  gamma

abstract:
  We present a measurement of the partial branching fractions and mass spectra
of the exclusive radiative penguin processes B -> K pi pi gamma in the range
m_Kpipi < 1.8 GeV/c^2. We reconstruct four final states: K+ pi- pi+ gamma, K+
pi- pi0 gamma, Ks pi- pi+ gamma, and Ks pi+ pi- gamma, where Ks -> pi+ pi-.
Using 232 million e+ e- -> B Bbar events recorded by the BaBar experiment at
the PEP-II asymmetric-energy storage ring, we measure the branching fractions
  BR(B+ -> K+ pi- pi+ gamma) = (2.95 +- 0.13 (stat.) +- 0.20 (syst.)) x 10^-5,
  BR(B0 -> K+ pi- pi0 gamma) = (4.07 +- 0.22 (stat.) +- 0.31 (syst.)) x 10^-5,
  BR(B0 -> K0 pi+ pi- gamma) = (1.85 +- 0.21 (stat.) +- 0.12 (syst.)) x 10^-5,
and BR(B+ -> K0 pi+ pi0 gamma) = (4.56 +- 0.42 (stat.) +- 0.31 (syst.)) x
10^-5.

Impact of future HERA data on the determination of proton parton
  distribution functions using the ZEUS QCD fit

abstract:
  The high precision and large kinematic coverage of the data from the HERA-I
running period (1994-2000) have already allowed precise extractions of proton
parton distribution functions (PDFs). The HERA-II running program is now
underway and is expected to provide a substantial increase in the luminosity
collected at HERA. In this paper, a study is presented which investigates the
potential impact of future data from HERA on the proton PDF uncertainties,
within the currently planned running scenario. In addition, the effect of a
possible future measurement of the longitudinal structure function, FL, on the
gluon distribution is investigated.

Observation of a chi_{c2}' candidate in gamma gamma-->D Dbar production
  in Belle

abstract:
  We report on a search for the production of new resonance states in the
process gamma gamma-->D Dbar. A candidate C-even charmonium state is observed
in the vicinity of 3.93 GeV/c^2. The production rate and the angular
distribution in the gamma gamma center-of-mass frame suggest that this state is
the previously unobserved chi_{c2}', the 2 ^3P_2 charmonium state.


title:
Search for B -> tau nu and B -> K nu nubar Decays with a Fully
  Reconstructed B at Belle

abstract:
  We present a search for the decays B -> tau nu and B -> K nu nubar in a 253
fb^-1 data sample collected at the Upsilon(4S) resonance with the Belle
detector at the KEKB asymmetric energy B factory. Combinatorial and continuum
backgrounds are suppressed by selecting a sample of events with one fully
reconstructed B. The decay products of the B on the other side of the event are
analyzed to search for B -> tau nu and B -> K nu nubar decays. We find no
significant evidence for a signal and set 90% confidence level upper limits of
B(B -> tau nu) < 1.8*10^-4 and B(B -> K nu nubar) < 3.6*10^-5.


title: QCD analyses of HERA cross section data

abstract:
  The H1 and ZEUS Collaborations have performed new next-to-leading order QCD
analyses to determine the parton density functions of the proton. QCD fits are
performed using inclusive neutral and charged deep inelastic scattering cross
sections from HERA-I. The fits include a full treatment of experimental
systematic uncertainties, taking into account point-to-point correlations. The
extracted parton densities are in agreement with those from global fits. Since
HERA inclusive data provide no direct information on the high-x gluon, an
independent fit has been performed by the ZEUS Collaboration in which the
inclusive cross sections are supplemented by jet data from neutral current deep
inelastic scattering and photoproduction. The determination of the gluon
distribution is significantly improved in such fits, allowing a competitive
extraction of the strong coupling, alpha_s(MZ).


title: Search for the decay B0 to gamma gamma

abstract:
  The rare decay B0 -> gamma gamma is searched for in 104 fb^-1 of data,
corresponding to 111 x 10^6 BBar pairs, collected with the Belle detector at
the KEKB asymmetric-energy e+ e- collider. No evidence for the signal is found,
and an upper limit of 6.2 x 10^-7 at 90% confidence level is set for the
corresponding branching fraction.


title:
Time-Dependent CP Asymmetries in b --> s qbar q Transitions and sin2phi1
  in B0 --> J/psi K0 Decays with 386 Million BBbar Pairs

abstract:
  We present measurements of time-dependent CP asymmetries in B0 --> phi(1020)
K0, eta' K0, Ks Ks Ks, Ks pi0, f0(980) Ks, omega Ks and K+ K- Ks decays based
on a sample of 386 x 10^6 BBbar pairs collected at the Upsilon(4S) resonance
with the Belle detector at the KEKB energy-asymmetric e+e- collider. These
decays are dominated by the b --> s gluonic penguin transition and are
sensitive to new CP-violating phases from physics beyond the standard model.
One neutral B meson is fully reconstructed in one of the specified decay
channels, and the flavor of the accompanying B meson is identified from its
decay products. CP-violation parameters sin2phi1^eff and {\cal A} for each of
the decay modes are obtained from the asymmetries in the distributions of the
proper-time intervals between the two B decays. We also perform an improved
measurement of CP asymmetries in B0 --> J/psi K0 decays using the same data
sample. The same analysis procedure mentioned above yields sin2phi1 = +0.652
+/- 0.039(stat) +/- 0.020(syst), which serves as a reference point for the
standard model, and {\cal A} = +0.010 +/- 0.026(stat) +/- 0.036(syst).


title:
Measurement of the time-dependent CP-violating asymmetry in $B^0 \to
  K^{0}_s\pi^0\gamma$ decays

abstract:
  We present a measurement of the time-dependent CP-violating asymmetry in $B^0
\to K^{*}_0\gamma$ decays with $K^{*}_0\to K^{0}_s\pi^0$ based on 232 million
$\Upsilon(4\mathrm{S})\to B\bar{B}$ decays collected with the BaBar detector at
the PEP-II asymmetric-energy $e^{+}e^{-}$ collider at SLAC. In a sample
containing $157\pm 16$ signal decays, we measure $S_{K^{*}_0\gamma} = -0.21 \pm
0.40 \pm 0.05$ and $C_{K^{*}_0\gamma}= -0.40 \pm 0.23 \pm 0.03$, where the
first error is statistical and the second systematic. We also explore $B^0 \to
K^{0}_s\pi^0\gamma$ decays with $1.1<m_{K^{0}_s\pi^0}<1.8$ GeV$/c^2$ and find
$59\pm13$ signal events with $S_{K^{0}_s\pi^0} = 0.9 \pm 1.0 \pm 0.2$ and
$C_{K^{0}_s\pi^0} = -1.0 \pm 0.5 \pm 0.2$.


title:
Measurement of the branching fraction, polarization, and CP asymmetry in
  B0 -> rho+rho- decays

abstract:
  We have measured the branching fraction, longitudinal polarization fraction
f_L, and the CP asymmetry coefficients A and S in B0 -> rho+rho- decays. These
results are obtained from a 253 fb-1 data sample containing 275 million
B\bar{B} pairs collected by the Belle detector running at the KEKB e+e-
collider. We obtain B = [24.4 \pm 2.2 (stat) +3.8 -4.1 (syst)] x 10-6, f_L =
0.951 +0.033 -0.039 (stat) +0.029 -0.031 (syst), A = 0.00 \pm 0.30 (stat) +0.10
-0.09 (syst), and S = 0.09 \pm 0.42 (stat) \pm 0.08 (syst). These values are
used to determine the CKM phase angle phi_2 (alpha) via an isospin analysis;
the central value and one sigma error are (87 \pm 17) degrees, and 59 degrees <
phi_2 < 115 degrees at 90% CL.


title: NuTeV Structure Function Measurement

abstract:
  The NuTeV experiment obtained high statistics samples of neutrino and
anti-neutrino charged current events during the 1996-1997 Fermilab fixed target
run. The experiment combines sign-selected neutrino and anti-neutrino beams and
the upgraded CCFR iron-scintillator neutrino detector. A precision continuous
calibration beam was used to determine the muon and hadron energy scales to a
precision of 0.7% and 0.43% respectively. The structure functions F_2(x,Q^2)
and xF_3(x,Q^2) obtained by fitting the y-dependence of the sum and the
difference of the neutrino and anti-neutrino differential cross sections are
presented.


title:
Measurement of the Cross Section for Open-Beauty Production in
  Photon-Photon Collisions at LEP

abstract:
  The cross section for open-beauty production in photon-photon collisions is
measured using the whole high-energy and high-luminosity data sample collected
by the L3 detector at LEP. This corresponds to 627/pb of integrated luminosity
for electron-positron centre-of-mass energies from 189GeV to 209GeV. Events
containing b quarks are identified through their semi-leptonic decay into
electrons or muons. The e+e- -> e+e-b b~X cross section is measured within our
fiducial volume and then extrapolated to the full phase space. These results
are found to be in significant excess with respect to Monte Carlo predictions
and next-to-leading order QCD calculations.


title:
Measurement of the Photon Structure Function F2gamma with the L3
  Detector at LEP

abstract:
  The e+e- -> e+e- hadrons reaction, where one of the two electrons is detected
in a low polar-angle calorimeter, is analysed in order to measure the hadronic
photon structure function F2gamma . The full high-energy and high-luminosity
data set, collected with the L3 detector at centre-of-mass energies 189-209GeV,
corresponding to an integrated luminosity of 608/pb is used. The Q^2 range
11-34GeV^2 and the x range 0.006-0.556 are considered. The data are compared
with recent parton density functions.


title:
Study of sequential semileptonic decays of b hadrons produced at the
  Tevatron

abstract:
  We present a study of rates and kinematical properties of lepton pairs
contained in central jets with transverse energy E_T > 15 GeV that are produced
at the Fermilab Tevatron collider. We compare the data to a QCD prediction
based on the HERWIG and QQ Monte Carlo generator programs.We find that the data
are poorly described by the simulation, in which sequential semileptonic decays
of single b quarks (b --> l c X with c --> l s X) are the major source of such
lepton pairs.


title: Search for narrow resonances below the Upsilon mesons

abstract:
  We have investigated the invariant mass spectrum of dimuons collected by the
CDF experiment during the 1992-1995 run of the Fermilab Tevatron collider to
improve the limit on the existence of narrow resonances set by the experiments
at the SPEAR e+e- collider. In the mass range 6.3-9.0 GeV/c^2, we derive 90%
upper credible limits to the ratio of the production cross section times muonic
branching fraction of possible narrow resonances to that of the Y(1S) meson. In
this mass range, the average limit varies from 1.7 to 0.5%. This limit is much
worse at the mass of 7.2 GeV/c^2 due to an excess of 250+-61 events with a
width consistent with the detector resolution.


title:
Improved Measurements of Direct CP Violation in B --> K+pi-, K+pi0 and
  pi+pi0 Decays

abstract:
  We report an improved measurement of direct CP violation in the decay B0 -->
K+pi-, and a search for CP violation in the decays B+ --> K+pi0 and B+ -->
pi+pi0. The measured CP violating asymmetries are
Acp(K+pi-)=-0.113+-0.022(stat.)+-0.008(syst.),
Acp(K+pi0)=0.04+-0.04(stat.)+-0.02(syst.) and
Acp(pi+pi0)=0.02+-0.08(stat.)+-0.01(syst.), where the latter correspond to the
intervals -0.03<Acp(K+pi0)<0.11 and -0.12<Acp(pi+pi0)<0.15 at 90% confidence
level. These results are obtained from a data sample that contains 386 million
BBbar pairs that was collected near the Y(4S) resonance, with the Belle
detector at the KEKB asymmetric nergy e+e- collider. All of the results are
preliminary.


title:
Measurement of Semileptonic Branching Fractions of B Mesons to Narrow
  D** States

abstract:
  Using the data accumulated in 2002-2004 with the DO detector in
proton-antiproton collisions at the Fermilab Tevatron collider with
centre-of-mass energy 1.96 TeV, the branching fractions of the decays B ->
\bar{D}_1^0(2420) \mu^+ \nu_\mu X and B -> \bar{D}_2^{*0}(2460) \mu^+ \nu_\mu X
and their ratio have been measured: BR(\bar{b}->B) \cdot BR(B-> \bar{D}_1^0
\mu^+ \nu_\mu X) \cdot BR(\bar{D}_1^0 -> D*- pi+) =
(0.087+-0.007(stat)+-0.014(syst))%; BR(\bar{b}->B)\cdot BR(B->D_2^{*0} \mu^+
\nu_\mu X) \cdot BR(\bar{D}_2^{*0} -> D*- \pi^+) =
(0.035+-0.007(stat)+-0.008(syst))%; and (BR(B -> \bar{D}_2^{*0} \mu^+ \nu_\mu
X)BR(D2*0->D*- pi+)) / (BR(B -> \bar{D}_1^{0} \mu^+ \nu_\mu X)\cdot
BR(\bar{D}_1^{0}->D*- \pi^+)) = 0.39+-0.09(stat)+-0.12(syst), where the charge
conjugated states are always implied.


