Longitudinal double-spin asymmetry and cross section for inclusive jet
  production in polarized proton collisions at sqrt(s) = 200 GeV

abstract:
  We report a measurement of the longitudinal double-spin asymmetry A_LL and
the differential cross section for inclusive midrapidity jet production in
polarized proton collisions at sqrt(s)=200 GeV. The cross section data cover
transverse momenta 5 < pT < 50 GeV/c and agree with next-to-leading order
perturbative QCD evaluations. The A_LL data cover 5 < pT < 17 GeV/c and
disfavor at 98% C.L. maximal positive gluon polarization in the polarized
nucleon.


title: Observation of a new DsJ meson in B+ -> D0-bar D0 K+ decays

abstract:
  We report the observation of a new DsJ meson produced in B+ -> D0-bar DsJ ->
D0-bar D0 K+. This state has a mass of M = 2715 +-11(stat) +11-14(syst)
MeV/c^2, a width Gamma = 115 +-20(stat) +36-32(syst) MeV/c^2 and a spin-parity
1-. The results are based on an analysis of 449 million BB-bar events collected
at the Upsilon(4S) resonance in the Belle detector at the KEKB asymmetric
energy e+e- collider.


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

abstract:
  We summarize the top-quark mass measurements from the CDF and DO experiments
at Fermilab. We combine published Run-I (1992-1996) measurements with the most
recent preliminary Run-II (2001-present) measurements using up to 1 fb-1 of
data. Taking correlated uncertainties properly into account the resulting
preliminary world average mass of the top quark is Mtop = 171.4 +/- 1.2 (stat)
+/- 1.8 (syst) GeV/c2, which corresponds to a total uncertainty of 2.1 GeV/c2.
The top-quark mass is now known with a precision of 1.2%.

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

abstract:
  We report improved measurements of B decays with an eta meson in the final
state using 492 fb^{-1} of data collected by the Belle detector at the KEKB e^+
e^- collider. We observe the decays B^{+-}-> eta pi^{+-} and B^{+-}-> eta
K^{+-}; the measured branching fractions are Br(B^{+-}-> eta pi^{+-}) = (4.2+-
0.4(stat)+- 0.2(sys))x10^{-6} and Br(B^{+-}-> eta K^{+-}) =
(1.9+-0.3(stat)^{+0.2}_{-0.1}(sys))x10^{-6}. The corresponding CP-violating
asymmetries are measured to be -0.23+- 0.09(stat) +-0.02(sys) for eta pi^{+-}
and -0.39+-0.16(stat)+-0.03(sys) for eta K^{+-}. We also search for B^0-> eta
K^0 decays and set an upper limit of 1.9x10^{-6} at the 90% confidence level.


title: Measurement of charmless $B$ Decays to $\eta K^*$ and $\eta \rho$

abstract:
  We report branching fractions and CP asymmetries for $B \to \eta K^*$ and $B
\to \eta \rho$ decays. These results are obtained from a $414 {\rm fb}^{-1}$
data sample collected at the $\Upsilon(4S)$ resonance, with the Belle detector
at the KEKB asymmetric energy $e^+ e^-$ collider. The branching fractions, in
parts per million, of $\eta K^{*0}$, $\eta K^{*+}$, $\eta \rho^0$, and $\eta
\rho^+$ are $15.9\pm 1.2 \pm 0.9$, $19.7^{+2.0}_{-1.9} \pm 1.4$,
$0.84^{+0.56}_{-0.51} \pm 0.18$, and $4.1^{+1.4}_{-1.3} \pm 0.34$,
respectively. We find no evidence for CP asymmetries in these modes.


title:
Observation of Direct CP-Violation in B0 --> pi+pi- Decays and
  Model-Independent Constraints on phi2

abstract:
  We present a new measurement of the time-dependent CP-violating parameters in
B0 -> pi+pi- decays using a data sample that contains 535M BBbar pairs
collected with the Belle detector at the KEKB asymmetric-energy e+e- collider
operating at the Upsilon(4S) resonance. We reconstruct one neutral B meson as a
pi+pi- CP eigenstate and identify the flavor of the accompanying B meson from
its decay products. We find 1464+-65 B0 --> pi+pi- events and perform an
unbinned maximum likelihood fit to the distribution of the proper-time
differences between the two B meson decays. The fit yields the CP-violating
parameters: Spipi = -0.61 +- 0.10(stat) +- 0.04(syst) and Apipi = +0.55 +-
0.08(stat) +- 0.05(syst). Large direct CP-violation is observed with a
significance greater than 5 standard deviations for any Spipi value. Using
isospin relations, we measure the Cabibbo-Kobayashi-Maskawa quark-mixing matrix
angle phi2 = (97 +- 11) degrees for the solution consistent with the standard
model and exclude a range of 11<phi2<79 degrees at the 95% confidence level.


title: Observation of B+ --> K0bar K+ and B0 --> K0 K0bar

abstract:
  We report observations of the b --> d penguin-dominated decays B+ --> K0bar
K+ and B0 --> K0 K0bar in approximately 350 million Upsilon(4S) --> BBbar
decays collected with the BaBar detector. We measure the branching fractions
B(B+ --> K0bar K+) = (1.61 +/- 0.44 +/- 0.09) * 10^-6 and B(B0 --> K0 K0bar) =
(1.08 +/- 0.28 +/- 0.11) * 10^-6, and the CP-violating charge asymmetry
A_{CP}(K0bar K+) = 0.10 +/- 0.26 +/- 0.03. Using a vertexing technique
previously employed in several analyses of all-neutral final states containing
kaons, we report the first measurement of time-dependent CP-violating
asymmetries in B0 --> K0 K0bar, obtaining S = -1.28 +0.80/-0.73 +0.11/-0.16 and
C = -0.40 +/- 0.41 +/- 0.06. We also report improved measurements of the
branching fraction B(B+ --> K0 pi+) = (23.9 +/- 1.1 +/- 1.0) * 10^-6 and
CP-violating charge asymmetry A_{CP}(K0 pi+) = -0.029 +/- 0.039 +/- 0.010.

  We report measurements and searches for resonant $B^{\pm} \to K^{\pm} h \to
K^{\pm} \gamma \gamma$ decays where $h$ is a

title:
Review of Recent and Future Needs in Hadronic Flavor Particle Production
  Measurements

abstract:
  Interactions of energetic particles on target nuclei producing secondary
particles will be reviewed. Current simulation codes rely upon poorly measured
results from the past. While current neutrino experiments, both atmospheric and
accelerator based, rely upon Kaon and pion production measurements which are
poorly known and dominate their errors. The goal for the current round of
experiments are to dramatically improve these measurements while improvments
beyond this are still needed. It is not only of interest to neutrino
experiments, but also for designing calorimeters for the the International
Linear Collider which must achieve unprecedented resolutions for reaching their
stated physics goals.


title:
Observation of Time-Dependent CP Violation in B0 -> eta' K0 Decays and
  Improved Measurements of CP Asymmetries in B0 -> phiK0, KsKsKs and B0 ->
  J/psi K0 Decays

abstract:
  We present improved measurements of CP-violation parameters in B0->phiK0,
eta'K0, KsKsKs decays based on a sample of 535x10^6 BBbar pairs collected at
the Y(4S) resonance with the Belle detector at the KEKB energy-asymmetric e+e-
collider. We obtain sin2phi_1^eff=+0.64+-0.10(stat)+-0.04(syst) for B0->eta'K0,
+0.50+-0.21(stat)+-0.06(syst) for B0->phiK0, and +0.30+-0.32(stat) +-0.08(syst)
for B0->KsKsKs decays. We have observed CP violation in the B0->eta'K0 decay
with a significance of 5.6 standard deviations. We also perform an improved
measurement of CP asymmetries in B0->J/psiK0 decays and obtain
sin2phi_1=+0.642+- 0.031(stat)+-0.017(syst).


title: The Double Chooz Experiment

abstract:
  There is broad consensus in the worldwide physics community as to the need
for a new reactor-neutrino experiment to measure or limit the neutrino mixing
angle $\theta_{13}$. The Double Chooz Experiment, planned for operation in the
years 2008-2011, will search for values of $\sin^2{2\theta_{13}}$ down to
$\approx$0.03. This will be the first new information on $\theta_{13}$ in over
a decade and will cover most of the remaining parameter space. A quick and
relatively inexpensive project is made possible by the existing neutrino
laboratory at the Chooz site.


title: The single production of the lightest E6 isosinglet quark at the LHC

abstract:
  We study the jet associated production of the new quarks predicted by the
$E_{6}$ GUT model at the LHC. Generator level considerations are made for
different mass values of the lightest of the new quarks to investigate its
discovery potential and the prospects for obtaining its mixing angle to the
Standard Model quarks. We find that after 100 fb$^{-1}$ of data taking, it is
possible to discover the new quark with a significance more than 5$\sigma$ up
to a mass of 1500 GeV. If no discovery is made, it is possible to constrain the
mass vs quark mixing angle plane.


title:
Inclusive D* Meson Cross Sections and D* Jet Correlations in
  Photoproduction at HERA

abstract:
  Differential photoproduction cross sections are measured for events
containing D* mesons. The data were taken with the H1 detector at the ep
collider HERA and correspond to an integrated luminosity of 51.1 pb-1. The
kinematic region covers small photon virtualities Q^2 < 0.01 GeV^2 and
photon-proton centre-of-mass energies of 171 < W_gammap < 256 GeV. The details
of the heavy quark production process are further investigated in events with
one or two jets in addition to the D* meson. Differential cross sections for D*
jet production are determined and the correlations between the D* meson and the
jet(s) are studied. The results are compared with perturbative QCD predictions
applying collinear- or kt -factorisation.


title: Experimental Constraints on the Spin and Parity of the Lambda_c(2880)

abstract:
  We report the results of several studies of the Lambda_c+pi+pi-X final state
in continuum e+e- annihilation data collected by the Belle detector. An
analysis of angular distributions in Lambda_c(2880)->Sigma_c(2455)pi decays
strongly favors a Lambda_c(2880) spin assignment of 5/2 over 3/2 or 1/2. We
find evidence for Lambda_c(2880)->Sigma_c(2520)pi decay and measure the ratio
of Lambda_c(2880) partial widths
Gamma[Sigma_c(2520)pi]/Gamma[Sigma_c(2455)pi]=0.225+-0.062+-0.025. This value
favors the Lambda_c(2880) spin-parity assignment of 5/2+ over 5/2-. We also
report the first observation of Lambda_c(2940)->Sigma_c(2455)pi decay and
measure Lambda_c(2880) and Lambda_c(2940) parameters. These studies are based
on a 553/fb data sample collected at or near the Upsilon(4S) resonance, at the
KEKB collider.


title:
Experimental discrimination between charge 2e/3 top quark and charge
  4e/3 exotic quark production scenarios

abstract:
  We present the first experimental discrimination between the 2e/3 and 4e/3
top quark electric charge scenarios, using top quark pairs (ttbar) produced in
ppbar collisions at sqrt{s}=1.96 TeV by the Fermilab Tevatron collider. We use
370 pb-1 of data collected by the D0 experiment and select events with at least
one high transverse momentum electron or muon, high transverse energy
imbalance, and four or more jets. We discriminate between b- and bbar-quark
jets by using the charge and momenta of tracks within the jet cones. The data
is consistent with the expected electric charge, |q|=2e/3. We exclude, at the
92% C.L., that the sample is solely due to the production of exotic quark pairs
QQbar with |q|=4e/3. We place an upper limit on the fraction of QQbar pairs fq
< 0.80 at the 90% C.L.


title: MuLan: Towards a 1ppm muon lifetime measurement

abstract:
  The MuLan experiment will measure the lifetime of the positive muon to 1ppm.
Within the Standard Model framework, this will permit a determination of the
Fermi Constant to 0.5ppm. I present an update on our progress and achievements
to date.


title:
Measurement of the mass of the $\tau$-lepton and an upper limit on the
  mass difference between $\tau^+$ and $\tau^-$

abstract:
  The mass of the $\tau$ lepton has been measured in the decay mode $\tau \to
3\pi \nu_\tau$ using a pseudomass technique. The result obtained from $414
\mathrm{fb}^{-1}$ of data collected with the Belle detector is $M_\tau =
(1776.61\pm 0.13 {(stat.)} \pm 0.35 {(sys.)})$ MeV/$c^2$. The upper limit on
the relative mass difference between positive and negative $\tau$ leptons is
$|M_{\tau^+}-M_{\tau^-}|/M_{\tau} < 2.8 \times 10^{-4}$ at 90% confidence
level.


