First Observation of Upsilon(3S) --> tau tau and Tests of Lepton
  Universality in Upsilon Decays

abstract:
  Using data collected with the CLEO-III detector at the CESR e+e- collider, we
report on a first observation of the decay of the Upsilon(3S) to tau tau, and
precisely measure the ratio of branching fractions of Upsilon(nS),n=1,2,3 to
tau tau and mu mu final states, finding agreement with expectations from lepton
universality. We derive absolute branching fractions for these decays, and also
set a limit on the influence of a low mass CP-odd Higgs boson in the decay of
the Upsilon(1S).


title: New H1 results on isolated leptons and missing pt at HERA

abstract:
  The search for events containing isolated leptons (electrons or muons) and
missing transverse momentum produced in $e^{\pm}p$ collisions is performed with
the H1 detector at HERA in the period 1994--2005. The analysed data sample
corresponds to an integrated luminosity of 279 pb$^{-1}$, which includes 53
pb$^{-1}$ of $e^{+}p$ data and 107 pb$^{-1}$ of $e^{-}p$ data from the new
HERA~II phase. A total of 40 events are observed in the data, compared to a
Standard Model (SM) prediction of 34.3 $\pm$ 4.8. At large hadronic transverse
momentum $P_{T}^{X} >$ 25 GeV, a total of 17 events are observed compared to
9.0 $\pm$ 1.5 predicted by the SM. In this region, 15 events are observed in
the $e^{+}p$ data compared to a SM prediction of 4.6 $\pm$ 0.8, whereas in the
$e^{-}p$ data 2 events are observed compared to a SM prediction of 4.4 $\pm$
0.7.


title:
Observation of Bs->K+K- and Measurements of Branching Fractions of
  Charmless Two-body Decays of B0 and Bs Mesons in p-pbar Collisions at
  sqrt(s)=1.96 TeV

abstract:
  We search for decays of the type B0(Bs)->h+h'- (where h,h'= K or pi) in 180
pb-1 of p-pbar collisions collected at the Tevatron by the upgraded Collider
Detector at Fermilab. We report the first observation of the new mode Bs->K+K-
with a yield of 236 +- 32 events, corresponding to
(f_s/f_d)*BR(Bs->K+K-)/BR(B0->K+pi-) = 0.46+-0.08(stat.)+-0.07(syst.), where
f_s/f_d is the ratio of production fractions of Bs and B0. We find results in
agreement with world averages for the B0 modes, and set the following new
limits at 90% CL: BR(Bs->K-pi+) < 5.6*10^{-6} and BR(Bs->pi+pi-) < 1.7*10^{-6}.


title:
Search for the Standard Model Higgs Boson in the ZH -->
  neutrino-neutrino-b-b channel

abstract:
  We report a search for the standard model (SM) Higgs boson based on data
collected by the D0 experiment at the Fermilab Tevatron Collider, corresponding
to an integrated luminosity of 260 pb^-1. We study events with missing
transverse energy and two acoplanar b-jets, which provide sensitivity to the ZH
production cross section in the neutrino-neutrino-b-b channel and to WH
production, when the lepton from the W -> lepton+neutrino decay is undetected.
The data are consistent with the SM background expectation, and we set 95% C.L.
upper limits on sigma(p p-bar -> ZH/WH) x B(H -> b b-bar) from 3.4/8.3 to
2.5/6.3 pb, for Higgs masses between 105 and 135 GeV.


title:
Measurements of $\psip$ decays into $\gamma K\bar{K}\pi$ and
  $\gamma\eta\pipi$

abstract:
  Radiative decays of the $\psip$ into $\gamma K\bar{K}\pi$ and
$\gamma\eta\pipi$ final states are studied using 14 million $\psip$ events
collected with the BESII detector. Branching fractions or upper limits on the
branching fractions of $\psip$ and $\xcj$ decays are reported. No significant
signal for $\etafl/\etafh$ is observed in the $K\bar{K}\pi$ or $\eta\pipi$ mass
spectra, and upper limits on the branching fractions of $\psip\rar\gamma\etaf$,
$\etaf\rar K\bar{K}\pi$ and $\eta\pipi$ are determined.


title: Neutrino physics at accelerators

abstract:
  Present and future neutrino experiments at accelerators are mainly concerned
with understanding the neutrino oscillation phenomenon and its implications.
Here a brief account of neutrino oscillations is given together with a
description of the supporting data. Some current and planned accelerator
neutrino experiments are also explained.


title: Measurement of \chi_cJ--> K+K-K+K-

abstract:
  Using 14M psi(2S) events taken with the BES-II detector, chi_cJ-->K+K-K+K-
decays are studied. For the four-kaon final state, the branching fractions are
B(chi_c0,1,2 -->K+K-K+K-)=(3.48\pm 0.23\pm 0.47)\times 10^{-3}, (0.70\pm
0.13\pm 0.10)\times 10^{-3}, and (2.17\pm 0.20\pm 0.31)\times 10^{-3}. For the
\phi K+K- final state, the branching fractions, which are measured for the
first time, are B(chi_c0,1,2-->\phi K+K-)=(1.03\pm 0.22\pm 0.15)\times 10^{-3},
(0.46\pm 0.16\pm 0.06)\times 10^{-3}, and (1.67\pm 0.26\pm 0.24)\times 10^{-4}.
For the \phi\phi final state, B(chi_{c0,2}-->\phi\phi)=(0.94\pm 0.21\pm
0.13)\times 10^{-3} and (1.70\pm 0.30\pm 0.25)\times 10^{-3}.


title: MEMPHYS:A large scale water Cerenkov detector at Fr\'ejus

abstract:
  A water \v{C}erenkov detector project, of megaton scale, to be installed in
the Fr\'ejus underground site and dedicated to nucleon decay, neutrinos from
supernovae, solar and atmospheric neutrinos, as well as neutrinos from a
super-beam and/or a beta-beam coming from CERN, is presented and compared with
competitor projects in Japan and in the USA. The performances of the European
project are discussed, including the possibility to measure the mixing angle
$\theta_{13}$ and the CP-violating phase $\delta$.


title:
First observation of quantum interference in the process phi -> KS KL
  ->pi+pi-pi+pi-: a test of quantum mechanics and CPT symmetry

abstract:
  We present the first observation of quantum interference in the process phi
-> KS KL ->pi+pi-pi+pi-.
  This analysis is based on data collected with the KLOE detector at the e^+e^-
collider DAFNE in 2001--2002 for an integrated luminosity of about 380pb^-1.
  Fits to the distribution of Delta t, the difference between the two kaon
decay times, allow tests of the validity of quantum mechanics and CPT symmetry.
  No deviations from the expectations of quantum mechanics and CPT symmetry
have been observed. New or improved limits on various decoherence and CPT
violation parameters have been obtained


title:
Search for Neutral, Long-lived Particles Decaying into Two Muons in
  p-pbar Collisions at sqrt(s) = 1.96 TeV

abstract:
  We present a search for a neutral particle, pair-produced in p-pbar
collisions at sqrt(s)=1.96 TeV, which decays into two muons and lives long
enough to travel at least 5 cm before decaying. The analysis uses ~380 pb^-1 of
data recorded with the D0 detector. The background is estimated to be about one
event. No candidates are observed, and limits are set on the pair production
cross section times branching fraction into dimuons + X for such particles. For
a mass of 10 GeV and lifetime of 4x10^-11 s, we exclude values greater than
0.14 pb (95% C.L.). These results are used to limit the interpretation of
NuTeV's excess of di-muon events.


title:
Improved Measurements of Color-Suppressed Decays B0bar -> D0 pi0, D0
  eta, D0 omega, D*0 pi0, D*0 eta and D*0 omega

abstract:
  We present improved measurements of the branching fractions of the
color-suppressed decays $\bar{B}^0 \to D^{(*)0} h^{0}$ where $h^{0}$ represents
a light neutral meson $\pi^{0}$, $\eta$ or $\omega$. The measurements are based
on a data sample of 140 $fb^{-1}$, collected at the $\Upsilon(4S)$ resonance
with the Belle detector at the KEKB energy-asymmetric $e^+e^-$ collider,
corresponding to seven times the luminosity of the previous Belle measurements.
All the measured branching fractions fall in the range 1.4-2.4 $\times
10^{-4}$, which is significantly higher than theoretical predictions based on
naive factorization.


title: Determination of the strong coupling constant at LEP

abstract:
  Multi-hadronic events produced in e+e- collisions provide an excellent
laboratory to study QCD, the theory of strong interactions, and in particular
to determine the strong coupling parameter alpha_s and demonstrate its
predicted behavior as a function of the energy scale. Determinations of alpha_s
at LEP will be reviewed with emphasis on event shape variables and jet rates in
3-jet and 4-jet events.


title:
Measurement of the CKM Matrix Elements |Vcb| and |Vub| at the
  B-factories

abstract:
  Recent results on inclusive and exclusive semileptonic B decays from
B-factories are presented. The impact of these measurements on the
determination of the CKM matrix elements |Vub| and |Vcb| is discussed.


title:
Search for associated Higgs boson production WH->WWW*->l+-nu l'+-nu'+X
  in p-pbar collisions at sqrt(s)=1.96 TeV

abstract:
  We present a search for associated Higgs boson production in the process
$p\bar{p} \to WH\to WWW^*\to l^\pm\nu l'^\pm\nu'+X$ in final states containing
two like-sign isolated electrons or muons ($e^\pm e^\pm$, $e^\pm \mu^\pm$, or
$\mu^\pm \mu^\pm$). The search is based on D0 Run II data samples corresponding
to integrated luminosities of 360--380 pb$^{-1}$. No excess is observed over
the predicted standard model background. We set 95% C.L. upper limits on
$\sigma(p\bar{p}\to WH)\times Br(H\to WW^*)$ between 3.2 and 2.8 pb for Higgs
masses from 115 to 175 GeV.


title: The overview of the spin physics at RHIC-PHENIX experiment

abstract:
  In Spiring 2005, RHIC successfully completed its first long data collection
run with polarized proton beams. PHENIX accumulated ten fold larger statistics
with higher polarization than the previous spin physics run in 2003. This
contribution will introduce the RHIC-PHENIX experiment and present our recent
results.


title: Light Quark Resonances in pbar p Annihilations at 5.2 GeV/c

abstract:
  Data from the Fermilab E835 experiment have been used to study the reaction
pbar p -> eta eta pi0 at 5.2 GeV/c. A sample of 22 million six photons events
has been analyzed to construct the Dalitz plot containing ~80k eta eta pi0
events. A partial wave analysis of the data has been done. Six f_J-states
decaying into eta eta and five a_J-states decaying into eta pi0 are identified
in the mass region ~1.3 and 2.4 GeV, and their masses, widths and spins are
determined by maximum likelihood analysis of the data. Two f_0 states are
identified with the popular candidates for the lightest scalar glueball,
f_0(1500) and f_0(1710).


title:
Measurement of the ttbar Production Cross Section in ppbar collisions at
  sqrt{s} = 1.96 TeV using Lepton+Jets Events with Jet Probability b-tagging

abstract:
  We present a measurement of the ttbar production cross section using events
with one charged lepton and jets from ppbar collisions at a center-of-mass
energy of 1.96 TeV. A b-tagging algorithm based on the probability of displaced
tracks coming from the event interaction vertex is applied to identify b quarks
from top decay. Using 318 pb^{-1} of data collected with the CDF II detector,
we measure the ttbar production cross section in events with at least one
restrictive (tight) b-tagged jet and obtain 8.9 +1.0-1.0 (stat.) +1.1-1.0
(syst.) pb. The cross section value assumes a top quark mass of m_{t}=178 GeV
in the acceptance corrections. The dependence of the cross section on m_t is
presented in the paper. This result is consistent with other CDF measurements
of the ttbar cross section using different samples and analysis techniques, and
has similar systematic uncertainties. We have also performed consistency checks
by using the b-tagging probability function to vary the signal to background
ratio and also using events that have at least two b-tagged jets.


title: Experimental results on heavy quark fragmentation

abstract:
  Experimental results on c- and b-quark fragmentation are reviewed. The
discussion is concentrated on measurements of heavy-quark fragmentation
functions and fragmentation fractions. Measurements of various heavy-quark
fragmentation ratios are also discussed. The experimental results are compared
with theoretical expectations and model predictions.


title: Measurement of B Decays to phi K gamma

abstract:
  We measure the branching fraction of the radiative B- decay B(B- -> phi K-
gamma) = (3.46 +/- 0.57^{+0.39}_{-0.37}) 10^-6, and set an upper limit on the
radiative B0 decay B(B0 -> phi K0 gamma) < 2.71 10^-6 at 90% confidence level.
We also measure the direct CP asymmetry of the B- -> phi K- gamma mode A_CP =
(-26.4 +/- 14.3 +/- 4.8)%. The uncertainties are statistical and systematic,
respectively. These measurements are based on 207 1/fb of data collected at the
Y4S resonance with the BABAR detector.


title: H1 Diffractive Structure Functions Measurement from new data

abstract:
  New measurements of the reduced cross section $\sigma_r^{D(3)}$ for the
diffractive process $ep \to eXY$ in the kinematic domain $12 \leq Q^2 \leq 90$
GeV$^2$, $0.01 \leq \beta \leq 0.65$ and $\xpom<0.1$ are presented. Data events
recorded by the H1 detector during the years 1999--2000 and 2004 have been
used, corresponding to a total integrated luminosity of 68 pb$^{-1}$. The
measurements are derived in the same range as previous H1 data, namely $M_Y <
1.6$ GeV and $|t| < 1.0$ GeV$^2$. Two different analysis methods, rapidity gap
and $M_X$, are used and similar results are obtained in the kinematic domain of
overlap. Finally, together with previous data, the diffractive structure
function measurements are analysed with a model based on the dipole formulation
of diffractive scattering. It is found to give a very good description of the
data over the whole kinematic range.


