Search for neutral MSSM Higgs bosons decaying to tau pairs in p-pbar
  collisions at sqrt(s)=1.96 TeV

abstract:
  We present a search for neutral supersymmetric Higgs bosons decaying to tau
pairs produced in p-pbar collisions at sqrt(s) = 1.96 TeV. The data,
corresponding to 310 pb^(-1) integrated luminosity, were collected with the CDF
II detector at the Tevatron collider at Fermilab. No significant excess above
the standard model backgrounds is observed. We set exclusion limits on the
production cross section times branching fraction to tau pairs for Higgs masses
in the range from 90 to 250 GeV/c^2.

Improved Measurements of Branching Fractions and CP Asymmetries for
  B->omega h Decays

abstract:
  We report improved measurements of B to pseudoscalar-vector decays containing
an omega meson in the final state. These results are obtained from a data
sample that contains 386 millions BBbar pairs collected at the Upsilon(4S)
resonance, with the Belle detector at the KEKB asymmetric energy e^+e^-
collider. We measure the branching fractions Br(B^+/- -> omega
K^+/-)=(8.1+/-0.6+/-0.5)*10^-6, Br(B^+/- -> omega
pi^+/-)=(7.0+/-0.6+/-0.5)*10^-6, and Br(B^0 -> omega
K^0)=(3.9+/-0.7+/-0.4)*10^-6. we also set the 90% confidence level upper limit
Br(B^0 -> omega pi^0)<1.5*10^-6. In addition, we obtain the partial rate
asymmetries Acp=0.05+/-0.08+/-0.01 for B^+/- -> omega K^+/- and
Acp=-0.03+/-0.09+/-0.02 for B^+/- -> omega pi^+/-.

title:
Search for the Higgs boson in H->WW(*) decays in p anti-p collisions at
  S**(1/2) = 1.96-TEV

abstract:
  We present a search for the standard model Higgs boson in H->WW(*), decays
with ee, emu and mumu final states in p anti-p collisions at a center-of-mass
energy of S**(1/2) = 1.96-TEV. The data, collected from April 2002 to June 2004
with the D0 detector, correspond to an integrated luminosity of 300 - 325
pb**(-1), depending on the final state. The number of events observed is
consistent with the expectation from backgrounds. Limits from the combination
of all three channels on the Higgs production cross section times branching
ratio sigma*BR(H->WW(*) are presented.


title: Forward Jet Production in Deep Inelastic Scattering at HERA

abstract:
  The production of forward jets has been measured in deep inelastic ep
collisions at HERA. The results are presented in terms of single differential
cross sections as a function of the Bjorken scaling variable (x_{Bj}) and as
triple differential cross sections d^3 \sigma / dx_{Bj} dQ^2 dp_{t,jet}^2,
where Q^2 is the four momentum transfer squared and p_{t,jet}^2 is the squared
transverse momentum of the forward jet. Also cross sections for events with a
di-jet system in addition to the forward jet are measured as a function of the
rapidity separation between the forward jet and the two additional jets. The
measurements are compared with next-to-leading order QCD calculations and with
the predictions of various QCD-based models.


title:
Moments of the Electron Energy Spectrum in B --> X_c l \nu decays at
  Belle

abstract:
  We report a measurement of the inclusive electron energy spectrum for charmed
semileptonic decays of B mesons in a 140 fb^-1 data sample collected on the
Upsilon(4S) resonance, with the Belle detector at the KEKB asymmetric energy
e^+ e^- collider. We determine the first, second and third moments of the
electron energy spectrum for threshold values of the electron energy between
0.4 and 1.5 GeV.


title:
Improved Measurement of cal{B}(D^+ --> mu^+ nu) and the Pseudoscalar
  Decay Constant f_{D^+}

abstract:
  We extract a relatively precise value for the decay constant of the D+ meson
by measuring B(D+ -> mu+ nu)=(4.40 +/- 0.66 {+0.09}{-0.12}) x 10^{-4}, using
281 inverse-pb of data taken on the psi(3770) resonance with the CLEO-c
detector. We find fD+=(222.6 +/- 16.7 {+2.8}{-3.4}) MeV, and compare with
current theoretical calculations. We also set a 90% confidence upper limit on
B(D+ -> e+ nu)<2.4 x 10^{-5} which limits contributions from non-standard model
physics.


title:
A Combination of CDF and DO Limits on the Branching Ratio of B_s(d) to
  mu+ mu- Decays

abstract:
  We combine the results of CDF and DO searches for the rare decays B_s to mu+
mu- and B_d to mu+ mu-. The experiments use 364 pb-1 and 300 pb-1 of data
respectively. The limits on the branching ratios are obtained by normalizing
the estimated sensitivity to the decay B+ to J/psi K+, taking into account the
fragmentation ratios f_u/f_s(d). The combined results exclude branching ratios
of BR(B_s to mu+ mu-) > 1.5x10-7 and BR(B_d to mu+ mu- > 4.0x10-8 at 95%
confidence level. These are the most stringent limits on these decays at the
present time.


title:
On the nature of new baryon state X(2000) observed in the experiments
  with the SPHINX spectrometer

abstract:
  In the experiment with the SPHINX spectrometer in 1995-99 a new baryon state
X(2000) -> Sigma^0K^+ was observed in the proton diffractive reactions p + N(C)
-> Sigma^0K^+ + N(C). The main parameters of X(2000)^+ baryon are M = 1986 +- 6
MeV, Gamma = 98 +- 21 MeV. Unusual features of massive X(2000) state (narrow
decay width Gamma/M simeq 0.05, anomalously large branching ratio with strange
particle emission) make it serious candidate for cryptoexotic pentaquark baryon
with hidden strangeness. New data on the SPHINX with by an order of magnitude
enlarge statistics are in agreement with previous data and are supported our
conclusions. We propose further studies X(2000) baryon production in the meson
reactions with baryon exchange: pi^{+-} + p -> X(2000)^+ + pi^{+-} OZI -
forbidden suppressed reaction for the state |qqqsbar{s}>) and K^{+-} + p ->
X(2000)^+ + K^{+-} (OZI - allowed reaction). If the value of R=BR[pi^{+-} + p
-> X(2000)^+ + pi^{+-}]/BR[K^{+-}+p -> X(2000)^+ + K^{+-}]<<1 it will be the
crucial argument in favor of X(2000)= |qqqsbar{s}>) structure. These
experiments may be done on IHEP separated kaon beam with OKA spectrometer.


title: Measurement of the mass and width of the W boson

abstract:
  The mass and width of the W boson are measured using e+e- -> W+W- events from
the data sample collected by the OPAL experiment at LEP at centre-of-mass
energies between 170 GeV and 209 GeV. The mass (mw) and width (gw) are
determined using direct reconstruction of the kinematics of W+W- -> qqbarlv and
W+W- -> qqbarqqbar events. When combined with previous OPAL measurements using
W+W- -> lvlv events and the dependence on mw of the WW production cross-section
at threshold, the results are determined to be mw = 80.415 +- 0.042 +- 0.030 +-
0.009 GeV gw = 1.996 +- 0.096 +- 0.102 +- 0.003 GeV where the first error is
statistical, the second systematic and the third due to uncertainties in the
value of the LEP beam energy. By measuring mw with several different jet
algorithms in the qqbarqqbar channel, a limit is also obtained on possible
final-state interactions due to colour reconnection effects in W+W- ->
qqbarqqbar events. The consistency of the results for the W mass and width with
those inferred from other electroweak parameters provides an important test of
the Standard Model of electroweak interactions


title:
ATLAS sensitivity to top quark and W boson polarization in $t\bar{t}$
  events

abstract:
  Stringent tests on top quark production and decay mechanisms are provided by
the measurement of the top quark and W boson polarization. This paper presents
a detailed study of these two measurements with the ATLAS detector, in the
semileptonic (ttbar -> W W b bbar -> l nu j1 j2 b bbar) and dileptonic (ttbar
-> W W b bbar -> l nu l nu b bbar) ttbar channels. It is based on leading-order
Monte Carlo generators and on a fast simulation of the detector. A particular
attention is paid to the systematic uncertainties, which dominate the
statistical errors after one LHC year at low luminosity (10 fb^{-1}), and to
the background estimate. Combining results from both channel studies, the
longitudinal component of the W polarization (F\_0) can be measured with a 2%
accuracy and the right-handed component (F\_R) with a 1% precision with 10
fb^{-1}. Even though the top quarks in ttbar pairs are not polarized, a large
asymmetry is expected within the Standard Model in the like-spin versus
unlike-spin pair production. A 4% precision on this asymmetry measurement is
possible with 10 fb^{-1}, after combining results from both channel studies.
These promising results are converted in a sensitivity to new physics, such as
tWb anomalous couplings, top decay to charged Higgs boson, or new s-channels
(heavy resonance, gravitons) in ttbar production.


title: Colour reconnection in e+e- -> W+W- at sqrt(s) = 189 - 209 GeV

abstract:
  The effects of the final state interaction phenomenon known as colour
reconnection are investigated at centre-of-mass energies in the range sqrt(s) ~
189-209 GeV using the OPAL detector at LEP. Colour reconnection is expected to
affect observables based on charged particles in hadronic decays of W+W-.
Measurements of inclusive charged particle multiplicities, and of their angular
distribution with respect to the four jet axes of the events, are used to test
models of colour reconnection. The data are found to exclude extreme scenarios
of the Sjostrand-Khoze Type I (SK-I) model and are compatible with other
models, both with and without colour reconnection effects. In the context of
the SK-I model, the best agreement with data is obtained for a reconnection
probability of 37%. Assuming no colour reconnection, the charged particle
multiplicity in hadronically decaying W bosons is measured to be (nqqch) =
19.38+-0.05(stat.)+-0.08 (syst.).


title:
Search for Direct CP Violation in Three-Body Charmless B+- =>
  K+-pi+-pi-+ Decay

abstract:
  We report results on studies of CP violation in the three-body charmless
decay B+- => K+-pi+-pi-+. Evidence at the 3.9sigma level for large direct CP
violation in B+- => rho(770)0K+-$ is found. This is the first evidence for CP
violation in a charged meson decay. The analysis is performed using Dalitz
analysis technique with a data sample that contains 386 million BBbar pairs
collected near the Y(4S) resonance, with the Belle detector operating at the
KEKB asymmetric energy e+ e- collider.


title: Uncertainties on $W$ and $Z$ production at the LHC

abstract:
  Uncertainties on low-$x$ PDFs are crucial for the standard model benchmark
processes of $W$ and $Z$ production at the LHC. The current level of PDF
uncertainty is critically reviewed and the possibility of reducing this
uncertainty using early LHC data is investigated taking into account realistic
expectations for measurement accuracy, kinematic cuts and backgrounds.


title: Study of $B^0 \to \eta K^+ \pi^-$ and $\eta \pi^+ \pi^-$

abstract:
  We report results of studies of inclusive $B \to \eta K^+ \pi^-$ and $B \to
\eta \pi^+ \pi^-$ decays. Charged conjugates are implied throughout this paper.
These are obtained from a data sample containing 386 million $B\bar{B}$ pairs,
collected at the $\Upsilon(4S)$ resonance, with the Belle detector at the KEKB
asymmetric energy $e^+ e^-$ collider. The branching fraction of inclusive $B^0
\to \eta K^+\pi^-$ and $B^0 \to \eta \pi^+\pi^-$ are measured to be $\mathcal
B$($B^0 \to \eta K^+ \pi^-$)= $(31.7\pm1.9 ^{+2.2}_{-2.6})\times 10^{-6}$ and
$\mathcal B$($B^0 \to \eta \pi^+ \pi^-$)=$(6.2^{+1.8 + 0.8}_{-1.6 - 0.6})\times
10^{-6}$, where the first error is statistical and the second systematic. The
decays $B^0\to a_0^- X^+$, where $X^+$= $K^+$, $\pi^+$ were searched for and no
significant signals found. Upper limits of $\mathcal B$($B^0 \to a_0^-
K^+$)$<1.6 \times 10^{-6}$ and $\mathcal B$($B^0 \to a_0^- \pi^+$)$< 2.8 \times
10^{-6}$ at 90% C.L. are obtained. Here the notation $B(B^0 \to a_0^- X^+)$
indicates the product of branching fractions for $B^0 \to a_0^- X^+$ and $a_0^-
\to \eta \pi^-$.

