branching ratio with the KLOE
  experiment

abstract:
  We have searched with the KLOE detector for the P and CP violating decay eta
-> pi^+pi^- in a sample of 1.55 x 10^7 eta's from the decay phi -> eta gamma of
phi mesons produced in e+e- annihilations at DAFNE. No signal is found. We
obtain the upper limit BR(eta -> pi^+pi^-) < 1.3 x 10^-5 at 90% confidence
level.


title: Study of the decay mode D^0 -> K-K+pi-pi+

abstract:
  Using data from the FOCUS (E831) experiment at Fermilab, we present a new
measurement of the branching ratio for the Cabibbo-favored decay mode $D^0 \to
K^-K^+\pi^-\pi^+$. From a sample of $2669 \pm 101$ fully reconstructed $D^0 \to
K^-K^+\pi^-\pi^+$ events, we measure $\Gamma(D^0 \to
K^-K^+\pi^-\pi^+)/\Gamma(D^0 \to K^-\pi^-\pi^+\pi^+) = 0.0295 \pm 0.0011(stat.)
\pm 0.0008(syst.)$.
  A coherent amplitude analysis has been performed to determine the resonant
substructure of this decay mode. This analysis reveals a dominant contribution
from $D^0 \to K_1^+ K-$ modes.


title: Precision measurements from the NOMAD experiment

abstract:
  The NOMAD experiment collected unprecedent neutrino data samples, matching
both the large statistics of massive calorimeters and the reconstruction
quality of bubble chambers. This paper describes the determination of the weak
mixing angle which is ongoing in NOMAD, with a target precision of $\sim 1%$.
In addition, measurements of the $\nu_{\mu}$ quasi-elastic cross-section and of
neutrino Charged Current differential cross-section on carbon are presented.


title: First results from the CERN Axion Solar Telescope (CAST)

abstract:
  Hypothetical axion-like particles with a two-photon interaction would be
produced in the Sun by the Primakoff process. In a laboratory magnetic field
(``axion helioscope'') they would be transformed into X-rays with energies of a
few keV. Using a decommissioned LHC test magnet, CAST has been running for
about 6 months during 2003. The first results from the analysis of these data
are presented here. No signal above background was observed, implying an upper
limit to the axion-photon coupling < 1.16 10^{-10} GeV^-1 at 95% CL for m_a
<~0.02 eV. This limit is comparable to the limit from stellar energy-loss
arguments and considerably more restrictive than any previous experiment in
this axion mass range.


title: High PT multi-lepton production at HERA

abstract:
  Multi-electron and multi-muon production at high transverse momentum is
measured in $ep$ scattering at HERA. Previous published analyses are extended,
combining new HERA II data taken in 2003-2004 with previous HERA I data sample.
In addition events with high $P_T$ electrons and muons are investigated here
for the first time. Yields of di-lepton and tri-lepton events are measured and
a general good agreement is found with the Standard Model prediction, dominated
by photon-photon interactions. Events are observed with leptons of high
transverse momenta in a domain where the Standard Model prediction is low.


title: B decays to open and hidden charm at Belle

abstract:
  The recent Belle collaboration measurements of B decays to open and hidden
charm are discussed. Color-suppressed decay branching fractions are measured
with an improved accuracy. The branching fractions of the $\bar{B}^0 \to D_s^+
K^-$ and $\bar{B}^0 \to D_s^- \pi^+$ decays, measured with improved accuracy,
and $\bar{B}^0 \to D_{sJ}^+ K^-$ and $\bar{B}^0 \to D_{sJ}^- \pi^+$ decays,
measured for the first time, are compared. The two-body invariant masses of the
three-body $B^0 \to D^{(*)0} \pi^+ \pi^-$ and $B^0 \to J/\Psi \pi^+ \pi^-$
decays are studied.


title: QCD'04: Recent Results from Belle

abstract:
  The huge data sample accumulated at the KEKB storage ring allows for
dedicated analyses in charm spectroscopy. A new, narrow resonance with a mass
of 3.872\GeV was found in decays of $B$ mesons. Its properties remain
unexplained. Results on various properties of the \DsJ resonances have been
updated. Older results on the unexpectedly large cross section for double
charmonium production in \epem annihilation have been confirmed and a refined
analysis is presented.


title: Searches and electroweak measurements at HERA

abstract:
  The H1 and ZEUS collaborations have used the HERA I data to search for
physics beyond the SM and to test electroweak physics in electron-proton
collisions. The new period of data taking (HERA II) has started and first HERA
II analyses become available. An overview is given of recent highlights,
including isolated lepton and multi-lepton events, tests of models of new
physics and the first systematic search for deviations in all final states with
high transverse momentum.


title:
Evidence for muon neutrino oscillation in an accelerator-based
  experiment

abstract:
  We present results for muon neutrino oscillation in the KEK to Kamioka (K2K)
long-baseline neutrino oscillation experiment. K2K uses an accelerator-produced
muon neutrino beam with a mean energy of 1.3 GeV directed at the
Super-Kamiokande detector. We observed the energy dependent disappearance of
muon neutrino, which we presume have oscillated to tau neutrino. The
probability that we would observe these results if there is no neutrino
oscillation is 0.0050% (4.0 sigma).


title: Search for Single Top Production at the Tevatron

abstract:
  Searches for the electroweak production of single top quarks have been
started at the Fermilab Tevatron proton-antiproton collider using Run II data
by both the D0 and CDF collaborations. Using a dataset of approximately
160pb^-1, neither experiment finds evidence for Single Top production and sets
95% C.L. upper limits on the production cross section. The D0 limits are 19pb
on the s-channel production, 25pb on the t-channel production, and 23pb on the
combined s+t-channel production. The CDF limits are 8.5pb on the t-channel
production and 13.7pb on the combined s+t-channel production.


title:
Structure Function Measurements and Polarised Cross Section Measurements
  from HERA

abstract:
  Recent measurements of inclusive and semi-inclusive measurements from the
HERA collaborations are presented. The measurements include neutral current
structure functions $F_2$, $F_L$ and $xF_3$; the charged current cross section
including first measurements of the dependence on electron polarisation; and
measurements of the heavy quark structure functions $F_2^{c\bar{c}}$ and
$F_2^{b\bar{b}}$.


title: Top Quark Production Cross Section at E^cm=1.96TeV

abstract:
  Preliminary results on the top pair production cross section measurements by
the D0 and CDF experiments in Run II at the Tevatron are presented. The
measurements are obtained using various final state signatures.


title: The phase of the sigma -> pi-pi amplitude in J/Psi -> omega-pi-pi

abstract:
  The phase variation of the sigma -> pi-pi amplitude is accurately determined
as a function of mass from BES II data for J/Psi -> omega-pi-pi. The
determination arises from interference with the strong b1(1235)-pi amplitude.
The observed phase variation agrees within errors with that in pi-pi elastic
scattering.


title: The Kappa in J/Psi -> K^+pi^-K^-pi^+

abstract: This paper has been withdrawn pending discussions


title: The Jupiter Electron Scattering Program at Jefferson Lab

abstract:
  JUPITER (Jlab Unified Program to Investigate nuclear Targets and
Electroproduction of Resonances) is a new collaboration between the Nuclear
Physics Electron Scattering and High Energy Physics Neutrino Scattering
  Communities to Investigate the Structure of
  Nucleons and Nuclei with Electron and Neutrino Beams.
  The first phase of JUPITER is Hall C experiment E04-001 on
  Inclusive Electron Scattering from Nuclear Targets. First data run of E04-001
is currently scheduled for January of 2005.


title: Exotic hadronic states at HERA

abstract:
  Recent results from H1, ZEUS, HERMES and HERA-B on searches for exotic
baryons in ep collisions, eD scattering and pA scattering at HERA are reviewed.
Evidence for the production of the strange pentaquark Theta^+ and of a narrow
anti-charmed baryon decaying to D^{*-}p together with negative results of
pentaquark searches at HERA are presented.


title:
Measurement of F_2^ccbar and F_2^bbbar at High Q^2 using the H1 Vertex
  Detector at HERA

abstract:
  Measurements are presented of inclusive charm and beauty cross sections in
e^+p collisions at HERA for values of photon virtuality Q^2 > 150 GeV^2 and of
inelasticity 0.1 < y < 0.7. The charm and beauty fractions are determined using
a method based on the impact parameter, in the transverse plane, of tracks to
the primary vertex, as measured by the H1 vertex detector. The data are divided
into four regions in Q^2 and Bjorken x, and values for the structure functions
F_2^{c\bar{c}} and F_2^{b\bar{b}} are obtained. The results are found to be
compatible with the predictions of perturbative quantum chromodynamics.


title:
Determination of the CKM Matrix Element |V_cb| from Semileptonic B
  Decays

abstract:
  We report studies of semileptonic decays, B --> X_c l nu, based on a sample
of 88 million BB events recorded with the BABAR detector. We have measured four
moments of the electron energy distribution and four moments of the hadronic
mass distribution, each as a function of the minimum electron energy. From
these moments we determine the inclusive branching fraction, the CKM matrix
element |V_cb|, and other heavy quark parameters, using Heavy Quark Expansions
(HQE) to order 1/m_b^3 in the kinetic mass scheme. In addition, we have studied
a large sample of exclusive B^0 --> D^*- l^+ nu decays. This sample is used to
extract the vector and axial form factors, the normalization and slope of the
HQET form factor to determine |V_cb|.


title:
Search for Doubly-charged Higgs Boson Production in the Decay H++H-- ->
  mu+mu+mu-mu- with the DO Detector at sqrt{s}=1.96} TeV

abstract:
  A search for the pair production of doubly-charged Higgs bosons in the
process $\ppbar\to\Hpp\Hmm\to \mu^+\mu^+\mu^-\mu^-$ is performed with the D\O\
Run II detector at the Fermilab Tevatron using inclusive di-muon events. These
data taken at an energy of $\sqrt{s}=1.96$ TeV correspond to an integrated
luminosity of $113 $pb$^{-1}$ and were recorded by D{\O}between August 2002 and
June 2003. In the absence of a signal, 95% Confidence Level mass limits of
$M(\HpmL)>118.6$ GeV and $M(\HpmR)>98.1$ GeV are set on the pair production
cross section for left-handed and right-handed doubly-charged Higgs bosons,
assuming 100% branching into muons and hypercharge $|Y|=2$.


title:
Measurement of phi_3 with Dalitz Plot Analysis of B->D(*)K Decay at
  Belle

abstract:
  We present a measurement of the unitarity triangle angle phi_3 using a Dalitz
plot analysis of the three-body decay of the neutral D meson from the B->D(*)K
process. Using a 253 fb-1 data sample collected by the Belle experiment, we
obtain 276 signal candidates for B->DK and 69 candidates for B->D*K, where the
neutral D meson decays into K_Spi+pi-. From a combined maximum likelihood fit
to the B->DK and B->D*K modes, we obtain
phi_3=68+14-15(stat)+-13(syst)+-11(model). The corresponding two standard
deviation interval is 22<phi_3<113.


title:
Measuring cal B(D^+ --> mu^+ nu) and the Pseudoscalar Decay Constant
  f_D^+

abstract:
  In 60 inverse-pb of data taken on the psi(3770) resonance with the CLEO-c
detector, we find 8 D+ -> mu+ nu decay candidates that are mostly signal,
containing only 1 estimated background. Using this statistically compelling
sample, we measure a value of B(D+ -> mu+ nu) = (3.5 +/- 1.4 +/- 0.6) x10^(-4),
and determine fD+=(202 +/- 41 +/-17) MeV.


title: Experimental tests of QCD at hadronic colliders

abstract: We present a general overview of recent QCD results at hadronic colliders.