title: Determination of alpha_s using Jet Rates at LEP with the OPAL detector

abstract:
  Hadronic events produced in e+e- collisions by the LEP collider and recorded
by the OPAL detector were used to form distributions based on the number of
reconstructed jets. The data were collected between 1995 and 2000 and
correspond to energies of 91 GeV, 130-136 GeV and 161-209 GeV. The jet rates
were determined using four different jet-finding algorithms (Cone, JADE, Durham
and Cambridge). The differential two-jet rate and the average jet rate with the
Durham and Cambridge algorithms were used to measure alpha(s) in the LEP energy
range by fitting an expression in which order alpah_2s calculations were
matched to a NLLA prediction and fitted to the data. Combining the measurements
at different centre-of-mass energies, the value of alpha_s (Mz) was determined
to be
alpha(s)(Mz)=0.1177+-0.0006(stat.)+-0.0012$(expt.)+-0.0010(had.)+-0.0032(theo.)

title:
Searches for Gauge-Mediated Supersymmetry Breaking Topologies in e+e-
  collisions at LEP2

abstract:
  Searches were performed for topologies predicted by gauge-mediated
Supersymmetry breaking models (GMSB). All possible lifetimes of the
next-to-lightest SUSY particle (NLSP), either the lightest neutralino or
slepton, decaying into the lightest SUSY particle, the gravitino, were
considered. No evidence for GMSB signatures was found in the OPAL data sample
collected at centre-of-mass energies of sqrt{s}=189-209 GeV at LEP. Limits on
the product of the production cross-sections and branching fractions are
presented for all search topologies. To test the impact of the searches, a
complete scan over the parameters of the minimal model of GMSB was performed.
NLSP masses below 53.5 GeV/c^2 in the neutralino NLSP scenario, below 87.4
GeV/c^2 in the stau NLSP scenario and below 91.9 GeV/c^2 in the slepton co-NLSP
scenario are excluded at 95% confidence level for all NLSP lifetimes. The scan
determines constraints on the universal SUSY mass scale Lambda from the direct
SUSY particle searches of Lambda > 40,27,21,17,15 TeV/c^2 for messenger indices
N=1,2,3,4,5 for all NLSP lifetimes.


title: Recent measurement of Delta G/G at COMPASS

abstract:
  We present a preliminary measurement of the gluon polarization Delta G/G in
the nucleon, based on the spin asymmetry of quasi-real photoproduction events
for which a pair of large transverse momentum hadrons is produced. The data
were obtained by the COMPASS experiment at CERN using a 160 GeV polarized muon
beam scattered on a large polarized 6LiD target. The preliminary helicity
asymmetry for the selected events is A_||/D = 0.002 +- 0.019(stat) +-
0.003(syst). From this value, a leading order analysis based on the model of
PYTHIA leads to the gluon polarization in the nucleon Delta G/G(x_g=0.095,
mu^2=3 GeV^2)=0.024 +- 0.089(stat) +- 0.057(syst). This value is consistent
with parameterizations obtained from QCD fits to the g_1 data, with a first
moment Delta G lower than 1, at the same scale.


title: Trilinear Gauge Couplings from gamma/gamma to WW

abstract:
  If there is no the Standard Model Higgs boson, the interaction among the
gauge bosons becomes strong at high energies (~ 1TeV). The effects of strong
electroweak symmetry breaking could manifest themselves indirectly through the
vertices as anomalous gauge boson couplings before they give rise to new
physical states like resonances. Here a study of the measurement of trilinear
gauge couplings kappa_gamma and lambda_gamma is presented looking at the
hadronic decay channel of the WW boson pair at an gamma/gamma-collider. A
sensitivity of order of 0.001-0.0001 can be reached depending on the coupling
under consideration and on the initial polarisation state.


title:
Search for W and Z Bosons in the Reaction \bar{p}p \to 2 jets + \gamma
  at \sqrt{s} = 1.8 TeV

abstract:
  We present a study of the dijet invariant mass distribution for the reaction
$\pbp \to 2 $jets$+\gamma+X$, at a center of mass energy of 1.8 TeV, using data
collected by the CDF experiment. We compare the data to predictions for the
production of a photon with two jets, together with the resonant processes
$\pbp \to W/Z+\gamma+X$, in which the $W$ and $Z$ bosons decay hadronically. A
fit is made to the dijet invariant mass distribution combining the non-resonant
background and resonant processes. We use the result to establish a limit for
the inclusive production cross section of $W/Z+\gamma$ with hadronic decay of
the $W$ and $Z$ bosons.


title:
Measurement of Time-dependent CP-Violating Asymmetries in B^0 -> K^0_S
  K^0_S K^0_S Decays

abstract:
  We present preliminary measurements of the CP asymmetry parameters in B^0 ->
K^0_S K^0_S K^0_S decays, reconstructing two of the K^0_S into pi^+pi^- and one
into pi^0pi^0. In a sample of 227M $B\bar B$ pairs collected by the BABAR
detector at the PEP-II B-Factory at SLAC, we find the CP parameters to be S =
-0.25^{+0.68}_{-0.61} (stat) +/- 0.05 (syst) and C = 0.56^{+0.34}_{-0.43}
(stat) +/- 0.04 (syst).
  Combining this result with the previous BABAR measurement, obtained from
events with three K^0_S decaying into pi^+pi^-, we get
  S = -0.63^{+0.32}_{-0.28} (stat) +/- 0.04(syst) C = -0.10 +/- 0.25 (stat) +/-
0.05 (syst)


title:
Selectron Mass Reconstruction and the Resolution of the Linear Collider
  Detector

abstract:
  We have used ISAJET and the JAS LCD fast simulation to explore the precision
of Snowmass Point SPS1a selectron mass reconstruction for the Silicon Detector
concept. Simulating collisions at E_cm = 1 TeV, we have found that most of the
information constraining the selectron mass is carried in the forward
(|cos(theta)| > 0.8) region. We have also found that, for a beam energy spread
of 1% (conventional RF design), detector resolution limitations compromise the
selectron mass reconstruction only in the forward region. However, for a beam
energy spread of less than 0.2% (superconducting RF design), the detector
resolution compromises the selectron mass reconstruction over the full angular
region.


title:
Measurement of the B0bar Lifetime and the B0B0bar Oscillation Frequency
  Using Partially Reconstructed B0bar --> D*+ ell- nu-bar Decays

abstract:
  We present a simultaneous measurement of the B0bar lifetime tau_B0 and
B0B0bar oscillation frequency Delta_md. We use a sample of about 50000
partially reconstructed B0bar --> D*+ ell- nu-bar decays identified with the
BABAR detector at the PEP-II e+e- storage ring at SLAC. The flavor of the other
B meson in the event is determined from the charge of another high-momentum
lepton. The results are tau_B0 = (1.504 +/- 0.013 (stat) {+0.018}/{-0.013}
(syst)) ps, Delta_md = (0.511 +/- 0.007 (stat) {+0.007}/{-0.006} (syst)) ps-1


title:
COSY-11: an experimental facility for studying meson production in free
  and quasi-free nucleon-nucleon collisions

abstract:
  The COSY-11 experimental setup is an internal facility installed at the
COoler SYnchrotron COSY in Juelich. It allows to investigate meson production
in free and quasi-free nucleon-nucleon collisions, eg. pp --> pp meson and pd
--> p_sp np meson reactions. Drift chambers and scintillators permit to measure
outgoing protons, separated in magnetic field of COSY-11 dipole. Neutrons are
registered in the neutron modular detector installed downstream the beam.
Recently, the experimental setup has been extended with spectator detector,
deuteron drift chamber and polarization monitoring system, and since then meson
production can be investigated also as a function of spin and isospin of
colliding nucleons.


title: Search for Exotic Baryons in 800 GeV pp (rtarrow) pXiPiX

abstract:
  We report the results of a high-statistics, sensitive search for narrow
baryon resonances decaying to $\Xi^-\pi^-$, $\Xi^-\pi^+$, $\bar{\Xi}^+\pi^-$,
and $\bar{\Xi}^+\pi^+$. The only resonances observed are the well known
$\Xi^0(1530)$ and $\bar{\Xi^0}(1530)$. No evidence is found for a state near
1862 MeV, previously reported by NA49\cite{NA49}. At the 95% confidence level,
we find the upper limit for the production of a Gaussian enhancement with
$\sigma=7.6$ MeV in the $\Xi^-\pi^-$ effective mass spectrum to be 0.3% of the
number of observed $\Xi^0(1530)\to\Xi^-\pi^+$. We find similarly restrictive
upper limits for an enhancement at 1862 MeV in the $\Xi^-\pi^+$,
$\bar{\Xi}^+\pi^-$, and $\bar{\Xi}^+\pi^+$ mass spectra.


title: Recent Results from CLEO

abstract:
  We report the initial results from CLEO-c based on the 55.8/pb data obtained
at the psi(3770) resonance last year. We give a concise summary of the various
CLEO-c analyses on leptonic and semileptonic decays of neutral and charged D
mesons. The data used for this report is the first part of the psi(3770) data
sets to be collected during next several years using the Cornell Electron
Storage Ring. Most of the results shown here have already better or the same
level of precision compared to the 2004 world averages compiled by the Particle
Data Group.

Integral Fluxes, Day-Night, and Spectrum Results from SNO's 391-Day Salt
  Phase

abstract:
  The Sudbury Neutrino Observatory is a 1000t heavy water Cherenkov detector
observing neutrinos from the Sun and other astrophysical sources. Measurements
of the integral solar neutrino fluxes of charged current, neutral current and
elastic scattering events are reported for 391 days of live data from the salt
phase of SNO operation. In this phase 2t of salt were dissolved in the heavy
water, which enhanced and differentiated the detection of neutral current
events. Day-night asymmetries in these fluxes were also determined. The
measured electron spectrum from the charged-current channel is compatible with
the undistorted spectrum of the solar 8B neutrino flux.


title: Time-Dependent CP Asymmetries in B0 -> Ks Pi0 gamma transition

abstract:
  We present measurements of CP-violation parameters in b -> s gamma
transitions based on a sample of 386x10^6 BB pairs collected at the Y(4S)
resonance with the Belle detector at the KEKB energy-asymmetric e+e- collider.
One neutral B meson is fully reconstructed in the B0 -> Ks Pi0 gamma decay
channel irrespective to the Ks Pi0 intermediate state. The flavor of the
accompanying B meson is identified from its decay products. CP-violation
parameters are obtained from the asymmetries in the distributions of the
proper-time intervals between the two B decays.
  We obtain the following results for the Ks Pi0 invariant mass covering the
full range up to 1.8 GeV/c^2: S_{Ks Pi0 gamma} = +0.08 +-0.41(stat)
+-0.10(syst), A_{Ks Pi0 gamma} = +0.12 +-0.27(stat) +-0.10(syst).


title:
Measurement of the branching fractions for B- --> D(*)+ pi- l- nu-bar
  and B0bar --> D(*)0 pi+ l- nu-bar

abstract:
  We report on a measurement of the branching fractions for B- --> D(*)+ pi- l-
nu-bar and B0bar --> D(*)0 pi+ l- nu-bar with 275 million BBbar events
collected at the Upsilon(4S) resonance with the Belle detector at KEKB. Events
are tagged by fully reconstructing one of the B mesons in hadronic modes. We
obtain Br(B- --> D+ pi- l- nu-bar) = (0.54 +/- 0.07(stat) +/- 0.07(syst) +/-
0.06(BR)) x 10^-2, Br(B- --> D*+ pi- l- nu-bar) = (0.67 +/- 0.11(stat) +/-
0.09(syst) +/- 0.03(BR)) x 10^-2, Br(B0bar --> D0 pi+ l- nu-bar) = (0.33 +/-
0.06(stat) +/- 0.06(syst) +/- 0.03(BR)) x 10^-2, Br(B0bar --> D*0 pi+ l-
nu-bar) = (0.65 +/- 0.12(stat) +/- 0.08(syst) +/- 0.05(BR)) x 10^-2, where the
third error comes from the error on Bbar --> D(*) l- nu-bar decays.
Contributions from B0bar --> D*+ l- nu-bar decays are excluded in the
measurement of B0bar --> D0 pi+ l- nu-bar.


title: PVLAS results

abstract:
  The PVLAS experiment has built an apparatus to measure rotations and
ellipticities induced by a transverse magnetic field onto linearly polarized
laser light.Available results can be interpreted as observation of an
unexpectedly large rotation effect between 10-7 and 4 10-7rad. If this rotation
is due to the existence of a light spin zero boson of mass m and coupling to
two photons 1/M, the ball-park values of the boson mass parameters are m=1meV
and M=10+6GeV.


title: Searches for Higgs Boson(s) at the Upgraded Tevatron

abstract:
  We summarize the status of Higgs boson searches at the upgraded Fermilab
Tevatron performed by the DO and CDF collaborations. We report on three
categories of searches, namely 1) the search for the Standard Model Higgs boson
(p\bar{p} --> H, WH or ZH, with H --> WW* and/or H --> b\bar{b}), 2) the search
for the minimal supersymmetric Higgs boson using p\bar{p} --> hb\bar{b} -->
b\bar{b}b\bar{b} and p\bar{p} --> hX --> tau tau X, 3) the search for doubly
charged Higgs boson.