  WIMPs and axions are the two best motivated candidates to compose the Dark
Matter of the Universe. An important number of experimental groups are
developing and using different techniques for their direct detection. An
updated review of current searches is done, emphasizing latest results


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

abstract:
  The NEMO 3 detector has been running since February 2003 with several double
beta emitters. New results are given for Mo100, Se82, Nd150, Zr96, Ca48. The
NEMO 3 detector properties are presented for tracking reconstruction,
identification of particles, energy measurement. Angular distributions for one
and two electrons are produced as well as energy spectra. It is deduced new
values of half lives for the double beta emitters and stronger limits on the
effective neutrino mass using data on Mo100 and Se82.


title: Electro-Weak Penguin and Leptonic Decays in BaBar

abstract:
  Electro-weak penguin and leptonic decays provide an indirect probe for
physics beyond the Standard Model and contribute to the determination of
Standard Model parameters. Copious quantities of B mesons produced at the
B-Factories permit precision measurements of the electro-weak penguin decays
and searches for leptonic decays. We review the current experimental status of
b -> s(d) gamma, B^0 -> D^{*0} gamma, b -> s l^+ l^- and finally B->tau nu
decays at BaBar.


title: Current Topics in D0 B Physics

abstract:
  An overview of selected topics in DO B-Physics is presented, covering
relevant detector characteristics, and with emphasis on the most recent results
in the Bs, FCNC and rare decay programs.


title: Precision Electroweak Measurements on the Z Resonance

abstract:
  We report on the final electroweak measurements performed with data taken at
the Z resonance by the experiments operating at the electron-positron colliders
SLC and LEP. The data consist of 17 million Z decays accumulated by the ALEPH,
DELPHI, L3 and OPAL experiments at LEP, and 600 thousand Z decays by the SLD
experiment using a polarised beam at SLC. The measurements include
cross-sections, forward-backward asymmetries and polarised asymmetries. The
mass and width of the Z boson, $\MZ$ and $\GZ$, and its couplings to fermions,
for example the $\rho$ parameter and the effective electroweak mixing angle,
are precisely measured. The number of light neutrino species is determined to
be 2.9840+/-0.0082. The results are compared to the predictions of the Standard
Model. Electroweak radiative corrections beyond the running of the QED and QCD
coupling constants are observed with a significance of five standard
deviations, and in agreement with the Standard Model. Of the many Z-pole
measurements, the forward-backward asymmetry in b-quark production shows the
largest difference with respect to its Standard Model expectation, at the level
of 2.8 standard deviations. Through radiative corrections evaluated in the
framework of the Standard Model, the masses of the top quark and the W Boson
are predicted. These indirect constraints are compared to the direct
measurements, providing a stringent test of the Standard Model. Using in
addition the direct measurements of $\Mt$ and $\MW$, the mass of the as yet
unobserved Standard Model Higgs boson is predicted.


title: Prospects for Measuring B_s->mu mu with the CMS Detector

abstract:
  The flavor-changing neutral current decay B_s->mu mu is highly suppressed in
the standard model, but its branching fraction of 3.4*10^-9 could be
significantly enhanced through contributions from new physics. At the LHC, this
rare decay could be observed for the first time. In this contribution, the
prospects for measuring B_s->mu mu with the CMS detector are presented. In
particular, some aspects of the experimental setup, the first and high level
trigger selections, and the offline analysis are discussed.


title:
Precise Measurement of Neutrino and Anti-neutrino Differential Cross
  Sections

abstract:
  The NuTeV experiment at Fermilab has obtained a unique high statistics sample
of neutrino and anti-neutrino interactions using its high-energy sign-selected
beam. We present a measurement of the differential cross section for
charged-current neutrino and anti-neutrino scattering from iron. Structure
functions, F_2(x,Q^2) and xF_3(x,Q^2), are determined by fitting the
inelasticity, y, dependence of the cross sections. This measurement has
significantly improved systematic precision as a consequence of more precise
understanding of hadron and muon energy scales.


title: Decay of the psi(3770) to Light Hadrons

abstract:
  We describe a search for psi(3770) decay to two-body non-DDbar final states
in e+e- data produced by the CESR collider and analyzed with the CLEO-c
detector.
  Vector-pseudoscalar production of Rho0Pi0, Rho+Pi-, OmegaPi0, PhiPi0, RhoEta,
OmegaEta, PhiEta, RhoEtaPrime, OmegaEtaPrime, PhiEtaPrime, Kstar0 K0bar, and
Kstar+K- is studied along with that of BOnePi (BOne0Pi0 and BOne+Pi-) and
Pi+Pi-Pi0.
  A statistically significant signal is found for PhiEta, at an excess cross
section of (2.4 +- 0.6) pb [Gamma_{PhiEta} (psi(3770)) =(74 +- 16)Mev], and a
suggestive suppression of Pi+Pi-Pi0 and RhoPi. We conclude with form factor
determinations for OmegaPi0, RhoEta, and RhoEtaPrime.


title: Experimental Review on Pentaquarks

abstract:
  The experimental evidence for pentaquarks is reviewed and compared with the
experiments that do not see any sign of pentaquarks.


title: Hadronic Mass Moments in B -> X_c l nu Decays

abstract:
  We report measurements of the first and second moments of the hadronic
invariant mass squared distribution, <M^2_X> and <(M^2_X-<M^2_X>)^2>, in B ->
X_c l nu decays for minimum lepton momenta ranging from 0.7 to 1.5 GeV/c in the
B meson rest frame. The measurement uses BBbar events in which the hadronic
decay of one B meson is fully reconstructed and the semileptonic decay of the
other B is inferred from the presence of an identified lepton. These results
are obtained from a 140 fb^-1 data sample collected near the Y(4S) resonance
with the Belle detector at the KEKB asymmetric energy e^+e^- collider.


title:
Search for Lepton Flavor Violating tau- Decays Including with a K0s
  Meson

abstract:
  We have searched for the tau lepton flavor violating decays tau- -> l-K0s (l
= e or mu), using a data sample of 281 fb^-1 collected with the Belle detector
at the KEKB e+e- asymmetric-energy collider. No evidence for a signal was found
in either of the decay modes, and we set the following upper limits for the
branching fractions: B(tau- -> e-K0s) < 5.6 * 10^-8 and B(tau- -> m^-K0s) < 4.9
* 10^-8 at the 90% confidence level. These results are improvements by factors
of 16 and 19, respectively, compared with previously published limits from
CLEO.


title:
Direct Search for Dirac Magnetic Monopoles in p-pbar Collisions at
  sqrt(s) = 1.96 TeV

abstract:
  We search for pair-produced Dirac magnetic monopoles in 35.7 pb^-1 of
proton-antiproton collisions at sqrt(s) = 1.96 TeV with the Collider Detector
at Fermilab (CDF). We find no monopole candidates corresponding to a 95%
confidence-level cross-section limit sigma < 0.2 pb for a monopole with mass
between 200 and 700 GeV/c^2. Assuming a Drell-Yan pair production mechanism, we
set a mass limit m>360 GeV/c^2.


title: Study of B -> eta' h

abstract:
  We report improved measurements of exclusive two-body charmless hadronic B
meson decays B -> eta' h, where h is a charged kaon or pion or a K^0. These
results are obtained from a data sample that contains 386 million B Bbar pairs
collected at the Upsilon(4S) resonance, with the Belle detector at the KEKB
asymmetric energy e+ e- collider. We measure BF(B^0 ->eta' K^0) = (56.6
^{+3.6}_{-3.5} +- 3.3) x 10^-6, BF(B^+ -> eta' K^+) = (68.6 +- 2.1 +- 3.6) x
10^-6 and BF(B^+ -> eta' pi^+) = (1.73 ^{+0.69}_{-0.63} +- 0.12) x 10^-6, where
the first and second errors are statistic and systematic, respectively. The CP
asymmetries in the charged modes are measured and no evidence for direct CP
violation is found. We measure ACP(B -> eta' K^+) = 0.03 +- 0.03 +- 0.02 and
ACP(B -> eta' pi^+) = 0.15 ^{+0.39}_{-0.38} ^{+0.02}_{-0.06}.


title:
Measurements of the Dalitz Plot Parameters for
  $K^{\pm}\to\pi^{\pm}\pi^0\pi^0$ Decays

abstract:
  The $g$, $h$, and $k$ Dalitz plot parameters, which are coefficients in a
series expansion of the squared module of the matrix element $|M(u,v)|^{2}
\propto 1 + gu + hu^{2} + kv^{2}$ ($u$, $v$ are invariant variables), have been
measured for $K^{\pm}\to \pi^{\pm} \pi^{0} \pi^{0}$ decays using $35 GeV/c$
hadron beams at the IHEP (Protvino) accelerator. Dependences of parameters and
fit quality on the $\pi^0\pi^0$ mass cut were investigated. The results point
to the important role of $\pi^+\pi^- \to \pi^0\pi^0$ charge exchange scattering
near the $\pi^0\pi^0$ mass threshold. The comparison of our data with previous
measurements is presented.


title: High Energy Photoproduction

abstract:
  The experimental and phenomenological status of high energy photoproduction
is reviewed. Topics covered include the structure of the photon, production of
jets, heavy flavours and prompt photons, rapidity gaps, energy flow and
underlying events. The results are placed in the context of the current
understanding of QCD, with particular application to present and future hadron
and lepton colliders.

  This report documents the physics case for building a 2 MW, 8 GeV
superconducting linac proton driver at Fermilab.


title: Study of Charmonium Decays into Baryon-Antibaryon Pairs

abstract:
  We study the baryonic charmonium decays of $B$ mesons, $B^+ \to \eta_c K^+$
and $B^+ \to J/\psi K^+$, where $\eta_c$ and $J/\psi$ subsequently decay into a
$p\bar p$ or $\Lambda\bar\Lambda$ pair. The charmonium produced in the above
$B$ meson decays is fully polarized. The polar angular distributions of the
baryon-antibaryon pairs are presented, along with fit results to a $1 +
\alpha_B\cos^2\theta$ parametrization. Comparisons are made with the results
from $e^+e^- \to J/\psi$ formation experiments. We also report the
firstobservation of $\eta_c \to \Lambda\bar\Lambdar$. The measured branching
fraction is ${\mathcal B}(\eta_c \to \Lambda\bar\Lambda) =
(0.87^{+0.24}_{-0.21} \pm 0.14 \pm 0.27) \times 10^{-3}$. This study is based
on a $357~fb^{-1}$ data sample recorded on the $\Upsilon({\rm 4S})$ resonance
with the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider.


title: Mice: The International Muon Ionisation Cooling Experiment

abstract:
  Muon storage rings have been proposed for use as sources of intense
high-energy neutrino beams and as the basis for muon colliders. Phase-space
compression (cooling) of the muon beam prior to acceleration and storage is
needed to optimise performance and cost. Traditional techniques cannot be
employed to cool the beam because of decay during the short muon lifetime.
Ionisation cooling, a process in which the muon beam is passed through an
alternating series of liquid-hydrogen absorbers and accelerating RF-cavities,
is the technique proposed to cool the muon beam. An international collaboration
has been formed to carry out the Muon Ionisation Cooling Experiment (MICE), and
its proposal to Rutherford Appleton Laboratory (RAL) has been approved. The
status of the MICE cooling channel, the instrumentation, and the implementation
at RAL are described, together with the predicted performance of the channel
and the measurements that will be made.


title: Recent measurements of sin2b at BaBar

abstract:
  The angle beta is the most accurately measured quantity that determines the
Unitarity Triangle. In this article I review the various measurements of this
angle performed by the BaBar Collaboration, and discuss their implications in
the search for new physics.


title: Review of Solar and Reactor Neutrinos

abstract:
  Over the last several years, experiments have conclusively demonstrated that
neutrinos are massive and that they mix. There is now direct evidence for
$\nu_e$s from the Sun transforming into other active flavors while en route to
the Earth. The disappearance of reactor $\bar{\nu}_e$s, predicted under the
assumption of neutrino oscillation, has also been observed. In this paper,
recent results from solar and reactor neutrino experiments and their
implications are reviewed. In addition, some of the future experimental
endeavors in solar and reactor neutrinos are presented.


