title: Physics at DAFNE2

abstract:
  The original plan of a vigorous program of frontier physics at LNF, based on
the phi-factory DAFNE with the KLOE detector, has not yet reached its major aim
in the study of discrete symmetries in the neutral kaon system. It has however
led to the education of a new generation of particle and accelerator
physicists. With such invaluable human resources it seems appropriate to
consider a renewed effort in achieving much improved collider performance. It
will be argued in the following that it is still possible to envision a program
of superior quality physics, requiring several years and broad enough to
justify a new collider operating at the phi-meson mass. It remains of paramount
importance that the program covers topics of fundamental interest, with many
collateral avenues well connected to the ultimate goal, a most sensitive test
of CPT invariance. The appropriate time frame for these ventures to be
successful is quite well defined, in view of the large LHC effort to begin
towards the end of the present decade.


title: Neutron Background Studies for the CRESST Dark Matter Experiment

abstract:
  The new detection concept applied for the direct WIMP search experiment
CRESST II, which enables a clear discrimination between electron recoils and
nuclear recoils, will leave neutrons as the main background. This background
will soon limit the sensitivity of the experiment and therefore become an
important issue for the next phase of CRESST. We have performed a study based
on Monte Carlo simulations to investigate how neutrons from different origins
affect CRESST and which measures have to be taken to reach the projected
sensitivity.


title: Recent Results from GMSB SUSY Searches at D0

abstract:
  Using approximately 41 pb^-1 of proton-antiproton collisions, recorded with
the D0 detector during the TeVatron Run II, this document describes the search
for minimal GMSB SUSY signal (with a neutralino as next-to-lightest
supersymmetric particle) in di-photon + missing E_T events. Since no deviation
from the Standard Model is observed, a 95% confidence level upper limit on the
signal cross-section is calculated. This is translated into a lower limit on
the neutralino mass, yielding m(chi_1^0) > 66 GeV in the context of the
Snowmass GMSB model line.


title: Apparent Excess in e+e- --> hadrons

abstract:
  We have studied measurements of the cross section for e+e- --> hadrons for
center-of-mass energies in the range 20--209 GeV. We find an apparent excess
over the predictions of the Standard Model across the whole range amounting to
more than 4\sigma. As an example, we compare the data to predictions for a
light scalar down-type quark which fit the excess well.


title:
Study of B^+/- --> J/psi pi^+/- and B^+/- --> J/psi K^+/- Decays:
  Measurement of the Ratio of Branching Fractions and Search for Direct CP
  Violation

abstract:
  We study B^+/- --> J/psi pi^+/- and B^+/- --> J/psi K^+/- decays in a sample
of about 89 million BB~ pairs collected with the BABAR detector at the PEP-II
asymmetric B-factory at SLAC. We observe a signal of 244 +/- 20 B^+/- --> J/psi
pi^+/- events and determine the ratio BF(B^+/- --> J/psi pi^+/-)/BF(B^+/- -->
J/psi K^+/-) to be [5.37 +/- 0.45 (stat.) +/- 0.11 (syst)]%. The charge
asymmetries for the B^+/- --> J/psi pi^+/- and B^+/- --> J/psi K^+/- decays are
determined to be A_pi = 0.123 +/- 0.085 (stat.) +/- 0.004 (syst.) and A_K =
0.030 +/- 0.015 (stat.) +/- 0.006 (syst.), respectively.


title: Dijet Mass Resolution at the LHC

abstract:
  At the LHC the resolution of dijet mass is compromised by the pile up of
energy from overlapping minimum bias events. Using anxillary measurements of
the jet mass and the energy in distant cones, the resolution can be improved,
as illustrated by a study of Z' of 120 GeV mass with the LHC operating at
design luminosity.


title:
Experimental Evidence of Giant Electron - Gamma Bursts Generated by
  Extensive Atmospheric Showers in Thunderclouds

abstract:
  The existence of a new phenomena - giant electron-gamma bursts is
established. The bursts are generated in thunderclouds as a result of the
combined action of runaway breakdown and extensive atmosphere showers (RB-EAS).
The experiments were fulfilled at the Tien Shan Mountain Scientific Station
using EAS-Radio installation. This specially constructed installation consists
of a wide spread EAS trigger array and a high time resolution
radiointerferometer.


title: Measurement of the e+e- -> D(*)+D(*)- cross-sections

abstract:
  We report first measurements of e+e- -> D(*)+D(*)- processes far above
threshold. The cross-sections for e+e- -> DT*+DL*- and e+e- -> D+D*T- at
sqrt{s}=10.58 GeV/c2 are measured to be 0.55 +- 0.03 +- 0.05 pb and 0.62 +-
0.03 +- 0.06 pb, respectively. We set upper limits on the cross-sections for
e+e- -> DT*+DT*-, e+e- -> DL*+DL*-, e+e- -> D+D*L- and e+e- -> D+D- processes.
The analysis is based on 88.9 fb-1 of data collected by the Belle experiment at
the KEKB e+e- asymmetric collider.


title: The First Cold Antihydrogen

abstract:
  Antihydrogen, the atomic bound state of an antiproton and a positron, was
produced at low energy for the first time by the ATHENA experiment, marking an
important first step for precision studies of atomic antimatter. This paper
describes the first production and some subsequent developments.


title: Fragmentation and Dijet Mass Resolution

abstract:
  At the LHC the overlap of minimum bias events and the jet energy deposits in
a calorimeter causes a degradation in the dijet mass resolution. Guided by QCD,
a judicious set of cuts can be developed to mitigate this degradation.


title:
Measurement of the Z-boson using e+e- -> Z gamma events at
  centre-of-mass energies above the Z pole

abstract:
  Events from the e+e- -> Zgamma process with hard initial state radiation
collected with the L3 detector at centre-of-mass energies between 183 GeV and
209 GeV are used to measure the mass of the Z boson. Decays of the Z boson into
hadrons or muon pairs are considered and the Z mass is determined to be 91.272
+- 0.032 (stat.) +- 0.033 (syst.) GeV, in agreement with the value measured at
the Z resonance. Alternatively, assuming this measured value of the Z mass, the
method determines the LEP beam energy, found to be 87 +- 34 (stat.) \pm 34
(syst.) MeV lower than the nominal value.


title:
Single- and Multi-Photon Events with Missing Energy in e+e- Collisions
  at LEP

abstract:
  Single- and multi-photon events with missing energy are selected in 619/pb of
data collected by the L3 detector at LEP at centre-of-mass energies between
189GeV and 209GeV. The cross sections of the process e^+e^- -> nu nu gamma
(gamma) are found to be in agreement with the Standard Model expectations, and
the number of light neutrino species is determined, including lower energy
data, to be N_nu = 2.98 +/- 0.05 +/- 0.04. Selection results are also given in
the form of tables which can be used to test future models involving single-
and multi-photon signatures at LEP. These final states are also predicted by
models with large extra dimensions and by several supersymmetric models. No
evidence for such models is found. Among others, lower limits between 1.5TeV
and 0.65TeV are set, at 95% confidence level, on the new scale of gravity for
the number of extra dimensions between 2 and 6.


title: Flavour Independent Search for Neutral Higgs Bosons at LEP

abstract:
  A flavour independent search for the CP-even and CP-odd neutral Higgs bosons
h and A is performed in 624/pb of data collected with the L3 detector at LEP at
centre-of-mass energies between 189 and 209GeV. Higgs boson production through
the e^+e^- -> Z h and the e^+e^- ->h A processes is considered and decays of
the Higgs bosons into hadrons are studied. No significant signal is observed
and 95% confidence level limits on the hZZ and hAZ couplings are derived as a
function of the Higgs boson masses. Assuming the Standard Model cross section
for the Higgs-strahlung process and a 100% branching fraction into hadrons, a
95% confidence level lower limit on the mass of the Higgs boson is set at
110.3GeV.


title: Searches for Exotic Higgs Bosons at LEP

abstract:
  In the Standard Model (SM), the weak gauge bosons and fermions acquire mass
through the Higgs mechanism. A lower limit on the SM Higgs mass of 114.4 GeV
was obtained from the direct search at LEP. Although a single Higgs doublet is
sufficient to explain the non-zero particle masses while keeping the theory
SU(2) gauge invariant, several extensions to this minimal model were proposed,
to which this limit does not apply. Most of the models discussed here introduce
one additional Higgs doublet and are therefore called Two Higgs doublet models
(2HDM). Several signatures predicted by such models have been searched for at
LEP using data collected at center-of-mass energies up to 209 GeV. All limits
quoted in this report are at 95% confidence level.


title:
Exotic State Searches at the SPring-8: Observation of a Pentaquark State
  Theta^+ Baryon

abstract:
  A narrow resonance peak was observed at 1.54 +/- 0.01 GeV as an exotic baryon
with strangeness S = +1 in the gamma + n going to K^+ + K^- + n reaction on
Carbon. The new state have a width smaller than 0.025 GeV and a Gaussian
significance of 4.6 sigma. It can not be interpreted as three quark state and
is consistent with the lightest member of an antidecuplet of baryons predicted
by the chiral soliton model.


title: Final Search for Lightly Ionizing Particles with the MACRO detector

abstract:
  We present the final results of a search for lightly ionizing particles using
the entire cosmic ray data set the MACRO detector collected during its
1995-2000 run. Like the original search performed with the data of 1995-96,
this search was sensitive to fractionally charged particles with an electric
charge q as low as e/5 and with velocities between approximately 0.25c and c.
The efficiency of this search was approx 70% for q = e/5 and increased rapidly
to 100% for higher charges. No candidate events were observed. This corresponds
to a 90% C. L. upper limit on their isotropic flux of 6.1x10^-16 cm^-2 sec^-1
sr^-1 which represents the most stringent experimental limit ever obtained.


title:
A Proposal for a Near Detector Experiment on the Booster Neutrino
  Beamline: FINeSSE: Fermilab Intense Neutrino Scattering Scintillator
  Experiment

abstract:
  Understanding the quark and gluon substructure of the nucleon has been a
prime goal of both nuclear and particle physics for more than thirty years and
has led to much of the progress in strong interaction physics. Still the flavor
dependence of the nucleon's spin is a significant fundamental question that is
not understood. Experiments measuring the spin content of the nucleon have
reported conflicting results on the amount of nucleon spin carried by strange
quarks. Quasi-elastic neutrino scattering, observed using a novel detection
technique, provides a theoretically clean measure of this quantity.
  The optimum neutrino beam energy needed to measure the strange spin of the
nucleon is 1 GeV. This is also an ideal energy to search for neutrino
oscillations at high $\Delta m^2$ in an astrophysically interesting region.
Models of the r-process in supernovae which include high-mass sterile neutrinos
may explain the abundance of neutron-rich heavy metals in the universe. These
high-mass sterile neutrinos are outside the sensitivity region of any previous
neutrino oscillation experiments.
  The Booster neutrino beamline at Fermilab provides the world's highest
intensity neutrino beam in the 0.5-1.0 GeV energy range, a range ideal for both
of these measurements. A small detector located upstream of the MiniBooNE
detector, 100 m from the recently commissioned Booster neutrino source, could
definitively measure the strange quark contribution to the nucleon spin. This
detector, in conjunction with the MiniBooNE detector, could also investigate
$\nu_{\mu}$ disappearance in a currently unexplored, cosmologically interesting
region.


title:
Search for possible neutrino radiative decays during the 2001 total
  solar eclipse

abstract:
  We present the results of the observations performed in the occasion of the
June 21, 2001 total solar eclipse, looking for visible photons emitted trough a
possible radiative decay of solar neutrinos. We establish lower limits for the
neutrino proper lifetimes larger than 1000 s/eV, for neutrino masses larger
than 0.01 eV.


title: The status of |Vub|

abstract:
  I survey the theoretical and experimental information available for
determination of |Vub| with inclusive and exclusive techniques. Using recent
experimental and theoretical advances, I outline a procedure in which the
inclusive information can be combined to obtain an inclusive |Vub| that
includes experimentally--derived uncertainty estimates for outstanding
theoretical corrections.


title:
Spin asymmetries for events with high p_T hadrons in DIS and an
  evaluation of the gluon polarization

abstract:
  We present a measurement of the longitudinal spin cross section asymmetry for
deep inelastic muon-nucleon interactions with two high transverse momentum
hadrons in the final state. Two methods of event classification are used to
increase the contribution of the Photon Gluon Fusion process to above 30%. The
most effective one, based on a neural network approach, provides the
asymmetries A_p(lN->lhhX)=0.030+/-0.057+/-0.010 and
A_d(lN->lhhX)=0.070+/-0.076+/-0.010. From these values we derive an averaged
gluon polarization delta(G)/G=-0.20+/-0.28+/-0.10 at an average fraction of
nucleon momentum carried by gluons eta=0.07.