title: Hadronic interaction of the eta meson with two nucleons

abstract:
  The COSY-11 collaboration has conducted experiments aiming at the
determination of the excitation function and phase-space population of the p p
--> p p eta reaction close to the kinematical threshold. The precise data
obtained with the stochastically cooled proton beam of the cooler synchrotron
COSY and the high resolution zero-degree magnetic spectrometer allowed for the
observation of the significant deviations - in the shape of the excitation
function and two-particle invariant masses - from the predictions based on the
assumption that the reaction phase space is homogenously populated. Comparison
of the shape of the excitation function for the p p --> p p eta and p p --> p p
eta-prime reaction allows to distinquish in the model independent way an
influence originating from the proton-proton and proton-eta interaction. For
the comparison the full data set from experiments performed at COSY and other
laboratories is used.


title: Neutral Higgs Boson Search at Tevatron

abstract:
  We review searches for neutral Higgs Boson performed by the CDF and D0
collaborations using approximately 200 pb$^{-1}$ of the dataset accumulated
from $p\bar p$ collisions at the center-of-mass energy of 1.96 TeV. No signals
are found and limits on the Standard Model (SM) Higgs or SM-like Higgs
production cross section times branching ratio and couplings of the Higgs boson
in MSSM are presented, including the future prospects of discovery Higgs at the
end of Run II.


title: Measurements of B meson decays to omega K* and omega rho

abstract:
  We describe searches for B meson decays to the charmless vector-vector final
states omega K* and omega rho in 89 million B-Bbar pairs produced in e+e-
annihilation at sqrt(s)=10.58 GeV. We measure the following branching fractions
in units of 10^{-6}:
  BF(B0 -> omega K*0) = 3.4 +1.8 -1.6 +/- 0.4 (<6.0),
  BF(B+ -> omega K*+) = 3.5 +2.5 -2.0 +/- 0.7 (<7.4),
  BF(B0 -> omega rho0) = 0.6 +1.3 -1.1 +/- 0.4 (<3.3), and BF(B+ -> omega rho+)
= 12.6 +3.7 -3.3 +/- 1.6. The first error quoted is statistical, the second
systematic, and the upper limits are defined at 90% confidence level. For B+ ->
omega rho+ we also measure the longitudinal spin alignment fraction f_L = 0.88
+0.12 -0.15 +/- 0.03 and charge asymmetry Ach = (5 +/- 26 +/- 2)%.


title: Recent $J/\psi$ Results from BESII

abstract:
  The studies on the multi-quark candidates, light scalar mesons and excited
baryon states at BES are presented, based on $5.8 \times 10^7$ $J/\psi$ data
collected with BESII detector. The measurements of some $J/\psi$ and $\eta_c$
decays are presented too. We also report the searches for the lepton flavor
violation and pentaquark states in $J/\psi$ decays.


title:
New Measurements of Time-Dependent CP-Violating Asymmetries in B0 ->
  KsKsKs and Ks pi0 gamma Decays at Belle

abstract:
  We present new measurements of CP-violation parameters in B0 -> KsKsKs and Ks
pi0 gamma decays based on a sample of 275 x 10^6 BBbar pairs collected at the
Upsilon(4S) resonance with the Belle detector at the KEKB energy-asymmetric
e+e- collider. One neutral B meson is fully reconstructed in one of the
specified decay channels, and the flavor of the accompanying B meson is
identified from its decay products. CP-violation parameters are obtained from
the asymmetries in the distributions of the proper-time intervals between the
two B decays. We obtain S_{KsKsKs} = +1.26 +/- 0.68(stat) +/- 0.18(syst),
A_{KsKsKs} = +0.54 +/- 0.34(stat) +/- 0.08(syst), S_{Ks pi0 gamma} = -0.58
+0.46/-0.38(stat) +/- 0.11(syst), A_{Ks pi0 gamma} = +0.03 +/- 0.34(stat) +/-
0.11(syst). All results are preliminary.


title:
Marked influence of the nature of chemical bond on CP-violating
  signature in molecular ions $\mathrm{HBr}^{+}$ and $\mathrm{HI}^{+}$

abstract:
  Heavy polar molecules offer a great sensitivity to the electron Electric
Dipole Moment(EDM). To guide emerging searches for EDMs with molecular ions, we
estimate the EDM-induced energy corrections for hydrogen halide ions
$\mathrm{HBr}^{+}$ and $\mathrm{HI}^{+}$ in their respective ground $X
^2\Pi_{3/2}$ states. We find that the energy corrections due to EDM for the two
ions differ by an unexpectedly large factor of fifteen. We demonstrate that a
major part of this enhancement is due to a dissimilarity in the nature of the
chemical bond for the two ions: the bond that is nearly of ionic character in
$\mathrm{HBr}^{+}$ exhibits predominantly covalent nature in $\mathrm{HI}^{+}$.
We conclude that because of this enhancement the HI$^+$ ion may be a
potentially competitive candidate for the EDM search.

title: CP Violation in b->s Decays and New Physics Phases

abstract:
  We present new measurements of CP-violation parameters in B0->phi/Ks, K+K-Ks,
f0(980)Ks, eta'Ks, omega/Ks, Pi0/Ks, and K*0(KsPi0)/gamma decays based on a
sample of 275x10^6 BBbar pairs collected at the Y(4S) resonance with the Belle
detector at the KEKB energy-asymmetric e+e- collider. One neutral B meson is
fully reconstructed in one of the specified decay channels, and the flavor of
the accompanying B meson is identified from its decay products. CP-violation
parameters for each of the decay modes are obtained from the asymmetries in the
distributions of the proper-time intervals between the two B decays. All
results are preliminary.


title:
Measurement of the Forward-Backward Charge Asymmetry of
  Electron-Positron Pairs in Proton anti-Proton Collisions at s**(1/2)=1.96-TeV

abstract:
  We present a measurement of the mass dependence of the forward-backward
charge asymmetry (A_{FB}) for electron-positron pairs produced via an
intermediate Z/gamma with mass Mee > 40 GeV/c**(2). We study the constraints on
the Z-quark couplings imposed by our measurement. We analyze an integrated
luminosity of 72 pb-1 collected by the CDF II detector in proton anti-proton
collisions at s**(1/2) = 1.96 TeV at the Fermilab Tevatron. A comparison of the
uncorrected A_{FB} between data and Standard Model Monte Carlo gives good
agreement with a chi^2/DOF of 15.7/15. The couplings measurements are also
consistent with Standard Model predictions.


title:
Au+Au Collisions at RHIC and implications for ultra-relativistic
  astrophysical A+A collisions

abstract:
  Results from ultra-relativistic Au+Au collisions at RHIC are reviewed.
Emphasis is put upon (a) measured properties of a Au+Au collision, which might
be used as input to cosmic air shower Monte-Carlo event generators, (b)
production of anti-matter, and (c) forward physics.


title: A search for the decay $B^+ \to K^+ \nu \bar{\nu}$

abstract:
  We search for the rare flavor-changing neutral-current decay $B^+ \to K^+ \nu
\bar{\nu}$ in a data sample of 82 fb$^{-1}$ collected with the {\sl BABAR}
detector at the PEP-II B-factory. Signal events are selected by examining the
properties of the system recoiling against either a reconstructed hadronic or
semileptonic charged-B decay. Using these two independent samples we obtain a
combined limit of ${\mathcal B}(B^+ \to K^+ \nu \bar{\nu})<5.2 \times 10^{-5}$
at the 90% confidence level. In addition, by selecting for pions rather than
kaons, we obtain a limit of ${\mathcal B}(B^+ \to \pi^+ \nu \bar{\nu})<1.0
\times 10^{-4}$ using only the hadronic B reconstruction method.


title:
The \theta_{13} and \delta_{CP} sensitivities of the SPL-Frejus project
  revisited

abstract:
  An optimization of the CERN SPL beam line has been performed guided by the
sensitivities to the \theta_{13} mixing angle and to the \delta_{CP} Dirac CP
violating phase. A UNO-like 440 ktons water Cerenkov detector located at 130 km
from the target in a new foreseen Frejus laboratory has been used as a generic
detector. Concerning the \delta_{CP} independent \theta_{13} sensitivity, a
gain of about 20% may be reached using a 3.5 GeV proton beam with a 40 m long,
2 m radius decay tunnel compared to the up to now considered 2.2 GeV beam
energy and 20 m long, 1 m radius decay tunnel. This may motivate new machine
developments to upgrade the nominal SPL proton beam energy.


title: Searches for Higgs Bosons and Supersymmetry at the Tevatron

abstract:
  With almost 0.5fb-1 of ppbar-collisions delivered in Tevatron Run II, both
experiments CDF and D0 are reporting first results from a vast number of search
analyses. This article summarizes the current status of Tevatron searches for
Higgs bosons within the Standard Model and its extensions as well as direct
searches for supersymmetric particles. Signatures for production of squarks,
gluinos, charginos and neutralinos as predicted by gravity- and gauge-mediated
SUSY breaking scenarios have been considered. No evidence for Higgs bosons or
SUSY particles has been found so far. New limits are derived which
significantly improve on existing limits.


title: Open strangeness threshold production at COSY-11

abstract:
  The open strangeness production near threshold is investigated at the
internal experiment COSY-11 in different reaction channels. Recently, the main
focus has been to extend measurements of the hyperon production
pp->pK+Lambda/Sigma0 in different isospin channels as well as the associated
strangeness production in pp->ppK+K-. The experimental technique is based on
the reconstruction of the four momentum for all positively charged ejectiles.
Neutrons are detected in addition using a neutral particle detector. The
unregistered hyperon or meson is identified by means of the missing mass
technique. The present status of the analysis for both reaction channels is
presented. In case of the reaction pp->ppK+K-, very preliminary cross sections
are shown.


title: Observation of B+ -> K+ eta gamma

abstract:
  We report measurements of radiative B decays with K eta gamma final states,
using a data sample of 253 /fb recorded at the Upsilon(4S) resonance with the
Belle detector at the KEKB e+e- storage ring. We observe B+ -> K+ eta gamma for
the first time with a branching fraction of (8.4 +- 1.5(stat) +1.2 -0.9(syst))
X 10^{-6} for M(Keta) < 2.4 GeV/c^2, and find evidence of B0 -> K0 eta gamma.
We also search for B -> K3*(1780) gamma.


title:
Spectra of prompt electrons from decays of B+ and B0 mesons and ratio of
  inclusive semielectronic branching fractions

abstract:
  We present spectra of prompt electrons from decays of neutral and charged B
mesons. The results are based on 140 /fb of data collected by the Belle
detector on the Upsilon(4S) resonance at the KEKB e+e- asymmetric collider. We
tag Upsilon(4S) -> B \bar{B} events by reconstructing a B meson in one of
several hadronic decay modes; the semileptonic decay of the other B meson is
inferred from the presence of an identified electron. We obtain for charged and
neutral B mesons the partial rates of semileptonic decay, to electrons with
momentum greater than 0.6 GeV/c in the B rest frame, and their ratio b_+/b_0 =
1.08 +- 0.05 +- 0.02, where the first and second errors are statistical and
systematic, respectively.


title: Searches for Extra Dimensions at the Tevatron

abstract:
  Models in which gravity and/or Standard Model gauge bosons propagate in more
than three spatial dimensions have implications that can be tested at current
colliders. In this paper, we report on the results from searches for extra
dimensions at the two Tevatron experiments, CDF and D0, which utilize up to 200
pb^-1 of proton-antiproton collision data from Run II taken at 1.96 TeV CoM
energy, between spring 2002 and fall 2003.


