title: Recent Physics results with the COMPASS Experiment

abstract:
  The COMPASS experiment has obtained first physics results in the field of
polarized distribution functions for quarks and gluons using muon scattering
off polarized deuterons. The analysis using open charm production and pairs of
high $p_T$ hadrons is presented. We also have used a transversely polarized
target to address transverse information for quarks inside the nucleon. In
addition, a pilot run with incoming pions taken late 2004 will give first
information on the pion polarizabilities and hadron resonances. The physics
prospects from this run as well as from future data taking in this field are
also outlined.


title: B_s Properties at the Tevatron

abstract:
  The Tevatron collider at Fermilab provides a very rich environment for the
study Bs mesons. In this paper we will show a few selected topics from the CDF
and D0 collaborations, giving special attention to the Bs Mixing analyses. This
note corresponds to the proceedings of the Hadron Collider Physics 2005
conference.


title: CKM Parameters and Rare B Decays

abstract:
  Measurements of the angles and sides of the unitarity triangle and of the
rates of rare B meson decays are crucial for the precise determination of
Standard Model parameters and are sensitive to the presence of new physics
particles in the loop diagrams. In this paper the recent measurements performed
in this area by Babar and Belle will be presented. The direct measurement of
the angle alpha is for the first time as precise as the indirect determination.
The precision of the V_ub determination has improved significantly with respect
to previous measurement. New limits on B->tau nu decays are presented, as well
as updated measurements on b->s radiative transitions and a new observation of
b->d gamma transition made by Belle.


title: Searches for BSM (non-SUSY) Physics at the Tevatron

abstract:
  Results of searches at the Tevatron for physics (non-SUSY and non-Higgs)
beyond the Standard Model using 200/pb to 480/pb of data are discussed.
Searches at DO and CDF for Z', Lepton-Quark compositeness, Randall-Sundrum
Gravitons, Large Extra Dimensions, W', Leptoquarks and Excited Electrons are
presented here.


title:
Comparison of inclusive particle production in 14.6 GeV/c proton-nucleus
  collisions with simulation

abstract:
  Inclusive charged pion, kaon, proton, and deuteron production in 14.6 GeV/c
proton-nucleus collisions measured by BNL experiment E802 is compared with
results from the GEANT3, GEANT4, and FLUKA simulation packages. The FLUKA
package is found to have the best overall agreement.


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: Discovery potential of R-hadrons with the ATLAS detector

abstract:
  The production of exotic heavy hadronic particles arise in several models for
physics beyond the Standard Model. A study of the detection possibilities of
new heavy hadron states with the ATLAS detector is presented. The focus is on
R-hadrons, which are stable hadronized gluinos, predicted by certain
supersymmetric models. Interactions and signatures of single R-hadrons are
studied with the ATLAS simulation and reconstruction framework and issues
concerning triggering on R-hadron events are addressed. The ATLAS fast
simulation framework has been extended to include parameterizations for
R-hadrons. Based on topological and kinematic variables only, the discovery
potential of the ATLAS detector for R-hadron events produced in pp->g~g~, is
studied for masses below 2 TeV/c^2. R-hadrons with masses as predicted by
standard SUSY scenarios would be discovered already in the very early stages of
the running of the LHC. The discovery reach of heavy gluinos, predicted by for
example split supersymmetry models, extends up to at least 1.8 \tevcc for three
years running of the LHC at low luminosity.


title: A Search for the rare decay B0 --> tau+tau- at BABAR

abstract:
  We present the results of a search for the decay B0 --> tau+tau- in a data
sample of (232 +- 3) x 10^6 Upsilon(4S) --> BBbar decays using the BABAR
detector. Certain extensions of the Standard Model predict measurable levels of
this otherwise rare decay. We reconstruct fully one neutral B meson and seek
evidence for the signal decay in the rest of the event. We find no evidence for
signal events and obtain B(B0 --> tau+tau-) < 4.1 x 10^-3 at the 90% confidence
level.


title: Measurements of the CKM Angle beta

abstract:
  In this article I report on new and updated measurements of the CP-violating
parameter beta (phi_1), which is related to the phase of the
Cabibbo-Kobayashi-Maskawa (CKM) quark-mixing matrix of the electroweak
interaction. Over the past few years, beta has become the most precisely known
parameter of the CKM unitarity triangle that governs the B system. The results
presented here were produced by the two B factories, BaBar and Belle, based on
their most recent datasets of over 600 million BB events combined. The new
world average for sin(2beta), measured in the theoretically and experimentally
cleanest charmonium modes, such as B -> J/psi K0s, is sin(2beta) = 0.685 +-
0.032. In addition to these tree-level dominated decays, independent
measurements of sin(2beta) are obtained from gluonic b --> s penguin decays,
including B --> phi K0s, B --> eta' K0s and others. There are hints, albeit
somewhat weaker than earlier this year, that these measurements tend to come
out low compared to the charmonium average, giving rise to the tantalizing
possibility that New Physics amplitudes could be contributing to the
corresponding loop diagrams. Clearly, more data from both experiments are
needed to elucidate these intriguing differences.


title:
Inclusive production of $\Lambda$, $K^0_s$ and exotic narrow resonances
  for systems $K_s^0 p$, $K_s^0 \Lambda$, $\Lambda p$ from p+propane
  interactions at 10 GeV/c

abstract:
  Experimental data from the 2m propane bubble chamber for production of
$\Lambda$, $K^0_s$ have been used to search of exotic baryon states, in the
$K_s^0 p$, $K_s^0 \Lambda$ and $\Lambda p$ decay mode for the reaction
p+propane at 10 GeV/c. The estimation of experimental inclusive cross sections
for $\Lambda$ and $K^0_s$ production in the p$^{12}C$ collision is equal to
$\sigma_{\Lambda}$= 13.3$\pm$1.7 mb and $\sigma_{K^0_s}$= 3.8$\pm$0.6 mb,
respectively. The measured $\Lambda /\pi^+$ ratio from pC reaction is equal to
(5.3$\pm0.8)*10^{-2}$. The experimental $\Lambda /\pi^+$ ratio from the pC
reaction is approximately two times larger than the $\Lambda /\pi^+$ ratio
simulated by FRITIOF model from the pC reaction.
  The invariant mass spectrum $\Lambda K^0_s$ registered narrow peaks in
regions of 1750 and 1795 MeV/$c^2$. The statistical significance of these peaks
has been estimated as 5.6 and 3.3 S.D., respectively. These would be candidates
for the $N^0$ or the $\Xi^0$ pentaquark states.
  The $pK^0_s$ invariant mass spectrum shows resonant structures with $M_{K_s^0
p}$=1540, 1613, 1821 MeV/$c^2$. The statistical significance of these peaks
have been estimated as 5.5,4.8 and 5.0 s.d., respectively.
  The invariant mass spectrum S=-1 $\Lambda p$ observed a narrow peaks at 2100,
2175,2285 and 2353 MeV/$c^2$. Their excess above background by the second
method is 6.9, 4.9, 3.8 and 2.9 S.D., respectively.


title: Precision Tests of the Standard Model

abstract:
  Recent published and preliminary precision electroweak measurements are
reviewed, including new results on the mass of the top quark and mass and width
of the W boson. The experimental results are compared with the predictions of
the Standard Model and are used to constrain its free parameters, notably the
mass of the Higgs boson. The agreement between measurements and expectations
from theory is discussed.

21st to 27th, 2005)


title: Experimental Study of chi_b(2P) --> pi pi chi_b(1P)

abstract:
  We have searched for the di-pion transition chi_b(2P) -> pi pi chi_b(1P) in
the CLEO III sample of Upsilon(3S) decays in the exclusive decay chain:
Upsilon(3S) -> gamma chi_b(2P), chi_b(2P) -> pi pi chi_b(1P), chi_b(1P) ->
gamma Upsilon(1S), Upsilon(1S) -> lepton pairs. Our studies include both pi+
pi- and pi0 pi0, each analyzed both in fully reconstructed events and in events
with one pion undetected. We show that the null hypothesis is not
substantiated. Under reasonable assumptions, we find the partial decay width to
be Gamma[chi_b(2P) -> pi pi chi_b(1P)] = (0.83 +/- 0.22 +/- 0.08 +/- 0.19) keV,
with the uncertainties being statistical, internal CLEO systematics, and common
systematics from outside sources.


title: Structure Function Measurements at the LHC

abstract:
  Since the current uncertainty on the structure of the proton affects the new
physics discovery potential of LHC, the ATLAS collaboration is investigating
methods to constrain this uncertainty over the whole LHC kinematic regime. The
Standard Model processes such as direct photon, Z, W and inclusive jet
productions are optimal candidates for this purpose.


title: Search for eta_c decays into pi pi and K Bar K

abstract:
  Using 58 million $J/\psi$ events taken with the BESII detector, a search for
$eta_{c}$ CP violating decays into $\pi\pi$ and $\bar{K}K$ has been performed.
No clear $eta_{c}$ is observed, and upper limits for $B(eta_{c}->\pi \pi)$and
$B(eta_{c}->\bar{K} K)$ are given at the 90% confidence level,
$B(J/\psi->\gamma\eta_{c})\times B(eta_{c}->\pi^{+}\pi^{-})<1.1\times 10^{-5}$
, $B(J/\psi->\gamma\eta_{c})\times B(eta_{c}->\pi^{0}\pi^{0})<0.71\times
10^{-5}$, $B(J/\psi->\gamma\eta_{c})\times B(eta_{c}->K^{+}K^{-})<0.96\times
10^{-5}$ and $B(J/\psi->\gamma\eta_{c})\times
B(eta_{c}->{K_{s}}^{0}{K_{s}}^{0})<0.53\times 10^{-5}$.


title:
New Measurement of BR(D+ ->Rho0 Mu+ Nu) / BR(D+ ->K*0 Mu+ Nu) Branching
  Ratio

abstract:
  Using data collected by the FOCUS experiment at Fermilab, we present a new
measurement of the charm semileptonic branching ratio BR(D+ -> rho0 mu+
nu)/BR(D+ -> K*0 mu+ nu). From a sample of 320+-44 and 11372+-161 D+ -> rho0
mu+ nu and D+ -> K*0 mu+ nu events respectively, we find BR(D+ -> rho0 mu+
nu)/BR(D+ -> K*0 mu+ nu)=0.041+-0.006(stat)+-0.004(syst).


title: Measurement of the Helicity of W Bosons in Top-Quark Decays

abstract:
  We measure the branching fraction of the top quark to longitudinally and
right-handed polarized $W$ bosons, $F_0$ and $F_+$, using approximately 200
pb$^{-1}$ of $\bar{p}p$ collisions collected by the CDF II detector. We analyze
two quantities sensitive to the $W$ helicity: the invariant mass of the charged
lepton and the bottom-quark jet in the decay $t\to Wb \to \ell\nu b$ (where
$\ell=e$ or $\mu$), and the transverse momentum of the charged lepton. We find
$F_0=0.74^{+0.22}_{-0.34}$, and $F_+<0.27$ at the 95% confidence level. These
measurements are in agreement with the standard model predictions.


title:
High Transverse Momentum Xi Baryon Correlations in p+p Collisions at
  s^(1/2)=200 GeV

abstract:
  Angular correlations between produced high pT Xi baryons and unidentified
charged and neutral particles are observed in high-tower-triggered (on a large
electromagnetic energy deposit) s^(1/2)=200 GeV p+p collisions. This trigger
favors events with higher average multiplicity than those in minimum bias.
These events are likely to contain jets. The average multiplicity of a
high-tower triggered event is similar to that of a minimum bias event
containing a Xi, which implies that Xi baryons are likely to be produced in
jets. Xi mean pT is higher in the triggered data then in the minimum bias
sample.


title: Top Quark Measurements

abstract:
  Ten years after its discovery at the Tevatron collider, we still know little
about the top quark. Its large mass suggests it may play a key role in the
mechanism of Electroweak Symmetry Breaking (EWSB), or open a window of
sensitivity to new physics related to EWSB and preferentially coupled to it. To
determine whether this is the case, precision measurements of top quark
properties are necessary. The high statistics samples being collected by the
Tevatron experiments during Run II start to incisively probe the top quark
sector. This report summarizes the experimental status of the top quark,
focusing in particular on the recent measurements from the Tevatron Run II.