title:
Upper Limit on the eta to gamma gamma gamma Branching Ratio with the
  KLOE Detector

abstract:
  We have searched for the C-violating decay eta to gamma gamma gamma in a
sample of ~ 18 million eta mesons produced in phi to eta gamma decays,
collected with the KLOE detector at the Frascati phi-factory DAFNE. No signal
is observed and we obtain the upper limit BR(eta to gamma gamma gamma) less
equal than 1.6x10^(-5) at 90 % C.L.


title:
Search for the Pentaquark State in $\psi(2S)$ and $J/\psi$ Decays to
  $K^0_SpK^-\bar n$ and $K^0_S\bar p K^+n$

abstract:
  Results are presented on $\psi(2S)$ and $J/\psi$ hadronic decays to
$K^0_SpK^-\bar n$ and $K^0_S\bar p K^+n$ final states from data samples of 14
million $\psi(2S)$ and 58 million $J/\psi$ events accumulated at the BES II
detector. No $\Theta(1540)$ signal, the pentaquark candidate, is observed, and
upper limits for ${\cal B}(\psi(2S)\to\Theta\bar\Theta\to K^0_S p K^-\bar n +
K^0_S \bar p K^+ n) < 0.84\times 10^{-5}$ and ${\cal
B}(J/\psi\to\Theta\bar\Theta\to K^0_S p K^-\bar n + K^0_S \bar p K^+ n) <
1.1\times 10^{-5}$ at the 90% confidence level are set. For single
$\Theta(1540)$ production, the upper limits determined by our analysis are also
on the order of $10^{-5}$ in both $\psi(2S)$ and $J/\psi$ decays.


title: Measurement of the Branching Fraction of J/psi --> pi+ pi- pi0

abstract:
  Using 58 million J/psi and 14 million psi' decays obtained by the BESII
experiment, the branching fraction of J/psi --> pi+ pi- pi0 is determined. The
result is (2.10+/-0.12)X10^{-2}, which is significantly higher than previous
measurements.


title: Search for neutrino radiative decays during a total solar eclipse

abstract:
  We present the results of the measurements performed in the occasion of the
2001 total solar eclipse, looking for visible photons emitted through a
possible radiative decay of solar neutrinos. We establish lower limits for the
\nu_2 and \nu_3 proper lifetimes above 10^3 s/eV, for neutrino masses larger
than 10^{-2} eV.


title:
Limit On the Neutrino Magnetic Moment Using 1496 Days of
  Super-Kamiokande-i Solar Neutrino Data

abstract:
  A search for a non-zero neutrino magnetic moment has been conducted using
1496 live days of solar neutrino data from {\SK}. Specifically, we searched for
distortions to the energy spectrum of recoil electrons arising from magnetic
scattering due to a non-zero neutrino magnetic moment. In the absence of clear
signal, we found $\mu_{\nu} \leq 3.6 \times 10^{-10}$ $\mu_{B}$ at 90% C.L. by
fitting to the Super-Kamiokande day/night spectra. The fitting took into
account the effect of neutrino oscillation on the shapes of energy spectra.
With additional information from other solar neutrino and KamLAND experiments
constraining the oscillation region, a limit of $\mu_{\nu} \leq 1.1 \times
10^{-10}$ $\mu_{B}$ at 90% C.L. was obtained.


title: General Search for New Phenomena in ep Scattering at HERA

abstract:
  A model-independent search for deviations from the Standard Model prediction
has been performed in e+p and e-p collisions at HERA using H1 data. All
experimentally measurable event topologies involving isolated electrons,
photons, muons, neutrinos and jets with high transverse momenta have been
investigated. A good agreement with the Standard Model prediction is found in
most of the event classes. A new algorithm has been developed to look for
regions with large deviations from the Standard Model in the invariant mass and
sum of transverse momenta distributions and to quantify the significance of the
fluctuations observed. The largest deviation is found in topologies with an
isolated muon, missing transverse momentum and a jet which confirms previous
observations. About 2% of hypothetical Monte Carlo experiments would produce
deviations more significant than the one observed in the corresponding
distribution of sum of transverse momenta.


title:
Search for Electron Neutrino Appearance in a 250 km Long-baseline
  Experiment

abstract:
  We present a search for electron neutrino appearance from accelerator
produced muon neutrinos in the K2K long baseline neutrino experiment. One
candidate event is found in the data corresponding to an exposure of 4.8*10^19
protons on target. The expected background in the absence of neutrino
oscillations is estimated to be 2.4+-0.6 events and is dominated by
mis-identification of events from neutral current pi^0 production. We exclude
the \nu_\mu to \nu_e oscillations at 90% C.L. for the effective mixing angle in
2-flavor approximation of sin^2(2theta_\mu_e) (~= 1/2 sin^2 2 th_13) > 0.15 at
Delta m^2_\mu_e = 2.8*10^{-3} eV^2, the best fit value of the \nu_\mu
disappearance analysis in K2K. The most stringent limit of sin^2(2theta_\mu_e)
< 0.09 is obtained at Delta m^2_\mu_e = 6*10^{-3} eV^2.


title: Semileptonic B Decays at BABAR

abstract:
  We present results on semileptonic B decays obtained with the BABAR detector.
The large data set accumulated at the PEP-II asymmetric-energy B-Factory allows
a new measurement technique, where the hadronic decay of one B meson is fully
reconstructed and the semileptonic decay of the recoiling B meson is studied.
Traditional analysis techniques of inclusive and exclusive B decays complement
this approach with very high statistics data samples. These measurements play
an important role in the tests of the description of CP violation in the
Standard Model: The determinations of the Cabibbo-Kobayashi-Maskawa matrix
elements |Vcb| and |Vub| provide constraints on the unitarity of the CKM
triangle. Furthermore, the experimental measurement of parameters of Heavy
Quark Effective Theory test the consistency of the theoretical description of
semileptonic B decays.


title: Observation of isolated high-E_T photons in deep inelastic scattering

abstract:
  First measurements of cross sections for isolated prompt photon production in
deep inelastic ep scattering have been made using the ZEUS detector at the HERA
electron-proton collider using an integrated luminosity of 121 pb^-1. A signal
for isolated photons in the transverse energy and rapidity ranges 5 < E_T^gamma
< 10 GeV and -0.7 < eta^gamma < 0.9 was observed for virtualities of the
exchanged photon of Q^2 > 35 GeV^2. Cross sections are presented for inclusive
prompt photons and for those accompanied by a single jet in the range E_T^jet
\geq 6 GeV and -1.5 \leq eta^jet < 1.8. Calculations at order alpha^3alpha_s
describe the data reasonably well.


title: B Physics at the Tevatron

abstract:
  After a five year upgrade period, the Fermilab experiments CDF and DO are
taking high quality data in Run II of the Tevatron Collider. We report on the
start-up of both detectors and present a selection of first B physics results
from the Tevatron. We also compare different B hadron producers such as the
Y(4S) with the hadron collider environment and discuss general features of B
physics at a hadron collider.


title:
Constraints on Anomalous Quaric Gauge Boson Couplings from vv gamma
  gamma and qq gamma gamma events at LEP 2

abstract:
  Anomalous quartic couplings between the electroweak gauge bosons may
contribute to the vv gamma gamma and qq gamma gamma final states produced in
e+e- collisions. This analysis uses the LEP2 OPAL data sample at centre-of-mass
energies up to 209 GeV. Event selections identify vv gamma gamma and qq gamma
gamma events in which the two photons are reconstructed within the detector
acceptance. The cross-section for the process e+e- -> qq gamma gamma is
measured. Averaging over all energies, the ratio of the observed e+e- -> qq
gamma gamma cross-section to the Standard Model expectation is R(data/SM) =
0.92 +- 0.07 +- 0.04 where the errors represent the statistical and systematic
uncertainties respectively. The vv gamma gamma and qq gamma gamma data are used
to constrain possible anomalous W+W- gamma gamma and ZZ gamma gamma couplings.
Combining with previous OPAL results from the W+W- gamma final state, the 95%
confidence level limits on the anomalous coupling parameters aoz, acz, aow and
acw are found to be:
  -0.007 GeV^-2 < aoz/Lambda^2 < 0.023 GeV^-2 -0.029 GeV^-2 < acz/Lambda^2 <
0.029 GeV^-2 -0.020 GeV^-2 < aow/Lambda^2 < 0.020 GeV^-2 -0.052 GeV^-2 <
acw/Lambda^2 < 0.037 GeV^-2 where Lamdba is the energy scale of the new
physics. Limits found when allowing two or more parameters to vary are also
presented.


title: Status of Neutrino Factory R&D within the Muon Collaboration

abstract:
  We describe the current status of the research within the Muon Collaboration
towards realizing a Neutrino Factory. We describe briefly the physics
motivation behind the neutrino factory approach to studying neutrino
oscillations and the longer term goal of building the Muon Collider. The
benefits of a step by step staged approach of building a proton driver,
collecting and cooling muons followed by the acceleration and storage of cooled
muons are emphasized. Several usages of cooled muons open up at each new stage
in such an approach and new physics opportunites are realized at the completion
of each stage.


title: Evidence for $B^+\to\omega l^+ \nu$

abstract:
  We have searched for the decay $B^+\to\omega l^+\nu$ ($l=e$ or $\mu$) in 78
fb$^{-1}$ of $\Upsilon(4S)$ data (85 million $B\bar B$ events) accumulated with
the Belle detector. The final state is fully reconstructed using the $\omega$
decay into $\pi^+\pi^-\pi^0$, combined with detector hermeticity to estimate
the neutrino momentum. A signal of $414\pm 125$ events is found in the data,
corresponding to a branching fraction of $(1.3\pm 0.4\pm 0.2\pm 0.3)\times
10^{-4}$, where the first two errors are statistical and systematic,
respectively. The third error reflects the estimated form-factor uncertainty.


title:
Search for B+/- --> [K-/+ pi+/-]_D K+/- and upper limit on the b --> u
  amplitude in B+/- --> D K+/-

abstract:
  We search for B+/- --> [K^-/+ pi+/-]_D K+/- decays, where [K-/+ pi+/-]_D
indicates that the K-/+ pi+/- pair originates from the decay of a D0 or D0bar.
Results are based on 120 million Upsilon(4S) --> B Bbar decays collected with
the BaBar detector at SLAC. We set an upper limit on the ratio R_Kpi =
{Gamma(B+ --> [K- pi+]_D K+) + Gamma(B- --> [K+ pi-]_D K-)}/
  {Gamma(B+ --> [K+ pi-]_D K+) + Gamma(B- --> [K- pi+]_D K-)} < 0.026 (90%
C.L.). This constrains the amplitude ratio r_B = |A(B- --> D0bar K-)/A(B- -->
D0 K-)| < 0.22 (90% C.L.), consistent with expectations. The small value of r_B
favored by our analysis suggests that the determination of the
Cabibbo-Kobayashi-Maskawa phase gamma from B --> D K will be difficult.


title:
Observation of the Decay B=> J/psi eta K and Search for X(3872)=> J/psi
  eta

abstract:
  We report the observation of the $B$ meson decay $B^\pm\to J/\psi \eta K^\pm$
and evidence for the decay $B^0\to J/\psi \eta K^0_S$, using {90} million
$BBbar$ events collected at the $\ensuremath{\Upsilon{(4S)}}\xspace$ resonance
with the $BaBar$ detector at the PEP-II $e^+ e^-$ asymmetric-energy storage
ring. We obtain branching fractions of $\cal{B}$$(B^\pm\to J/\psi \eta
K^{\pm}$)=$(10.8\pm 2.3(\rm{stat.})\pm 2.4(\rm{syst.}))\times 10^{-5}$ and
$\cal{B}$$(B^0\to J/\psi\eta K_{\rm{S}}^{0}$)=$(8.4\pm 2.6(\rm{stat.})\pm
2.7(\rm{syst.}))\times 10^{-5}$. We search for the new narrow mass state, the
X(3872), recently reported by the Belle Collaboration, in the decay $B^\pm\to
X(3872)K^\pm, X(3872)\to \jpsi \eta$ and determine an upper limit of
$\cal{B}$$(B^\pm \to X(3872) K^\pm \to \jpsi \eta K^\pm$) $<7.7\times 10^{-6}$
at 90% C.L.