title: Photon transitions in Upsilon(2S) and Upsilon(3S)

abstract:
  We have studied the inclusive photon spectra in Upsilon(2S) and \Upsilon(3S)
decays using a large statistics data sample obtained with the CLEO III
detector. We present the most precise measurements of electric dipole (E1)
photon transition rates and photon energies for Upsilon(2S)->gamma chi_bJ(1P)
and Upsilon(3S)->gamma chi_bJ(2P) J=0,1,2. We measure the rate for a rare E1
transition Upsilon(3S)->gamma chi_b0(1P) for the first time. We also set upper
limits on the rates for the hindered magnetic dipole (M1) transitions to the
eta_b(1S) and eta_b(2S) states.


title: Measurement of the Radiative Ke3 Branching Ratio

abstract:
  We present a measurement of the relative branching ratio of the decay KL ->
pi e nu gamma (Ke3gamma) with respect to KL-> pi e nu (gamma) (Ke3+Ke3gamma)
decay. The result is based on observation of 19 000 Ke3gamma and 5.6 x 10^6 Ke3
decays. The value of the branching ratio is Br(Ke3gamma, Egamma^*>30
MeV,theta(e,gamma)^*>20^o)/Br(Ke3)= (0.964+-0.008+0.011-0.009)%. This result
agrees with theoretical predictions but is at variance with a recently
published result.


title:
Measurement of the W Boson Polarization in Top Decay at CDF at s**(1/2)
  = 1.8 TeV

abstract:
  The polarization of the $W$ boson in $t \to W b$ decay is unambiguously
predicted by the Standard Model of weak interactions and is a powerful test of
our understanding of the $tbW$ vertex. The subsequent $W \to l \nu$ decay
serves as a polarimeter for the $W$, and the invariant mass of the lepton and
$b$ quark in top decay provides a measurement of the $W$ decay angle. In this
paper we present a measurement of the decay rate of the W produced from the
decay of the top quark in the hypothesis of V+A structure of the tWb vertex. We
find no evidence for the non-standard V+A vertex and set a limit on $f_{V+A}$
$<$ 0.80 @ 95% confidence level. By combining this result with a complementary
observable in the same data, we assign a limit of $f_{V+A}$ $<$ 0.61 @ 95% CL.


title: New Physics Searches at LEP

abstract:
  A short summary is made of several searches for new physics performed at the
highest LEP2 energies.


title: Searches for Supersymmetry at the Tevatron

abstract:
  Both Tevatron experiments, D0 and CDF, have searched for signs of
Supersymmetry in the present Run II data sample, using integrated luminosities
of up to 260/pb collected in ppbar collisions at a center-of-mass energy of
1.96TeV. In these proceedings, new results are presented in the search for
squarks and gluinos in the jets and missing transverse energy final state,
associated production of charginos and neutralinos with multilepton final
states, search for the rare decay B_s->mumu, searches allowing R-parity
violation (muons+jets, multileptons), and searches in the gauge mediated
supersymmetry breaking framework with the final state of two photons and
missing transverse energy. In the absence of any significant deviation from
Standard Model expectations, limits on the presence of new physics are set,
which in many cases are the most stringent to date.

abstract:
  Based on a sample of 5.8X 10^7 J/psi events taken with the BESII detector,
the branching fractions of J/psi--> 2(pi+pi-)eta and J/psi-->3(pi+pi-)eta are

Charge Fluctuations in $\pi^{+}\rp$ and $\rK^{+}\rp$ Collisions at 250
  GeV/$c$

abstract:
  We report on measurements of event-by-event charge fluctuations in
$\pi^{+}\rp$ and $\rK^{+}\rp$ collisions at 250 GeV/$c$. The dependence of
these fluctuations on the size of the rapidity windows are presented for the
first time in the full phase space domain. The corrections for the influence of
global charge conservation and leading-particle stopping are tested by the
data. The discrepancy due to incomplete correction given by STAR and PHENIX are
estimated. The dependence of the fluctuations on the position of the rapidity
bin and on the multiplicity at different rapidity windows are also presented.


title: Constraints upon the CKM angle phi_2 (alpha) from Belle

abstract:
  The Belle experiment has measured branching fractions and CP asymmetries for
the charmless decays B0->pi+pi- and B0->rho+-pi-+. From these measurements,
constraints upon the CKM angle phi_2 can be obtained. These constraints
indicate that phi_2 is around 100 degrees.


title: Spin Physics at Compass

abstract:
  COMPASS is a new fixed target experiment presently in operation at CERN. It
has the goal to investigate hadron structure and hadron spectroscopy by using
either muon or hadron beams. From measurements of various hadron asymmetries in
polarized muon - nucleon scattering it will be possible to determine the
contribution of the gluons to the nucleon spin. Main objective of the hadron
program is the search of exotic states, and glueballs in particular. This
physics programme is carried out with a two-stage magnetic spectrometer, with
particle identification and calorimetry in both stages, which has started
collecting physics data in 2002, and will run at the CERN SPS at least until
2010. Preliminary results from the 2002 run with a 160 GeV muon beam are
presented for several physics channels under investigation.


title: A new path toward gravity experiments with anti-hydrogen

abstract:
  We propose to use a 13 KeV antiproton beam passing through a dense cloud of
positronium (Ps) atoms to produce an H+ beam. These ions can be slowed down and
captured by a trap. The process involves two reactions with large cross
sections under the same experimental conditions. These reactions are the
interaction of p with PS to produce H and the e+ capture by H reacting on PS to
produce H+. Once decelerated with an electrostatic field and captured in a trap
the H+ ions could be cooled and the e+ removed with a laser to perform a
measurement of the gravitational acceleration of neutral antimatter in the
gravity field of the Earth.


title: Search for $e^+e^- --> Lambda_b^0 barLambda_b^0 Near Threshold

abstract:
  Using the CLEO III detector at CESR we study e+e- collisions in the
center-of-mass energy close to, or above, Lambda_b anti-Lambda_b production
threshold. We search for evidence of Lambda_b anti-Lambda_b resonance
production and set upper limits based on inclusive hadron production as a
barometer of Lambda_b anti-Lambda_b production.

Branching Fractions and CP Asymmetries in Two-Body Nonleptonic Charmless
  b-Hadron Decays

abstract:
  Relative branching fractions of B^0_d,s -> h^+ h^'- decays (where h, h' = K
or pi) and the direct CP asymmetry A_CP in the B^0_d -> K^+ pi^- mode are
measured with 179 +- 11 pb^-1 of data collected at sqrt{s} = 1.96 TeV using the
CDF II detector at the Fermilab Tevatron ppbar collider. The first
branching-fraction measurement of a B^0_s meson to two pseudoscalars, Br(B^0_s
-> K^+ K^-), and a search for the baryon mode Lambda^0_b -> p^+ h^- are also
presented, in addition to branching-fraction limits on the rare channels B^0_s
-> K^+ pi^-, B^0_d -> K^+ K^-, and B^0_s -> pi^+ pi^-.


title: Searches for new Physics at HERA

abstract:
  Results of a general search for new phenomena at high transverse momentum and
of a dedicated search for events with isolated leptons and missing transverse
momentum are reported. These searches were performed on a data sample collected
at HERA in e+-p collisions with the H1 detector in the period 1994-2004. The
results obtained in the isolated lepton search are compared with those obtained
by the ZEUS collaboration in the period 1994-2000 and limits on the anomalous
FCNC production of single top events are presented.


title: KLOE results at the Frascati $\phi$-factory DA$\Phi$NE

abstract:
  The KLOE experiment at the Frascati $\phi$-factory DA$\Phi$NE has collected
about 0.5 fb$^{-1}$ of data till the end of the year 2002. These data allow to
perform a wide physics program, ranging from the physics of charged and neutral
kaons to radiative $\phi$-decays. Results are presented for the $K_L$ lifetime
and the semileptonic processes $K_{S,L} \to \pi e \nu$. From the light meson
spectroscopy program, results on the decays $\phi \to f_0(980)\gamma,
a_0(980)\gamma$ as well as $\phi \to \eta \gamma, \eta' \gamma$ are presented.


title:
Measurement of the leptonic decay widths of the phi-meson with the KLOE
  detector

abstract:
  The phi-meson leptonic widths, Gee and Gmm, are obtained, respectively, from
the e+e- forward-backward asymmetry and the muon cross section around the
phi-mass energy. We find Gee=1.32⊕0.05⊕0.03 kev and sqrt(GeeGmm)=
1.320⊕0.018⊕0.017 kev. These results, compatible with Gee=Gmm,
provide a precise test of lepton universality. Combining the two results gives
G_lept=1.320⊕0.023 kev.


title: Chasing $\theta_{13}$ with new reactor neutrino experiments

abstract:
  It is now widely accepted that a new middle baseline disappearance reactor
neutrino experiment with multiple detectors could provide a clean measurement
of the $\theta_{13}$ mixing angle, free from any parameter degeneracies and
correlations induced by matter effect and the unknown leptonic Dirac CP phase.
The current best constraint on the third mixing angle comes from the Chooz
reactor neutrino experiment $\sin^{2}(2\theta_{13})<0.2$ (90$ %$ C.L., $\Delta
m_{\rm atm}^{2}=2.0 10^{-3}$ eV$^{2}$). Several projects of experiment, with
different timescales, have been proposed over the last two years all around the
world. Their sensitivities range from $\sin^{2}(2\theta_{13})<$ 0.01 to 0.03,
having thus an excellent discovery potential of the $\nu_e$ fraction of
$\nu_3$.


title:
A Search for Anomalous Heavy-Flavor Quark Production in Association with
  W Bosons

abstract:
  We present a search for anomalous production of heavy-flavor quark jets in
association with a W boson at the Fermilab Tevatron ppbar Collider. This search
is conducted through an examination of the exclusive jet spectrum of W+jets
final states in which the heavy-flavor quark content has been enhanced by
requiring at least one tagged jet in an event. Jets are tagged by the combined
use of two algorithms, one based on semileptonic decays of b/c hadrons, and the
other on their lifetimes. We compare data in e+jets (164 pb-1) and mu+jets (145
pb-1) channels, collected with the D0 detector at sqrt{s}=1.96 TeV, to
expectations from the standard model, and set upper limits on anomalous
production of such events.


title: Searches for exotica at LEP

abstract:
  The results of various searches for new physical phenomena beyond the
Standard Model using data from the four LEP experiments are summarized. Topics
presented include the search for flavour-changing neutral currents with single
top production, compositeness leading to the production of excited leptons, and
manifestations of extra dimensions.


title: Review of Recent BaBar Results

abstract:
  We present a review of recent results from BaBar experiment. BaBar detector
has collected about 256 millions of $B\bar B$ events at PEP-II, the asymmetric
$e^+e^-$ collider located at SLAC running at the $\Upsilon(4S)$ resonance. We
have studied CP violation in B mesons, observing the first evidence of direct
CP violation in B meson decays and measured CP asymmetries relevant for the
determination of the angles of the CKM Unitarity Triangle. BaBar physics
program covers many other topics, including measurements of CKM matrix
elements, charm physics, and search for new physics processes.