title:
Measurement of Azimuthal Asymmetries in Inclusive Production of Hadron
  Pairs in e+e- Annihilation at Belle

abstract:
  The Collins effect connects transverse quark spin with a measurable azimuthal
dependence in the yield of hadronic fragments around the quark's momentum
vector. Using two different reconstruction methods we observe statistically
significant azimuthal asymmetries for charged pion pairs in e+e- annihilation
at a center-of-mass energy of 10.52 GeV, which can be attributed to a
transverse polarization of the primordial quarks. The measurement was performed
using a sample of 79 million hadronic events collected with the Belle detector.


title: Improved Measurements of B0bar -> DsJ+ K- decays

abstract:
  We report an improved measurement of the branching fraction for B0bar ->
DsJ*(2317)+ K- and present evidence of the B0bar -> DsJ(2460)+ K- decay. These
results are obtained from a data sample containing 386 million BBbar pairs that
was collected near the Y(4S) resonance, with the Belle detector at the KEKB
asymmetric energy e+ e- collider.


title: Measurement of phi1 using B --> D[Ks pi+ pi-] h0

abstract:
  We present a preliminary measurement of the angle phi1 of the CKM Unitarity
Triangle using time-dependent analysis of D -> Ks pi+ pi- decays produced in
neutral B meson decay to a neutral D meson and a light meson (B -> D h). The
method allows one to directly extract the value of 2phi1. The ambiguity between
2phi1 and pi-2phi1 in the measurement of sin(2phi1) can then be resolved. We
obtain phi1=16 +- 21 +- 11. The 95% CL region including systematic error is
-30<phi1<62, thus ruling out the second solution from sin(2phi1)=0.726 +- 0.037
at the 97% CL.


title: Bose-Einstein Correlations in W+W- events at LEP2

abstract:
  Bose-Einstein correlations (BEC) between final state particles in the
reaction e+e- -> W+W- -> q_1 anti-q_2 q_3 anti-q_4 have been studied. Data
corresponding to a total integrated luminosity of 550 pb^{-1}, recorded by the
DELPHI detector at centre-of-mass energies ranging from 189 to 209 GeV, were
analysed. An indication for inter-W BEC between like-sign particles has been
found at the level of 2.4 standard deviations of the combined statistical and
systematic uncertainties.

Search for Lambda_b -> p pi and Lambda_b -> p K decays in p-pbar
  collisions at sqrt(s) = 1.96 TeV

abstract:
  We report on a search for Lambda_b -> p pi- and Lambda_b -> p K- (and charge
conjugate) decays in p-pbar collisions at sqrt(s) = 1.96 TeV using 193 pb-1 of
data collected by CDFII experiment at the Fermilab Tevatron Collider. Data were
collected using a track trigger that has been optimized to select tracks
belonging to a secondary vertex that is typical of two body charmless decays of
b-flavored hadrons, including Lambda_b baryons. As no Lambda_b signal was
observed, we set the upper limits on the branching fractions BR(Lambda_b -> p
h-) where h is K or pi, of 2.3x10-5 at 90% C.L. and 2.9x10-5 at 95% C.L.


title: Neutrino Oscillation Effects in Soudan-2 Upward-stopping muons

abstract:
  Upward-going stopping muons initiated by atmospheric \numu and \anumu
interactions in the rock below the Soudan 2 detector have been isolated,
together with a companion sample of neutrino-induced single muons, created
within the detector, which travel downwards and exit. The downward-going sample
is consistent with the atmospheric-neutrino flux prediction, but the
upward-going sample exhibits a sizeable depletion. Both are consistent with
previously reported Soudan-2 neutrino-oscillation results. Inclusion of the two
samples in an all-event likelihood analysis, using recent
3D-atmospheric-neutrino-flux calculations, reduces both the allowed oscillation
parameter region and the probability of the no-oscillation hypothesis.


title: A Search for the Decay B+ --> tau+ nu_tau

abstract:
  We search for the rare leptonic decay B+ --> tau+ nu_tau in a sample of
232x10^6 BBbar pairs collected with the BABAR detector at the SLAC PEP-II
B-Factory. Signal events are selected by examining the properties of the B
meson recoiling against the semileptonic decay B- --> D*0 l- nu_lbar. We find
no evidence for a signal and set an upper limit on the branching fraction of
BR(B+ --> tau+ nu_tau) < 2.8x10^{-4} at the 90% confidence level. We combine
this result with a previous, statistically independent BABAR search for B+ -->
tau+ nu_tau to give an upper limit of BR(B+ --> tau+ nu_tau) < 2.6x10^{-4} at
the 90% confidence level.


title: Comparison of photon colliders based on e-e- and e+e- beams

abstract:
  At photon colliders gamma-gamma, gamma-electron high energy photons are
produced by Compton scattering of laser light off the high energy electrons (or
positrons) at a linear collider. At first sight, photon colliders based on e-e-
or e+e- primary beams have similar properties and therefore for convenience one
can use e+e- beams both for e+e- and gamma-gamma modes of operation. Below we
compare these options and show that e-e- beams are much better (mandatory)
because in the e+e- case low energy background gamma-gamma to hadrons is much
higher and e+e- annihilation reactions present a very serious background for
gamma-gamma processes.


title:
Measurement of the wrong-sign decays D0 -> K+ pi- pi0 and D0 -> K+ pi-
  pi+ pi-, and search for CP violation

abstract:
  Using 281 fb^-1 of data from the Belle experiment recorded at or near the
Upsilon(4S) resonance, we have measured the rates of the ``wrong-sign'' decays
D0 -> K+ pi- pi0 and D0 -> K+ pi- pi+ pi- relative to those of the
Cabibbo-favored decays D0 -> K- pi+ pi0 and D0 -> K- pi+ pi+ pi-. These
wrong-sign decays proceed via a doubly Cabibbo-suppressed amplitude or via
D0-D0bar mixing; the latter has not yet been observed. We obtain
R_WS(Kpipi0)=[0.229 +/-0.017(stat.) +0.013-0.009(sys.)]% and R_WS(K3pi)=[0.320
+/-0.019(stat.) +0.018-0.013(sys.)]%. The CP asymmetries are measured to be
-0.006 +/- 0.053 and -0.018 +/- 0.044 for the K+ pi- pi0 and K+ pi- pi+ pi-
final states, respectively.

future prospects.


title:
Measurement of Transverse Single-Spin Asymmetries for Mid-rapidity
  Production of Neutral Pions and Charged Hadrons in Polarized p+p Collisions
  at sqrt(s) = 200 GeV

abstract:
  The transverse single-spin asymmetries of neutral pions and non-identified
charged hadrons have been measured at mid-rapidity in polarized proton-proton
collisions at sqrt(s) = 200 GeV. The data cover a transverse momentum (p_T)
range 0.5-5.0 GeV/c for charged hadrons and 1.0-5.0 GeV/c for neutral pions, at
a Feynman-x (x_F) value of approximately zero. The asymmetries seen in this
previously unexplored kinematic region are consistent with zero within
statistical errors of a few percent. In addition, the inclusive charged hadron
cross section at mid-rapidity from 0.5 < p_T < 7.0 GeV/c is presented and
compared to NLO pQCD calculations. Successful description of the unpolarized
cross section above ~2 GeV/c using NLO pQCD suggests that pQCD is applicable in
the interpretation of the asymmetry results in the relevant kinematic range.


title:
Measurements of the Branching Fraction and Time-Dependent CP-Asymmetries
  of B0->J/Psi pi0 Decays

abstract:
  We present measurements of the branching fraction and time-dependent CP
asymmetries in B0->J/Psi pi0 decays based on (231.8 +/- 2.6)*10^6 Upsilon(4S)
-> BBbar decays collected with the BaBar detector at the PEP-II
asymmetric-energy B factory at SLAC during the years 1999-2004. We obtain a
branching fraction B(B0->J/Psi pi0) = (1.94 +/- 0.22 (stat) +/- 0.17
(syst))*10^-5. We also measure the CP asymmetry parameters C = -0.21 +/- 0.26
(stat) +/- 0.09 (syst) and S = -0.68 +/- 0.30 (stat) +/- 0.04 (syst). All
results presented in this paper are preliminary.


title:
Measurement of CP-voilating parameters in fully reconstructed
  B->D(*)+-pi-+ and B->D+-rho-+ decays

abstract:
  We present a preliminary measurement of the CP-violating parameters in fully
reconstructed B->D^(*)+-pi-+ and B->D^+-rho-+ decays in approximately 232
million Y(4S)->BBbar$ decays collected with the BaBar detector at the PEP-II
asymmetric-energy B factory at SLAC.
  From a maximum likelihood fit to the time-dependent decay distributions we
obtain for the parameters related to the CP violation quantity
sin(2beta+gamma): a[Dpi] = -0.013 +/- 0.022 (stat.) +/- 0.007 (syst.),
clep[Dpi] = -0.043 +/- 0.042 (stat.) +/- 0.011 (syst.), a[D*pi] = -0.043 +/-
0.023 (stat.) +/- 0.010 (syst.), clep[D*pi] = 0.047 +/- 0.042 (stat.) +/- 0.015
(syst.), a[Drho] = -0.024 +/- 0.031 (stat.) +/- 0.010 (syst.), clep[Drho] =
-0.098 +/- 0.055 (stat.) +/- 0.019 (syst.).


title:
Isospin dependence of the eta' meson production in nucleon--nucleon
  collisions

abstract:
  According to the quark model, the masses of eta and eta' mesons should be
almost equal. However, the empirical values of these masses differ by more than
the factor of two. Similarly, though the almost the same quark-antiquark
content, the total cross section for the creation of these mesons close to the
kinematical thresholds in the pp --> ppX reaction differs significantly. Using
the COSY-11 detection setup we intend to determine whether this difference will
also be so significant in the case of the production of these mesons in the
proton-neutron scattering. Additionally, the comparison of the pp --> pp eta'
and pn --> pn eta' total cross sections will allow to learn about the
production of the eta' meson in the channels of isospin I = 0 and I = 1 and to
investigate aspects of the gluonium component of the eta' meson.

title:
Measurement of the Running of the Electromagnetic Coupling at Large
  Momentum-Transfer at LEP

abstract:
  The evolution of the electromagnetic coupling, alpha, in the
momentum-transfer range 1800GeV^2 < -Q^2 < 21600GeV^2 is studied with about
40000 Bhabha-scattering events collected with the L3 detector at LEP at
centre-of-mass energies 189-209GeV. The running of alpha is parametrised as:
alpha(Q^2) = alpha_0/(1-C Delta alpha(Q^2)), where alpha_0=\alpha(Q^2=0) is the
fine-structure constant and C=1 corresponds to the evolution expected in QED. A
fit to the differential cross section of the e+e- ->e+e- process for scattering
angles in the range |cos theta|<0.9 excludes the hypothesis of a constant value
of alpha, C=0, and validates the QED prediction with the result: C = 1.05 +/-
0.07 +/- 0.14, where the first uncertainty is statistical and the second
systematic.


title:
A Search for Periodicities in the $^8$B Solar Neutrino Flux Measured by
  the Sudbury Neutrino Observatory

abstract:
  A search has been made for sinusoidal periodic variations in the $^8$B solar
neutrino flux using data collected by the Sudbury Neutrino Observatory over a
4-year time interval. The variation at a period of one year is consistent with
modulation of the $^8$B neutrino flux by the Earth's orbital eccentricity. No
significant sinusoidal periodicities are found with periods between 1 day and
10 years with either an unbinned maximum likelihood analysis or a Lomb-Scargle
periodogram analysis. The data are inconsistent with the hypothesis that the
results of the recent analysis by Sturrock et al., based on elastic scattering
events in Super-Kamiokande, can be attributed to a 7% sinusoidal modulation of
the total $^8$B neutrino flux.


title: A Determination of Electroweak Parameters at HERA

abstract:
  Using the deep inelastic e^+p and e^-p charged and neutral current scattering
cross sections previously published, a combined electroweak and QCD analysis is
performed to determine electroweak parameters accounting for their correlation
with parton distributions. The data used have been collected by the H1
experiment in 1994-2000 and correspond to an integrated luminosity of 117.2
pb^{-1}. A measurement is obtained of the W propagator mass in charged current
ep scattering. The weak mixing angle sin^2 theta_W is determined in the
on-mass-shell renormalisation scheme. A first measurement at HERA is made of
the light quark weak couplings to the Z^0 boson and a possible contribution of
right-handed isospin components to the weak couplings is investigated.


title:
Measurement of F_2^{c\bar{c}} and F_2^{b\bar{b}} at Low Q^2 and x using
  the H1 Vertex Detector at HERA

abstract:
  Measurements are presented of inclusive charm and beauty cross sections in
e^+p collisions at HERA for values of photon virtuality 12 \le Q^2 \le 60 GeV^2
and of the Bjorken scaling variable 0.0002 \le x \le 0.005. The fractions of
events containing charm and beauty quarks are determined using a method based
on the impact parameter, in the transverse plane, of tracks to the primary
vertex, as measured by the H1 vertex detector. Values for the structure
functions F_2^{c\bar{c}} and F_2^{b\bar{b}} are obtained. This is the first
measurement of F_2^{b\bar{b}} in this kinematic range. The results are found to
be compatible with the predictions of perturbative quantum chromodynamics and
withprevious measurements of F_2^{c\bar{c}}.