title:
Measurement of branching fractions for the inclusive Cabibbo-favored
  ~K*0(892) and Cabibbo-suppressed K*0(892) decays of neutral and charged D
  mesons

abstract:
  The branching fractions for the inclusive Cabibbo-favored ~K*0 and
Cabibbo-suppressed K*0 decays of D mesons are measured based on a data sample
of 33 pb-1 collected at and around the center-of-mass energy of 3.773 GeV with
the BES-II detector at the BEPC collider. The branching fractions for the
decays D+(0) -> ~K*0(892)X and D0 -> K*0(892)X are determined to be BF(D0 ->
\~K*0X) = (8.7 +/- 4.0 +/- 1.2)%, BF(D+ -> ~K*0X) = (23.2 +/- 4.5 +/- 3.0)% and
BF(D0 -> K*0X) = (2.8 +/- 1.2 +/- 0.4)%. An upper limit on the branching
fraction at 90% C.L. for the decay D+ -> K*0(892)X is set to be BF(D+ -> K*0X)
< 6.6%.


title:
A Combination of Preliminary Electroweak Measurements and Constraints on
  the Standard Model

abstract:
  This note presents a combination of published and preliminary electroweak
results from the four LEP collaborations ALEPH, DELPHI, L3 and OPAL based on
electron-positron collision data taken at centre-of-mass energies above the
Z-pole, $130 \GeV$ to $209 \GeV$ (\LEPII), as prepared for the 2005 summer
conferences. Averages are derived for di-fermion cross sections and
forward-backward asymmetries, photon-pair, W-pair, Z-pair, single-W and
single-Z cross sections, electroweak gauge boson couplings, W mass and width
and W decay branching ratios. An investigation of the interference of photon
and Z-boson exchange is presented, and colour reconnection and Bose-Einstein
correlation analyses in W-pair production are combined. The main changes with
respect to the experimental results presented in 2004 are updates to some
4-fermion cross sections, final results on BE correlations and a new
preliminary combination of the mass and width of the W boson.
  Including the precision electroweak measurements performed at the Z pole
published recently, the results are compared with precise electroweak
measurements from other experiments, notably CDF and D{\O}at the Tevatron.
Constraints on the input parameters of the Standard Model are derived from the
results obtained in high-$Q^2$ interactions, and used to predict results in
low-$Q^2$ experiments, such as atomic parity violation, Moller scattering, and
neutrino-nucleon scattering.


title:
Gluon polarization in the nucleon from quasi-real photoproduction of
  high-pT hadron pairs

abstract:
  We present a determination of the gluon polarization Delta G/G in the
nucleon, based on the helicity asymmetry of quasi-real photoproduction events,
Q^2<1(GeV/c)^2, with a pair of large transverse-momentum hadrons in the final
state. The data were obtained by the COMPASS experiment at CERN using a 160 GeV
polarized muon beam scattered on a polarized 6-LiD target. The helicity
asymmetry for the selected events is <A_||/D> = 0.002 +- 0.019(stat.) +-
0.003(syst.). From this value, we obtain in a leading-order QCD analysis Delta
G/G=0.024 +- 0.089(stat.) +- 0.057(syst.) at x_g = 0.095 and mu^2 =~ 3
(GeV}/c)^2.


title:
Measurements of $J\psi$ decays into $\omega\pi^0$, $\omega\eta$, and
  $\omega\eta'$

abstract:
  Based on $5.8 \times 10^7 J\psi$ events collected with BESII at the Beijing
Electron-Positron Collider (BEPC), the decay branching fractions of
$J\psi\to\omega\pi^0$, $\omega\eta$, and $\omega\eta'$ are measured using
different $\eta$ and $\eta'$ decay modes. The results are higher than previous
measurements. The $\omega\pi^0$ electromagnetic form factor is also obtained.


title: GlueX: The Search for Gluonic Excitations at Jefferson Laboratory

abstract:
  One of the unanswered and most fundamental questions in physics regards the
nature of the confinement mechanism of quarks and gluons in quantum
chromodynamics (QCD). Exotic hybrid mesons manifest gluonic degrees of freedom
and their detailed spectroscopy will provide the precision data necessary to
test assumptions in lattice QCD and the specific phenomenology leading to
confinement. Photoproduction is expected to be a particularly effective manner
to produce exotic hybrids, however, existing data using photon beams are
sparse. At Jefferson Laboratory, plans are underway by the GlueX Collaboration
to use the coherent bremsstrahlung technique to produce a linearly polarized
photon beam. A solenoid-based hermetic detector will be used to collect data on
meson production and decays with statistics that will exceed existing
photoproduction data by several orders of magnitude after the first year of
running. In order to reach the ideal photon energy of 9 GeV required for these
studies, the energy of the Jefferson Laboratory electron accelerator, CEBAF,
will be doubled from its current maximum energy of 6 GeV to 12 GeV. The physics
motivating the search and the status of the project are reviewed.


title: Study of the decay phi--> f0(980)g --> pi+pi-g with the KLOE detector

abstract:
  We measured, with the KLOE detector, the spectrum of pi+pi- invariant mass in
a sample of 6.7 x 10^5 e+e- --> pi+pi-g events with the photon at large polar
angle (theta_g>45^o) at a centre of mass energy sqrt(s) around the phi mass. We
observe a clear contribution from the intermediate process phi --> f0(980)g. A
sizeable effect is also observed in the distribution of the forward-backeard
asymmetry. We use different theoretical models to fit the spectrum and we
determine the f_0 mass and coupling constants to the phi, to pi+pi- and to KK.


title: HERA Diffractive Structure Function Data and Parton Distributions

abstract:
  Recent diffractive structure function measurements by the H1 and ZEUS
experiments at HERA are reviewed. Various data sets, obtained using
systematically different selection and reconstruction methods, are compared.
NLO DGLAP QCD fits are performed to the most precise H1 and ZEUS data and
diffractive parton densities are obtained in each case. Differences between the
Q^2 dependences of the H1 and ZEUS data are reflected as differences between
the diffractive gluon densities.


title: The Strangeness Physics Program at CLAS

abstract:
  An extensive program of strange particle production off the proton is
currently underway with the CEBAF Large Acceptance Spectrometer (CLAS) in Hall
B at Jefferson Laboratory. This talk will emphasize strangeness photo- and
electroproduction in the baryon resonance region between W =1.6 and 2.5 GeV,
where indications of s-channel structure are suggestive of high-mass baryon
resonances coupling to kaons and hyperons in the final state. Precision
measurements of cross sections and polarization observables are being carried
out with both electron and real photon beams, both of which are available with
high polarization at energies up to 6 GeV.


title: D0 Top Physics

abstract:
  The Tevatron proton-antiproton collider at Fermilab operates at a centre of
mass energy of 1.96 TeV and is currently the only source for the production of
top quarks.
  Recent D0 results on the top quark's production cross section and its
properties such as mass, helicity of the W boson in its decay and branching
fraction B(t -> Wb) are presented, and probe the validity of the Standard
Model.


title: Recent Results in Prompt Photon Production

abstract:
  An introduction is given to recent results in prompt photon production in
different reactions.


title:
Single Spin Asymmetry of Charged Hadron Production by 40 GeV/c Polarized
  Protons

abstract:
  The single spin asymmetry for charge hadron production off nuclei (C, Cu) has
been measured using 40 GeV/c polarized proton beam.
  The measurements were carried out using FODS-2 experimental setup at
  IHEP. The data are presented in the central region and the forward region
with respect to the incident protons.


title: Precise measurement of Br($K^+ \to \pi^+ \nu \bar{\nu}$) at CERN SPS

abstract:
  An experimental proposal to measure Br($K^+ \to \pi^+ \nu \bar{\nu}$) has
been submitted at the CERN SPSC. The goal is to collect ~80 $K^+\to \pi^+ \nu
\bar{\nu}$ events with signal to background ratio of 10:1 in two years of data
taking. This will allow determination of the CKM parameter $V_{td}$ with ~10%
accuracy.


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

abstract:
  The mass of the $\tau$-lepton has been measured in the decay modes $\tau \to
3\pi \nu_\tau$ and $\tau \to 3\pi \pi^0\nu_\tau$ using a pseudomass technique.
The preliminary result is $1776.71\pm 0.25 {(stat)} \pm 0.62 {(syst)}$ MeV. The
preliminary value of an upper limit on the relative mass difference between
positive and negative $\tau$ leptons is
$|(M_{\tau^+}-M_{\tau^-})|/M_{\mathrm{average}}$ is $5.0 \times 10^{-4}$ at 90%
CL.


title: W Mass and Properties

abstract:
  Precise measurements of the mass and width of the W boson are sensitive to
radiative corrections and can be used to place limits on new physics beyond the
Standard Model and validate the consistency of the model. In particular, the W
boson mass constrains the mass of the, as yet unobserved, Higgs boson and the
width can be used to place limits on the existence of new particles that couple
to the W. Results are presented from proton anti-proton collisions recorded by
the CDF and D0 experiments at the Fermilab Tevatron collider, operating at a
centre of mass energy of 1.96 TeV. The uncertainty on the W mass is determined
to be 76 MeV by CDF and the width, by D0, to be 2011 +/- 90 (stat.) +/- 107
(syst.) MeV.


title: Violent Collisions of Spinning Protons

abstract:
  There will be a review of the history of polarized proton beams, and a
discussion of the unexpected and still unexplained large transverse spin
effects found in several high energy proton-proton spin experiments at the ZGS,
AGS and Fermilab. Next, there will be a discussion of present and possible
future experiments on the violent elastic collisions of polarized protons at
the 70 GeV U-70 accelerator at IHEP-Protvino in Russia and the new high
intensity 50 GeV J-PARC facility being built at Tokai in Japan.


title: The X(3872) at the Tevatron

abstract:
  I report results on the X(3872) from the Tevatron. Mass and other properties
have been studied, with a focus on new results on the dipion mass spectrum in X
-> J/PsiPi^+Pi^- decays. Dipions favor interpreting the decay as J/PsiRho,
implying even C-parity for the X. Modeling uncertainties do not allow
distinguishing between S- and P-wave decays of the J/PsiRho mode. Effects of
Rho-Omega interference in X decay are also introduced.


title:
Prospects for measuring coherent neutrino-nucleus elastic scattering at
  a stopped-pion neutrino source

abstract:
  Rates of coherent neutrino-nucleus elastic scattering at a high-intensity
stopped-pion neutrino source in various detector materials (relevant for novel
low-threshold detectors) are calculated. Sensitivity of a coherent
neutrino-nucleus elastic scattering experiment to new physics is also explored.


title: Bs, Bc and b-baryons

abstract:
  We present the latest measurements on masses, lifetimes and branching
fractions for the B_s and B_c mesons as well as for b-baryons. For the B_s
meson we discuss as well the latest results on mixing. These results were
produced by the CDF and D0 experiments at Fermilab or by earlier LEP and PEPII
experiments.


title: On the direct search for spin-dependent WIMP interactions

abstract:
  We examine the current directions in the search for spin-dependent dark
matter. We discover that, with few exceptions, the search activity is
concentrated towards constraints on the WIMP-neutron spin coupling, with
significantly less impact in the WIMP-proton sector. We review the situation of
those experiments with WIMP-proton spin sensitivity, toward identifying those
capable of reestablishing the balance.


title: Lepton Flavor Violation in tau decays at BaBar

abstract:
  Searches for lepton flavor violating tau -> l gamma, tau -> lll and tau ->
lhh decays at the BaBar experiment are presented. Upper limits on the branching
ratios are obtained at the level of 10^{-7} at 90% confidence level.


title: Spin physics program in the U70 polarized proton beam

abstract:
  A possibility to accelerate a high intensity polarized proton beam up to 70
GeV at the IHEP accelerator, extract it from the main ring and deliver to
several experimental setups is being studied now. We propose to study a wealth
of single- and double-spin observables in various reactions using
longitudinally and transverserly polarized proton beams at U70. The proposed
measurements can be done at the existing detectors as well as require to create
a few new experimental setups at U70.