title:
Upper limit on the decay Sigma(1385)- --> Sigma- gamma, and cross
  section for gamma Sigma- --> Lambda pi-

abstract:
  Coherent Lambda pi- production on Pb of 600 GeV Sigma- hyperons has been
studied with the SELEX facility at Fermilab. Using the Primakoff formalism, we
set a 90% CL upper limit on the radiative decay width Gamma [Sigma(1385)- -->
Sigma- gamma] < 9.5 keV, and estimate the cross section for gamma Sigma- -->
Lambda pi- at sqrt(s) = 1.385 GeV to be 56+/-16 mkb.


title: New Physics Searches with Photons in CDF

abstract:
  A brief review of searches for physics beyond the Standard Model with photons
using the CDF detector at the Tevatron is given here. These include searches
for supersymmetry, extra dimensions, excited electrons and W/Z$+\gamma$
production, as well as anomalous photon production. Recent results from CDF Run
II experiment is presented, but some results from Run I are also reviewed.


title: $e^+e^-$ Pair Production from 10 GeV to 10 ZeV

abstract:
  At very high energies, pair production ($\gamma\to e^+e^-$) exhibits many
interesting features. The momentum transfer from the target is very small, so
the reaction probes the macroscopic properties of the target, rather than
individual nuclei. Interference between interactions with different atoms
reduces the pair production cross section considerably below the Bethe-Heitler
values. At very high energies, photonuclear interactions may outnumber pair
production.
  In contrast, in crystals, the interaction amplitudes may add coherently,
greatly increasing the cross sections. Pair production in matter-free magnetic
fields is also possible. The highest energy pair production occurs at high
energy particle colliders. This article will compare pair production in these
very different regimes.


title: Systematic Analysis of High Energy Collider Data

abstract:
  These proceedings outline steps toward a systematic analysis of frontier
energy collider data: specifically, those data collected at Tevatron Runs I and
II, LEP Run II, HERA Runs I and II, and the future LHC. Algorithms designed to
understand the gross features of the data (Vista), to systematically and
model-independently search for new physics at the electroweak scale (Sleuth),
to automate tests of specific hypotheses against those data (Quaero), to turn
an existing full detector simulation into a fast simulation (TurboSim), and to
infer the physics underlying any hint observed in the data (Bard) are reviewed.
A somewhat non-conventional viewpoint is adopted throughout.


title: KLOE Results on Rare K0 Decays

abstract:
  This paper describes the current neutral Kaon dataset and physics
measurements of KLOE at DAFNE. A brief discussion on the prospects for detector
upgrades and analysis of other K0 rare decays is also included.


title: Mass Resolution Corrections at the LHC

abstract:
  The utility of jet spectroscopy at the LHC is compromised by the existence of
multiple interactions within a bunch crossing. The energy deposits from these
interactions at the design luminosity of the LHC may degrade the dijet mass
resolution unless great care is taken. Energy clusters making up the jet can be
required to have an energy flow with respect to the jet axis which resembles
QCD. In addition, subsidiary information such as the jet mass or the out of jet
cone mass or transverse momentum can be deployed so as to alleviate the adverse
effects of pileup.


title: Inclusive Semileptonic B Decays at BABAR

abstract:
  We report updates on two analyses of inclusive semileptonic B decays based on
a dataset of 89 million BB events recorded with the BABAR detector at the Y(4S)
resonance. Events are selected by fully reconstructing the decay of one B meson
and identifying a charged lepton from the decay of the other B meson. In the
first analysis, the measurement of the first and second moment of the hadronic
mass distribution in Cabibbo-favored B ->X_c l nu decays allows for the
determination of the nonperturbative parameters $\bar{\Lambda}$ and $\lambda_1$
of Heavy Quark Effective Theory (HQET) and |Vcb|. In the second analysis, the
hadronic mass distribution is used to measure the inclusive charmless
semileptonic branching fraction and to determine |Vub|.


title: Rare Kaon Decays at KTeV

abstract:
  The KTeV experiment at Fermilab has studied a wide range of rare KL decays.
In this talk I focus on the electromagnetic decays KL --> gamma* gamma(*) where
one or both photons is virtual. Recent results are also presented for searches
for the CP-violating decay KL--> pi0 ee and lepton-flavor-violating modes.


title: Measurements of J/psi --> p \bar{p}

abstract:
  The process J/\psi --> p \bar{p} is studied using 57.7 X 10^6 J/\psi events
collected with the BESII detector at the Beijing Electron Positron Collider.
The branching ratio is determined to be Br(J/\psi --> p \bar{p})=(2.26 +- 0.01
+- 0.14) X 10^{-3}, and the angular distribution is well described by
\frac{dN}{d cos\theta_p}=1+\alpha\cos^2\theta_p with \alpha = 0.676 +- 0.036 +-
0.042, where \theta_p is the angle between the proton and beam directions. The
value of \alpha obtained is in good agreement with the predictions of
first-order QCD.


title: Inclusive Lambda Production in Two-Photon Collisions at LEP

abstract:
  The reactions e^+e^- -> e^+e^- Lambda X and e^+e^- -> e^+e^- Lambda X are
studied using data collected at LEP with the L3 detector at centre-of-mass
energies between 189 and 209 GeV. Inclusive differential cross sections are
measured as a function of the lambda transverse momentum, p_t, and
pseudo-rapidity, eta, in the ranges 0.4 GeV < p_t < 2.5 GeV and |\eta| < 1.2.
The data are compared to Monte Carlo predictions. The differential cross
section as a function of p_t is well described by an exponential of the form A
exp (- p_t / <p_t>)$.


title: Measurement of Triple-Gauge-Boson Couplings of the W Boson at LEP

abstract:
  The CP-conserving triple-gauge-boson couplings, g1Z, kappa_gamma,
lambda_gamma, g5Z, kappa_Z and lambda_Z are measured using hadronic and
semi-leptonic W-pair events selected in 629 pb-1 of data collected at LEP with
the L3 detector at centre-of-mass energies between 189 and 209 GeV. The results
are combined with previous L3 measurements based on data collected at lower
centre-of-mass energies and with the results from single-W production and from
events with a single-photon and missing energy. Imposing the constraints
kappa_Z = g1Z - tan^2(theta_W) (kappa_gamma-1) and lambda_Z = lambda_gamma, we
obtain for the C and P conserving couplings the results: g1Z = 0.966 +/- 0.033
(stat.) +/- 0.015 (syst.) kappa_gamma = 1.013 +/-0.066 (stat.) +/- 0.026
(syst.) lambda_gamma = -0.021 +/- 0.035 (stat.) +/-0.017 (syst.). Results from
the analysis of fully leptonic W-pair decays are also given. All results are in
agreement with the Standard Model expectations and confirm the existence of
self-couplings among electroweak gauge bosons.


title: Muon-Pair and Tau-Pair Production in Two-Photon Collisions at LEP

abstract:
  The QED processes e^+ e^- -> e^+ e^- \mu^+ \mu^- and e^+ e^- -> e^+ e^-
\tau^+ \tau^- are studied with the L3 detector at LEP using an untagged data
sample collected at centre-of-mass energies
  161 GeV < sqrt{s} < 209 GeV. The tau-pairs are observed through the
associated decay of one tau into e\nu\nu and the other into \pi\pi\nu . The
cross sections are measured as a function of sqrt{s}. For muon pairs, the cross
section of the \gamma\gamma -> \mu^+\mu^- process is also measured as a
function of the two-photon centre-of-mass energy for 3 GeV < W_{\gamma\gamma} <
40 GeV. Good agreement is found between these measurements and the O(\alpha^4)
QED expectations. In addition, limits on the anomalous magnetic and electric
dipole moments of the tau lepton are extracted.


title: Jet-Studies and $\alpha_s$-determinations at HERA

abstract:
  Recent results from the H1 and ZEUS Collaborations on inclusive single and
multiple jet production in the neutral current deep inelastic scattering of
electrons/positrons on protons and the high energy photoproduction on protons
at HERA are reported. The results are compared with NLO QCD calculations and
have been used to determine the strong interaction coupling constant
$\alpha_s$.


title: The Character of Z-pole Data Constraints on Standard Model Parameters

abstract:
  Despite the impressive precision of the Z-pole measurements made at LEP and
SLC, the allowed region for the principle Standard Model parameters responsible
for radiative corrections (the mass of the Higgs, the mass of the top and
alpha(Mz)) is still large enough to encompass significant non-linearities. The
nature of the experimental constraints therefore depends in an interesting way
on the "accidental" relationships among the various measurements. In
particular, the fact that the Z-pole measurements favor values of the Higgs
mass excluded by direct searches leads us to examine the effects of external
Higgsstrahlung, a process ignored by the usual precision electroweak
calculations.


title: Charm Meson Spectra in e^+e^- Annihilation at 10.5 GeV c.m.e

abstract:
  Using the CLEO detector at the Cornell Electron-positron Storage Ring, we
have measured the scaled momentum spectra, dsigma/dx_p, and the inclusive
production cross sections of the charm mesons D+, D0, D*+, and D*0 in e+e-
annihilation at about 10.5 GeV center of mass energy, excluding the decay
products of B mesons. The statistical accuracy and momentum resolution are
superior to previous measurements at this energy.


title: A New Nuclear Reactor Neutrino Experiment to Measure theta 13

abstract:
  An International Working Group has been meeting to discuss ideas for a new
Nuclear Reactor Neutrino Experiment at meetings in May 2003 (Alabama), October
2003 (Munich) and plans for March 2004 (Niigata). This White Paper Report on
the Motivation and Feasibility of such an experiment is the result of these
meetings. After a discussion of the context and opportunity for such an
experiment, there are sections on detector design, calibration, overburden and
backgrounds, systematic errors, other physics, tunneling issues, safety and
outreach. There are 7 appendices describing specific site opportunities.


title: Measurement of the B --> K^* gamma Branching Fractions and Asymmetries

abstract:
  We report measurements of the radiative decay B --> K^*\gamma. The analysis
is based on a data sample containing 85.0*10^6 B meson pairs collected by the
Belle detector at the KEKB storage ring. We measure branching fractions of
Br(B^0 --> K^{*0}\gamma) = (4.01 \pm 0.21 \pm 0.17)*10^{-5} and Br(B^+ -->
K^{*+}\gamma) = (4.25 \pm 0.31 \pm 0.24)*10^{-5}, where the first and second
errors are statistical and systematic, respectively. The isospin asymmetry
between B^0 and B^+ decay widths is measured to be \Delta_{0+} = +0.012 \pm
0.044 \pm 0.026. We search for a partial rate asymmetry between CP conjugate
modes, and find A_{cp}(B --> K^*\gamma) = =0.015 \pm 0.044 \pm 0.012.


title:
Measurements of CP-violating Asymmetries in $B^{0}\to K_{s}^{0}\pi^{0}$
  Decays

abstract:
  We present a measurement of the time-dependent CP-violating (CPV) asymmetries
in $B^{0}\to K_{s}^{0}\pi^{0}$ decays based on 124 million $\Upsilon(4S)\to
B\bar{B}$ decays collected with the BaBar detector at the PEP-II
asymmetric-energy $B$ Factory at SLAC. In a sample containing $122\pm 16$
signal decays, we obtain the magnitude of the direct CPV asymmetry
$C_{K_{s}^{0}\pi^{0}} = 0.40^{+0.27}_{-0.28} \pm 0.09$ and the magnitude of the
CPV asymmetry in the interference between mixing and decay
$S_{K_{s}^{0}\pi^{0}} = 0.48^{+0.38}_{-0.47} \pm 0.06$ where the first error is
statistical and the second systematic.


title:
Limits on the Decay-Rate Difference of Neutral-B Mesons and on CP, T,
  and CPT Violation in B0-antiB0 Oscillations

abstract:
  Using events in which one of two neutral-B mesons from the decay of an Y(4S)
resonance is fully reconstructed, we set limits on the difference between the
decay rates of the two neutral-B mass eigenstates and on CP, T, and CPT
violation in B0-antiB0 mixing. The reconstructed decays, comprising both CP and
flavor eigenstates, are obtained from 88 million Y(4S) --> Banti-B decays
collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at
SLAC. We determine six independent parameters governing oscillations (Deltam,
DeltaGamma/Gamma), CPT and CP violation (Re Z, Im Z), and CP and T violation
(Im lambdaCP, |q/p|), where lambdaCP characterizes B0 and anti-B0 decays to
states of charmonium plus K0S or K0L. The results are sgn(Re
lambdaCP)xDeltaGamma/Gamma = -0.008 +/- 0.037(stat) +/- 0.018(syst)
[-0.084,0.068], |q/p| = 1.029 +/- 0.013(stat) +/- 0.011(syst) [ 1.001,1.057],
(Re lambdaCP)/|lambdaCP|xRe z = 0.014 +/- 0.035(stat) +/- 0.034(syst)
[-0.072,0.101], Im z = 0.038 +/- 0.029(stat) +/- 0.025(syst) [-0.028,0.104],
The values inside square brackets indicate the 90% confidence-level intervals.
The values of Im lambdaCP and Deltam are consistent with previous analyses and
are used as cross-checks. These measurements are in agreement with Standard
Model expectations.