title: Detecting Antihydrogen: The Challenges and the Applications

abstract:
  ATHENA's first detection of cold antihydrogen atoms relied on their
annihilation signatures in a sophisticated particle detector. We will review
the features of the ATHENA detector and its applications in trap physics. The
detector for a new experiment ALPHA will have considerable challenges due to
increased material thickness in the trap apparatus as well as field
non-uniformity. Our studies indicate that annihilation vertex imaging should be
still possible despite these challenges. An alternative method for trapped
antihydrogen, via electron impact ionization, will be also discussed.


title:
First results of the search of neutrinoless double beta decay with the
  NEMO 3 detector

abstract:
  The NEMO 3 detector, which has been operating in the Frejus underground
laboratory since February 2003, is devoted to the search for neutrinoless
double beta decay (bb0nu). Half-lives of the two neutrino double beta decays
(bb2nu) have been measured for 100Mo and 82Se. After 389 effective days of data
collection from February 2003 until September 2004 (Phase I), no evidence for
neutrinoless double beta decay was found from ~7kg of 100Mo and ~1 kg of 82Se.
The corresponding lower limits for the half-lives are 4.6 x 10^23 years for
100Mo and 1.0 x10^23 years for 82Se (90% C.L.). Depending on the nuclear matrix
elements calculation, limits for the effective Majorana neutrino mass are <m> <
0.7-2.8 eV for 100Mo and <m> < 1.7-4.9 eV for 82Se


title: Measurement of the Lifetime Difference in the B_s^0 System

abstract:
  We present a study of the decay B_s^0 -> J/psi phi We obtain the CP-odd
fraction in the final state at time zero, R_perp = 0.16 +/- 0.10 (stat) +/-
0.02 (syst), the average lifetime of the (B_s, B_sbar) system, tau (B_s^0)
=1.39^{+0.13}_{-0.16} (stat) ^{+0.01}_{-0.02} (syst) ps, and the relative width
difference between the heavy and light mass eigenstates, Delta Gamma/Gamma =
(Gamma_L - Gamma_H)/Gamma =0.24^{+0.28}_{-0.38} (stat) ^{+0.03}_{-0.04} (syst).
With the additional constraint from the world average of the B_s^0$lifetime
measurements using semileptonic decays, we find tau (B_s^0)= 1.39 +/- 0.06 ~ps
and Delta Gamma/\Gamma = 0.25^{+0.14}_{-0.15}. For the ratio of the B_s^0 and
B^0 lifetimes we obtain tau(B_s^0)/tau(B^0)} = 0.91 +/- 0.09 (stat) +/- 0.003
(syst).


title:
Measurement of the B0 --> pi- l+ nu and B+ --> pi0 l+ nu Branching
  Fractions and Determination of |V_ub| in Y(4S) Events Tagged by a Fully
  Reconstructed B Meson

abstract:
  We report preliminary measurements of the charmless exclusive semileptonic
branching fractions of the B0 --> pi- l+ nu and B+ --> pi0 l+ nu decays, based
on 211 fb-1 of data collected at the Y(4S) resonance by the BABAR detector. In
events in which the decay of one B meson to a hadronic final state is fully
reconstructed, the semileptonic decay of the second B meson is identified by
the detection of a charged lepton and a pion. We measure the partial branching
fractions for B0 --> pi- l+ nu and B+ --> pi0 l+ nu in three regions of the
invariant mass squared of the lepton pair, and we obtain the total branching
fractions BF(B0 --> pi- l+ nu) = (1.14 +/- 0.27(stat) +/- 0.17(syst)) x 10^-4
and BF(B+ --> pi0 l+ nu) = (0.86 +/- 0.22(stat) +/- 0.11(syst)) x 10^-4. Using
isospin symmetry, we measure the combined total branching fraction BF(B0 -->
pi- l+ nu) = (1.28 +/- 0.23(stat) +/- 0.16(syst)) x 10^-4. Theoretical
predictions of the form-factor are used to determine the magnitude of the
Cabibbo-Kobayashi-Maskawa matrix element |V_ub| = (3.7 +/- 0.3(stat) +/-
0.2(syst) +0.8-0.5(FF)) x 10^-3, where the last error is due to the form-factor
normalization.


title:
Mass limits for fourth generation sequential neutrinos from dark matter
  experiments

abstract:
  Current mass limits for fourth generation sequential neutrinos come from dark
matter experiments assuming $\rho_{DM}=0.2-0.8$ g/ cm$^3$. We show that the
latest results from the CDMS II experiment exclude Dirac neutrinos with masses
below 500 GeV assuming only that they are produced as expected by the Big Bang
model and clump in the same manner as baryons. We also show the next generation
of nuclear recoil experiments will be sensitive to fourth generation Majorana
nuetrinos. Finally, we consider the case in which the neutrino interacts with
the nucleus via the exchange of a Higgs boson.


title:
Measurement of Time-Dependent CP-Violating Asymmetries in B0 Meson
  Decays to eta'K0L

abstract:
  We present a preliminary measurement of CP-violating parameters S and C from
fits of the time-dependence of B0 meson decays to eta'K0L. The data were
recorded with the BABAR detector at PEP-II and correspond to 232 10^6 BBbar
pairs produced in e+e- annihilation through the Y(4S) resonance. By fitting the
time-dependent CP asymmetry of the reconstructed B0 --> eta'K0L events, we find
S = 0.60 +- 0.31 +- 0.04 and C = 0.10 +- 0.21 +- 0.03, where the first error
quoted is statistical and the second is systematic. We also perform a combined
fit using both eta'K0S and eta'K0L data, and find S = 0.36 +- 0.13 +- 0.03 and
C = -0.16 +- 0.09 +- 0.02.


title: Measurement of the KL meson lifetime with the KLOE detector

abstract:
  We present a measurement of the KL lifetime using the KLOE detector. From a
sample of 4 x 10^8 KS KL pairs following the reaction e+ e- -> phi -> KS KL we
select 15 x 10^6 KL -> p0 p0 p0 decays tagged by KS -> pi+ pi- events. From a
fit of the proper time distribution we find tau_L = (50.92 +- 0.17{stat} +-
0.25{syst})$ ns. This is the most precise measurement of the KL lifetime
performed to date.


title:
Inclusive jet cross sections and dijet correlations in $D^{*\pm}$
  photoproduction at HERA

abstract:
  Inclusive jet cross sections in photoproduction for events containing a $D^*$
meson have been measured with the ZEUS detector at HERA using an integrated
luminosity of $78.6 {\rm pb}^{-1}$. The events were required to have a
virtuality of the incoming photon, $Q^2$, of less than 1 GeV$^2$, and a
photon-proton centre-of-mass energy in the range $130<W_{\gamma p}<280 {\rm
GeV}$. The measurements are compared with next-to-leading-order (NLO) QCD
calculations. Good agreement is found with the NLO calculations over most of
the measured kinematic region. Requiring a second jet in the event allowed a
more detailed comparison with QCD calculations. The measured dijet cross
sections are also compared to Monte Carlo (MC) models which incorporate
leading-order matrix elements followed by parton showers and hadronisation. The
NLO QCD predictions are in general agreement with the data although differences
have been isolated to regions where contributions from higher orders are
expected to be significant. The MC models give a better description than the
NLO predictions of the shape of the measured cross sections.


title:
Study of the X(3872) and Y(4260) in B0-->J/psi pi+ pi- K0 and B-->J/psi
  pi+ pi- K- decays

abstract:
  We present results of a search for the X(3872) in
B0-->X(3872)KS0,X(3872)-->J/psi pi+ pi-, improved measurements of
B-->X(3872)K-, and a study of the J/psi pi+ pi- mass region above the X(3872).
We use 232x106 B[overline B] pairs collected at the Upsilon(4S) resonance with
the BABAR detector at the PEP-II e+e- asymmetric-energy storage rings. The
results include the 90% confidence interval
1.34x10-6<BR(B0-->X(3872)K0,X-->J/psi pi+ pi-)<10.3x10-6 and the branching
fraction BR(B-->X(3872)K-,X-->J/psi pi+ pi-)=(10.1+-2.5+-1.0)x10-6. We observe
a (2.7+-1.3+-0.2)MeV/c2 mass difference of the X(3872) produced in the two
decay modes. Furthermore, we search for the Y(4260) in B decays and set the 95%
C.L. upper limit BR(B-->Y(4260)K-,Y(4260)-->J/psi pi+ pi-)<2.9x10-5.


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 D{\O}at Fermilab during {\RunI}
from 1992 to 1996 and {\RunII} since 2001, are summarized. The combination of
the published {\RunI} and preliminary {\RunII} results, taking correlated
uncertainties properly into account, is presented. The resulting preliminary
world average for the mass of the top quark is: $\MT=172.7\pm 2.9 \GeVc2$,
where the total error consists of a statistical part of $1.7 \GeVc2$ and a
systematic part of $2.4 \GeVc2$. Compared to the combination prepared for the
LP 2005 conference, this combination for the EPS-HEP 2005 conference includes
additional published {\RunI} and preliminary {\RunII} measurements.


title:
Search for psi(3770)\ra\rho\pi at the BESII detector at the Beijing
  Electron-Positron Collider

abstract:
  Non-$D\bar{D}$ decay $\psppto \rhopi$ is searched for using a data sample of
$(17.3\pm 0.5) pb^{-1}$ taken at the center-of-mass energy of 3.773 GeV by the
BESII detector at the BEPC. No $\rhopi$ signal is observed, and the upper limit
of the cross section is measured to be $\sigma(\EETO \rhopi)<6.0 pb$ at 90% C.
L. Considering the interference between the continuum amplitude and the $\pspp$
resonance amplitude, the branching fraction of $\pspp$ decays to $\rho\pi$ is
determined to be $\BR(\pspp\ra\rho\pi)\in(6.0\times10^{-6}, 2.4\times10^{-3})$
at 90% C. L. This is in agreement with the prediction of the $S$- and $D$-wave
mixing scheme of the charmonium states for solving the ``$\rhopi$ puzzle''
between $\jpsi$ and $\psp$ decays.

Neutral Pion Suppression at Forward Rapidities in d+Au Collisions at
  STAR

abstract:
  Measurements of the inclusive yields of pi0 mesons in p+p and d+Au collisions
at center of mass energy sqrt(s_NN)=200 GeV and pseudorapidity <eta>=4.00 (d
beam direction) are reported. The yield for p+p collisions is in general
agreement with perturbative QCD calculations. The d+Au yield is in agreement
with a calculation which models the Au nucleus as a Color Glass Condensate for
forward particle production. The nuclear modification factor derived from the
inclusive yields is qualitatively consistent with models which suppress the
gluon density in nuclei.


title: Dalitz Plot Study of B0 --> K+K-K0S Decays

abstract:
  We present a study of the dynamics in B0 --> K+ K- K0S decays with
approximately 230 million BBbar events collected by the BABAR detector at SLAC.
We find that the Dalitz plot distribution is best parameterized with the phi
K0S mode, an S-wave K+ K- resonance near 1500 MeV/c^2, and a large non-resonant
contribution. We set limits on resonances not included in our model, and study
models for the non-resonant contribution.

title: Observation of B^0 -> a_1^{+/-}(1260) \pi^{-/+}

abstract:
  We report a new measurement of the branching fraction of neutral $B$ meson
decays $B^0\ra a_{1}^{\pm}(1260)\pi^{\mp}$ with
\ensuremath{a_{1}^{\pm}(1260)\ra \rho^{0}\pi^{\pm}} and $\rho^0\ra pi^+\pi^-$
using $275\times 10^{6}$ BBar pairs collected by the Belle detector at the
KEKBasymmetric-energy $e^{+}e^{-}$ collider. We measure the branching fraction
$\mathcal{B}($B^0\ra a_{1}^{\pm}(1260)\pi^{\mp}=(48.6\pm 4.1(stat)\pm
3.9(syst)) \times 10^{-6}$. Using a relativistic Breit-Wigner parameterization,
we measure the mass and width of the $a_{1}(1260)$ to be $m_{a_1}=1197\pm 34
MeV/c^2$ and $\Gamma_{a_1}=305\pm 43 MeV/c^2$, respectively.


title: UNO

abstract:
  UNO (Underground Neutrino Observatory) is intended as a multi-purpose
detector, potentially useful for purposes which may not have been considered at
the time of its construction. UNO accomodates a comprehensive physics program,
encompassing nucleon decay and lepton flavor physics, including the possibility
of observing CP violation, grand unification scale physics, and detailed
observations of supernova explosions. The conceptual design of UNO is
described, along with specifics of how UNO would fit into an existing
commercial mine site in the western USA, which has been used as a strawman site
for planning and proposal development.