title: Search for B0 -> K*0 nu nubar Using One Fully Reconstructed B Meson

abstract:
  We present a search for the rare decay B0 -> K*0 nu nubar, using a data
sample of 492 fb^-1 collected with the Belle detector at the KEKB e+e-
collider. Signal candidates are required to have an accompanying B meson fully
reconstructed in one of the hadronic modes and signal-side particles consistent
with a single K*0 meson. No significant signal is observed in the data sample
and we set a 90% confidence level upper limit of 3.4 x 10^-4 on the branching
fraction.


title:
Inclusive-jet and dijet cross sections in deep inelastic scattering at
  HERA

abstract:
  Inclusive-jet and dijet differential cross sections have been measured in
neutral current deep inelastic ep scattering for exchanged boson virtualities
Q2 > 125 GeV2 with the ZEUS detector at HERA using an integrated luminosity of
82 pb-1. Jets were identified in the Breit frame using the kt cluster
algorithm. Jet cross sections are presented as functions of several kinematic
and jet variables. The results are also presented in different regions of Q2.
Next-to-leading-order QCD calculations describe the measurements well. Regions
of phase space where the theoretical uncertainties are small have been
identified. Measurements in these regions have the potential to constrain the
gluon density in the proton when used as inputs to global fits of the proton
parton distribution functions.


title: Observation of B Decays to Two Kaons

abstract:
  Using 449 million BBbar pairs collected with the Belle detector at the KEKB
asymmetric-energy e^+e^- collider, we observe clear signals for B^+-> \bar{K}^0
K^+ and B^0-> \bar{K}^0 K^0 decays with 5.3 sigma and 6.0 sigma significance,
respectively. We measure the branching fractions Br(B^+-> \bar{K}^0 K^+ =
(1.22^{+0.32+0.13}_{-0.28-0.16})x10^{-6} and Br(B^0-> \bar{K}^0 K^0) =
(0.87^{+0.25}_{-0.20} +- 0.09)x10^{-6}, and partial-rate asymmetries
A_{CP}(B^+-> \bar{K}^0 K^+) = 0.13^{+0.23}_{-0.24}+- 0.02 and A_{CP}(B^0->
\bar{K}^0 K^0) = -0.58^{+0.73}_{-0.66}+- 0.04. From a simultaneous fit we also
obtain Br(B^+-> K^0\pi^+)= (22.8^{+0.8}_{-0.7} +- 1.3)x 10^{-6} and
A_{CP}(B^+-> K^0 \pi^+) = 0.03 +- 0.03 +- 0.01. The first and second error in
the branching fractions and the partial-rate asymmetries are statistical and
systematic, respectively. No signal is observed for B^0-> K^+ K^- decays, and
for this branching fraction we set an upper limit of 4.1x10^{-7} at the 90%
confidence level.


title: Inclusive Hadron Production in p+p Collisions at STAR

abstract:
  The STAR experiment at RHIC has measured a variety of inclusive hadron cross
sections in $p+p$ collisions at Sqrt(s) = 200 GeV. Measurements of the
differential cross section for inclusive charged pion production at mid
rapidity and for inclusive neutral pion production at forward rapidity (3.0 <
eta < 4.2) as well as the first preliminary result from STAR for the
differential cross section for inclusive neutral pion production near mid
rapidity are presented. These cross sections are compared to next-to-leading
order perturbative QCD calculations and can provide constraints on the pion
fragmentation functions. Good agreement between data and pQCD has been found
for all three cross sections.


title:
Measurement of the CP Asymmetry and Branching Fraction of B^0 to rho^0
  K^0

abstract:
  We present a measurement of the branching fraction and time-dependent CP
asymmetry of B^0 to rho^0 K^0. The results are obtained from a data sample of
227 10^6 Y4S to BB_ decays collected with the BaBar detector at the PEP2
asymmetric-energy B Factory at SLAC. From a time-dependent maximum likelihood
fit yielding 111+/-19 signal events we find B(B^0 to rho^0
K^0)=(4.9+/-0.8+/-0.9) 10^-6, where the first error is statistical and the
second systematic. We report the measurement of the CP parameters
S=0.20+/-0.52+/-0.24 and C=0.64+/-0.41+/-0.20.


title:
Measurement of the ratios of the Z/G* + >= n jet production cross
  sections to the total inclusive Z/G* cross section in ppbar collisions at
  sqrt(s) = 1.96 TeV

abstract:
  We present a study of events with Z bosons and jets produced at the Fermilab
Tevatron Collider in ppbar collisions at a center of mass energy of 1.96 TeV.
The data sample consists of nearly 14,000 Z/G* -> e+e- candidates corresponding
to the integrated luminosity of 0.4 fb-1 collected using the D0 detector.
Ratios of the Z/G* + >= n jet cross sections to the total inclusive Z/G* cross
section have been measured for n = 1 to 4 jet events. Our measurements are
found to be in good agreement with a next-to-leading order QCD calculation and
with a tree-level QCD prediction with parton shower simulation and
hadronization.


title:
Measurement of azimuthal asymmetries in neutral current deep inelastic
  scattering at HERA

abstract:
  The distribution of the azimuthal angle of charged and neutral hadrons
relative to the lepton plane has been studied for neutral current deep
inelastic $ep$ scattering using an integrated luminosity of 45 pb-1 taken with
the ZEUS detector at HERA. The measurements were made in the hadronic
centre-of-mass system. The analysis exploits the energy-flow method, which
allows the measurement to be made over a larger range of pseudorapidity
compared to previous results. The dependence of the moments of the azimuthal
distributions on the pseudorapidity and minimum transverse energy of the
final-state hadrons are presented. Although the predictions from
next-to-leading-order QCD describe the data better than do the Monte Carlo
models incorporating leading-logarithm parton showers, they still fail to
describe the magnitude of the asymmetries. This suggests that higher-order
calculations may be necessary to describe these data.


title: Double beta decay experiments: past and present achievements

abstract:
  A brief history of double beta decay experiments is presented. The best
currently running experiments (NEMO-3 and CUORICINO) and their latest results
are described. The best measurements and limits for the $2\nu\beta\beta$,
$0\nu\beta\beta$ and $0\nu\chi^{0}\beta\beta$ are summarized.


title: Observation of an Excited Charm Baryon OmegaC* Decaying to OmegaC0 Gamma

abstract:
  We report the first observation of an excited singly-charm baryon OmegaC*
(css) in the radiative decay OmegaC0 Gamma, where the OmegaC0 baryon is
reconstructed in the decays to the final states Omega-pi+, Omega-pi+pi0,
Omega-pi+pi-pi+, and Cascade-K-pi+pi+. This analysis is performed using a
dataset of 230.7 fb$-1} collected by the BABAR detector at the PEP-II
asymmetric-energy B Factory at the Stanford Linear Accelerator Center. The mass
difference between the OmegaC* and the OmegaC0 baryons is measured to be 70.8
+/- 1.0 (stat) +/- 1.1 (syst) MeV/c2. We also measure the ratio of inclusive
production cross sections of OmegaC* and OmegaC0 in e+e- annihilation.


title: Ratio of Branching Fractions for $\chi_{cJ} \to \gamma J/\psi$

abstract:
  One important quarkonia result from the Tevatron experiments is the ratio of
direct inclusive production of \chi_{c1} to \chi_{c2}, which is most readily
measured using \chi_{cJ}\to\gamma J/\psi decays. This note uses CLEO
publications to obtain a ratio of these radiative branching fractions, {\cal
B}(\chi_{c1}\to\gamma J/\psi)/{\cal B}(\chi_{c2}\to\gamma J/\psi) = 1.91 \pm
0.10, using cancelation in systematic uncertainties not available in the
Particle Data Group listings.


title: Search for Neutral Q-balls in Super-Kamiokande II

abstract:
  A search for Q-balls induced groups of successive contained events has been
carried out in Super-Kamiokande II with 541.7 days of live time.
  Neutral Q-balls would emit pions when colliding with nuclei, generating a
signal of successive contained pion events along a track. No candidate for
successive contained event groups has been found in Super-Kamiokande II, so
upper limits on the possible flux of such Q-balls have been obtained.


title:
Improved KL->pi e nu Form Factor and Phase Space Integral with Reduced
  Model Uncertainty

abstract:
  Using the published KTeV sample of 2 million KL-> pi e nu decays and a new
form factor expansion with a rigorous bound on higher order terms, we present a
new determination of the KL->pi e nu form factor and phase space integral.
Compared to the previous KTeV result, the uncertainty in the new form factor
expansion is negligible and results in an overall uncertainty in the phase
space integral (IKe) that is a factor of two smaller: IKe = 0.15392 +- 0.00048
\.


title: Event Rates for Off Axis NuMI Experiments

abstract:
  Neutrino interaction rates for experiments placed off axis in the NuMI beam
are calculated. Primary proton beam energy is 120 GeV and four locations at 810
km from target and 6, 12, 30 and 40 km off axis are considered. This report is
part of the Joint FNAL/BNL Future Long Baseline Neutrino Oscillation Experiment
Study.


title: Search for gluinos with ATLAS at LHC

abstract:
  Prospects for ATLAS observation of a SUSY-like signal from two gluinos are
investigated within a certain region of the mSUGRA parameter space, where the
cross section of the two gluinos production via gluon-gluon fusion is estimated
at a rather high level of 13 pb. The event selection trigger uses a very clear
signature of the process (4 jets + 4 muons + up to 4 secondary vertices
topology) when final decay products of each gluino are b-anti-b and
muon-anti-muon pairs and the lightest SUSY particle, the neutralino. Rather
high transverse missing energy carried away by two neutralinos is an essential
signature of the event and also allows the relevant Standard Model background
to be reduced significantly. The generation and reconstruction processes are
performed by means of the ATLAS common software framework ATHENA.


title: LVD highlights

abstract:
  The Large Volume Detector (LVD) in the INFN Gran Sasso National Laboratory,
Italy, is a $\nu$ observatory mainly designed to study low energy neutrinos
from the gravitational collapse of galactic objects. The experiment has been
monitoring the Galaxy since June 1992, under increasing larger configurations:
in January 2001 it has reached its final active mass M=1 kt. LVD is one of the
largest liquid scintillator apparatus in the world for the detection of stellar
collapses and, besides SNO, SuperKamiokande and Amanda, it is a charter member
of the SNEWS network, that has become fully operational since July 1st, 2005.
No gravitational core-collapse has been detected by LVD during 14 years of data
acquisition; this allows to put an upper limit of 0.18 events y$^{-1}$ in our
galaxy at the 90% C.L. The LVD tracking system allows the detection and the
recontruction of the cosmic muon tracks in a large fraction of the whole solid
angle, in particular also horizontal tracks can be reconstructed. The results
of the muon depth--intensity relation and of the flux of neutrino--induced
muons are presented. Moreover, during 2006, the CNGS beam will start its
operation: the performances of LVD as a beam monitor are described.


title:
Search for V+A current in top quark decay in ppbar collisions at
  sqrt{s}=1.96 TeV

abstract:
  We report an upper limit on the fraction of V+A current, $f_{V+A}$, in top
quark decays, using approximately 700 pb$^{-1}$ of $p\bar{p}$ collisions at
$\sqrt{s}$=1.96 TeV acquired by the upgraded Collider Detector at Fermilab. For
the decay $t \to Wb \to \ell \nu b$ (where $\ell=e$ or $\mu$), the invariant
mass of the charged lepton and the bottom quark jet is sensitive to the
polarization of the $W$ boson. We determine $f_{V+A} = -0.06 \pm 0.25$ given a
top quark mass of 175 GeV/$c^{2}$. We set an upper limit on $f_{V+A}$ of 0.29
at the 95% confidence level, which represents an improvement by a factor of two
on the previous best direct limit.


title: Charmed Hadrons from Fragmentation and B Decays

abstract:
  The fragmentation functions of $D^0$, $D^{\pm}$, $D_s^{\pm}$, $D^{*o}$,
$D^{*\pm}$ and $\Lambda_c^{\pm}$ at $\sqrt{s}$$\simeq$10.6 GeV are measured
with a data set of 102.7 fb$^{-1}$. Fragmentation model parametrizations
(Peterson, Kartvelishvili, Collins-Spiller, Lund, and Bowler models) are
compared to the data. The data at high $x$$\simeq$1 indicate a contribution of
non-perturbative QCD processes.