title:
A Weekly Pattern from Hourly Estimates of the Super-Kamiokande-I
  Neutrino Flux 1996-2001

abstract:
  A search for a neutrino flux difference between weekdays and weekend days,
for the average week of the Super-Kamiokande-I (SK-I) Experiment, was
undertaken using the 5-day period version of the SK-I data taken from May 31st,
1996 to July 15th, 2001. A significant (p << 0.001) difference was found and
the most obvious neutrino flux change from weekdays to weekend days can be
summarized as follows: "Some neutrinos took the weekend off, especially on
Saturday".


title:
A Study of \bar{p}p -> Two Neutral Pseudoscalar Mesons at the
  chi_c0(1^3P_0) Formation Energy

abstract:
  Fermilab experiment E835 has studied reactions \bar{p}p -> pi0 pi0, pi0 eta,
eta eta, pi0 eta' and eta eta' in the energy region of the chi_c0(1^3P_0) from
3340 MeV to 3470 MeV. Interference between resonant and continuum production is
observed in the pi0 pi0 and eta eta channels, and the product of the input and
output branching fractions is measured. Limits on resonant production are set
for the pi0 eta and pi0 eta' channels. An indication of interference is
observed in the eta eta' channel. The technique for extracting resonance
parameters in an environment dominated by continuum production is described.


title: A Non-parametric Approach to the D+ to K*0bar mu+ nu Form Factors

abstract:
  Using a large sample of D+ -> K- pi+ mu+ nu decays collected by the FOCUS
photoproduction experiment at Fermilab, we present the first measurements of
the helicity basis form factors free from the assumption of spectroscopic pole
dominance. We also present the first information on the form factor that
controls the s-wave interference discussed in a previous paper by the FOCUS
collaboration. We find reasonable agreement with the usual assumption of
spectroscopic pole dominance and measured form factor ratios.


title: Recent Results of $\psi(2S)$ Decays from BES

abstract:
  Results of many $\psi(2S)$ hadronic decays and the results of $\psi(2S)$
radiative/hadronic transitions from BES collaboration in the past year are
presented. Measurement of $\BR(\jpsi\ra K^0_S K^0_L)$ and the preliminary
result of searching for the decay $\psi(3770)\ra\rho\pi$ are also reported.


title: Signal Processing in the PVLAS Experiment

abstract:
  Nonlinear interactions of light with light are well known in quantum
electronics, and it is quite common to generate harmonic or subharmonic beams
from a primary laser with photonic crystals. One suprising result of quantum
electrodynamics is that because of the quantum fluctuations of charged fields,
the same can happen in vacuum. The virtual charged particle pairs can be
polarized by an external field and vacuum can thus become birefringent: the
PVLAS experiment was originally meant to explore this strange quantum regime
with optical methods. Since its inception PVLAS has found a new, additional
goal: in fact vacuum can become a dichroic medium if we assume that it is
filled with light neutral particles that couple to two photons, and thus PVLAS
can search for exotic particles as well. PVLAS implements a complex signal
processing scheme: here we describe the double data acquisition chain and the
data analysis methods used to process the experimental data.


title: First Observation of psi(3770) --> gamma chi_{c1} --> gamma gamma J/psi

abstract:
  From e+e- collision data acquired with the CLEO detector at CESR, we observe
the non-D Dbar decay psi(3770)->gamma chi_c1 with a statistical significance of
6.6 standard deviations, using the two-photon cascades to J/psi and
J/psi->l+l-. We determine sigma(e+e- -> psi(3770)) x BR(psi(3770)->gamma
chi_c1) =(18.0 pm3.3 pm2.5) pb and branching fraction BR(psi(3770)->gamma
chi_c1)=(2.8+-0.5+-0.4) x 10^-3. We set 90% C.L. upper limits for the
transition to chi_c2 (chi_c0) : sigma x BR < 5.7 pb (< 282 pb) and BR < 0.9 x
10^-3 (<44 x 10^-3). We also determine Gamma(psi(3770)->gamma
chi_c1)/Gamma(psi(3770)->pi+pi-J/psi) =1.5+-0.3+-0.3 (>1.0 at 90 % C.L.), which
bears upon the interpretation of X(3872).

title:
Search for the Cryptoexotic Member of the Baryon Antidecuplet 1/2+ in
  the Reactions pi- p --> pi- p and pi- p --> K L

abstract:
  The main goal of this proposal is the search for a narrow cryptoexotic
nucleon resonance by scanning of the pi- p system invariant mass in the region
(1610-1770) MeV with the detection of pi- p and K Lambda decays. The scan is
supposed to be done by the variation of the incident pi- momentum and its
measurement with the accuracy of up to +-0.1% (better than 1 MeV in terms of
the invariant mass in the whole energy range) with a set of proportional
chambers located in the first focus of the magnetooptical channel. High
sensitivity of the method to the resonance under search is shown. The secondary
particles scattered from a liquid hydrogen target are detected by sets of the
wire drift chambers equipped with modern electronics. The time scale of the
project is about 3 years. The budget estimate including manpower, the apparatus
and operation cost, is about 40 million rubles. The beam time required is (4-6)
two week runs on "high" (10 GeV/c) flattop of the ITEP proton synchrotron.


title:
Further study of narrow baryon resonance decaying into $K^0_s p$ in
  $pA$-interactions at $70 GeV/c$ with SVD-2 setup

abstract:
  The inclusive reaction $p A \to pK^0_s + X$ was studied at IHEP accelerator
with $70 GeV$ proton beam using SVD-2 detector. Two different samples of
$K^0_s$, statistically independent and belonging to different phase space
regions were used in the analyses and a narrow baryon resonance with the mass
$M=1523\pm 2(stat.)\pm 3(syst.) MeV/c^2$ was observed in both samples of the
data. The statistical significance was estimated to be of $8.0 \sigma$ (392
signal over 1990 background events). Using the part of events reconstructed
with better accuracy the width of resonance was estimated to be $\Gamma < 14
MeV/c^2$ at 95% C.L.


title: Recent Results on J/\psi Decays from BESII

abstract:
  The new observation of X(1835)is reported using 58 million $\jpsi$ events
collected at BES II detector. We also present the measurements of J/\Psi and
eta_c decays, of them some are the first measurements and some improve the
precision in previous measurements.


title: Future Hadron Physics at Fermilab

abstract:
  Today, hadron physics research occurs at Fermilab as parts of broader
experimental programs. This is very likely to be the case in the future. Thus,
much of this presentation focuses on our vision of that future - a future aimed
at making Fermilab the host laboratory for the International Linear Collider
(ILC). Given the uncertainties associated with the ILC - the level of needed
R&D, the ILC costs, and the timing - Fermilab is also preparing for other
program choices. I will describe these latter efforts, efforts focused on a
Proton Driver to increase the numbers of protons available for experiments. As
examples of the hadron physics which will be coming from Fermilab, I summarize
three experiments: MIPP/E907 which is running currently, and MINER A and
Drell-Yan/E906 which are scheduled for future running periods. Hadron physics
coming from the Tevatron Collider program will be summarized by Arthur Maciel
in another talk at Hadron05.


title:
Measurement of Branching Fractions and Resonance Contributions for B0 ->
  D0bar K+ pi- and Search for B0 -> D0 K+ pi- Decays

abstract:
  Using 226 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 branching fraction for $B^0\to \bar{D}^0 K^+\pi^-$,
excluding $B^0\to D^{*-} K^+$ to be $ {\cal B}(B^0\to \bar{D}^0 K^+\pi^-) = (88
\pm 15 \pm 9)\times 10^{-6} . $ We observe $B^0\to \bar{D}^0 K^*(892)^0$ and
$B^0\to D_2^*(2460)^- K^+$ contributions. The ratio of branching fractions
${\cal B}(B^0\to D^{*-}K^+)/{\cal B}(B^0\to D^{*-}\pi^+) = (7.76\pm 0.34 \pm
0.29)%$ is measured separately. The branching fraction for the suppressed mode
$B^0\to D^0 K^+\pi^-$ is $ {\cal B}(B^0\to D^0 K^+\pi^-) < 19 \times 10^{-6} $
at the 90% confidence level.


title: Search for New Physics at Colliders

abstract:
  In this paper I present the most recent results of the ongoing searches,
mainly from Tevatron Collider experiments, for new physics beyond the Standard
Model. While no signal has been seen so far, many analyses are reaching the
point in which either a discovery will take place or strong limit on currently
popular theories will be set.


title:
The Microcalorimeter Arrays for a Rhenium Experiment (MARE): a
  next-generation calorimetric neutrino mass experiment

abstract:
  Neutrino oscillation experiments have proved that neutrinos are massive
particles, but can't determine their absolute mass scale. Therefore the
neutrino mass is still an open question in elementary particle physics. An
international collaboration is growing around the project of Microcalorimeter
Arrays for a Rhenium Experiment (MARE) for directly measuring the neutrino mass
with a sensitivity of about 0.2eV/c2. Many groups are joining their experiences
and technical expertise in a common effort towards this challenging experiment.
We discuss the different scenarios and the impact of MARE as a complement of
KATRIN.


title: New Hadron Spectroscopy with BABAR

abstract:
  We review hadron spectroscopy at BABAR with emphasis on recent results from
the studies of the X(3872) state, inclusive charmonia on recoil, double
charmonium production, and the broad structure observed at around 4.26 GeV/c^2.
These results are preliminary, unless otherwise specified.


title:
Measurement of the Inclusive Electron Spectrum in Charmless Semileptonic
  B Decays Near the Kinematic Endpoint and Determination of |Vub|

abstract:
  We present a measurement of the inclusive electron spectrum in charmless
semileptonic B decays near the kinematic limit for B->X_c e\nu transitions,
using a sample of 88 million Upsilon(4S) decays recorded by the BABAR detector.
Partial branching fraction measurements are performed in five overlapping
intervals of the electron momentum. For the interval of 2.0-2.6 GeV/c we obtain
\Delta Br(B->X_u e\nu) = (0.572+-0.041(stat)+-0.065(syst))x10^{-3}. Combining
this result with shape function parameters extracted from BABAR measurements of
moments of the inclusive photon spectrum in B->X_s+gamma decays and moments of
the hadron mass and lepton energy spectra in B->X_c l\nu decays we determine
|V_{ub}|=((4.44+-0.25(exp) ^{+0.42}_{-0.38}(SF)+-0.22(theory))x10^{-3}. Here
the first error represents the combined statistical and systematic experimental
uncertainties of the partial branching fraction measurement, the second error
refers to the uncertainty of the determination of the shape function
parameters, and the third error is due to theoretical uncertainties in the QCD
calculations.


title: Daya Bay Neutrino Experiment

abstract:
  The Daya Bay Neutrino Experiment is proposed to measure sin^2(2\theta_{13})
to better than 0.01 at 90% C.L. in a three-year run. The experimental site,
detector design, and background estimation are presented.


title:
Study of the decay asymmetry parameter and CP violation parameter in the
  Lambdac+ --> Lambda pi+ decay

abstract:
  Using data from the FOCUS (E831) experiment at Fermilab, we present a new
measurement of the weak decay-asymmetry parameter alpha(Lambdac) in Lambdac -->
Lambda pi decay. Comparing particle with antiparticle decays, we obtain the
first measurement of the CP violation parameter : A =
[alpha(Lambdac)+alpha(antiLambda_c)]/[alpha(Lambdac)-alpha(antiLambda_c)]. We
obtain alpha(Lambdac)=-0.78+-0.16+-0.13 and A = -0.07+-0.19+-0.12 where errors
are statistical and systematic.


title: Top Properties and Rare Decays from the Tevatron

abstract:
  The top quark is the most recently discovered quark. Relatively little is
known about its properties so far. Due to its very large mass of about $175 \rm
GeV/c^2$, the top quark behaves differently from all other quarks and provides
a unique environment for tests of the Standard Model. Furthermore, it is
believed to yield sensitivity to physics beyond the Standard Model. This report
discusses the latest measurements and studies of top quark properties and rare
decays from the Tevatron in Run II.


title: Physics from Polarized ep Collisions at HERA

abstract:
  Physics from the polarized electron or positron beam colliding with the
unpolarized proton beam at HERA-II as well as from the unpolarized ep
collisions at HERA-I is discussed. Results shown include (i) inclusive neutral
and charged current cross sections and structure functions measurements at
HERA-I, (ii) the impact of these measurements on parton density functions, on
electroweak parameters and searches for new physics and (iii) the first results
at HERA-II and its future prospects.