title:
Measurements of the Decays $B^0 \to \bar{D}^0\proton\antiproton$, $B^0
  \to \bar{D}^{*0}\proton\antiproton$, $B^0 \to D^{-}\proton\antiproton\pi^+$,
  and $B^0 \to D^{*-}\proton\antiproton\pi^+$

abstract:
  We present measurements of branching fractions of $B^0$ decays to multi-body
final states containing protons, based on 232 million $\Upsilon(4S)\to
B\bar{B}$ decays collected with the BaBar detector at the SLAC PEP-II
asymmetric-energy $B$ factory. We measure the branching fractions ${\cal B}(B^0
\to \bar{D}^0\proton\antiproton)=(1.13\pm0.06\pm0.08)\times 10^{-4}$, ${\cal
B}(B^0 \to \bar{D}^{*0}\proton\antiproton)=(1.01\pm0.10\pm0.09)\times 10^{-4}$,
${\cal B}(B^0 \to D^{-}\proton\antiproton\pi^+)=(3.38\pm0.14\pm0.29)\times
10^{-4}$, and ${\cal B}(B^0 \to
D^{*-}\proton\antiproton\pi^+)=(4.81\pm0.22\pm0.44)\times 10^{-4}$ where the
first error is statistical and the second systematic. We present a search for
the charmed pentaquark state, $\Theta_c(3100)$ observed by H1 and put limits on
the branching fraction ${\cal B} (B^0 \to \Theta_c \antiproton\pi^+)\times{\cal
B}(\Theta_c \to D^{*-}\proton)<14\times10^{-6}$ and ${\cal B}(B^0 \to \Theta_c
\antiproton\pi^+)\times{\cal B}(\Theta_c\to D^-\proton)<9\times10^{-6}$. Upon
investigation of the decay structure of the above four $B^{0}$ decay modes, we
see an enhancement at low $p\bar{p}$ mass and deviations from phase-space in
the $\bar{D}\bar{p}$ and $\bar{D}p$ invariant mass spectra.


title: Search for the Baryon and Lepton Number Violating Decays tau -> Lambda h

abstract:
  We have searched for the violation of baryon number B and lepton number L in
the (B-L)-conserving modes tau- -> anti-Lambda0 pi- and tau- -> anti-Lambda0 K-
as well as the (B-L)-violating modes tau- -> Lambda0 pi- and tau- -> Lambda0 K-
using 237 inv. fb of data collected with the BABAR detector at the PEP-II
asymmetric-energy e+e- storage ring. We do not observe any signal and determine
preliminary upper limits on the branching fractions B(tau- -> anti-Lambda0 pi-)
< 5.9 x 10^-8, B(tau- -> Lambda0 pi-) < 5.8 x 10^-8, B(tau- -> anti-Lambda0 K-)
< 7.2 x 10^-8, and B(tau- -> Lambda0 K-) < 15 x 10^-8 at 90% confidence level.


title: Rare Decays and Search for New Physics with BaBar

abstract:
  Rare B decays permit stringent tests of the Standard Model and allow searches
for new physics. Several rare radiative-decay studies of the B meson from the
BaBar collaboration are described. So far no sign for new physics was
discovered.


title: A Study of Xi_c(2980)^+ and Xi_c(3077)^+

abstract:
  We present a study of two states decaying to Lambda_c^+K^-pi^+ using the
BaBar detector at the SLAC PEP-II asymmetric-energy e^+e^- storage rings. We
use an integrated luminosity of 288.5 fb^{-1} collected at the center-of-mass
energy sqrt{s} = 10.58 GeV, near the peak of the Upsilon(4S) resonance, plus
27.2 fb^{-1} collected approximately 40 MeV below this energy. We search for
the particles Xi_{c}(2980)^+ and Xi_{c}(3077)^+, recently discovered by the
Belle Collaboration, in their decays to Lambda_c^+K^-pi^+, where
Lambda_c^+rightarrow pK^-pi^+. We find a signal with 7.0 sigma significance for
the Xi_c(2980)^+ state with a mass difference with respect to the Lambda_c^+ of
(680.6pm1.9pm1.0) MeV/c^2 (first error is statistical and second error is
systematic). The measured width for this state is (23.6pm2.8pm1.3) MeV, and the
yield is 284pm45pm46 events. We find a signal with 8.6 sigma significance for
the Xi_c(3077)^+ state with a mass difference with respect to the Lambda_c^+ of
(790.0pm0.7pm0.2) MeV/c^2, a width of (6.2pm1.6pm0.5) MeV, and a yield of
204pm35pm12 events. The Xi_{c}(2980)^+ is found to decay resonantly through the
intermediate state Sigma_c(2455)^{++}K^- with 4.9 sigma significance and
non-resonantly to Lambda_c^+K^-pi^+ with 4.1 sigma significance. With 5.8 sigma
significance, the Xi_c(3077)^+ is found to decay resonantly through
Sigma_c(2455)^{++}K^-, and with 4.6 sigma significance, it is found to decay
through Sigma_c(2520)^{++}K^-. The significance of the signal for the
non-resonant decay Xi_c(3077)^+rightarrow Lambda_c^+K^-pi^+ is 1.4 sigma. These
results are preliminary.


title:
Measurement of the Mass and Width and Study of the Spin of the Xi(1690)0
  Resonance from Lambdac+ --> Lambda anti-K0 K+ Decay at Babar

abstract:
  The Xi(1690)0 resonance is observed in the Lambda anti-K0 channel in the
decay Lambdac+ --> Lambda anti-K0 K+, from a data sample corresponding to a
total integrated luminosity of ~ 200 fb-1 recorded by the Babar detector at the
PEPII asymmetric-energy e+ e- collider operating at ~ 10.58 GeV and ~ 10.54 GeV
center-of-mass energies. A fit to the Dalitz plot intensity distribution
corresponding to the coherent superposition of amplitudes describing Lambda
a0(980)+ and Xi(1690)0 K+ production yields mass and width values of 1684.7 +/-
1.3 (stat.) +2.2 -1.6 (syst.) MeV/c2, and $8.1 +3.9 -3.5 (stat.) +1.0 -0.9
(syst.) MeV, respectively, for the Xi(1690)0, while the spin is found to be
consistent with value of 1/2 on the basis of studies of the (Lambda KS) angular
distribution.


title: Search for the reactions e+e- -> mu+ tau- and e+e- -> e+ tau-

abstract:
  We report on a search for the lepton-flavor-violating processes $e^+e^- \to
\mu^+\tau^-$ and $e^+e^- \to e^+\tau^-$. The data sample corresponds to an
integrated luminosity of 211 fb$^{-1}$ recorded by the BaBar experiment at the
SLAC PEP-II asymmetric-energy B Factory at a center-of-mass energy of $\sqrt{s}
= 10.58\ensuremath{\mathrm{Ge\kern -0.1em V}}$. We find no evidence for a
signal and set the 90% confidence level upper limits on the cross sections to
be $\sigma_{\mu\tau} <3.8$ \ensuremath{fb} and $\sigma_{e\tau}
<9.2$\ensuremath{fb}. The ratio of the cross sections with respect to the
dimuon cross section are measured to be $\sigma_{\mu\tau}/\sigma_{\mu\mu} <
3.4\times10^{-6}$ and $\sigma_{e\tau}/\sigma_{\mu\mu} < 8.2\times10^{-6}$.


title: Study of the Lepton Flavor Violating Decay $\tau^{-} \to \mu^{-} \eta$

abstract:
  We present the preliminary results from the search of the non-conservation of
lepton flavor number in the decay of a $\tau$ to a lighter mass lepton and a
pseudo-scalar meson, performed using $e^+e^- \to \tau^+\tau^-$ events collected
at a center-of-mass energy near 10.58 GeV with the BABAR detector at the SLAC
PEP-II $e^+e^-$ storage ring. No evidence of such a signal has been found in
the data sample corresponding to a luminosity of 314.5 fb$^{-1}$, and we set an
upper limit of $1.6\times 10^{-7}$ at 90% confidence level on the decay of
$\tau^- \to \mu^-\eta$.


title:
A Measurement of the Psi' to J/psi Production Ratio in 920 GeV
  Proton-Nucleus Interactions

abstract:
  Ratios of the Psi' over the J/psi production cross sections in the dilepton
channel for C, Ti and W targets have been measured in 920 GeV proton-nucleus
interactions with the HERA-B detector at the HERA storage ring. The Psi' and
J/psi states were reconstructed in both the mu+mu- and the e+e- decay modes.
The measurements covered the kinematic range -0.35 < x_F < 0.1 with transverse
momentum p_T < 4.5 GeV/c. The Psi' to J/psi production ratio is almost constant
in the covered x_F range and shows a slow increase with p_T. The angular
dependence of the ratio has been used to measure the difference of the Psi' and
J/psi polarization. All results for the muon and electron decay channels are in
good agreement: their ratio, averaged over all events, is
R_psi'(mu)/R_psi'(e)=1.00+-0.08+-0.04. This result constitutes a new, direct
experimental constraint on the double ratio of branching fractions,
(B'(mu)*B(e))/(B(mu)*B'(e)), of Psi' and J/psi in the two channels.


title: Search for Excited Neutrinos at HERA

abstract:
  A search for excited neutrinos produced in electron--proton collisions is
performed using a data sample corresponding to an integrated luminosity of 114
pb$^{-1}$ recently collected by the H1 detector at HERA. In absence of a
signal, the measurement is interpreted within a minimal model parameterised in
terms of couplings and compositness scale. New parameter regions, beyond other
colliders sensitivities, are explored by the present preliminary analysis.


title: Search for the rare decay B to pi l+ l-

abstract:
  We present results of a search for the rare flavor-changing neutral-current
decay B --> pi l+ l-, based on a data sample corresponding to 209 fb-1 of
integrated luminosity collected with the BABAR detector at the PEP-II B
Factory. We reconstruct the four exclusive B decay modes B+ --> pi+ l+ l- and
B0 --> pi0 l+ l-, where l is either an e or mu. We find no evidence for a
signal, and we obtain the upper limit at 90% confidence level on the
lepton-flavor--averaged branching fraction to be BF(B+ --> pi+ l+ l-) = 2 x
tau_B+/tau_B0 x BF(B0 --> pi0 l+ l-) < 7.9 x 10-8. We also obtain an upper
limit at 90% confidence level on the lepton-flavor--violating decay B --> pi e
mu of BF(B --> pi e mu) < 9.8 x 10-8.


title: About Detecting CP-Violating Processes in $J/\psi\to \KzKzb $ Decay

abstract:
  Questions about detecting CP-violating decay process of $J/\psi\to
K^0\bar{K}^0\to K_SK_S$ are discussed. Possible background and material
regeneration effect are analyzed. The discussion can be directly extended to
other vector quarkonium decays, like $\Upsilon$, $\psi (2S)$ and $\phi\to K_S
K_S$.


title: Search for B+ --> X(3872) K+, X(3872) --> J/psi gamma

abstract:
  In a study of B+ --> J/psi gamma K+ decays, we find evidence for the
radiative decay X(3872) --> J/psi gamma with a statistical significance of 3.4
sigma. We measure the product of branching fractions BF(B+ --> X(3872)
K+).BF(X(3872) --> J/psi gamma) = (3.3 +/- 1.0 +/- 0.3) x 10^-6, where the
uncertainties are statistical and systematic, respectively. We also measure the
branching fraction BF(B+ --> chi_c1 K+) = (4.9 +/- 0.2 +/- 0.4) x 10^-4. These
results are obtained from (287+/-3) million BBar decays collected at the Y(4S)
resonance with the BaBar detector at the PEP-II B Factory at SLAC.


title: Search for Flavor-Changing Neutral-Current Charm Decays

abstract:
  We search for rare FCNC charm decays of the form $X_c^+\to h^+\llp$, where
$X_c^+$ is a charm hadron, $h$ is a pion, kaon or proton, and $\ell^{(}{'}^{)}$
is an electron or a muon. In the pion and kaon modes, we study both $D^+$ and
$D_s^+$ decays, while in the proton modes we study $\Lambda_c^+$ decays. Based
on a data sample of 288${fb}^{-1}$ of $e^+e^-$ collisions collected by BABAR,
we set preliminary 90% confidence level limits between 4 to 40$\times10^{-6}$
for the branching fractions of the different decay modes. For most decay modes,
our analysis provides a significant improvement over previous results.


title:
Study of Particle Production in Quark vs. Gluon Fragmentation at sqrt s
  ~ 10GeV

abstract:
  Using data collected with the CLEO III detector at the Cornell Electron
Storage Ring, we have compared proton, lambda (charged conjugate modes are
implicit) and meson (phi and f2(1270)) production observed in gluon
fragmentation vs. quark fragmentation. Two studies have been conducted: in the
first, we corroborrate previous per-event particle yields in Upsilon(1S)->ggg
vs. e+e- -> qqbar. In the second, we compare particle production in the
photon-tagged process U(1S)->gggamma with that in e+e- -> qqbargamma events.
For each particle, we determine the `enhancement' ratio, defined as the ratio
of particle yields per gluon fragmentation event compared to quark
fragmentation event. Thus defined, an enhancement of 1.0 implies equal
per-event production in both gluon and quark fragmentation. In the
photon-tagged analysis, we find an enhancement of order unity for protons and
approximately 1.5 for lambda's. This measured proton enhancement rate is
supported by a study of baryon production in chib(J=2)->proton+X relative to
chib(J=1)->proton+X. The production of mesons having masses of order 1 GeV (phi
and f2(1270)) are found to be also approximately the same in gggamma vs.
qqbargamma fragmentation. Overall, per-event baryon production in two-gluon
fragmentation is considerably smaller than that observed in three-gluon decays
of the Upsilon(1S). Our results for baryon production are inconsistent with the
predictions of the JETSET (7.4) fragmentation model.