title: Diffractive DIS Cross Sections and Parton Distributions

abstract:
  Highlights are presented mainly from two recent measurements of the
diffractive Deep Inelastic Scattering cross section at HERA. In the first, the
process $ep\to eXp$ is studied by tagging the leading final state proton. In
the second, events of this type are selected by requiring a large rapidity gap
devoid of hadronic activity in the proton direction. The two measurements are
compared in detail and the kinematic dependences are interpreted within the
framework of a factorisable diffractive exchange. Diffractive parton
distributions are determined from a next-to-leading order QCD analysis of the
large rapidity gap data, which can be applied to the prediction of diffractive
processes, also at the TEVATRON and the LHC.


title:
Search of Axions from a Nuclear Power Reactor with a High-Purity
  Germanium Detector

abstract:
  A search of axions produced in nuclear transitions was performed at the
Kuo-Sheng Nuclear Power Station with a high-purity germanium detector of mass
1.06 kg at a distance of 28 m from the 2.9 GW reactor core. The expected
experimental signatures were mono-energetic lines produced by their Primakoff
or Compton conversions at the detector. Based on 459.0/96.3 days of Reactor
ON/OFF data, no evidence of axion emissions were observed and constraints on
the couplings $\gagg$ and $\gaee$ versus axion mass $m_a$ within the framework
of invisible axion models were placed. The KSVZ and DFSZ models can be excluded
for 10^4 eV < m_a < 10^6 ~eV. Model-independent constraints on \gagg \gv1 < 7.7
X 10^{-9} GeV^{-2} for m_{a} < 10^5 eV and \gaee \gv1 < 1.3 X 10^{-10} for
m_{a} < 10^6 eV at 90% confidence level were derived. This experimental
approach provides a unique probe for axion mass at the keV--MeV range not
accessible to the other techniques.


title: Finding The Charm In 800 GeV/c p-Cu and p-Be Single Muon Spectra

abstract:
  Fermilab Experiment 866 took single muon data from 800 GeV/c (sqrt{s}=38.8
GeV) p-Cu and p-Be interactions in an attempt to extract the inclusive nuclear
open charm/anti-charm differential cross sections as a function of transverse
momentum. The muons were decay products from semi-leptonic decays of open charm
mesons as well as decays from lighter non-charmed mesons (pions and kaons).
Data were taken simultaneously from two interaction regions; one of two thin
nuclear targets and a copper beam dump 92 inches downstream. The open decay
length for hadrons produced in the targets increased the contribution to the
muon spectrum from light hadron decays, relative to those from the dump.
Production cross sections for light hadrons from previous experiments were used
in conjunction with parameterized open charm cross sections to produce total
Monte Carlo single muon spectra that were subsequently fit to the data.
  The sensitivity of this measurement covered an open charm hadron transverse
momentum range of approximately 2 to 7 GeV/c, center-of-mass rapidity, y,
between 0 and 2, and Feynman-x between 0.2 and 0.8. Extrapolation of the cross
sections to small transverse momentum shows good agreement with previous
experiments. The power alpha of the nuclear dependency A^{alpha(p_T)} was
calculated as a function of transverse momentum. The result indicates that
alpha is transverse-momentum dependent, albeit within large errors.


title: B0 -> pi+ pi- pi0 time-dependent Dalitz analysis from Belle

abstract:
  We present the results of a time-dependent Dalitz plot analysis of B0 -> pi+
pi- pi0 decays based on a 414fb^-1 data sample that contains 449MBB pairs
collected on the Upsilon(4S) resonance with the Belle detector at the KEKB
asymmetric energy e+e- collider. The direct CP violating parameters of B0 ->
rho+-pi-+ decay mode are measured to be A_rhopi^+- = +0.22 +- 0.08(stat.) +-
0.05(syst.) and A_rhopi^-+ = +0.08 +- 0.17(stat.) +- 0.12(syst.). We also
measure the CP violating parameters of the decay mode B0 -> rho0pi0 as
A_rho0pi0 = -0.45 +- 0.35(stat.) +- 0.32(syst.) and S_rho0pi0 = +0.15 +-
0.57(stat.) +- 0.43(syst.). Combining our analysis with information on charged
B decay modes, we perform a full Dalitz and isospin analysis and obtain a
constraint on the CKM angle phi_2, phi_2 = (83^+12_-23)^\circ. A large
CKM-disfavored region (phi_2<8^\circ and 129^\circ <phi_2) also remains at
68.3% confidence level.


title:
Inclusive Lambda_c Production in e^+e^- Annihilations at sqrt{s}=10.54
  GeV and in Upsilon(4S) Decays

abstract:
  We present measurements of the total production rates and momentum
distributions of the charmed baryon $\Lambda_c^+$ in $e^+e^- \to$ hadrons at a
center-of-mass energy of 10.54 GeV and in $\Upsilon(4S)$ decays. In hadronic
events at 10.54 GeV, charmed hadrons are almost exclusively leading particles
in $e^+e^- \to c\bar{c}$ events, allowing direct studies of $c$-quark
fragmentation. We measure a momentum distribution for $\Lambda_c^+$ baryons
that differs significantly from those measured previously for charmed mesons.
Comparing with a number of models, we find none that can describe the
distribution completely. We measure an average scaled momentum of $\left< x_p
\right> = 0.574\pm$0.009 and a total rate of $N_{\Lambda c}^{q\bar{q}} =
0.057\pm$0.002(exp.)$\pm$0.015(BF) $\Lambda_c^+$ per hadronic event, where the
experimental error is much smaller than that due to the branching fraction into
the reconstructed decay mode, $pK^-\pi^+$. In $\Upsilon (4S)$ decays we measure
a total rate of $N_{\Lambda c}^{\Upsilon} = 0.091\pm$0.006(exp.)$\pm$0.024(BF)
per $\Upsilon(4S)$ decay, and find a much softer momentum distribution than
expected from B decays into a $\Lambda_c^+$ plus an antinucleon and one to
three pions.


title:
Measurement of Angular Distributions of Drell-Yan Dimuons in p + d
  Interaction at 800 GeV/c

abstract:
  We report a measurement of the angular distributions of Drell-Yan dimuons
produced using an 800 GeV/c proton beam on a deuterium target. The muon angular
distributions in polar angle $\theta$ and azimuthal angle $\phi$ have been
measured over the kinematic range $4.5 < m_{\mu \mu} < 15$ GeV/c$^2$, $0 < p_T
< 4 $ GeV/c, and $0 < x_F < 0.8$. No significant cos$2\phi$ dependence is found
in these proton-induced Drell-Yan data, in contrast to the situation for
pion-induced Drell-Yan. The data are compared with expectations from models
which attribute the cos$2\phi$ distribution to a QCD vacuum effect or to the
presence of the transverse-momentum-dependent Boer-Mulders structure function
$h_1^\perp$. Constraints on the magnitude of the sea-quark $h_1^\perp$
structure functions are obtained.


title:
Measurements of time-dependent CP violation in $B^0 \to \omega K_S^0$,
  $f_0(980) K_S^0$, $K_S^0 \pi^0$ and $K^+ K^- K_S^0$ decays

abstract:
  We present measurements of time-dependent CP asymmetries in $B^0 \to \omega
K_S^0$, $f_0 (980) K_S^0$, $K_S^0 \pi^0$ and $K^+ K^- K_S^0$ based on a sample
of 535 $\times 10^6$ $B\bar{B}$ pairs collected at the $\Upsilon(4S)$ resonance
with the Belle detector at the KEKB energy-asymmetric $e^+ e^-$ collider. One
neutral $B$ meson is fully reconstructed in one of the specified decay
channels, and the flavor of the accompanying $B$ meson is identified from its
decay products. CP-violation parameters for each of the decay modes are
obtained from the asymmetries in the distributions of the proper-time intervals
between the two B decays.


title: Measurement of the eta->pi+pi-e+e- decay branching ratio

abstract:
  The reaction pd->3He eta at threshold was used to provide a clean source of
eta mesons for decay studies with the WASA detector at CELSIUS. The branching
ratio of the decay eta->pi+pi-e+e- is measured to be (4.3+/-1.3+/-0.4)x10^-4.


title:
Branching Fraction for the Doubly-Cabibbo-Suppressed Decay D^+ --> 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) = (2.28 +- 0.36 +- 0.15 +- 0.08) 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 branching fraction.


title:
Dalitz plot analysis of e+ e- --> pi0 pi0 gamma events at SQRT(s) ~
  M(phi) with the KLOE detector

abstract:
  We have studied the Dalitz plot of the e+ e- --> pi0 pi0 gamma events
collected at SQRT(s) ~ M(phi) with the KLOE detector. In the dipion invariant
mass (Mpp) region below 700 MeV, the process under study is dominated by the
non-resonant process e+ e- --> omega pi0 with omega --> pi0 gamma whereas, for
higher Mpp values, the radiative phi decay to the f0(980) is the dominant
mechanism. Different theoretical models are used to fit the Dalitz plot, taking
also into account a possible contribution of the sigma(600). For each model, we
extract the f0(980) mass and its coupling to pipi, KKbar and to the phi.


title:
Measurement of high-p_T Single Electrons from Heavy-Flavor Decays in p+p
  Collisions at sqrt(s) = 200 GeV

abstract:
  The momentum distribution of electrons from decays of heavy flavor (charm and
beauty) for midrapidity |y| < 0.35 in p+p collisions at sqrt(s) = 200 GeV has
been measured by the PHENIX experiment at the Relativistic Heavy Ion Collider
(RHIC) over the transverse momentum range 0.3 < p_T < 9 GeV/c. Two independent
methods have been used to determine the heavy flavor yields, and the results
are in good agreement with each other. A fixed-order-plus-next-to-leading-log
pQCD calculation agrees with the data within the theoretical and experimental
uncertainties, with the data/theory ratio of 1.72 +/- 0.02^stat +/- 0.19^sys
for 0.3 < p_T < 9 GeV/c. The total charm production cross section at this
energy has also been deduced to be sigma_(c c^bar) = 567 +/- 57^stat +/-
224^sys micro barns.


title: Borexino

abstract:
  Borexino is a massive calorimetric liquid scintillation detector whose
installation has been completed in the underground Gran Sasso Laboratory. The
focus of the experiment is on the direct and real time measurement of the flux
of neutrinos produced in the $^{7}Be$ electron capture reaction in the Sun.
Furthermore, recent studies about the reduction of the $^{11}C$ background
through suitable rejection techniques demonstrated the possibility to open an
interesting additional observation window in the energy region of the pep and
CNO solar neutrinos. Beyond the solar neutrino program, the detector will be
also a powerful observatory for antineutrinos from Supernovae, as well as for
geoneutrinos, profiting from a very low background from nuclear reactors.


title: W and Z Production at the Tevatron

abstract:
  In this paper, recent experimental results on W and Z boson production at the
Tevatron are described. These results not only provide tests of the standard
model, but are also sensitive to proton parton distribution functions.


title:
Search for Lepton Flavor Violating tau^- Decays into l^-eta, l^-eta' and
  l^-pi^0

abstract:
  We have searched for lepton flavor violating $\tau$ decays with a
pseudoscalar meson ($\eta$, $\eta'$ and $\pi^0$) using a data sample of 401
fb$^{-1}$ collected with the Belle detector at the KEKB asymmetric-energy
$e^+e^-$ collider. No evidence for these decays is found and we set the
following upper limits on the branching fractions: ${\cal{B}}(\tau^-\to
e^-\eta) < 9.2\times 10^{-8}$, ${\cal{B}}(\tau^-\to \mu^-\eta) < 6.5\times
10^{-8}$, ${\cal{B}}(\tau^-\to e^-\eta') < 1.6\times 10^{-7}$,
${\cal{B}}(\tau^-\to \mu^-\eta') < 1.3\times 10^{-7}$ ${\cal{B}}(\tau^-\to
e^-\pi^0) < 8.0\times 10^{-8}$ and ${\cal{B}}(\tau^-\to \mu^-\pi^0) < 1.2\times
10^{-7}$ at the 90% confidence level, respectively. These results improve the
previously published limits by factors from 2.3 to 6.4.