title: The deuteron structure function F2 with CLAS

abstract:
  The inclusive, inelastic eD scattering cross section has been measured with
the CLAS detector in Hall B of the Thomas Jefferson National Accelerator
Facility (TJNAF). Combining these data and previously measured world data we
have extracted Nachtmann moments of the deuteron structure function F2 in the
region 0.4 < Q2 < 100 GeV2/c2. These results are published in hep-ex/0506004.
The purpose of the present CLAS-Note is to tabulate the CLAS deuteron F2 data.
A description of the data analysis is reported in hep-ex/0506004.


title:
Model Independent Measurement of \swave $K^{-}\pi^{+}$ systems using
  $\Dp\to K\pi\pi$ Decays from Fermilab E791

abstract:
  A model-independent partial-wave analysis of the \swave component of the
$K\pi$ system from decays of $D^{+}$ mesons to the three-body $\Km\pip\pip$
final state is described. Data come from the Fermilab E791 experiment.
Amplitude measurements are made independently for ranges of $\Km\pip$ invariant
mass, and results are obtained below 825 \MeVcc, where previous measurements
exist only in two mass bins.
  This method of parametrizing a three-body decay amplitude represents a new
approach to analysing such decays. Though no model is required for the \swave,
a parametrization of the relatively well-known reference \pdash and \dwave s,
optimized to describe the data used, is required. In this paper, a Breit-Wigner
model is adopted to describe the resonances in these waves.
  The observed phase variation for the \sdash, \pdash and \dwave s do not match
existing measurements of $I=\half$ $\Km\pip$ scattering in the invariant mass
range in which scattering is predominantly elastic.
  If the data are mostly $I=\half$, this observation indicates that the Watson
theorem, which requires these phases to have the same dependence on invariant
mass, may not apply to these decays without allowing for some interaction with
the other pion.
  The production rate of $\Km\pip$ from these decays, if assumed to be
predominantly $I=\half$, is also found to have a significant dependence on
invariant mass in the region above 1.25 \GeVcc.
  These measurements can provide a relatively model-free basis for future
attempts to determine which strange scalar amplitudes contribute to the decays.


title: Experimental study of \etac decays into vector-vector final states

abstract:
  Using 58 million J/\psi events accumulated with the BES II detector,
branching fractions for the \eta_{c} ->VV decays, \eta_{c} -> \rho \rho,
\eta_{c} -> K^{*}{\bar K}^{*}, \eta_{c} -> \omega \omega, and \eta_{c} -> \phi
\phi, are measured. The branching fractions are Br(\eta_{c} -> \rho \rho) =
(1.25 \pm 0.37 \pm 0.51) \times 10^{-2}, Br(\eta_{c} -> \K^{*}{\bar K}^{*}) =
(10.4 \pm 2.6\pm 4.3) \times 10^{-3}, Br(\eta_{c} -> \omega\omega) < 6.3 \times
10^{-3} (90 % CL), and Br(\eta_{c} -> \phi \phi) = (2.5 \pm 0.5 \pm 0.9) \times
10^{-3}. The process \eta_{c} -> \omega\phi is also searched for, and the 90%
CL upper limit Br(eta_{c} -> \omega\phi) < 1.3 \times 10^{-3} is obtained for
this process.

Measurement of gamma in B-+ -> D(*) K-+ and B-+ -> D K*-+ decays with a
  Dalitz analysis of D -> Ks pi- pi+

abstract:
  We present a measurement of the Cabibbo-Kobayashi-Maskawa CP-violating phase
gamma with a Dalitz plot analysis of neutral D-meson decays to the Ks pi- pi+
final state from B-+ -> D(*) K-+ and B-+ -> D K*-+ decays, using a sample of
227 million BBbar pairs collected by the BaBar detector. We measure gamma = 67
+/- 28 +/- 13 +/- 11, where the first error is statistical, the second is the
experimental systematic uncertainty and the third reflects the Dalitz model
uncertainty. This result suffers from a two-fold ambiguity. The contribution to
the Dalitz model uncertainty due to the description of the pipi S-wave in D0 ->
Ks pi- pi+, evaluated using a K-matrix formalism, is found to be 3 degrees.


title: D0 Top Quark Results and their Dependence on Successful Grid Computing

abstract:
  The heaviest known Fermion particle -- the top quark -- was discovered at
Fermilab in the first run of the Tevatron in 1995. However, besides its mere
existence one needs to study its properties precisely in order to verify or
falsify the predictions of the Standard Model. With the top quark's extremely
high mass and short lifetime such measurements probe yet unexplored regions of
the theory and bring us closer to solving the open fundamental questions of our
universe of elementary particles such as why three families of quarks and
leptons exist and why their masses differ so dramatically.
  To perform these measurements hundreds of millions of recorded
proton-antiproton collisions must be reconstructed and filtered to extract the
few top quarks produced. Simulated background and signal events with full
detector response need to be generated and reconstructed to validate and
understand the results. Since the start of the second run of the Tevatron the
D0 collaboration has brought Grid computing to its aid for the production of
simulated events. Data processing on the Grid has recently been added and
thereby enabled us to effectively triple the amount of data available with the
highest quality reconstruction methods.
  We will present recent top quark results D0 obtained from these improved data
and explain how they benefited from the availability of computing resources on
the Grid.


title:
Search for $\Lambda_c^+ \to p K^+ \pi^-$ and $D_s^+ \to K^+ K^+ \pi^-$
  Using Genetic Programming Event Selection

abstract:
  We apply a genetic programming technique to search for the double Cabibbo
suppressed decays $\Lambda_c^+ \to p K^+ \pi^-$ and $D_s^+ \to K^+ K^+ \pi^-$.
We normalize these decays to their Cabibbo favored partners and find
$\text{BR}($\Lambda_c^+ \to p K^+ \pi^-$)/\text{BR}($\Lambda_c^+ \to p K^-
\pi^+$) = (0.05 \pm 0.26 \pm 0.02)%$ and $\text{BR}($D_s^+ \to K^+ K^+
\pi^-$)/\text{BR}($D_s^+ \to K^+ K^- \pi^+$) = (0.52\pm 0.17\pm 0.11)%$ where
the first errors are statistical and the second are systematic. Expressed as
90% confidence levels (CL), we find $< 0.46 % $ and $ < 0.78%$ respectively.
This is the first successful use of genetic programming in a high energy
physics data analysis.


title:
Search for New High Mass Particles Decaying to Lepton Pairs in pbarp
  Collisions at sqrt(s)=1.96 TeV

abstract:
  A search for new particles (X) that decay to electron or muon pairs has been
performed using approximately 200 pb**(-1) of pbarp collision data at
sqrt(s)=1.96 TeV collected by the CDF II experiment at the Fermilab Tevatron.
Limits on sigma(ppbar -> X)*BR(X -> ll) are presented as a function of dilepton
invariant mass m(ll) > 150 GeV/c**2, for different spin hypotheses (0, 1, or
2). The limits are approximately 25 fb for m(ll) > 600 GeV/c**2. Lower mass
bounds for X from representative models beyond the Standard Model including
heavy neutral gauge bosons are presented.


title:
Exotic narrow resonance searches in the systems $K_s^0 p$, $K_s^0
  \Lambda$ and $\Lambda p$ in pA-interactions at 10 GeV/c

abstract:
  Experimental data from the 2m propane bubble chamber have been analyzed to
search for an exotic baryon states, in the $K_s^0 p$, $K_s^0 \Lambda$ and
$\Lambda p$ decay mode for the reaction p+$C_3H_8$ at 10 GeV/c.
  The invariant mass spectrum $\Lambda K^0_s$ observe a narrow peaks at 1750,
1795,1850 MeV/$c^2$. The statistical significance of these peaks has been
estimated as 5.6, 3.3 and 3.0 S.D., respectively. There are the small
enhancements in mass regions of (1650-1675) and (1925-1950) MeV/c$^2$. These
would be candidates for the $N^0$ or the $\Xi^0$ pentaquark states.
  The $pK^0_s$ invariant mass spectrum shows resonant structures with $M_{K_s^0
p}$=1540, 1613, 1821 MeV/$c^2$. The statistical significance of these peaks
have been estimated as 5.5,4.8 and 5.0 s.d., respectively. There are also small
peaks in 1487(3 s.d.),1690(3.6 s.d.), 1750(2.3 s.d.) and 1980(3.0 s.d.)
MeV/$c^2$ mass regions.
  The invariant mass spectrum S=-1 $\Lambda p$ observe a narrow peaks at 2100,
2175,2285 and 2353 MeV/$c^2$. Their excess above background by the second
method is 6.9, 4.9, 3.8 and 2.9 S.D., respectively. There is also a small peak
in 2225(2.2 s.d.) MeV/$c^2$ mass region.

  We present recent analyses of top quark properties performed at Run II of the
Tevatron. Measurements of the top quark mass, branching ratios and W boson
helicity inside top quark decays are covered.

Experimental observation of optical rotation generated in vacuum by a
  magnetic field

abstract:
  We report the experimental observation of a light polarization rotation in
vacuum in the presence of a transverse magnetic field. Assuming that data
distribution is Gaussian, the average measured rotation is (3.9+/-0.5)e-12
rad/pass, at 5 T with 44000 passes through a 1m long magnet, with lambda = 1064
nm. The relevance of this result in terms of the existence of a light, neutral,
spin-zero particle is discussed.


title:
A Study of b --> c and b -->u Interference in the Decay B- --> [K+
  pi-]_D K*-

abstract:
  Using a sample of 232 x 10^6 Upsilon(4S)--> B B-bar events collected with the
BABAR detector at the PEP-II B-factory we study the decay B- --> [K+ pi-]_D K*-
where the K+ pi- is either from a Cabibbo-favored D0-bar decay or
doubly-suppressed D0 decay. We measure two observables that are sensitive to
the CKM angle gamma; the ratio R of the charge-averaged branching fractions for
the suppressed and favored decays; and the charge asymmetry A of the suppressed
decays: R=0.046 +/- 0.031(stat.) +/- 0.008(syst.) A=-0.22 +/- 0.61(stat.) +/-
0.17(syst.).


title:
Beam-Helicity Asymmetries in Double-Charged-Pion Photoproduction on the
  Proton

abstract:
  Beam-helicity asymmetries for the two-pion-photoproduction reaction gamma + p
--> p pi+ pi- have been studied for the first time in the resonance region for
center-of-mass energies between 1.35 GeV and 2.30 GeV. The experiment was
performed at Jefferson Lab with the CEBAF Large Acceptance Spectrometer using
circularly polarized tagged photons incident on an unpolarized hydrogen target.
Beam-helicity-dependent angular distributions of the final-state particles were
measured. The large cross-section asymmetries exhibit strong sensitivity to the
kinematics and dynamics of the reaction. The data are compared with the results
of various phenomenological model calculations, and show that these models
currently do not provide an adequate description for the behavior of this new
observable.


title: Summary of the Structure Functions and Low-x working group

abstract:
  We report a summary of the structure function working group which covers a
wide range of the recent results from HERA, Tevatron, RHIC, and JLab
experiments, and many theoretical issues from low x to high x.


title:
Measurements of the B -> X_s gamma Branching Fraction and Photon
  Spectrum from a Sum of Exclusive Final States

abstract:
  Using 88.9 million BB events collected by the BaBar detector at the Y(4S), we
measure the branching fraction for the radiative penguin process B -> X_s gamma
from the sum of 38 exclusive final states. The inclusive branching fraction
above a minimum photon energy E_gamma > 1.9 GeV is BF (b -> s gamma) = (3.27
+/- 0.18 (stat.) +0.55/-0.40 (syst.) +0.04/-0.09 (theory)) 10^-4. We also
measure the isospin asymmetry between B^- -> X_s ubar gamma and B^0bar -> X_s
dbar gamma to be Delta_0- = -0.006 +/- 0.058 (stat.) +/- 0.009 (syst.) +/-
0.024 (B^0bar / B^-). The photon energy spectrum is measured in the B rest
frame, from which moments are derived for different values of the minimum
photon energy. We present fits to the photon spectrum and moments which give
the heavy-quark parameters m_b and mu_pi^2. The fitted parameters are
consistent with those obtained from semileptonic B -> X_c l nu decays, and are
useful inputs for the extraction of Vub from measurements of semileptonic B ->
X_u l nu decays.


title:
Moments of the photon energy spectrum from $B\to X_s \gamma$ decays
  measured by Belle

abstract:
  We report preliminary measurements of the first (mean) and second moment
(variance) of the inclusive photon energy spectrum in $B\to X_s\gamma$ decays,
for threshold values of the photon energy in the range 1.8--2.3 GeV as measured
in the rest frame of the $B$-meson. These results are obtained from the Belle
measurement of the spectrum, which used a data set consisting of 152 million
$B\bar{B}$ pairs collected by the Belle detector at the KEKB asymmetric-energy
electron-positron collider operated on the $\Upsilon(4S)$ resonance.