title: Search for inclusive charmless B->K+X and B->K0X decays

abstract:
  We present preliminary results from a search for inclusive charmless B->KX
decays. These decays occur dominantly via one-loop b->s penguin transitions,
and can provide useful information about these processes. Using a sample of
288.5/fb collected with the BABAR detector at the PEP-II asymmetric-energy e+e-
B Factory at SLAC, we search for high-energy kaons recoiling against fully
reconstructed B decays. We measure the partial branching fractions for kaons
with momentum p*(K)>2.34GeV in the B rest frame, and obtain (in units of
10^-6): B(B->K+X, p*>2.34GeV) = 196^{+37}_{-34}(stat.)^{+31}_{-30}(syst.) and
B(B->K0X, p*>2.34GeV) = 154^{+55}_{-48}(stat.)^{+55}_{-41}(syst.) (<266 at 90%
C.L.).


title: Measurement of Upper Limits for Upsilon to gamma + Resonance Decays

abstract:
  Motivated by concerns regarding possible two-body contributions to the
recently-measured inclusive $\Upsilon$(nS)$\to\gamma+X$ direct photon spectrum,
we report on a preliminary new study of exclusive radiative decays of the
$\Upsilon$ resonances into two-body final states ${\cal R}\gamma$, with ${\cal
R}$ some resonant hadronic state decaying into four or more charged particles.
Such two-body processes are not explicitly addressed in the extant theoretical
frameworks used to calculate the inclusive direct photon spectrum. Using data
collected from the CLEO III detector at the Cornell Electron Storage Ring, we
present upper limits for such $\Upsilon({\rm 1S})$, $\Upsilon({\rm 2S})$, and
$\Upsilon({\rm 3S})$ two-body decays as a function of the recoil mass $M_{\cal
R}$. Additionally, we place upper limits on the cross-section for ${\cal R}$
production via radiative return for center-of-mass energies just below the
$\Upsilon({\rm 1S})$, $\Upsilon({\rm 2S})$, and $\Upsilon({\rm 3S})$ energies.
The results presented in this document are preliminary.


title:
Measurement of the Branching Fractions of the Decays $\bar{B}^{0} \to
  \Lambda_{c}^{+} \bar{p}$ and $B^{-} \to \Lambda_{c}^{+} \bar{p} \pi^{-}$

abstract:
  We present studies of two-body and three-body charmed baryonic B decays in a
sample of 232 million $B\bar{B}$ pairs collected with the BABAR detector at the
PEP-II $e^+e^-$ storage ring. The branching fractions of the decays
$\bar{B}^{0} \to \Lambda_{c}^{+} \bar{p}$ and $B^{-} \to \Lambda_{c}^{+}
\bar{p} \pi^{-}$ are measured to be $(2.15 \pm 0.36 \pm 0.13 \pm 0.56) \times
10^{-5}$ and $(3.53 \pm 0.18 \pm 0.31 \pm 0.92)\times10^{-4}$, respectively.
The uncertainties quoted are statistical, systematic, and from the
$\Lambda_{c}^{+} \to p K^- \pi^+$ branching fraction. We observe a
baryon-antibaryon threshold enhancement in the $\Lambda_{c}^{+} \bar{p}$
invariant mass spectrum of the three-body mode and measure the ratio of the
branching fractions to be ${\cal B}(B^{-} \to \Lambda_{c}^{+} \bar{p}
\pi^{-})/{\cal B}(\bar{B}^{0} \to \Lambda_{c}^{+} \bar{p}) = 16.4 \pm 2.9 \pm
1.4$. These results are preliminary.


title:
Improved Measurement of the Branching Fraction and Engery Spectrum of
  eta' from Upsilon(1S) Decays

abstract:
  We present an improved measurement of the eta' meson energy spectrum in
Upsilon(1S) decays, using 1.2 fb^{-1}} of data taken at the Upsilon(1S)
center-of-mass energy with the CLEO III detector. We compare our results with
models of eta' gluonic form factor that have been suggested to explain the
unexpectedly large B to eta' X_s rate. Models based on perturbative QCD fail to
fit the data for large eta' energies, showing that Standard Model strong
interaction dynamics is not likely to provide an explanation for the large rate
of high energy eta' observed in B decays.

Measurements of branching fractions, polarizations, and direct
  CP-violation asymmetries in B --> rho K* and B --> f0(980) K* decays

abstract:
  We report searches for B-meson decays to the charmless final states rho K*
and f0(980) K* with a sample of 232 million BBbar pairs collected with the
BABAR detector at the PEP-II asymmetric-energy e+e- collider at SLAC. We
measure the following branching fractions in units of 10^{-6}: B (B+ --> rho0
K*+) = 3.6 +/- 1.7 +/- 0.8 (< 6.1), B (B+ --> rho+ K*0) = 9.6 +/- 1.7 +/- 1.5,
B (B0 --> rho- K*+) = 5.4 +/- 3.6 +/- 1.6 (< 12.0), B (B0 --> rho0 K*0) = 5.6
+/- 0.9 +/- 1.3, B (B+ --> f0(980) K*+) = 5.2 +/- 1.2 +/- 0.5, and B (B0 -->
f0(980) K*0) = 2.6 +/- 0.6 +/- 0.9 (< 4.3). The first error quoted is
statistical, the second systematic, and the upper limits, in parentheses, are
given at the 90% confidence level. For the statistically significant modes we
also measure the fraction of longitudinal polarization and the charge
asymmetry: f_L (B+ --> rho+ K*0) = 0.52 +/- 0.10 +/- 0.04, f_L (B0 --> rho0
K*0) = 0.57 +/- 0.09 +/- 0.08, A_CP (B+ --> rho+ K*0) = -0.01 +/- 0.16 +/-
0.02, A_CP (B0 --> rho0 K*0) = 0.09 +/- 0.19 +/- 0.02, A_CP (B+ --> f_0(980)
K*+) = -0.34 +/- 0.21 +/- 0.03, and A_CP (B0 --> f_0(980) K*0) = -0.17 +/- 0.28
+/- 0.02.

A Search for the $B^0 \to e^+e^-\gamma$ and $B^0 \to \mu^+\mu^-\gamma$
  Decays

abstract:
  With the BaBar detector at the PEP-II asymmetric $B$ Factory at SLAC, we
present the first search for the decays $B^0\to\ell^+\ell^-\gamma$ ($l=e,
\mu$). Using a data set of 292 $fb^{-1}$ collected at the $\Upsilon(4S)$
resonance, we find no significant signal and set the following branching
fraction upper limits at 90% confidence level: $\mathcal{B}(B^0\to
e^+e^-\gamma)<0.7\times 10^{-7}$ and $\mathcal{B}(B^0\to
\mu^+\mu^-\gamma)<3.4\times 10^{-7}$.

A Measurement of Atmospheric Neutrino Flux Consistent with Tau Neutrino
  Appearance

abstract:
  A search for the appearance of tau neutrinos from \mutau oscillations in the
atmospheric neutrinos has been performed using 1489.2 days of atmospheric
neutrino data from the Super-Kamiokande-I experiment. A best fit tau neutrino
appearance signal of 138 $\pm$ 48 (stat.) $^{+15}_{-32}$ (sys.) events is
obtained with an expectation of 78 $\pm$ 26 (sys.). The hypothesis of no tau
neutrino appearance is disfavored by 2.4 sigma.


title:
Measurement of the B0->pilnu Form Factor Shape and Branching Fraction,
  and Determination of |Vub| with a Loose Neutrino Reconstruction Technique

abstract:
  We report the results of a study of the exclusive charmless semileptonic
B0->pilnu decay undertaken with approximately 227 million BBbar pairs collected
at the Upsilon(4S) resonance with the BABAR detector. The analysis uses events
in which the signal B mesons are reconstructed with a novel loose neutrino
reconstruction technique. We obtain partial branching fractions in 12 bins of
q2, the l+nu invariant mass squared, from which we extract the f+(q2) form
factor shape and the total branching fraction: BF(B0->pilnu) = (1.44 +-
0.08(stat) +- 0.10(syst))x 10-4. Based on a recent theoretical calculation of
the form factor, we find the magnitude of the CKM matrix element |Vub| to be
(4.1 +- 0.2(stat) +- 0.2(syst) +0.6-0.4(FF))x 10-3, where the last uncertainty
is due to the normalization of the form factor.


title: Delta G from Compass

abstract:
  Measurements of the gluon polarization $\frac{\Delta G}{G}$ via the open
charm channel and based on the helicity asymmetry of large transverse-momentum
hadrons in the final state are presented. The data have been collected in the
years 2002-2004 by the COMPASS experiment at CERN using a 160 GeV/c polarized
muon beam scattered off a polarized $^6$LiD target. The new result for
$\frac{\Delta G}{G}$ from the charm channel is $-0.57 \pm 0.41 (stat.)$ at $x_G
\simeq 0.15$ and scale $\mu^2 \simeq 13 $ (GeV/c)$^2$. The gluon polarization
from high-$p_T$ hadron pairs is $\frac{\Delta G}{G} = 0.016\pm 0.058 (stat.)\pm
0.055 (syst.)$ at $x_G \simeq 0.085^{+0.07}_{-0.035}$ ($Q^2 < 1$ (GeV/c)$^2$
and $\mu^2 \simeq 3$ (GeV/c)$^2$)


title: Observation of the decays B- to Ds(*)+ K- pi-

abstract:
  We report first observations of the decays B- to Ds(*)+ K- pi-, using 292
fb^-1 of data collected at Upsilon(4S) resonance energy by the BaBar detector
at the PEP II e+ e- collider. The branching fractions are measured to be B(B-
to Ds+ K- pi-) = (1.88 +- 0.13 +- 0.41) x 10^-4 and B(B- to Ds*+ K- pi-) =
(1.84 +- 0.19 +- 0.40) X 10^-4.


title:
Searches for B0 decays to eta K0, eta eta, eta' eta', eta phi, and eta'
  phi

abstract:
  We search for B0 meson decays into two-body combinations of K0, eta, eta',
and phi mesons in 324 million B Bbar pairs collected with the BaBar detector at
the PEP-II asymmetric-energy e+e- collider at SLAC. We measure the following
branching fractions (upper limits at 90% confidence level) in units of 10^{-6}:
Br(B0->eta K0) =1.8+0.7-0.6 +-0.1(2.9), Br(B0->eta eta)=1.1+0.5-0.4 +-0.1(1.8),
Br(B0->eta phi)=0.1+-0.2 +-0.1(0.6), Br(B0->eta' phi)=0.2+0.4-0.3 +-0.1(1.0),
Br(B0->eta' eta')=1.0+0.8-0.6 +-0.1(2.4), where the first error is statistical
and the second systematic.


title: Search for the rare decay B+ -> a0+pi0

abstract:
  A search for the decay B+ -> a0+pi0 with the a0+ decaying to an eta and a pi+
was carried out at the Stanford Linear Accelerator Center using the BABAR
detector coupled with the PEP-II collider. The analysis used a data sample
comprised of approximately 252 million BBbar pairs collected at the Upsilon(4S)
resonance. No signal was observed and a 90% confidence level upper limit on the
branching fraction was set at 1.32 x 10^{-6}.


title: Search for b--> u transitions in B- -> [K+pi-pi0]_D K-

abstract:
  We search for decays of a B meson into a neutral D meson and a kaon, with the
D meson decaying into K+pi-pi0. This final state can be reached through the b
--> c transition B- -> D0K- followed by the doubly Cabibbo-suppressed D0 -->
K+pi-pi0, or the b --> u transition B- --> D0bar K- followed by the
Cabibbo-favored D0bar --> K+ pi-pi0. The interference of these two amplitudes
is sensitive to the angle gamma of the unitarity triangle. We present
preliminary results based on 226 10^{6} e+e- --> Y(4s) --> BBbar events
collected with the BABAR detector at SLAC. We find no significant evidence for
these decays and we set a limit R_ADS =(BR(B- -->[K+pi-pi0]_D K-)+ BR(B- -->
[K-pi+pi0]_D K+))/(BR(B- -->[K-pi+pi0]_D K-)+ BR(B- --> [K+pi-pi0]_D K+))<0.039
at 95% confidence level, which we translate with a Bayesian approach into r_B =
|A(B- --> D0bar K-)|/|A(B- --> D0bar K-)| < 0.185 at 95% confidence level.


title:
Measurement of the B+ --> eta l+ nu and B+ --> eta' l+ nu Branching
  Fractions using Upsilon(4S)-->BBbar Events Tagged by a Fully Reconstructed B
  Meson

abstract:
  We report preliminary measurements of the exclusive charmless semileptonic
branching fractions of the B+ --> eta l+ nu and B+ --> eta' l+ nu decays. These
measurements are based on 316 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 recoiling B
meson is identified by the detection of a charged lepton and an eta or eta'. We
measure the branching fraction BR(B+ --> eta l+ nu) = (0.84 +/- 0.27 +/- 0.21)
x 10-4, where the first error is statistical and the second one systematic. We
also set an upper limit on the branching fraction of BR(B+ --> eta l+ nu) < 1.4
x 10-4 and BR(B+ --> eta' l+ nu) < 1.3 x 10^-4 at the 90% confidence level.


title:
Measurement of the Relative Branching Fractions for B- ->
  D/D*/D**(D(*)pi) l- anti-nu with a Large Sample of Tagged B Mesons

abstract:
  We present a study of B semileptonic decays into charm final states based on
211.7 fb^{-1} of data collected at the \Upsilon(4S) resonance with the babar
detector at the pep2 e^+e^- storage ring. Using a novel technique based on the
simultaneous fit of a set of variables reconstructed on the recoil of a B
tagged in an hadronic decay mode, we measure the relative branching fractions
\Gamma(B^- \to D^0\ell^- \bar{\nu}_{\ell}) / \Gamma(B^- \to D X \ell^-
\bar{\nu}_{\ell}) = 0.210 \pm 0.017 (stat.) \pm 0.021 (syst.), \Gamma(B^- \to
D^{*0}\ell^- \bar{\nu}_{\ell}) / \Gamma(B^- \to D X \ell^- \bar{\nu}_{\ell}) =
0.611 \pm 0.022 (stat.) \pm 0.027 (syst.) and \Gamma(B^- \to
D^{**0}(D^{(*)}\pi)\ell^- \bar{\nu}_{\ell}) / \Gamma(B^- \to D X \ell^-
\bar{\nu}_{\ell}) = 0.173 \pm 0.017 (stat.) \pm 0.021 (syst.) .