title:
Measurement of the Absolute Branching Ratio for the K+ -> mu+ nu(gamma)
  Decay with the KLOE Detector

abstract:
  We have measured the fully inclusive K+ -> mu+nu(gamma) absolute branching
ratio with the KLOE experiment at DAFNE, the Frascati Phi-factory. From some
865,283 K+ -> mu+nu(gamma) decays obtained from a sample of about 5.2x10^8
Phi-meson decays, we find BR(K+ -> mu+ nu (gamma)) = 0.6366 +-0.0009(stat.)
+-0.0015(syst.), corresponding to an overall fractional error of 0.27%. Using
recent lattice results on the decay constants of pseudoscalar mesons one can
obtain an estimate for the CKM mixing matrix element |Vus|=0.2223+-0.0026.


title: Search for Exclusive Multi-Body Non-DbarD Decays at the psi(3770)

abstract:
  Using data collected at the psi(3770) resonance with the CLEO-c detector at
the Cornell e^+e^- storage ring, we present searches for 25 charmless decay
modes of the psi(3770), mostly multibody final states. No evidence for
charmless decays is found.


title: Dalitz analysis of the three-body charmless decay B0=>Kspi+pi-

abstract:
  We report preliminary results of a Dalitz plot analysis of three-body
charmless B0=>Kspi+pi- decays. The analysis is performed with a data sample
that contains 386 million $B\bar{B}$ pairs collected near the Y(4S) resonance
with the Belle detector at the KEKB asymmetric energy e+e- collider.
Measurements of branching fractions for quasi-two-body decays B0=>rho(770)0K0,
B0=>f0(980)K0, B0=>K*(892)+pi-, B0=>K*(1430)+pi-, and upper limits on several
other quasi-two-body decay modes are reported.


title: Neutrino Physics and Astrophysics : Highlights

abstract:
  This article presents an overview of neutrino physics research, with
highlights on the physics goals, results and interpretations of the current
neutrino experiments and future directions and program. It is not meant to be a
comprehensive account or detailed review article. Interested readers can pursue
the details via the listed references.


title:
Measurement of the ttbar production cross section in proton-antiproton
  collisions at sqrt{s}=1.96 TeV using multijet events

abstract:
  We present two measurements of the ttbar production cross section in
collisions of protons and antiprotons at sqrt{s}=1.96 TeV. We analyze a dataset
of 310+/-20 pb-1 collected with the CDF2 detector. In the first measurement, we
select events with six to eight jets, at least one of which having a displaced
secondary vertex, little or no missing transverse energy and optimized
kinematical criteria consistent with the ttbar all-hadronic decay channel. In
the second measurement, we select events with four or more jets, at least one
of which having a displaced secondary vertex, high missing transverse energy,
and optimized kinematical criteria consistent with the decay of ttbar to
tau+jets. The averaged ttbar production cross section, determined from six
different measurements using the CDF2 detector in the dilepton, lepton+jets and
all-hadronic decay channels, is also calculated to be sigma_ttbar=7.1+/-0.6
(stat)+/-0.7(syst)+/-0.4 (lumi) pb, in agreement with the prediction of the
standard model.


title: Measurement of D0 -> pilnu (Klnu) and their form factors

abstract:
  Using a data sample of 282 1/fb collected by the Belle experiment at the KEKB
e+e- collider, we study D0 -> pilnu and D0 -> Klnu decays (l = mu,e) in e+e-
annihilation. We identify D* -> D0pi decays by using the mass of the system
recoiling against a fully reconstructed tag-side D* or D meson, allowing for
additional primary mesons from fragmentation.
  Using a novel global reconstruction method that provides very good resolution
in neutrino momentum and in q^2 = (p_l+p_nu)^2, we reconstructed D0 -> pilnu
and D0 -> Klnu decays. From these events we measured the branching fraction
ratios BR(D0 -> pienu)/BR(D0 -> Kenu) = 0.0809 +- 0.0080 +- 0.0032$ and BR(D0
-> pimunu)/BR(D0 -> Kmunu) = 0.0677 +- 0.0078 +- 0.0047, and the semileptonic
form factor ratio f+(D0 -> pilnu})^2/f+(D0 -> Klnu})^2|Vcd|^2/|Vcs|^2|_{q^2=0}
= 0.041 +- 0.003 +- 0.004, where the errors are statistical and systematic,
respectively.


title: Pion scattering lengths from NA48

abstract:
  The anomaly (cusp) in the mass spectrum of two neutral pions from the
three-pion decays of charged kaon has been observed in the NA48/2 experiment.
Using the recently developed interpretation of this effect in terms of Chiral
Perturbative Theory, the pion scattering parameters are measured. The
preliminary result for the pion scattering length difference, based on the part
of statistics, is (a0-a2)m(pi+) = 0.281 +/- 0.007 (stat) +/- 0.014(syst) +/-
0.014(extern).


title:
Precision Measurements of the Timelike Electromagnetic Form Factors of
  Pion, Kaon, and Proton

abstract:
  Using 20.7 pb^-1 of e+e- annihilation data taken at sqrt{s} = 3.671 GeV with
the CLEO-c detector, precision measurements of the electromagnetic form factors
of the charged pion, charged kaon, and proton have been made for timelike
momentum transfer of |Q^2| = 13.48 GeV^2 by the reaction e+e- to h+h-. The
measurements are the first ever with identified pions and kaons of |Q^2| > 4
GeV^2, with the results F_pi(13.48 GeV^2) = 0.075+-0.008(stat)+-0.005(syst) and
F_K(13.48 GeV^2) = 0.063+-0.004(stat)+-0.001(syst). The result for the proton,
assuming G^p_E = G^p_M, is G^p_M(13.48 GeV^2) =
0.014+-0.002(stat)+-0.001(syst), which is in agreement with earlier results.


title:
Observation of narrow baryon resonance in $pK^0_s$ mode in
  $pA$-interactions at $70 GeV/c$ with SVD-2 setup

abstract:
  We report on the SVD-2 experiment data analysis aimed to search for an exotic
baryon state, the $\Theta^+$-baryon, in a $pK^0_s$ decay mode with IHEP U-70
accelerator proton beam at $70 GeV/c$. A resonant structure with
$M=1526\pm3(stat.)\pm 3(syst.)~MeV/c^2$ and $\Gamma < 24 MeV/c^2$ was found in
the $pK^0_s$ invariant mass spectrum, with the statistical significance of this
peak estimated as $5.6~\sigma$.


title: Top Mass Measurements at the Tevatron Run II

abstract:
  The latest top quark mass measurements by the CDF and D\O~ experiments are
presented here. The mass has been determined in the dilepton ($\ttbar \to
e\mu,ee,\mu\mu$ + jets +$\met$) and lepton plus jets ($\ttbar \to e$ or $\mu$ +
jets +$\met$) final states. The most accurate single result from lepton plus
jets channel is 173.5$^{+3.7}_{-3.6}$(stat. + Jet Energy Scale
Systematic)$\pm1.3$(syst.) ~GeV/c$^{2}$, which is better than the combined CDF
and D\O~ Run~I average. A preliminary and unofficial average of the best
experimental Run~II results gives $M_{top}$ = $172.7\pm3.5$ GeV/c${^2}$.


title:
A measurement of the CP-conserving component of the decay KS -> pi+ pi-
  pi0

abstract:
  The NA48 collaboration has measured the amplitude of the CP-conserving
component of the decay KS --> pi+ pi- pi0 relative to KL --> pi+ pi- pi0. For
the characteristic parameter lambda, the values Re(lambda) = 0.038 +/-0.010 and
Im(lambda) = -0.013 +/- 0.007 have been extracted. These values agree with
earlier measurements and with theoretical predictions from chiral perturbation
theory.


title:
Inclusive production of charged pions in p+p collisions at 158 GeV/c
  beam momentum

abstract:
  New results on the production of charged pions in p+p interactions are
presented. The data come from a sample of 4.8 million inelastic events obtained
with the NA49 detector at the CERN SPS at 158 GeV/c beam momentum. Pions are
identified by energy loss measurement in a large TPC tracking system which
covers a major fraction of the production phase space. Inclusive invariant
cross sections are given on a grid of nearly 300 bins per charge over intervals
from 0 to 2 GeV/c in transverse momentum and from 0 to 0.85 in Feynman x. The
results are compared to existing data in overlapping energy ranges.


title:
Measurement of the Spin Rotation Parameter A in the Elastic Pion-proton
  Scattering at 1.43 GeV/c

abstract:
  The ITEP-PNPI collaboration presents new results of the measurements of the
spin rotation parameter A in the elastic scattering of negative pions on
protons at P_beam=1.43 GeV/c. The results are compared to the predictions of
several partial wave analyses. The experiment was performed at the ITEP proton
synchrotron, Moscow.


title:
Spin-Flavor Decomposition in Polarized Semi-Inclusive Deep Inelastic
  Scattering Experiments at Jefferson Lab

abstract:
  A Jefferson Lab experiment proposal was discussed in this talk. The
experiment is designed to measure the beam-target double-spin asymmetries
$A_{1n}^h$ in semi-inclusive deep-inelastic $\vec n({\vec e}, e^\prime \pi^+)X$
and $\vec n({\vec e}, e^\prime \pi^-)X$ reactions on a longitudinally polarized
$^3$He target. In addition to $A_{1n}^h$, the flavor non-singlet combination
$A_{1n}^{\pi^+ - \pi^-}$, in which the gluons do not contribute, will be
determined with high precision to extract $\Delta d_v(x)$ independent of the
knowledge of the fragmentation functions. The data will also impose strong
constraints on quark and gluon polarizations through a global NLO QCD fit.


title:
Spatial Resolution of Double-Sided Silicon Microstrip Detectors for the
  PAMELA Apparatus

abstract:
  The PAMELA apparatus has been assembled and it is ready to be launched in a
satellite mission to study mainly the antiparticle component of cosmic rays. In
this paper the performances obtained for the silicon microstrip detectors used
in the magnetic spectrometer are presented. This subdetector reconstructs the
curvature of a charged particle in the magnetic field produced by a permanent
magnet and consequently determines momentum and charge sign, thanks to a very
good accuracy in the position measurements (better than 3 um in the bending
coordinate). A complete simulation of the silicon microstrip detectors has been
developed in order to investigate in great detail the sensor's characteristics.
Simulated events have been then compared with data gathered from minimum
ionizing particle (MIP) beams during the last years in order to tune free
parameters of the simulation. Finally some either widely used or original
position finding algorithms, designed for such kind of detectors, have been
applied to events with different incidence angles. As a result of the analysis,
a method of impact point reconstruction can be chosen, depending on both the
particle's incidence angle and the cluster multiplicity, so as to maximize the
capability of the spectrometer in antiparticle tagging.


title:
Search for the pentaquark candidate $\Theta^+$(1540) in the hyperon beam
  experiment WA89

abstract:
  We report on a high-statistics search for the \t1540 resonance in
$\Sigma^-$-nucleus collisions at 340 \gevc1 . No evidence for this resonance
was found in our data sample which contains 13 millions $K^0_s \to \pi^+\pi^- $
decays above background. For the decay channel $\Theta^+ \to K^0_s p$ and the
kinematic range $x_F>$ 0.05 we find the production cross section to be
$BR(\Theta^+ \to K^0_s p)\cdot \sigma_0 <$ 1.8 $\mu$b per nucleon at 99% CL.


title: Sigma, Kappa, fo(980) and a0(980)

abstract:
  Both sigma and kappa are well established from E791 data on D->3pi and
Ds->Kpipi and BES II data on J/Psi -> omega pi pi and KKpipi. These fits are
accurately consistent with pipi and Kpi elastic scattering when one allows for
the Adler zero which arises from Chiral Symmetry Breaking. The phase variation
with mass is consistent between elastic scattering and production data.
Possible interpretations of sigma, kappa, fo(980) and ao(980) are explored. The
experimental ratio g^2(fo(980)->KK)/g^2(ao(980)->KK) = 2.7+-0.5 suggests
strongly that fo(980) has a large KK component in its wave function. This is a
natural consequence of its pole lying very close to the KK threshold.