title: Prospects for F_L^D Measurements at HERA-II

abstract:
  The theoretical interest in the longitudinal diffractive structure function
F_L^D is briefly motivated and possible measurement methods are surveyed. A
simulation based on realistic scenarios with a reduced proton beam energy at
HERA-II using the H1 apparatus shows that measurements are possible with up to
4 sigma significance, limited by systematic errors.


title: Study of Open Charm Production in p+p Collisions at $\sqrt(s)$ = 200 GeV

abstract:
  The dissertation presents the measurement of electrons from heavy flavor
decays in proton + proton collisions at RHIC at collision energy $\sqrt(s) =
200$ GeV. Two independent analysis techniques of signal extraction were
performed. This is the first measurement of the Open Charm crossection at this
collision energy and it is an important baseline measurement for comparison
with nucleus + nucleus collisions. The modification of Open Charm production in
heavy ion collisions compared to the presented p+p result can be used to study
the final state interaction of the heavy quarks with hot dense matter inside
the collisions. The results of the Open Charm measurements are compared to
current pQCD predictions both in Leading Order (LO) $O(\alpha_s^2)$ and
Next-to-Leading Order (NLO) $O(\alpha_s^3)$. The final result for the total
Open Charm crossection is $\sigma_{c\bar{c}}= (0.920 \pm 0.148(stat)\pm
0.524(sys))$ mb.


title: Measurement of the Mass and the Width of the W Boson at LEP

abstract:
  The mass and the total decay width of the W boson are measured with the L3
detector at the LEP e+e- collider using W-boson pairs produced in 0.7/fb of
data collected at centre-of-mass energies between 161 and 209GeV. Combining
semi-leptonic and fully-hadronic final states, the mass and the width of the W
boson are determined to be mW = 80.270 +/- 0.046 +/- 0.031 GeV and GW = 2.18
+/- 0.11 +/- 0.09 GeV, where the first uncertainty is statistical and the
second systematic.


title:
Multidimensional HBT correlations in proton-antiproton collisions at
  root(s) = 630 GeV

abstract:
  We analyse second moments $R_2$ of like-sign pion pairs in the
two-dimensional $(q_L,q_T)$ and three-dimensional $(q_O,q_S,q_L)$
decompositions of the three-momentum difference. Conventional fit
parametrisations such as gaussian, exponential, power-law and Edgeworth fail
miserably, while more elaborate ones such as Levy do well but fail to yield a
unique best-fit solution. A two-component model using a hard cut to separate
small- and large-scale parts appears possible but not compelling. In all cases,
the data exhibits a strong and hitherto unexplained peak at small momentum
differences which exceeds current fits.


title: Prompt Photon Production at the Tevatron

abstract:
  The DO and CDF experiments have measured prompt photon production using Run
II data taken at a centre-of-mass energy sqrt(s) of 1.96 TeV. The results are
compared to different types of perturbative QCD calculations.


title:
Measurement of the Pion and Photon Light-Cone Wave Functions by
  Diffractive Dissociation

abstract:
  The measurement of the pion light-cone wave function is revisited and results
for the Gegenbauer coefficients are presented. Mesurements of the photon
electromagnetic and hadronic wave functions are described and results are
presented.


title:
Phenomenological study of the atypical heavy flavor production observed
  at the Fermilab Tevatron

abstract:
  We address known discrepancies between the heavy flavor properties of jets
produced at the Tevatron collider and the prediction of conventional-QCD
simulations. In this study, we entertain the possibility that these effects are
real and due to new physics. We show that all anomalies can be simultaneously
fitted by postulating the additional pair production of light bottom squarks
with a 100% semileptonic branching fraction.


title:
Measurement of the Isolated Photon Cross Section in p-pbar Collisions at
  sqrt{s}=1.96 TeV

abstract:
  The cross section for the inclusive production of isolated photons has been
measured in p anti-p collisions at sqrt{s}=1.96 TeV with the D0 detector at the
Fermilab Tevatron Collider. The photons span transverse momenta 23 to 300 GeV
and have pseudorapidity |eta|<0.9. The cross section is compared with the
results from two next-to-leading order perturbative QCD calculations. The
theoretical predictions agree with the measurement within uncertainties.


title: The structure of the proton and NLO QCD fits

abstract:
  HERA has provided a wealth of high precision structure function and jet
production data, allowing considerable progress to be made in understanding the
structure of the proton. In this paper, several of the most recent proton
structure results from the H1 and ZEUS Collaborations at HERA are presented.
These include results from NLO QCD fits, neutral current deep inelastic
scattering and jet production at high transverse energy.


title:
Observation of a cusp-like structure in the pizero-pizero invariant mass
  distribution from K+- ==> pi+- pizero pizero decay and determination of the
  pi-pi scattering lengths

abstract:
  We report the results from a study of ~23 Million K+- ==> pi+- pizero pizero
decays recorded by the NA48/2 experiment at the CERN SPS, showing an anomaly in
the pizero pizero invariant mass distribution in the region around 2m+, where
m+ is the charged pion mass. This anomaly, never observed in previous
experiments, can be interpreted as an effect due mainly to the final state
charge exchange scattering process pi+ pi- ==> pizero pizero in K+- ==> pi+-
pi+ pi- decay. It provides a precise determination of a0 - a2, the difference
between the pi-pi scattering lengths in the isospin I=0 and I=2 states.


title:
A Search for the Higgs Boson using Very Forward Tracking Detectors with
  CDF

abstract:
  We propose to add high precision track detectors 55m downstream on both (E&W)
sides of CDF, to measure high Feynman-x protons and antiprotons in association
with central states. A primary motivation is to search for the Higgs boson, and
if it is seen to measure its mass precisely. The track detectors will be
silicon strip telescopes backed up by high resolution time-of-flight counters.
The addition of these small detectors effectively converts the Tevatron into a
gluon-gluon collider with sqrt{s} from 0 to ~ 200 GeV.
  This experiment will also measure millions/year clean high-|t| elastic
scattering events and produce millions of pure gluon jets. Besides a wealth of
unique QCD studies we will search for signs of exotic physics such as SUSY and
Large Extra Dimensions.


title:
Measurements of $\alpha_s$ and parton distribution functions using HERA
  jet data

abstract:
  Use of HERA jet production cross sections can extend our knowledge of the
gluon parton distribution function and yield accurate measurements of
$\alpha_s(M_Z)$ in addition to illustrating the running of $\alpha_s$ with
scale.


title: Angra Neutrino Project: status and plans

abstract:
  We present the status and plans of the Angra Project, a new nuclear reactor
neutrino oscillation experiment, proposed to be built in Brazil at the Angra
dos Reis nuclear reactor complex. This experiment is aimed to measure theta_13,
the last unknown of the three neutrino mixing angles. Combining a high
luminosity design, very low background from cosmic rays and careful control of
systematic errors at the 1% level, we propose a high sensitivity multi-detector
experiment, able to reach a sensitivity to antineutrino disappearance down to
sin^2(2*theta_13) = 0.006 in a three years running period, improving present
limits constrained by the CHOOZ experiment by more than an order of magnitude.


title:
New result on the measurement of the direct photon emission in K+ -->
  pi^+ pi^0 gamma decay

abstract:
  We present a new result on the K^+ --> pi^+ pi^0 gamma decay measurement
using stopped kaons. The best fit to the decay spectrum comprised of 10k events
gives a branching ratio for the direct photon emission of
[3.8+-0.8(stat)+-0.7(syst)] times 10^{-6} in the pi^+ kinetic energy region of
55 to 90 MeV. This result has been obtained with the assumption that there is
no component due to interference with the inner bremsstrahlung.


title: Exciting Developments in Hadron Spectroscopy

abstract:
  There has been a renaissance in hadron spectroscopy during the last couple of
years. Long lost states have been tracked down. Unexpected states are showing
up all over, and numerous measurements with unprecedented precision are being
reported. A review is presented.


title: Charmonium at CLEO

abstract:
  At CLEO, charmonium spectroscopy is pursued both thorugh e+e- annihilation
data taken in the Upsilon region and more recently at psi(2S). A nmber of first
observations (eta_c', h_c, pi and K form factors) have been made, and numerous
high precision measurements have been made in radiative and hadronic decays of
charmonium resonances. A brief report of these contributions is presented.


title: Transverse Spin at PHENIX: Results and Prospects

abstract:
  The Relativistic Heavy Ion Collider (RHIC), as the world's first and only
polarized proton collider, offers a unique environment in which to study the
spin structure of the proton. In order to study the proton's transverse spin
structure, the PHENIX experiment at RHIC took data with transversely polarized
beams in 2001-02 and 2005, and it has plans for further running with transverse
polarization in 2006 and beyond. Results from early running as well as
prospective measurements for the future will be discussed.


title: Event shapes and subjet distributions at HERA

abstract:
  Recent results on subjet distributions from ZEUS are presented. The measured
normalised cross sections were used to study the pattern of parton radiation.
The comparison of the measurements with leading-logarithm parton-shower Monte
Carlo models and perturbative QCD calculations shows a good agreement between
data and predictions. Results on event-shape mean values and distributions are
also presented. These measurements were used to test the predictions of the
power-correction model for hadronisation. A universal value, within 10%, of the
effective parameter alpha_0 of the model was obtained.


title:
Radiative Decays of the Upsilon(1S) to gamma pi^0 pi^0, and gamma eta
  eta and gamma pi^0 eta

abstract:
  We report on a study of exclusive radiative decays of the Upsilon(1S)
resonance into the final states gamma pi^0 pi^0, gamma eta eta and gamma pi^0
eta, using 1.13 inverse femto-barn of e^+ e^- annihilation data collected at
sqrt(s)= 9.46 GeV with the CLEO III detector operating at the Cornell Electron
Storage Ring. In the channel gamma pi^0 pi^0, we measure the branching ratio
for the decay mode Upsilon(1S) to gamma f_2(1270) to be (10.5 \pm 1.6 (+
1.9)(-1.8)) x 10^-5. We place upper limits on the product branching ratios for
the isoscalar resonances f_0(1500) and f_0(1710) for the pi^0 pi^0 and eta-eta
decay channels. We also set an upper limit on the Upsilon(1S) radiative decay
into pi^0 eta.


title:
Measurement of alpha_s with JADE using Moments of event shape
  observables and the Four-Jet Rate

abstract:
  Data from e+e-annihilation into hadrons collected by the JADE experiment at
centre-of-mass energies between 14 GeV and 44 GeV were used to study moments of
event shape distributions and the four-jet rate as a function of the Durham
algorithm's resolution parameter y_cut. The data were compared to a QCD NLO
order calculations and including NLLA resummation in the case of the four-jet
rate. The strong coupling measured from the moments was
alpha_s(M_Z)=0.1286+-0.0007(stat)+-0.0011(exp)+-0.0022(had)+-0.0068(theo) and
from the four-jet rate was
alpha_s(M_Z)=0.1169+-0.0004(stat)+-0.0012(exp)+-0.0021(had)+-0.0007(theo) both
in agreement with the world average.


title: The scattering of muons in low Z materials

abstract:
  This paper presents the measurement of the scattering of 172 MeV/c muons in
assorted materials, including liquid hydrogen, motivated by the need to
understand ionisation cooling for muon acceleration.
  Data are compared with predictions from the Geant 4 simulation code and this
simulation is used to deconvolute detector effects. The scattering
distributions obtained are compared with the Moliere theory of multiple
scattering and, in the case of liquid hydrogen, with ELMS. With the exception
of ELMS, none of the models are found to provide a good description of the
data. The results suggest that ionisation cooling will work better than would
be predicted by Geant 4.7.0p01.