title: Search for the Decay B0 -> ppbar

abstract:
  We present the result of a search for the charmless two-body baryonic decay
B^0 -> ppbar in a sample of 88 million Y(4S) -> BBbar decays collected by the
BaBar detector at the SLAC PEP-II asymmetric-energy $B$ Factory. We use
Cherenkov radiation to identify protons cleanly, and determine the signal yield
with a maximum-likelihood fit technique using kinematic and topological
information. We find no evidence for a signal and place a 90% confidence-level
upper limit of BF(B^0 -> ppbar) < 2.7 x 10^-7.


title:
An inclusive measurement of the photon energy spectrum in b->s gamma
  decays

abstract:
  We report a fully inclusive measurement of the flavour changing neutral
current decay b->s gamma in the energy range 1.8 GeV < E* < 2.8 GeV, covering
95% of the total spectrum. Using 140 fb^-1 we obtain BF(b->s gamma)= 3.55 +/-
0.32 +0.30-0.31 +0.11-0.07, where the errors are statistical, systematic and
from theory corrections. We also measure the first and second moments of the
photon energy spectrum above 1.8 GeV and obtain <E> = 2.292 +/- 0.026 +/- 0.034
GeV and <E^2>-<E>^2 = 0.0305 +/- 0.0074 +/- 0.0063 GeV^2, where the errors are
statistical and systematic.


title: KLOE Perspectives for R-Measurements at DAFNE2

abstract:
  As a future upgrade of the Frascati phi factory DAPHNE an increase of the
center-of-mass energy of the accelerator up to W=2GeV has been proposed
(DAFNE2). In this case the hadronic cross section in the energy range between
1-2 GeV can be measured with the KLOE detector. The feasibility of these
measurements and the impact on the hadronic contribution to the anomalous
magnetic moment of the muon are discussed. The possibilities for an energy scan
are compared with the radiative return technique, in which the accelerator is
running at a fixed center-of-mass energy and ISR-events are taken to lower the
invariant mass of the hadronic system.


title: Measurement of sigma(e+e- =>pi+pi-) at e+e- colliders

abstract:
  At the DAFNE-II workshop a session was devoted to the prospects of measuring
the hadronic cross section at the new DAFNE. The session included six papers,
two theoretical and four experimental ones. The theory treatises, one on the
muon anomaly and the other on measuring the hadronic cross section using
initial state radiation at $e^+e^-$ colliders, set the background for the four
experimental discussions. I summarize in the following the salient points of
the session.


title: Branching Fraction Measurements of B ->etac K Decays

abstract:
  We study the decays B+ -> etac K+ and B0 -> etac K0, where the etac is
reconstructed in the Ks K+ pi- and K+ K- pi0 decay modes. Results are based on
a sample of 86 million BBbar pairs collected with the BaBar detector at the
SLAC e+e- B Factory. We measure the branching fractions BR(B+ -> etac K+) =
(1.34 +/- 0.09 +/- 0.13 +/- 0.41) x 10^{-3} and BR(B0 -> etac K0) = (1.18 +/-
0.16 +/- 0.13 +/- 0.37) x 10^{-3}, where the first error is statistical, the
second is systematic, and the third reflects the etac branching fraction
uncertainty. In addition, we search for B -> etac K events with etac -> 2(K+K-)
and etac -> phi phi and determine the etac decay branching fraction ratios
BR(etac -> 2(K+K-))/BR(etac -> K Kbar pi) = (2.3 +/- 0.7 +/- 0.6) x 10^{-2} and
BR(etac -> phi phi)/BR(etac -> K Kbar pi) = (5.5 +/- 1.4 +/- 0.5) x 10^{-2}.


title: A Study of J/psi-->gamma gamma V(rho,phi) Decays with the BESII Detector

abstract:
  Using a sample of $58\times 10^6$ $J/\psi$ events collected with the BESII
detector, radiative decays $J/\psi\to\gamma\gamma V$, where $V=\rho$ or $\phi$,
are studied. A resonance around 1420 MeV/c$^2$ (X(1424)) is observed in the
$\gamma\rho$ mass spectrum. Its mass and width are measured to be $1424\pm
10(stat)\pm 11(sys)$ MeV/c$^2$ and $ 101.0\pm 8.8 \pm 8.8$ MeV/c$^2$,
respectively, and its branching ratio $B(J/\psi\to \gamma X(1424)\to \gamma
\gamma \rho)$ is determined to be $(1.07\pm0.17 \pm 0.11)\times 10^{-4}$. A
search for $X(1424)\to \gamma\phi$ yields a 95% C.L. upper limit $B(J/\psi\to
\gamma X(1424)\to \gamma\gamma \phi) < 0.82 \times 10^{-4}$.


title:
Neutron background at the Canfranc Underground Laboratory and its
  contribution to the IGEX-DM dark matter experiment

abstract:
  A quantitative study of the neutron environment in the Canfranc Underground
Laboratory has been performed. The analysis is based on a complete set of
simulations and, particularly, it is focused on the IGEX-DM dark matter
experiment. The simulations are compared to the IGEX-DM low energy data
obtained with different shielding conditions. The results of the study allow us
to conclude, with respect to the IGEX-DM background, that the main neutron
population, coming from radioactivity from the surrounding rock, is practically
eliminated after the implementation of a suitable neutron shielding. The
remaining neutron background (muon-induced neutrons in the shielding and in the
rock) is substantially below the present background level thanks to the muon
veto system. In addition, the present analysis gives us a further insight on
the effect of neutrons in other current and future experiments at the Canfranc
Underground Laboratory. The comparison of simulations with the body of data
available has allowed to set the flux of neutrons from radioactivity of the
Canfranc rock, (3.82 +- 0.44) x 10^{-6} cm^{-2} s^{-1}, as well as the flux of
muon-induced neutrons in the rock, (1.73 +- 0.22(stat) \+- 0.69(syst)) x
10^{-9} cm^{-2} s^{-1}, or the rate of neutron production by muons in the lead
shielding, (4.8 +- 0.6 (stat) +- 1.9 (syst)) x 10^{-9} cm^{-3} s^{-1}.


title: A New Measurement of the Weak Mixing Angle

abstract:
  The E158 experiment at SLAC has made the first measurement of parity
violation in electron-electron (Moller) scattering. We report a preliminary
result using 50% of the accumulated data sample for the right-left
parity-violating cross-section asymmetry (APV) in the elastic scattering of 45
and 48 GeV polarized electron beams with unpolarized electrons in a liquid
hydrogen target. We find APV = (-160 +- 21 (stat.) +- 17 (syst.)) parts per
billion, with a significance of 6.3sigma for observing parity violation. In the
context of the Standard Model, this yields a measurement of the weak mixing
angle, sin^2(thetaW-MSBAR)(Q^2 = 0.026 GeV^2) = 0.2379 +- 0.0016 (stat.) +-
0.0013 (syst.). We also present preliminary results for the first observation
of a single-spin transverse asymmetry in Moller scattering.


title:
Evidence for a narrow resonance at 1530 MeV/c2 in the K0 p - system of
  the reaction pp --> Sigma+ K0 p from the COSY-TOF experiment

abstract:
  The hadronic reaction pp --> Sigma+ K0 p was measured exclusively at a beam
momentum of 2.95 GeV/c using the TOF detector at the COSY storage ring. A
narrow peak was observed in the invariant mass spectrum of the K0 p subsystem
at 1530 +- 5 MeV/c2 with a significance of 4 - 6 standard deviations, depending
on background assumptions. The upper limit of 18 +- 4 MeV/c2 (FWHM) for its
width is given by the experimental resolution. The corresponding total cross
section is estimated to be about 0.4 +- 0.1(stat) +- 0.1(syst) microbarn. Since
a resonance in this subsystem must have strangeness S = + 1 we claim it to be
the Theta+ state for which very recently evidence was found in various
experiments.


title: STAR Results from Polarized Proton Collisions at RHIC

abstract:
  This talk reports on progress from the first two years of polarized proton
collisions at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National
Laboratory (BNL). STAR is one of the two large experiments at RHIC. It features
large acceptance spanning a broad range of rapidity. The long-term goals of the
STAR spin program are to measure the gluon contribution to the proton's spin;
determine the contribution of specific quark flavors to the spin of the proton
through the study of spin observables for vector boson production, and to
determine the transversity structure function. The study of polarized proton
collisions at $\sqrt{s}$=200 and 500 GeV is expected to provide important
insight into the spin structure of the proton, revealing the contributions to
the spin sum rule either from gluons or from the orbital motion of the partons.
Selected STAR results from the study of polarized proton collisions during the
first two runs are presented.


title: A review of searches for R-parity-violating SUSY

abstract:
  Searches for pair and single production of supersymmetric particles under the
assumption that R-parity is violated via a single dominant coupling are
presented. A subset of the most recent results from LEP, Tevatron and HERA is
selected. The data are in agreement with the Standard Model expectation. Limits
on the production cross sections and the masses of supersymmetric particles are
derived.


title:
Di-Jet Production in Photon-Photon Collisions at sqrt(s_ee) = 189 to 209
  GeV

abstract:
  Di-jet production is studied in collisions of quasi-real photons at e+e-
centre-of-mass energies from 189 to 209 GeV at LEP. The data were collected
with the OPAL detector. The structure of jets is investigated and differential
cross sections are measured and compared to QCD calculations.


title: Jet production in two-photon collisions at LEP

abstract:
  Jet and di-jet production are studied in collisions of quasi-real photons
collected during the LEP2 program at e+e- center-of-mass energies from 189 to
209 GeV. OPAL reports good agreement of NLO perturbative QCD with the measured
differential di-jet cross sections, which reach a mean transverse energy of the
di-jet system of 25 GeV. L3, on the other hand, finds drastic disagreement of
the same calculation with single jet production for transverse jet momenta
larger than about 25 GeV.


title: Sigma(1385) Resonance Studies with STAR at sqrt{s_{NN}}=200 GeV

abstract:
  In p+p, d+Au, and Au+Au collisions at \sqrt{s_{NN}}=200 GeV with the STAR
detector at RHIC, \Sigma(1385)\to\Lambda+\pi were measured using two
techniques; three-particle mixing and a hybrid mixing technique. We present
results from both of these methods and compare the invariant mass spectra and
the backgrounds.


title: Evidence for a Narrow Anti-Charmed Baryon State

abstract:
  A narrow resonance in D*- p and D*+ pbar invariant mass combinations is
observed in inelastic electron-proton collisions at centre-of-mass energies of
300 GeV and 320 GeV at HERA. The resonance has a mass of 3099 \pm 3 (stat.) \pm
5 (syst.) MeV and a measured Gaussian width of 12 \pm 3 (stat.) MeV, compatible
with the experimental resolution. The resonance is interpreted as an
anti-charmed baryon with a minimal constituent quark composition of uuddcbar,
together with the charge conjugate.


title:
Identified high pT particle correlation studies in central Au + Au
  collisions at sqrt(s) = 200 GeV

abstract:
  We present azimuthal two particle correlations of high pt strange baryons and
mesons with charged hadrons in Au+Au collisions at sqrt(s) =200 A GeV. We
observe the suppression of the back to back correlations similar to the
previous measurement of azimuthal correlations of unidentified charged hadrons
in the central Au+Au collisions. The dependence of the suppression on the
leading particle transverse momentum is presented. We find that Lambda and
Anti-Lambda correlations with charged hadrons have different leading hadron pT
dependencies for same side correlations, which could indicate different
fragmentation functions for gluon and quark jets or non fragmentation
mechanisms for particle production. In addition we show that the back-to-back
correlation structure for charged hadron pairs with a high pT trigger (pT<8
GeV) is consistent with statistical momentum conservation, with no evidence of
additional jet-like correlations. This is a summary of a poster presented at
Quark Matter 2004.


title: Detectors for New Neutrino Experiments

abstract:
  There has been great progress in understanding the neutrino sector in the
last few years. One mixing angle has not yet been measured, theta-13. Detectors
for the current round of long-baseline neutrino oscillation experiments, for
future long-baseline off-axis detectors, and for two detector experiments at
nuclear reactors are reviewed.