title: Radiative Decays of the Upsilon(1S) to a Pair of Charged Hadrons

abstract:
  Using data obtained with the CLEO~III detector, running at the Cornell
Electron Storage Ring (CESR), we report on a new study of exclusive radiative
Upsilon(1S) decays into the final states gamma pi^+ pi^-, gamma K^+ K^-, and
gamma p pbar.. We present branching ratio measurements for the decay modes
Upsilon(1S) to gamma f_2(1270), Upsilon(1S) to gamma f_2'(1525), and
Upsilon(1S) to gamma K^+K^-; helicity production ratios for f_2(1270) and
f_2'(1525); upper limits for the decay Upsilon(1S) to gamma f_J(2200), with
f_J(2220) to pi^+ pi^-, K^+ K^-, p pbar; and an upper limit for the decay
Upsilon(1S) to gamma X(1860), with X(1860) to gamma p pbar.


title: Elastic J/Psi Production at HERA

abstract:
  Cross sections for elastic production of J/Psi mesons in photoproduction and
electroproduction are measured in electron proton collisions at HERA using an
integrated luminosity of 55 pb^{-1}. Results are presented for photon
virtualities Q^2 up to 80 GeV^2. The dependence on the photon-proton centre of
mass energy W_{gamma p} is analysed in the range 40 < \Wgp < 305 GeV in
photoproduction and 40 < \Wgp < 160 GeV in electroproduction. The \Wgp
dependences of the cross sections do not change significantly with Q^2 and can
be described by models based on perturbative QCD. Within such models, the data
show a high sensitivity to the gluon density of the proton in the domain of low
Bjorken x and low Q^2. Differential cross sections d\sigma/dt, where t is the
squared four-momentum transfer at the proton vertex, are measured in the range
|t|<1.2 GeV^2 as functions of \Wgp and Q^2. Effective Pomeron trajectories are
determined for photoproduction and electroproduction. The J/Psi production and
decay angular distributions are consistent with s-channel helicity
conservation. The ratio of the cross sections for longitudinally and
transversely polarised photons is measured as a function of Q^2 and is found to
be described by perturbative QCD based models.


title: First measurement of the omega-meson production at RHIC by PHENIX

abstract:
  The PHENIX experiment at RHIC measured the omega-meson production in the
range of pT from 2.5 GeV/c to 9.5 GeV/c in p+p and d+Au collision systems at
sqrt{s_{NN}}=200 GeV. We present the consistent results of two independent
measurements in decay channels omega-->pi^{0}pi^{+}pi^{-}$ and
omega-->pi^{0}gamma. The omega/pi^{0} ratio was found to be 0.90+/-0.06. The
Nuclear Modification Factor R_{dA} is 1.3+/-0.2 both in the Minimum Biased and
(0%-20%) central event samples. The mass of the omega-meson was measured to be
consistent with the PDG value within the errors of the measurement. We also
measured the K_{S}^{0}-meson production in K_{S}^{0}-->pi^{0}pi^{0} in the same
collision systems.


title: Very Long Baseline Neutrino Oscillations, The BNL VLBNLO Concept

abstract:
  A wide energy-band neutrino beam sent over a very long baseline to a massive
detector can break the degeneracies in the neutrino oscillation parameters. It
can measure the disappearance parameters with precision and determine the mass
hierarchy. If $\theta_{13}$ is large enough the CP violating phase can be
measured with neutrino running alone and anti-neutrino running can confirm CPV
and improve the parameter measurements. Brookhaven National Laboratory is
pursuing such an experiment.


title: The kappa in E791 data for D->K-pi-pi

abstract:
  A combined fit is made to E791 data on D->K-pi-pi, LASS data on K-pi elastic
scattering, and BES II data on J/Psi->K*(890)-K-pi.In all cases, the K-pi
S-wave is fitted well with a kappa resonance and Ko(1430); the kappa requires
an s-dependent width with an Adler zero near threshold. The pole position of
the kappa is at M - iGamma/2 = (750 +30 -55) - i(342 +- 60) MeV. The E791
collaboration fitted their data using a form factor for the production process
D->kappa-pi. It is shown that this form factor is not needed. The data require
point-like production with an RMS radius <0.38 fm with 95 percent confidence.


title:
Nuclear modification and elliptic flow measurements for $\phi$ mesons at
  $\sqrt{s_{NN}}$ = 200 GeV d+Au and Au+Au collisions by PHENIX

abstract:
  We report the first results of the nuclear modification factors and elliptic
flow of the phi mesons measured by the PHENIX experiment at RHIC in high
luminosity Au+Au collisions at sqrt(sNN) = 200 GeV. The nuclear modification
factors R_AA and R_CP of the phi follow the same trend of suppression as pi0's
in Au+Au collisions. In d+Au collisions at sqrt(sNN) = 200 GeV, the phi mesons
are not suppressed. The elliptic flow of the phi mesons, measured in the
minimum bias Au+Au events, is statistically consistent with other identified
particles.


title: Sigma, Kappa and fo(980) in E791 and BES II data

abstract:
  Both sigma and kappa are well established from E791 data on D->3pi and
D->K-pi-pi$ and BES II data on J/Psi->omega-pi-pi and KKpipi. Fits to these
data are accurately consistent with pi-pi and Kpi elastic scattering when one
allows for the Adler zero which arises from Chiral Symmetry Breaking. The phase
variation with mass is also consistent between elastic scattering and
production data.


title:
Flavour Independent Searches for Hadronically Decaying Neutral Higgs
  Bosons

abstract:
  This paper describes flavour independent searches for hadronically decaying
neutral Higgs bosons in the data collected by the DELPHI experiment at LEP, at
centre-of-mass energies between 189 and 209 GeV. The collected data-set
corresponds to an integrated luminosity of around 610 pb^{-1}. The e+e- -> hA
and e+e- -> hZ processes are considered, with direct Higgs boson decays into
hadrons. No evidence for Higgs boson production is found, and cross-section
limits are set as a function of the Higgs boson masses. No explicit assumptions
are made on the underlying physics beyond the Standard Model, allowing
interpretation of the data in a large class of models.


title:
Production of Xi_c^0 and Xi_b in Z decays and lifetime measurement of
  Xi_b

abstract:
  The charmed strange baryon Xi_c^0 was searched for in the decay channel
Xi_c^0 -> Xi- pi+, and the beauty strange baryon Xi_b in the inclusive channel
Xi_b -> Xi- l- anti-nu X, using the 3.5 million hadronic Z events collected by
the DELPHI experiment in the years 1992--1995. The Xi- was reconstructed
through the decay Xi- -> Lambda pi-, using a constrained fit method for cascade
decays. An iterative discriminant analysis was used for the Xi_c^0 and Xi_b
selection. The production rates were measured to be f_{Xi_c^0} x BR(Xi_c^0 ->
Xi- pi+)= (4.7 +/- 1.4 (stat.) +/- 1.1 (syst.))10^{-4} per hadronic Z decay,
and BR(b -> Xi_b) x BR(Xi_b -> Xi- l- X)= (3.0 +/- 1.0 (stat.) +/- 0.3
(syst.))10^{-4} for each lepton species (electron or muon). The lifetime of the
Xi_b baryon was measured to be tau_{Xi_b} = 1.45{^{+0.55}_{-0.43}} (stat.) +/-
0.13 (syst.) ps. A combination with the previous DELPHI lifetime measurement
gives tau_{Xi_b} = 1.48{^{+0.40}_{-0.31}} (stat.) +/- 0.12 (syst.) ps.


title:
Determination of heavy quark non-perturbative parameters from spectral
  moments in semileptonic B decays

abstract:
  Moments of the hadronic invariant mass and of the lepton energy spectra in
semileptonic B decays have been determined with the data recorded by the DELPHI
detector at LEP. From measurements of the inclusive b-hadron semileptonic
decays, and imposing constraints from other measurements on b- and c-quark
masses, the first three moments of the lepton energy distribution and of the
hadronic mass distribution, have been used to determine parameters which enter
into the extraction of |V_cb| from the measurement of the inclusive b-hadron
semileptonic decay width. The values obtained in the kinetic scheme are: m_b(1
GeV) = 4.591 +/- 0.062 +/- 0.039 +/- 0.005 GeV/c^2 m_c(1 GeV) = 1.170 +/- 0.093
+/- 0.055 +/- 0.005 GeV/c^2 mu_{pi}^2(1 GeV) = 0.399 +/- 0.048 +/- 0.034 +/-
0.087 GeV^2 \tilde{\rho}_D^3 = 0.053 +/- 0.017 +/- 0.011 +/- 0.026 GeV^3, and
include corrections at order 1/m_b^3. Using these results, and present
measurements of the inclusive semileptonic decay partial width of b-hadrons at
LEP, an accurate determination of |V_cb| is obtained: |V_cb| = 0.0421 x (1 +/-
0.014 (meas.) +/- 0.014 (fit) +/- 0.015 (th.)).


title: Charged Particle Multiplicity in Three-Jet Events and Two-Gluon Systems

abstract:
  The charged particle multiplicity in hadronic three-jet events from Z decays
is investigated. The topology dependence of the event multiplicity is found to
be well described by a modified leading logarithmic prediction. A parameter fit
of the prediction to the data yields a measurement of the colour factor ratio
C_A/C_F with the result C_A/C_F = 2.261 +/- 0.014 (stat.) +/- 0.036 (exp.) +/-
0.066 (theo.) in agreement with the SU(3) expectation of QCD. The quark-related
contribution to the event multiplicity is subtracted from the three-jet event
multiplicity resulting in a measurement of the multiplicity of two-gluon
colour-singlet states over a wide energy range. The ratios r=N_{gg}(s)/N_{q
qbar}(s) of the gluon and quark multiplicities and r^{(1)}=N_{gg}'(s)/N_{q
qbar}'(s) of their derivatives are compared with perturbative calculations.
While a good agreement between calculations and data is observed for r^{(1)},
larger deviations are found for r indicating that non-perturbative effects are
more important for r than for r^{(1)}.


title: The Kappa in J/Psi -> Kpplus-piminus-Kminus-piplus

abstract:
  BES II data for J/Psi->K*(890)Kpi reveal a strong kappa peak in the Kpi
S-wave near threshold. Both magnitude and phase are determined in slices of Kpi
mass by interferences with strong Ko(1430), K1(1270) and K1(1400) signals. The
phase variation with mass agrees within errors with LASS data for Kpi elastic
scattering. A combined fit is presented to both BES and LASS data. The fit uses
a Breit-Wigner amplitude with an s-dependent width containing an Adler zero.
The kappa pole is at 760+-20(stat)+-40(syst) - i(420+-45+-60syst) MeV. The
S-wave I=0 scattering length a_0 = 0.23+-0.04 (in units of m(pi)) is close to
the prediction 0.19+-0.02 of Chiral Perturbation Theory.


title: Bose Einstein correlations of neutral pion pairs at LEP

abstract:
  With the OPAL detector at LEP we measured at energies around the Z0 peak the
Bose-Einstein Correlations (BECs) of neutral pion pairs. We compare the results
of this measurement with former results obtained at LEP for hadrons including
those obtained from Fermi-Dirac Correlations (FDCs).


title: KLOE extraction of Vus from kaon decays and lifetimes

abstract:
  The most precise determination of Vus comes from semileptonic kaon decays.
The KLOE experiment at DA\PhiNE the Frascati \phi-factory, has measured all the
exeperimental inputs to Vus for both neutral and charged kaons. Preliminary
results for BR(K^\pm\to\pi^0 e^\pm\nu) and BR(K^\pm\to\pi^0 \mu^\pm\nu), and
for \tau_\pm are presented, together with measurements of the K_Le3 and K_L\mu3
decay BR, the K_Se3 decay BR and the K_L lifetime \tau_L. From our results for
the 5 braching ratios and \tau_L we find Vus=0.2258\pm0.0022. We have also
measured the fully inclusive K^+\mu2(\gamma) absolute branching ratio for which
we obtain BR(K^+\to\mu\nu(\gamma))=0.6366\pm0.0017. Combining this value with
recent lattice results for f_K/f_\pi gives Vus=0.2223\pm0.0026.


title: The SPL-Fr\'{e}jus physics potential

abstract:
  An optimization of the CERN-SPL beam line has been performed which leads to
better sensitivities to the $\theta\_{13}$ mixing angle and to the
$\delta\_{CP}$ violating phase than those advocated considering baseline
scenario.