title: Search for Leptoquarks and Compositeness at D0

abstract:
  In this paper searches are presented for the pair production of first and
second generation scalar leptoquarks and limits are given on the quark-lepton
compositeness scale from proton-antiproton collision data at a center-of-mass
energy 1.96 TeV, collected with Run II D0 Detector in 2002-2004.
  No evidence for a leptoquark signal has been observed. From the upper bounds
on the product of cross section times branching ratio beta=Br(LQ to lj), a
lower mass limits of M(LQ1) > 241 GeV and M(LQ2) > 247 GeV for the first and
second LQ generation are set for beta=1. These results, combined with those
obtained by D0 in Run I at a center-of-mass energy of 1.8 TeV, allow to exclude
scalar LQ masses up to 256 GeV and 251 GeV (for beta=1) for the first and
second generation, respectively.
  The dilepton mass spectra in pp -> l+l-+X interactions are studied using
dielectron (dimuon) data samples, corresponding to an integrated luminosity of
271 pb-1 (406 pb-1). The mass spectra being a probe for new physics are
examined for new interactions of quarks and leptons from a common composite
structure. No excess of events is found over the expectation from Standard
Model processes. The current experimental lower limits on the compositeness
scale vary, for different chirality channels, from 3.6 to 9.1 TeV for the
(eeqq) and from 4.2 to 9.8 TeV for the (mumuqq) contact interaction.


title: LHC Expectations (Machine, Detectors and Physics)

abstract:
  Starting in two years from now, particle physics will enter a new regime in
terms of energies and luminosities, thanks to the Large Hadron Collider (LHC)
at CERN. This report summarizes the status of the preparations, both for the
machine and the detectors, as of fall 2005. The commissioning and start-up
scenarios are outlined and some highlights from the very rich physics programme
are given, concentrating on measurements of Standard Model processes, as well
as on early discovery scenarios. The prospects of B-physics and heavy ion
collisions at LHC are also briefly discussed. The report concludes with an
outlook on the ultimate physics reach and on upgrade scenarios.


title: Measurements of sin2Beta at BABAR with charmonium and penguin decays

abstract:
  This article summarises measurements of time-dependent CP asymmetries in
decays of neutral B mesons to charmonium, open-charm and gluonic
penguin-dominated charmless final states. Unless otherwise stated, these
measurements are based on a sample of approximately 230 million Y(4S) to BBbar
decays collected by the BABAR detector at the PEP-II asymmetric-energy
B-factory.


title:
Measurement of the Top Quark Mass with the Dynamical Likelihood Method
  using Lepton plus Jets Events with b-tags in ppbar Collisions at s**(1/2) =
  1.96 TeV

abstract:
  This report describes a measurement of the top quark mass, M_{top}, with the
dynamical likelihood method (DLM) using the CDF II detector at the Fermilab
Tevatron. The Tevatron produces top/anti-top pairs in protons and anti-protons
collisions at a center-of-mass energy of 1.96 TeV. The data sample used in this
analysis was accumulated from March 2002 through August 2004, which corresponds
to an integrated luminosity of 318 pb^{-1}. We use the top/anti-top candidates
in the ``lepton+jets'' decay channel, requiring at least one jet identified as
a b quark by finding a displaced secondary vertex. The DLM defines a likelihood
for each event based on the differential cross section as a function of M_{top}
per unit phase space volume of the final partons, multiplied by the transfer
functions from jet to parton energies. The method takes into account all
possible jet combinations in an event, and the likelihood is multiplied event
by event to derive the top quark mass by the maximum likelihood method. Using
63 top quark candidates observed in the data, with 9.2 events expected from
background, we measure the top quark mass to be 173.2 +2.6/-2.4 (stat.) +/- 3.2
(syst.) GeV/c^2, or 173.2 +4.1/-4.0 GeV/c^2.


title:
Measurement of the transverse target-spin asymmetry associated with
  deeply virtual Compton scattering on the proton

abstract:
  Measurements of deeply virtual Compton scattering (DVCS) made at HERMES using
27.6 GeV $e^\pm$ beams and various internal polarized or unpolarized gaseous
targets are discussed. Results are reported on the transverse target-spin
asymmetry (TTSA) associated with DVCS, extracted from data accumulated in
2002-2004 with the $e^+$ beam on a transversely polarized hydrogen target. TTSA
amplitudes leading in twist and $\alpha_S$ are given as a function of $-t$,
$x_B$ and $Q^2$ in the kinematic range $|t|<0.7$ GeV$^2$, $0.03<x_B<0.35$ and
$1<Q^2<10$ GeV$^2$. Theoretical predictions based on a phenomenological model
of generalized parton distributions (GPDs) agree with the experimental results.
With additional statistics accumulated in 2005, one may constrain the $u$-quark
total angular momentum in the nucleon within this model.


title:
Expected Accuracy in a Measurement of the CKM Angle $\alpha$ Using a
  Dalitz Plot Analysis of $\boldmath B^0 \to \rho \pi$ Decays in the BTeV
  Project

abstract:
  A precise measurement of the angle $\alpha$ in the CKM triangle is very
important for a complete test of Standard Model. A theoretically clean method
to extract $\alpha$ is provided by B$^0 \to \rho \pi$ decays. Monte Carlo
simulations to obtain the BTeV reconstruction efficiency and to estimate the
signal to background ratio for these decays were performed. Finally the
time-dependent Dalitz plot analysis, using the isospin amplitude formalism for
tree and penguin contributions, was carried out. It was shown that in one year
of data taking BTeV could achieve an accuracy on $\alpha$ better than
5$^{\circ}$.


title:
Measurement and Interpretation of Fermion-Pair Production at LEP
  energies above the Z Resonance

abstract:
  This paper presents DELPHI measurements and interpretations of
cross-sections, forward-backward asymmetries, and angular distributions, for
the e+e- -> ffbar process for centre-of-mass energies above the Z resonance,
from sqrt(s) ~ 130 - 207 GeV at the LEP collider. The measurements are
consistent with the predictions of the Standard Model and are used to study a
variety of models including the S-Matrix ansatz for e+e- -> ffbar scattering
and several models which include physics beyond the Standard Model: the
exchange of Z' bosons, contact interactions between fermions, the exchange of
gravitons in large extra dimensions and the exchange of sneutrino in R-parity
violating supersymmetry.


title: Spin effects in large rapidity pi0 production at STAR

abstract:
  Measurements by the STAR collaboration of neutral pion production at large
Feynman $x$ ($x_F$) in the first polarized proton collisions at $\sqrt{s}=200$
GeV were reported previously. During the following two runs additional
statistics were acquired with an improved forward calorimeter for the $\pi^0$
cross-section and analyzing power measurements. First data from $pp$ collisions
at $\sqrt{s}=410$ GeV were taken during the RHIC run that ended in June, 2005.
  The cross section was measured at $\eta=$3.3, 3.8 and 4.0 and was found to be
consistent with next-to-leading order perturbative QCD calculations.
  The analyzing power was found to be zero at negative $x_F$ and at positive
$x_F$ up to ~0.3, then increased with increasing $x_F$. This behavior can be
described by phenomenological models including the Sivers effect, the Collins
effect or higher twist contributions in initial and final states.
  Results for the analyzing power at $\eta=$3.7 and 4.0 from all data acquired
at $\sqrt{s}=200$ GeV and the status of the analysis of the $\sqrt{s}=410$ GeV
data will be presented. Future upgrade plans and status will also be discussed.


title:
Measurement of Event Shape Variables in Deep-Inelastic Scattering at
  HERA

abstract:
  Deep-inelastic ep scattering data taken with the H1 detector at HERA and
corresponding to an integrated luminosity of 106 pb^{-1} are used to study the
differential distributions of event shape variables. These include thrust, jet
broadening, jet mass and the C-parameter. The four-momentum transfer Q is taken
to be the relevant energy scale and ranges between 14 GeV and 200 GeV. The
event shape distributions are compared with perturbative QCD predictions, which
include resummed contributions and analytical power law corrections, the latter
accounting for non-perturbative hadronisation effects. The data clearly exhibit
the running of the strong coupling alpha_s(Q) and are consistent with a
universal power correction parameter alpha_0 for all event shape variables. A
combined QCD fit using all event shape variables yields alpha_s(mZ) = 0.1198
\pm 0.0013 ^{+0.0056}_{-0.0043} and alpha_0 = 0.476 \pm 0.008 ^{+0.018}
_{-0.059}.


title: High-pT Direct-Photon Results from PHENIX

abstract:
  Direct-photon measurements in p+p and Au+Au collisions at sqrt{s_{NN}} = 200
GeV from the PHENIX experiment are presented. The p+p results are found to be
in good agreement with next-to-leading-order (NLO) perturbative QCD
calculations. Direct-photon yields in Au+Au collisions scale with the number of
inelastic nucleon-nucleon collisions and don't exhibit the strong suppression
observed for charged hadrons and neutral pions. This observation is consistent
with models which attribute the suppression of high-pT hadrons to energy loss
of quarks and gluons in the hot and dense medium produced in Au+Au collisions
at RHIC.


title: The A - dependence of rho^0 neutrinoproduction on nuclei

abstract:
  The A - dependence of rho^0 meson production in neutrino-induced reactions is
investigated for the first time, using the data obtained with SKAT bubble
chamber. The nuclear medium influence on the rho^0 total yield and inclusive
distributions (on z = E_rho/nu and Feynman x_F variables) is found to be
approximately the same as for pions. It is shown, that these distributions,
with increasing A, tend to shift toward smaller values of z and x_F, thus
indicating on an increasing role of secondary intranuclear interactions. The
predictions of a simplified model incorporating the latter are found to be in
qualitative agreement with experimental data.


title:
Coherent bremsstrahlung, boherent pair production, birefringence and
  polarimetry in the 20-170 GeV energy range using aligned crystals

abstract:
  The processes of coherent bremsstrahlung (CB) and coherent pair production
(CPP) based on aligned crystal targets have been studied in the energy range
20-170 GeV. The experimental arrangement allowed for measurements of single
photon properties of these phenomena including their polarization dependences.
This is significant as the theoretical description of CB and CPP is an area of
active theoretical debate and development. With the theoretical approach used
in this paper both the measured cross sections and polarization observables are
predicted very well. This indicates a proper understanding of CB and CPP up to
energies of 170 GeV. Birefringence in CPP on aligned crystals is applied to
determine the polarization parameters in our measurements. New technologies for
high energy photon beam optics including phase plates and polarimeters for
linear and circular polarization are demonstrated in this experiment. Coherent
bremsstrahlung for the strings-on-strings (SOS) orientation yields a larger
enhancement for hard photons than CB for the channeling orientations of the
crystal. Our measurements and our calculations indicate low photon
polarizations for the high energy SOS photons.


title: Experimental Ultra--High-Energy Cosmic Ray Physics

abstract:
  One of the most striking astrophysical phenomena today is the existence of
cosmic ray particles with energies in excess of 10^20 eV. While their presence
has been confirmed by a number of experiments, it is not clear where and how
these particles are accelerated to these energies and how they travel
astronomical distances without substantial energy loss. We are entering an
exciting new era in cosmic ray physics, with instruments now producing data of
unprecedented quality and quantity to tackle the many open questions. This
paper reviews the current experimental status of cosmic ray physics and
summarizes recent results on the energy spectrum and arrival directions of
ultra-high-energy cosmic rays.


title:
First measurement of interference fragmentation on a transversely
  polarized hydrogen target

abstract:
  The HERMES experiment has measured for the first time single target-spin
asymmetries in semi-inclusive two-pion production using a transversely
polarized hydrogen target. These asymmetries are related to the product of two
unknowns, the transversity distribution function and the interference
fragmentation function. In the invariant mass range 0.51 GeV < M_inv < 0.97 GeV
the measured asymmetry deviates significantly from zero, indicating that
two-pion semi-inclusive deep-inelastic scattering can be used to probe
transversity.


title:
Measurement of the Inclusive Jet Cross Section in ppbar Interactions at
  sqrt{s}=1.96 TeV Using a Cone-based Jet Algorithm

abstract:
  We present a measurement of the inclusive jet cross section in ppbar
interactions at sqrt{s}=1.96 TeV using 385 pb^{-1} of data collected with the
CDF II detector at the Fermilab Tevatron. The results are obtained using an
improved cone-based jet algorithm (Midpoint). The data cover the jet transverse
momentum range from 61 to 620 GeV/c, extending the reach by almost 150 GeV/c
compared with previous measurements at the Tevatron. The results are in good
agreement with next-to-leading order perturbative QCD predictions using the
CTEQ6.1M parton distribution functions.