title:
Measurement of the CP-violation parameter of B^0 mixing and decay with
  pp(bar) -> mu mu X data

abstract:
  We measure the dimuon charge asymmetry A in pp(bar) collisions at a center of
mass energy sqrt{s} = 1960 GeV. The data was recorded with the D0 detector and
corresponds to an integrated luminosity of approximately 1.0 fb-1. Assuming
that the asymmetry A is due to asymmetric B^0 <-> B(bar)^0 mixing and decay, we
extract the CP-violation parameter of B^0 mixing and decay:
  Re(epsilon_B^0)(1 + |epsilon_B^0|^2) = A_B^0/4 = -0.0023 +/- 0.0011 (stat)
+/- 0.0008 (syst).
  A_B^0 is the dimuon charge asymmetry from decays of B^0 B(bar)^0 pairs. The
general case, with CP violation in both B^0 and B_s^0 systems, is also
considered. Finally we obtain the forward-backward asymmetry that quantifies
the tendency of mu+ to go in the proton direction and mu- to go in the
anti-proton direction. The results are consistent with the standard model and
constrain new physics.


title:
Improved measurements of branching fractions for B -> K pi and B -> pi
  pi decays

abstract:
  We report improved measurements of branching fractions for B -> K pi and B ->
pi pi decays based on a data sample of 449 million B Bbar pairs collected at
the Upsilon(4S) resonance with the Belle detector at the KEKB e^+e^- collider.
We also calculate the ratios of partial widths for the decays B -> K pi and pi
pi, namely R_c = 1.08 +- 0.06 +- 0.08 and R_n = 1.08 +-0.08 +0.09-0.08, where
the first and second errors are statistical and systematical, respectively.
These ratios are sensitive to enhanced electroweak penguin contributions from
new physics; the new measurements are, however, consistent with Standard Model
expectations.


title: Observation of $B \to \phi \phi K$ Decays

abstract:
  We report the observation of the decay $B^{\pm} \to \phi \phi K^{\pm}$ and
find evidence for $B^{0} \to \phi \phi K^{0}$. These results are based on a 414
fb$^{-1}$ data sample that contains $449 \times 10^6$ $B\bar{B}$ pairs,
collected with the Belle detector at the KEKB asymmetric-energy $e^+e^-$ (3.5
on 8 GeV) collider operating at the $\Upsilon(4S)$ resonance. This is the first
observation of a $b \to s \bar{s} s \bar{s} s$ transition. The branching
fractions for these decay modes are measured to be $\mathcal{B}(B^{\pm} \to
\phi \phi K^{\pm}) = (3.2^{+0.6}_{-0.5} \pm 0.3) \times 10^{-6}$ and
$\mathcal{B}(B^{0} \to \phi \phi K^{0}) = (2.3^{+1.0}_{-0.7} \pm 0.2) \times
10^{-6}$ for $\phi \phi$ invariant mass below 2.85 GeV/$c^2$. The corresponding
partial rate asymmetry for the charged $B$ mode is measured to be
$\mathcal{A}_{CP}(B^\pm\to \phi \phi K^\pm) = 0.01^{+ 0.19}_{-0.16}\pm 0.02$.
Results for other related charmonium decay modes are also reported. We also
search for CP asymmetry using the $\phi\phi$ candidates within the $\eta_c$
mass region. The value obtained is $\mathcal{A}_{CP}(B^\pm \to \phi \phi K^\pm,
M_{\phi \phi} \approx M_{\eta_c})= 0.15^{+0.16}_{-0.17} \pm 0.02$, which is
consistent with no asymmetry.


title: Searches for Squarks and Gluinos at CDF and D0 Detectors

abstract:
  This contribution reports on preliminary measurements on searches for squarks
and gluinos at CDF and D\O detectors in $p\bar{p}$ collisions at
$\sqrt{s}=1.96$ TeV. The analyses are performed using event topologies with
multiple jets and large missing energy in the final state. The mSUGRA scenario
and R-parity conservation is assumed. No excess with respect to the Standard
Model predictions is observed and new limits on the gluino and squark masses
are extracted.


title: First Observation of the Decay tau^- -> phi K^- nu_tau

abstract:
  We present the first observation of tau lepton decays to hadronic final
states with a phi-meson. This analysis is based on 401 fb^-1 of data
accumulated at the Belle experiment. The branching fraction obtained is B(tau-
-> phi K- nu) = (4.05 +- 0.25 +- 0.26) x 10^-5.


title: Low-x QCD with CMS at the LHC

abstract:
  The physics of gluon saturation and non-linear evolution at small values of
parton momentum fraction x in the proton and nucleus is discussed in the
context of experimental results at HERA and RHIC. The rich physics potential of
low-x QCD studies at the LHC is discussed and some measurements in pp, pA and
AA collisions accessible with the Compact Muon Solenoid (CMS) experiment are
presented.


title: Review of alpha_s Measurements

abstract:
  We present a review of measurements of alpha_S. The individual measurements
are discussed and intermediate averages for classes of related measurements are
found. The final average is built using the intermediate values. Correlations
are treated consistently. The ICHEP 2006 world average is alpha_S(M_Z) = 0.1175
+/- 0.0011 dominated by the recent result from lattice QCD.


title:
Measurement of the Lambda_b Lifetime in Lambda_b --> J/psi Lambda0 in
  p-pbar Collisions at sqrt(s)=1.96 TeV

abstract:
  We report a measurement of the Lambda_b lifetime in the exclusive decay
Lambda_b --> J/psi Lambda0 in p-pbar collisions at sqrt(s) = 1.96 TeV using an
integrated luminosity of 1.0 fb^{-1} of data collected by the CDF II detector
at the Fermilab Tevatron. Using fully reconstructed decays, we measure
tau(Lambda_b) = 1.593 ^{+0.083}_{-0.078} (stat.) +- 0.033 (syst.) ps. This is
the single most precise measurement of tau(Lambda_b) and is 3.2 sigma higher
than the current world average.


title:
Improved measurements of branching fractions and CP partial rate
  asymmetries for $B\to\omega K$ and $B\to\omega\pi$

abstract:
  We report improved measurements of $B$ to pseudoscalar-vector decays
containing an $\omega$ meson in the final states. Our results are obtained from
a data sample that contains $388\times 10^{6}$ $B\bar{B}$ pairs accumulated at
the $\Upsilon(4S)$ resonance, with the Belle detector at the KEKB
asymmetric-energy $e^+ e^-$ collider. We measure the following branching
fractions: ${\mathcal B}(B^{+} \to \omega K^{+}) = [8.1\pm0.6({\rm
stat.})\pm{0.6}({\rm syst.})]\times 10^{-6}$, ${\mathcal B}(B^{+} \to \omega
\pi^{+}) = [6.9\pm{0.6}({\rm stat.})\pm{0.5}({\rm syst.})]\times 10^{-6}$, and
${\mathcal B}(B^{0} \to \omega K^{0}) = [4.4^{+0.8}_{-0.7}({\rm
stat.})\pm{0.4}({\rm syst.})]\times 10^{-6}.$ The partial width ratio
$\frac{\Gamma (B^{+}\to \omega K^{+})}{\Gamma (B^{0}\to \omega K^{0})}$ =
$1.8\pm0.4({\rm stat.})\pm0.1({\rm sys.})$. We also set the 90% confidence
level upper limit ${\mathcal B}(B^{0} \to \omega \pi^{0}) < 2.0\times 10^{-6}.$
In addition, we obtain the partial rate asymmetries ${\mathcal A}_{CP} =
0.05^{+0.08}_{-0.07}(\rm {stat.}) \pm 0.01(\rm {syst.})$ for $B^{+} \to \omega
K^{+}$, and ${\mathcal A}_{CP} = -0.02 \pm 0.09(\rm {stat.}) \pm 0.01(\rm
{syst.})$ for $B^{+}\to \omega \pi^{+}$.


title: Improved measurement of $\psi (2S)$ decays into $\tau ^{+}\tau ^{-}$

abstract:
  Using 14M $\psi (2S)$ events collected at BESII, the branching fraction of
$\psi (2S)\to \tau ^{+}\tau ^{-}$ is measured to be $Br_{\tau \tau}=(3.10\pm
0.21\pm 0.38)\times 10^{-3}$, where the first error is statistical and the
second is systematic.


title:
The experimental feature on the data of the primary proton
  identification in stratospheric X-ray emulsion chambers at energies >10 TeV
  (RUNJOB experiment)

abstract:
  The RUNJOB balloon-born emulsion chamber experiments have been carried out
for investigating the composition and energy spectra of primary cosmic rays at
energies 10-1000 TeV/nucleon. On the data of the treatment of RUNJOB` X-ray
emulsion chambers exposed since 1995 to 1999 year about 50 % proton tracks were
identified. In remained half of the events from proton group the one charged
primary tracks were not found in the search area determined with high accuracy
by the triangulation method using the several background heavy tracks.
Considered methodical reasons in this paper could not explain this experimental
result. The one from the probable physical reasons that is the neutrons in
cosmic ray flux does not explain it too.


title: A Search for Sigma^0_5, N^0_5 and Theta^++ Pentaquark States

abstract:
  A high-resolution (sigma_instr. = 1.5 MeV) search for narrow states (Gamma <
10 MeV) with masses of M_x approx 1500-1850 MeV in ep -> e'K^+ X, e'K^- X and
e' pi^+ X electroproduction at small angles and low Q^2 was performed. These
states would be candidate partner states of the reported Theta^+(1540)
pentaquark. No statistically significant signal was observed in any of the
channels at 90% C.L. Upper limits on forward production were determined to be
between 0.7% and 4.2% of the Lambda(1520) production cross section, depending
on the channel and the assumed mass and width of the state.


title: Inclusive jet cross section measurement at D0

abstract:
  We present a new preliminary measurement of the inclusive jet cross section
in pp-bar collisions based on a integrated luminosity of about 0.8 fb-1. The
data were acquired using the D0 detector between 2002 and 2005. Jets are
reconstructed using an iterative cone algorithm with radius R_cone = 0.7. The
inclusive jet cross section is presented as a function of transverse jet
momentum and rapidity. Predictions from perturbative QCD in next-to-leading
order, plus threshold corrections in 2-loop accuracy describe the shape in the
transverse jet momentum.


title:
Observation of B+ -> Phi Phi K+ and evidence for B0 -> Phi Phi K0 below
  Eta_C threshold

abstract:
  We report measurements of the decays B+ -> Phi Phi K+ and B0 -> hi Phi K0
using a sample of 231 million BBbar pairs collected with the BABAR detector at
the PEP-II asymmetric-energy B Factory at the Stanford Linear Accelerator
Center. The branching fractions are measured to be Br(B+ -> Phi Phi K+) = (7.5
+/- 1.0 stat. +/- 0.7 syst.) * 10^-6 and Br(B0 -> Phi Phi K0) = (4.1 +1.7/-1.4
stat. +/- 0.4 syst.) * 10^-6 for a Phi Phi invariant mass below 2.85 GeV/c2.


title: Top Quark Mass Measurements

abstract:
  First observed in 1995, the top quark is one of a pair of third-generation
quarks in the Standard Model of particle physics. It has charge +2/3e and a
mass of 171.4 GeV, about 40 times heavier than its partner, the bottom quark.
The CDF and D0 collaborations have identified several hundred events containing
the decays of top-antitop pairs in the large dataset collected at the Tevatron
proton-antiproton collider over the last four years. They have used these
events to measure the top quark's mass to nearly 1% precision and to study
other top quark properties. The mass of the top quark is a fundamental
parameter of the Standard Model, and knowledge of its value with small
uncertainty allows us to predict properties of the as-yet-unobserved Higgs
boson. This paper presents the status of the measurements of the top quark
mass.


title: Hadronic final states and QCD studies at HERA

  Recent experimental results in charm and charmonium spectroscopy are
reviewed.


title:
Measurement of direct photon production in p + p collisions at sqrt(s) =
  200 GeV

abstract:
  Cross sections for mid-rapidity production of direct photons in p+p
collisions at the Relativistic Heavy Ion Collider (RHIC) are reported for 3 <
p_T < 16 GeV/c. Next-to-leading order (NLO) perturbative QCD (pQCD) describes
the data well for p_T > 5 GeV/c, where the uncertainties of the measurement and
theory are comparable. We also report on the effect of requiring the photons to
be isolated from parton jet energy. The observed fraction of isolated photons
is well described by pQCD for p_T > 7 GeV/c.