title: Double hadron leptoproduction in the nuclear medium

abstract:
  First measurement of double-hadron production in deep-inelastic scattering
has been measured with the HERMES spectrometer at HERA using a 27.6 GeV
positron beam with deuterium, nitrogen, krypton and xenon targets. The
influence of the nuclear medium on the ratio of double-hadron to single-hadron
yields has been investigated. Nuclear effects are clearly observed but with
substantially smaller magnitude and reduced $A$-dependence compared to
previously measured single-hadron multiplicity ratios. The data are in fair
agreement with models based on partonic or pre-hadronic energy loss, while they
seem to rule out a pure absorptive treatment of the final state interactions.
Thus, the double-hadron ratio provides an additional tool for studying
modifications of hadronization in nuclear matter.


title: Deeply Virtual Compton Scattering and Prompt Photon production at HERA

abstract:
  Recent results on the Deeply Virtual Compton Scattering (DVCS) and prompt
photon productions from H1 and ZEUS experiments on the $ep$ collider HERA are
presented. A new DVCS cross section measurements of the H1 Collaboration, for
photon virtualities $Q^2>4$ GeV$^2$ and photon-proton c.m.s. energy $30<W<140$
GeV, are discussed and compared to NLO QCD calculations encoding Generalized
Parton Distributions (GPDs) and to Colour Dipole model predictions. For the
first time the cross section dependence is reported on the momentum transfer
squared at the proton vertex, $t$. Prompt photon production in deep inelastic
scattering and photoproduction are presented both in the inclusive case and in
the presence of a jet. The results are compared to NLO QCD predictions.


title: Results from PP2PP Experiment at RHIC

abstract:
  We report on the first measurement of the single spin analyzing power
($A\_N$) at $\sqrt{s}=200$ GeV, obtained by the pp2pp experiment using
polarized proton beams at the Relativistic Heavy Ion Collider (RHIC). Data
points were measured in the four momentum transfer $t$ range $0.01 \leq |t|
\leq 0.03$ $\GeVcSq$. Our result is about one standard deviation above the
calculation, which uses interference between electromagnetic spin-flip
amplitude and hadronic non-flip amplitude, the source of $A\_N$. The difference
could be explained by an additional contribution of a hadronic spin-flip
amplitude to $A\_N$.


title: Two Photon Width of chi_{c2}

abstract:
  The two-photon width of chi_c2 (^3P_2) state of charmonium has been measured
using 14.4 fb^-1 of e+e- data taken at sqrt{s} = 9.46-11.30 GeV with the CLEO
III detector. The two-photon fusion reaction studied is e+e- -> e+e- gamma
gamma, gamma gamma -> chi_c2 -> gamma J/psi -> gamma e+e-(mu+mu-). We measure
Gamma_{gamma gamma}(chi_c2)xBR(chi_c2 -> gamma J/psi)xBR(J/psi -> e+e- +
mu+mu-) = 13.2+-1.4(stat)+-1.1(syst) eV, and obtain Gamma_{gamma
gamma}(chi_c2)=559+-57(stat)+-48(syst)+-36(br) eV. This result is in excellent
agreement with the result of two-photon fusion measurement by Belle and is
consistent with that of the bar{p}p -> chi_c2 -> gamma gamma measurement, when
they are both reevaluated using the recent CLEO result for the radiative decay
chi_c2 -> gamma J/psi.


title: Observation of B_s Production at the Upsilon(5S) Resonance

abstract:
  Using the CLEO detector at the Cornell Electron Storage Ring, we have
observed the Bs meson in e+e- annihilation at the Upsilon(5S) resonance. We
find 14 candidates consistent with Bs decays into final states with a J/psi or
a Ds(*)-. The probability that we have observed a background fluctuation is
less than 8x10e-10. We have established that at the energy of the Upsilon(5S)
resonance Bs meson production proceeds predominantly through the creation of
Bs*Bs* pairs. We find sigma(e+e- -> Bs*Bs*) = [0.11
(+0.04-0.03)(stat.)+/-0.02(syst.)] nb, and set the following limits: sigma(e+e-
-> BsBs) / sigma(e+e- -> Bs*Bs*) < 0.16 and sigma(e+e- -> BsBs*) / sigma(e+e-
-> Bs*Bs*) < 0.16 at the 90% confidence level. The mass of the Bs* meson is
measured to be M(Bs*) = [5.414 +/- 0.001(stat.) +/- 0.003(syst.)] GeV.


title: Electroweak Measurements

abstract:
  The measurements of electroweak sector of the Standard Model are presented,
including most recent results from LEP, Tevatron and HERA colliders. The
robustness of the Standard Model is illustrated with the precision
measurements, the electroweak fits and the comparisons to the results obtained
from low energy experiments. The status of the measurements of the $W$ boson
properties and rare production processes involving weak bosons at colliders is
examined, together with the measurements of the electroweak parameters in $ep$
collisions.


title: Sides of "The" Unitarity Triangle: Results from Belle and Babar

abstract:
  The principal goal of the B-factories is to test the CKM paradigm through
measurements that overconstrain the shape of the so-called Unitarity Triangle.
The sides of the triangle are evaluated through absolute values of several
elements of the CKM matrix, so achieving high precision on these is an
important aspect of the B-factory program. Recent results from Belle and Babar
are presented.


title: Inclusive Diffractive DIS at HERA

abstract:
  Recent precision measurements of diffractive neutral current deep inelastic
ep scattering are performed by the H1 and ZEUS Collaborations at the HERA
collider in a wide range of photon virtuality Q2. The first measurements of the
large rapidity gap cross sections in charged current processes at high Q2 are
also presented. The results are compared with model predictions based on parton
density functions obtained from a DGLAP QCD fit to the data.


title: Heavy Flavors in High Energy ep Collisions

abstract:
  Most recent measurements of open charm and beauty production in high energy
ep collisions at HERA are reviewed. The measurements explored the different
aspects of quantum chromodynamics involved in the process of heavy flavor
production. The results are compared with perturbative theoretical calculations
at next-to-leading order.


title:
Measurement of the production cross-section of positive pions in p-Al
  collisions at 12.9 GeV/c

abstract:
  A precision measurement of the double-differential production cross-section,
${{d^2 \sigma^{\pi^+}}}/{{d p d\Omega}}$, for pions of positive charge,
performed in the HARP experiment is presented. The incident particles are
protons of 12.9 GeV/c momentum impinging on an aluminium target of 5% nuclear
interaction length. The measurement of this cross-section has a direct
application to the calculation of the neutrino flux of the K2K experiment.
After cuts, 210000 secondary tracks reconstructed in the forward spectrometer
were used in this analysis. The results are given for secondaries within a
momentum range from 0.75 GeV/c to 6.5 GeV/c, and within an angular range from
30 mrad to 210 mrad. The absolute normalization was performed using prescaled
beam triggers counting protons on target. The overall scale of the
cross-section is known to better than 6%, while the average point-to-point
error is 8.2%.


title: Physics at Celsius and Cosy

abstract:
  We review some selected experimental results achieved at the synchrotrons
CELSIUS in Sweden and COSY in Germany. They concentrate on meson production
with emphasis on the underlying quark structure. The project WASA at COSY is
discussed and the search for symmetry breaking in decays of $\eta$ and $\eta '$
mesons is highlighted.


title: Search for Pentaquarks at BABAR

abstract:
  The results of searches for the strange pentaquark states, Theta(1540)+,
Xi(1860)-- and Xi(1860)0 in data recorded by the BABAR experiment are
presented. We search for these three states inclusively in 123.4 fb^-1 of e+ e-
annihilation data produced at the PEP-II asymmetric storage rings; we find no
evidence for their production in any physics process, and set limits on their
production rates that are well below the measured rates for conventional
baryons. We also search for Theta(1540)+ produced in interactions of electrons
or hadrons in the material of the inner part of the detector. No evidence for
this state is found in a sample with much higher statistics than similar
electroproduction experiments that claim a signal.


title: Studies of e+e- Collisions with a Hard Initial-State Photon at BaBar

abstract:
  We present preliminary BaBar measurements of hadronic cross sections in
$e^+e^-$ annihilation using the radiative return technique. The cross sections
for $e^+e^- \to p\bar{p} $, $ 3(\pi^+\pi^-)$, $ 2(\pi^+\pi^-)2\pi^0$, and $
K^+K^-2(\pi^+\pi^-)$ are measured. Measurements of the proton form factor and
of the ratio $G_E/G_M$ are also shown.


title: Inclusive Hadronic Results at BaBar: ISR and Pentaquark Searches

abstract:
  We present recent measurements of hadronic cross-sections from the BaBar
experiment and report preliminary results on searches for pentaquark states.


title: Searches for Pentaquark Baryons at BaBar

abstract:
  This paper presents the results of inclusive searches for the strange
pentaquark states $\Theta^+(1540)$, $\Xi_5^{--}(1860)$ and $\Xi_5(1860)^{0}$ as
well as the anti-charm pentaquark state $\Theta_c(3099)^{0}$ in a dataset of
123.4 fb$^{-1}$ collected on and 40$ $MeV below the $\Upsilon(4S)$ resonance by
the BABAR detector at the $e^+e^-$ PEPII storage rings. No evidence for the
pentaquark states is found and upper limits on the rate of $\Theta^+(1540)$ and
$\Xi_5^{--}(1860)$ production in $e^+e^-$ annihilation are obtained.


title:
Measurement of the K-pi+ S-wave System in D+ to K-pi+pi+ Decays from
  Fermilab E791

abstract:
  A new approach to the analysis of three body decays is presented.
Measurements of the S-wave K pi amplitude are made in independent ranges of
invariant mass from threshold up to the upper kinematic limit in D+ to K-pi+pi+
decays. These are compared with results obtained from a fit where the S-wave is
assumed to have kappa(800) and K*0(1430) resonances. Results are also compared
with measurements of K-pi+ elastic scattering. Contributions from I = 1/2 and I
= 3/2 are not resolved in this study. If I = 1/2 dominates, however, the Watson
theorem prediction, that the phase behavour below K-eta' threshold should match
that in elastic scattering, is not well supported by these data. Production of
K-pi+ from these D decays is also studied.


title: Diffractive Dijet and Charm Production at HERA

abstract:
  Jet and charm quark production in diffractive interactions is sensitive to
the partonic structure of the diffractive exchange. This article reviews recent
cross section measurements of such processes in both deep-inelastic scattering
(DIS) regime and photoproduction (PHP) from the HERA ep collider experiments.
The cross sections are compared to next-to-leading order QCD calculations based
on factorisation theorem.


title:
Determination of the Jet Energy Scale at the Collider Detector at
  Fermilab

abstract:
  A precise determination of the energy scale of jets at the Collider Detector
at Fermilab at the Tevatron $p\bar{p}$ collider is described. Jets are used in
many analyses to estimate the energies of partons resulting from the underlying
physics process. Several correction factors are developed to estimate the
original parton energy from the observed jet energy in the calorimeter. The jet
energy response is compared between data and Monte Carlo simulation for various
physics processes, and systematic uncertainties on the jet energy scale are
determined. For jets with transverse momenta above 50 GeV the jet energy scale
is determined with a 3% systematic uncertainty.


title:
Top Quark Mass Measurement Using the Template Method in the Lepton +
  Jets Channel at CDF II

abstract:
  This article presents a measurement of the top quark mass using the CDF II
detector at Fermilab. Colliding beams of protons and anti-protons at Fermilab's
Tevatron (sqrt{s}=1.96 TeV) produce top/anti-top pairs, which decay to
W^+W^-bbbar; events are selected where one W decays to hadrons, and one W
decays to either e or mu plus a neutrino. The data sample corresponds to an
integrated luminosity of approximately 318 pb^-1. A total of 165 ttbar events
are separated into four subsamples based on jet transverse energy thresholds
and the number of b jets identified by reconstructing a displaced vertex. In
each event, the reconstructed top quark invariant mass is determined by
minimizing a chi-squared for the overconstrained kinematic system. At the same
time, the mass of the hadronically decaying W boson is measured in the same
event sample. The observed W boson mass provides an in situ improvement in the
determination of the hadronic jet energy scale, JES. A simultaneous likelihood
fit of the reconstructed top quark masses and the W boson invariant masses in
the data sample to distributions from simulated signal and background events
gives a top quark mass of 173.5 +3.7/-3.6 (stat.+JES) +/- 1.3 (other syst.)
GeV/c^2, or 173.5 +3.9/-3.8 GeV/c^2.