title: Heavy Hyperon--Antihyperon Production

abstract:
  Based on the experience from the production of anti-Lambda Lambda and
anti-Sigma Sigma pairs at LEAR (experiment PS185) it is suggested to continue
the investigations towards the heavier antihyperon--hyperon pairs anti-Xi Xi
and anti-Omega Omega in view of: (1) the production dynamics of the heavier
antihyperon--hyperon out of the anti-p p annihilation (2) a comparison of the
(3s 3anti-s quark system) anti-Omega Omega to the (3 (anti-s s)) 3 phi meson
production, where both systems have similar masses (3.345 and 3.057,
respectively) and identical valence quark content. A systematic study of the
antihyperon--hyperon production with increasing strangeness content is
interesting for the following reasons: The anti-Omega Omega production is the
creation of two spin 3/2 objects out of the two spin 1/2 anti-p p particles.
Results of the PS185 experiments prove a clear dominance of the spin triplet
anti-s s dissociation. In the Omega anti-Omega the three s-quarks (three anti-s
quarks) are aligned to spin 3/2 each. If the three anti-s s pairs are now all
in spin triplet configurations when created out of the gluonic interaction they
should have spin parity quantum number as 3^- as long as Omega anti-Omega is
created with relative L=0 angular momentum. The comparison of the Omega
anti-Omega baryon pair to the phi phi phi three meson production (where the
three anti-s s quark pairs might not but can be produced without relative
correlation) would provide a unique determination of the intermediate matter
state. Measurements of excitation functions and polarization transfers should
be used to examine these gluon rich anti-p p --> anti-Omega Omega and anti-p p
--> phi phi phi reaction channels. Such experiments should be performed at the
PANDA detector at the FAIR facility of the GSI.


title:
Measurement of Branching Fraction and Direct CP Asymmetry in B0-->rho0
  pi0 Decays

abstract:
  We report a measurement of the decay B0 --> rho0 pi0, using 386 x 10^6 BB-bar
pairs collected at the Upsilon(4S) resonance with the Belle detector at the
KEKB asymmetric-energy e+e- collider. We detect 51^{+14}_{-13} signal events
with a significance of 4.2 standard deviations, including systematic
uncertainties, and measure the branching fraction to be B(B0 --> rho0 pi0) =
(3.12^{+0.88}_{-0.82} (stat) +/- 0.33 (syst) ^{+0.50}_{-0.68} (model)) x
10^{-6}. We also perform the first measurement of direct CP violating asymmetry
in this mode.


title: Top Physics at ATLAS

abstract:
  The Large Hadron Collider LHC is a top quark factory: due to its high design
luminosity, LHC will produce about 200 millions of top quarks per year of
operation. The large amount of data will allow to study with great precision
the properties of the top quark, most notably cross-section, mass and spin. The
Top Physics Working Group has been set up at the ATLAS experiment, to evaluate
the precision reach of physics measurements in the top sector, and to study the
systematic effects of the ATLAS detector on such measurements. This reports
give an overview of the main activities of the ATLAS Top Physics Working Group
in 2004.

abstract:
  We report a measurement of the ratios of Wilson coefficients $A_9/A_7$ and
$A_{10}/A_7$ in $B \to K^* \ell^+ \ell^-$. The result is obtained from a data
sample containing 386 million $B\bar{B}$ pairs that was collected at the
$\Upsilon(4S)$ resonance with the Belle detector at the KEKB asymmetric energy
$e^+ e^-$ collider.


title:
A Measurement of the K0 Charge Radius and a CP Violating Asymmetry
  Together with a Search for CP Violating E1 Direct Photon Emission in the Rare
  Decay KL->pi+pi-e+e-

abstract:
  Using the complete KTeV data set of 5241 candidate KL->pi+pi-e+e- decays
(including an estimated background of 204+-14 events), we have measured the
coupling gCR=0.163+- 0.014(stat)+-0.023(syst) of the CP conserving charge
radius process and from it determined a K0 charge radius of
<r**2>(K0)=(-0.077+-0.007(stat)+-0.011(syst)) fm**2. We have also determined a
first experimental upper limit of 0.04 (90% CL) for the ratio |g_{E1}|/|g_{M1}|
of the coupling for the E1 direct photon emission process relative to the
coupling for M1 direct photon emission process. We also report the measurement
of its associated vector form factor |gM1`|(1+
(a_1/a_2)/(M(rho)**2-M(K)**2)+2M(K)E(gamma*)) where |gM1`|=(1.11+-
0.12(stat)+-0.08(syst) and a_1/a_2 = (-0.744+-0.027(stat)0.032(syst))
GeV**2/c**2. In addition, a measurement of the manifestly CP violating
asymmetry of magnitude (13.6+- 1.4+-(stat)+-1.5(syst))% in the CP and T odd
angle phi between the decay planes of the e+e- and pi+pi- pairs in the KL
center of mass system is reported.


title:
Observation of B- -> J/psi Lambda pbar and searches for B- -> J/psi
  Sigma0 pbar and B0 -> J/psi p pbar Decays

abstract:
  We report the observation of B- -> J/psi Lambda pbar and searches for B- ->
J/psi Sigma0 pbar and B0 -> J/psi p pbar decays, using a sample of 275 million
BBbar pairs collected with the Belle detector at the Upsilon(4S) resonance. We
observe a signal of 17.2 +/- 4.1 events with a significance of 11.1sigma and
obtain a branching fraction of B(B- -> J/psi Lambda pbar) = [11.6 +/- 2.8
(stat.) +1.8 -2.3(sys.)] x 10^-6. No signal is found for either of the two
decay modes, B- -> J/psi Sigma0 pbar and B0 -> J/psi p pbar, and upper limits
for the branching fractions are determined to be B(B- -> J/psi Sigma0 pbar) <
1.1 x 10^{-5} and B(B0 -> J/psi p pbar) < 8.3 x 10^{-7} at 90% confidence
level.


title: Search for Lepton Flavor Violation in the Decay tau -> electron gamma

abstract:
  A search for the non-conservation of lepton flavor in the decay tau ->
electron gamma has been performed with 2.07 x 10^8 e+e- -> tau+ tau- events
collected by the BABAR detector at the PEP-II storage ring at a center-of-mass
energy near 10.58 GeV. We find no evidence for a signal and set an upper limit
on the branching ratio of BR(tau -> electron gamma) < 1.1 x 10^-7 at 90%
confidence level.


title:
Measurements of Neutral B Decay Branching Fractions to K0S pi+ pi- Final
  States and the Charge Asymmetry of B0 --> K*+ pi-

abstract:
  We analyze the decay B0 -> K0s pi+ pi- using a sample of 232 million
Upsilon(4S) -> BB decays collected with the BaBar detector at the SLAC PEP-II
asymmetric-energy B factory. A maximum likelihood fit finds the following
branching fractions: BF(B0 -> K0 pi+ pi-) = (43.0 +/- 2.3 +/- 2.3) x 10^{-6},
BF(B0 -> f0 (-> pi+ pi-) K0) = (5.5 +/- 0.7 +/- 0.5 +/- 0.3) x 10^{-6} and
BF(B0 -> K*+ pi-) = (11.0 +/- 1.5 +/- 0.5 +/- 0.5) x 10^{-6}. For these
results, the first uncertainty is statistical, the second is systematic, and
the third (if present) is due to the effect of interference from other
resonances. We also measure the CP-violating charge asymmetry in the decay B0
-> K*+ pi-, A(B0 -> K*+ pi-) = -0.11 +/- 0.14 +/- 0.05.


title:
Measurement of the Ratios of Branching Fractions B(Bs->Ds-
  pi+)/B(B0->D-pi+) and B(B+->D0bar pi+)/B(B0->D-pi+)

abstract:
  We report an observation of the decay Bs -> Ds- pi+ in p pbar collisions at
sqrt(s) = 1.96 TeV using 115 pb^(-1) of data collected by the CDF II detector
at the Fermilab Tevatron. We observe 83 +/- 11 Bs -> Ds- pi+ candidates,
representing a large increase in statistics over previous measurements and the
first observation of this decay at a p pbar collider. We present the first
measurement of the relative branching fraction B(Bs -> Ds- pi+) / B(B0 -> D-
pi+) = 1.32 +/- 0.18 (stat.) +/- 0.38 (syst.). We also measure B(B+ -> D0bar
pi+) / B(B0 -> D- pi+) = 1.97 +/- 0.10(stat.) +/- 0.21(syst.), which is
consistent with previous measurements.


title:
Observation of B+->Lambda_c+Lambda_c-K+ and B0->Lambda_c+Lambda_c^-K0
  decays

abstract:
  We report first measurements of the doubly charmed baryonic B decays
B->Lambda_c+Lambda_c-K. The B+->Lambda_c+Lambda_c-K+ decay is observed with a
branching fraction of (6.5+1.0-0.9+-1.1+-3.4)x10^{-4} and a statistical
significance of 15.4sigma. The B0->Lambda_c+Lambda_c-K0 decay is observed with
a branching fraction of (7.9+2.9-2.3+-1.2+-4.2)x10^{-4} and a statistical
significance of 6.6sigma. The branching fraction errors are statistical,
systematic, and the error resulting from the uncertainty of Lambda_c+->pK-pi+
decay branching fraction. The analysis is based on 357fb-1 of data accumulated
at the Y(4S) resonance with the Belle detector at the KEKB asymmetric e+e-
collider.


title: Electroweak Measurements at CDF

abstract:
  We present some recent measurements on electroweak physics using data
collected by the CDF experiment at the Tevatron proton anti-proton collider
($\sqrt{s}=1.96\mathrm{TeV}$) at Fermilab (Batavia, Ill, USA).


title: Measurement of CP Asymmetries in B0-> KS pi0 pi0 Decays

abstract:
  We present a preliminary measurement of the time-dependent CP asymmetry for
the neutral B-meson decay into the CP = +1 final state KS pi0 pi0, with KS->
pi+ pi- and pi0-> gamma gamma. We use a sample of approximately 227 million
B-meson pairs recorded at the Y(4S) resonance by the BaBar detector at the
PEP-II B-Factory at SLAC. From a maximum likelihood fit we extract the
mixing-induced CP-violation parameter S = 0.84 +/- 0.71(stat} +/- 0.08{syst)
and the direct CP-violation parameter C = 0.27 +/- 0.52(stat) +/- 0.13(syst},
where the first uncertainty is statistical and the second systematic.


title:
Measurement of Exclusive $B \to X_u \ell \nu$ Decays with $D^{(*)} \ell
  \nu$ Decay Tagging

abstract:
  We report a measurement of the charmless semileptonic decays $B^0 \to \pi^- /
\rho^- \ell^{+} \nu$ and $B^+ \to \pi^0 / \rho^0 \ell^{+} \nu$, based on 253
fb$^{-1}$ of data collected with the Belle detector at the KEKB $e^+e^-$
asymmetric collider. In this analysis, the accompanying $B$ meson is
reconstructed in the semileptonic mode $B \to D^{(*)} \ell \nu$, enabling
detection of the signal modes with high purity. We measure the branching
fractions ${\cal B}(B^0 \to \pi^- \ell^+ \nu) = (1.48\pm 0.20\pm 0.16\pm 0.04)
\times 10^{-4}$, ${\cal B}(B^0 \to \rho^- \ell^+ \nu) = (2.07\pm 0.47\pm
0.25\pm 0.14) \times 10^{-4}$, ${\cal B}(B^+ \to \pi^0 \ell^+ \nu) = (0.76\pm
0.13\pm 0.08\pm 0.04) \times 10^{-4}$ and ${\cal B}(B^+ \to \rho^0 \ell^+ \nu)
= (1.39\pm 0.23\pm 0.17\pm 0.03) \times 10^{-4}$, where the errors are
statistical, experimental systematic, and systematic due to form-factor
uncertainties, respectively. For each mode we also present the partial
branching fractions in three $q^2$ intervals; $q^2 < 8$, $8 \leq q^2 < 16$, and
$q^2 \geq 16$ GeV$^2/c^2$. Based on these results, the magnitude of the
Cabibbo-Kobayashi-Maskawa matrix element $V_{ub}$ is extracted. All of the
presented results are preliminary.


title:
Measurement of charm fragmentation ratios and fractions in
  photoproduction at HERA

abstract:
  The production of D^*+, D^0, D^+, D_s^+ and Lambda_c^+ charm hadrons and
their antiparticles in ep scattering at HERA was measured with the ZEUS
detector using an integrated luminosity of 79 pb^-1. The measurement has been
performed in the photoproduction regime with the exchanged-photon virtuality
Q^2 < 1 GeV^2 and for photon-proton centre-of-mass energies in the range 130 <
W < 300 GeV. The charm hadrons were reconstructed in the range of transverse
momentum p_T(D, Lambda_c) > 3.8 GeV and pseudorapidity |eta(D, Lambda_c)| <
1.6. The production cross sections were used to determine the ratio of neutral
and charged D-meson production rates, R_u/d, the strangeness-suppression
factor, gamma_s, and the fraction of charged D mesons produced in a vector
state, P_v^d. The measured R_u/d and gamma_s values agree with those obtained
in deep inelastic scattering and in e^+e^- annihilations. The measured P_v^d
value is smaller than, but consistent with, the previous measurements. The
fractions of c quarks hadronising as a particular charm hadron, f(c -> D,
Lambda_c), were derived in the given kinematic range. The measured open-charm
fragmentation fractions are consistent with previous results, although the
measured f(c -> D^*+) is smaller and f(c -> Lambda_c^+) is larger than those
obtained in e^+e^- annihilations. These results generally support the
hypothesis that fragmentation proceeds independently of the hard sub-process.