title:
Measurement of Single Muons at Forward Rapidity in p+p Collisions at
  sqrt(s) = 200 GeV and Implications for Charm Production

abstract:
  Muon production at forward rapidity (1.5 < |\eta| < 1.8) has been measured by
the PHENIX experiment over the transverse momentum range 1 < p_T \le 3 GeV/c in
sqrt(s) = 200 GeV p+p collisions at the Relativistic Heavy Ion Collider. After
statistically subtracting contributions from light hadron decays an excess
remains which is attributed to the semileptonic decays of hadrons carrying
heavy flavor, i.e. charm quarks or, at high p_T, bottom quarks. The resulting
muon spectrum from heavy flavor decays is compared to PYTHIA and a
next-to-leading order perturbative QCD calculation. PYTHIA is used to determine
the charm quark spectrum that would produce the observed muon excess. The
corresponding differential cross section for charm quark production at forward
rapidity is determined to be d\sigma_(c c^bar)/dy|_(y=1.6)=0.243 +/- 0.013
(stat.) +/- 0.105 (data syst.) ^(+0.049)_(-0.087) (PYTHIA syst.) mb.


title:
Measurement of the Absolute Branching Fractions B to Dpi, D*pi, D**pi
  with a Missing Mass Method

abstract:
  We present branching fraction measurements of charged and neutral B decays to
Dpi-, D*pi- and D**pi- with a missing mass method, based on a sample of 231
million Y(4S)-->BBar pairs collected by the BaBar detector at the PEP-II e+e-
collider. One of the B mesons is fully reconstructed and the other one decays
to a reconstructed charged pion and a companion charmed meson identified by its
recoil mass, inferred by kinematics. Here D** refers to the sum of all the
non-strange charm meson states with masses in the range 2.2-2.8 Gev/c2.


title: Measurement of Bd mixing using opposite-side flavor tagging

abstract:
  We report on a measurement of the $B^0_d$ mixing frequency and the
calibration of an opposite-side flavor tagger in the D{\O}experiment. Various
properties associated with the $b$ quark on the opposite side of the
reconstructed $B$ meson were combined using a likelihood-ratio method into a
single variable with enhanced tagging power. Its performance was tested with
data, using a large sample of reconstructed semileptonic $B \to \mu \dzero X$
and $B \to \mu \dst X$ decays, corresponding to an integrated luminosity of
approximately 1 fb$^{-1}$. The events were divided into groups depending on the
value of the combined tagging variable, and an independent analysis was
performed in each group. Combining the results of these analyses, the overall
effective tagging power was found to be eD^2 = (2.48 \pm 0.21 (stat.)
^{+0.08}_{-0.06} (syst.))%. The measured $B^0_d$ mixing frequency dmd = 0.506
\pm 0.020 {\rm (stat) \pm 0.016 (syst) ps}^{-1} is in good agreement with the
world average value.


title: Eta and eta' mesons production at COSY-11

abstract:
  The low emittance and small momentum spread of the proton and deuteron beams
of the Cooler Synchrotron COSY combined with the high mass resolution of the
COSY-11 detection system permit to study the creation of mesons in the
nucleon-nucleon interaction down to the fraction of MeV with respect to the
kinematical threshold. At such small excess energies, the ejectiles possess low
relative momenta and are predominantly produced with the relative angular
momentum equal to zero. Taking advantage of these conditions we have performed
investigations aiming to determine the mechanism of the production of eta and
eta' mesons in the collision of hadrons as well as the hadronic interaction of
these mesons with nucleons and nuclei. In this proceedings we address the
ongoing studies of the spin and isospin dependence for the production of the
eta and eta' mesons in free and quasi-free nucleon-nucleon collisions. New
results on the spin observables for the vec(p)p --> pp eta reaction, combined
with the previously determined total cross section isospin dependence, reveal a
statistically significant indication that the excitation of the nucleon to the
S11(1535) resonance, the process which intermediates the production of the eta
meson in the nucleon-nucleon interactions, is predominantly due to the exchange
of the pi meson between the colliding nucleons.


title: $\eta$ meson reconstruction in pp reactions at 2.2 GeV with HADES

abstract:
  The HADES spectrometer installed at GSI Darmstadt is devoted to study the
production of di-electron pairs from proton, pion and nucleus induced reactions
at 1-2 AGeV. In pp collisions at 2.2 GeV we have focused mainly on exclusive
reconstruction of the $\eta$ meson decays in the hadronic
($\eta\to\pi^{+}\pi^{-}\pi^{0}$) and the electromagnetic channels ($\eta\to
e^{+}e^{-}\gamma$). We present analysis techniques and discuss first results on
$\eta$ production, with the main focus on comparisons of reconstructed
distributions to results obtained by other experiments and theoretical
predictions.


title:
Direct Photon Production in p+p and d+Au Collisions Measured with the
  PHENIX Experiment

abstract:
  Direct photon yield measured in p+p and d+Au collisions at \sqrt{s} = 200 GeV
with the PHENIX experiment is presented and compared to pQCD predictions. In
the case of p+p collisions both the inclusive and isolated direct photon
production cross-sections are measured. Relative contribution of isolated
direct photons is somewhat below but still agree within errors with pQCD
predictions. In the case of d+Au collisions no modifications due to presence of
cold matter are found within errors.


title: The Deuteron Spin-dependent Structure Function g1d and its First Moment

abstract:
  We present a measurement of the deuteron spin-dependent structure function
g1d based on the data collected by the COMPASS experiment at CERN during the
years 2002-2004. The data provide an accurate evaluation for Gamma_1^d, the
first moment of g1d(x), and for the matrix element of the singlet axial
current, a0. The results of QCD fits in the next to leading order (NLO) on all
g1 deep inelastic scattering data are also presented. They provide two
solutions with the gluon spin distribution function Delta G positive or
negative, which describe the data equally well. In both cases, at Q^2 = 3
(GeV/c)^2 the first moment of Delta G is found to be of the order of 0.2 - 0.3
in absolute value.

Precise determination of the spin structure function $\mathbf{g_1}$ of
  the proton, deuteron and neutron

abstract:
  Precise measurements of the spin structure functions of the proton
$g_1^p(x,Q^2)$ and deuteron $g_1^d(x,Q^2)$ are presented over the kinematic
range $0.0041 \leq x \leq 0.9$ and $0.18 $ GeV$^2$ $\leq Q^2 \leq 20$ GeV$^2$.
The data were collected at the HERMES experiment at DESY, in deep-inelastic
scattering of 27.6 GeV longitudinally polarized positrons off longitudinally
polarized hydrogen and deuterium gas targets internal to the HERA storage ring.
The neutron spin structure function $g_1^n$ is extracted by combining proton
and deuteron data. The integrals of $g_1^{p,d}$ at $Q^2=5$ GeV$^2$ are
evaluated over the measured $x$ range. Neglecting any possible contribution to
the $g_1^d$ integral from the region $x \leq 0.021$, a value of $0.330 \pm
0.011\mathrm{(theo.)}\pm0.025\mathrm{(exp.)}\pm 0.028$(evol.) is obtained for
the flavor-singlet axial charge $a_0$ in a leading-twist NNLO analysis.


title: Observation of Bs-Bsbar Oscillations

abstract:
  We report the observation of Bs-Bsbar oscillations from a time-dependent
measurement of the Bs-Bsbar oscillation frequency Delta ms. Using a data sample
of 1 fb^-1 of p-pbar collisions at sqrt{s}=1.96 TeV collected with the CDF II
detector at the Fermilab Tevatron, we find signals of 5600 fully reconstructed
hadronic Bs decays, 3100 partially reconstructed hadronic Bs decays, and 61500
partially reconstructed semileptonic Bs decays. We measure the probability as a
function of proper decay time that the Bs decays with the same, or opposite,
flavor as the flavor at production, and we find a signal for Bs-Bsbar
oscillations. The probability that random fluctuations could produce a
comparable signal is 8 X 10^-8, which exceeds 5 sigma significance. We measure
  Delta ms = 17.77 +- 0.10 (stat) +- 0.07 (syst) ps^-1
  and extract
  |Vtd/Vts| = 0.2060 +- 0.0007 (exp) + 0.0081 - 0.0060 (theor).


title:
Earth Radioactivity Measurements with a Deep Ocean Anti-neutrino
  Observatory

abstract:
  We consider the detector size, location, depth, background, and radio-purity
required of a mid-Pacific deep-ocean instrument to accomplish the twin goals of
making a definitive measurement of the electron anti-neutrino flux due to
uranium and thorium decays from Earth's mantle and core, and of testing the
hypothesis for a natural nuclear reactor at the core of Earth. We take the
experience with the KamLAND detector in Japan as our baseline for sensitivity
and background estimates. We conclude that an instrument adequate to accomplish
these tasks should have an exposure of at least 10 kilotonne-years (kT-y),
should be placed at least at 4 km depth, may be located close to the Hawaiian
Islands (no significant background from them), and should aim for KamLAND
radio-purity levels, except for radon where it should be improved by a factor
of at least 100. With an exposure of 10 kT-y we should achieve a 24%
measurement of the U/Th content of the mantle plus core. Exposure at multiple
ocean locations for testing lateral heterogeneity is possible.


title:
A study of gamma gamma -> Ks Ks production at energies of 2.4-4.0GeV at
  Belle

abstract:
  $K^0_SK^0_S$ production in two-photon collisions has been studied using a
397.6 fb$^{-1}$ data sample collected with the Belle detector at the KEKB
$e^+e^-$ collider. For the first time the cross sections are measured in the
two-photon center-of-mass energy range between 2.4 GeV and 4.0 GeV and angular
range $|\cos\theta^*|<0.6$. Combining the results with measurements of
$\gamma\gamma\to K^+K^-$ from Belle, we observe that the cross section ratio
$\sigma(K^0_SK^0_S)/\sigma(K^+K^-)$ decreases from ~0.13 to ~0.01 with
increasing energy. Signals for the $\chi_{c0}$ and $\chi_{c2}$ charmonium
states are also observed.

Prospects of the measurement of Bs0 oscillations with the ATLAS detector
  at LHC

abstract:
  An estimation of the sensitivity to measure Bs-Bsbar oscillations with the
ATLAS detector is given for the detector geometry of initial layout. The delta
ms reach is derived from unbinned maximum likelihood amplitude fits using Bs0
events generated with a simplified Monte Carlo method.


title: Measurement of the W boson helicity in top quark decay at D0

abstract:
  We present a measurement of the fraction f_+ of right-handed W bosons
produced in top quark decays, based on a candidate sample of ttbar events in
the l+jets and dilepton decay channels corresponding to an integrated
luminosity of 370 pb^-1 collected by the DO detector at the Fermilab Tevatron
ppbar Collider at sqrt{s}=1.96 TeV. We reconstruct the decay angle theta^* for
each lepton. By comparing the \cos\theta^* distribution from the data with
those for the expected background and signal for various values of f_+, we find
$f_+=0.056 +- 0.080 (stat) +- 0.057 (syst)}. (f_+ < 0.23 at 95% C.L.),
consistent with the standard model prediction of f_+=3.6 x10^-4.


title: A Review of Charm Semileptonic Decays

abstract:
  Several high energy experiments have been actively pursuing the analyses of
semileptonic decays of charm mesons, resulting in numerous new results and
publications. In this report, we summarize the recent efforts on the topics of
pseudoscalar and vector charm semileptonic decays, especially in the area of
branching fractions and form factor measurements.


title: Observation of the decay $B^0 \to J/\psi \eta$

abstract:
  We report the first observation of $B^0 \to J/\psi \eta$ decay. These results
are obtained from a data sample that contains 449 million $B\bar{B}$ pairs
accumulated at the $\Upsilon(4S)$ resonance with the Belle detector at the KEKB
asymmetric-energy $e^+ e^-$ collider. We observe a signal with a significance
of 8.1$\sigma$ and obtain a branching fraction of (9.5 $\pm$ 1.7 (stat) $\pm$
0.8 (syst))$\times 10^{-6}$.


title:
Studies of $\gamma\gamma\to\Lambda\bar{\Lambda},\Sigma^0\bar{\Sigma^0}$
  production at Belle

abstract:
  Cross sections for hyperon pair production from two-photon collisions,
$\gamma\gamma\to\Lambda\bar{\Lambda},\Sigma^0\bar{\Sigma^0}$, are measured in
the 2-4 GeV energy region at Belle, using 464 fb$^{-1}$ of data. A contribution
from the intermediate resonance $\eta_c(1S)$ is observed, and the products of
the two-photon width of the $\eta_c(1S)$ and its branching ratios to
$\Lambda\bar{\Lambda}$ and $\Sigma^0\bar{\Sigma^0}$ are measured. The results
will help test QCD models.


title: A New Search for tau -> mu gamma and tau -> e gamma Decays at Belle

abstract:
  We update our search for the lepton flavor violating tau -> mu gamma and tau
-> e gamma decays based on 535/fb of data accumulated at the Belle experiment.
No signal is found and we set preliminary 90% confidence level upper limits:
B(tau -> mu gamma) < 4.5x 10^-8 and B(tau -> e gamma) < 1.2x 10^-7.