title:
Precision Top Quark Mass Measurement in the Lepton + Jets Topology in
  ppbar Collisions at sqrt(s) = 1.96 TeV

abstract:
  We report two measurements of the top quark mass M_top using the CDF II
detector at the Fermilab Tevatron in a 318 pb^-1 data sample observed in the
lepton + jets final state. One method uses an event-based likelihood technique
resulting in M_top = 173.2 +2.6/-2.4 (stat.) +/- 3.2 (syst.) GeV/c^2 or 173.2
+4.1/-4.0 GeV/c^2. The second method reconstructs a top quark mass in each
event using the measured invariant mass of the hadronically decaying W boson to
constrain the jet energy scale to obtain a value for M_top of 173.5 +3.7/-3.6
(stat.) +/- 1.3 (syst.) GeV/c^2 or 173.5 +3.9/-3.8 GeV/c^2. We take the latter,
which is more precise, as our result.


title: Hadron Physics at BABAR

abstract:
  The BaBar experiment at SLAC is designed to measure CP violation in the B
meson system, however the very high statistics combined with the different
electron and positron beam energies, the detector design and the open trigger
allow a wide variety of spectroscopic measurements. We are beginning to tap
this potential via several production mechanisms. Here we present recent
results from initial state radiation, hadronic jets, few body B and D hadron
decays, and interactions in the detector material. We also summarize
measurements relevant to Ds meson spectroscopy, pentaquarks and charmonium
spectroscopy from multiple production mechanisms.


title: Search for the W-exchange decays B0 --> Ds(*)- Ds(*)+

abstract:
  We report a search for the decays $B^{0} \to D_{s}^{-} D_{s}^{+}$, $B^{0} \to
D_{s}^{*-} D_{s}^{+}$, $B^{0} \to D_{s}^{*-} D_{s}^{*+}$ in a sample of 232
million $\Upsilon(4S)$ decays to \BBb ~pairs collected with the \babar detector
at the PEP-II asymmetric-energy $e^+ e^-$ storage ring. We find no significant
signal and set upper bounds for the branching fractions: ${\cal B}(B^{0} \to
D_{s}^{-} D_{s}^{+}) < 1.0 \times 10^{-4}, {\cal B}(B^{0} \to D_{s}^{*-}
D_{s}^{+}) < 1.3 \times 10^{-4}$ and ${\cal B}(B^{0} \to D_{s}^{*-} D_{s}^{*+})
< 2.4 \times 10^{-4}$ at 90% confidence level.


title: Charm Decays Within the Standard Model and Beyond

abstract:
  The charm quark has unique properties that make it a very important probe of
many facets of the Standard Model. New experimental information on charm decays
is becoming available from dedicated experiments at charm factories, and
through charm physics programs at the b-factories and hadron machines. In
parallel, theorists are working on matrix element calculations based on
unquenched lattice QCD, that can be validated by experimental measurements and
affect our ultimate knowledge of the quark mixing parameters. Recent
predictions are compared with corresponding experimental data and good
agreement is found. Charm decays can also provide unique new physics
signatures; the status of present searches is reviewed. Finally, charm data
relevant for improving beauty decay measurements are presented.


title:
Analysis of the Kpi hadronic state interaction using D into K-pi+mu+nu
  semileptonic decays from the FOCUS experiment

abstract:
  We present a four-body semileptonic charm decay D^+ into K^-pi^+mu^+nu
analysis in the range of 0.65 GeV/c^2 < mkpi < 1.5 GeV/c^2. We observe a low
mass scalar contribution of 5.30 +- 0.74 + 0.99 - 0.96 % with respect to the
total D^+ into K^-pi^+mu^+nu decay, compatible with the phase shift found by
the LASS elastic scattering experiment. For the K*(892) resonance, we obtain a
mass of 895.41 +- 0.32 + 0.35 - 0.43 MeV/c^2, a width of 47.79 +- 0.86 + 1.32 -
1.06 MeV/c^2, and a Blatt-Weisskopf damping factor parameter of 3.96 +- 0.54 +
1.31 - 0.90 GeV^(-1). We also report 90% CL upper limits of 4% and 0.64% for
the branching ratios Gamma(D^+ into K*(1680)mu^+nu)/Gamma(D^+ into
K^-pi^+mu^+nu) and Gamma(D^+ into K*_0(1430)mu^+nu)/Gamma(D^+ into
K^-pi^+mu^+nu), respectively.


title:
$e^{+}e^{-}$ pairs from a nuclear transition signaling an elusive light
  neutral boson

abstract:
  Electron-positron pairs have been observed in the 10.95-MeV $0^-\to0^+$ decay
in $^{16}$O. The branching ratio of the e$^+$e$^-$ pairs compared to the
3.84-MeV $0^-\to2^+$ $\gamma$ decay of the level is deduced to be
$20(5)\times10^{-5}$. This magnetic monopole (M0) transition cannot proceed by
$\gamma$-ray decay and is, to first order, forbidden for internal pair
creation. However, the transition may also proceed by the emission of a light
neutral $0^{-}$ or $1^{+}$ boson. Indeed, we do observe a sharp peak in the
$e^{+}e^{-}$ angular correlation with all the characteristics belonging to the
intermediate emission of such a boson with an invariant mass of 8.5(5)
MeV/c$^2$. It may play a role in the current quest for light dark matter in the
universe.


title: Intense Muon Physics Working Group Summary

abstract:
  The intense muon beams which will be available at a neutrino factory provide
a unique opportunity for searching for physics beyond the standard model, both
in lepton flavor violation and in the search for a permanent electric dipole
moment for the muon. Other experiments which can use intense muon beams will
also be possible.


title: Muon (g-2): Past, Present and Future

abstract:
  The muon (g-2) experiment E821 at the Brookhaven National Laboratory has
achieved a relative precision of $\pm 0.5$ parts per million.
  A new experiment, E969, with scientific approval but not yet funded, aims to
improve this to $\pm 0.2$ ppm. The technique and results from E821 will be
described, and the proposed improvements for E969 will be discussed.


title: Results of the searches for pentaquarks with strangeness in DIS at HERA

abstract:
  The K0s-p invariant mass spectrum was reconstructed in several kinematic
regions with the main emphasis on the studies of the production mechanism of
the Theta+ candidate recently observed by ZEUS. The candidate Theta+ signal was
found to be produced predominantly in the forward hemisphere in the laboratory
frame. This is unlike the case for the Lambda(1520) or the Lambda(c), and
indicates that the Theta+ may have an unusual production mechanism related to
proton-remnant fragmentation. H1 does not observe a signal and sets an upper
limit at 95% C.L. which does not exclude the ZEUS observation.


title: Rare B Decays and B Decay Dynamics

abstract:
  I present some recent measurements of B meson decay rates to leptonic and
charmless hadronic final states, as well as of CP-violation charge asymmetries
and other features. I sketch the theoretical frameworks used to predict these,
and indicate the level of agreement of the estimates with experiment.


title: Dalitz Analysis of B=>Khh Decays at Belle

abstract:
  We report results on the Dalitz analysis of three-body charmless
B+=>K+pi+pi-, B0=>K0pi+pi- and B+=>K+K+K- decays including searches for direct
CP violation in the B+=>K+pi+pi- mode. Branching fractions for a number of
quasi-two-body intermediate states are reported. We also observe evidence with
3.9 sigma significance for a large direct CP violation in B+-=>rho(770)0K+-
channel. This is the first evidence for CP violation in a charged meson decay.
The results are obtained using a Dalitz analysis technique with a large data
sample of BBbar pairs collected with the Belle detector operating at the KEKB
asymmetric energy e+e- collider.


title: Double Chooz: Optimizing CHOOZ for a possible theta 13 measurement

abstract:
  The proposed Double Chooz theta 13 experiment is described. Double Chooz will
be an optimized reactor disappearance experiment similar to the original CHOOZ.
The optimization includes an increase in the signal to noise by increasing the
target volume to twice the original CHOOZ, reducing singles background with a
non-scintillating oil buffer region around the target and carefully controlling
systematic uncertainties by measuring the electron antineutrino flux of the
source with a near detector. The Double Chooz far detector will be situated in
the same cavern as CHOOZ but will detect ~50000 electron antineutrinos in three
years of operation. We estimate a systematic uncertainty of 0.6%, and a
reduction of the upper limit on theta 13 to 5 degrees.


title:
Search for $\Theta^+(1540)$ pentaquark in high statistics measurement of
  $\gamma p \to \bar K^0 K^+ n$ at CLAS

abstract:
  The exclusive reaction $\gamma p \to \bar K^0 K^+ n$ was studied in the
photon energy range between 1.6-3.8 GeV searching for evidence of the exotic
baryon $\Theta^+(1540)\to nK^+$. The decay to $nK^+$ requires the assignment of
strangeness $S=+1$ to any observed resonance. Data were collected with the CLAS
detector at the Thomas Jefferson National Accelerator Facility corresponding to
an integrated luminosity of 70 $pb^{-1}$. No evidence for the $\Theta^+$
pentaquark was found. Upper limits were set on the production cross section as
function of center-of-mass angle and $nK^+$ mass. The 95% CL upper limit on the
total cross section for a narrow resonance at 1540 MeV was found to be 0.8 nb.


title: Hadron Spectroscopy from BES and CLEOc

abstract:
  Recent results from BES and CLEOc experiments on hadron spectroscopy and
charmonium decays using J/psi, psi' and psi'' data samples collected in e+e-
annihilation are reviewed, including the observation of X(1835) in J/psi -->
gamma pi+ pi- eta', study of the scalar particles in J/psi radiative and
hadronic decays, as well as in chi_c0 hadronic decays, and the study of the
``\rho\pi puzzle'' in J/psi, psi', and psi'' decays. We also make a few
comments on partial wave analysis, and the study of the \rho \pi puzzle.


title:
A search for top decay into tau, neutrino and quark in top-antitop
  production

abstract:
  We present a search for top-antitop events with a tau lepton in the final
state. The data sample corresponds to an integrated luminosity of 194/pb
collected with the CDF II detector from proton-antiproton collisions at a
center of mass energy of 1.96 TeV. We observe two events with an expected
signal of 1.0+/-0.2 events and a background of 1.3+/-0.3 events. We determine a
95% confidence level upper limit on r_tau, the ratio of the measured rate of
top->tau nu quark to the expectation, of 5.2.

branching ratio is measured.


title:
Search for charged Higgs bosons from top quark decays in \ppbar
  collisions at $\sqrt{s}=1.96$ TeV

abstract:
  We report the results of a search for a charged Higgs boson in the decays of
top quarks produced in \ppbar collisions at a center-of-mass energy of 1.96
TeV. We use a data sample corresponding to an integrated luminosity of 193/pb
collected by the upgraded Collider Detector at Fermilab. No evidence for
charged Higgs production is found, allowing 95% C.L. upper limits to be placed
on BR(t->H^+b) for different charged Higgs decay scenarios. In addition, we
present in the MSSM (mH,tan beta) plane the first exclusion regions with
radiative and Yukawa coupling corrections.


title:
Measurement of the branching fractions for $J/\psi\to\gamma\pi^0$,
  $\gamma\eta$ and $\gamma\eta^{\prime}$

abstract:
  The decay modes $\jpsi\ar\gamma\pi^0, \gamma\eta$ and $\gamma\etap$ are
analyzed using a data sample of 58 million $\jpsi$ decays collected with the
BESII detector at BEPC. The branching fractions are determined to be:
  $Br(\jpsi\ar\gamma\pi^0)=(3.13^{+0.65}_{-0.44})\times10^{-5}$,
  $Br(\jpsi\ar\gamma\eta)=(11.23\pm0.89)\times10^{-4}$, and
  $Br(\jpsi\ar\gamma\etap)=(5.55\pm0.44)\times10^{-3}$,
  where the errors are combined statistical and systematic errors. The ratio of
partial widths $\Gamma(\jpsi\ar\gamma\etap)/\Gamma(\jpsi\ar\gamma\eta)$ is
measured to be $4.94\pm0.40$, and the singlet-octet pseudoscalar mixing angle
of $\eta-\etap$ system is determined to be
$\theta_{P}=(-22.08\pm0.81)^{\circ}$.