HERMES Precision Results on g1p, g1d and g1n and the First Measurement
  of the Tensor Structure Function b1d

abstract:
  Final HERMES results on the proton, deuteron and neutron structure function
g1 are presented in the kinematic range 0.0021<x<0.9 and 0.1<Q2<20 GeV2. These
results base on a refined analysis and are corrected for radiative and detector
smearing effects using an unfolding algorithm. Furthermore, preliminary results
on the first measurement of the tensor asymmetry Azz and the tensor structure
function b1d are presented.


title: Kaons and Hyperons rare decays by the NA48 experiment at CERN

abstract:
  Some Kaons and Hyperons rare decays branching ratios and form factors were
measured by the NA48 experiment at CERN. The details of the measurements and
their importance for the understanding of the CKM quark mixing matrix are
discussed.


title: Measurements of B- -> D(*)0 K(*)- Decays Related to gamma

abstract:
  We present measurements of branching fractions and CP asymmetries of several
B- -> D(*)0 K(*)- decays, with the D(*)0 decaying to CP-even, CP-odd, and
flavor eigenstates, that can constrain the CP angle gamma as well as the
amplitude ratio rb=A(B -> u)/A(B -> c), using methods proposed by Gronau,
London and Wyler or Atwood, Dunietz and Sony. We use data collected with the
BABAR detector at the PEP-II asymmetric energy e+e- collider at SLAC.


title: Measurements of sin2alpha/phi2 from B -> pipi, rhopi and rhorho modes

abstract:
  B meson decays involving b -> u transitions are sensitive to the unitarity
triangle angle alpha (or phi2). The BaBar and Belle experiments have studied
B-meson decays to pipi, rhopi and rhorho final states. It is possible to
combine these measurements to constrain alpha with a precision of O(10 degrees)
and a central value of approximately 100 degrees. These results are consistent
with Standard Model expectations.


title:
Measurement of the Ratio BR(B- --> D*0 K-)/BR(B- --> D*0 pi-) and of the
  CP Asymmetry of B- --> D*0(CP+) K- Decays

abstract:
  We study the decays B- --> D*0 pi- and B- --> D*0 K-, where the D*0 decays
into D0 pi0, with the D0 reconstructed in the CP-even (CP+) eigenstates K- K+
and pi- pi+ and in the (non-CP) channels K- pi+, K- pi+ pi+ pi-, and K- pi+
pi0. Using a sample of about 123 million BBbar pairs, we measure the ratios of
decay rates R*(non-CP)=BR(B- --> D*0(non-CP) K-)/BR(B- --> D*0(non-CP) pi-) =
0.0813+-0.0040(stat)+0.0042-0.0031}(syst), and provide the first measurements
of R*(CP+)= BR(B- --> D*0(CP+) K-)/BR(B- --> D*0(CP+) pi-) =
0.086+-0.021(stat)+-0. 007(syst), and of the CP asymmetry A*(CP+) = (BR(B- -->
D*0(CP+) K-) - BR(B+ --> D*0(CP+) K+))/(BR(B- --> D*0(CP+) K-) + BR(B+ -->
D*0(CP+) K+)) = -0.10+-0.23(stat)+0.03-0.04(syst).


title: Hot Topics from Belle

abstract:
  The most precise current determination of the Unitarity Triangle angle
$\phi_3$ is presented. It is obtained using the decay $B^+ \to D^{(*)} K^+$,
with Dalitz plot analysis of the subsequent $D \to K_S \pi^+\pi^-$ decay. The
result is $\phi_3 = 68^\circ ^{+14^\circ}_{-15^\circ} \stat \pm 13^\circ \syst
\pm 11^\circ \model$.


title: Search for Lepton Flavour Violation in the Decay tau -> mu gamma

abstract:
  A search for the lepton flavour violating decay tau -> mu gamma has been
performed using 221.4/fb of data collected at an e+e- centre-of-mass energy of
10.58 GeV with the BABAR detector at the PEP-II storage ring. The search has an
efficiency of (7.45+/-0.65)% for an expected background level of 6.2+/-0.5
events. In the final sample 4 candidate events are selected. As there is no
evidence for a signal in this data, for this preliminary result we set an upper
limit of BR(tau -> mu gamma) < 9 x 10^-8 at 90%CL using the method of Feldman
and Cousins.

plot analysis, semileptonic form factor ratios and excited meson spectroscopy.


title:
Determination of A_{FB}^b at the Z pole using inclusive charge
  reconstruction and lifetime tagging

abstract:
  A novel high precision method measures the b-quark forward-backward asymmetry
at the Z pole on a sample of 3,560,890 hadronic events collected with the
DELPHI detector in 1992 to 2000. An enhanced impact parameter tag provides a
high purity b sample. For event hemispheres with a reconstructed secondary
vertex the charge of the corresponding quark or anti-quark is determined using
a neural network which combines in an optimal way the full available charge
information from the vertex charge, the jet charge and from identified leptons
and hadrons. The probability of correctly identifying b-quarks and anti-quarks
is measured on the data themselves comparing the rates of double hemisphere
tagged like-sign and unlike-sign events. The b-quark forward-backward asymmetry
is determined from the differential asymmetry, taking small corrections due to
hemisphere correlations and background contributions into account. The results
for different centre-of-mass energies are:
  A_{FB}^b (89.449 GeV) = 0.0637 \pm 0.0143(stat.) \pm 0.0017(syst.)
  A_{FB}^b (91.231 GeV) = 0.0958 \pm 0.0032(stat.) \pm 0.0014(syst.)
  A_{FB}^b (92.990 GeV) = 0.1041 \pm 0.0115(stat.) \pm 0.0024(syst.)
  Combining these results yields the b-quark pole asymmetry A_{FB}^{b,0} =
0.0972 \pm 0.0030(stat.) \pm 0.0014(syst.)


title:
Neutral and charged current cross section measurements and searches for
  new physics at HERA

abstract:
  HERA is the only high energy electron-proton collider in the world today and
hence has unique opportunities both to probe the structure of the proton and to
search for physics beyond the Standard Model. Results are presented for
measurements of both neutral and charged current cross sections, and for
searches for exotic processes involving direct electron-quark interactions
(leptoquarks and R-parity violating SUSY), generic coupling models (contact
interactions) and exclusive final states (isolated leptons and missing PT,
single top production and pentaquarks). Exclusion limits on proposed models are
set where no deviation from Standard Model predictions are found.


title:
Measurements of Bottom Anti-Bottom Azimuthal Production Correlations in
  Proton-Antiproton Collisions at s**(1/2)= 1.8 TeV

abstract:
  We have measured the azimuthal angular correlation of bottom anti-bottom
production, using 86.5 pb-1 of data collected by Collider Detector at Fermilab
(CDF) in proton anti-proton collisions at sqrt{s}=1.8 TeV during 1994-1995. In
high-energy p-pbar collisions, such as at the Tevatron, bottom anti-bottom
production can be schematically categorized into three mechanisms. The
leading-order (LO) process is ``flavor creation,'' where both the bottom and
anti-bottom quarks substantially participate in the hard scattering and result
in a distinct back-to-back signal in final state. The ``flavor excitation'' and
the ``gluon splitting'' processes, which appear at next-leading-order (NLO),
are known to make a comparable contribution to total bottom anti-bottom cross
section, while providing very different opening angle distributions from the LO
process. An azimuthal opening angle between bottom and anti-bottom, Delta phi,
has been used for the correlation measurement to probe the interaction creating
bottom anti-bottom pairs. The Delta phi distribution has been obtained from two
different methods. One method measures the Delta phi between bottom hadrons
using events with two reconstructed secondary vertex tags. The other method
uses b-bbar --> (J/psi X)(l X') events, where the charged lepton (l) is an
electron or a muon, to measure Delta phi between bottom quarks. The bottom
anti-bottom purity is determined as a function of Delta phi by fitting the
decay length of the J/psi and the impact parameter of the lepton. Both methods
quantify the contribution from higher-order production mechanisms by the
fraction of the b-bbar pairs produced in the same azimuthal hemisphere,
f_toward. The measured f_toward values are consistent with both parton shower
Monte Carlo and NLO QCD predictions.


title:
Measurement of the angular distribution in $\bar p p\to \psi(2S)\to
  e^+e^-$

abstract:
  We present the first measurement of the angular distribution for the
exclusive process $\bar p p \to \psi(2S)\to e^+e^-$ based on a sample of 6844
events collected by the Fermilab E835 experiment. We find that the angular
distribution is well described by the expected functional form
$\frac{dN}{d\cos\theta^{*}}$ $\propto$ 1 + $\lambda \cos^{2}\theta^{*}$, where
$\theta^{*}$ is the angle between the antiproton and the electron in the center
of mass frame, with $\lambda$ = 0.67 $\pm$ 0.15 (stat.) $\pm$ 0.04 (sys.) The
measured value for $\lambda$ implies a small but non zero $\psi(2S)$ helicity 0
formation amplitude in $\bar p p$, comparable to what is observed in $J/\psi$
decays to baryon pairs.


title: Measuring Charged-Current Muon Neutrino Interactions in MiniBooNE

abstract:
  MiniBooNE seeks to confirm or refute the LSND muon-antineutrino to
electron-antineutrino oscillation signal with high statistical significance and
different systematics. MiniBooNE has accumulated the world's largest GeV
neutrino data set. MiniBooNE employs a cosmic muon calibration system to study
the reconstruction of the energies and directions of muons in the detector.
Progress of measurements of the muon neutrino charged-current quasi-elastic and
single pion production cross sections are presented.


title: Status of the RHIC Spin Program

abstract:
  The Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory
has been developing the capability of accelerating, storing and colliding
high-energy polarized proton beams over the past several years. During this
development phase, important first measurements of cross sections and spin
asymmetries for neutral pions produced in polarized proton collisions at
$\sqrt{s}$=200 GeV have been completed by STAR and PHENIX, the two large
collider experiments at RHIC. This contribution reports on progress of the RHIC
spin program and provides an outlook for the future.


title: A Planned Jefferson Lab Experiment on Spin-Flavor Decomposition

abstract:
  Experiment E04-113 at Jefferson Lab Hall C plans to measure the beam-target
double-spin asymmetries in semi-inclusive deep-inelastic $\vec p(e, e^\prime
h)X$ and $\vec d(e, e^\prime h)X$ reactions ($h=\pi^+, \pi^-, K^+$ or$K^-$)
with a 6 GeV polarized electron beam and longitudinally polarized NH$_3$ and
LiD targets. The high statistic data will allow a spin-flavor decomposition in
the region of $x=0.12 \sim 0.41$ at $Q^2=1.21\sim 3.14$ GeV$^2$. Especially,
leading-order and next-to-leading order spin-flavor decomposition of $\Delta
u_v$, $\Delta d_v$ and $\Delta \bar{u} - \Delta \bar{d}$ will be extracted
based on the measurement of the combined asymmetries $A_{1N}^{\pi^+ - \pi^-}$.
The possible flavor asymmetry of the polarized sea will be addressed in this
experiment.


title:
Mulit-Photon Events with Large Missing energy in e+e- collisions at
  sqrt(s)=192-209 GeV

abstract:
  Events with a final state consisting of two or more photons and large missing
transverse energy have been observed in e+e- collisions at centre-of-mass
energies in the range 192 - 209 GeV using the OPAL detector at LEP.
Cross-section measurements are performed within the kinematic acceptance of the
selection and compared with the expectation from the Standard Model process
e+e- -> nu nu gamma gamma(gamma). No evidence for new physics contributions to
this final state is observed. Upper limits on sigma (e+e- -> XX) BR^2(X ->
Ygamma) are derived for the case of stable and invisible Y. In the case of
massive Y the combined limits obtained from all the data range from 10 fb to 60
fb, while for the special case of massless Y the range is 20 fb to 40 fb. The
limits apply to pair production of excited neutrions (X=nu^*,Y=nu), to
neutralino production (X=~chi^0_2, Y=~chi^0_1) and to supersymmetric models in
which X=~chi^0_1 and Y=~G is a light gravitino.


title:
Search for neutrinoless double beta decay with the NEMO-3 detector:
  first results

abstract:
  The NEMO-3 detector, which has been operating in the Frejus Underground
Laboratory since February 2003, is devoted to searching for neutrinoless double
beta decay (\beta\beta 0 \nu). The expected performance of the detector has
been successfully achieved. Half-lives of the two neutrinos double beta decay
(\beta\beta 2 \nu$) have been measured for ^{100} Mo, ^{82}Se, ^{96}Zr,
^{116}Cd and ^{150}Nd. After 265 days of data collection from February 2003
until March 2004, no evidence for neutrinoless double beta decay (\beta\beta 0
\nu) was found from \sim 7 kg of ^{100} Mo and \sim 1 kg of ^{82} Se. The
corresponding lower limits for the half-lives are 3.5 \times 10^{23} years at
90% C.L for ^{100} Mo and 1.9 \times 10^{23} years for ^{82}Se. Limits for the
effective Majorana neutrino mass are < \hspace{-0.5mm} m_{\nu} \hspace{-0.5mm}
> < 0.7-1.2 eV for ^{100} Mo and \linebreak < \hspace{-0.5mm} m_{\nu
\hspace{-0.5mm} > < 1.3-3.2 eV for ^{82}Se. Radon is the dominant background
today and a Radon-free purification system will be in operation by the end of
september 2004. The NEMO-3 expected sensitivity after 5 years of data is 0.2
eV.


title: Searching for SUSY at the Tevatron

abstract:
  An overview of recent experimental searches for SUSY particles is presented.
These searches are based on data collected by the CDF and the \D0 experiments
operating at the Fermilab Tevatron proton-antiproton collider with $\sqrt{s}$ =
1.96 TeV. The review focuses on searches for squarks and gluinos in final
states with missing transverse energy and jets. Emphasis will be given to the
search for the gluino decaying into a sbottom and $b$ quark with each sbottom
decaying into a $b$ quark and a neutralino. This scenario yields events
containing 4 $b$-jets and missing transverse energy.