title: Comparison of D to K0L pi and D to K0S pi Decay Rates

abstract:
  We present preliminary measurements of D to K^0_L pi and D to K^0_S pi
branching fractions using 281 pb^{-1} of psi(3770) data at the CLEO-c
experiment. We find that BF(D^0 to KS pi^0) is larger than BF(D^0 to KL pi^0),
with an asymmetry of R(D^0) = 0.122 +- 0.024 +- 0.030. For BF(D^+ to KS pi^+)
and BF(D^+ to KL pi^+), we observe no measureable difference; the asymmetry is
R(D^+) = 0.030 +- 0.023 +- 0.025. Under reasonable theoretical assumptions,
these measurements imply a value for the D^0 to K^+- pi^-+ strong phase that is
consistent with zero. The results presented in this document are preliminary.


title: Dalitz Analysis of D^+ to pi^+ pi^- pi^+

abstract:
  Using 281/pb of data recorded by the CLEO-c detector observing e+e-
collisions at the psi(3770), corresponding to 1.8 million D Dbar pairs, the
substructure of the decay D+ to pi+ pi- pi+ is investigated using the Dalitz
plot technique. The results presented in this document are preliminary.


title: Status of Charm Flavor Physics

abstract:
  The role of charm in testing the Standard Model description of quark mixing
and CP violation through measurements of lifetimes, decay constants and
semileptonic form factors is reviewed. Together with Lattice QCD, charm has the
potential this decade to maximize the sensitivity of the entire flavor physics
program to new physics. and pave the way for understanding physics beyond the
Standard Model at the LHC in the coming decade. The status of indirect searches
for physics beyond the Standard Model through charm mixing, CP-violation and
rare decays is also reported.


title:
Measurement of the Branching Fraction and Photon Energy Moments of
  B->X_s gamma and A_{cp}(B->X_(s+d) gamma)

abstract:
  The photon spectrum in B -> X_s gamma decay, where X_s is any strange
hadronic state, is studied using a data sample of 88.5 million e+e- ->
Upsilon(4S) -> BBbar decays collected by the BaBar experiment at SLAC. The
partial branching fraction, Delta B(B -> X_s gamma)=(3.67 +- 0.29(stat.) +-
0.34(sys.) +- 0.29(model)) times 10^-4, the first moment <E_gamma>=2.288 +-
0.025 +- 0.017 +- 0.015 GeV and the second moment <E_gamma^2> - <E_gamma>^2
=0.0328 +- 0.0040 +- 0.0023 +- 0.0036 GeV^2 are measured for the photon energy
range 1.9 GeV < E_gamma < 2.7 GeV. They are also measured for narrower E_gamma
ranges. The moments are then fit to recent theoretical calculations to extract
the Heavy Quark Expansion parameters, m_b and mu_pi^2, and to extrapolate the
partial branching fraction to E_gamma>1.6 GeV. In addition, the direct CP
asymmetry A_CP(B -> X_(s+d) gamma) is measured to be -0.110 +- 0.115(stat.) +-
0.017(sys.).


title: chi_cJ Decays to h^+h^-h^0

abstract:
  Using a sample of 3x10^6 psi(2S) decays recorded by the CLEO detector, we
study three body decays of the chi_{c0}, chi_{c1}, and chi_{c2} produced in
radiative decays of the psi(2S). We consider the decay modes pi+ pi- eta, K+ K-
eta, p pbar eta, pi+ pi- etaprime, K+ K- pi0, p pbar pi0, pi+ K- K0S, and K+
pbar Lambda measuring branching fractions or placing upper limits. For chi_{c1}
to pi+ pi- eta, K+ K- pi0, and pi+ K- K0S our observed samples are large enough
to study the substructure in a Dalitz plot analysis. The results presented in
this document are preliminary.


title:
On CP violation and the measurement of the dimuon charge asymmetry at
  hadron colliders

abstract:
  B factories measure the CP violation parameter of B^0 Bbar^0 mixing and
decay. Hadron colliders measure the dimuon charge asymmetry of an admixture of
B hadrons. In this note we discuss a subtle point on how the CP violation
parameter of B^0_s Bbar^0_s mixing and decay can be extracted from these
measurements.


title: Measurement of Ds+ to mu+ nu and the Decay constant f_Ds

abstract:
  We examine e+e- to Ds- Ds*+ or Ds-* Ds+ collisions at 4170 MeV using the
CLEO-c detector in order to measure the decay constant f_Ds+. We use the Ds+ to
ell+ nu channel, where the ell+ designates either a mu+ or a tau+. Analyzing
both modes simultaneously, we determine B(D_s^+ to mu+ nu)= (0.657 +- 0.090 +-
0.028)%, B(D_s^+ to tau+ nu)= (7.1 +- 1.4 +- 0.3)%, and extract f_Ds+ = 282 +-
16 +- 7 MeV. Combining with our previous determination of B(D+ to mu+ nu), we
find that the ratio f_Ds+/f_D+ = 1.27 +- 0.12 +- 0.03. (All new results here
are preliminary.) We compare with current theoretical estimates.


title:
Branching Fraction for the Doubly-Cabibbo-Suppressed Decay D^+ to K^_
  pi^0

abstract:
  We present a measurement of the branching fraction for the
doubly-Cabibbo-suppressed decay D+ to K+ pi0, using 281 pb-1 of data
accumulated with the CLEO-c detector on the psi(3770) resonance. We find B(D+
to K+ pi0) = (2.25 +- 0.36 +- 0.15 +- 0.07) times 10^{-4}, where the first
uncertainty is statistical, the second is systematic, and the last error is due
to the uncertainty in the reference mode. The results presented in this
document are preliminary.


title:
Determination of the Form Factors for the Decay B0 --> D*-l+nu_l and of
  the CKM Matrix Element |Vcb|

abstract:
  We present a combined measurement of the Cabibbo-Kobayashi-Maskawa matrix
element $|V_{cb}|$ and of the parameters $\rho^2$, $R_1$, and $R_2$, which
fully characterize the form factors of the $B^0 \to D^{*-}\ell^{+}\nu_\ell$
decay in the framework of HQET, based on a sample of about 52,800 $B^0 \to
D^{*-}\ell^{+}\nu_\ell$ decays recorded by the BABAR detector. The kinematical
information of the fully reconstructed decay is used to extract the following
values for the parameters (where the first errors are statistical and the
second systematic): $\rho^2 = 1.156 \pm 0.094 \pm 0.028$, $R_1 = 1.329 \pm
0.131 \pm 0.044$, $R_2 = 0.859 \pm 0.077 \pm 0.022$, $\mathcal{F}(1)|V_{cb}| =
(35.03 \pm 0.39 \pm 1.15) \times 10^{-3}$. By combining these measurements with
the previous BABAR measurements of the form factors which employs a different
technique on a partial sample of the data, we improve the statistical accuracy
of the measurement, obtaining: $\rho^2 = 1.179 \pm 0.048 \pm 0.028, R_1 = 1.417
\pm 0.061 \pm 0.044, R_2 = 0.836 \pm 0.037 \pm 0.022, $ and $
\mathcal{F}(1)|V_{cb}| = (34.68 \pm 0.32 \pm 1.15) \times 10^{-3}.$ Using the
lattice calculations for the axial form factor $\mathcal{F}(1)$, we extract
$|V_{cb}| =(37.74 \pm 0.35 \pm 1.25 \pm ^{1.23}_{1.44}) \times 10^{-3}$, where
the third error is due to the uncertainty in $\mathcal{F}(1)$.


title:
Measurement of the q2 dependence of the Hadronic Form Factor in D0 -->
  K- e+ nu_e decays

abstract:
  We present a preliminary measurement of the q2 dependence of the D0 --> K- e+
nu_e decay rate. This rate is proportional to the hadronic form factor squared,
specified by a single parameter. This is either the mass in the simple pole
ansatz m_pole = (1.854 +- 0.016 +- 0.020) GeV/c2 or the scale in the modified
pole ansatz alpha_pole = 0.43 +- 0.03 +- 0.04. The first error refers to the
statistical, the second to the systematic uncertainty.


title: D0barD0 Quantum Correlations, Mixing, and Strong Phases

abstract:
  Due to the quantum correlation between the pair-produced D0 and D0bar from
the decay of the psi(3770), the time-integrated single and double tag decay
rates depend on charm mixing amplitudes, doubly-Cabibbo-suppressed amplitudes,
and the relative strong phase delta between D0 and D0bar decays to identical
final states. Using 281 pb^{-1} collected with the CLEO-c detector on the
psi(3770) resonance, we measure the absolute branching fractions of D0 decays
to hadronic flavored states, CP eigenstates, and semileptonic final states to
determine the relative strong phase, cos delta, of the K- pi+ final state and
to limit the mixing amplitude y. The results presented in this document are
preliminary.


title: Measurement of Absolute Hadronic Branching Fractions of D_s Mesons

abstract:
  We report preliminary measurements of absolute hadronic branching fractions
of Ds mesons determined using a double tag technique. These measurements are
from 195 pb^{-1} of e+e- collisions recorded at center of mass energies near
4.17 GeV with the CLEO-c detector at CESR. We obtain absolute branching
fractions for Ds+ decays to KS0 K+, K- K+ pi+, K- K+ pi+ pi-, pi+ pi+ pi-, pi+
eta, and pi+ etaprime. We discuss the problems inherent in measuring accurately
the branching fraction for Ds+ to phi pi+, which is often used as a reference
mode for measurement of other Ds+ branching fractions, and provide a
measurement of a branching fraction that may be useful for this purpose.


title: Measurement of B9Upsilon(5S) to Bs(*) Bs(*)bar Using phi Mesons

abstract:
  Knowledge of the Bs decay fraction of the Y(5S) resonance, fs, is important
for Bs meson studies at the Y(5S) energy. Using data collected by the CLEO III
detector at CESR consisting of 0.423 1/fb on the Y(5S) resonance, 6.34 1/fb on
the Y(4S) and 2.32 1/fb in the continuum below the Y(4S), we measure B(Y(5S)->
phi X)=(13.2+/- 0.7 ^{+2.2}_{-1.4})% and B(Y (4S)-> phi X)=(7.1 +/- 0.1 +/-
0.6)%, the ratio of the two rates is (1.9 +/- 0.1 ^{+0.3}_{-0.2}). This is the
first measurement of the phi meson yield from the Y(5S). Using these rates, and
a model dependent estimate of B(Bs -> phi X), we measure fs=(27.3 +/- 3.2
^{+14.6}_{-~6.1})%. We update our previous, independent measurement of this
branching fraction using the inclusive Ds yields to be (21.8 +/- 3.4
^{+8.5}_{-4.2})%, due to changes in the $D_s^+ -> phi \pi^+$ branching fraction
and a better estimate of the number of hadronic events. We also report the
total Y(5S) hadronic cross section above continuum to be sigma(e^+e^- ->
Y(5S))=(0.301 +/- 0.002 +/- 0.039) nb. This allows us to extract the fraction
of B mesons as (58.9+/-10.0+/-9.2)%, equal to 1-fs. Averaging the three methods
gives a model dependent result of fs=(26^{+7}_{-4})%.


title:
Measurement of Decay Amplitudes of \B \to (\ccbar) \Kstar with an
  angular analysis, for (\ccbar)=\jpsi, \psitwos and \chicone

abstract:
  We perform the first three-dimensional measurement of the amplitudes of
$B\to\psi{(2S)}K^*$ and $B\to\chi_{c1}K^*$ decays and update our previous
measurement for $B\to{J\mskip -3mu/\mskip -2mu\psi\mskip 2mu}K^*$. We use a
data sample collected with the {\slshape BABAR} detector at the PEP-II storage
ring, representing 232 million produced $B{\kern 0.18em\bar{\kern -0.18em B}}$
pairs. The longitudinal polarization of decays to the $1^{++} \chi_{c1}$ meson
together with a $K^*$ meson, is found to be larger than that for the decay to
the $1^{--} \Psi$ mesons. No direct CP-violating charge asymmetry is observed.


title: Observation of a New D_s Meson Decaying to D K at a Mass of 2.86 GeV/c^2

abstract:
  We observe a new D_s meson with mass (2856.6 +/- 1.5_{stat.} +/- 5.0_{syst.})
MeV/c^2 and width (48 +/- 7_{stat.} +/- 10_{syst.}) MeV decaying into D^0 K^+
and D^+K^0_S. In the same mass distributions we also observe a broad structure
with mass (2688 +/- 4_{stat.} +/- 3_{syst.}) MeV/c^2 and width (112 +/-
7_{stat.} +/- 36_{syst.}) MeV. To obtain this result we use 240 fb^-1 of data
recorded by the BaBar detector at the PEP-II asymmetric-energy e^+e^- storage
rings at the Stanford Linear Accelerator Center running at center-of-mass
energies near 10.6 GeV.