title:
Proposal of Direct Search for Strongly Bound States of ppbar, npbar
  Systems with High Intensity and Collective pbar beam

abstract:
  In this letter, we discuss the possibility to look for the direct evidence of
the existence of the ppbar and npbar bound states. Measurement of the single
\gamma ray from the ppbar and npbar systems at rest can directly confirm
whether the X(1860) and X(1835) are the resonances which are strongly coupled
to ppbar. In addition to the neutral candidate, a charged resonance $X^-$ is
also proposed to be searched for in npbar channel. We find that the data from
the Crystal Barrel experiment at LEAR/CERN can be used to confirm the X(1835)
observed by BES Collaboration. The possibility of measuring the $\gamma$
spectrum below 100 MeV at the new experiment with cold high intensity $\pbar$
beam at GSI is discussed. These new techniques can be used to probe the
structure of the X(1860) and X(1835) in the future.


title: PVLAS: probing vacuum with polarized light

abstract:
  The PVLAS experiment operates an ellipsometer which embraces a
superconducting dipole magnet and can measure ellipticity and rotation induced
by the magnetic field onto linearly polarized light. The sensitivity of the
instrument is about 10-7rad Hz-1/2. With a residual pressure less than 10-7mbar
the apparatus gives both ellipticity and rotation signals at the 10-7rad level
with more than 8 sigma sob ratio in runs that last about 1000sec. These signals
can be interpreted as beeing generated largely by vacuum ellipticity and
dichroism induced by the transverse magnetic field.If this interpretation is
correct, a tool has become available to characterize physical properties of
vacuum as if it were an ordinary transparent medium. A microscopic effect
responsible for this induced dichroism could be the existence of ultralight
spin zero bosons with mass of the order of 10-3eV, that would couple to two
photons and would be created in the experiment by interaction of photons of the
laser beam with virtual photons of the magnetic field. The inverse of the
coupling constant to two photons would correspond to a mass M of the order of
10+6GeV.


title: A study of e+e- -> p anti-p using initial state radiation with BABAR

abstract:
  The e+e- -> p anti-p cross section is determined over a range of p anti-p
masses, from threshold to 4.5 GeV/c^2, by studying the e+e- -> p anti-p gamma
process. The data set corresponds to an integrated luminosity of 232 fb^-1,
collected with the BABAR detector at the PEP-II storage ring, at an e+e-
center-of-mass energy of 10.6 GeV. The mass dependence of the ratio of electric
and magnetic form factors, |G_E/G_M|, is measured for p anti-p masses below 3
GeV/c^2; its value is found to be significantly larger than 1 for masses up to
2.2 GeV/c^2. We also measure J/psi -> p anti-p and psi(2S) -> p anti-p
branching fractions and set an upper limit on Y(4260) -> p anti-p production
and decay.


title: Branching fractions of B-->h+h'- modes at CDF

abstract:
  I report the analysis of B-->h+h'- decays (where h and h' denote K or pi), in
180 pb-1 of proton-antiproton collisions at s**0.5= 1.96 TeV, with the CDF II
detector at the Tevatron Collider. A B-->h+h'- signal was reconstructed at a
hadron collider for the first time, in the sample collected by the dedicated
trigger on long-lived decays. With about 900 signal events, we observed the new
mode Bs-->K+K-, and we measured its branching fraction relative to the
B0-->K+pi- mode: (f_s/f_d)*BR(Bs-->K+K-)/BR(B0-->K+pi-)=0.46 +/- 0.08 (stat.)
+/- 0.07 (syst.); we also measured the CP-violating decay-rate asymmetry for
the B0-->K+pi- mode: ACP=-0.013 +/- 0.078 (stat.) +/- 0.012 (syst.). Since we
did not find evidence for rarer modes, we set the following 90% C.L. upper
limits on the decay rates: (f_s/f_d)*BR(Bs-->K-pi+)/BR(B0-->K+pi-)<0.08 and
BR(Bs-->pi+pi-)/BR(Bs-->K+K-)< 0.05 that are greatly improved with respect to
current world averages.


title:
Experimental study of $\psi(2S)$ decays to $\K^+ K^- \pi^+ \pi^- \pi^0$
  final states

abstract:
  $K^+K^-\pi^+\pi^-\pi^0$ final states are studied using a sample of
$14\times10^6$ $\psi(2S)$ decays collected with the Beijing Spectrometer
(BESII) at the Beijing Electron-Position Collider. The branching fractions of
$\psi(2S)$ decays to $ K^+K^-\pi^+\pi^-\pi^0$, $\omega K^+ K^-$, $\omega
f_0(1710)$, $ K^{\ast}(892)^0 K^- \pi^+\pi^0+c.c.$, $K^{\ast}(892)^{+} K^-
\pi^+\pi^- +c.c.$, $K^{\ast}(892)^{+} K^- \rho^0+c.c.$ and $K^{\ast}(892)^0
K^-\rho^+ + c.c.$ are determined. The first two agree with previous
measurements, and the last five are first measurements.


title: Low Energy Antiproton Experiments -- A Review

abstract:
  Low energy antiprotons offer excellent opportunities to study properties of
fundamental forces and symmetries in nature. Experiments with them can
contribute substantially to deepen our fundamental knowledge in atomic, nuclear
and particle physics. Searches for new interactions can be carried out by
studying discrete symmetries. Known interactions can be tested precisely and
fundamental constants can be extracted from accurate measurements on free
antiprotons ($\bar{p}$'s) and bound two- and three-body systems such as
antihydrogen ($\bar{{\rm H}}=\bar{p}e^-$), the antprotonic helium ion (He$^{++}
\bar{p}$)$^+$ and the antiprotonic atomcule (He$^{++} \bar{p}e^-$) . The
trapping of a single $\bar{p}$ in a Penning trap, the formation and precise
studies of antiprotonic helium ions and atoms and recently the production of
$\bar{{\rm H}}$ have been among the pioneering experiments. They have led
already to precise values for $\bar{p}$ parameters, accurate tests of bound
two- and three-body Quantum Electrodynamics (QED), tests of the CPT theorem and
a better understanding of atom formation from their constituents. Future
experiments promise more precise tests of the standard theory and have a robust
potential to discover new physics.


title:
New results on e+e- -> hadrons exclusive cross sections from experiments
  with SND detector at VEPP-2M e+e- collider in the energy range
  sqrt(s)=0.4-1.4 GeV

abstract:
  New results of the e+e- -> pi+pi-, K+K-, K_SK_L, pi0/gamma, eta0/gamma
processes cross section measurements are presented. The results are based on
the 30 pb^-1 data, accumulated by SND detector at VEPP-2M e+e- collider in the
energy range sqrt(s)=0.4-1.4 GeV during 1995-2000 years. The comparison with
existing experimental data shows that the measurement accuracy is close to or
better than the world average. For the e+e- -> pi+pi- process the accuracy is
about 0.01. This is important for calculation of hadronic contribution into the
muon anomalous magnetic moment.


title: Search for rare quark-annihilation decays, B --> Ds(*) Phi

abstract:
  We report on searches for B- --> Ds- Phi and B- --> Ds*- Phi. In the context
of the Standard Model, these decays are expected to be highly suppressed since
they proceed through annihilation of the b and u-bar quarks in the B- meson.
Our results are based on 234 million Upsilon(4S) --> B Bbar decays collected
with the BABAR detector at SLAC. We find no evidence for these decays, and we
set Bayesian 90% confidence level upper limits on the branching fractions BF(B-
--> Ds- Phi) < 1.9x10^(-6) and BF(B- --> Ds*- Phi)<1.2x10^(-5). These results
are consistent with Standard Model expectations.


title:
Measurement of the J/Psi Production Cross Section in 920 GeV/c
  Fixed-Target Proton-Nucleus Interactions

abstract:
  The mid-rapidity (dsigma_(pN)/dy at y=0) and total sigma_(pN) production
cross sections of J/Psi mesons are measured in proton-nucleus interactions.
Data collected by the HERA-B experiment in interactions of 920 GeV/c protons
with carbon, titanium and tungsten targets are used for this analysis. The
J/Psi mesons are reconstructed by their decay into lepton pairs. The total
production cross section obtained is sigma_(pN)(J/Psi) = 663 +- 74 +- 46
nb/nucleon. In addition, our result is compared with previous measurements.

Improved Measurement of the b-bbar Production Cross Section in 920 GeV
  Fixed-Target Proton-Nucleus Collisions

abstract:
  A new measurement of the b-bbar production cross section in 920 GeV
proton-nucleus collisions is presented by the HERA-B collaboration. The b-bbar
production is tagged via inclusive bottom quark decays into J/psi mesons, by
exploiting the longitudinal separation of J/psi->ll decay vertices from the
primary proton-nucleus interaction point. Both e+e- and mu+mu- channels are
reconstructed, for a total of 83 +- 12 inclusive b->J/psi X events found. The
combined analysis yields a b-bbar to prompt J/psi cross section ratio of
${\frac{{\Delta\sigma(bbbar)}}{{\Delta\sigma_{\jpsi}}}} = 0.032\pm 0.005 \stat
\pm 0.004 \sys$ measured in the x_f acceptance (-0.35 <x_f <0.15), extrapolated
to $\sigma(bbbar) = 14.9 \pm 2.2 \stat \pm 2.4 \sys $ nb/nucleon in the total
phase space.


title: Search for the Rare Decays B0 -> Ds(*)+ a0(2)-

abstract:
  We have searched for the decays $B^0 \rightarrow D_s^{+}a_0^-$, $B^0
\rightarrow D_s^{*+}a_0^-$, $B^0 \rightarrow D_s^{+}a_2^-$ and $B^0 \rightarrow
D_s^{*+}a_2^-$ in a sample of about 230 million $\Upsilon(4S) \rightarrow
B{\bar B}$ decays collected with the {\sl BaBar} detector at the PEP-II
asymmetric-energy $B$-factory at SLAC. We find no evidence for these decays and
set upper limits at 90\% C.L. on the branching fractions: ${\cal B}(B^0
\rightarrow D_s^+ a_0^-) < 1.9\times 10^{-5}$, ${\cal B}(B^0 \rightarrow
D_s^{*+} a_0^-) < 3.6\times 10^{-5}$, ${\cal B}(B^0 \rightarrow D_s^+ a_2^-) <
1.9 \times 10^{-4}$, and ${\cal B}(B^0 \rightarrow D_s^{*+} a_2^-) < 2.0\times
10^{-4} $.


title:
Strangeness contribution to the vector and axial form factors of the
  nucleon

abstract:
  The strangeness contribution to the vector and axial form factors of the
nucleon is presented for momentum transfers in the range $0.45<Q^2<1.0$
GeV$^2$. The results are obtained via a combined analysis of forward-scattering
parity-violating elastic $\vec{e}p$ asymmetry data from the $G^0$ and HAPPEx
experiments at Jefferson Lab, and elastic $\nu p$ and $\bar{\nu} p$ scattering
data from Experiment 734 at Brookhaven National Laboratory. The
parity-violating asymmetries measured in elastic $\vec{e}p$ scattering at
forward angles establish a relationship between the strange vector form factors
$G_E^s$ and $G_M^s$, with little sensitivity to the strange axial form factor
$G_A^s$. On the other hand, elastic neutrino scattering at low $Q^2$ is
dominated by the axial form factor, with still some significant sensitivity to
the vector form factors as well. The combination of the two data sets allows
the simultaneous extraction of $G_E^s$, $G_M^s$, and $G_A^s$ over a significant
range of $Q^2$ for the very first time.


title:
Measurement of the Vector and Tensor Polarisation of Proton and Deuteron
  Beams

abstract:
  Measurement of the d + d -> 4He + eta reaction using vector and tensor
polarised beam has been performed at COSY using Big Karl magnetic spectrograph.
The beam polarisation necessary for obtaining the vector and tensor analysing
power for this reaction was measured. The method and the results of the tensor
polarisation measurement of the deuteron beam are presented.