A Combination of Preliminary Electroweak Measurements and Constraints on
  the Standard Model

abstract:
  This note presents a combination of published and preliminary electroweak
results from the four LEP collaborations and the SLD collaboration which were
prepared for the 2004 summer conferences. [...] The main changes with respect
to the experimental results presented in summer 2003 are updates to the W
branching fractions and four-fermion cross sections measured at LEP-2, and the
SLD/LEP heavy-flavour results measured at the Z pole. The results are compared
with precise electroweak measurements from other experiments, notably the final
result on the electroweak mixing angle determined in neutrino-nucleon
scattering by the NuTeV collaboration, the latest result in atomic parity
violation in Caesium, and the measurement of the electroweak mixing angle in
Moller scattering. The parameters of the Standard Model are evaluated, first
using the combined LEP electroweak measurements, and then using the full set of
high-$Q^2$ electroweak results.

Report of the Solar and Atmospheric Neutrino Experiments Working Group
  of the APS Multidivisional Neutrino Study

abstract:
  Both the first evidence and the first discoveries of neutrino flavor
transformation have come from experiments which use neutrino beams provided by
Nature. These discoveries were remarkable not only because they were
unexpected--they were discoveries in the purest sense--but that they were made
initially by experiments whose primary goals were aimed at other physics.
Future solar and atmospheric neutrino experiments will also be sensitive to a
broad range of physics and thus to new and unexpected phenomena. We discuss
here the physics which can be done by new solar and atmospheric neutrino
experiments and what we believe to be the highest priorities for the next
generation of detectors.

Peculiarities in produced particles emission in 208Pb + Ag(Br)
  interactions at 158 A GeV/c

abstract:
  The angular structures of particles produced in 208Pb induced collisions with
Ag(Br) nuclei in an emulsion detector at 158 A GeV/c have been investigated.
Nonstatistical ring-like substructures in azimuthal plane of the collision have
been found and their parameters have been determined. The indication on the
formation of the ring-like substructures from two symmetrical emission cones -
one in the forward and other in the backward direction in the center-of mass
system have been obtained. The ring-like substructures parameters have been
determined. The experimental results are in an agreement with I.M. Dremin idea,
that mechanism of the ring-like substructures formation in nuclear collisions
is similar to that of Cherenkov electromagnetic radiation.

Measurement of $\bm{\sigma (p \bar p \to Z) \cdot}$Br$\bm{(Z \to \tau
  \tau)}$ at $\bm{\sqrt{s}=}$1.96 TeV

abstract:
  We present a measurement of the cross section for $Z$ production times the
branching fraction to $\tau$ leptons, $\sigma \cdot$Br$(Z\to \tau^+ \tau^-)$,
in $p \bar p$ collisions at $\sqrt{s}=$1.96 TeV in the channel in which one
$\tau$ decays into $\mu \nu_{\mu} \nu_{\tau}$, and the other into $\rm
{hadrons} + \nu_{\tau}$ or $e \nu_e \nu_{\tau}$.
  The data sample corresponds to an integrated luminosity of 226 pb$^{-1}$
collected with the D{\O}detector at the Fermilab Tevatron collider. The final
sample contains 2008 candidate events with an estimated background of 55%.
  From this we obtain $\sigma \cdot$Br$(Z \to \tau^+ \tau^-)=237 \pm
15$(stat)$\pm 18$(sys)$ \pm 15$(lum) pb, in agreement with the standard model
prediction.

$\Xi^-\pi^-$, and $D^{(*)-}p$, respectively.

Fermilab schedules for physics will be described. In addition to the immediate
plans, the Fermilab Long Range Plan will be cited, and the status and potential
role of a new proton source, the Proton Driver, will be described.


title:
Study of the Suppressed Decays $B^- \to [K^+\pi^-]_D K^-$ and $B^- \to
  [K^+\pi^-]_D \pi^-$

abstract:
  We report a study of the suppressed decays $B^- \to [K^+\pi^-]_D K^-$ and
$B^- \to [K^+\pi^-]_D \pi^-$, where $[K^+\pi^-]_D$ indicates that the
$K^+\pi^-$ pair originates from a neutral $D$ meson. These decay modes are
sensitive to the Unitarity Triangle angle $\phi_3$. We use a data sample
containing 275 million $B\bar{B}$ pairs recorded at the $\Upsilon(4S)$
resonance with the Belle detector at the KEKB asymmetric $e^+e^-$ storage ring.
The signal for $B^- \to [K^+\pi^-]_D K^-$ is not statistically significant, and
we set a limit $r_B < 0.27$ at 90% confidence level, where $r_B$ is the
magnitude of the ratio of amplitudes $| A(B^- \to \bar{D}^0K^-) / A(B^- \to
D^0K^-) |$. We observe a signal with $6.4\sigma$ statistical significance in
the related mode, $B^- \to [K^+\pi^-]_D \pi^-$.


title: Alternative IR geometries for TESLA with a small crossing angle

abstract:
  The formulation of hybrid crossing angle schemes has been a recent
development of the TESLA collision geometry debate. Here we report on two such
schemes, characterised by either a small vertical or horizontal beam crossing
angle.


title:
Search for an exotic S=-2, Q=-2 baryon resonance at a mass near 1862 MeV
  in quasi-real photoproduction

abstract:
  A search for an exotic baryon resonance with $S=-2, Q=-2$ has been performed
in quasi-real photoproduction on a deuterium target through the decay channel
$\Xi^- \pi^- \to \Lambda \pi^- \pi^- \to p \pi^- \pi^- \pi^-$. No evidence for
a previously reported $\Xi^{--}(1860)$ resonance is found in the $\Xi^-
\pi^-$invariant mass spectrum. An upper limit for the photoproduction cross
section of 2.1 nb is found at the 90% confidence level. The photoproduction
cross section for the $\Xi^{0}(1530)$ is found to be between 9 and 24 nb.


title: Collider Searches for Extra Dimensions

abstract:
  Searches for extra spatial dimensions remain among the most popular new
directions in our quest for physics beyond the Standard Model. High-energy
collider experiments of the current decade should be able to find an ultimate
answer to the question of their existence in a variety of models. Until the
start of the LHC in a few years, the Tevatron will remain the key player in
this quest. In this paper, we review the most recent results from the Tevatron
on searches for large, 1/TeV-size, and Randall-Sundrum extra spatial
dimensions, which have reached a new level of sensitivity and currently probe
the parameter space beyond the existing constraints. While no evidence for the
existence of extra dimensions has been found so far, an exciting discovery
might be just steps away.


title:
Search for first-generation scalar leptoquarks in ppbar collisions at
  sqrt(s)=1.96 TeV

abstract:
  We report on a search for pair production of first-generation scalar
leptoquarks (LQ) in ppbar collisions at sqrt(s)=1.96 TeV using an integrated
luminosity of 252pb-1 collected at the Fermilab Tevatron collider by the D0
detector. We observe no evidence for LQ production in the topologies arising
from LQLQbar->eqeq and LQLQbar->eqnuq, and derive 95% C.L. lower limits on the
LQ mass as a function of beta, where beta is the branching fraction for LQ->eq.
The limits are 241 and 218 GeV/c2 for beta=1 and 0.5, respectively. These
results are combined with those obtained by D0 at sqrt(s)=1.8 TeV, which
increases these LQ mass limits to 256 and 234 GeV/c2.


title: CKM Results From CLEO

abstract:
  I present recent CLEO measurements of inclusive semileptonic B decay spectra
and the branching fraction. I also report preliminary results from a combined
fit to spectral moments, which are compared to expectations in the Heavy Quark
Expansion and used to precisely determine |V_cb|.


title: Search for theta+(1540) in the Reaction K+ p -> K+ n pi+ at 11 GeV/c

abstract:
  We have studied the reaction K+ p -> K+ n pi+ using an 11 GeV/c K+ beam and
the Large Acceptance Superconducting Solenoid (LASS) multiparticle spectrometer
facility at SLAC. We put limits on the production of narrow theta+ baryons in
this reaction.


title: Evidence for Neutrino Mass: A Decade of Discovery

abstract:
  Neutrino mass and mixing are amongst the major discoveries of recent years.
  From the observation of flavor change in solar and atmospheric neutrino
experiments to the measurements of neutrino mixing with terrestrial neutrinos,
recent experiments have provided consistent and compelling evidence for the
mixing of massive neutrinos. The discoveries at Super-Kamiokande, SNO, and
KamLAND have solved the long-standing solar neutrino problem and demand that we
make the first significant revision of the Standard Model in decades. Searches
for neutrinoless double-beta decay probe the particle nature of neutrinos and
continue to place limits on the effective mass of the neutrino. Possible signs
of neutrinoless double-beta decay will stimulate neutrino mass searches in the
next decade and beyond. I review the recent discoveries in neutrino physics and
the current evidence for massive neutrinos.


title: Future Muon Dipole Moment Measurements

abstract:
  From the famous experiments of Stern and Gerlach to the present, measurements
of magnetic dipole moments, and searches for electric dipole moments of
``elementary'' particles have played a major role in our understanding of
sub-atomic physics. In this talk I discuss the progress on measurements and
theory of the magnetic dipole moment of the muon. I also discuss a new proposal
to search for a permanent electric dipole moment (EDM) of the muon and put it
into the more general context of other EDM searches. These experiments, along
with searches for the lepton flavor violating decays $\mu \to e \gamma$ and
$\mu^- + A \to e^- + A$, provide a path to the high-energy frontier through
precision measurements.


title:
Measurement of the doubly Cabibbo suppressed decay $D^0 \to K^+\pi^-$
  and a search for charm mixing

abstract:
  We present an analysis of the decay $D^0 \to K^+\pi^-$ based on FOCUS data.
  From a sample of 234 signal events, we find a branching ratio of
$\frac{\Gamma(D^0 \to K^+\pi^-)}{\Gamma(D^0 \to K^-\pi^+)} =
(0.429^{+0.063}_{-0.061}\pm 0.027)%$ under the assumptions of no mixing and no
CP violation. Allowing for CP violation, we find a branching ratio of $(0.429
\pm 0.063 \pm 0.028)%$ and a \textit{CP} asymmetry of $0.18 \pm 0.14 \pm 0.04$.
The branching ratio for the case of mixing with no CP violation is
$(0.381^{+0.167}_{-0.163} \pm 0.092)%$. We also present limits on charm mixing.