title: Search for Theta^+ and Xi^{--}_{3/2} pentaquarks in HERA-B

abstract:
  A search for Theta^+(1540) and Xi^{--}_{3/2}(1862) pentaquark candidates has
been performed in proton-induced reactions on C, Ti and W targets at sqrt(s) =
41.6 GeV studying the pK_s resp. Xi^-pi^- and Xi^-pi^+ (and charge conjugated)
decay channels at mid-rapidity. With sensitivities of (Br)x(dsigma/dx_F) < 5 to
25 microbarn/nucleon, we find no evidence for narrow pentaquark peaks in any of
the studied final states. Preliminary values for the upper limit of relative
yield ratios at mid-rapidity are (Theta^+(1540)) / (Lambda(1520)) < 0.02,
(Br)x(Xi^{--}_{3/2}(1862)) / (Xi(1530)^0) < 0.077, and
(Br)x(Xi_bar^{++}_{3/2}(1862)) / (Xi_bar(1530)^0) < 0.058 at 95% CL.


title: Investigation of top mass measurements with the ATLAS detector at LHC

abstract:
  Several methods for the determination of the mass of the top quark with the
ATLAS detector at the LHC are presented. All dominant decay channels of the top
quark can be explored. The measurements are in most cases dominated by
systematic uncertainties. New methods have been developed to control those
related to the detector. The results indicate that a total error on the top
mass at the level of 1 GeV should be achievable.


title:
Neutral B Flavor Tagging for the Measurement of Mixing-induced CP
  Violation at Belle

abstract:
  We describe a flavor tagging algorithm used in measurements of the CP
violation parameter sin2phi_1 at the Belle experiment. Efficiencies and wrong
tag fractions are evaluated using flavor-specific B meson decays into hadronic
and semileptonic modes. We achieve a total effective efficiency of $ 28.8 +-
0.6 %.


title: \psi(2S) Decays into $\J$ plus Two Photons

abstract:
  Using $\gamma \gamma J/\psi, J/\psi \ra e^+ e^-$ and $\mu^+ \mu^-$ events
from a sample of $14.0\times 10^6$ $\psip$ decays collected with the BESII
detector, the branching fractions for $\psip\ra \pi^0\J$, $\eta\J$, and
$\psi(2S)\ar\gamma\chi_{c1},\gamma\chi_{c2}\ar\gamma\gamma\jpsi$ are measured
to be $B(\psip\ra \pi^0\J) = (1.43\pm0.14\pm0.13)\times 10^{-3}$, $B(\psip\ra
\eta\J) = (2.98\pm0.09\pm0.23)%$,
$B(\psi(2S)\ar\gamma\chi_{c1}\ar\gamma\gamma\jpsi) = (2.81\pm0.05\pm 0.23)%$,
and $B(\psi(2S)\ar\gamma\chi_{c2}\ar\gamma\gamma\jpsi) = (1.62\pm0.04\pm
0.12)%$.


title:
On the Possibilities of Measuring the Gluon Distribution Using
  'photon/Z^0+jet' Events at Tevatron Run II and LHC

abstract:
  The number of photon+jet and Z+jet events suitable for a determination of
gluon distribution function in a proton at Tevatron Run II and during the low
luminosity runs at future LHC experiments are estimated for various intervals
of x and Q^2. These numbers allow to extract gluon distribution in new
kinematic regions of 2 * 10^{-3} < x < 1.0 with 1.6*10^3 < Q^2 < 2*10^4
\~(GeV/c)^2 at Tevatron and of 2* 10^{-4} < x < 1.0$ with 1.6*10^3 < Q^2 <
2*10^5 ~(GeV/c)^2 at LHC. The contributions of background events in different
Q^2 intervals are also given.


title: B Meson Decays to eta(')K*, eta(')rho,eta(')pi0, omegapi0, and phipi0

abstract:
  We present measurements of the branching fractions and charge asymmetries
(where appropriate) of two-body B decays to eta(')K*, eta(')rho, eta(')pi0,
omegapi0, and phipi0. The data were recorded with the BABAR detector at PEP-II
and correspond to 89x10^6 BB pairs produced in e+e- annihilation through the
Upsilon(4S) resonance. We find significant signals for two decay modes and
measure the branching fractions BR(B+->etaK*+)=(25.6+/-4.0+/-2.4)x10^{-6} and
BR(B0->etaK*0)=(18.6+/-2.3+/-1.2)x10^{-6}, where the first error is statistical
and the second systematic. We also find evidence with significance 3.5sigma for
a third decay mode and measure BR(B+->etarho+)= (9.2+/-3.4+/-1.0)x10^{-6}. For
other channels, we set 90% C.L. upper limits of BR(B0->etarho0)<1.5x10^{-6},
BR(B+->eta'K*+) < 14x10^{-6}, BR(B0->eta'K*0) < 7.6x10^{-6}, BR(B+->eta'rho+) <
22x10^{-6}, BR(B0->eta'rho0) < 4.3x10^{-6}, BR(B0->etapi0) < 2.5x10^{-6},
BR(B0->eta'pi0) < 3.7x10^{-6}, BR(B0->omegapi0) < 1.2x10^{-6}, and
BR(B0->phipi0) < 1.0x10^{-6}. For self-flavor-tagging modes with significant
signals, the time-integrated charge asymmetries are
A_ch(B+->etaK*+)=+0.13\pm0.14\pm0.02 and A_ch(B0->etaK*0)=+0.02\pm0.11\pm0.02.


title:
Measurement of the Time-Dependent CP Asymmetry in the B0 --> Phi K0
  Decay

abstract:
  We present a measurement of the time-dependent CP asymmetry for the neutral
B-meson decay B0 --> Phi K0. We use a sample of approximately 114 million
B-meson pairs taken at the Upsilon(4S) resonance with the BaBar detector at the
PEP-II B-meson Factory at SLAC. We reconstruct the CP eigenstates Phi K0_S and
Phi K0_L where Phi --> K+ K-, K0_S --> pi+ pi-, and K0_L is observed via its
hadronic interactions. The other B meson in the event is tagged as either a B0
or B0-bar from its decay products. The values of the CP-violation parameters
are S = 0.47 +/- 0.34 (stat) +0.08/-0.06 (syst) and C = 0.01 +/- 0.33 (stat)
+/- 0.10 (syst).


title: Search for Squark Production in R-Parity Violating Supersymmetry at HERA

abstract:
  A search for squarks in R-parity violating supersymmetry is performed in e+/-
p collisions at HERA using the H1 detector. The data were taken at a
centre-of-mass energy of 319 GeV and correspond to an integrated luminosity of
64.3 pb-1 for e+p collisions and 13.5 pb-1 for e-p collisions. The resonant
production of squarks via a Yukawa coupling lambda' is considered, taking into
account direct and indirect R-parity violating decay modes. No evidence for
squark production is found in the multi-lepton and multi-jet final state
topologies investigated. Mass dependent limits on lambda' are obtained in the
framework of the Minimal Supersymmetric Standard Model. In addition, the
results are interpreted in terms of constraints on the parameters of the
minimal Supergravity model. At the 95% confidence level squarks of all flavours
with masses up to 275 GeV are excluded in a large part of the parameter space
for a Yukawa coupling of electromagnetic strength. For a coupling strength 100
times smaller, masses up to 220 GeV can be ruled out.


title:
On the application of Z^0+jet events for determining the gluon
  distribution in a proton at the LHC

abstract:
  It is shown that the samples of Z0+jet events, collected at the LHC with the
integrated luminosity L_{int}=20 fb^{-1}, may have enough statistics for
determining the gluon distribution inside a proton in the region of 2*10^{-4} <
x < 1.0 at Q^2 values in the interval of 0.9*10^3 < Q^2 < 4*10^4 ~(GeV/c)^2. A
possibility of the background events suppression by use of the Z^0+jet events
selection criteria is also demonstrated.


title:
Higgs pair production at a linear e+e- collider in models with large
  extra dimensions

abstract:
  In this paper, we will derive the cross section formula for the Higgs pair
production at a linear $e^+e^-$ collider in models with large extra dimensions
and study the feasibility of its measurement through realistic Monte Carlo
simulations. Since the process has essentially no Standard Model background,
once produced, it will provide us with a very clean signature of physics beyond
the Standard Model. Moreover, since the final state particles are spinless, the
spin 2 of the intermediate virtual KK gravitons has to be conserved by the
orbital angular momentum of the Higgs pair. This results in a very
characteristic angular distribution of the final states. Taking into account
finite detector acceptance and resolutions as well as initial state radiation
and beamstrahlung, we demonstrate in this paper that, given a sufficiently high
center of mass energy, the angular distribution of the Higgs pair is indeed
measurable at the linear collider and will allow us to prove the spin 2 nature
of the KK gravitons exchanged in the s-channel.

Measurement of the Electron Energy Spectrum and its Moments in Inclusive
  B->X e nu Decays

abstract:
  We report a measurement of the inclusive electron energy spectrum for
semileptonic decays of B mesons in a data sample of 52 million Y4S -> BBar
decays collected with the BABAR detector at the PEP-II asymmetric-energy
B-meson factory at SLAC. We determine the branching fraction, first, second,
and third moments of the spectrum for lower cut-offs on the electron energy
between 0.6 and 1.5 GeV. We measure the partial branching fraction to be Br(B
-> X e nu, E_e>0.6 GeV) = (10.36 +-0.06(stat.) +-0.23(sys))%.


title:
Measurements of Moments of the Hadronic Mass Distribution in
  Semileptonic B Decays

abstract:
  We report a measurement of the first four moments of the hadronic mass
distribution in B --> X_c lv decays. The measurements are based on 89 million
Upsilon(4S) --> BBbar events where the hadronic decay of one of the B mesons is
fully reconstructed and a charged lepton from the decay of the other B meson is
identified. The moments are presented for minimum lepton momenta ranging from
0.9 to 1.6 GeV in the B rest frame. It is expected that such measurements will
lead to improved determinations of |V_{cb}| and |V_{ub}|.


title:
Search for Bs->mu+mu- and Bd->mu+mu- Decays in ppbar Collisions at
  sqrt(s)=1.96 TeV

abstract:
  We report on a search for Bs->mu+mu- and Bd->mu+mu- decays in ppbar
collisions at sqrt(s)=1.96 TeV using 171 pb-1 of data collected by the CDF II
experiment at the Fermilab Tevatron Collider. The decay rates of these rare
processes are sensitive to contributions from physics beyond the Standard
Model. One event survives all our selection requirements,consistent with the
background expectation. We derive branching ratio limits of BR(Bs->mu+mu-) <
5.8 x 10^-7 and BR(Bd->mu+mu-) < 1.5 x 10^-7 at 90% confidence level.


title:
Measurement of the Branching Fractions for $B \to \omega K$ and $B \to
  \omega \pi$

abstract:
  We report improved measurements of branching fractions for charmless hadronic
two-body {\it B} meson decays containing an $\omega$ meson in the final state.
The results are based on a data sample of 78 fb$^{-1}$ collected on the
$\Upsilon(4S)$ resonance by the Belle detector. We measure the branching
fractions ${\mathcal B}(B^+ \to \omega K^+) = (6.5^{+1.3}_{-1.2}\pm 0.6)\times
10^{-6}$ and ${\mathcal B}(B^+ \to \omega \pi^+) = (5.7^{+1.4}_{-1.3}\pm
0.6)\times 10^{-6}.$ We give 90% confidence upper limits for ${\mathcal B}(B^0
\to \omega K^0) < 7.6\times 10^{-6}$ and ${\mathcal B}(B^0 \to \omega \pi^0) <
1.9\times 10^{-6}.$ We also obtain the partial rate asymmetries ${\mathcal
A}_{CP}=0.06^{+0.21}_{-0.18}\pm 0.01$ for $B^\pm \to \omega K^\pm$ and
${\mathcal A}_{CP}=0.50^{+0.23}_{-0.20}\pm 0.02$ for $B^\pm \to \omega
\pi^\pm.$


title:
Further search for the decay $K^+ \to \pi^+ \nu \bar \nu$ in the
  momentum region P < 195 MeV/c

abstract:
  We report the results of a search for the decay $K^+ \to \pi^+ \nu \bar \nu$
in the kinematic region with $\pi^+$ momentum $140 < P < 195$ MeV/c using the
data collected by the E787 experiment at BNL. No events were observed. When
combined with our previous search in this region, one candidate event with an
expected background of $1.22 \pm 0.24$ events results in a 90% C.L. upper limit
of $2.2 \times 10^{-9}$ on the branching ratio of $K^+ \to \pi^+ \nu \bar \nu$.
We also report improved limits on the rates of $K^+ \to \pi^+ X^0$ and $K^+ \to
\pi^+ X^1 X^2$ where $X^0, X^1, X^2$ are hypothetical, massless, long-lived
neutral particles.