  A study of exclusive production of the $D \bar D$ system through
initial-state r adiation is performed in a search for charmonium states, where
$D=D^0$ or $D^+$. The $D^0$ mesons are reconstructed in the $D^0 \to K^-
\pi^+$, $D^0 \to K^- \pi^+ \pi^0$, and $D^0 \to K^- \pi^+ \pi^+ \pi^-$ decay
modes. The $D^+$ is reconstructed through the $D^+ \to K^- \pi^+ \pi^+$ decay
mode. The analysis makes use of an integrated luminosity of 288.5 fb$^{-1}$
collected by the BaBar experiment. The $D \bar D$ mass spectrum shows a clear
$\psi(3770)$ signal. Further structures appear in the 3.9 and 4.1 GeV/$c^2$
regions. No evidence is found for Y(4260) decays to $D \bar D$, implying an up
per limit $\frac{\BR(Y(4260)\to D \bar D)}{\BR(Y(4260)\to J/\psi \pi^+ \pi^-)}
< 7.6$ (95 % confidence level).


title: A precision measurement of the D_s1(2536) meson mass and decay width

abstract:
  The decay width and the mass of the D_s1(2536) have been measured via the
decay channel D_s1 -> D*+K_S using 232 fb^-1 of data collected with the BABAR
detector at the PEP-II asymmetric-energy e+e- storage ring. The result for the
decay width is (1.03 +- 0.05 +- 0.12) MeV/c^2, with the first error denoting
the statistical uncertainty and the second one the systematic uncertainty. For
the mass, a value of (2534.85 +- 0.02 +- 0.40) MeV/c^2 has been obtained. The
systematic error is dominated by the uncertainty on the D*+ mass. The mass
difference between the D_s1 and D*+ has been measured to be (524.85 +- 0.02 +-
0.04) MeV/c^2.


title: Measurement of the Hadronic Form Factors in Ds -> phi e nu Decays

abstract:
  Based on the measured four-dimensional rate for $D_{s}^+ to \phi e^+ \nu_e$
decays, we have determined the ratios of the three hadronic form factors,
r_V=V(0)/A_1(0)= 1.636 \pm 0.067 \pm 0.038 and r_2=A_2(0)/A_1(0)= 0.705 \pm
0.056 \pm 0.029, using a simple pole ansatz for the $q^2$ dependence, with
fixed values of the pole masses for both the vector and axial form factors. By
a separate fit to the same data, we have also extracted the pole mass for the
axial form factors, $m_A$: r_V=V(0)/A_1(0)= 1.633 \pm 0.081 \pm 0.068
,r_2=A_2(0)/A_1(0)= 0.711 \pm 0.111 \pm 0.096 and m_A=(2.53^{+0.54}_{-0.35}\pm
0.54){{GeV/}c^2}


title: Xic' Production at BABAR

abstract:
  Using 232 fb-1 of data collected by the BABAR detector, the Xic'+ and Xic'0
baryons are reconstructed through the decays: Xic'+ -> Xic+ gamma and Xic'0 ->
Xic0 gamma, where Xic+ -> Xi- pi+ pi+ and Xic0 -> Xi- pi+. By measuring the
efficiency-corrected yields in different intervals of the center-of-mass
momentum, the production rates from B decays and from the continuum are
extracted. For production from B decays, the branching fractions are found to
be B(B -> Xic'+ X) x B(Xic+ -> Xi- pi+ pi+) = [ 1.69 +- 0.17 (exp.) +- 0.10
(model) ] x 10^-4 and B(B -> Xic'0 X) x B(Xic0 -> Xi- pi+) = [ 0.67 +- 0.07
(exp.) +- 0.03 (model) ] x 10^-4. For production from the continuum the
cross-sections are found to be sigma(e+ e- -> Xic'+ X) x B(Xic+ -> Xi- pi+ pi+)
= 141 +- 24 (exp.) +- 19 (model) fb and sigma(e+ e- -> Xic'0 X) x B(Xic0 -> Xi-
pi+) = 70 +- 11 (exp.) +- 6 (model) fb. The helicity angle distributions of
Xic' decays are studied and found to be consistent with J = 1/2.


title: Charm Hadronic Decay Branching Fractions From CLEO-c

abstract:
  The CLEO-c experiment at the CESR e+ e- storage ring has collected data with
E_cm = 3.77 GeV and E_cm ~ 4.17 GeV to study the decays of charmed mesons. This
paper discusses results on the hadronic branching fractions of the D0, D+, and
Ds+.


title:
Observation of muon neutrino disappearance with the MINOS detectors and
  the NuMI neutrino beam

abstract:
  This letter reports results from the MINOS experiment based on its initial
exposure to neutrinos from the Fermilab NuMI beam. The rate and energy spectra
of charged current muon neutrino interactions are compared in two detectors
located along the beam axis at distances of 1 km and 735 km. With 1.27 x
10^{20} 120 GeV protons incident on the NuMI target, 215 events with energies
below 30 GeV are observed at the Far Detector, compared to an expectation of
336 \pm 14.4 events. The data are consistent with muon neutrino disappearance
via oscillation with |\Delta m^2_{23}| = 2.74^{+0.44}_{-0.26} x 10^{-3}
eV^2/c^4 and sin^2(2\theta_{23}) > 0.87 (at 60% C.L.).


title:
Measurement of the B -> pi l nu Branching Fraction and Determination of
  |Vub| with Tagged B Mesons

abstract:
  We report a measurement of the B -> pi l nu branching fraction based on 211
fb-1 of data collected with the BABAR detector. We use samples of B0 and B+
mesons tagged by a second B meson reconstructed in a semileptonic or hadronic
decay, and combine the results assuming isospin symmetry to obtain BF(B0 -> pi-
l+ nu) = (1.33 +/- 0.17(stat) +/- 0.11(syst)) x 10^-4. We determine the
magnitude of the Cabibbo-Kobayashi-Maskawa matrix element |Vub| by combining
the partial branching fractions measured in ranges of the momentum transfer
squared and theoretical calculations of the form factor. Using a recent lattice
QCD calculation, we find |Vub| = (4.5 +/- 0.5(stat) +/- 0.3(syst)
+0.7/-0.5(FF)) x 10^-3, where the last error is due to the normalization of the
form factor.


title: Search for D0--anti-D0 mixing in the decays D0 --> K+ pi- pi+ pi-

abstract:
  We present a search for D0--anti-D0 mixing in the decays D0 --> K+ pi- pi+
pi- using 230.4 fb-1 of data collected with the BaBar detector at the PEP-II e+
e- collider at SLAC. Assuming CP conservation, we measure the time-integrated
mixing rate R_M = (0.019 +0.016/-0.015(stat.) +/- 0.002(syst.))%, and R_M <
0.048% at the 95% confidence level. Using a frequentist method, we estimate
that the data are consistent with no mixing at the 4.3% confidence level. We
present results both with and without the assumption of CP conservation. By
combining the value of R_M from this analysis with that obtained from an
analysis of the decays D0 --> K+ pi- pi0, we find R_M = (0.020 +0.011/-0.010)%,
where the uncertainty is statistical only. We determine the upper limit R_M <
0.042% at the 95% confidence level, and we find the combined data are
consistent with the no-mixing hypothesis at the 2.1% confidence level.


title:
A measurement of CP-violation parameters in B0B0bar mixing using
  partially reconstructed D*- l+ nu_l events at BaBar

abstract:
  CP violation in B0B0bar mixing is characterized by the value of the parameter
|q/p| being different from 1, and the Standard Model predicts this difference
to be smaller than 10^{-3}. We present a measurement of this parameter using a
partial reconstruction of one of the B mesons in the semileptonic channel D*-
l+ nu_l, where only the hard lepton and the soft pion from the D*- --> D0bar
pi- decay are reconstructed. The flavor of the other B is determined by means
of lepton tagging. The determination of |q/p| is then performed with a fit to
the proper time difference of the two B decays. We use a luminosity of 200.8
fb^-1, collected at the Y(4S) resonance by the BaBar detector at the PEP-II
asymmetrical-energy e+e- collider, in the period 1999-2004. We obtain the
preliminary result:
  |q/p| - 1 = (6.5 +/- 3.4(stat.) +/- 2.0(syst.)) x 10^{-3}


title:
Measurements of branching fraction, polarization, and charge asymmetry
  of B+ --> rho+ rho0 and a search for B+ --> rho+ f0(980)

abstract:
  We measure the branching fraction, polarization and CP asymmetry of B+ ->
rho+rho0 decays and search for the decay B+ -> rho+f_0(980) based on a data
sample of 231.8 million Y(4S)->BB decays collected with the BaBar detector at
the SLAC PEP-II asymmetric-energy B factory. In B+ -> rho+rho0 decays we
measure B=(16.8+-2.2+-2.3)x10-6, f_L=0.905+-0.042+0.023-0.027, and
A_CP=-0.12+-0.13+-0.10, and find an upper limit on the branching fraction of B+
-> rho+f_0(980)(->pi+pi-) of 1.9x10-6 at 90% Confidence Level.


title: Inclusive Prompt Photon Production in Deep Inelastic Scattering at H1

abstract:
  Results are presented on the inclusive production of isolated prompt photons
in deep inelastic scattering with a four-momentum transfer of $Q^2>4 GeV^2$.
The cross sections are measured for the transverse momentum range of the
photons $3 < E_T^\gamma < 10 GeV$ and for the pseudorapidity range of the
photons $-1.2 < \eta^\gamma < 1.8$. They are measured differentially as a
function of $E_T^\gamma$ and $\eta^\gamma$. The results are compared with the
predictions of a leading order calculation, which is in reasonable agreement
with the inclusive measurement.


title:
Measurement of the Pseudoscalar Decay Constant fDs Using Charm-Tagged
  Events in e+e- Collisions at \sqrt{s}=10.58GeV

abstract:
  Using 230.2 fb^(-1) of e+e- annihilation data collected with the BABAR
detector at and near the peak of the Y(4S) resonance, 489 +/- 55 events
containing the pure leptonic decay D_s^+ --> mu^+ nu_mu have been isolated in
charm-tagged events. The ratio of partial widths Gamma(D_s^+ --> mu^+
nu_mu)/Gamma(D_s^+ --> phi pi^+) is measured to be 0.143 +/- 0.018 +/- 0.006
allowing a determination of the pseudoscalar decay constant f_{D_s} = (283 +/-
17 +/- 7 +/- 14) MeV. The errors are statistical, systematic, and from the
D_s^+ --> phi pi^+ branching ratio, respectively.


title:
Measurement of the ttbar Production Cross Section in ppbar collisions at
  sqrt s = 1.96 TeV in the All Hadronic Decay Mode

abstract:
  We report a measurement of the ttbar production cross section using the
CDF-II detector at the Fermilab Tevatron. The analysis is performed using 311
pb-1 of ppbar collisions at sqrt(s)=1.96 TeV. The data consist of events
selected with six or more hadronic jets with additional kinematic requirements.
At least one of these jets must be identified as a b-quark jet by the
reconstruction of a secondary vertex. The cross section is measured to be
sigma(tbart)=7.5+-2.1(stat.)+3.3-2.2(syst.)+0.5-0.4(lumi.) pb, which is
consistent with the standard model prediction.


title:
Measurement of the CP-violating Asymmetries in B0 -> KS pi0 and of the
  Branching Fraction of B0 -> K0 pi0

abstract:
  We present a measurement of the time-dependent CP-violating asymmetries in B0
-> K0S pi0 decays based on 348 million Y(4S) -> BBbar events collected by the
BABAR experiment at the PEP-II asymmetric-energy B Factory at SLAC. We measure
the direct CP-violating asymmetry C_{K0S pi0} = 0.20 +/- 0.16 +/- 0.03 and the
CP-violating asymmetry in the interference between mixing and decay S_{K0S pi0}
= 0.33 +/- 0.26 +/- 0.04 where the first error is statistical and the second
systematic. On the same sample, we measure the decay branching fraction,
obtaining B(B0 -> K0S pi0)= (10.5 +/- 0.7 +/- 0.5) 10^{-6}. All results
presented here are preliminary.


title:
Evidence for the B0->rho0rho0 Decay and Implications for the CKM Angle
  alpha

abstract:
  We search for the decays B0->rho0rho0, B0->rho0f0, and B0->f0f0 in a sample
of about 348 million Upsilon(4S)->BBbar decays collected with the BABAR
detector at the PEP-II asymmetric-energy e+e- collider at SLAC. We find
evidence for B0->rho0rho0 with 3.0 sigma significance and measure the branching
fraction B = (1.16 +0.37-0.36 +-0.27) 10^{-6} and longitudinal polarization
fraction f_L = 0.86 +0.11-0.13 +-0.05. As a consequence, the uncertainty on the
CKM unitarity angle alpha due to penguin contributions in B->rhorho decays is
estimated to be 18 degrees at 1 sigma level. We also set upper limits on the
B0->rho0f0 and B0->f0f0 decay rates. All results are preliminary.


title: Updated Measurement of the CKM Angle alpha Using B0->rho+rho- Decays

abstract:
  We present results from an analysis of B0->rho+rho- using 316fb^-1 of Y(4S)
-> B0B0bar decays observed with the BaBar detector at the PEP-II
asymmetric-energy B Factory at SLAC. We measure the B0->rho+rho- branching
fraction, longitudinal polarization fraction fL, and the CP-violating
parameters S_LONG and C_LONG:
  B(B0->rho+rho-) = (23.5 +/- 2.2 [stat] +/- 4.1 [syst]) * 10^-6, fL = 0.977
+/- 0.024 [stat] +0.015/-0.013 [syst]
  S_LONG = -0.19 +/- 0.21 [stat] +0.05/-0.07 [syst]
  C_LONG = -0.07 +/- 0.15 [stat] +/- 0.06 [syst]
  Using an isospin analysis of B->rhorho decays we determine the angle alpha of
the unitarity triangle. One of the two solutions, alpha = [74, 117] degrees at
68% CL, is compatible with the standard model. All results presented here are
preliminary.


title:
Measurement of the Branching Fractions for the Decays B+ -> rho+ gamma,
  B0 -> rho0 gamma, and B0 -> omega gamma

abstract:
  We present preliminary results of a search for the decays B+ -> rho+ gamma,
B0 -> rho0 gamma, and B0 -> omega gamma. The analysis is based on data
containing 347 million BB events recorded with the BaBar detector at the PEP-II
B factory. We measure branching fractions of BF(B+ -> rho+ gamma) =
(1.06^{+0.35}_{-0.31} +- 0.09) x 10^{-6} and BF(B+ -> rho0 gamma) =
(0.77^{+0.21}_{-0.19} +- 0.07) x 10^{-6}, where the first errors are
statistical and the second systematic, and set a 90% C.L. upper limit of BF(B0
-> omega gamma) < 0.84 10^{-6}. Assuming isospin relations between the three
branching fractions, these results are used to determine the CKM matrix element
ratio |V_td/V_ts| = 0.171^{+0.018}_{-0.021}(exp.)^{+0.017}_{-0.014}(theor.).