title: Spin effects in large rapidity neutral pion production at STAR

abstract:
  First measurements of large Feynman x (x_F) neutral pion production in
polarized proton collisions at sqrt(s)=200 GeV were reported previously. Cross
section measurements at <eta>=3.3 and 3.8$ and analyzing power (A_N)
measurements at <eta>=3.8 were completed for 0.3 < x_F < 0.6. The cross section
was found to be consistent with next-to-leading order perturbative QCD
calculations. In that framework, the dominant subprocess is partonic collisions
of valence quarks on low Bjorken-x gluons. The A_N was found to be large and
positive and increasing with x_F, and consistent with phenomonological
calculations based on the Collins effect, the Sivers effect and initial-state
and final-state higher twist contributions. Subsequent data have been acquired
with transverse polarized proton collisions at RHIC at sqrt(s)=200 GeV. The
status of the analysis and preliminary results will be presented.


title:
A new measurement of J/psi suppression in Pb-Pb collisions at 158 GeV
  per nucleon

abstract:
  We present a new measurement of J/psi production in Pb-Pb collisions at 158
GeV/nucleon, from the data sample collected in year 2000 by the NA50
Collaboration, under improved experimental conditions with respect to previous
years. With the target system placed in vacuum, the setup was better adapted to
study, in particular, the most peripheral nuclear collisions with unprecedented
accuracy. The analysis of this data sample shows that the (J/psi)/Drell-Yan
cross-sections ratio measured in the most peripheral Pb-Pb interactions is in
good agreement with the nuclear absorption pattern extrapolated from the
studies of proton-nucleus collisions. Furthermore, this new measurement
confirms our previous observation that the (J/psi)/Drell-Yan cross-sections
ratio departs from the normal nuclear absorption pattern for semi-central Pb-Pb
collisions and that this ratio persistently decreases up to the most central
collisions.


title:
Branching Fractions and CP Asymmetries in B0 -> pi0pi0, B+ -> pi+pi0 and
  B+ -> K+pi0 Decays and Isospin Analysis of the B -> pipi System

abstract:
  Based on a sample of 227 million BBbar pairs collected by the BaBar detector
at the PEP-II asymmetric-energy B Factory at SLAC, we measure the branching
fraction B(B0 -> pi0pi0) = (1.17 +- 0.32 +- 0.10) x 1e-6, and the asymmetry
C(pi0pi0) = -0.12 +- 0.56 +- 0.06. The B0 -> pi0pi0 signal has a significance
of 5.0 sigma. We also measure B(B+ -> pi+pi0) = (5.8 +- 0.6 +- 0.4) x 1e-6,
B(B+ -> K+pi0) = (12.0 +- 0.7 +- 0.6) x 1e-6, and the charge asymmetries
A(pi+pi0) = -0.01 +- 0.10 +- 0.02 and A(K+pi0) = 0.06 +- 0.06 +- 0.01. Using
isospin relations we find an upper bound on the angle difference |alpha -
alpha(eff)| of 35 degrees at the 90% C.L.


title: Search for CP Violation in Charged-Xi and Lambda Hyperon Decays

abstract:
  We have compared the proton and antiproton angular distributions in 117
million Xi-minus -> Lambda + pi-minus -> proton + pi-minus + pi-minus and 41
million anti-Xi-minus -> anti-Lamba + pi-plus -> antiproton + pi-plus + pi-plus
decays using a subset of the data from the HyperCP experiment (E871) at
Fermilab. We find no evidence of CP violation, with the direct-CP-violating
parameter $A_{\Xi\Lambda} = \frac{\alpha_{\Xi}\alpha_{\Lambda} -
\bar{\alpha}_{\Xi}\bar{\alpha}_{\Lambda}}{\alpha_{\Xi}\alpha_{\Lambda} +
\bar{\alpha}_{\Xi}\bar{\alpha}_{\Lambda}} =
[0.0+/-5.1(stat)+/-4.4(syst)]{\times}10^{-4}$.


title: Observation of B+ --> K1(1270)+ gamma

abstract:
  We report the observation of the radiative decay B+ --> K1(1270)+ gamma using
a data sample of 140 fb-1 taken at the Upsilon(4S) resonance with the Belle
detector at the KEKB e+e- collider. We find the branching fraction to be Br(B+
--> K1(1270)+ gamma) = (4.3 +- 0.9(stat.) +- 0.9(syst.)) x 10-5 with a
statistical significance of 7.3sigma. We find no significant signal for B+ -->
K1(1400)+ gamma and set an upper limit Br(B+ --> K1(1400)+ gamma) < 1.5 x 10-5
at the 90% confidence level. We also measure inclusive branching fractions for
B+ --> K+ pi+ pi- gamma and B0 --> K0 pi+ pi- gamma in the mass range 1 GeV/c^2
< M(K+(0)pi+pi-) < 2 GeV/c^2.


title:
Measurement of Branching Fraction and Dalitz Distribution for
  B0->D(*)+/- K0 pi-/+ Decays

abstract:
  We present measurements of the branching fractions for the three-body decays
B0 -> D(*)-/+ K0 pi^+/-$ and their resonant submodes $B0 -> D(*)-/+ K*+/- using
a sample of approximately 88 million BBbar pairs collected by the BABAR
detector at the PEP-II asymmetric energy storage ring.
  We measure:
  B(B0->D-/+ K0 pi+/-)=(4.9 +/- 0.7(stat) +/- 0.5 (syst)) 10^{-4}
  B(B0->D*-/+ K0 pi+/-)=(3.0 +/- 0.7(stat) +/- 0.3 (syst)) 10^{-4}
  B(B0->D-/+ K*+/-)=(4.6 +/- 0.6(stat) +/- 0.5 (syst)) 10^{-4}
  B(B0->D*-/+ K*+/-)=(3.2 +/- 0.6(stat) +/- 0.3 (syst)) 10^{-4}
  From these measurements we determine the fractions of resonant events to be :
f(B0-> D-/+ K*+/-) = 0.63 +/- 0.08(stat) +/- 0.04(syst) f(B0-> D*-/+ K*+/-) =
0.72 +/- 0.14(stat) +/- 0.05(syst)


title:
Further study of double charmonium production in e+ e- annihilation at
  Belle

abstract:
  We report a new analysis of double charmonium production in e+ e-
annihilation using a data sample collected by the Belle experiment. We confirm
our previous observation of the processes e+ e- -> J/psi eta_c (chi_c0,
eta_c(2S)) and perform an angular analysis for these processes. Processes of
the type e+ e- -> psi(2S) (c cbar)_resonant are observed for the first time. We
also observe a new charmonium state - X(3940), produced in the process e+ e- ->
J/psi X(3940).


title: Search for Anomalous Kinematics in ttbar Dilepton Events at CDF II

abstract:
  We report on a search for anomalous kinematics of ttbar dilepton events in
ppbar collisions at sqrt{s}=1.96 TeV using 193 {pb}^{-1} of data collected with
the CDF II detector. We developed a new a priori technique designed to isolate
the subset in a data sample revealing the largest deviation from standard model
(SM) expectations and to quantify the significance of this departure. In the
four-variable space considered, no particular subset shows a significant
discrepancy and we find that the probability of obtaining a data sample less
consistent with the SM than what is observed is 1.0-4.5%.


title:
Measurements of Branching Fractions and CP Asymmetries in B-> etah
  Decays

abstract:
  We report measurements of B to pseudoscalar-pseudoscalar decays with at least
one eta meson in the final state using 140 fb^{-1} of data collected by the
Belle detector at KEKB e^+ e^- collider. We observe the decay B^+-> eta pi^+
and find evidence of B^+-> eta K+; the measured branching fractions are B(B^+->
eta pi^+)=(4.8^{+0.8}_{-0.7}(stat) +- 0.3(sys))*10^{-6} and B(B^+-> eta
K^+)=(2.1 +- 0.6(stat)+- 0.2(sys))*10^{-6}. Their corresponding CP violating
asymmetries are measured to be 0.07+- 0.15 (stat) +- 0.03(sys) for eta pi^+-
and -0.49+- 0.31 (stat) +- 0.07(sys) for eta K^+-. No significant signals are
found for neutral B->eta h decays. We report the following upper limits on
branching fractions at the 90% confidence level: B(B-> eta K^0 < 2.0* 10^{-6},
B(B-> eta pi0)<2.5*10^{-6} and B(B-> eta eta) <2.0*10^{-6}.


title: H1 Diffractive Structure Function Measurements and QCD Fits

abstract:
  Measurements of diffractive structure functions in ep collisions and
diffractive parton densities extracted from QCD fits are presented.


title: Four Sorts of Mesons

abstract:
  This report reviews the extensive spectrum of light non-strange qbar-q states
up to a mass of 2400 MeV from Crystal Barrel and PS172 data on pbar-p ->
Resonance -> A + B in 17 final states. For I=0, C=+1, the spectrum is complete
and very secure. Glueball candidates fo(1500), fo(2100), f_2(1950) and
eta(2190) are reviewed and also hybrid candidates eta_2(1870) and pi_2(1880). A
fourth category of anomalously light 0+ mesons is made of sigma(540),
kappa(750), a_0(980) and f_0(980).


title: Status and expected performance of the LHCb experiment

abstract:
  LHCb is a dedicated b-physics experiment at the future LHC collider. Its
construction has started and it will be ready to take data from the start of
LHC operation, scheduled in 2007, and directly at its full physics potential.
LHCb will benefit from an unprecedented source of b-hadrons, provided by LHC,
to improve substantialy precision measurements of CP violation parameters in
many different and complementary channels. The detector provides good particle
identification, vertexing and has an efficient and flexible trigger. Its status
and expected performance are reviewed.


title: CP Violation, an experimental perspective

abstract:
  I present a review of current and near-future experimental investigations of
CP violation. In this review, I cover limits on particle electric dipole
moments (EDMs) and CP violation studies in the K and B systems. The wealth of
results from the new B factories provide impressive constraints on the CKM
quark mixing matrix elements. Current and future measurements are focusing on
processes dominated by loop diagrams, which probe physics at high mass scales
in low-energy experiments.


title: An Experimental Review of the $\Theta^+$ Pentaquark

abstract:
  Evidence for the $\Theta^+$ pentaquark is still sketchy at the present time.
This state, if it exists, has a small width and consequently a small production
cross section. No single experiment has overwhelming evidence for the
$\Theta^+$ and some non-observations of the $\Theta^+$ are difficult to
understand unless this exotic baryon also has an exotic production mechanism.
However, new data from the LEPS and CLAS collaborations with higher statistics
are on the way, which will likely resolve the question of whether the
$\Theta^+$ exists.


title: Beam Related Systematics in Higgs Boson Mass Measurement

abstract:
  The effect of beam related systematics, namely uncertainty in the beam energy
and differential luminosity spectrum measurements and beam energy spread on the
precision of the Higgs boson mass measurement at a future linear e+e- collider
is investigated.


title:
Measurement of the Cross Section for Prompt Diphoton Production in
  p-pbar Collisions at sqrt(s) = 1.96 TeV

abstract:
  We report a measurement of the rate of prompt diphoton production in
$p\bar{p}$ collisions at $\sqrt{s}=1.96 ~\hbox{TeV}$ using a data sample of 207
pb$^{-1}$ collected with the upgraded Collider Detector at Fermilab (CDF II).
The background from non-prompt sources is determined using a statistical method
based on differences in the electromagnetic showers. The cross section is
measured as a function of the diphoton mass, the transverse momentum of the
diphoton system, and the azimuthal angle between the two photons and is found
to be consistent with perturbative QCD predictions.