title: Measurement of the Direct CP Asymmetry in b -> s gamma Decays

abstract:
  We describe a measurement of the direct CP asymmetry between inclusive b -> s
gamma and bbar -> sbar gamma decays. This asymmetry is expected to be less than
0.01 in the Standard Model, but could be enhanced up to about 0.10 by new
physics contributions. We use a sample of 89 million BB pairs recorded with the
BaBar detector at PEP-II, from which we reconstruct a set of 12 exclusive b ->
s gamma final states containing one charged or neutral kaon and one to three
pions. We measure an asymmetry of A_CP(b -> s gamma) = 0.025 +/- 0.050(stat.)
+/- 0.015(syst.), corresponding to an allowed range of -0.06 < A_CP(b -> s
gamma) < +0.11 at 90% confidence level.


title: Improved Measurement of the K+ to pi+ nu nubar Branching Ratio

abstract:
  An additional event near the upper kinematic limit for K+ to pi+ nu nubar has
been observed by Experiment E949 at Brookhaven National Laboratory. Combining
previously reported and new data, the branching ratio is B(K+ to pi+ nu nubar)=
1.47 (+1.30, - 0.89) x 10-10 based on three events observed in the pion
momentum region 211<P<229 MeV/c. At the measured central value of the branching
ratio, the additional event had a signal-to-background ratio of 0.9.


title: Search for Anomalous Couplings in the Higgs Sector at LEP

abstract:
  Anomalous couplings of the Higgs boson are searched for through the processes
e^+ e^- -> H gamma, e^+ e^- -> e^+ e^- H and e^+ e^- -> HZ. The mass range 70
GeV < m_H < 190 GeV is explored using 602 pb^-1 of integrated luminosity
collected with the L3 detector at LEP at centre-of-mass energies
sqrt(s)=189-209 GeV. The Higgs decay channels H -> ffbar, H -> gamma gamma, H
-> Z\gamma and H -> WW^(*) are considered and no evidence is found for
anomalous Higgs production or decay. Limits on the anomalous couplings d, db,
Delta(g1z), Delta(kappa_gamma) and xi^2 are derived as well as limits on the H
-> gamma gamma and H -> Z gamma decay rates.


title:
PHENIX measurement of jet properties and their modification in heavy-ion
  collisions

abstract:
  The properties of jets produced in p+p, d+Au and Au+Au collisions at
sqrt{s_NN}=200 GeV are studied using the method of two particle correlations.
The trigger particle is assumed to be a leading particle from a high p_T jet
while the associated particle is assumed to come from either the same jet or
the away jet. From the angular width and yield of the same and away side
correlation peaks, the parameters characterizing the jet properties are
extracted.


title: Search for neutrinoless decays tau -> 3l

abstract:
  We have searched for neutrinoless tau lepton decays into three charged
leptons using an 87.1 fb^{-1} data sample collected with the Belle detector at
the KEKB e^+e^- collider. Since the number of signal candidate events is
compatible with that expected from the background, we set 90% confidence level
upper limits on the branching fractions in the range (1.9-3.5) x 10^{-7} for
various decay modes tau -> l l l where l represents e or mu.


title: Measurement of the Lambda_b^0 Decay Form Factor

abstract:
  The form factor of Lambda_b^0 baryons is estimated using 3.46 10^6 hadronic Z
decays collected by the DELPHI experiment between 1992 and 1995. Charmed
Lambda_c^+ baryons fully reconstructed in the pK-pi+, pK0_S, and Lambda
pi+pi+pi- modes, are associated to a lepton with opposite charge in order to
select Lambda_b^0 -> Lambda_c^+ l^- anti-nu_l decays. From a combined
likelihood and event rate fit to the distribution of the Isgur-Wise variable w,
and using the Heavy Quark Effective Theory (HQET), the slope of the b-baryon
form factor is measured to be: rho-hat^2 = 2.03 +/- 0.46 (stat)
^{+0.72}_{-1.00} (syst). The exclusive semileptonic branching fraction
Br(Lambda_b^0 -> Lambda_c^+ l^- anti-nu_l) can be derived from rho-hat^2 and is
found to be (5.0^{+1.1}_{-0.8} (stat) ^{+1.6}_{-1.2} (syst))%. Limits on other
branching fractions are also obtained.


title:
Measurement of the Forward-Backward Asymmetries of e+e- -> Z -> b bbar
  and e+e- -> Z -> c cbar using prompt leptons

abstract:
  The forward-backward asymmetries of the processes e+e- -> Z -> b bbar and
e+e- -> Z -> c cbar were measured from a sample of hadronic Z decays collected
by the DELPHI experiment between 1993 and 1995. Enriched samples of b bbar and
c cbar events were obtained using lifetime information. The tagging of b and c
quarks in these samples was based on the semileptonic decay channels b/c -> X +
mu and b/c -> X + e combined with charge flow information from the hemisphere
opposite to the lepton. Combining the A_{FB}^{b bbar} and A_{FB}^{c cbar}
measurements presented in this paper with published results based on 1991 and
1992 DELPHI data samples, the following pole asymmetries were obtained:
  A_{FB}^{0,b} = 0.1021 +/- 0.0052 (stat) +/- 0.0024 (syst)
  A_{FB}^{0,c} = 0.0728 +/- 0.0086 (stat) +/- 0.0063 (syst)
  The effective value of the weak mixing angle derived from these measurements
is sin^2 theta_{W,eff}^{lept} = 0.23170 +/- 0.00097 .


title:
Measurement of the W-pair Production Cross-section and W Branching
  Ratios in e+e- Collisions at sqrt(s) = 161-209 GeV

abstract:
  These final results on e+e- -> W+W- production cross-section measurements at
LEP2 use data collected by the DELPHI detector at centre-of-mass energies up to
209 GeV. Measurements of total cross-sections, W angular differential
distributions and decay branching fractions, and the value of the CKM element
|V_{cs}| are compared to the expectations of the Standard Model.
  These results supersede all values previously published by DELPHI.


title: Quarkonia production with the Hera-B experiment

abstract:
  Measurements of the dependence of the J/Psi production cross section on its
kinematic variables as well as on the target atomic numbers for 920 GeV/c
protons incident on different targets have been made with the Hera-B detector.
The large collected di-lepton sample allows to study the production ratio of
Psi(2S) to J/Psi and of Chic to J/Psi . We also report on measurements of the
b-bbar and Upsilon production cross section.


title:
Observation of S=+1 narrow resonances in the system $K^0_sp$ from
  p+$C_3H_8$ collision at 10 GeV/c

abstract:
  The 2m propane bubble chamber experimental data have been analyzed to search
for an exotic baryon state, the $\Theta^+$ -baryon, in the $pK^0_s$ decay mode
for the reaction p+$C_3H_8$ at 10 GeV/c. The $pK^0_s$ invariant mass spectrum
shows resonant structures with $M_{K_s^0 p}$=1540$\pm$8, 1613$\pm$10,
1821$\pm$11 MeV/$c^2$ and $\Gamma_{K_s^0 p}$= 9.2$\pm$1.8, 16.1$\pm$4.1,
28.0$\pm$9.4 MeV/$c^2$. The maximal statistical significance of these peaks
have been estimated as 5.5$\sigma$,4.8$\sigma$ and 5.0$\sigma$, respectively.


title: Search for hadronic axions using axioelectric effect

abstract:
  We made a search for hadronic axions which could be emitted from the Sun in
M1 transitions between the first 14.4 keV thermally excited and the ground
state in Fe-57, and absorbed in the HPGe detector by axioelectric effect. An
upper limit on hadronic axion mass of 400 eV is obtained at the 95% confidence
level.


title: Searches for B0 Decays to Combinations of Charmless Isoscalar Mesons

abstract:
  We search for B meson decays into two-body combinations of eta, eta', omega,
and phi mesons from 89 million B B-bar pairs collected with the BaBar detector
at the PEP-II asymmetric-energy e+e- collider at SLAC. We find the branching
fraction BF(B0 -> eta omega) = (4.0^{+1.3}_{-1.2} +- 0.4) x 10^-6 with a
significance of 4.3 sigma. For all the other decay modes we set the following
90% confidence level upper limits on the branching fractions, in units of 10^-6
: BF(B0 -> eta eta)<2.8, BF(B0 -> eta eta')<4.6, BF(B0 -> eta' eta')<10, BF(B0
-> eta'omega)<2.8, BF(B0 -> eta phi)<1.0, BF(B0 -> eta' phi)<4.5, BF(B0 -> phi
phi)<1.5.


title: Search for SUSY in the AMSB scenario with the DELPHI detector

abstract:
  The DELPHI experiment at the LEP e+e- collider collected almost 700 pb^-1 at
centre-of-mass energies above the Z0 mass pole and up to 208 GeV. Those data
were used to search for SUSY in the Anomaly Mediated SUSY Breaking (AMSB)
scenario with a flavour independent common sfermion mass parameter. The
searches covered several possible signatures experimentally accessible at LEP,
with either the neutralino, the sneutrino or the stau being the Lightest
Supersymmetric Particle (LSP). They included: the search for nearly
mass-degenerate chargino and neutralino, which is a typical feature of AMSB;
the search for Standard-Model-like or invisibly decaying Higgs boson; the
search for stable staus; the search for cascade decays of SUSY particles
resulting in the LSP and a low multiplicity final state containing neutrinos.
No evidence of a signal was found, and thus constraints were set in the space
of the parameters of the model.


title: Precision Measurement of sin^2 theta_W at a Reactor

abstract:
  This paper presents a strategy for measuring sin^2 theta_W to ~1% at a
reactor-based experiment, using antineutrinos electron elastic scattering. This
error is comparable to the NuTeV, SLAC E158, and APV results on sin^2 theta_W,
but with substantially different contributions to the systematics. An improved
method for identifying antineutrino proton events, which serve both as a
background and as a normalization sample, is described. The measurement can be
performed using the near detector of the presently proposed reactor-based
oscillation experiments. We conclude that an absolute error of delta(sin^2
theta_W)=0.0019 may be achieved.


title: Search for SM and MSSM Higgs Bosons at LEP

  Latest results from the LEP Collaboration on searches for neutral Higgs
bosons predicted by the Standard Model and its minimal supersymmetric
extension, the MSSM, are summarized.


title:
High energy cosmic ray particles and the most powerful new type
  discharges in thunderstorm atmosphere

abstract:
  The runaway breakdown -- extensive atmospheric shower discharge (RB - EAS)
excited in thunderstorm atmosphere by high energy cosmic ray particles
($\epsilon_p>10^{17} - 10^{19}$ eV) generate very powerful radio pulse. The RB
- EAS theory is compared with observations of radio pulses. An agreement
between the theory and experiment is established. The existence of nowaday
satellite and ground based systems which obtain regularly a large amount of
observational radio data could allow to use them in combination with other
methods for effective study of high energy cosmic ray particles


title:
Evidence for a narrow baryonic state decaying to K0s-p and K0s-pbar in
  deep inelastic scattering at HERA

abstract:
  A resonance search has been made in the K0s p and K0s pbar invariant-mass
spectrum measured with the ZEUS detector at HERA using an integrated luminosity
of 121 pb-1. The search was performed in the central rapidity region of
inclusive deep inelastic scattering at an ep centre-of-mass energy of 300-318
GeV for exchanged photon virtuality, Q2, above 1 GeV2. Recent results from
fixed-target experiments give evidence for a narrow baryon resonance decaying
to K+ n and K0s p, interpreted as a pentaquark. The results presented here
support the existence of such state, with a mass of
1521.5+/-1.5(stat.)^{+2.8}_{-1.7}(syst.) MeV and a Gaussian width consistent
with the experimental resolution of 2 MeV. The signal is visible at high Q2
and, for Q2>20 GeV2, contains 221+/-48 events. The probability of a similar
signal anywhere in the range 1500-1560 MeV arising from fluctuations of the
background is below 6x10^{-5}.