title: Evidence for the decay $\Upsilon(4S) \to \Upsilon(1S) \pi^{+} \pi^{-} $

abstract:
  A study of transitions between $\Upsilon$ states with the emission of charged
pions using 398 fb$^{-1}$ of data collected with the Belle detector at the KEKB
asymmetric energy $e^+e^-$ collider is presented. A clear peak from the decay
$\Upsilon(1S)\to\mu^+\mu^-$ is observed in the invariant mass distribution of
$(\mu^+ \mu^-)$ pairs from the $(\mu^+ \mu^- \pi^+ \pi^- X)$ event sample. The
mass difference distribution ($M_{\mu^+\mu^-\pi^+\pi^-}-M_{\mu^+\mu^-}$) for
$M_{\mu^+\mu^-}$ from the $\Upsilon(1S)$ mass region has two peaks from
$\Upsilon(2S,3S)\to \Upsilon(1S)\pi^+\pi^-$ decays, with no background. A third
peak at $\Delta M = (1119.0\pm 1.4)$~MeV/$c^2$ can be interpreted as evidence
of a signal from the decay $\Upsilon(4S)\to \Upsilon(1S)\pi^+\pi^-$ with a
subsequent $ \Upsilon(1S) \to \mu^+ \mu^-$ transition. This is the first
example of a non-$B \bar{B}$ decay of the $\Upsilon(4S)$ resonance. The
preliminary estimated branching fraction is equal to
$\mathcal{B}(\Upsilon(4S)\to \Upsilon(1S)\pi^+\pi^-) = (1.1 \pm
0.2(\mathrm{stat.}) \pm 0.4(\mathrm{sys.}))\times 10^{-4}.$


title:
Observation of a chi'_(c2) candidate in gamma gamma --> D Dbar
  production at Belle

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


title:
First Observations of Separated Atmospheric Muon Neutrino and Muon
  Anti-Neutrino Events in the MINOS Detector

abstract:
  The complete 5.4 kton MINOS far detector has been taking data since the
beginning of August 2003 at a depth of 2070 meters water-equivalent in the
Soudan mine, Minnesota. This paper presents the first MINOS observations of
muon neutrino and muon anti-neutrino charged-current atmospheric neutrino
interactions based on an exposure of 418 days. The ratio of upward to
downward-going events in the data is compared to the Monte Carlo expectation in
the absence of neutrino oscillations giving:
  R_data(up/down)/R_MC(up/down) = 0.62^{+0.19}_{-0.14} (stat.) +- 0.02 (sys.).
  An extended maximum likelihood analysis of the observed L/E distributions
excludes the null hypothesis of no neutrino oscillations at the 98 % confidence
level. Using the curvature of the observed muons in the 1.3 T MINOS magnetic
field muon neutrino and muon anti-neutrino interactions are separated. The
ratio of muon neutrino to muon anti-neutrino events in the data is compared to
the Monte Carlo expectation assuming neutrinos and anti-neutrinos oscillate in
same manner giving:
  R_data(numubar/numu)/R_MC(numubar/numu) = 0.96^{+0.38}_{-0.27} (stat.) +-
0.15 (sys.), where the errors are the statistical and systematic uncertainties.
Although the statistics are limited, this is the first direct observation of
atmospheric neutrino interactions separately for muon neutrinos and muon
anti-neutrinos.


title: Search for Anomalous Couplings in Top Decay at Hadron Colliders

abstract:
  We present a quantitative study on sensitivities to the top-decay anomalous
couplings, taking into account realistic experimental conditions expected at
Tevatron and LHC. A double angular distribution of W and charged lepton in the
top decay is analyzed, using ttbar events in the lepton+jets channel. In order
to improve sensitivities to the anomalous couplings, we apply two techniques:
(1) We use a likelihood fitting method for full kinematical reconstruction of
each top event. (2) We develop a new effective spin reconstruction method for
leptonically-decayed top quarks; this method does not require spin information
of the antitop side. For simplicity, we neglect couplings of right-handed
bottom quark as well as CP violating couplings. The 95% C.L. estimated bound on
a ratio of anomalous couplings reads -0.81 < f_2/f_1 < -0.70,
-0.12<f_2/f_1<0.14 using 1000 reconstructed top events at Tevatron, while
-0.74<f_2/f_1<-0.72, -0.01<f_2/f_1<0.01 is expected with 100k reconstructed top
events at LHC, where only statistical errors are taken into account. A two-fold
ambiguity in the allowed range remains when the number of events exceeds a few
hundred.


title:
Measurement of sigma(e^+e^- --> psi(3770) --> hadrons) at E_{cm}=3773
  MeV

abstract:
  We measure the cross section for e^+e^- -> \psi(3770) -> hadrons at Ecm=3773
MeV to be (6.38+-0.08^{+0.41}_{-0.30}) nb using the CLEO detector at the CESR
e^+e^- collider. The difference between this and the e^+e^- -> \psi(3770) ->
DD-bar cross section at the same energy is found to be
(-0.01+-0.08^{+0.41}_{-0.30}) nb. With the observed total cross section, we
extract \Gamma_ee(\psi(3770))=(0.204+-0.003^{+0.041}_{-0.027}) keV.
Uncertainties shown are statistical and systematic, respectively.


title: Charmonium from CLEO

abstract:
  At CLEO, the charmonium singlet states eta_c(2 1S0) and h_c(1 1P1) have been
firmly identified and a long standing discrepancy for Gamma_(gamma
gamma)(chi_c2) has been resolved.


title:
Measurement of the double longitudinal spin asymmetry in inclusive jet
  production in polarized p+p collisions at sqrt(s) = 200 GeV

abstract:
  We present preliminary results for the first measurements of the double
longitudinal spin asymmetry A_LL in inclusive jet production at mid-rapidity in
polarized proton-proton collisions at sqrt(s) = 200 GeV. The data amount to ~
0.5 pb-1 collected at RHIC in 2003 and 2004 with beam polarizations up to 45%.
The jet transverse energies are in the range of 5 < pT < 17 GeV/c. The data are
consistent with theoretical evaluations using deep-inelastic scattering
parametrizations for gluon polarization in the nucleon, and tend to disfavor
large positive values of gluon polarization.

  Results from the K2K experiment and status of the T2K experiment are
reported.


title: Discovery Potential of MSSM Higgs Bosons with ATLAS

abstract:
  In this article the potential of the ATLAS experiment to discover MSSM Higgs
bosons is discussed. Various Monte-Carlo studies for SM Higgs boson production
and dedicated MSSM Higgs boson analyses are taken into account to investigate
the discovery potential in four different CP-conserving MSSM benchmark
scenarios, the Mh-max scenario, the no mixing scenario, the gluophobic scenario
and the small alpha scenario. The most recent theoretical calculations are used
for the prediction of Higgs masses and couplings. The results are shown for
integrated luminosities of 30 and 300 inverse fb. With 300 inverse fb, a five
sigma discovery of at least one Higgs boson state is possible in all scenarios
for all values of tan beta and MA. The heavy neutral and charged Higgs states
can only be discovered in parts of the parameter space.


title: Tests of the Electroweak Sector of the Standard Model

abstract:
  The Electroweak sector of the Standard Model is reviewed and best fits are
presented for its free parameters based on currently available experimental
tests. The Standard Model remains an excellent descriptions of the available
experimental data. The preferred mass range of the still elusive Higgs boson in
the Standard Model is $114<m_{\mathrm{H}}<219$ GeV at the 95% Confidence Level.
A Standard Model Higgs in this mass range is likely to be observed in the years
2007--2010, either at the Tevatron or at the LHC.


title: Rare Kaon Decays

abstract:
  Recent results in and future prospects for the study of rare kaon decays are
reviewed.


title: Search for RPV Scalar Leptons at Tevatron

abstract:
  We reviewed CDF and D0 searches for R-parity violation supersymmetry in
leptons involved final states using up to 344+-21 pb-1 Tevatron Run II data of
ppbar collisions at sqrt{s} = 1.96 TeV. All the results were in good agreement
with the standard model expectations. No evidence of new physics was observed.
However, owing to the improvement on detectors, energy and luminosity from Run
I to Run II, the limits for the existence of R-parity violation supersymmetry
have been greatly advanced.


title:
Measurement of Gamma_ee(J/psi), Gamma_tot(J/psi), and
  Gamma_ee[psi(2S)]/Gamma_ee(J/psi)

abstract:
  Using data acquired with the CLEO detector at the CESR e+e- collider at
sqrt{s} = 3.773 GeV, we measure the cross section for the radiative return
process e+e- --> gamma J/psi, J/psi --> mu+mu-, resulting in B(J/psi -->
mu+mu-) x Gamma_ee(J/psi) = 0.3384 +- 0.0058 +- 0.0071 keV, Gamma_ee(J/psi) =
5.68 +- 0.11 +- 0.13 keV, and Gamma_tot(J/psi) = 95.5 +- 2.4 +- 2.4 keV, in
which the errors are statistical and systematic, respectively. We also
determine the ratio Gamma_ee[psi(2S)] / Gamma_ee(J/psi) = 0.45 +- 0.01 +- 0.02.


title: D+ to mu+nu and fD+ from 281 pb-1 at Psi(3770) from CLEO-c

abstract:
  We report improved measurements of branching fraction and decay constant fD+
in D+ to mu+nu using 281 pb-1 of data taken on the Psi(3770) resonance with the
CLEO-c detector. We extract a relatively precise value for the decay constant
of the D+ meson by measuring Br(D+ to mu+nu) = (4.40+-0.66+0.09-0.12)x10^-4 and
find fD+ = (222.6+-16.7+2.8-3.4) MeV. We also set 90% confidence upper limit on
Br(D+ to e+nu) < 2.4x10^-5 which limits contributions from non-Standard Model
physics.


title: Measurement of the CKM angle alpha with the B-factories

abstract:
  B-meson decays involving b->u transitions are sensitive to the Unitarity
Triangle angle alpha (or phi_2). The B-factories at SLAC and KEK have made
significant progress toward the measurement of alpha in recent years. This
paper summarizes the results of the B-factories' constraints on alpha.


title:
Hadronic branching fractions and DDbar cross-sections at Psi(3770) from
  CLEO-c

abstract:
  We present some recent results in hadronic decays and cross-section
measurements at Psi(3770) from CLEO collaboration. They include measurement of
absolute hadronic branching fractions of D mesons and e+e- to DDbar
cross-sections, inclusive production of eta, eta', phi in D decays, branching
fractions of D+ to K0_{S,L} pi+ and eta pi+, Psi(3770) non-DDbar decays, and
timelike electromagnetic form factors of pion, kaon and proton. These results
are based on 55.8 pb-1 and 281 pb-1 at Psi(3770), and other data samples
collected by the CLEO-c detector at the Cornell Electron Storage Ring (CESR).


title:
Precision Measurements of the Charged Pion, Charged Kaon, and Proton
  Electromagnetic Form Factors at s = 13.48 GeV^2

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 transfers of |Q^2| = 13.48 GeV^2 by the reaction e+e- -> 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:
Search for Higgs Boson Decaying to b-bbar and Produced in Association
  with W Bosons in p-pbar Collisions at sqrt{s}=1.96 TeV

abstract:
  We present a search for Higgs bosons decaying into b-bbar and produced in
association with W bosons in p-pbar collisions at sqrt{s}=1.96 TeV. This search
uses 320 pb-1 of the dataset accumulated by the upgraded Collider Detector at
Fermilab. Events are selected that have a high-transverse momentum electron or
muon, missing transverse energy, and two jets, one of which is consistent with
a hadronization of a b quark. Both the number of events and the dijet mass
distribution are consistent with standard model background expectations, and we
set 95% confidence level upper limits on the production cross section times
branching ratio for the Higgs boson or any new particle with similar decay
kinematics. These upper limits range from 10 pb for mH=110 GeV/c2 to 3 pb for
mH=150 GeV/c2.