title:
Search for a Charged Partner of the X(3872) in the B Meson Decay B -->
  X- K, X- --> J/psi pi- pi0

abstract:
  We search for a charged partner of the X(3872) in the decay B --> X- K, X-
--> J/psi pi- pi0, using 234 million BBbar events collected at the Y(4S)
resonance with the BaBar detector at the PEP-II e+e- asymmetric-energy storage
ring. The resulting product branching fraction upper limits are BR(B0 --> X-
K+, X- --> J/psi pi- pi0) < 5.4 x 10(-6) and BR(B- --> X- K0bar,X- --> J/psi
pi- pi0) < 22 x 10(-6) at the 90% confidence level.


title: The NuMI Neutrino Beam at Fermilab

abstract:
  The Neutrinos at the Main Injector (NuMI) facility at Fermilab is due to
begin operations in late 2004. NuMI will deliver an intense muon neutrino beam
of variable energy 2-20 GeV directed into the Earth at 58 mrad for short (~1
km) and long (~700-900 km) baseline experiments. Several aspects of the design
are reviewed, as are potential upgrade requirements to the facility in the
event a Proton Driver is built at Fermilab to enhance the neutrino flux.


title: Expectations from LHC and LC on Top Physics

abstract:
  The current status of top quark studies at the Large Hadron Collider (LHC)
and at the Linear Collider (LC) is summarized. Expectations on the measurements
of the top mass, couplings and decays, of the top spin polarization and of the
single top production are here reviewed.


title: Measurement of gamma and 2 beta + gamma

abstract:
  We report on the initial measurements of the angle gamma and the sum of
angles 2 beta + gamma of the Unitarity Triangle. When compared with indirect
information on the value of gamma from other measurements of CKM parameters,
the measurement of these angles will provide a precise test of Standard Model
predictions, as statistics increase. There are several methods for directly
measuring gamma and 2 beta + gamma. We report on the status of each of these
techniques, and the resulting constraints on the values of these angles.


title:
Measurement of the Strong Coupling alpha_S from the Four-Jet Rate in
  e+e- annihilation

abstract:
  Data from e+e- annihilation into hadrons at centre-of-mass energies between
91 GeV and 209 GeV are used to study the four-jet rate as a function of the
Durham algorithm's resolution parameter y_cut. The four-jet rate is compared to
next-to-leading order calculations that include the resummation of large
logarithms. The strong coupling measured from the four-jet rate is 0.1208
+-0.0006(stat.)+-0.0021(exp.)+-0.0019(had.)+-0.0024(scale) in agreement with
the world average.


title:
Final Results from phase II of the Mainz Neutrino Mass Search in Tritium
  $\beta$ Decay

abstract:
  The paper reports on the improved Mainz experiment on tritum $\beta$
spectroscopy which yields a 10 times' higher signal to background ratio than
before. The main experimental effects and systematic uncertainties have been
investigated in side experiments and possible error sources have been
eliminated. Extensive data taking took place in the years 1997 to 2001. A
residual analysis of the data sets yields for the square of the electron
antineutrino mass the final result of $m^2(\nu_e)=(-0.6 \pm 2.2_{\rm{stat}} \pm
2.1_{\rm{syst}})$ eV$^2$/c$^4$. We derive an upper limit of $m(\nu_e)\leq 2.3$
eV/c$^2$ at 95% confidence level for the mass itself.


title: Measurement of the Lifetime Difference Between B_s Mass Eigenstates

abstract:
  We present measurements of the lifetimes and polarization amplitudes for B_s
--> J/psi phi and B_d --> J/psi K*0 decays. Lifetimes of the heavy (H) and
light (L) mass eigenstates in the B_s system are separately measured for the
first time by determining the relative contributions of amplitudes with
definite CP as a function of the decay time. Using 203 +/- 15 B_s decays, we
obtain tau_L = (1.05 +{0.16}/-{0.13} +/- 0.02) ps and tau_H = (2.07
+{0.58}/-{0.46} +/- 0.03) ps. Expressed in terms of the difference DeltaGamma_s
and average Gamma_s, of the decay rates of the two eigenstates, the results are
DeltaGamma_s/Gamma_s = (65 +{25}/-{33} +/- 1)%, and DeltaGamma_s = (0.47
+{0.19}/-{0.24} +/- 0.01) inverse ps.


title:
Measurement of the gamma gamma -> pi+ pi- and gamma gamma -> K+ K-
  processes at energies of 2.4 - 4.1 GeV

abstract:
  We have measured pi+pi- and K+K- production in two-photon collisions using
87.7 /fb of data collected with the Belle detector at the asymmetric energy
e+e- collider KEKB. The cross sections are measured to high precision in the
two-photon center-of-mass energy (W) range between 2.4 GeV < W < 4.1 GeV and
angular region |cos theta^{*}| < 0.6. The cross section ratio
sigma(gammagamma->K+K-)/sigma(gammagamma->pi+pi-) is measured to be 0.89 +-
0.04(stat) +- 0.15(syst) in the range of 3.0 GeV < W < 4.1 GeV, where the ratio
is energy independent. We observe a sin^{-4} theta^{*} behavior of the cross
section in the same W range. Production of chi_{c0} and chi_{c2} mesons is
observed in both gammagamma -> pi+pi- and gammagamma -> K+K- modes.


title:
A Theory of Pattern Recognition for the Discrimination between Muon and
  Electron in the Super-Kamiokande

abstract:
  The standard Super-Kamiokande analysis uses an estimator for particle
identification by which it discriminates electrons (electron nutrinos) from
muons (muon nutrinos). Use of this estimator has led to the claim of a
significant deficiency of muons (muon nutrinos), suggesting the existence of
neutrino oscillations. We investigate three areas of concern for the
Super-Kamiokande estimator: the separation of the spatial part from the angular
part in the probability functions, the neglect of fluctuations in the Cherenkov
light in different physical processes due to the charged particles concerned,
and the point-like approximation for the emission of Cherenkov light. We show
that the first two factors are important for the consideration of stochastic
processes in the generation of the Cherenkov light, and that the point-like
assumption oversimplifies the estimation of the Cherenkov light quantities. We
develop a new discrimination procedure for separating electron neutrinos from
muon neutrinos, based on detailed simulations carried out with GEANT~3.21 and
with newly derived mean angular distribution functions for the charged
particles concerned (muons and electrons/positrons), as well as the
corresponding functions for the relative fluctuations. These angular
distribution functions are constructed introducing a ``moving point''
approximation. The application of our procedure between the discrimination
between electron and muon to the analysis of the experimental data in SK will
be made in a subsequent paper.


title: Sudbury Neutrino Observatory Results

abstract:
  The Sudbury Neutrino Observatory uses 1000 tonnes of heavy water in an
ultra-clean Cherenkov detector situated 2 km underground in Ontario, Canada to
study neutrinos from the Sun and other astrophysical sources. The Charged
Current (CC) reaction on deuterium is sensitive only to electron neutrinos
whereas the Neutral Current (NC) is equally sensitive to all active neutrino
types. By measuring the flux of neutrinos from 8B decay in the Sun with the CC
and NC reactions it has been possible to establish clearly, through an
appearance measurement, that electron neutrinos change to other active neutrino
types, properties that are beyond the Standard Model of elementary particles.
The observed total flux of active neutrinos agrees well with solar model flux
calculations for 8B. This provides a clear answer to the "Solar Neutrino
Problem". When these results are combined with other measurements, the
oscillation of massive neutrinos is strongly defined as the primary mechanism
for flavor change and oscillation parameters are well constrained.

  Measurement of Orbitally Excited D-Mesons at CDF II Igor V. Gorelov (For the
CDF Collaboration)
  Talk given on behalf of the CDF Collaboration at the First Meeting of the APS
Topical Group on Hadronic Physics, GHP 2004, 24-26 October 2004, FERMILAB.
Results on the first measurement of orbitally excited neutral D-meson states,
D*_2 and D_1, produced in hadron collisions at Tevatron are presented. Using
data from the displaced track trigger, CDF II collects the largest world sample
of these states in decay modes D*+ pi-, D+ pi-. Masses and widths of both
states have been measured with precision better than or comparable to the world
average.


title:
Measurement of Branching Fractions and Charge Asymmetries for Exclusive
  B Decays to Charmonium

abstract:
  We report measurements of branching fractions and charge asymmetries of
exclusive decays of neutral and charged B mesons into two-body final states
containing a charmonium state and a light strange meson. The charmonium mesons
considered are J/Psi, Psi(2S) and Chi_c1, and the light meson is either K or
K*. We use a sample of about 124 million BBbar events collected with the BABAR
detector at the PEP-II storage ring at the Stanford Linear Accelerator Center.


title: QCD physics with polarized antiprotons at GSI

abstract:
  A polarized antiproton beam at the Facility for Antiproton and Ion Research,
proposed by the PAX collaboration, will open a window to new physics uniquely
accessible at the new High Energy Storage Ring. Our proposal to realize an
asymmetric collider, in which polarized protons with momenta of about 3.5 GeV/c
collide with polarized antiprotons with momenta up to 15 GeV/c, is well--suited
to perform a direct measurement of the transversity distribution function
$h_1$. In this report we summarize the outcome of various working group
meetings within the PAX collaboration. The overall machine setup at the HESR,
proposed by the PAX collaboration, is described along with the associated PAX
experimental program.


title: Measurement of B(Y(nS) -> mu+ mu-) at CLEO

abstract:
  The decay branching fractions of the three narrow Upsilon resonances to mu+
mu- have been measured by analyzing about 4.3 1/fb e+e- data collected with the
CLEO III detector. The branching fraction B(Y(1S) -> mu+ mu-) = (2.49 +- 0.02
+- 0.07)% is consistent with the current world average but B(Y(2S) -> mu+ mu-)
= (2.03 +- 0.03 +- 0.08)% and B(Y(3S) -> mu+ mu-) = (2.39 +- 0.07 +- 0.10)% are
significantly larger than prior results. These new muonic branching fractions
imply a narrower total decay width for the Y(2S) and Y(3S) resonances and lower
other branching fractions that rely on these decays in their determination.

Radiative Penguin Decays of B Mesons: Measurements of B -> K* gamma, B
  -> K2*(1430) gamma, and Search for B0 -> phi gamma

abstract:
  Electromagnetic radiative penguin decays of the B meson were studied with the
BaBar detector at SLAC's PEP-II asymmetric-energy B Factory. Branching
fractions and isospin asymmetry of the decay B -> K* gamma, branching fractions
of B -> K2*(1430) gamma, and a search for B0 -> phi gamma are presented. The
decay rates may be enhanced by contributions from non-standard model processes.


title:
Dalitz analysis of the three-body charmless decays B+=>K+Pi+Pi- and
  B+=>K+K+K-

abstract:
  We report results on the Dalitz analysis of three-body charmless B+=>K+Pi+Pi-
and B+=>K+K+K- decays based on a 140 fb$^{-1}$ data sample collected with the
Belle detector. Measurements of branching fractions for quasi-two-body decays
to scalar-pseudoscalar states: B+ => f0(980)K+, B+ => K*_0(1430)^0 Pi+, and to
vector-pseudoscalar states: B+ => K*(892)^0 Pi+, B+ => rho(770)K+, B+ =>
phi(1020)K+ are presented. Upper limits on decays to some pseudoscalar-tensor
final states are reported. We also report the measurement of the B+ => chi_c0
K+ branching fraction in two chi_c0 decays channels: chi_c0 => Pi+Pi- and
chi_c0 => K+K-.


title:
Limit on the B0->rho0rho0 Branching Fraction and Implications for the
  CKM Angle alpha

abstract:
  We search for the decay B0 -> rho0 rho0 in a data sample of about 227 million
Upsilon(4S)-> BBbar decays collected with the BABAR detector at the PEP-II
asymmetric-energy e+e- collider at SLAC. We find no significant signal and set
an upper limit of 1.1*10^-6 at 90% CL on the branching fraction. As a result,
the uncertainty due to penguin contributions on the CKM unitarity angle alpha
measured in B -> rho rho decays is 11 degrees at 68% CL.