title: A Review of Tev Scale Lepton-Hadron and Photon-Hadron Colliders

abstract:
  The investigation of lepton-hadron and photon-hadron collisions at TeV scale
is crucial both to clarify the strong interaction dynamics from nuclei to
quark-parton level and for adequate interpretation of experimental data from
future hadron colliders (LHC and VLHC). In this presentation different TeV
scale lepton-hadron and photon-hadron collider proposals (such as THERA,
LEP-LHC, QCD Explorer etc) are discussed. The advantages of linac-ring type
colliders has been shown comparatively.


title:
Main Parameters of Ilc-Tevatron Based Lepton-Hadron and Photon-Hadron
  Colliders

abstract:
  The construction of the ILC tangential to Tevatron ring will give opportunity
to investigate electron-proton, positron-proton, electron-antiproton,
positron-antiproton interactions at 1 TeV center of mass energy. The analysis
of the lepton-hadron collisions in these energy region is very important both
for understanding of strong interaction dynamics and for adequate
interpretation of future LHC and VLHC data. In addition, ILC-Tevatron collider
will provide a possibility to realize photon-hadron collisions in the same
energy region using Compton backscattered laser photon off ILC electron beam.
Main parameters of these colliders are estimated and their physics search
potential is briefly discussed.


title:
Measurement of $b$ hadron masses in exclusive $J/\psi$ decays with the
  CDF detector

abstract:
  We measure the masses of $b$ hadrons in exclusively reconstructed final
states containing a $J/\psi\to\mu^-\mu^+$ decay using $\rm 220 pb^{-1}$ of data
collected by the CDF II experiment. We find: m(B^+) = 5279.10 \pm
0.41_{(stat.)} \pm 0.36_{(sys.)} MeVcc, m(B^0) = 5279.63 \pm 0.53_{(stat.)} \pm
0.33_{(sys.)} MeVcc, m(B^0_s) = 5366.01 \pm 0.73_{(stat.)} \pm 0.33_{(sys.)}
MeVcc, m(\Lambda^0_b) = 5619.7 \pm 1.2_{(stat.)} \pm 1.2_{(sys.)} MeVcc. m(B^+)
- m(B^0) = -0.53 \pm 0.67_{(stat.)} \pm 0.14_{(sys.)} MeVcc, m(B^0_s) - m(B^0)
= 86.38 \pm 0.90_{(stat.)} \pm 0.06_{(sys.)} MeVcc m(\Lambda^0_b) - m(B^0) =
339.2 \pm 1.4_{(stat.)} \pm 0.1_{(sys.)} MeVcc. The measurements of the
$B^0_s$, $\Lambda^0_b$ mass, $m(B^0_s)-m(B^0)$ and $m(\Lambda^0_b)-m(B^0)$ mass
difference are of better precision than the current world averages.

  We observe signals for the decays psi(3770)--> X J/psi from data acquired
with the CLEO detector operating at the CESR e^+e^- collider with sqrt{s}=3773
MeV. We measure the following branching fractions B(psi(3770)--> XJ/psi) and
significances: (189 +- 20 +- 20) x 10^-5 (11.6sigma) for X=pi^+pi^-, (80 +- 25
+- 16) x 10^-5 (3.4sigma) for X=pi^0pi^0, and (87 +- 33 +- 22) x 10^-5
(3.5sigma) for X=eta, where the errors are statistical and systematic,
respectively. The radiative return process e^+e^- -->gamma psi(2S) populates
the same event sample and is used to measure Gamma_{ee}[psi(2S)]=(2.54 +- 0.03
+- 0.11) keV.

weak phases from $B \to D K$ decays.


title:
Observation of a resonance X(1835) in J/\psi --> \gamma \pi^+ \pi^-
  \eta^{\prime}

abstract:
  The decay channel J/\psi --> \gamma \pi^+ \pi^- \eta^{\prime} is analyzed
using a sample of 5.8\times 10^7 J\psi events collected with the BESII
detector. A resonance, the X(1835), is observed in the \pi^+ \pi^-
\eta^{\prime} invariant mass spectrum with a statistical significance of 7.7
\sigma. A fit with a Breit-Wigner function yields a mass M = 1833.7 \pm
6.1(stat) \pm 2.7(syst) MeV/c^2, a width \Gamma = 67.7 \pm 20.3(stat) \pm
7.7(syst) MeV/c^2 and a product branching fraction B(J/\psi --> \gamma X) B(X
--> \pi^+ \pi^- \eta^{\prime}) = (2.2 \pm 0.4(stat) \pm 0.4(syst)) \times
10^{-4}. The mass and width of the X(1835) are not compatible with any known
meson resonance. Its properties are consistent with expectations for the state
that produces the strong p\bar{p} mass threshold enhancement observed in the
J\psi -->\gamma p \bar{p} process at BESII.


title:
Efficient propagation of the polarization from laser photons to
  positrons through Compton scattering and electron-positron pair creation

abstract:
  We demonstrated for the first time the production of highly polarized
short-pulse positrons with a finite energy spread in accordance with a new
scheme that consists of two-quantum processes, such as inverse Compton
scatterings and electron-positron pair creations. Using a circularly polarized
laser beam of 532 nm scattered off a high-quality electron beam with the energy
of 1.28 GeV, we obtained polarized positrons with an intensity of 10^4
e+/bunch. Magnitude of positron polarizations was determined as 73+-15(sta)
+-19(sys)% by means of a newly designed positron polarimeter.

Measurements of the Absolute Branching Ratios for the Dominant KL
  Decays, the KL Lifetime, and Vus with the KLOE Detector

abstract:
  From a sample of about 10^9 Phi mesons produced at DAFNE, we have selected KL
mesons tagged by observing KS->pi+pi- decays. We present results on the major
KL branching ratios, including those of the semileptonic decays needed for the
determination of Vus. These branching ratio measurements are fully inclusive
with respect to final-state radiation. The KL lifetime has also been measured.

title:
Measurements of Inclusive W and Z Cross Sections in p-pbar Collisions at
  sqrt{s} =1.96 TeV

abstract:
  We report the first measurements of inclusive W and Z boson cross sections
times the corresponding leptonic branching ratios for p pbar collisions at
sqrt{s} = 1.96 TeV based on the decays of the W and Z bosons into electrons and
muons. The data were recorded with the CDF II detector at the Fermilab Tevatron
and correspond to an integrated luminosity of 72.0 +/- 4.3 pb-1. We test e-mu
lepton universality in W decays by measuring the ratio of the W->mu nu to W->e
nu cross sections and determine a value of 0.991 +/- 0.004(stat.) +/-
0.011(syst.) for the ratio of W-l-nu couplings (g_mu/g_e). Since there is no
sign of non-universality, we combine our cross section measurements in the
different lepton decay modes and obtain sigma*BR(W->lnu) = 2.749 +/-
0.010(stat.) +/- 0.053(syst.) +/- 0.165(lum.) nb and
sigma*BR(gamma*/Z->ll)=254.9 +/- 3.3(stat.) +/- 4.6(syst.) +/- 15.2(lum.) pb
for dilepton pairs in the mass range between 66 GeV/c^2 and 116 GeV/c^2. We
compute the ratio R of the W->lnu to Z->ll cross sections taking all
correlations among channels into account and obtain R=10.84 +/- 0.15(stat.) +/-
0.14(syst.) including a correction for the virtual photon exchange component in
our measured gamma*/Z->ll cross section. Based on the measured value of R, we
extract values for the W leptonic branching ratio, BR(W->lnu) =0.1082 +/-
0.0022; the total width of the W boson, Gamma(W) =2092 +/- 42 MeV; and the
ratio of W and Z boson total widths, Gamma(W)/Gamma(Z) = 0.838 +/- 0.017. In
addition, we use our extracted value of Gamma(W) whose value depends on various
electroweak parameters and certain CKM matrix elements to constrain the V_CS
CKM matrix element, |V_CS| = 0.976 +/- 0.030.


title:
Improved Measurements of Branching Fractions and CP Asymmetries in B->
  eta h Decays

abstract:
  We report improved measurements of B decays with an eta meson in the final
state using 357 fb^-1 of data collected by the Belle detector at the KEKB e^+
e^- collider. We observe the decays B^+- ->eta pi^+- and B^+- -> eta K^+-; the
measured branching fractions are Br(B^+- -> eta pi^+-) = (3.9 +-
0.5(stat.)+-0.2(sys.))*10^-6 and Br(B^+- -> eta K^+-) =
(2.2+-0.4(stat.)+-0.1(sys.))*10^-6, respectively. Their corresponding
CP-violating asymmetries are measured to be -0.10+-0.11(stat.)+-0.02(sys.) for
eta pi^+- and -0.55+-0.19(stat.)+0.04-0.03(sys.) for eta K^+-. No significant
signal is found for B^0-> eta K^0 decays; the upper limit on the branching
fraction at the 90% confidence level is Br(B^0->eta K^0) < 1.9*10^-6.


title: Search for Rare and Forbidden Decays D^+ --> h^pm e^mp e^+

abstract:
  Using 0.8 million D^+D^- pairs collected with the CLEO-c detector at the
psi(3770) resonance, we have searched for flavor-changing neutral current and
lepton-number-violating decays of D^+ mesons to final states with dielectrons.
We find no indication of either, obtaining 90% confidence level upper limits of
B(D^+ -> \pi^+ e^+ e^-) < 7.4 X 10^{-6}$, B(D^+ -> \pi^- e^+ e^+) < 3.6 X
10^{-6}$, B(D^+ -> K^+ e^+ e^-) < 6.2 X 10^{-6}$, and B(D^+ -> K^- e^+ e^+) <
4.5 X 10^{-6}$.


title:
Measurement of Branching Fractions for $B\to {\chi}_{c1(2)} K (K^*)$ at
  Belle

abstract:
  We have measured the branching fractions for the exclusive decay modes $B\to
{\chi}_{c1(2)} K(K^*)$ using a $140~{\rm fb}^{-1}$ data sample collected by the
Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider. The measured
branching fractions for $B^+\to {\chi}_{c1}K^+$, $B^0\to {\chi}_{c1}K^0$,
$B^0\to {\chi}_{c1}K^{*0}$ and $B^+\to {\chi}_{c1}K^{*+}$ decay modes are
$(4.5\pm 0.2\pm0.5)\times 10^{-4}$, $(3.5\pm 0.3\pm0.5)\times 10^{-4}$,
$(3.1\pm 0.3\pm0.7)\times 10^{-4}$ and $(4.1\pm 0.6\pm0.9)\times 10^{-4}$,
respectively, where the first error is statistical and the second error is
systematic. We do not observe statistically significant signals for the $B\to
{\chi}_{c2}K(K^*)$ decay modes and set upper limits at the 90% confidence
level. We also study the helicity distribution for $B\to {\chi}_{c1} K^*$ decay
mode and show that the longitudinal polarization component is dominant. {{\it

title: Angles of the CKM Unitarity Triangle Measured at Belle

abstract:
  The Belle experiment has used several methods to measure or constrain the
angles phi_1, phi_2, and phi_3 (or beta, alpha, and gamma) of the CKM unitarity
triangle. The results are sin(2phi_1) = 0.728 \pm 0.056 (stat) \pm 0.023 (syst)
or phi_1= (23.4 +2.7 -2.4) degrees from B0 -> J/psi K0 decays (140 fb-1); phi_2
= 0-19 degrees or 71-180 degrees at 95.4% CL from B0 -> pi+pi- decays (253
fb-1); and phi_3 = [68 +14 -15 (stat) \pm 13 (syst) \pm 11 (model)] degrees
from B+ -> (D0, D0bar) K+, (D0,D0bar) -> K0_S pi+ pi- decays (253 fb-1). These
values satisfy the triangle relation phi_1 + phi_2 + phi_3 = 180 degrees within
their uncertainties. The angle phi_1 is also determined from several b -> s
qbar q penguin-dominated decay modes; the value obtained by taking a weighted
average of the individual results differs from the B0 -> J/psi K0 result by
more than two standard deviations. The angle phi_2 is constrained by measuring
a CP asymmetry in the decay time distribution; the asymmetry observed is large,
and the difference in the yields of B0,B0bar -> pi+ pi- decays constitutes the
first evidence for direct CP violation in the B system.