title: Measurement of open beauty production at HERA in the D* muon final state

abstract:
  The production of beauty quarks with a D*+- and a muon in the final state has
been measured with the ZEUS detector at HERA using an integrated luminosity of
114 pb-1. Low transverse-momentum thresholds for the muon and D* meson allow a
measurement of beauty production closer to the production threshold than
previous measurements. The beauty signal was extracted using the charge
correlations and angular distributions of the muon with respect to the D*
meson. Cross sections for photoproduction and deep inelastic scattering are
somewhat higher than, but compatible with, next-to-leading-order QCD
predictions, and compatible with other measurements.


title:
Fermion pair production in e+e- collisions at 189-209 GeV and
  constraints on physics beyond the Standard Model

abstract:
  Cross sections, angular distributions and forward-backward asymmetries are
presented, of two-fermion events produced in e+e- collisions at centre-of-mass
energies from 189 to 209 GeV at LEP, measured with the ALEPH detector. Results
for e+e-, mu+mu-, tau+tau-, qq, bb and cc production are in agreement with the
Standard Model predictions. Constraints are set on scenarios of new physics
such as four-fermion contact interactions, leptoquarks, Z' bosons, TeV-scale
quantum gravity and R-parity violating squarks and sneutrinos.


title: Observation of CP violation in B^0 -> eta' K^0 Decays

abstract:
  We present measurements of the time-dependent CP-violation parameters S and C
in B^0 --> eta' K^0 decays. The data sample corresponds to 384 million B Bar
pairs produced by e^+ e^- annihilation at the Y(4S). The results are S = 0.58
+- 0.10 +- 0.03 and C = -0.16 +- 0.07 +- 0.03. We observe mixing-induced CP
violation with a significance of 5.5 standard deviations in this b -> s penguin
dominated mode.


title:
Measurement of the top quark mass in the lepton+jets final state with
  the matrix element method

abstract:
  We present a measurement of the top quark mass with the Matrix Element method
in the lepton+jets final state. As the energy scale for calorimeter jets
represents the dominant source of systematic uncertainty, the Matrix Element
likelihood is extended by an additional parameter, which is defined as a global
multiplicative factor applied to the standard energy scale. The top quark mass
is obtained from a fit that yields the combined statistical and systematic jet
energy scale uncertainty. Using a data set of 370 pb-1 taken with the D0
experiment at Run II of the Fermilab Tevatron Collider, the mass of the top
quark is measured using topological information to be: mtop(topo) = 169.2
+5.0-7.4 (stat.+JES) +1.5-1.4 (syst.) GeV, and when information about
identified $b$ jets is included: mtop(b-tag) = 170.3 +4.1-4.5 (stat.+JES)
+1.2-1.8 (syst.) GeV. The measurements yield a jet energy scale consistent with
the reference scale.


title:
Study of Inclusive Strange-Baryon Production and Search for Pentaquarks
  in Two-Photon Collisions at LEP

abstract:
  Measurements of inclusive production of the Lambda, Xi- and Xi*(1530) baryons
in two-photon collisions with the L3 detector at LEP are presented. The
inclusive differential cross sections for Lambda and Xi- are measured as a
function of the baryon transverse momentum, pt, and pseudo-rapidity, eta. The
mean number of Lambda, Xi- and Xi*(1530) baryons per hadronic two-photon event
is determined in the kinematic range 0.4 GeV < pt< 2.5 GeV, |eta| < 1.2.
Overall agreement with the theoretical models and Monte Carlo predictions is
observed. A search for inclusive production of the pentaquark theta+(1540) in
two-photon collisions through the decay theta+ -> proton K0s is also presented.
No evidence for production of this state is found.

Comment on "An Improved Experimental Limit on the Electric-Dipole Moment
  of the Neutron," C.A.Baker et al [hep-ex/0602020]

abstract:
  We point out that the rotation of the Earth leads to a non-negligible
apparent electric-dipole moment effect for this experiment.


title: Measurement of the top quark mass in the dilepton channel

abstract:
  We present a measurement of the top quark mass in the dilepton channel based
on approximately 370/pb of data collected by the D0 experiment during Run II of
the Fermilab Tevatron collider. We employ two different methods to extract the
top quark mass. We show that both methods yield consistent results using
ensemble tests of events generated with the D0 Monte Carlo simulation. We
combine the results from the two methods to obtain a top quark mass m_t = 178.1
+/- 8.2 GeV. The statistical uncertainty is 6.7 GeV and the systematic
uncertainty is 4.8 GeV.


title: Proposal to upgrade the MIPP Experiment

abstract:
  The upgraded MIPP physics results are needed for the support of NuMI
projects, atmospheric cosmic ray and neutrino programs worldwide and will
permit a systematic study of non-perturbative QCD interctions. The MIPP TPC is
the largest contributor to the MIPP event size by far. Its readout system and
electronics were designed in the 1990's and limit it to a readout rate of 60 Hz
in simple events and ~20 Hz in complicated events. With the readout chips
designed for the ALICE collaboration at the LHC, we propose a low cost scheme
of upgrading the MIPP data acquisition speed to 3000 Hz. This will also enable
us to measure the medium energy numi target to be used for the NOvA/MINERvA
experiments. We outline the capabilities of the upgraded MIPP detector to
obtain high statistics particle production data on a number of nuclei that will
help towards the understanding and simulation of hadronic showers in matter.
Measurements of nitrogen cross sections will permit a better understanding of
cosmic ray shower systematics in the atmosphere. In addition, we explore the
possibilities of providing tagged neutral beams using the MIPP spectrometer
that may be crucial for validating the Particle Flow Algorithm proposed for
calorimeters for the International Linear Collider detectors. Lastly, we
outline the physics potential of such a detector in understanding
non-perturbative QCD processes.


title:
Measurement of double beta decay of 100Mo to excited states in the NEMO
  3 experiment

abstract:
  The double beta decay of 100Mo to the 0^+_1 and 2^+_1 excited states of 100Ru
is studied using the NEMO 3 data. After the analysis of 8024 h of data the
half-life for the two-neutrino double beta decay of 100Mo to the excited 0^+_1
state is measured to be T^(2nu)_1/2 = [5.7^{+1.3}_{-0.9}(stat)+/-0.8(syst)]x
10^20 y. The signal-to-background ratio is equal to 3. Information about energy
and angular distributions of emitted electrons is also obtained. No evidence
for neutrinoless double beta decay to the excited 0^+_1 state has been found.
The corresponding half-life limit is T^(0nu)_1/2(0^+ --> 0^+_1) > 8.9 x 10^22 y
(at 90% C.L.).
  The search for the double beta decay to the 2^+_1 excited state has allowed
the determination of limits on the half-life for the two neutrino mode
T^(2nu)_1/2(0^+ --> 2^+_1) > 1.1 x 10^21 y (at 90% C.L.) and for the
neutrinoless mode T^(0nu)_1/2(0^+ --> 2^+_1) > 1.6 x 10^23 y (at 90% C.L.).


title: An Improved Limit on Invisible Decays of Positronium

abstract:
  The results of a new search for positronium decays into invisible final
states are reported. Convincing detection of this decay mode would be a strong
evid ence for new physics beyond the Standard Model (SM): for example the
existence of extra--dimensions, of milli-charged particles, of new light gauge
bosons or of mirror particles. Mirror matter could be a relevant dark matter
candidate.
  In this paper the setup and the results of a new experiment are presented. In
a collected sample of about $(6.31\pm0.28) \times 10^6$ orthopositronium decay
s, no evidence for invisible decays in an energy window [0,80] keV was found
and an upper limit on the branching ratio of orthopositronium \invdecay could
be set: $\binvdecay<4.2\times 10^{-7}$ (90% C.L.)
  Our results provide a limit on the photon mirror-photon mixing strength
$\epsilon \leq 1.55\times 10^{-7}$ (90% C.L.) and rule out particles lighter
than the electron mass with a fraction $Q_x \leq 3.4 \times 10^{-5}$ of the
electron charge. Furthermore, upper limits on the branching ratios for the
decay of parapositronium $Br(p-Ps\to invisible)\leq 4.3 \times 10^{-7}$ (90%
C.L.) and the direct annihilation $Br(e^+e^-\to invisible)\leq 2.1 \times
10^{-8}$ (90% C.L.) could be set.


title: Searches for New Phenomena at the Tevatron and at HERA

abstract:
  Recent results on searches for new physics at Run II of the Tevatron and
highlights from HERA are reported. The searches cover many different final
states and a wide range of models. All analyses have at this point led to
negative results, but some interesting anomalies have been found.


title: D0 QCD studies

abstract:
  A number of recent measurements from D0 that can be used to constrain parton
distributions and tune QCD Monte Carlo models are presented. The selection
includes W charge asymmetry, Z+jet event properties, dijet azimuthal
decorrelations and the inclusive jet cross section.


title: Measurements of exclusive B_s^0 decays at the Y(5S) resonance

abstract:
  Several exclusive $B_s^0$ decays are studied using a 1.86 fb-1 data sample
collected at the Y(5S) resonance with the Belle detector at the KEKB asymmetric
energy e^+ e^- collider. In the $B_s^0 \to D_s^- \pi^+$ decay mode we find 10
$B_s^0$ candidates and measure the corresponding branching fraction. Combining
the B_s^0 -> D_s^{(*)-} \pi^+, B_s^0 -> D_s^{(*)-} \rho^+, B_s^0 -> J/\psi \phi
and B_s^0 -> J/\psi \eta decay modes, a significant $B_s^0$ signal is observed.
The ratio \sigma (e^+ e^- -> B_s^* \bar{B}_s^*) / \sigma (e^+ e^- -> B_s^{(*)}
\bar{B}_s^{(*)}) = (93^{+7}_{-9} \pm 1)% is obtained at the Y(5S) energy,
indicating that $B_s^0$ meson production proceeds predominantly through the
creation of $B^*_s \bar{B}^*_s$ pairs. The $B_s^0$ and $B_s^*$ meson masses are
measured to be M(B_s^0)=(5370 \pm 1 \pm 3)MeV/c^2 and M(B_s^*)=(5418 \pm 1 \pm
3)MeV/c^2. Upper limits on the B_s^0 -> \gamma \gamma, B_s^0 -> \phi \gamma,
B_s^0 -> K^+ K^- and B_s^0 -> D_s^{(*)+} D_s^{(*)-} branching fractions are
also reported.


title: Longitudinal Double Spin Asymmetry in Inclusive Jet Production at STAR

abstract:
  This contribution reports on the first measurement of the longitudinal
double-spin asymmetry $A_{LL}$ for the inclusive production of jets in
polarized proton-proton collisions at $\sqrt{s}=200 \mathrm{GeV}$. The data
were collected with STAR at RHIC in the years 2003 and 2004, and correspond to
a sampled integrated luminosity of $0.3 \mathrm{pb}^{-1}$ with beam
polarizations up to 45%. The results on $A_{LL}$ cover jet transverse momenta
$5 < p_{T} < 17 \mathrm{GeV/c}$ and agree with perturbative QCD evaluations
based on deep-inelastic scattering parametrizations for the gluon polarization
in the proton. The results disfavor large positive gluon polarization in the
polarized proton.


title: Recent Studies of Little Higgs Models in ATLAS

abstract:
  The ATLAS Collaboration at the LHC continues investigating the possibility to
detect particles predicted by Little Higgs models. In this talk, the latest
results on the Z/W h decays and on the hadronic decays of the new gauge bosons
Z_H/W_H are reviewed.


title: Rare B decays and new physics studies

abstract:
  I present a review of using rare B decays to search for physics beyond the
Standard Model. B decays that proceed either through annihilation or loop
topologies at leading order in the Standard Model provide unique probes in the
search for new physics. The latest experimental results from the B factories
(Babar and Belle) and the Tevatron experiments (CDF and D0) on rare decays and
their impact on various scenarios for new physics will be presented.


title: CP Violation measurements in B to charm decays at BaBar

abstract:
  This article summarises measurements of time-dependent CP asymmetries in
decays of neutral B mesons to charm final states using data collected by the
BaBar detector at the PEP-II asymmetric-energy B-factory. All results are
preliminary unless otherwise stated.