title: Time-dependent CP-violation parameters in B0->eta' K0 decay

abstract:
  We present measurements of time-dependent CP-violation asymmetries for the
decays B0 to eta'K0. The data sample corresponds to 347 million BBbar pairs
produced by e+e- annihilation at the Upsilon(4S) resonance in the PEP-II
collider, and collected with the BaBar detector. The preliminary results are S
= 0.55+/-0.11+/-0.002, and C = -0.15+/-0.07+/-0.03, where the first error
quoted is statistical, the second systematic.


title: Measurements of CP-Violating Asymmetries in B Decays to omegaKs

abstract:
  We present preliminary measurements of CP-violating asymmetries for the decay
omega K0S. The data sample corresponds to 347 million BBbar pairs produced by
e+e- annihilation at the Upsilon(4S) resonance. For the decay omega K0S, we
measure the time-dependent CP-violation parameters S = 0.62+0.25-0.30+/-0.002,
and C = -0.43+0.25-0.23+/-0.03, where the first uncertainty is statistical and
the second systematic.


title: Search for W' boson production in the W'->tb decay channel

abstract:
  We present a search for the production of a new heavy gauge boson W' that
decays to a top quark and a bottom quark. We have analyzed 230 pb^{-1} of data
collected with the Dzero detector at the Fermilab Tevatron collider at a
center-of-mass energy of 1.96 TeV. No significant excess of events above the
standard model expectation is found in any region of the final state invariant
mass distribution. We set upper limits on the production cross section of W'
bosons times branching ratio to top quarks at the 95% confidence level for
several different W' boson masses. We exclude masses between 200 GeV and 610
GeV for a W' boson with standard-model-like couplings, between 200 GeV and 630
GeV for a W' boson with right-handed couplings that is allowed to decay to both
leptons and quarks, and between 200 GeV and 670 GeV for a W' boson with
right-handed couplings that is only allowed to decay to quarks.


title:
Search for CPT and Lorentz Violation in B0-B0bar Oscillations with
  Inclusive Dilepton Events

abstract:
  We report preliminary results of a search for CPT and Lorentz violation in
B0-B0bar oscillations using an inclusive dilepton sample collected by the BABAR
experiment at the PEP-II B Factory. Using a sample of 232 million BBbar pairs,
we search for time-dependent variations in the complex CPT parameter z = z0 +
z1*cos(Omega*t^ + phi) where Omega is the Earth's sidereal frequency and t^ is
sidereal time. We measure Im(z0) = (-14.1 +- 7.3(stat) +- 2.4(syst)) x 10E-3,
DeltaGamma*Re(z0) = (-7.2 +- 4.1(stat) +- 2.1(syst)) x 10E-3 ps-1, Im(z1) =
(-24.0 +- 10.7(stat) +- 5.9(syst)) x 10E-3, and DeltaGamma*Re(z1) = (-18.8 +-
5.5(stat) +- 4.0(syst)) x 10E-3 ps-1, where DeltaGamma is the difference
between the decay rates of the neutral B mass eigenstates. The statistical
correlation between the measurements of Im(z0) and DeltaGamma*Re(z0) is 76%;
between Im(z1) and DeltaGamma*Re(z1) it is 79%. These results are used to
evaluate expressions involving coefficients for Lorentz and CPT violation in
the general Lorentz-violating standard-model extension. In a complementary
approach, we examine the spectral power of periodic variations in z over a wide
range of frequencies and find no significant signal.


title:
Measurement of the CKM angle gamma in B ->D(*)0K decays with a Dalitz
  analysis of D0->KS pi- pi+

abstract:
  We present a measurement of the Cabibbo-Kobayashi-Maskawa CP-violating phase
gamma with a Dalitz analysis of neutral D-meson decays to the K^0_s pi^- pi^+
final state from B^+/- -> D^{(*)}K^+/- decays, using a sample of 347 million
B\bar{B} events collected by the BaBar detector. We measure gamma = (92 +/- 41
+/- 11 +/- 12)deg, where the first error is statistical, the second is the
experimental systematic uncertainty and the third reflects the Dalitz model
uncertainty. For the ratios r_B^{(*)} between the magnitudes of amplitudes A(B-
-> D^{(*)0}K-) and A(B- ->\bar{D}^{(*)0} K-) we obtain the one-standard
deviation intervals [0,0.14] and [0.02,0.20], respectively. All results
presented here are preliminary.


title:
Measurement of cos(2beta) in B0 -> D(*)0 h0 decays with a time-dependent
  Dalitz plot analysis of D0 -> Ks pi+ pi-

abstract:
  We report a preliminary measurement of $\cos2\beta$ in $B^0\to D^{(*)0}h^0$
decays with a time-dependent Dalitz plot analysis of $D^0\to K_S\pi^+\pi^-$,
where $h^0$ is a light neutral meson such as $\pi^0$, $\eta$, $\eta'$ or
$\omega$. The strong phase variation on the Dalitz plot allows the access to
the angle $\beta$ with only a two-fold ambiguity ($\beta+\pi$). Using
$311\times 10^{6}$ $B\bar{B}$ pairs collected at the Babar detector, we obtain
$\cos2\beta = 0.54 \pm 0.54 \pm 0.08 \pm 0.18$, $\sin2\beta = 0.45 \pm 0.36 \pm
0.05 \pm 0.07$, and $|\lambda| = 0.975^{+0.093}_{-0.085} \pm 0.012 \pm 0.002 $,
where the first errors are statistical, the second are experimental systematic
uncertainties, and the third are the signal Dalitz model uncertainties. This
measurement favors the solution of $\beta= 22^\circ$ over $68^\circ$ at an 87%
confidence level.


title:
Measurement of CP Asymmetries and Branching Fractions in B -> pi pi and
  B -> K pi decays

abstract:
  We present preliminary measurements of the CP asymmetries and branching
fractions for B -> pi pi and B -> K pi decays. A total of 347 million BBbar
events collected by the BABAR detector at the PEP-II asymmetric-energy e+e-
collider at SLAC are used for these results. We find
  Spipi = -0.53 +- 0.14 +-0.02,
  Cpipi = -0.16 +- 0.11 +- 0.03,
  AKpi = -0.108 +- 0.024 +- 0.008,
  BF(B0 -> pi0 pi0) = (1.48 +- 0.26 +- 0.12) x 10^-6,
  BF(B+ -> pi+pi0) = (5.12 +- 0.47 +- 0.29) x 10^-6,
  BF(B+ -> K+pi0) = (13.3 +- 0.56 +- 0.64) x 10^-6,
  Cpi0pi0 = -0.33 +- 0.36 +- 0.08,
  Apipi0 = -0.019 +- 0.088 +- 0.014,
  AKpi0 = 0.016 +- 0.041 +- 0.012.
  The measured values of Spipi and Cpipi imply that CP conservation in B0 ->
pi+ pi- decays is excluded at the 3.6 sigma level. From these results we
present bounds on the CKM angle alpha.


title:
Improved Measurement of CP Asymmetries in $\Bz \to (\ccbar) K^{(*)0}$
  Decays

abstract:
  We present an updated measurements of time-dependent CP asymmetries in fully
reconstructed neutral B decays to several CP eigenstates containing a
charmonium meson. The measurements use a data sample of (347.5 +/- 3.8) x
10^{6} $\FourS \to B\Bbar$ decays collected with the babar detector at the
PEP-II B factory between 1999 and 2006. We determine sin2beta = 0.710 +/-
0.034(stat) +/- 0.019(syst) and |\lambda| = 0.932 +/- 0.026(stat) +/-
0.017(syst). Both of these results are preliminary.


title: Measurement of Time-dependent CP Asymmetries in B0 -> K0S K0S K0S Decay

abstract:
  We present an updated measurement of the time-dependent CP-violating
asymmetry in B0->K0S K0S K0S decays based on 347 million Upsilon(4S)->B Bbar
decays collected with the BABAR detector at the PEP-II asymmetric-energy B
factory at SLAC. We obtain the CP asymmetries S_f = -0.66 +/- 0.26 +/- 0.08 and
C_f = -0.14 +/- 0.22 +/- 0.05, where the first uncertainties are statistical
and the second systematic.


title: Observation of B --> eta' K* and Evidence for B --> eta' rho+

abstract:
  We present an observation of $B\to\eta^\prime K^*$. The data sample
corresponds to 232 million $B\bar{B}$ pairs collected with the BABAR detector
at the PEP-II asymmetric-energy $B$ Factory at SLAC. We measure the branching
fractions (in units of $10^{-6}$) $\mathcal{B}(B^0\to\eta^\prime K^{*0}) =
3.8\pm1.1\pm0.5$ and $\mathcal{B}(B^+\to\eta^\prime K^{*+}) =
4.9^{+1.9}_{-1.7}\pm0.8$, where the first error is statistical and the second
systematic. A simultaneous fit results in the observation of $B\to\eta^\prime
K^*$ with $\mathcal{B}(B\to\eta^\prime K^*) = 4.1_{-0.9}^{+1.0} \pm 0.5$. We
also search for $B\to\eta^\prime \rho$ and $B\to\eta^\prime f_0(980)(f_0 \to
\pi^+\pi^-)$ with results and 90% confidence level upper limits
$\mathcal{B}(B^+\to\eta^\prime \rho^+) = 8.7^{+3.1}_{-2.8}{} ^{+2.3}_{-1.3}$
($<14$), $\mathcal{B}(B^0\to\eta^\prime \rho^0) < 3.7$ and
$\mathcal{B}(B^0\to\eta^\prime f_0(980)(f_0\to\pi^+\pi^-)) < 1.5$. Charge
asymmetries in the channels with significant yields are consistent with zero.


title:
A search for the decays $B^+\to e^+ \nu_e$ and $B^+\to \mu^+ \nu_\mu$
  using hadronic-tag reconstruction

abstract:
  We report on a search for the rare decay modes $B^+\to e^+ \nu_e$ and $B^+\to
\mu^+ \nu_\mu$ with data collected from the BaBar detector at the PEP-II
$e^+e^-$ storage ring. This search utilizes a new technique in which we fully
reconstruct the accompanying $B^-$ in $\Upsilon(4S)\righarrow B^+ B^-$ events,
and look for a mono-energetic lepton in the $B^+$ rest frame. No signal
candidates are observed in either of the channels, consistent with the expected
background, in a data sample of approximately 229 million $B\bar{B}$ pairs. The
branching-fraction upper limits are set at $\mathcal{B}(B^+\to e^+\nu_{e})<7.9
\times 10^{-6}$ and $\mathcal{B}(B^+\to\mu^+\nu_{\mu})<6.2 \times 10^{-6}$ at
the 90% confidence level.


title:
Measurement of the Ratio ${\cal B}\xspace(\B^+ \to X e \nu)$ / ${\cal
  B}\xspace(\B^0 \to X e \nu)

abstract:
  We report measurements of the inclusive electron momentum spectra in decays
of charged and neutral B mesons, and of the ratio of semileptonic branching
fractions ${\cal B}\xspace(\B^+ \to X e \nu)$ and ${\cal B}\xspace(\B^0 \to X e
\nu)$. These were performed on a sample of 231 million $B\kern 0.18em\bar{\kern
-0.18em B}{}\xspace$ events recorded with the \mbox{\slshape
B\kern-0.1em{\smaller A}\kern-0.1em B\kern-0.1em{\smaller A\kern-0.2em R}}
detector at the $\Upsilon{(4S)}\xspace$ resonance. Events are selected by fully
reconstructing a hadronic decay of one $B$ meson and identifying an electron
among the decay products of the recoiling $\Bbar$ meson. We obtain ${\cal
B}\xspace(\Bu \to X e \nu)$/${\cal B}\xspace(\Bz \to X e \nu)$ = $1.084 \pm
0.041_{\mathrm{(stat)}}\xspace\pm 0.025_{\mathrm{(syst)}}\xspace$.


title: Measurement of CP-Violating Asymmetries in the B0->K+K-K0 Dalitz Plot

abstract:
  We present a preliminary measurement of CP-violation parameters in the decay
B0 -> K+K-K0, using approximately 347 million BBbar events collected by the
BABAR detector at SLAC. Reconstructing the neutral kaon as KS -> pi+pi-, KS ->
pi0pi0, or KL, we analyze the Dalitz plot distribution and measure fractions to
intermediate states. We extract CP parameters from the asymmetries in
amplitudes and phases between B0 and B0bar decays across the Dalitz plot. For
decays to phiK0, we find beta_eff=0.06 +/- 0.16 +/- 0.05, Acp=-0.18 +/- 0.20
+/- 0.10, where the first uncertainty is statistical and the second one is
systematic. For decays to f0K0, we find beta_eff=0.18 +/- 0.19 +/- 0.04,
Acp=0.45 +/- 0.28 +/- 0.10. Combining all KKK0 events and taking account of the
different CP eigenvalues of the individual Dalitz plot components, we find
beta_eff = 0.361 +/- 0.079 +/- 0.037, Acp = -0.034 +/- 0.079 +/- 0.025. The
trigonometric reflection at pi/2 - beta_eff is disfavored at 4.6 sigma. We also
study angular distributions in B0 -> K+K-KS and B+ -> phi K+ decays and measure
the direct CP asymmetry in B+ -> phi K+ decays, Acp = 0.046 +/- 0.046 +/-
0.017.