title: New Particles from Belle

abstract:
  I report recent results on hidden charm spectroscopy from Belle. These
include: observation of a near-threshold enhancement in the omega-J/psi
invariant mass distribution for exclusive B-->K omega J/psi decays; evidence
for the decay X(3872)-->pi+pi-pi0 J/psi, where the pi+pi-pi0 invariant mass
distribution has a strong peak between 750 MeV and the kinematic limit of 775
MeV, suggesting that the process is dominated by the sub-threshold decay
X-->omega J/psi; and the observation of a peak near 3940 MeV in the J/psi
recoil mass spectrum for the inclusive continuum process e+e- --> J/psi X. The
results are based on a study of a 287 fb-1 sample of e+e- annihilation data
collected at center- of-mass energies around the Upsilon(4S) in the Belle
detector at the KEKB collider.


title:
Observation of an Isotriplet of Excited Charmed Baryons Decaying to
  $\Lambda_c^+ \pi$

abstract:
  We report the observation of an isotriplet of excited charmed baryons,
decaying into Lambda_c+ pi-, Lambda_c+ pi0 and Lambda_c+ pi+. We measure the
mass differences M(Lambda_c+ pi)-M(Lambda_c+) and widths to be 515.4 +3.2-3.1
+2.1-6.0 MeV/c^2, 61 +18-13 +22-13 MeV for the neutral state; 505.4 +5.8-4.6
+12.4-2.0 MeV/c^2, 62 +37-23 +52-38 MeV for the charged state and 514.5
+3.4-3.1 +2.8-4.9 MeV/c^2, 75 +18-13 +12-11 MeV for the doubly charged state,
where the uncertainties are statistical and systematic, respectively. These
results are obtained from a 281 /fb data sample collected with the Belle
detector near the Upsilon(4S) resonance, at the KEKB asymmetric energy e+e-
collider.


title: Properties of the DsJ states

abstract:
  Recent measurements involving the newly discovered D_sJ particles are
reported. The results of D_sJ production and decay branching fraction
measurements are shown. Possible spin-parity and quark content assignments of
D_sJ mesons are discussed. The results are based on a large data sample
recorded by the Belle detector at the KEKB e^+ e^- collider.


title:
Measurement of the J/Psi Meson and b-Hadron Production Cross Sections in
  ppbar Collisions at sqrt s = 1960 GeV

abstract:
  We present a new measurement of the inclusive and differential production
cross sections of $J/\psi$ mesons and $b$-hadrons in proton-antiproton
collisions at $\sqrt{s}=1960$ GeV. The data correspond to an integrated
luminosity of 39.7 pb$^{-1}$ collected by the CDF Run II detector. We find the
integrated cross section for inclusive $J/\psi$ production for all transverse
momenta from 0 to 20 GeV/$c$ in the rapidity range $|y|<0.6$ to be $4.08 \pm
0.02 (stat)^{+0.36}_{-0.33} (syst) \mu {\rm b}$. We separate the fraction of
$J/\psi$ events from the decay of the long-lived $b$-hadrons using the lifetime
distribution in all events with $p_T(J/\psi) > 1.25$ GeV/$c$. We find the total
cross section for $b$-hadrons, including both hadrons and anti-hadrons,
decaying to $J/\psi$ with transverse momenta greater than 1.25 GeV/$c$ in the
rapidity range $|y(J/\psi)|<0.6$, is $ 0.330 \pm 0.005 (stat)
^{+0.036}_{-0.033} (syst) ~\mu{\rm b}$. Using a Monte Carlo simulation of the
decay kinematics of $b$-hadrons to all final states containing a $J/\psi$, we
extract the first measurement of the total single $b$-hadron cross section down
to zero transverse momentum at $\sqrt{s}=1960$ GeV. We find the total single
$b$-hadron cross section integrated over all transverse momenta for $b$-hadrons
in the rapidity range $|y|<0.6$ to be $ 17.6 \pm 0.4 (stat)^{+2.5}_{-2.3}
(syst) \mu{\rm b}$.


title: Study of B0 -> \bar{D}(*)0 pi+ pi- decays

abstract:
  We report the results of a study of neutral B decays to the $D^0 \pi^+ \pi^-$
and $D^{*0} \pi^+ \pi^-$ final states using complete $D^{(*)0}$ reconstruction.
The contributions from two-body $B\to D^{**} \pi$ with narrow ($j_q=3/2$)
$D^{**}$ states and $B\to D^{(*)}\rho, D^{(*)} f_2, D^{(*)}\sigma$ decays have
been determined. All results are preliminary, and are based on a large data
sample collected in the Belle experiment at the KEKB $e^+e^-$ collider.


title: Averages of b-hadron Properties as of Summer 2004

abstract:
  This article reports world averages for measurements on b-hadron properties
obtained by the Heavy Flavor Averaging Group (HFAG) using the available results
as of summer 2004 conferences. In the averaging, the input parameters used in
the various analyses are adjusted (rescaled) to common values, and all known
correlations are taken into account. The averages include b-hadron lifetimes,
B-oscillation (mixing) parameters, semileptonic decay parameters, rare decay
branching fractions, and CP violation measurements.


title: Experimental Evidence for the Pentaquark

abstract:
  The present experimental evidence for the existence of light pentaquarks is
reviewed, including both positive and null results. I also discuss the CLAS
experiments at Jefferson Laboratory that are forthcoming in the near future to
address questions regarding existence, mass, width, and other quantum numbers
of these five-quark baryon states.


title: Decays of the Upsilon(1S) into a Photon and Two Charged Hadrons

abstract:
  Using the CLEO III detector we report on a new study of exclusive radiative
Upsilon(1S) decays into the final states gamma pi^+ pi^-, gamma K^+ K^- and
gamma p anti-p. We present branching ratios for the decay modes Upsilon(1S) to
gamma f_2(1270), Upsilon(1S) to gamma f_2'(1525), and Upsilon(1S) to gamma
f_0(1710) with f_0(1710) to K^+ K^-.


title:
Single Spin Asymmetry in High Pt Charged Hadron Production off Nuclei at
  40 GeV

abstract:
  The single transverse spin asymmetry data for the charged hadron production
in pC and pCu interactions are presented. The measurements have been performed
at FODS-2 experimental setup using 40 GeV/c IHEP polarized proton beam. The
hadron transverse momentum range is from 0.5 GeV/c up to 4 GeV/c. The data
obtained off the nuclear targets are compared with the proton target data
measured earlier with the same experimental setup and with the data of other
experiments.


title: Reviewing the Evidence for Pentaquarks

abstract:
  Several experimental groups have reported evidence for baryons with flavor
exotic quantum numbers that cannot be explained as $qqq$ bound states but
require a minimum of five quarks -- $qqqq \bar q$. These pentaquark states
include the $\theta^{+}$, the $\Xi^{--}$ and the $\theta_{c}$. The reported
widths of these new states are consistent with experimental resolution and may
be as narrow as a few MeV/$c^2$ or less. Prior to 2003, experimental searches
for flavor exotic baryons spanning several decades yielded negative results.
There have also been a number of searches carried out since the reports of
these new pentaquark states that do not confirm their existence. This review of
both the positive and negative reports seeks to understand the current
situation regarding the experimental evidence for pentaquarks.


title: SPIN Physics at GSI

abstract:
  Polarized antiprotons produced by spin filtering with an internal polarized
gas target provide access to a wealth of single-- and double--spin observables,
thereby opening a window to physics uniquely accessible with the HESR at FAIR.
This includes a first measurement of the transversity distribution of the
valence quarks in the proton, a test of the predicted opposite sign of the
Sivers--function, related to the quark distribution inside a transversely
polarized nucleon, in Drell--Yan (DY) as compared to semi--inclusive DIS, and a
first measurement of the moduli and the relative phase of the time--like
electric and magnetic form factors G_{E,M} of the proton. In polarized and
unpolarized proton--antiproton elastic scattering open questions like the
contribution from the odd charge--symmetry Landshoff--mechanism at large |t|
and spin--effects in the extraction of the forward scattering amplitude at low
|t| can be addressed.


title: Spin Physics Progress with the STAR Detector at RHIC

abstract:
  Progress in STAR over the last two years and projections for the coming two
years are discussed. Important technical developments have been the completion
of the barrel and endcap electromagnetic calorimeters. Measurement of inclusive
pi_0 and jet A_LL over the next two years are expected to answer whether
$\Delta$G is a major contributor to the proton's spin. Transverse effects such
as Collins and Sivers functions at mid-rapidity will also be investigated.


title:
Improved Measurement of the Form Factors in the Decay Lambda_c^+ -->
  Lambda e^+ nu_e

abstract:
  Using the CLEO detector at the Cornell Electron Storage Ring, we have studied
the distribution of kinematic variables in the decay Lambda_c^+ -> Lambda e^+
nu_e. By performing a four-dimensional maximum likelihood fit, we determine the
form factor ratio, R = f_2/f_1 = -0.31 +/- 0.05(stat) +/- 0.04(syst), the pole
mass, M_{pole} = (2.21 +/- 0.08(stat) +/- 0.14(syst)) GeV/c^2, and the decay
asymmetry parameter of the Lambda_c, alpha_{Lambda_c} = -0.86 +/- 0.03(stat)
+/- 0.02(syst), for <q^2> = 0.67 (GeV/c^2)^2. We compare the angular
distributions of the Lambda_c^+ and Lambda_c^- and find no evidence for
CP-violation: A_{Lambda_c} = (alpha_{Lambda_c^+} + alpha_{Lambda_c^-})/
(alpha_{Lambda_c^+} - alpha_{Lambda_c^-}) = 0.00 +/- 0.03(stat) +/- 0.01(syst)
+/- 0.02, where the third error is from the uncertainty in the world average of
the CP-violating parameter, A_{Lambda}, for Lambda -> p pi^-.


title: The ANTARES experiment: past, present and future

abstract:
  The ANTARES collaboration aims to build a deep underwater Cherenkov neutrino
telescope in the Mediterranean Sea at 2500 m depth, about 40 km off-shore of La
Seyne sur Mer, near Toulon. The collaboration was formed in 1996 and the
experiment is currently in the construction phase. The final ANTARES detector,
consisting of 12 strings each equipped with 75 photomultiplier tubes, is
planned to be fully deployed and taking data by 2007. The project aims to
detect atmospheric and extraterrestrial neutrinos with energies above approx.
10 GeV by means of the Cherenkov light that is generated in water by charged
particles which are produced in the neutrino interactions.


title: Ultra- and extremely high energy neutrino astronomy

abstract:
  Scientific motivations for ultra- and extremely high energy neutrino
astronomy are considered. Sources and expected fluxes of EHE/UHE neutrinos are
briefly discussed. Operating and planned experiments on astrophysical neutrino
detection are reviewed focusing on deep underwater/ice Cherenkov neutrino
telescopes.


title: The Main Injector Particle Production Experiment (MIPP) at Fermilab

abstract:
  We describe the physics capabilites and status of the MIPP experiment which
is scheduled to enter its physics data taking period during December 2004-July
2005. We show some of the results obtained from the engineering run that
concluded in August 2004 and point out the unique features that make it an
ideal apparatus to study non-perturbative QCD properties.


title: $D^0$--$\bar{D}{}^0$ hadronic mixing and DCS decays from FOCUS

abstract:
  We present an analysis of the decay $D^0 \to K^+\pi^-$ from FOCUS. From a
sample of 234 events we find a branching ratio of $\frac{\Gamma(D^0 \to
K^+\pi^-)}{\Gamma(D^0 \to K^-\pi^+)} = (0.430^{+0.062}_{-0.061}\pm 0.031)%$
under the assumption of no mixing and no CP violation. We also present limits
on charm mixing.