title: Form Factor Fit for e^+e^- to pi^+pi^-pi^+pi^-

abstract:
  The cross section of e^+e^- to pi^+pi^-pi^+pi^- has been measured by BABAR
collaboration. We apply the theoretical cross section deduced from the extended
VMD (VectorMeson Dominance) model to fit these experimental data. The relevant
parameters and the isovector form factor are obtained


title:
The gamma + p to K+ + Lambda and gamma + p to K+ + Sigma0 reactions at
  forward angles with photon energies from 1.5 to 2.4 GeV

abstract:
  Differential cross sections and photon beam asymmetries for the gamma p
rightarrow K+ Lambda and gamma p rightarrow K+ Sigma0 reactions have been
measured in the photon energy range from 1.5 GeV to 2.4 GeV and in the angular
range from Theta_{cm} = 0 to 60 of the K+ scattering angle in the center of
mass system at the SPring-8/LEPS facility. The photon beam asymmetries for both
the reactions have been found to be positive and to increase with the photon
energy. The measured differential cross sections agree with the data measured
by the CLAS collaboration at cosTheta_{cm}<0.9 within the experimental
uncertainties, but the discrepancy with the SAPHIR data for the K+Lambda
reaction is large at cosTheta_{cm}>0.9. In the K+Lambda reaction, the
resonance-like structure found in the CLAS and SAPHIR data at W=1.96 GeV is
confirmed. The differential cross sections at forward angles suggest a strong
K-exchange contribution in the t-channel for the K+Lambda reaction, but not for
the K+Sigma0 reaction.


title: Search for Gauginos and Gauge Mediated SUSY Breaking Scenarios at LEP

abstract:
  Data collected by the OPAL detector at LEP up to the highest energies of 209
GeV are analyzed to search for evidence of supersymmetric (SUSY) particle
production. Chargino pair-production and neutralino associated production are
considered in models where supersymmetry breaking is mediated by gravitational
interactions. The focus of the searches is on topologies arising when scalar
fermions are heavy and the lightest neutralino is the lightest SUSY particle
(LSP). Searches for topologies predicted by gauge-mediated SUSY breaking (GMSB)
models are also discussed. In these models the LSP is the gravitino and the
phenomenology is driven by the nature of the next-to-lightest SUSY particle
(NLSP) which is either the lightest neutralino, stau or mass degenerate
sleptons. As the NLSP decay length is effectively unconstrained, all possible
values are considered and results independent of the NLSP lifetime are
presented for all relevant final states including direct NLSP pair-production
and NLSP production via cascade decays of heavier SUSY particles. None of the
searches shows evidence for SUSY particle production. Cross-section limits are
presented at the 95% confidence level both for direct NLSP production and, for
the first time, also for cascade decays. These are then interpreted in the
framework of minimal theoretical models. Large areas of the accessible
parameter space are excluded and constraints on the mass of the SUSY particles
are derived.


title:
Search for Second-Generation Scalar Leptoquarks in $\bm{p \bar{p}}$
  Collisions at $\sqrt{s}$=1.96 TeV

abstract:
  Results on a search for pair production of second generation scalar
leptoquark in $p \bar{p}$ collisions at $\sqrt{s}$=1.96 TeV are reported. The
data analyzed were collected by the CDF detector during the 2002-2003 Tevatron
Run II and correspond to an integrated luminosity of 198 pb$^{-1}$. Leptoquarks
(LQ) are sought through their decay into (charged) leptons and quarks, with
final state signatures represented by two muons and jets and one muon, large
transverse missing energy and jets. We observe no evidence for $LQ$ production
and derive 95% C.L. upper limits on the $LQ$ production cross sections as well
as lower limits on their mass as a function of $\beta$, where $\beta$ is the
branching fraction for $LQ \to \mu q$.


title: Di-electron Widths of the Upsilon(1S,2S,3S) Resonances

abstract:
  We determine the di-electron widths of the Upsilon(1S), Upsilon(2S), and
Upsilon(3S) resonances with better than 2% precision by integrating the
cross-section of e+e- -> Upsilon over the e+e- center-of-mass energy. Using
e+e- energy scans of the Upsilon resonances at the Cornell Electron Storage
Ring and measuring Upsilon production with the CLEO detector, we find
di-electron widths of 1.354 +- 0.004 (stat) +- 0.020 (syst) keV, 0.619 +- 0.004
+- 0.010 keV, and 0.446 +- 0.004 +- 0.007 keV for the Upsilon(1S), Upsilon(2S),
and Upsilon(3S), respectively.


title: Physics and Detectors at the LHC and the SLHC

abstract:
  The capabilities of the ATLAS and CMS detectors being prepared for the LHC
are reviewed. Examples of physics signals accessible during early running and
during mature high luminosity LHC operation are examined. The planning and
options for the LHC and these detectors to increase the luminosity to
10^{35}cm^{-2}s^{-1} is presented. This upgrade, entitled the Super LHC (SLHC),
would occur in the next decade. The resulting physics scope is discussed.


title:
Measurements of $\Lambda$ and $\bar \Lambda$ polarization in
  longitudinally polarized proton-proton collisions at $\sqrt s$ =200 GeV at
  STAR

abstract:
  Preliminary results for the longitudinal polarization of $\Lambda$ and ${\bar
\Lambda}$ hyperons in longitudinally polarized proton-proton collisions at
$\sqrt s$ = 200 GeV are presented. The $\Lambda$($\bar \Lambda$) candidates are
reconstructed at mid-rapidity ($|\eta|<1$) with the time projection chamber of
the STAR experiment at RHIC, using 0.5 pb$^{-1}$ collected in 2003 and 2004
with beam polarizations of up to 45%. Their mean longitudinal momentum fraction
$x_F$ is about 8 $\times$$10^{-3}$ and their mean transverse momentum $p_T$ is
about 1.5 GeV. The analysis uses asymmetries of counts for different spin
states of the colliding proton beams and does not require detailed knowledge of
the detector acceptance. The preliminary $\Lambda$(${\bar \Lambda}$)
polarization values are consistent with zero within their statistical
uncertainties of 0.05.


title: Search for the Invisible Decay of Neutrons with KamLAND

abstract:
  The Kamioka Liquid scintillator Anti-Neutrino Detector (KamLAND) is used in a
search for single neutron or two neutron intra-nuclear disappearance that would
produce holes in the $\it{s}$-shell energy level of $^{12}$C nuclei. Such holes
could be created as a result of nucleon decay into invisible modes ($inv$),
e.g. $n \to 3\nu$ or $nn \to 2\nu$. The de-excitation of the corresponding
daughter nucleus results in a sequence of space and time correlated events
observable in the liquid scintillator detector. We report on new limits for
one- and two-neutron disappearance: $\tau(n\to inv)> 5.8\times 10^{29}$ years
and $\tau (nn \to inv)> 1.4 \times 10^{30}$ years at 90% CL. These results
represent an improvement of factors of $\sim$3 and $>10^4$ over previous
experiments.


title:
First Measurement of Charged Current Cross Sections at HERA with
  Longitudinally Polarised Positrons

abstract:
  Data taken with positrons of different longitudinal polarisation states in
collision with unpolarised protons at HERA are used to measure the total cross
sections of the charged current process, e^+ p \to \bar{\nu}X, for negative
four-momentum transfer squared Q^2 > 400 GeV^2 and inelasticity y<0.9. Together
with the corresponding cross section obtained from the previously published
unpolarised data, the polarisation dependence of the charged current cross
section is measured for the first time at high Q^2 and found to be in agreement
with the Standard Model prediction.


title:
Measurement of the Direct Photon Momentum Spectrum in Upsilon(1S),
  Upsilon(2S), and Upsilon(3S) Decays

abstract:
  Using data taken with the CLEO III detector at the Cornell Electron Storage
Ring, we have investigated the direct photon spectrum in the decays Upsilon(1S)
-> gggamma, Upsilon(2S) -> gggamma, Upsilon}(3S) -> gggamma. The latter two of
these are first measurements. Our analysis procedures differ from previous ones
in the following ways: a) background estimates (primarily from pi^0 decays are
based on isospin symmetry rather than a determination of the pi^0 spectrum,
which permits measurement of the Upsilon(2S) and Upsilon(3S) direct photon
spectra without explicit corrections for pi^0 backgrounds from, e.g., chi_bJ
states, b) we estimate the branching fractions with a parametrized functional
form (exponential) used for the background, c) we use the high-statistics
sample of Upsilon(2S) -> pi+ pi- Upsilon(1S) to obtain a tagged-sample of
Upsilon(1S) -> gamma + X events, for which there are no QED backgrounds. We
determine values for the ratio of the inclusive direct photon decay rate to
that of the dominant three-gluon decay Upsilon -> ggg
(R_gamma=B(gggamma)/B(ggg)) to be: R_gamma(1S)=(2.70+/-0.01+/-0.13+/-0.24)%,
R_gamma(2S)=(3.18+/-0.04+/-0.22+/-0.41)%, and
R_gamma(3S)=(2.72+/-0.06+/-0.32+/-0.37)%, where the errors shown are
statistical, systematic, and theoretical model-dependent, respectively. Given a
value of Q^2, one can estimate a value for the strong coupling constant
alpha_s(Q^2) from R_gamma.


title:
Measurement of the Inclusive Jet Cross Section using the Kt algorithm in
  pp-bar Collisions at sqrt(s) = 1.96 TeV

abstract:
  We report on a measurement of the inclusive jet production cross section in
pp-bar collisions at sqrt{s} = 1.96 TeV using data collected with the upgraded
Collider Detector at Fermilab in Run II (CDF II) corresponding to an integrated
luminosity of 385 pb^-1. Jets are reconstructed using the kt algorithm. The
measurement is carried out for jets with rapidity 0.1 < | yjet | < 0.7 and
transverse momentum in the range 54 < ptjet < 700 GeV/c. The measured cross
section is in good agreement with next-to-leading order perturbative QCD
predictions after the necessary non-perturbative parton-to-hadron corrections
are included.


title: New Measurements of Cabibbo-Suppressed Decays of D Mesons in CLEO-c

abstract:
  Using 281 pb^-1 of data collected with the CLEO-c detector, we report on
first observations and new measurements of Cabibbo-suppressed decays of D
mesons to 2, 3, 4, and 5 pions. Branching fractions of previously unobserved
modes are measured to be: B(D^0\to
pi^+pi^-pi^0pi^0)=(9.9\pm0.6\pm0.7\pm0.2\pm0.1)x10^-3,
B(D^0\to\pi^+\pi^+\pi^-\pi^-\pi^0)=(4.1\pm0.5\pm0.2\pm0.1\pm0.0)x10^-3,
B(D^+\to\pi^+\pi^0\pi^0)=(4.8\pm0.3\pm0.3\pm0.2)x10^-3,
B(D^+\to\pi^+\pi^+\pi^-\pi^0)=(11.6\pm0.4\pm0.6\pm0.4)x10^-3,
B(D^0\to\eta\pi^0)=(0.62\pm0.14\pm0.05\pm0.01\pm0.01)x10^-3, and
B(D^0\to\omega\pi^+\pi^-)=(1.7\pm0.5\pm0.2\pm0.0\pm0.0)x10^-3. The
uncertainties are from statistics, experimental systematics, normalization and
CP correlations (for D^0 modes only). Improvements in other multi-pion decay
modes are also presented. The D-->pi pi rates allow us to extract the ratio of
isospin amplitudes A(Delta I=3/2)/A(\Delta
I=1/2)=0.420\pm0.014(stat)\pm0.016(syst) and the strong phase shift of
delta_I=(86.4+-2.8+-3.3) degrees, which is quite large and now more precisely
determined.


title:
Test experiment to search for a neutron EDM by the Laue diffraction
  method

abstract:
  A prototype experiment to measure the neutron electric dipole moment (nEDM)
by spin-rotation in a non-centrosymmetric crystal in Laue geometry was carried
out in order to investigate the statistical sensitivity and systematic effects
of the method. The statistical sensitivity to the nEDM was about $6\cdot
10^{-24}$ e$\cdot $cm per day and can be improved by one order of magnitude for
the full scale setup. Systematics was limited by the homogeneity of the
magnetic field in the crystal region and by a new kind of spin rotation effect.
We attribute this effect to a difference of the two Bloch waves amplitudes in
the crystal, which is caused by the presence of a small crystal deformation due
to a temperature gradient. In a revised scheme of the experiment, this effect
could be exploited for a purposeful manipulation of the Bloch waves.


title:
Search for anomalous semileptonic decay of heavy flavor hadrons produced
  in association with a W boson at CDF II

abstract:
  We present a search for anomalous semileptonic decays of heavy flavor hadrons
produced in association with a $W$ boson, in proton-antiproton collisions at
sqrt{s}=1.96 TeV. We use 162 pb-1 of data collected with the CDF II detector at
the Fermilab Tevatron Collider. We select events with one W boson and at least
one jet with an identified secondary vertex. In the jets with a secondary
vertex we look for a semileptonic decay to a muon. We compare the number of
jets with both a secondary vertex and a semileptonic decay, and the kinematic
properties of these jets, with the standard model expectation of W plus heavy
flavor production and decay. No discrepancy is seen between the observation and
the expectation, and we set limits on the production cross section of a B-like
hadron with an anomalously high semileptonic branching ratio.