Branching Fraction Measurements of Charged B Decays to K*+K+K-,
  K*+pi+K-, K*+K+pi- and K*+pi+pi- Final States

abstract:
  Branching fraction and asymmetry measurements of charmless $B^+\to
K^{*+}h^+_1h^-_2$ (where $h_{1,2}$ = $K$, $\pi$) decays are presented, using a
data sample of 232 million $\Upsilon(4S) \to$ $BB$ decays collected with the
BaBar detector at the SLAC PEP-II asymmetric-energy $B$ factory. Using a
maximum likelihood fit, the following branching fraction results were obtained:
${\cal B}$($B^+ \to K^{*+}K^+ K^-)$ = (36.2 $\pm$ 3.3 $\pm$ 3.6) $\times$
10$^{-6}$ and ${\cal B}$($B^+$ $\to$ $K^{*+}\pi^+\pi^-$) = (75.3 $\pm$ 6.0
$\pm$ 8.1) $\times$ 10$^{-6}$. Upper limits were set for ${\cal B}$($B^+$ $\to$
$K^{*+}\pi^+ K^-$) $<$ 11.8 $\times$ 10$^{-6}$ and ${\cal B}$($B^+$ $\to$
$K^{*+}K^+ \pi^-$) $<$ 6.1 $\times$ 10$^{-6}$ at 90% confidence level. The
charge asymmetries for the decays $B^+ \to K^{*+}K^+ K^-$ and $B^+$ $\to$
$K^{*+}\pi^+\pi^-$ were measured to be ${\cal A}_{K^*KK} = 0.11 \pm 0.08 \pm
0.03$ and ${\cal A}_{K^*\pi\pi} = 0.07 \pm 0.07 \pm 0.04$, respectively. The
first error quoted on branching fraction and asymmetry measurements is
statistical and the second systematic.


title: Machine-Related Backgrounds in the SiD Detector at ILC

abstract:
  With a multi-stage collimation system and magnetic iron spoilers in the
tunnel, the background particle fluxes on the ILC detector can be substantially
reduced. At the same time, beam-halo interactions with collimators and
protective masks in the beam delivery system create fluxes of muons and other
secondary particles which can still exceed the tolerable levels for some of the
ILC sub-detectors. Results of modeling of such backgrounds in comparison to
those from the e+ e- interactions are presented in this paper for the SiD
detector.


title:
Measurement of CP-Violating Asymmetries in $B^0\to(\rho\pi)^0$ Using a
  Time-Dependent Dalitz Plot Analysis

abstract:
  We report a measurement of CP-violating asymmetries in
$B^0\to(\rho\pi)^0\to\pi^+\pi^-\pi^0$ decays using a time-dependent Dalitz plot
analysis. The results are obtained from a data sample of 347 million
$\Upsilon(4S) \to B\bar{B}$ decays, collected by the BaBar detector at the
PEP-II asymmetric-energy B Factory at SLAC. We measure 26 coefficients of the
bilinear form factor terms occurring in the time-dependent decay rate of the
\Bz meson and derive the physically relevant quantities from these
coefficients. In particular we find a three standard deviation evidence of
direct CP-violation in $B^0\to\rho^\pm\pi^\mp$ decays, with systematic
uncertainties included. We also achieve a constraint of the angle $\alpha$ of
the Unitarity Triangle. All results presented are preliminary.


title:
Improved Measurements of the Branching Fractions for B0 --> pi+pi- and
  B0 --> K+pi-, and a Search fro B0 --> K+K-

abstract:
  We present measurements of the branching fractions for the charmless two-body
decays $\Bz\to\pip\pim$ and $\Bz\to\Kp\pim$, and a search for the decay
$\Bz\to\Kp\Km$. We include the effects of final-state radiation from the
daughter mesons for the first time, and quote branching fractions for the
inclusive processes $\Bz\to h^+ h^{\prime -} n\gamma$, where $h$ and $h^\prime$
are pions or kaons. The maximum value of the sum of the energies of the $n$
undetected photons, $E_\gamma^{\rm max}$, is mode-dependent. Using a data
sample of approximately 227 million \upsbb decays collected with the \babar\
detector at the \pep2 asymmetric-energy \epem collider at SLAC, we measure:
\begin{eqnarray*} {\cal B} (\Bz \to \pip\pim n\gamma;\: E_{\gamma}^{\rm
max}=150\mev) & = & (5.1\pm 0.4\pm 0.2)\times 10^{-6}, {\cal B} (\Bz \to
\Kp\pim n\gamma;\: E_{\gamma}^{\rm max}=105\mev) & = & (18.1\pm 0.6\pm
0.6)\times 10^{-6}, {\cal B} (\Bz \to \Kp\Km n\gamma;\: E_{\gamma}^{\rm
max}=59\mev) & < & 0.5 \times 10^{-6} (90% {\rm confidence level}),
\end{eqnarray*} where the first uncertainty is statistical and the second is
systematic. Theoretical calculations can be used to extrapolate from the above
measurements the non-radiative branching fractions, ${\cal B}^0$. Using one
such calculation, we find: \begin{eqnarray*} {\cal B}^0 (\Bz \to \pip\pim) & =
& (5.5\pm 0.4\pm 0.3)\times 10^{-6}, {\cal B}^0 (\Bz \to \Kp\pim) & = &
(19.1\pm 0.6\pm 0.6)\times 10^{-6}, {\cal B}^0 (\Bz \to \Kp\Km) & < & 0.5
\times 10^{-6} (90% {\rm confidence level}). \end{eqnarray*} Meaningful
comparison between theory and experiment, as well as combination of
measurements from different experiments, can be performed only in terms of
these non-radiative quantities.


title:
Search for Charmonium States Decaying to J/psi gamma gamma Using
  Initial-State Radiation Events

abstract:
  We study the processes e+e- -> (J/psi gamma gamma) gamma and e+e- -> (J/psi
pi- pi+) gamma where the hard photon radiated from an initial e+e- collision
with center-of-mass (CM) energy near 10.58 GeV is detected. In the final state
J/psi gamma gamma we consider J/psi pi0, J/psi eta, chi_{c1} gamma, and
chi_{c2} gamma candidates. The invariant mass of the hadronic final state
defines the effective e+e- CM energy in each event, so these data can be
compared with direct e+e- measurements. We report 90% CL upper limits for the
integrated cross section times branching fractions of the J/psi gamma gamma
channels in the Y(4260) mass region.


title:
Measurement of branching fractions and charge asymmetries in B decays to
  an eta meson and a K* meson

abstract:
  We present measurements of branching fractions and charge asymmetries for the
decays etaK*, where K* indicates a spin 0, 1, or 2 Kpi system. The data sample
corresponds to 344x10^6 BBbar pairs collected with the BABAR detector at the
PEP-II asymmetric-energy e+e- collider at SLAC. We measure the branching
fractions (in units of 10^-6): BR(B0->etaK*0)=16.5\pm1.1\pm0.8,
BR(B+->etaK*+)=18.9\pm1.8\pm1.3, BR(B0->eta(Kpi)_0*0)=11.0\pm1.6\pm1.5,
BR(B+->eta(Kpi)_0*+)=18.2\pm2.6\pm 2.6, BR(B0->etaK_2*0(1430))=9.6\pm1.8\pm1.1,
and BR(B+->etaK_2*+(1430))=9.1\pm2.7\pm 1.4. We also determine the charge
asymmetries for all decay modes.


title:
Search for D0--anti-D0 Mixing and Branching-Ratio Measurement in the
  Decay D0 --> K+ pi- pi0

abstract:
  We analyze 230.4 fb-1 of data collected with the BaBar detector at the PEP-II
e+ e- collider at SLAC to search for evidence of D0--anti-D0 mixing using
regions of phase space in the decay D0 --> K+ pi- pi0. We measure the
time-integrated mixing rate R_M = (0.023 +0.018/-0.014(stat.) +/-
0.004(syst.))%, and R_M < 0.054% at the 95% confidence level, assuming CP
invariance. The data are consistent with no mixing at the 4.5% confidence
level. We also measure the branching ratio for D0 --> K+ pi- pi0 relative to D0
--> K- pi+ pi0 to be (0.214 +/- 0.008(stat.) +/- 0.008(syst.))%.


title: Cascade and anti-Cascade Polarization Measurements at 800 GeV/c

abstract:
  The polarization of neutral Cascade and anti-Cascade hyperons produced by 800
GeV/c protons on a BeO target at a fixed targeting angle of 4.8 mrad is
measured by the KTeV experiment at Fermilab. Our result of 9.7% for the neutral
Cascade polarization shows no significant energy dependence when compared to a
result obtained at 400 GeV/c production energy and at twice our targeting
angle. The polarization of the neutral anti-Cascade is measured for the first
time and found to be consistent with zero. We also examine the dependence of
polarization on transverse production momentum.


title: Charm Dalitz analyzes from CLEO-c

abstract:
  I discuss CLEO-c opportunities in Dalitz plot analyzes with the data samples
available now and projected by the end of CESR-c run. Using 281 pb$^{-1}$ of
$e^+e^-$ collisions at mass of $\psi(3770)$ we present results of the Dalitz
plot analysis of $D^+ \to \pi^-\pi^+\pi^+$. Using the CLEO-c and CLEO III
samples of 5 pb$^{-1}$, accrued at mass of $\psi(2S)$, we study three body
decays of $\chi_{cJ}$ produced in the radiative decay $\psi(2S) \to \gamma
\chi_{cJ}$, where $J$=0,1,2. A clear signal from at least one of $\chi_{cJ}$ is
found in eight final states: $\pi^+\pi^-\eta$, $\pi^+\pi^-\eta^\prime$,
$K^+K^-\pi^0$, $K^0_S K \pi$, $\eta K^+K^-$, $\pi^0 p\bar{p}$, $\eta p\bar{p}$,
and $\Lambda K^+\bar{p}$. For these modes we measured or set an upper limit on
the branching fraction. A Dalitz plot analysis is performed on three modes
$\chi_{c1} \to \pi^+\pi^-\eta$, $K^+K^-\pi^0$, and $K^0_S K \pi$.


title:
Precise Branching Ratio Measurements of the Decays D0-->pi- pi+ pi0 and
  D0-->K- K+ pi0

abstract:
  Using 232 fb-1 of e+e- collision data recorded by the BaBar experiment, we
measure the ratios of three-body Cabibbo-suppressed decay rates of the D^0
meson relative to that of the Cabibbo-favored decay:
  B(D0 --> pi- pi+ pi0)/ B(D0 --> K- pi+ pi0) = (10.59 +/- 0.06 +/-
0.13).10^{-2} and B(D0 --> K- K+ pi0)/ B(D0 --> K- pi+ pi0) = (2.37 +/- 0.03
+/- 0.04). 10^{-2}, where the errors are statistical and systematic
respectively. The precisions of these measurements are significantly better
than those of the current world average values.We note that the second result
differs significantly from the current world average value. Using the PDG-2006
value for D0 --> K- pi+ pi0 branching fraction, we obtain, B(D0 --> pi- pi+
pi0) = (1.493 +/- 0.008 +/- 0.018 +/- 0.053). 10^{-2}, B(D0 --> K- K+ pi0) =
(0.334 +/- 0.004 +/- 0.006 +/- 0.012). 10^{-2}, where the errors are
statistical, systematic, and due to the uncertainty of B(D0 --> K- pi+ pi0).
The average squared matrix elements for both of the singly Cabibbo-suppressed
decays are roughly a factor of sin^2 \theta_C smaller than that for the
Cabibbo-favored decay and are therefore, in contrast to the corresponding
two-body modes, consistent with the naive expectations.


title:
Search for tribaryon production in alpha-particles interactions with
  protons at intermediate energies

abstract:
  The analysis of the data on the reactions $^4$Hep -> pppnn and $^4$Hep ->
dppn obtained at the 2-m ITEP liquid-hydrogen bubble chamber exposed to beams
of $^4$He nuclei with momenta of 2.7 and 5 GeV/c revealed a narrow structures
in the effective-mass spectra of the trinucleon system (NNN) at 2.99 GeV (for
isospin T=3/2) as well as at 3.04 GeV (T=1/2). The masses of the observed
structures are consistent with the masses of low-lying tribaryon resonances
predicted by some theoretical models. Possible resonance nature of the
structures observed is discussed.


title:
Limits on anomalous trilinear gauge couplings from WW->e+e-, WW->emu,
  and WW->mu+mu- events from p-pbar collisions at sqrt(s)=1.96 TeV

abstract:
  Limits are set on anomalous WWgamma and WWZ trilinear gauge couplings using
W+W- -> e+e-, W+W- -> e mu, and W+W- -> mu+mu- events. The data set was
collected by the Run II D0 detector at the Fermilab Tevatron Collider and
corresponds to approximately 250 inverse pb of integrated luminosity at sqrt(s)
= 1.96 TeV. Under the assumption that the WWgamma couplings are equal to the
WWZ couplings and using a form factor scale of Lambda = 2.0 TeV, the combined
95% C.L. one-dimensional coupling limits from all three channels are -0.32 <
Delta kappa < 0.45 and -0.29 < lambda < 0.30.


title: Measurement of masses of $\Xi_c(2645)$ and $\Xi_c(2815)$ baryons

abstract:
  We report a precise measurement of masses of the $\Xi_c(2645)$ and
$\Xi_c(2815)$ baryons using data collected by the Belle experiment at the KEKB
$e^+ e^-$ collider. The states $\Xi_c(2645)^{0,+}$ are observed in the
$\Xi_c^{+,0}\pi^{-,+}$ decay modes, while the $\Xi_c(2815)^{0,+}$ are
reconstructed in the $\Xi_c(2645)^{+,0}\pi^{-,+}$ decay modes.


title:
Search for pair production of scalar bottom quarks in ppbar collisions
  at sqrt(s)=1.96 TeV

abstract:
  A search for direct production of scalar bottom quarks (sb) is performed with
310 pb-1 of data collected by the DO experiment in ppbar collisions at
sqrt(s)=1.96 TeV at the Fermilab Tevatron Collider. The topology analyzed
consists of two b jets and an imbalance in transverse momentum due to
undetected neutralinos chi0_1, with chi0_1 assumed to be the lightest
supersymmetric particle. We find the data consistent with standard model
expectations, and set a 95% C.L. exclusion domain in the (m_sb,m_chi0_1) mass
plane, improving significantly upon the results from Run I of the Tevatron.