title:
Moments of the B Meson Inclusive Semileptonic Decay Rate using Neutrino
  Reconstruction

abstract:
  We present a measurement of the composition of B meson inclusive semileptonic
decays using 9.4 fb^-1 of e^+e^- data taken with the CLEO detector at the
Upsilon(4S) resonance. In addition to measuring the charged lepton kinematics,
the neutrino four-vector is inferred using the hermiticity of the detector. We
perform a maximum likelihood fit over the full three-dimensional differential
decay distribution for the fractional contributions from the B -> X_c l nu
processes with X_c = D, D*, D**, and nonresonant X_c, and the process B -> X_u
l nu. From the fit results we extract the first and second moments of the M_X^2
and q^2 distributions with minimum lepton-energy requirements of 1.0 GeV and
1.5 GeV. We find <M_X^2 - M_D[Bar]^2> = 0.456 +- 0.014 +- 0.045 +- 0.109
(GeV/c^2)^2 with a minimum lepton energy of 1.0 GeV and <M_X^2 - M_D[Bar]^2> =
0.293 +- 0.012 +- 0.033 +- 0.048 (GeV/c^2)^2 with minimum lepton energy of 1.5
GeV. The uncertainties are from statistics, detector systematic effects, and
model dependence, respectively. As a test of the HQET and OPE calculations, the
results for the M^X_c moment as a function of the minimum lepton energy
requirement are compared to the predictions.


title:
Measurement of the B-Meson Inclusive Semileptonic Branching Fraction and
  Electron-Energy Moments

abstract:
  We report a new measurement of the B-meson semileptonic decay momentum
spectrum that has been made with a sample of 9.4/fb of electron-positron
annihilation data collected with the CLEO II detector at the Y(4S) resonance.
Electrons from primary semileptonic decays and secondary charm decays were
separated by using charge and angular correlations in Y(4S) events with a
high-momentum lepton and an additional electron. We determined the semileptonic
branching fraction to be (10.91 +- 0.09 +- 0.24)% from the normalization of the
electron-energy spectrum. We also measured the moments of the electron energy
spectrum with minimum energies from 0.6 GeV to 1.5 GeV.


title:
Jets in Deep Inelastic Scattering and High Energy Photoproduction at
  HERA

abstract:
  Recent results on jet production in neutral current deep inelastic scattering
and high energy photoproduction at the HERA electron-proton-collider are
briefly reviewed. The results are compared to QCD expectations in NLO and
$\alpha_s$ determinations using these data are summarized.


title: Study of Bose-Einstein Correlations in e+e- -> W+W- events at LEP

abstract:
  Bose-Einstein correlation between like-sign charged-particle pairs in e+e- ->
W+W- events recorded with the OPAL detector at LEP at centre-of-mass energies
between 183 GeV and 209 GeV are studied. Recently proposed methods which allow
direct searches for correlations in the data via distributions of test
variables are used to investigate the presence of correlations between hadrons
originating from different W bosons in W+W- -> qqqq events. Within the
statistics of the data sample no evidence for inter-WW Bose-Einstein
correlations is obtained. The data are also compared with predictions of a
recent implementation of Bose-Einstein correlation effects in the Monte Carlo
model PYTHIA.


title:
Measurement of Anti-Deuteron Photoproduction and a Search for Heavy
  Stable Charged Particles at HERA

abstract:
  The cross section for anti-deuteron photoproduction is measured at HERA at a
mean centre-of-mass energy of W_{\gamma p} = 200 GeV in the range 0.2 < p_T/M <
0.7 and |y| < 0.4, where M, p_T and y are the mass, transverse momentum and
rapidity in the laboratory frame of the anti-deuteron, respectively. The
numbers of anti-deuterons per event are found to be similar in photoproduction
to those in central proton-proton collisions at the CERN ISR but much lower
than those in central Au-Au collisions at RHIC. The coalescence parameter B_2,
which characterizes the likelihood of anti-deuteron production, is measured in
photoproduction to be 0.010 \pm 0.002 \pm 0.001, which is much higher than in
Au-Au collisions at a similar nucleon-nucleon centre-of-mass energy. No
significant production of particles heavier than deuterons is observed and
upper limits are set on the photoproduction cross sections for such particles.


title: Interactions of Heavy Stable Hadronizing Particles

abstract:
  In this article, we study the interactions of stable, hadronizing new states,
arising in certain extensions of the Standard Model. A simple model, originally
intended for stable gluino hadrons, is developed to describe the nuclear
interactions of hadrons containing any new colour triplet or octet stable
parton. Hadron mass spectra, nuclear scattering cross sections and interaction
processes are discussed. Furthermore, an implementation of the interactions of
heavy hadrons in GEANT 3 is presented, signatures are studied, and a few
remarks about possible detection with the ATLAS experiment are given.


title:
Study of the pion trajectory in the photoproduction of leading neutrons
  at HERA

abstract:
  Energetic neutrons produced in $ep$ collisions at HERA have been studied with
the ZEUS detector in the photoproduction regime at a mean photon-proton
center-of-mass energy of 220 GeV. The neutrons carry a large fraction $0.64 <
x_L <0.925$ of the incoming proton energy, and the four-momentum-transfer
squared at the proton-neutron vertex is small, $|t|<0.425$ GeV$^2$. The $x_L$
distribution of the neutrons is measured in bins of $t$. The $(1-x_L)$
distributions in the $t$ bins studied satisfy a power law $dN/dx_L \propto
(1-x_L)^{a(t)}$, with the powers $a(t)$ following a linear function of $t$:
\mbox{$a(t)=0.88\pm 0.09 ({\rm stat.})^{+0.34}_{-0.39}({\rm syst.})-(2.81\pm
0.42({\rm stat.})^{+1.13}_{-0.62}({\rm syst.}) {\rm Ge V}^{-2})t$.} This result
is consistent with the expectations of pion-exchange models, in which the
incoming proton fluctuates to a neutron-pion state, and the electron interacts
with the pion.


title:
The Search and Study of the Baryonic Resonances with the Strangeness S =
  +1 in the System of nK+ from the Reaction np -> npK+K- at the Momentum of
  Incident Neutrons Pn = (5.20+/-0.12)GeV/c

abstract:
  The production and properties of the resonances with the strangeness S = +1
in the system of nK+ were studied in the reaction np -> npK+K- at the momentum
of incident neutrons Pn = (5.20+/-0.12)GeV/c. A number of peculiarities was
found in the effective mass spectrum of the mentioned above system. All these
resonances have a large statistical significance. Their widths are comparable
with the mass resolution. The estimation of the spins of resonances was carried
out and the rotational band connecting the resonances masses and their spins
was constructed.


title: The Underlying Event in Hard Interactions at the Tevatron pbarp Collider

abstract:
  For comparison of inclusive jet cross sections measured at hadron-hadron
colliders to next-to-leading order (NLO) parton-level calculations, the energy
deposited in the jet cone by spectator parton interactions must first be
subtracted. The assumption made at the Tevatron is that the spectator parton
interaction energy is similar to the ambient level measured in minimum bias
events. In this paper, we test this assumption by measuring the ambient charged
track momentum in events containing large transverse energy jets at
$\sqrt{s}=1800$ GeV and $\sqrt{s}=630$ GeV and comparing this ambient momentum
with that observed both in minimum bias events and with that predicted by two
Monte Carlo models. Two cones in $\eta$--$\phi$ space are defined, at the same
pseudo-rapidity, $\eta$, as the jet with the highest transverse energy
($E_T^{(1)}$), and at $\pm 90^o$ in the azimuthal direction, $\phi$. The total
charged track momentum inside each of the two cones is measured. The minimum
momentum in the two cones is almost independent of $E_T^{(1)}$ and is similar
to the momentum observed in minimum bias events, whereas the maximum momentum
increases roughly linearly with the jet $E_T^{(1)}$ over most of the measured
range. This study will help improve the precision of comparisons of jet cross
section data and NLO perturbative QCD predictions. %this is new The
distribution of the sum of the track momenta in the two cones is also examined
for five different $E_T^{(1)}$ bins. The HERWIG and PYTHIA Monte Carlos are
reasonably successful in describing the data, but neither can describe
completely all of the event properties.


title:
Measurement of the Ratio of Decay Amplitudes for B0bar -> J/psi K*0 and
  B0 -> J/psi K*0

abstract:
  We have measured the time-dependent decay rate for the process $B \to J/\psi
K^{*0}(892)$ in a sample of about 88 million $\Upsilon(4S) \to B\bar{B}$ decays
collected with the BaBar detector at the PEP-II asymmetric-energy $B$ Factory
at SLAC. In this sample we study flavor-tagged events in which one neutral $B$
meson is reconstructed in the $J/\psi K^{*0}$ or $J/\psi \bar{K}^{*0}$ final
state. We measure the coefficients of the cosine and sine terms in the
time-dependent asymmetries for $J/\psi K^{*0}$ and $J/\psi \bar{K}^{*0}$, find
them to be consistent with the Standard Model expectations, and set upper
limits at 90% C.L. on the decay amplitude ratios $|A (\bar{B}^0 \to J/\psi
K^{*0})|/|A (B^0 \to J/\psi K^{*0})| < 0.26$ and $|A (B^0 \to J/\psi
\bar{K}^{*0})|/|A (\bar{B}^0 \to J/\psi \bar{K}^{*0})| <0.32$. For a single
ratio of wrong-flavor to favored amplitudes for $B^0$ and $\bar{B}^0$ combined,
we obtain an upper limit of 0.25 at 90% C.L.

Measurement of the B -> Xs l+ l- branching fraction with a sum over
  exclusive modes

abstract:
  We measure the branching fraction for the flavor-changing neutral-current
process B -> Xs l+ l- with a sample of 89 x 10^6 Upsilon(4S) -> BBbar events
recorded with the BaBar detector at the PEP-II e+e- storage ring. The final
state is reconstructed from e+e- or mu+mu- pairs and a hadronic system
consisting of one K or K0s and up to two pions, with at most one pi0. We
observe a signal of 40 +/- 10(stat) +/- 2(syst) events and extract the
inclusive branching fraction B(B -> Xs l+ l-) =
  (5.6 +/- 1.5(stat) +/- 0.6(exp syst) +/- 1.1(model syst)) x 10^-6 for mll >
0.2 GeV/c^2.


title: Observation of a narrow baryonic state in DIS at HERA

abstract:
  A resonance search has been made in the K^{0}s-p, K^{0}s-pbar and K^{+}p
invariant-mass spectra measured with the ZEUS detector at HERA using an
integrated luminosity of 121 pb^{-1}. The search was performed in the central
rapidity region of inclusive deep inelastic scattering at an ep centre-of-mass
energy of 300--318 GeV for exchanged photon virtuality, Q2, above 1 GeV^{2}.
The results support the existence of a narrow state in K^{0}s-p and K^{0}s-pbar
decay channels, consistent with the pentaquark prediction. No signal was found
in the K^{+}p$ decay channel.


title: Exclusive electroproduction of J/psi mesons at HERA

abstract:
  The exclusive electroproduction of J/psi mesons, ep->epJ/psi, has been
studied with the ZEUS detector at HERA for virtualities of the exchanged photon
in the ranges 0.15<Q^2<0.8 GeV^2 and 2<Q^2<100 GeV^2 using integrated
luminosities of 69 pb^-1 and 83 pb^-1, respectively.The photon-proton
centre-of-mass energy was in the range 30<W<220 GeV and the squared
four-momentum transfer at the proton vertex |t|<1.The cross sections and decay
angular distributions are presented as functions of Q^2, W and t. The effective
parameters of the Pomeron trajectory are in agreement with those found in J/psi
photoproduction. The spin-density matrix elements, calculated from the decay
angular distributions, are consistent with the hypothesis of s-channel helicity
conservation. The ratio of the longitudinal to transverse cross sections,
sigma_L/sigma_T, grows with Q^2, whilst no dependence on W or t is observed.
The results are in agreement with perturbative QCD calculations and exhibit a
strong sensitivity to the gluon distribution in the proton.


title:
Forward pi^0 Production and Associated Transverse Energy Flow in
  Deep-Inelastic Scattering at HERA

abstract:
  Deep-inelastic positron-proton interactions at low values of Bjorken-x down
to x \approx 4.10^-5 which give rise to high transverse momentum pi^0 mesons
are studied with the H1 experiment at HERA. The inclusive cross section for
pi^0 mesons produced at small angles with respect to the proton remnant (the
forward region) is presented as a function of the transverse momentum and
energy of the pi^0 and of the four-momentum transfer Q^2 and Bjorken-x.
Measurements are also presented of the transverse energy flow in events
containing a forward pi^0 meson. Hadronic final state calculations based on QCD
models implementing different parton evolution schemes are confronted with the
data.


title: Combination of CDF and D0 Results on the Top-Quark Mass

abstract:
  The results on the measurements of the top-quark mass, based on the data
collected by the Tevatron experiments CDF and DO at Fermilab during Run I from
1992 to 1996, are summarized. The combination of the published results, taking
correlated uncertainties properly into account, is presented. The resulting
world average for the mass of the top quark is: $M_t = 178.0 \pm 4.3 GeV/c^2$,
where the total error of consists of a statistical part of $2.7 GeV/c^2$ and a
systematic part of $3.3 GeV/c^2$.