title:
Evidence for Large Direct CP Violation in B+-=>rho(770)0K+- from
  Analysis of the Three-Body Charmless B+-=>K+-pi+-pi-+ Decay

abstract:
  We report results on a Dalitz analysis of three-body charmless
B+-=>K+-pi+-pi-+ decay including searches for direct CP violation. We report
the first observation of the decay B+=>f_2(1270)K+ with a statistical
significance above 6sigma. We also observe 3.9sigma evidence for large direct
CP violation in the B+-=>rho(770)0K+- channel. This is the first evidence for
CP violation in a charged meson decay. The results are obtained with a data
sample that contains 386 million BBbar pairs collected at the Y(4S) resonance
with the Belle detector at the KEKB asymmetric-energy e+e- collider.


title:
Measurements of the branching fractions and CP-asymmetries of B- -->
  D0_(CP) K- decays

abstract:
  We present a study of the decay B- --> D0_(CP) K- and its charge conjugate,
where D0_(CP) is reconstructed in CP-even, CP-odd, and non-CP flavor
eigenstates, based on a sample of 232 million Y(4S) --> B Bbar decays collected
with the BABAR detector at the PEP-II e+e- storage ring. We measure the
partial-rate charge asymmetries A_CP+, A_CP- and the ratios R_CP+, R_CP- of the
B --> D0 K decay branching fractions as measured in CP+, CP-, and non-CP D0
decays: A_CP+ = 0.35 +/- 0.13 (stat) +/- 0.04 (syst) A_CP- = -0.06 +/- 0.13
(stat) +/- 0.04 (syst) R_CP+ = 0.90 +/- 0.12 (stat) +/- 0.04 (syst) R_CP- =
0.86 +/- 0.10 (stat) +/- 0.05 (syst)


title: Measurement of K^+ \to \pi^0 \mu^+ \nu \gamma decay using stopped kaons

abstract:
  The K^+ \to \pi^0 \mu^+ \nu \gamma ($K_{\mu 3 \gamma}$) decay has been
measured with stopped positive kaons at the KEK 12 GeV proton synchrotron. A
$K_{\mu 3 \gamma}$ sample containing 125 events was obtained. The partial
branching ratio $Br(K_{\mu 3 \gamma}, E_{\gamma}>30 {\rm MeV}, \theta_{\mu^+
\gamma}>20^{\circ})$ was found to be $[2.4 \pm 0.5(stat) \pm 0.6(syst)]\times
10^{-5}$, which is in good agreement with theoretical predictions.


title:
Measurement of mass and width of the excited charmed meson states
  $D_1^0$ and $D_2^{*0}$

abstract:
  This paper describes a measurement of the mass and of the width of two
neutral narrow resonances $D_10$ and $D_2^{0*}$, both composed of a charm quark
and an up antiquark. The difference with respect to the well-known resonance
$D0$, also neutral and with the same quark composition, is that the two quarks
have an orbital momentum 1, which increases their binding energy. Therefore the
mass is larger than that of the $D0$. Since the relative orientation of the
spin is the same, in the limit of very large charm mass, the masses of these
resonances should be the same; their small difference is predicted by theory
and therefore important to measurement to distinguish the different models.
  These states have been observed in their decay into a kaon and three pions;
two of these particles are required to originate from a displaced vertex with
respect to the primary interaction vertex, to account for the longer lifetime
of the charmed mesons. The resonances parameters have been extracted using a
fitting procedure accounting for the expected resonance shape, including
effects from detector resolution and background, providing a new best single
measurement of the $D_10$ and $D_2^{0*}$ masses and a competitive measurement
of their widths.


title: Top Quark Mass Measurement from Dilepton Events at CDF II

abstract:
  We report a measurement of the top quark mass using events collected by the
CDF II Detector from ppbar collisions at \sqrt{s} = 1.96 TeV at the Fermilab
Tevatron. We calculate a likelihood function for the top mass in events that
are consistent with ttbar->bbar l^- \nubar b l^+ \nu decays. The likelihood is
formed as the convolution of the leading-order matrix element and detector
resolution functions. The joint likelihood is the product of likelihoods for
each of 33 events collected in 340 pb^{-1} of integrated luminosity, yielding a
top quark mass M_t = 165.2 +- 6.1 (stat.) +- 3.4(syst.) GeV/c^2. This first
application of a matrix-element technique to ttbar->bbar l^- \nubar b l^+ \nu
decays gives the most precise single measurement of M_t in dilepton events.
Combined with other CDF Run II measurements using dilepton events, we measure
M_{t} = 167.9 +- 5.2 (stat.) +- 3.7 (syst.) GeV/c^2.


title: A High Statistics Study of the Decay tau- -> pi- pi0 nu

abstract:
  We report a measurement of the branching fraction for tau- -> pi- pi0 nu and
the invariant mass spectrum of the resulting pi- pi0 system using 72.2 /fb of
data recorded by the Belle detector at the KEKB e+e- collider. The branching
fraction obtained is (25.15 +/- 0.04 +/- 0.31)%, where the first error is
statistical and the second is systematic. The unfolded pi- pi0 mass spectrum is
used to determine resonance parameters for the rho(770), rho'(1450), and
rho''(1700) mesons. We also use this spectrum to estimate the hadronic
contribution to the anomalous magnetic moment of the muon.


title:
A Search for Scalar Bottom Quarks from Gluino Decays in $\bar{p}p$
  Collisions at $\sqrt{s}=1.96$ TeV

abstract:
  We searched for scalar bottom quarks in 156 pb$^{-1}$ of {\bf $\bar{p}p$}
collisions at {\bf $\sqrt{s}=1.96$} TeV recorded by the CDF II experiment at
the Tevatron. Scalar bottom quarks can be produced from gluino decays in
R-parity conserving models of supersymmetry when the mass of the gluino exceeds
that of the scalar bottom quark. Then, a scalar bottom quark can decay into a
bottom quark and a neutralino. To search for this scenario, we investigated
events with large missing transverse energy and at least three jets, two or
more of which were identified as containing a secondary vertex from the
hadronization of $b$ quarks. We found four candidate events, where $2.6\pm 0.7$
are expected from standard model processes, and placed 95% confidence level
lower limits on gluino and scalar bottom quark masses of up to 280 and
$240\gevm$, respectively.


title: Spectroscopy of D Mesons

abstract:
  The scenario of heavy quark meson spectroscopy underwent recently a major
revolution, after the observation of BABAR and CLEO, confirmed by BELLE, of
$\DsJ$ L=1 excited states, and by further evidences by SELEX. These
experimental results have cast doubts on the incarnations of the ideas of Heavy
Quark Effective Theory in heavy quark spectroscopy. I shall review the status
of experimental data, discuss implications and sketch an outlook.


title:
Measurement of the Dipion Mass Spectrum in X(3872) -> J/Psi Pi+ Pi-
  Decays

abstract:
  We measure the dipion mass spectrum in X(3872)--> J/Psi Pi+ Pi- decays using
360 pb-1 of pbar-p collisions at 1.96 TeV collected with the CDF II detector.
The spectrum is fit with predictions for odd C-parity (3S1, 1P1, and 3DJ)
charmonia decaying to J/Psi Pi+ Pi-, as well as even C-parity states in which
the pions are from Rho0 decay. The latter case also encompasses exotic
interpretations, such as a D0-D*0Bar molecule. Only the 3S1 and J/Psi Rho
hypotheses are compatible with our data. Since 3S1 is untenable on other
grounds, decay via J/Psi Rho is favored, which implies C=+1 for the X(3872).
Models for different J/Psi-Rho angular momenta L are considered. Flexibility in
the models, especially the introduction of Rho-Omega interference, enable good
descriptions of our data for both L=0 and 1.


title:
Search for a Lorentz invariance violation in atmospheric neutrino
  oscillations using MACRO data

abstract:
  The energy spectrum of neutrino-induced upward-going muons in MACRO was
analysed in terms of special relativity principles violating effects, keeping
standard mass-induced atmospheric neutrino oscillations as the dominant source
of nu_mu <--> nu_tau transitions. The data disfavour these exotic possibilities
even at a sub-dominant level, and stringent 90% C.L. limits are placed on the
Lorentz invariance violation parameters. These limits can also be
re-interpreted as upper bounds on the parameters describing violation of the
Equivalence Principle.


title: Search for chargino and neutralino associated production at the Tevatron

abstract:
  I present a review of the searches for charginos and neutralinos using data
from proton-antiproton collision at the centre of mass energy of 1.96 TeV
collected by the CDF and the D0 experiments at the Tevatron during run II.


title: The CMS High Level Trigger

abstract:
  At the Large Hadron Collider at CERN the proton bunches cross at a rate of
40MHz. At the Compact Muon Solenoid experiment the original collision rate is
reduced by a factor of O (1000) using a Level-1 hardware trigger. A subsequent
factor of O(1000) data reduction is obtained by a software-implemented High
Level Trigger (HLT) selection that is executed on a multi-processor farm. In
this review we present in detail prototype CMS HLT physics selection
algorithms, expected trigger rates and trigger performance in terms of both
physics efficiency and timing.


title:
Measurement of the Analyzing Power $A_N$ in $pp$ Elastic Scattering in
  the CNI Region with a Polarized Atomic Hydrogen Gas Jet Target

abstract:
  A precise measurement of the analyzing power $A_N$ in proton-proton elastic
scattering in the region of 4-momentum transfer squared $0.001 < |t| < 0.032
({\rm GeV}/c)^2$ has been performed using a polarized atomic hydrogen gas jet
target and the 100 GeV/$c$ RHIC proton beam. The interference of the
electromagnetic spin-flip amplitude with a hadronic spin-nonflip amplitude is
predicted to generate a significant $A_N$ of 4--5%, peaking at $-t \simeq 0.003
({\rm GeV}/c)^2$. This kinematic region is known as the Coulomb Nuclear
Interference region. A possible hadronic spin-flip amplitude modifies this
otherwise calculable prediction. Our data are well described by the CNI
prediction with the electromagnetic spin-flip alone and do not support the
presence of a large hadronic spin-flip amplitude.


title: Eta photoproduction off the neutron at GRAAL

abstract:
  The gamma n -> eta n quasi-free cross section reveals a resonant structure at
W ~ 1.675 GeV. This structure may be a manifestation of a baryon resonance. A
priori its properties, the possibly narrow width and the strong photocoupling
to the neutron, look surprising. This structure may also signal the existence
of a narrow state.


title:
Measurement of $\sigma(\Lambda_b)/\sigma(B^0) \times
  BR(\Lambda_b\to\Lambda_c\pi^-) / BR(B^0\to D^+\pi^-)$ in $p\bar{p}$
  Collisions at $\sqrt{s}=1.96$ TeV

abstract:
  We present the first observation of the baryon decay
$\Lambda_b\to\Lambda_c\pi^-$ followed by $\Lambda_c\to p K^-\pi^+$ in 106 pb-1
of $p\bar{p}$ collisions at $\sqrt{s} = 1.96$ TeV in the CDF experiment. In
order to reduce systematic error, the measured rate for $\Lambda_b$ decay is
normalized to the kinematically similar meson decay $B^0\to D^+\pi^-$ followed
by $D^+\to\pi^+K^-\pi^+$. We report the ratio of production cross sections
($\sigma$) times the ratio of branching fractions (BR) for the momentum region
integrated above $p_T > 6$ GeV/c and pseudorapidity range $|\eta| < 1.3$:
$\sigma(p\bar{p}\to \Lambda_b X) / \sigma (p\bar{p}\to B^0 X) \times
BR(\Lambda_b\to\Lambda_c\pi^-) / BR(B^0\to D^+\pi^-) = 0.82 \pm 0.08(stat) \pm
0.11(syst) \pm 0.22 (BR(\Lambda_c\to p K^-\pi^+))$.