title:
Measurement of neutral current cross sections at high Bjorken-x with the
  ZEUS detector at HERA

abstract:
  A new method is employed to measure the neutral current cross section up to
Bjorken-x values of one with the ZEUS detector at HERA using an integrated
luminosity of 65.1 pb-1 for e+p collisions and 16.7 pb-1 for e-p collisions at
sqrt{s}=318 GeV and 38.6 pb-1 for e+p collisions at sqrt{s}=300 GeV. Cross
sections have been extracted for Q2 >= 648 GeV2 and are compared to predictions
using different parton density functions. For the highest x bins, the data have
a tendency to lie above the expectations using recent parton density function
parametrizations.


title:
Measurement of inclusive $D_s$, $D^0$, and $J/\psi$ rates and
  determination of the $B_s^{(*)} \bar{B}_s^{(*)}$ production fraction in $b
  \bar{b}$ events at the Y(5S) resonance

abstract:
  The inclusive production of $D_s$, $D^0$, and $J/\psi$ mesons is studied
using a 1.86 fb$^{-1}$ data sample collected on the $\Upsilon$(5S) resonance by
the Belle detector at the KEKB asymmetric energy $e^+ e^-$ collider. The number
of $b\bar{b}$ events in the $\Upsilon$(5S) data sample is determined. We
measure the branching fractions $B(\Upsilon({\rm 5S}) \to D_s X) / 2 = (23.6
\pm 1.2 \pm 3.6)%$, $B(\Upsilon({\rm 5S}) \to D^0 X) / 2 = (53.8 \pm 2.0 \pm
3.4)%$}, and $B(\Upsilon({\rm 5S}) \to J/\psi X) / 2 = (1.030 \pm 0.080 \pm
0.067)%$. From the $D_s$ and $D^0$ inclusive branching fractions the ratio $f_s
= (18.0 \pm 1.3 \pm 3.2)%$} of $B_s^{(*)} \bar{B}_s^{(*)}$ to the total
$b\bar{b}$ quark pair production at the $\Upsilon$(5S) energy is obtained in a
model-dependent way.


title:
Measurement of the Branching Fraction and Time-Dependent CP Asymmetry in
  the Decay B0->D*+D*-Ks

abstract:
  We study the decay B0->D*+D*-Ks using (230 +/- 2) x 10^{6} BBbar pairs
collected by the Babar detector at the PEP-II B factory. We measure a branching
fraction B(B0->D*+D*-Ks)=(4.4\pm0.4\pm0.7)\times 10^{-3} and find evidence for
the decay B0->D*- D+_{s1}(2536) with a significance of $4.6\sigma$. A
time-dependent CP asymmetry analysis is also performed to study the possible
resonant contributions to B0->D*+D*-Ks and the sign of cos2beta . Our
measurement indicates that there is a sizable resonant contribution to the
decay B0->D*+D*-Ks from a unknown $D^+_{s1}$ state with large width, and that
cos2beta is positive at the 94 % confidence level under certain theoretical
assumptions.


title: Time-Dependent CP Asymmetries in B0 -> Ks pi0 gamma transitions

abstract:
  We report measurements of CP violation parameters in B0->Ks pi0 gamma
transitions based on a data sample of 535x10^6 BB pairs collected with the
Belle detector at the KEKB asymmetric-energy e+ e- collider. One neutral B
meson is fully reconstructed in the B0->Ks pi0 gamma mode. The flavor of the
accompanying B meson is identified from its decay products. For a Ks pi0
invariant mass up to 1.8 GeV/c^2, we obtain S = -0.10 +- 0.31 +- 0.07 and A =
-0.20 +- 0.20 +- 0.06. For a Ks pi0 invariant mass near the K*0(892) resonance,
we obtain S = -0.32 +0.36-0.33 +-0.05 and A=-0.20 +-0.24 +-0.05.


title:
Measurement of the near-threshold $e^+e^- \to D^{(*)\pm}{D}{}^{*\mp}$
  cross section using initial-state radiation

abstract:
  We report a measurement of the exclusive $e^+e^- \to D^{(*)\pm}{D}{}^{*\mp}$
cross section as a function of center-of-mass energy near the
$D^{(*)^{\pm}}{D}{}^{*\mp}$ threshold with initial state radiation. A partial
reconstruction technique is used to increase the efficiency and to suppress
background. The analysis is based on a data sample collected with the Belle
detector at the $\Upsilon(4S)$ resonance and nearby continuum with an
integrated luminosity of 547.8 $\mathrm{fb}^{-1}$ at the KEKB asymmetric-energy
$e^+ e^-$ collider.


title: A Search for B+ --> tau+ nu Recoiling Against B- --> D0 l- nubar X

abstract:
  We present a search for the decay $B^{+} \to \tau^{+} \nu_{\tau}$ using 288
fb-1 of data collected at the $\Upsilon(4S)$ resonance with the BaBar detector
at the SLAC PEP-II $B$-Factory. A sample of events with one reconstructed
semileptonic B decay is selected, and in the recoil a search for $B^{+} \to
\tau^{+} \nu_{\tau}$ signal is performed. The $\tau$ is identified in the
following channels: {\tau^+ \to e^+ \nu_e \nutb}, {\tau^+ \to \mu^+ \nu_{\mu}
\nutb}, {\tau^+ \to \pi^+ \nutb} and {\tau^+ \to \pi^+ \pi^0 \nutb}. We measure
a branching fraction of $\mathcal{B}(B^{+} \to \tau^{+}
\nu_{\tau})=(0.88^{+0.68}_{-0.67}({stat.}) \pm 0.11 ({syst.})) \times 10^{-4}$
and extract an upper limit on the branching fraction, at the 90% confidence
level, of $\mathcal{B}(B^{+} \to \tau^{+} \nu_{\tau}) < 1.8 \times 10^{-4}$. We
calculate the product of the $B$ meson decay constant and $|\Vub|$ to be
$f_{B}\cdot|\Vub| =
(7.0^{+2.3}_{-3.6}({stat.})^{+0.4}_{-0.5}({syst.}))\times10^{-4}$ GeV \.


title:
Measurement of the B0 -> Lambda-bar p pi Branching Fraction and Study of
  the Decay Dynamics

abstract:
  We present a measurement of the B0 -> Lambda-bar p pi branching fraction
performed using the BaBar detector at the PEP-II asymmetric energy e+e-
collider. Based on a 232 million BB-bar pairs data sample we measure:
  BR(B0 -> Lambda-bar p pi) = [ 3.30 +- 0.53 (stat.) +- 0.31(syst.) ] x 10^-6.
  A measurement of the differential spectrum as a function of the di-baryon
invariant mass m(Lambda p) is also presented; this shows a near-threshold
enhancement similar to that observed in other baryonic B decays.


title: Jets at CDF

abstract:
  Recent jet results in $p\bar{p}$ collisions at $\sqrt{s}$=1.96 TeV from the
CDF experiment at the Tevatron are presented. The jet inclusive cross section
is compared to next-to-leading order QCD prediction in different rapidity
regions. The $b$-jet inclusive cross section is measured exploiting the long
lifetime and large mass of $B$-hadrons. Jet shapes, W+jets and W/Z+photon cross
sections are also measured and compared to expectations from QCD production.


title: STAR results on longitudinal spin dynamics

abstract:
  We present preliminary results on the double longitudinal spin asymmetries
A_LL in inclusive jet production and the longitudinal spin transfer asymmetries
D_LL in inclusive Lambda and anti-Lambda hyperon production. The data amount to
about 0.5 pb-1 collected at RHIC in 2003 and 2004 with beam polarizations up to
45 %. The jet A_LL asymmetries, measured over 5 < pT < 17 GeV/c, are consistent
with evaluations based on deep-inelastic scattering parametrizations for the
gluon polarization in the nucleon, and disfavor large positive values of gluon
polarization in the nucleon. The Lambda and anti-Lambda D_LL, measured at
midrapidity and at low average transverse momentum of 1.5 GeV/c, are consistent
with zero within their dominant statistical uncertainties.


title:
Proposal for an Experimental Program in Neutrino Physics and Proton
  Decay in the Homestake Laboratory

abstract:
  This report is intended to describe first, the principal physics reasons for
an ambitious experimental program in neutrino physics and proton decay based on
construction of a series of massive water Cherenkov detectors located deep
underground (4850 ft) in the Homestake Mine of the South Dakota Science and
Technology Authority (SDSTA); and second, the engineering design of the
underground chambers to house the Cherenkov detector modules; and third, the
conceptual design of the water Cherenkov detectors themselves for this purpose.
Included in this document are preliminary costs and time-to-completion
estimates which have been exposed to acknowledged experts in their respective
areas. We have included some contingency factors. Nevertheless, we recognize
that much more extensive documentation and contingency estimates will be needed
for a full technical design report.
  In this proposal we show the event rates and physics sensitivity for beams
from both FNAL (1300 km distant from Homestake) and BNL (2540 km distant from
Homestake). The program we propose will benefit from a beam from FNAL because
of the high intensities currently available from the Main Injector with modest
upgrades. The possibility of tuning the primary proton energy over a large
range from 30 to 120 GeV also adds considerable flexibility to the program from
FNAL.

title:
Study of the charmed baryonic decays
  $\bar{B}^0\to\Sigma_c^{++}\bar{p}\pi^-$ and
  $\bar{B}^0\to\Sigma_c^{0}\bar{p}\pi^+$

abstract:
  We study the three-body charmed baryonic decays $\bar{B}^0\to\Sigma_c^{++}
\bar{p}\pi^-$ and $\bar{B}^0\to\Sigma_c^{0}\bar{p}\pi^+$ in the four-body final
state $\bar{B}^0\to\Lambda_c^{+}\bar{p}\pi^+\pi^-$, using a data sample of 357
fb$^{-1}$ accumulated at the $\Upsilon(4S)$ resonance with the Belle detector
at the KEKB asymmetric-energy $e^+e^-$ collider. We measure the branching
fractions ${\cal B}
(\bar{B}^0\to\Sigma_c(2455)^{++}\bar{p}\pi^-)$=$(2.1\pm0.2\pm0.3\pm0.5)\times
10^{-4}$, ${\cal
B}(\bar{B}^0\to\Sigma_c(2455)^{0}\bar{p}\pi^+)$=$(1.4\pm0.2\pm0.2\pm0.4)\times1
0^{-4}$, ${\cal B}(\bar{B}^0\to\Sigma_c(2520)^{++}
\bar{p}\pi^-)$=$(1.2\pm\0.1\pm0.2\pm0.3)\times10^{-4}$ with statistical
significances of 13.1, 9.5 and 7.2 standard deviations, respectively. The
errors are statistical, systematic, and due to the uncertainty in ${\cal
B}(\Lambda_c^+\to{p}K^-\pi^+)$, respectively. We also set an upper limit ${\cal
B}(\bar{B}^0\to\Sigma_c(2520)^{0}\bar{p}\pi^+)<0.38\times10^{-4}$ at the 90%
confidence level. In addition, we obtain a non-resonant branching fraction of
$(6.4\pm0.4\pm\0.9\pm1.7)\times10^{-4}$, and a total branching fraction of
$(11.2\pm0.5\pm1.4\pm2.9)\times10^{-4}$ for
$\bar{B}^0\to\Lambda_c^{+}\bar{p}\pi^+\pi^-$.


title: The first observation of $\tau^{\pm} \to \phi K^{\pm} \nu$ decay

abstract:
  We present the first measurement of tau-decays to hadronic final states with
a $\phi$-meson. This is based on 401.4 fb$^{-1}$ of data accumulated at the
Belle experiment. The branching ratio obtained is $B(\tau^{\pm}\to\phi
K^{\pm}\nu) = (4.06\pm 0.25\pm 0.26)\times 10^{-5}$.


title: Measurement of stopping beam distributions in the PIBETA detector

abstract:
  Precise calculation of the geometrical acceptance of a large solid angle
detector with an integrated stopping target relies on precise knowledge of the
beam geometry. We describe four alternative methods that we used to measure the
beam stopping distributions in the PIBETA detector active target: (i) light
response of segmented target elements to incident beam particles, (ii)
back-tracking of charged particles from pi+ and mu+ decays using multi-wire
proportional chambers, (iii) volume distribution of the Dalitz decay
(pi0->gamma e+e-) event vertices, and (iv) the opening angle distribution of
two pi0 photons originating from the beta decay of pi+ at rest. We demonstrate
consistent results obtained by these four independent approaches and show how
particular beam stopping distributions affect the detector's geometrical
acceptance.


title:
Measurement of prompt photons with associated jets in photoproduction at
  HERA

abstract:
  The photoproduction of prompt photons, together with an accompanying jet, has
been studied in ep collisions at a centre-of-mass energy of 318 GeV with the
ZEUS detector at HERA using an integrated luminosity of 77 pb-1. Cross sections
were measured for the transverse energy of the photon and the jet larger than 5
and 6 GeV, respectively. The differential gamma+jet cross sections were
reconstructed as functions of the transverse energy, pseudorapidity and
x_gamma^obs, the fraction of the incoming photon momentum taken by the
photon-jet system. Predictions based on leading-logarithm parton-shower Monte
Carlo models and next-to-leading-order (NLO) QCD generally underestimate the
cross sections for the transverse energies of prompt photons below 7 GeV, while
the kT-factorisation QCD calculation agrees with the data better. When the
minimum transverse energy of prompt photons is increased to 7 GeV, both NLO QCD
and the kT-factorisation calculations are in good agreement with the data.


title:
Indication for $\pi^+ \pi^-$ scattering in $p+p$ collisions at
  $\sqrt{s_{_{NN}}} = $200 GeV

abstract:
  A $\rho(770)^0$ mass shift of about -40 MeV/$c^2$ was measured in $p+p$
collisions at $\sqrt{s_{_{NN}}} = $ 200 GeV at RHIC. Previous mass shifts have
been observed at CERN-LEBC-EHS and CERN-LEP. We will show that phase space does
not account for the $\rho(770)^0$ mass shift measured at RHIC, CERN-LEBC-EHS
and CERN-LEP and conclude that there are significant scattering interactions in
$p+p$ collisions.