title:
Bose-Einstein Correlations in Charged Current Muon-Neutrino Interactions
  in the NOMAD Experiment at CERN

abstract:
  Bose-Einstein Correlations in one and two dimensions have been studied, with
high statistics, in charged current muon-neutrino interaction events collected
with the NOMAD detector at CERN. In one dimension the Bose-Einstein effect has
been analyzed with the Goldhaber and the Kopylov-Podgoretskii phenomenological
parametrizations. The Goldhaber parametrization gives the radius of the pion
emission region R_G = 1.01+/-0.05(stat)+0.09-0.06(sys) fm and for the
chaoticity parameter the value lambda = 0.40+/-0.03(stat)+0.01-0.06(sys). Using
the Kopylov-Podgoretskii parametrization yields R_KP =
2.07+/-0.04(stat)+0.01-0.14(sys) fm and lambda_KP =
0.29+/-0.06(stat)+0.01-0.04(sys). Different parametrizations of the long-range
correlations have been also studied. The two-dimensional shape of the source
has been investigated in the longitudinal co-moving frame. A significant
difference between the transverse and the longitudinal dimensions is observed.
The high statistics of the collected sample allowed the study of the
Bose-Einstein correlations as a function of rapidity, charged particle
multiplicity and hadronic energy. A weak dependence of both radius and
chaoticity on multiplicity and hadronic energy is found.


title:
Search for Charged Higgs Bosons at LEP in General Two Higgs Doublet
  Models

abstract:
  A search for pair-produced charged Higgs bosons was performed in the data
collected by the DELPHI detector at LEP II at centre-of-mass energies from 189
GeV to 209 GeV. Five different final states, tau+ nu_tau tau- anti-nu_tau, c
sbar cbar s, c sbar tau- anti-nu_tau, W* A W* A and W* A tau- anti-nu_tau were
considered, accounting for the major expected decays in type I and type II Two
Higgs Doublet Models. No significant excess of data compared to the expected
Standard Model processes was observed. The existence of a charged Higgs boson
with mass lower than 76.7 GeV/c^2 (type I) or 74.4 GeV/c^2 (type II) is
excluded at the 95% confidence level, for a wide range of the model parameters.
Model independent cross-section limits have also been calculated.


title:
Search for B0_s - anti-B0_s oscillations in DELPHI using high-p_t
  leptons

abstract:
  Oscillations in the B0_s - anti-B0_s system were studied in events selected
from about 4.3 million hadronic Z^0 decays registered by DELPHI between 1992
and 2000. This paper presents updates of two published analyses ([11,12]). The
first analysis, which utilizes leptons emitted with large momentum transverse
to a jet, was improved by means of a better algorithm for the vertex
reconstuction and a new algorithm for flavour-tagging at production time. The
second analysis, which utilizes D_s-lepton events, was improved by optimizing
the treatment of proper time resolution. No signal of B0_s oscillations was
observed and limits on the mass difference between the physical B0_s states
were obtained to be:
  \Delta m_s > 8.0 ps^{-1} at the 95% C.L. with a sensitivity of \Delta m_s =
9.1 ps^{-1} in the high p_t lepton analysis and \Delta m_s > 4.9 ps^{-1} at the
95% C.L. with a sensitivity of \Delta m_s = 8.6 ps^{-1} in the D_s-lepton
analysis. Previously published results on these analyses are superseed. The
combination of these results with those obtained in other independent analyses
previously performed in DELPHI (D_s-hadron, exclusive B0_s, inclusive vertex)
gives: \Delta m_s > 8.5 ps^{-1} at the 95% C.L. with a sensitivity of \Delta
m_s = 12.0 ps^{-1}.

Search for single top production via FCNC at LEP at sqrt(s) = 189-208
  GeV

abstract:
  A search for single top production (e+e- -> t cbar) via Flavour Changing
Neutral Currents (FCNC) was performed using the data taken by the DELPHI
detector at LEP2. The data analysed have been accumulated at centre-of-mass
energies ranging from 189 to 208 GeV. Limits at 95% confidence level were
obtained on the anomalous coupling parameters kappa_gamma and kappa_Z.


title:
Search for Doubly-charged Higgs Boson Pair Production in the Decay to
  mu+mu+mu-mu- in p pbar Collisions at s**1/2=1.96 TeV

abstract:
  A search for pair production of doubly-charged Higgs bosons in the process p
pbar to H++H-- to mu+mu+mu-mu- is performed with the D0 Run II detector at the
Fermilab Tevatron. The analysis is based on a sample of inclusive di-muon data
collected at an energy of sqrt{s}=1.96 TeV, corresponding to an integrated
luminosity of 113 pb-1. In the absence of a signal, 95 % confidence level mass
limits of M(H++L)>118.4 GeV/c2 and M(H++R)>98.2 GeV/c2 are set for left-handed
and right-handed doubly-charged Higgs bosons, respectively, assuming 100%
branching into muon pairs.


title: Evidence of $\sigma$ particle in $J/\psi \to \omega \pi \pi$

abstract:
  Based on a sample of 7.8 million BESI $J/\psi$ events, the decay of $ J/\psi
\to \omega \pi^+ \pi^-$ is studied. A low mass enhancement in the $\pi^+ \pi^-$
invariant mass spectrum recoiling against $\omega$ particle is clearly seen
which does not come from the phase space effect and the background. According
to PWA analysis, this low mass enhancement is a broad $0^{++}$ resonance, the
$\sigma$ particle. If a Breit-Winger function of constant width is used to fit
the $\sigma$ signal, its mass and width are $384 \pm 66$ MeV and $458 \pm 100$
MeV respectively, which correspond to the pole position at (434 $\pm$ 78) - $i$
(202 $\pm$ 43) MeV.


title:
Determination of the Branching Fraction for B --> Xc l nu Decays and of
  |Vcb| from Hadronic-Mass and Lepton-Energy Moments

abstract:
  We determine the inclusive B --> Xc l nu branching fraction, the CKM matrix
element |Vcb|, and other heavy-quark parameters from a simultaneous fit to
moments of the hadronic-mass and lepton-energy distributions in semileptonic
B-meson decays, measured as a function of the lower limit on the lepton energy,
using data recorded with the BABAR detector. Using Heavy Quark Expansions
(HQEs) to order 1/mb^3, we extract BR_cenu=(10.61 +- 0.16(exp) +- 0.06(HQE))%
and |Vcb| = (41.4 +- 0.4(exp) +- 0.4(HQE) +- 0.6(th)) 10^-3. The stated errors
refer to the experimental, HQE, and additional theoretical uncertainties.


title:
Search for the Lepton-Flavor-Violating Decay $\tau^- \to \mu^- \eta$ at
  Belle

abstract:
  We have searched for the Lepton Flavor Violating decay $\tau^- \to \mu^-
\eta$ using a data sample of 84.3 fb$^{-1}$ accumulated with the Belle detector
at KEK. The $\eta$-meson was detected through the decay modes: $\eta \to
\gamma\gamma$ and $\pi^+\pi^-\pi^0$. No signal candidates are found, and we
obtain an upper limit for the branching fraction ${\cal B}(\tau^- \to \mu^-
\eta)<3.4\times 10^{-7}$ at the 90% confidence level.


title:
Total Cross Section of the Process e+e- -> pi+pi-pi+pi- in the
  C.M.Energy Range 980-1380 MeV

abstract:
  The e+e- -> pi+pi-pi+pi- cross section has been measured using 5.8/pb of
integrated luminosity collected with the CMD-2 detector at the VEPP-2M
collider. Analysis of the data with a refined efficiency determination and use
of both three- and four-track events allowed doubling of a data sample and
reduction of systematic errors to 5-7%.


title: Study of psi(2S) decays to X J/psi

abstract:
  Using J/psi -> mu^+ mu^- decays from a sample of approximately 4 million
psi(2S) events collected with the BESI detector, the branching fractions of
psi(2S) -> eta J/psi, pi^0 pi^0 J/psi, and anything J/psi normalized to that of
psi(2S) -> pi^+ pi^- J/psi are measured. The results are B(psi(2S) -> eta
J/psi)/B(psi(2S) -> pi^+ pi^- J/psi) = 0.098 \pm 0.005 \pm 0.010, B(psi(2S) ->
pi^0 pi^0 J/psi)/B(psi(2S) -> pi^+ pi^- J/psi) = 0.570 \pm 0.009 \pm 0.026, and
B(psi(2S) -> anything J/psi)/B(psi(2S) -> pi^+ pi^- J/psi) = 1.867 \pm 0.026
\pm 0.055.


title: First Observation of a Upsilon(1D) State

abstract:
  We present the first evidence for the production of Upsilon(1D) states in the
four-photon cascade, Upsilon(3S)-->gamma chib(2P), chib(2P)-->gamma
Upsilon(1D), Upsilon(1D)-->gamma chib(1P), chib(1P)-->gamma Upsilon(1S),
followed by the Upsilon(1S) annihilation into e+e- or mu+mu-. The signal has a
significance of 10.2 standard deviations. The measured product branching ratio
for these five decays, (2.5+-0.5+-0.5)x10^(-5), is consistent with the
theoretical estimates. The data are dominated by the production of one
Upsilon(1D) state consistent with the J=2 assignment. Its mass is determined to
be (10161.1+-0.6+-1.6) MeV, which is consistent with the predictions from
potential models and lattice QCD calculations.
  We also searched for Upsilon(3S)-->gammachib(2P),
chib(2P)-->gammaUpsilon(1D), followed by either Upsilon(1D)-->eta Upsilon(1S)
or Upsilon(1D)-->pi+pi- Upsilon(1S). We find no evidence for such decays and
set upper limits on the product branching ratios.


title: Direct photon cross section with conversions at CDF

abstract:
  We present a measurement of the isolated direct photon cross section in
p-pbar collisions at sqrt(s) = 1.8 TeV and |eta| < 0.9 using data collected
between 1994 and 1995 by the Collider Detector at Fermilab (CDF). The
measurement is based on events where the photon converts into an
electron-positron pair in the material of the inner detector, resulting in a
two-track event signature. To remove pi0 -> gamma gamma and eta -> gamma gamma
events we use a new background subtraction technique which takes advantage of
the tracking information available in a photon conversion event. We find that
the shape of the cross section as a function of pT is poorly described by
next-to-leading-order QCD predictions, but agrees with previous CDF
measurements.


title:
Bose-Einstein Correlations in charged current muon-neutrino interactions
  in NOMAD

abstract:
  Bose-Einstein Correlations in one and two dimensions have been studied in
charged current muon-neutrino interaction events collected with NOMAD. In one
dimension the Bose-Einstein effect has been analyzed with the Goldhaber and the
Kopylov parametrizations. The two-dimensional shape of the source has been
investigated in the longitudinal co-moving frame. A significant difference
between the transverse and the longitudinal sizes is observed.


title:
Non Identical strange particle correlations in Au-Au collisions at
  $\sqrt{s_{NN}}=$ 200 GeV from the STAR experiment

abstract:
  Information about the space-time evolution of colliding nuclei can be
extracted correlating particles emitted from nuclear collisions. The high
density of particles produced in the STAR experiment allows the measurement of
non-identical strange particle correlations. Due to the absence of Coulomb
interaction, $p-\Lambda$ and $\bar{p}-\Lambda$ systems are more sensitive to
the source size than $p-p$ pairs. Strong interaction potential has been studied
using $p-\Lambda$, and for the first time, $\bar{p}-\Lambda$ pairs. The
experimental correlation functions have been described in the frame of a model
based on the $p-n$ interaction. The first preliminary measurement of $\pi$ -
$\Xi$ correlations has been performed, allowing to extract information about
the freeze-out time and the space-time asymmetries in particle emission closely
related to the transverse radial expansion and decay of resonances.


title:
Search for Dark Matter WIMPs using Upward Through-going Muons in
  Super-Kamiokande

abstract:
  We present the results of indirect searches for Weakly Interacting Massive
Particles (WIMPs) with 1679.6 live days of data from the Super-Kamiokande
detector using neutrino-induced upward through-going muons. The search is
performed by looking for an excess of high energy muon neutrinos from WIMP
annihilations in the Sun, the core of the Earth, and the Galactic Center, as
compared to the number expected from the atmospheric neutrino background. No
statistically significant excess was seen. We calculate flux limits in various
angular cones around each of the above celestial objects. We obtain
conservative model-independent upper limits on WIMP-nucleon cross-section as a
function of WIMP mass and compare these results with the corresponding results
from direct dark matter detection experiments.