Single Electrons from Heavy Flavor Decays in p+p Collisions at sqrt(s) =
  200 GeV

abstract:
  The invariant differential cross section for inclusive electron production in
p+p collisions at sqrt(s) = 200 GeV has been measured by the PHENIX experiment
at the Relativistic Heavy Ion Collider over the transverse momentum range $0.4
<= p_T <= 5.0 GeV/c at midrapidity (eta <= 0.35). The contribution to the
inclusive electron spectrum from semileptonic decays of hadrons carrying heavy
flavor, i.e. charm quarks or, at high p_T, bottom quarks, is determined via
three independent methods. The resulting electron spectrum from heavy flavor
decays is compared to recent leading and next-to-leading order perturbative QCD
calculations. The total cross section of charm quark-antiquark pair production
is determined as sigma_(c c^bar) = 0.92 +/- 0.15 (stat.) +- 0.54 (sys.) mb.


title: Dynamical Likelihood Method for Reconstruction of Quantum Process

abstract:
  The dynamical likelihood method for analysis of high energy collider events
is reformulated. The method is to reconstruct the elementary parton state from
observed quantities. The basic assumption is that each of final state partons
occupies a unit phase space. The parton kinematics is statistically
reconstructed using (a) virtual masses of resonant partons and (b) parton
kinematic quantities inferred from observed quantities. Generation of (b) is
made with the transfer function which is the probability function for parton
kinematics from a given set of observables. Corresponding to the unit parton
phase space, the transfer variable spaces are also quantized. The likelihood of
the reconstructed state is defined by the Poisson probability for a single
event with the expected number of event that is the cross section per unit
phase space times a luminosity factor. Applications of the method to selection
of process, parton-observable identification, determinations of parton
kinematics and dynamical parameters are discussed.


title:
Search for Bs -> mu+mu- and Bd -> mu+mu- Decays in ppbar Collisions with
  CDF II

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 364 pb-1 of data collected by the CDF II
detector at the Fermilab Tevatron Collider. After applying all selection
requirements, we observe no candidates inside the Bs or Bd mass windows,
consistent with the background expectation. The resulting upper limits on the
branching fractions are B(Bs -> mu+mu-) < 1.5E10-7 and B(Bd -> mu+mu-) < 3.9E-8
at 90% confidence level.


title: Observation of the ^1P_1 State of Charmonium

abstract:
  The spin-singlet P-wave state of charmonium, hc(1P1), has been observed in
the decay psi(2S) -> pi0 hc followed by hc -> gamma etac. Inclusive and
exclusive analyses of the M(hc) spectrum have been performed. Two complementary
inclusive analyses select either a range of energies for the photon emitted in
hc -> gamma etac or a range of values of M(etac). These analyses, consistent
with one another within statistics, yield M(h_c) =[3524.9 +/- 0.7 (stat) +/-
0.4 (sys)]MeV/c^2 and a product of the branching ratios B_psi(psi(2S) -> pi0
hc) x B_h(hc -> gamma etac) = [3.5 +/- 1.0 (stat) +/- 0.7 (sys)] x 10^{-4}.
When the etac is reconstructed in seven exclusive decay modes, 17.5 +/- 4.5 hc
events are seen with an average mass M(hc) = [3523.6 +/- 0.9 (stat) +/- 0.5
(sys)] MeV/c^2, and B_psi x B_h = [5.3 +/- 1.5 (stat) +/- 1.0 (sys)] x 10^{-4}.
Because the inclusive and exclusive data samples are largely independent they
are combined to yield an overall mass M(hc) = [3524.4 +/- 0.6 (stat) +/- 0.4
(sys)]MeV/c^2 and product of branching ratios B_psi x B_h = [4.0 +/- 0.8 (stat)
+/- 0.7 (sys)] x 10^{-4}. The hc mass implies a P-wave hyperfine splitting
Delta M_{HF}(1P) \equiv M(1^3P)-M(1^1P_1) = [1.0 +/- 0.6 (stat) +/- 0.4 (sys)]
MeV/c^2.


title: Heavy quark production at HERA and the LHC

abstract:
  Measurements of heavy quark production, particularly from HERA, their
theoretical understanding and their relevance for the LHC are reviewed. The
status of beauty and charm production is discussed in the context of the
different components of the production process: the parton density function of
the colliding hadrons; the hard scatter; and the fragmentation of the quarks
into hadrons. The theory of QCD at next-to-leading order generally describes
well the hadronic structure and the production of heavy quarks although
sometimes fails in details which are highlighted. The fragmentation of heavy
quarks measured at HERA is consistent with that at LEP and hence supports the
notion of universality.


title:
Measurement of the Branching Ratios Gamma(D_s*+ -> D_s+ pi0)/Gamma(D_s*+
  -> D_s+ gamma) and Gamma(D0+ -> D0 pi0)/Gamma(D0* -> D0 gamma)

abstract:
  Data samples corresponding to the isospin-violating decay $D_s^{*+}\to D_s^+
\pi^0$ and the decays $D_s^{*+}\to D_s^+\gamma$, $D^{*0}\to D^0\pi^0$ and
$D^{*0}\to D^0\gamma$ are reconstructed using 90.4 ${\rm fb}^{-1}$ of data
recorded by the BaBar detector at the PEP-II asymmetric-energy $e^+e^-$
collider. The following branching ratios are extracted: $\Gamma(D_s^{*+}\to
D_s^+ \pi^0)/\Gamma(D_s^{*+}\to D_s^+\gamma) = 0.062\pm0.005 ({\rm
stat.})\pm0.006 ({\rm syst.})$ and $\Gamma(D^{*0}\to D^0\pi^0)/\Gamma(D^{*0}\to
D^0\gamma) = 1.74\pm0.02 ({\rm stat.})\pm0.13 ({\rm syst.})$. Both measurements
represent significant improvements over present world averages.


title:
Improved measurement of B0bar -> D_s^-D^+ and search for B0bar ->
  D_s^+D_s^- at Belle

abstract:
  We reconstruct B0bar -> D_s^-D^+ decays using a sample of 275 million BBbar
pairs recorded by the Belle experiment, and we measure the branching fraction
to be [7.42 +- 0.23(stat) +- 1.36(syst)] x 10^(-3). We also search for the
related decay B0bar -> D_s^+D_s^-. We observe no statistically significant
signal and set an upper limit on the branching fraction of 2.0 x 10^(-4) at 90%
C.L.


title: Search for exotic contributions to atmospheric neutrino oscillations

abstract:
  The energy spectrum of neutrino-induced upward-going muons in MACRO was
analysed in terms of relativity principles violating effects, keeping standard
mass-induced atmospheric neutrino oscillations as the dominant effect. The data
disfavor these possibilities even at a sub-dominant level; stringent 90% C.L.
limits are placed on the Lorentz invariance violation parameter $|\Delta v| < 6
\times 10^{-24}$ at $\sin 2{\theta}_v$ = 0 and $|\Delta v| < 2.5 \div 5 \times
10^{-26}$ at $\sin 2{\theta}_v$ = $\pm$1. The limits can be re-interpreted as
bounds on the Equivalence Principle violation parameters.

Fermilab accelerator complex, but external collaboration is emphasised.


title: Search for massive rare particles with the SLIM experiment

abstract:
  The search for magnetic monopoles in the cosmic radiation remains one of the
main aims of non-accelerator particle astrophysics. Experiments at high
altitude allow lower mass thresholds with respect to detectors at sea level or
underground. The SLIM experiment is a large array of nuclear track detectors at
the Chacaltaya High Altitude Laboratory (5290 m a.s.l.). The results from the
analysis of 171 m$^2$ exposed for more than 3.5 y are here reported. The
completion of the analysis of the whole detector will allow to set the lowest
flux upper limit for Magnetic Monopoles in the mass range 10$^5$ - 10$^{12}$
GeV. The experiment is also sensitive to SQM nuggets and Q-balls, which are
possible Dark Matter candidates.


title:
Search for Lepton and Baryon Number Violating tau- Decays into
  Lambda-bar pi- and Lambda pi-

abstract:
  We have searched for tau lepton decays, tau- -> Lambda-bar pi- and tau- ->
Lambda pi-, that simultaneously violate the conservation of the lepton and
baryon number using a data sample of 154 fb^{-1} collected with the Belle
detector at the KEKB e+e- asymmetric-energy collider. No evidence for a signal
was found in either of the decay modes and we set the following upper limits
for the branching fractions: B(tau^- -> Lambda-bar\pi-) < 1.4 * 10^{-7} and
B(tau^- -> Lambda pi^-) < 0.72 * 10^{-7} at the 90% confidence level. This is
the first search ever performed for these modes.

abstract:
  The poster presented the OPERA experiment and the SPL-Fr\'{e}jus neutrino
super beam project. OPERA (1) is an experiment willing to see tau neutrino
appearance. The detector is described in section 2 and the expected results are
given. Section 3 is devoted to the SPL neutrino super beam (2), which search
for $\theta\_{13}$. An optimisation of the SPL energy is proposed.


title:
Improved Measurements of Branching Fractions for B0 -> pi+pi-, K+pi-,
  and Search for K+K- at BaBar

abstract:
  We present preliminary measurements of branching fractions for the charmless
two-body decays B0 -> pi+pi- and K+pi-, and a search for B0 -> K+K- using a
data sample of approximately 227 million BBbar decays. Signal yields are
extracted with a multi-dimensional maximum likelihood fit, and the efficiency
is corrected for the effects of final-state radiation. We find the
charge-averaged branching fractions (in units of 10^{-6}): Br(B0 -> pi+pi-) =
5.5 +- 0.4 +- 0.3, Br(B0 -> K+pi-) = 19.2 +- 0.6 +- 0.6, Br(B0 -> K+K-) = <
0.40. The errors are statistical followed by systematic, and the upper limit on
K+K- represents a confidence level of 90%.


title:
First Evidence and Measurement of B_s^(*) barB_s^(*) Production at the
  Upsilon(5S)

abstract:
  We use data collected by the CLEO III detector at CESR on the Upsilon(5S)
resonance to measure the inclusive yield of Ds mesons. Comparing with data
taken on the Upsilon(4S), which decays into lighter B mesons, we make a model
dependent estimate of the ratio of Bs(*)anti-Bs(*) to the total b anti-b quark
pair production at the Upsilon(5S) energy of (16.0+/-2.6+/-5.8)%.


title:
Study of the Suppressed Decays $B^\pm \to [K^\mp \pi^\pm]_D K^\pm$ and
  $B^\pm \to [K^\mp \pi^\pm]_D \pi^\pm$ at Belle

abstract:
  We report an updated study of the suppressed decays $B^- \to [K^+\pi^-]_D
K^-$ and $B^- \to [K^+\pi^-]_D \pi^-$ where $[K^+\pi^-]_D$ indicates that the
$K^+\pi^-$ pair originates from a neutral $D$ meson. A data sample containing
386 million $B\bar{B}$ pairs recorded at the $\Upsilon(4S)$ resonance with the
Belle detector at the KEKB asymmetric $e^{+}e^{-}$ storage ring is used. This
decay mode is sensitive to the CKM angle $\phi_{3}$. We do not see a
significant signal for $B^- \to [K^+\pi^-]_{D} K^-$, and we set a limit on the
ratio of B decay amplitudes $r_B < 0.18$ at the 90% confidence level. We
measure the CP asymmetry of the $B^- \to [K^+\pi^-]_D \pi^-$ mode, ${\cal
A}_{D\pi} = 0.10 \pm 0.22 (stat) \pm 0.02 (syst)$.


title: Multi-Lepton Events at H1 and Search for Doubly-Charged Higgs Bosons

abstract:
  Events with two or more leptons (electrons or muons) with high transverse
momentum are measured in electron-proton collisions at HERA using the data
sample collected in the period 1994-2005. Multi-lepton events at high
transverse momenta are of special interest as these signature might reveal new
physics beyond the Standard Model. An example is the single production of
doubly-charged Higgs bosons $H^{\pm \pm}_{L,R}$, which couple to leptons of the
$i^\prime$th and $j^\prime$th generation via Yukawa couplings $h^{L,R}_{ij}$.
Results from a search for doubly-charged Higgs bosons in the decays into
electrons, muons and taus are presented using data taken in the period
1994-2000. No evidence for doubly-charged Higgs production is found and we
derive limits on the $h_{ee}^{L,R}$ and $h_{e \mu}^{L,R}$ Yukawa couplings as a
function of the $H^{\pm\pm}_{L,R}$ mass.


title: Partial Wave Analysis of $\chi_{c0}\to\pi^+\pi^-K^+K^-$

abstract:
  A partial wave analysis of $\chi_{c0}\to\pi^+\pi^-K^+K^-$ in
$\psi(2S)\to\gamma\chi_{c0}$ decay is presented using a sample of 14 million
$\psi(2S)$ events accumulated by the BES II detector. The data are fitted to
the sum of relativistic covariant tensor amplitudes for intermediate resonant
decay modes. From the fit, significant contributions to $\chi_{c0}$ decays from
the channels $f_0(980)f_0(980)$, $f_0(980)f_0(2200)$, $f_0(1370)f_0(1710)$,
$K^*(892)^0\bar K^*(892)^0$, $K^*_0(1430)\bar K^*_0(1430)$, $K^*_0(1430)\bar
K^*_2(1430) + c.c.$, and $K_1(1270)K$ are found. Flavor-SU(3)-violating
$K_1(1270)-K_1(1400)$ asymmetry is observed. Values obtained for the masses and
widths of the resonances $f_0(1710)$, $f_0(2200)$, $f_0(1370)$, and
$K^*_0(1430)$ are presented.