title:
Measurement of Inclusive Production of eta, eta' and phi Mesons in D0,
  D+ and Ds+ Decays

abstract:
  We measure the inclusive branching fractions of charm mesons into three
mesons with large s-anti-s content, namely the eta, eta' and phi. Data were
accumulated with the CLEO-c detector. For D0 and D+ rates, we use 281/pb taken
on the psi(3770) resonance, and for Ds+ rates, we use 195/pb taken at 4170 MeV.
We find that the production rates of these particles are larger in Ds+ decays
than in D0 and D+ decays. The phi rate, in particular, is 15 times greater.
These branching fractions can be used to measure Bs yields either at the
Upsilon(5S) resonance or at hadron colliders.


title: Search for R-Parity violating Supersymmetry with the D0 Detector

abstract:
  Searches for R-parity violating supersymmetry with the D0 detector at the
Fermilab Tevatron ppbar-collider are presented. In the case of non-zero LLE
couplings lambda_ijk>=0.01, multi-lepton final states, and for a small coupling
lambda_122<<0.01 di-muon final states are studied. The case of non-zero LQD
coupling lambda'_211 leads to final states with two muons and jets. A total
integrated luminosity of 0.38 fb-1 collected between April 2002 and August 2004
is utilized. The observed numbers of events are in agreement with the Standard
Model expectation, and limits on RPV supersymmetry are derived, extending
significantly previous bounds.


title: The Physics of Charm: Recent Experimental Results

abstract:
  We review the most recent results from experiments studying systems
containing charmed quarks. The selection reflects the presenter's bias, and
there is an emphasis on decays of open charm. We discuss precision measurements
of various sorts, various new states in the charmonium system, measurements
aimed at testing Lattice QCD, and the latest searches for charm mixing. We
conclude with a discussion of upcoming experiments at existing and future
facilities.


title: Charmonium Review

abstract:
  During the last few years there has been a renaissance in charm and
charmonium spectroscopy with higher precision measurements at the $\psi^{'}$
and $\psi(3770)$ coming from BESII and CLEOc and many new discoveries coming
from B-factories. In this paper, I will review the status of $\psi(3770)$ and
below.


title:
Moments of the electron energy spectrum and partial branching fraction
  of $B \to X_c e \nu$ decays at Belle

abstract:
  We report a measurement of the inclusive electron energy spectrum for charmed
semileptonic decays of B mesons in a 140fb-1 data sample collected at the
\Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric energy e+
e- collider. We determine the first four moments of the electron energy
spectrum for threshold values of the electron energy between 0.4 and 2.0 GeV.
In addition, we provide values of the partial branching fraction (zeroth
moment) for the same electron threshold energies, and independent measurements
of the B+ and B0 partial branching fractions at 0.4 GeV and 0.6 GeV electron
threshold energies. We measure the independent B+ and B^0 partial branching
fractions with electron threshold energies of 0.4 GeV to be \Delta \mathcal{B}
(B+ -> X_c e \nu)=(10.79 +/- 0.25(stat.) +/- 0.27(sys.))% and \Delta
\mathcal{B} (B0 -> X_c e \nu)=(10.09 +/- 0.30(stat.) +/- 0.22(sys.))%. Full
correlations between all measurements are evaluated.


title: Measurement of alpha_S in e+e- collisions at LEP and JADE

abstract:
  Data from e+e- annihilation into hadrons collected by the JADE, the L3 and
the OPAL experiment at centre-of-mass energies between 14 GeV and 209 GeV are
used to determine the strong coupling alpha_S. Observables in leading order
sensitive to alpha_S as well as alpha_S**2 are used. The evolution of alpha_S
with respect to the centre-of-mass energy as predicted by QCD is studied and
confirmed with high precision. All measurements of alpha_S are consistent with
the current world average.

for charmless hadronic B decays using BABAR detector at the PEP-II B-factory.


title:
Measurement of the e+e- -> pi+pi- cross section with the CMD-2 detector
  in the 370-520 MeV c.m. energy range

abstract:
  The cross section of the process e+e- -> pi+pi- has been measured at the
CMD-2 detector in the 370-520 MeV center-of-mass (c.m.) energy range. A
systematic uncertainty of the measurement is 0.7 %. Using all CMD-2 data on the
pion form factor, the pion electromagnetic radius was calculated. The cross
section of muon pair production was also determined.


title: QCD and Top-Quark Results from the Tevatron

abstract:
  Selected recent QCD and top-quark results from the Tevatron are reviewed,
aiming to illustrate progression from basic studies of QCD processes to
verification of perturbative calculations and Monte Carlo simulation tools, and
to their applications in more novel and complex cases, like top-quark studies
and searches for new physics.


title:
A Structure at 2175 MeV in $e^+ e^- \to \phi f_0(980)$ Observed via
  Initial-State Radiation

abstract:
  We study the initial-state-radiation processes $e^+ e^- \to K^+
K^-\pi^+\pi^-\gamma$ and $e^+ e^- \to K^+ K^-\pi^0\pi^0\gamma$ using an
integrated luminosity of 232 fb$^{-1}$ collected at the $\Upsilon(4S)$ mass
with the BaBar detector at SLAC. Even though these reactions are dominated by
intermediate states with excited kaons, we are able to study for the first time
the cross section for $e^+ e^- \to \phi(1020) f_{0}(980)$ as a function of
center-of-mass energy. We observe a structure near threshold consistent with a
$1^{--}$ resonance with mass $m = 2.175 \pm 0.010\pm 0.015 GeV/c^2$ and width
$\Gamma = 58\pm 16\pm 20 MeV$. We observe no Y(4260) signal and set a limit of
$BR_{Y\to\phi\pi^+\pi^-}\cdot\Gamma^{Y}_{ee}<0.4$ eV (90% confidence level),
which excludes some models.


title:
Direct Measurements of the Branching Fractions for the Semileptonic
  Decays $D^0 \to K^-\mu^+\nu_\mu$ and $D^0 \to \pi^-\mu^+\nu_\mu$

abstract:
  Based on the data sample of 33 pb$^{-1}$ collected at and around 3.773 GeV
with the BES-II detector at the BEPC collider, the absolute branching fractions
for the semileptonic decays $D^0\to K^-\mu^+\nu_\mu$ and
$D^0\to\pi^-\mu^+\nu_\mu$ have been measured. In the system recoiling against
$7584\pm198\pm341$ singly tagged $\bar D^0$ mesons, $87.2\pm13.6$ events for
$D^0\to K^-\mu^+\nu_\mu$ and $9.3\pm7.4$ events for $D^0\to\pi^-\mu^+\nu_\mu$
are observed. These yield the absolute branching fractions to be $BF(D^0\to
K^-\mu ^+\nu_\mu)= (3.55\pm0.56\pm0.59)%$ and $BF(D^0\to\pi^-\mu^+\nu_\mu)=
(0.38\pm0.30\pm0.10)%$. The measured branching fraction for $D^0\to K^-\mu
^+\nu_\mu$ was previously used to determine the ratio $\Gamma(D^0\to
K^-\mu^+\nu_\mu)/ \Gamma(D^+\to \bar K^0\mu^+\nu_\mu)$ combining the previously
measured branching fraction for $D^+\to \bar K^0\mu^+\nu_\mu$ by the BES
Collaboration.


title:
Direct measurement of the absolute branching fraction for $D^+ \to {\bar
  K}^0\mu^+\nu_\mu$ and determination of $ \Gamma (D^0 \to
  K^-\mu^+\nu_\mu)/\Gamma (D^+ \to {\bar K}^0\mu^+\nu_\mu)$

abstract:
  The absolute branching fraction for the decay $D^+ \to {\bar
K}^0\mu^+\nu_\mu$ is determined using $5321 \pm 149 \pm160$ singly tagged $D^-$
sample from the data collected around 3.773 GeV with the BESII detector at the
BEPC collider. In the system recoiling against the singly tagged $D^-$ mesons,
$28.7 \pm 6.4$ events for $D^+ \to {\bar K}^0\mu^+\nu_\mu$ are observed. These
yield the absolute branching fraction to be $BF(D^+ \to {\bar K}^0\mu^+\nu_\mu)
= (10.3\pm2.3\pm0.8)%$. The ratio of the two partial widths for the decays $D^0
\to K^-\mu^+\nu_\mu$ and $D^+ \to {\bar K}^0\mu^+\nu_\mu$ is determined to be
$\Gamma (D^0 \to K^-\mu^+\nu_\mu)/\Gamma (D^+ \to {\bar K}^0\mu^+\nu_\mu) =
0.87 \pm 0.24 \pm 0.15$.

High-statistics measurement of the pion form factor in the rho-meson
  energy range with the CMD-2 detector

abstract:
  We present a measurement of the pion form factor based on e+e- annihilation
data from the CMD-2 detector in the energy range 0.6<sqrt(s)<1.0 GeV with a
systematic uncertainty of 0.8%. A data sample is five times larger than that
used in our previous measurement.


title:
Study of tensor states in the reaction $\gamma\gamma \to
  \pi^+\pi^-\pi^0$

abstract:
  A high statistics study of the reaction $\gamma\gamma\to \pi^+\pi^-\pi^0$ has
been performed with the Belle detector using a data sample of 26 fb$^{-1}$
collected at $\sqrt{s}=10.58\GeVcsq$. A spin-parity analysis shows dominance of
the $J^P=2^+$ helicity 2 wave for three-pion invariant masses from 1 to 3
\GeVcsq. The invariant mass distribution exhibits $a_2(1320)$, $a_2(1700)$ and
higher mass enhancements.


title: Production of $\sigma$ in $\psi(2S)\to \pi^{+}\pi^{-}J/\psi$

abstract:
  Using 14M $\psi(2S)$ events accumulated by BESII at the BEPC, a Covariant
Helicity Amplitude Analysis is performed for $\psi(2S)\to\pi^+\pi^-J/\psi,
J/\psi\to \mu^+\mu^-$. The $\pi^+\pi^-$ mass spectrum, distinctly different
from phase space, suggests $\sigma$ production in this process. Two different
theoretical schemes are used in the global fit to the data. The results are
consistent with the existence of the $\sigma$. The $\sigma$ pole position is
determined to be $(552^{+84}_{-106})-i(232^{+81}_{-72})$ MeV/$c^2$.


title: Measuring Sin^22\theta_13 with the Daya Bay Nuclear Reactors

abstract:
  Angle \theta_13 is one of the two unknown neutrino mixing parameters to be
determined. Its value may determine the future trend of the neutrino physics.
We propose to measure sin^22\theta_13 with a sensitivity better than 0.01 (90%
C.L) at the Daya Bay reactor power plant.


title: NEMO-3 double beta decay experiment: lastest results

abstract:
  Latest results on $0\nu\beta\beta$, $0\nu\chi^0\beta\beta$ and
$2\nu\beta\beta$ decays of different isotopes from NEMO-3 double beta decay
experiment are presented. In particular, new limits at 90% C.L. on neurtinoless
double beta decay of $^{100}Mo$ and $^{82}Se$ have been obtained, $T_{1/2} >
5.8\times 10^{23}$ y and $T_{1/2} > 2.1\times 10^{23}$ y, respectively.


title: Measurement OF Ds+ -> l+ nu and the Decay Constant fDs

abstract:
  I report preliminary CLEO-c results on purely leptonic decays of the Ds using
195/pb of data at 4.170 GeV. We measure fDs = 280.1 +/- 11.6 +/- 6.0 MeV, and
fDs/fD+ = 1.26 +/- 0.11 +/- 0.03.


title:
Branching fraction measurement of B0 --> D(*)- pi+, B- --> D(*)0 pi- and
  isospin analysis of B --> D(*) pi decays

abstract:
  Using 65 million $\Upsilon(4S)\to B\bar{B}$ events collected with the BABAR
detector at the PEP-II $e^{+}e^{-}$ storage ring at the Stanford Linear
Accelerator Center, we measure the color-favored branching fractions ${\cal
B}(\bar{B^{0}} \to D^{+} \pi^{-}) = (2.55 \pm 0.05 \pm 0.16)\times 10^{-3}$,
${\cal B}(\bar{B^{0}} \to D^{*+} \pi^{-}) = (2.79 \pm 0.08 \pm 0.17)\times
10^{-3}$, ${\cal B}(B^{-} \to D^{0} \pi^{-}) = (4.90 \pm 0.07 \pm 0.22)\times
10^{-3}$ and ${\cal B}(B^{-} \to D^{*0} \pi^{-}) = (5.52 \pm 0.17 \pm
0.42)\times 10^{-3}$, where the first error is statistical and the second is
systematic. With these results and the current world average for the branching
fraction for the color-suppressed decay $\bar{B^{0}} \to D^{(*)0}\pi^{0}$, the
cosines of the strong phase difference $\delta$ between the $I=1/2$ and $I=3/2$
isospin amplitudes are determined to be $ \cos \delta =
0.872^{+0.008+0.031}_{-0.007-0.029}$ for the $\bar{B} \to D\pi$ process and $
\cos \delta = 0.924^{+0.019+0.063}_{-0.017-0.054}$ for the $\bar{B} \to
D^{*}\pi$ process. Under the isospin symmetry, the results for $\cos \delta$
suggest that final-state interactions are present in the $D\pi$ system.