title: Search for the $\Theta^+$ in Photoproduction on the Deuteron

abstract:
  A high-statistics experiment on a deuterium target was performed using a real
photon beam with energies up to 3.6 GeV at the CLAS detector of Jefferson Lab.
The reaction reported here is for $\gamma d \to p K^- K^+ n$ where the neutron
was identified using the missing mass technique. No statistically significant
narrow peak in the mass region from 1.5-1.6 GeV was found. An upper limit on
the elementary process $\gamma n \to K^- \Theta^+$ was estimated to be about
4-5 nb, using a model-dependent correction for rescattering determined from
$\Lambda$(1520) production. Other reactions with less model-dependence are
being pursued.


title:
A partial wave analysis of the $\pi^- \pi^- \pi^+$ and $\pi^- \pi^0
  \pi^0$ systems and the search for a $J^{PC}=1^{-+}$ meson

abstract:
  A partial wave analysis (PWA) of the $\pi^- \pi^- \pi^+$ and $\pi^- \pi^0
\pi^0$ systems produced in the reaction $\pi^- p \to (3\pi)^-p$ at 18 GeV/$c$
was carried out using an \emph{isobar} model assumption. This analysis is based
on 3.0M $\pi^- \pi^0 \pi^0$ events and 2.6M $\pi^- \pi^-\pi^+$ events and shows
production of the $a_1(1260)$, $a_2(1320)$, $\pi_2(1670)$ and $a_4(2040)$
resonances. Results of detailed studies of the stability of partial wave fits
are presented. An earlier analysis of 250K $\pi^- \pi^- \pi^+$ events from the
same experiment showed possible evidence for a $J^{PC}=1^{-+}$ exotic meson
with a mass of $\sim$1.6 GeV/$c^2$ decaying into $\rho \pi$. In this analysis
of a higher statistics sample of the $(3\pi)^-$ system in two charged modes we
find no evidence of an exotic meson.


title: B meson mixing at CDF II

abstract:
  We present the first limit on Bs mixing frequency obtained using 360 pb^-1 of
Tevatron Run II data with the CDF II detector. We derive Delta ms 7.9 ps^-1 @
95 % C.L. with a sensitivity of 8.4 ps^-1. -


title:
Measurements of the Absolute Branching Fractions of B^\pm --> K^\pm
  X_{c\bar c}

abstract:
  We study the two-body decays of B^\pm mesons to K^\pm and a charmonium state,
X_{c\bar c}, in a sample of 210.5 fb^{-1} of data from the BaBar experiment. We
perform measurements of absolute branching fractions BR(B^\pm --> K^\pm
X_{c\bar c}) using a missing mass technique, and report several new or improved
results. In particular, the upper limit BR(B^\pm --> K^\pm X(3872))<3.2 10^-4
at 90% CL and the inferred lower limit BR(X(3872) --> J/\psi\pi^+\pi^-)>4.2%
will help in understanding the nature of the recently discovered X(3872).


title: Jets in ep and gammap Scattering at HERA

abstract:
  Recent jet physics results from ep and $\gamma$p scattering at HERA will be
reviewed covering cross-section measurements, the extraction of QCD parameters,
the transition region from photoproduction to deep-inelastic scattering and the
question of parton evolution in the proton.

Scattering (DVCS) from ZEUS and H1 experiments are presented.

detector is presented. The future plans for the experiments with upgraded
SVD-2M setup is discussed.


title:
Observation of B^+ -> \bar{\Xi}_c^0\Lambda_c^+ and Evidence for B^0 ->
  \bar{\Xi}_c^-\Lambda_c^+

abstract:
  We report the first observation of the decay B+ -> \bar{\Xi}_c^0 \Lambda_c^+
with a significance of 8.7 \sigma and evidence for the decay B^0 ->
\bar{\Xi}_c^-\Lambda_c^+ with a significance of 3.8 \sigma. The product Br(B^+
-> \bar{\Xi}_c^0\Lambda_c^+)\times Br(\bar{\Xi}_c^0 -> \bar{\Xi}^+\pi^-) is
measured to be (4.8^{+1.0}_{-0.9}\pm 1.1\pm 1.2)\times 10^{-5}, and Br({B^0} ->
\bar{\Xi}_c^-\Lambda_c^+)\times Br(\bar{\Xi}_c^- -> \bar{\Xi}^+\pi^-\pi^-) is
measured to be (9.3^{+3.7}_{-2.8}\pm 1.9\pm 2.4)\times 10^{-5}. The errors are
statistical, systematic and the error of the \Lambda_c^+ -> pK^-\pi^+ branching
fraction, respectively. The decay B^+ -> \bar{\Xi}_c^0\Lambda_c^+ is the first
example of a two-body exclusive B^+ decay into two charmed baryons. The data
used for this analysis was accumulated at the \Upsilon(4S) resonance, using the
Belle detector at the e^+ e^- asymmetric-energy collider KEKB. The integrated
luminosity of the data sample is equal to 357 {fb}^{-1}, corresponding to
386\times 10^{6} B{\bar B} pairs.


title: PWA of 3pi Final States and a Search for the pi1(1600)

abstract:
  Partial wave analyses (PWA) of the 3pi systems in the reactions pi- p --> pi+
pi- pi- p (the ``charged'' mode) and pi- p --> pi- pi0 pi0 p (the ``neutral''
mode) with an 18.3 GeV/c pion beam were performed using high statistics data
from the E852 experiment. Conventional signals, such as the a1(1260), the
a2(1320), and the pi2(1670), were found to be remarkably stable to the choice
of waves included in the fit. In contrast, possible evidence for the pi1(1600)
in the JPC = 1-+ exotic wave amplitude disappears when additional decay modes
of conventional mesons (especially those of the pi2(1670)) are included in the
PWA fit.


title: Bremsstrahlung in Leptonic Onia Decays: Effects on Mass Spectra

abstract:
  In this note we present a study of the radiative tails in the invariant mass
spectra of muon or electron pairs from J/psi, psi(2S) and Upsilon(1S) decays
which is due to an additional emission of a photon. An analytic formula for
dilepton mass spectra in radiative decays is derived and a Monte Carlo
simulation for realistic detector conditions is used to study effects on the
spectra. A rather simple parameterisation is given, suitable for the treatment
of real data.


title: Combination of CDF and D0 Results on the W-Boson Width

abstract:
  The results on the direct measurements of the W-boson width, based on the
data collected by the Tevatron experiments CDF and D{\O}at Fermilab during
{\RunI} from 1992 to 1996 and {\RunII} since 2001 are summarized. The
combination of the published {\RunI} and preliminary {\RunII} results, taking
correlated uncertainties properly into account, is presented. The resulting
preliminary Tevatron average for the total decay width of the W boson is:
$\GW=2078\pm87 \MeV$, where the total error consists of a statistical part of
$62 \MeV$ and a systematic part of $60 \MeV$.


title: Elastic Cross-Section and Luminosity Measurement in ATLAS at LHC

abstract:
  Recently the ATLAS experiment was complemented with a set of
ultra-small-angle detectors located in ``Roman Pot'' inserts at 240m on either
side of the interaction point, aiming at the absolute determination of the LHC
luminosity by measuring the elastic scattering rate at the Coulomb Nuclear
Interference region. Details of the proposed measurement the detector
construction and the expected performance as well as the challenges involved
are discussed here.


title: Multi Jet Production at High Q2

abstract:
  Deep-inelastic $e^+p$ scattering data, taken with the H1 detector at HERA,
are used to investigate jet production over a range of four-momentum transfers
$150 < Q^2 < 15000 \mathrm{GeV}^2$ and transverse jet energies $5 < E_T < 50
\mathrm{GeV}$. The analysis is based on data corresponding to an integrated
luminosity of $\mathcal{L}_\mathrm{int} = 65.4 \mathrm{pb}^{-1}$ taken in the
years 1999-2000 at a centre-of-mass energy $\sqrt{s} \approx 319 \mathrm{GeV}$.
Jets are defined by the inclusive $k_t$ algorithm in the Breit frame of
reference. Dijet and trijet jet cross sections are measured with respect to the
exchanged boson virtuality and in addition the ratio of the trijet to the dijet
cross section $R_{3/2}$ is investigated. The results are compared to the
predictions of perturbative QCD calculations in next-to-leading order in the
strong coupling constant $\alpha_s$. The value of $\alpha_s(m_Z)$ determined
from the study of $R_{3/2}$ is $\alpha_s(m_Z) = 0.1175 \pm 0.0017
(\mathrm{stat.}) \pm 0.0050 (\mathrm{syst.}) ^{+0.0054}_{-0.0068}
(\mathrm{theo.})$.


title:
Studies of heavy flavour production and the hadronic final state in high
  energy ep collisions

abstract:
  An extract of recent results from the H1 and ZEUS Collaborations is shown.
Various properties of quantum chromo dynamics are investigated by studying the
details of the hadronic final state of high energy electron proton collisions
at HERA. The presented results include analyses of jet cross sections and
single particle production such as $\gamma$ and $D$. Part of the measurements
deal with final states involving identified heavy quarks (charm and beauty).


title: Spectroscopy at HERA

abstract:
  Recent results on spectroscopy with special focus on searches for pentaquarks
are presented from the H1 and ZEUS collaborations. Cross sections of observed
states and upper limits on the production cross section of unobserved states
are extracted in order to enable comparison between experiments. Measurements
of the inclusive photoproduction of the neutral mesons eta, rho^0, f_0(980) and
f_2(1270) in ep interactions at HERA at an average gamma-p collision energy of
210 GeV are also presented.


title: High momentum particle and jet production in photon-photon collisions

abstract:
  Jet and particle production have been studied in collisions of quasi-real
photons collected during the LEP2 program. OPAL and DELPHI report good
agreement of NLO perturbative QCD with the measured differential di-jet cross
sections, which reach a mean transverse energy of the di-jet system of 25 GeV.
L3, on the other hand, finds drastic disagreement of the same calculation with
single jet production for transverse jet momenta larger than about 25 GeV. L3
observes similar disagreement between data and NLO QCD in their measurements of
charged and neutral particle production at high transverse momenta of the
particles. A recent measurement performed by DELPHI of the same quantities does
not confirm this observation.


title:
Research Program towards Observation of Neutrino-Nucleus Coherent
  Scattering

abstract:
  The article describes the research program pursued by the TEXONO
Collaboration towards an experiment to observe coherent scattering between
neutrinos and the nucleus at the power reactor. The motivations of studying
this process are surveyed. In particular, a threshold of 100-200 eV has been
achieved with an ultra-low-energy germanium detector prototype. This detection
capability at low energy can also be adapted to conduct searches of Cold Dark
Matter in the low-mass region as well as to enhance the sensitivities in the
study of neutrino magnetic moments.


title: Prospects for Antineutrino Running at MiniBooNE

abstract:
  We outline a program of antineutrino cross-section measurements necessary for
the next generation of neutrino oscillation experiments, that can be performed
with one year of data at MiniBooNE. We describe three independent methods of
constraining wrong-sign (neutrino) backgrounds in an antineutrino beam, and
their application to the MiniBooNE antineutrino cross section measurements.


title: Spectroscopy and new particles

abstract:
  The properties of three new particles X(3872), Y(3940) and Z(3931), recently
dicovered by the Belle collaboration, are briefly reviewed. Negative results of
the search for the pentaquark $\Theta(1540)^+$ are also presented


title: Heavy flavour production in high-energy ep collisions

abstract:
  A selection of recent results on heavy quark production at the HERA collider
by the H1 and ZEUS collaborations are presented with a focus on charmonium
production in DIS, charm fragmentation and beauty production.

abstract:
  The physics potential of a Beta Beam fired from CERN to a 440 kton water
Cerenkov detector at a distance of 130 Km is computed.


title: Diffractive Interactions in ep Collisions

abstract:
  The H1 and ZEUS experiments are measuring diffractive interactions in ep
collisions at HERA. Performing QCD fits of these data with NLO DGLAP,
diffractive parton distribution functions can be calculated. These diffractive
PDFs can be used to test QCD factorisation with dijet and charm data.


title: Studies of the Bc Meson at CDF

abstract:
  We present the latest measurements of the Bc meson properties using 360 pb-1
of data collected by the CDF detector in RUN II. The results include the Bc
mass and the ratio of branching fraction Bc->J/psi+l with respect to
B->J/psi+K.