title: Tau Physics from B Factories

abstract:
  Some recent $\tau$-physics results are presented from the BaBar and Belle
experiments at the SLAC and KEK B factories, which produce copious numbers of
$\tau$-lepton pairs. Measurements of the tau mass and lifetime allow to test
lepton universality and CPT invariance, while searches for lepton-flavour
violation in tau decays are powerful ways to look for physics beyond the
Standard Model. In semihadronic, non-strange tau decays, the vector hadronic
final state is particularly important in helping determine the hadronic
corrections to the anomalous magnetic moment of the muon, while studies of
strange final states are the best available ways to measure the CKM matrix
element $V_{\rm us}$ and the mass of the strange quark.


title: Measurement of phi_3 with Dalitz Plot Analysis of B+=>D(*)K(*)+ Decay

abstract:
  Results from the Belle and BaBar experiments on measurement of the weak angle
phi_3 using a Dalitz plot analysis of the KSpi+pi- decay of the neutral D meson
from the B+=>D(*)K(*)+ process are presented. The method employs the
interference between D0 and D0bar to extract the angle phi_3, strong phase
delta and the ratio r of suppressed and allowed amplitudes.


title:
Single Transverse-Spin Asymmetry in Very Forward and Very Backward
  Neutral Particle Production for Polarized Proton Collisions at sqrt{s} = 200
  GeV

abstract:
  In the 2001-2002 running period of the Relativistic Heavy Ion Collider
(RHIC), transversely polarized protons were accelerated to 100 GeV for the
first time, with collisions at sqrt{s} = 200 GeV. We present results from this
run for single transverse spin asymmetries for inclusive production of neutral
pions, photons and neutrons of the energy region 20 - 100 GeV for forward and
backward production for angles between 0.3 mrad and 2.2 mrad with respect to
the polarized proton direction. An asymmetry of A_N = (-0.090 +- 0.006 +-
0.009) x (1.0^{+0.47}_{-0.24}) was observed for forward neutron production,
where the errors are statistical and systematic, and the scale error is from
the beam polarization uncertainty. The forward photon and pi^0, and backward
neutron, photon, and pi^0 asymmetries were consistent with zero. The large
neutron asymmetry indicates a strong interference between a spin-flip
amplitude, such as one pion exchange which dominates lower energy neutron
production, and remaining spin non-flip amplitudes such as Reggeon exchange.


title: Study of Leading Hadrons in Gluon and Quark Fragmentation

abstract:
  The study of quark jets in e+e- reactions at LEP has demonstrated that the
hadronisation process is reproduced well by the Lund string model. However, our
understanding of gluon fragmentation is less complete. In this study enriched
quark and gluon jet samples of different purities are selected in three-jet
events from hadronic decays of the Z collected by the DELPHI experiment in the
LEP runs during 1994 and 1995. The leading systems of the two kinds of jets are
defined by requiring a rapidity gap and their sum of charges is studied. An
excess of leading systems with total charge zero is found for gluon jets in all
cases, when compared to Monte Carlo Simulations with JETSET (with and without
Bose-Einstein correlations included) and ARIADNE. The corresponding leading
systems of quark jets do not exhibit such an excess. The influence of the gap
size and of the gluon purity on the effect is studied and a concentration of
the excess of neutral leading systems at low invariant masses (<~ 2 GeV/c^2) is
observed, indicating that gluon jets might have an additional hitherto
undetected fragmentation mode via a two-gluon system. This could be an
indication of a possible production of gluonic states as predicted by QCD.


title:
Improved Measurement of the Branching Fraction and Energy 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 the $\eta'$ 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, and thus an explanation
outside the realm of the Standard Model or an improved understanding of
non-perturbative QCD effects may be needed to account for this large rate.


title:
Measurements of the CKM angle beta in charmless loop-dominated B meson
  decays at BaBar

abstract:
  We report on preliminary measurements of time-dependent CP-violation
asymmetries in charmless neutral B meson decays to K+K-K0 (including resonant
decays phiK0 and f0K0), eta'K0, pi0K0s, K0sK0sK0s, K0sK0s, rho0K0s, omegaK0s.
The results are obtained from a data sample of up to 347 million BBbar pairs
produced by e+e- annihilation at the Y(4S) resonance collected with the BaBar
detector at the PEP-2 asymmetric-energy B-meson Factory at SLAC.


title:
Determination of CP and CPT violation parameters in the neutral kaon
  system using the Bell-Steinberger relation and data from the KLOE experiment

abstract:
  We present an improved determination of the CP and CPT violation parameters
Re(epsilon) and Im(delta) based on the unitarity condition (Bell-Steinberger
relation) and on recent results from the KLOE experiment. We find Re(epsilon) =
(159.6 \pm 1.3)10^-5 and Im(delta) = (0.4 \pm 2.1)10^-5, consistent with no CPT
violation.


title: Measurement of B[Y(5S)->Bs(*) anti-Bs(*)] 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 a data sample collected by the
CLEO III detector at CESR consisting of 0.423/fb on the Y(5S) resonance,
6.34/fb on the Y(4S) and 2.32/fb in the continuum below the Y(4S), we measure
B(Y(5S) -> phi X)=(13.8 +/- 0.7 {+2.3}{-1.5})% 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 determine fs = (24.6 +/-
2.9 {+11.0}{-5.3})%. We also update our previous independent measurement of fs
made using the inclusive Ds yields to now be (16.8 +/- 2.6 {+6.7}{-3.4)%, due
to 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=(21 {+6}{-3})%.


title: High Pt Jet Physics

abstract:
  In this contribution, a comprehensive review of the main aspects of high
$\pt$ jet physics in Run II at the Tevatron is presented. Recent measurements
on inclusive jet production are discussed using different jet algorithms and
covering a wide region of jet transverse momentum and jet rapidity. Several
measurements, sensitive to a proper description of soft gluon radiation and the
underlying event in hadron collisions, are shown. Finally, high $\pt$ prompt
photon measurements and studies on the production of electroweak bosons in
association with jets in the final state are discussed.


title: Measurements of the Running of the Electromagnetic Coupling at LEP

abstract:
  The study of Bhabha scattering at e^+e^- colliders probes the running of the
electromagnetic coupling. After early measurements by the VENUS collaboration
at TRISTAN and the by L3 collaboration at LEP, two recent analyses have been
performed by the OPAL and L3 collaborations. The OPAL collaboration studied
high-statistics low-angle Bhabha scattering at LEP, achieving a precise
determination of the running of alpha in the region 1.8GeV^2<-Q^2<6.1GeV^2. The
L3 collaboration investigated high-energy large-angle Bhabha scattering to
first probe the region 1800GeV^2 < -Q^2 < 21600GeV^2. All measurements are
described and a global overview of their agreement with QED predictions is
given.


title:
High statistics study of f_0(980) resonance in gamma gamma --> pi^+ pi^-
  production

abstract:
  We report on a high statistics measurement of the cross section of the
process gamma gamma to pi^+ pi^- in the center-of-mass energy range 0.8 GeV/c^2
< W < 1.5 GeV/c^2 with 85.9 fb^-1 of data collected at sqrt(s)=10.58 GeV and
10.52 GeV with the Belle detector. A clear signal for the f_0 lr 980 resonance
is observed. From a fit to the mass spectrum, the resonance's mass, pi^+ pi^-
and two-photon decay widths are found to be 985.6^+1.2
_-1.5(stat)^+1.1_-1.6(syst) MeV/c^2, 34.2^+13.9_-11.8(stat)^+8.8_-2.5(syst)
MeV, and 205^+95_-83(stat)^+147_-117(syst) eV, respectively.


title: Study of Bs->mu+mu- in CMS

abstract:
  We present a Monte Carlo simulation study of measuring the rare leptonic
decay Bs->mu+mu- with the CMS experiment at the LHC. The study is based on a
full detector simulation for signal and background events. We discuss the
high-level trigger algorithm and the offline event selection.


title: alpha(s) Determinations from Jets and Scaling Violations at HERA

abstract:
  A review is given on recent alpha(s) determinations from the H1 and ZEUS
Collaborations. These are based on measurements of jet cross sections, event
shape variables, as well as on the observed scaling violation of the structure
function F_2. A HERA average on alpha(s)(m_Z) is presented, in comparison with
world mean values.


title: Events with isolated leptons and missing transverse momentum at HERA

abstract:
  Events with isolated leptons and missing transverse momentum are searched for
in electron- or positron-proton collisions at HERA by the H1 and ZEUS
experiments. Such events may be explained within the Standard Model by W boson
production, followed by leptonic decay. The analysis performed including HERA I
and the recently collected data at HERA II results in clear evidence of W
production. However, H1 collaboration observes an excess of events in e^+p
collisions, not supported so far by ZEUS. If the difference between the H1 and
ZEUS observations is attributed to a statistical fluctuation, the combined
result exceeds the Standard Model prediction at $2.6\sigma$ level. A search for
events with tau leptons and missing transverse momentum is also presented.


title: Kaon physics

abstract:
  At present, the main topics addressed by kaon physics are the unitarity test
of CKM matrix via precision measurements of the Cabibbo angle as well as
precision tests of discrete symmetries: in particular, study of possible CPT
violations in a model-independent way through the Bell-Steinberger relation, or
through the measurement of charge asymmetries. Other interesting topics are
related to the test of predictions from chiral perturbation theory. Also status
and prospects of the $K^\pm \to \pi^\pm\nu\bar(nu)$ and $K^0\to\pi^0\nu\bar(nu)
decays are discussed.


title: Testing the Standard Model in Top Quark Decays

abstract:
  With its discovery in 1995 by the CDF and D0 collaborations the top quark
completed the set of quarks expected by the Standard Model. It is predicted to
have the same quantum numbers and couplings as the other up-type quarks.
Albeit, only very few of these properties have been verified so far. This
article summarises the existing measurements of top quark properties in the
pair production mode.


title:
Observation of $B_s^0-\bar{B}_s^0$ Oscillations and Measurement of
  $\Delta m_s$ in CDF

abstract:
  We report the observation of $\B_s^0-\bar{B}_s^0$ oscillations performed by
the CDF II detector using a data sample of 1 $fb^{-1}$ of $p\bar{p}$ collisions
at $\sqrt{s}=1.96 \TeV$. We measure the probability as a function of proper
decay time that the $B_s$ decays with the same, or opposite, flavor as the
flavor at production, and we find a signal for $\B_s^0-\bar{B}_s^0$
oscillations. The probability that random fluctuations could produce a
comparable signal is $8 \times 10^{-8}$, which exceeds $5\sigma$ significance.
We measure $\Delta m_s = 17.77 \pm{0.10} ({\rm stat}) \pm{0.07} ({\rm syst})
ps^{-1}$. A very important update has been presented by the CDF collaboration
after I gave my talk, the latest available results on $B_s$ mixing are included
here.


title:
Measurement of the Ratios of Branching Fractions B(Bs -> Ds pi pi pi) /
  B(Bd -> Dd pi pi pi) and B(Bs -> Ds pi) / B(Bd -> Dd pi)

abstract:
  Using 355 pb^-1 of data collected by the CDF II detector in \ppbar collisions
at sqrt{s} = 1.96 TeV at the Fermilab Tevatron, we study the fully
reconstructed hadronic decays B -> D pi and B -> D pi pi pi. We present the
first measurement of the ratio of branching fractions B(Bs -> Ds pi pi pi) /
B(Bd -> Dd pi pi pi) = 1.05 pm 0.10 (stat) pm 0.22 (syst). We also update our
measurement of B(Bs -> Ds pi) / B(Bd -> Dd pi) to 1.13 pm 0.08 (stat) pm 0.23
(syst) improving the statistical uncertainty by more than a factor of two. We
find B(Bs -> Ds pi) = [3.8 pm 0.3 (stat) pm 1.3 (syst)] \times 10^{-3} and B(Bs
-> Ds pi pi pi) = [8.4 pm 0.8 (stat) pm 3.2 (syst)] \times 10^{-3}.
