title: Searches for Supersymmetry at the Tevatron

abstract:
  The results for searches for Supersymmetry (SUSY) at the Tevatron Collider
are summarized in this paper. We focus here on searches for trileptons and the
lightest stop, as well as scenarios with R-parity violation and split
supersymmetry. No significant excesses with respect to the Standard Model were
observed and constraints are set on the SUSY parameter space.


title: Top Quark Properties from the Tevatron

abstract:
  This report describes latest measurements and studies of top quark properties
from the Tevatron in RunII with an integrated luminosity of up to 750pb-1. Due
to its large mass of about 172GeV, the top quark provides a unique environment
for tests of the Standard Model and is believed to yield sensitivity to new
physics beyond the Standard Model. With data samples of close to 1fb-1 the CDF
and D0 collaborations at the Tevatron enter a new aera of precision top quark
measurements.


title: Direct CP Violation in Charmless B Decays

abstract:
  We report the updated results of direct CP violation measurements from Belle
and BaBar for the following modes: B -> h+h-/h+-pi^0, B -> eta(') h+- and B ->
K+-pi+-pi-+, where h stands for a charged kaon or pion. The data used in these
studies are up to 386 million BBbar pairs for Belle and 232 million BBbar pairs
for BaBar. The current significant measurements include: Acp(B -> K+
pi-)=-0.108+/-0.016, Acp(B -> rho0(770) K+)=0.31+0.11-0.10, and Acp(B -> eta
K+)=-0.33+/-0.12.


title:
Search for particles decaying into a Z boson and a photon in p\bar{p}
  collisions at \sqrt{s} = 1.96 TeV

abstract:
  We present the results of the first search for a new particle X produced in
$p\bar{p}$ collisions at \sqrt{s}=1.96 TeV and subsequently decaying to
Z\gamma. The search uses 0.3 fb$^{-1}$ of data collected with the D{\O}detector
at the Fermilab Tevatron Collider. We set limits on the production cross
section times the branching fraction $\sigma(p \bar{p} \to X) \times B(X\to
Z\gamma)$ that range from 0.4 -- 3.5 pb at the 95% C.L. for $X$ with invariant
masses between 100 and 1000 GeV/$c^2$ over a wide range of $X$ decay widths.


title: Search for rare decays of the Bs Meson at the Tevatron

abstract:
  We report on searches for Flavor-Changing Neutral Current (FCNC) decays in
ppbar collisions at a center of mass energy of 1.96 TeV using up to 0.78 fb-1
of data, collected at the CDF and DO detectors respectively. The rare FCNC
decays presented here are the searches for Bs-> Mu+Mu- and Bs -> phi mu+mu-.


title: Diboson Physics at the Tevatron

abstract:
  At the Fermilab Tevatron, the CDF and D0 detectors are being used to study
diboson production in $p\bar{p}$ collisions at $\sqrt{s}=1.96$ TeV. We
summarize recent measurements of the W$\gamma$, Z$\gamma$, and WW
cross-sections and limits on WZ and ZZ production. Limits on anomalous
trilinear gauge couplings are also presented.


title:
Measurements of forward-backward asymmetry in B --> K* l+ l- and
  evidence of B- --> tau- anti-nu

abstract:
  We report the first measurement of the forward-backward asymmetry and the
ratios of Wilson coefficients in B --> K* l+ l- using 386 million BBbar pairs
that were collected on the Upsilon(4S) resonance with the Belle detector at the
KEKB asymmetric-energy e+e- collider. We also present the first evidence of the
decay B- --> tau- nu_tau-bar using 414 fb^-1 of data.


title: Hot topics from Belle experiment

abstract:
  We present the first evidence of the decay B- --> tau- nu_tau-bar using 414
fb^-1 of data collected at the Upsilon(4S) resonance with the Belle detector at
the KEKB asymmetric-energy e+e- collider. Events are tagged by fully
reconstructing one of the B mesons in hadronic modes. We detect the signal with
a significance of 4.2 standard deviations including systematics, and measure
the branching fraction to be Br(B- --> tau- nu_tau-bar) = (1.06
+0.34-0.28(stat) +0.22-0.25(syst))*10^-4. We also report results based on 1.86
fb^-1 data collected by the Belle detector at the Upsilon(5S) resonance.
Several exclusive Bs decays Bs --> Ds^{(*)+} pi- (rho-) and Bs --> J/psi
phi(eta) are studied. The Bs meson production is found to proceed predominantly
through the creation of Bs^* Bsbar^* pairs. Upper limits on Bs --> K+K-, Bs -->
phi gamma, Bs --> gamma gamma and Bs --> Ds^{(*)+} Ds^{(*)-} decays are also
reported.


title: Prospects for measuring Higgs properties at the LHC

abstract:
  In the following, the prospects for measuring the SM Higgs properties at the
LHC are reviewed, in particular its mass, width, spin, CP eigenstates as well
as its couplings to the SM fermions and gauge bosons. The possibility of
performing the difficult trilinear Higgs self-coupling measurement is also
discussed.


title: Observation of psi(3770) --> gamma chi_c0

abstract:
  From e+e- collision data acquired with the CLEO-c detector at CESR, we search
for the non-DDbar decays psi(3770) -> gamma chi_cJ, with chi_cJ reconstructed
in four exclusive decays modes containing charged pions and kaons. We report
the first observation of such decays for J=0 with a branching ratio of
(0.73+-0.07+-0.06)%. The rates for different J are consistent with the
expectations assuming psi(3770) is predominantly a 1^3D_1 state of charmonium,
but only if relativistic corrections are applied.


title: phi1/beta from B -> charmonium/charm modes

abstract:
  The asymmetric B-factories have provided valuable information on CP violation
so far. In particular, one of the angles of the Unitarity Triangle,
phi1(=beta), has been measured by several approaches. Since FPCP2004, some
measurements have been updated and improved. In this letter, the latest status
of phi1 measurements, performed at BaBar and Belle experiments usgin B ->
charm/charmonium decays, are reported.


title:
Spectroscopy of ultralight bosons by photon-boson-photon
  conversion-reconversion: experimental aspects

abstract:
  A conversion-reconversion experimental scheme is proposed where photons
stored in a Fabry-Perot cavity (FP) embracing a dipole conversion magnet
generate two beams of ultralight bosons emitted in opposite directions.
Fractions of the bosons convert in dipole magnets aligned along the two boson
beam lines and generate photons of the same energy and directions of the FP
grandparent photons. The reconversion photons are detected individually by
means of single photon detectors. Such an experiment can determine the bosons
parity by measurements with different angles between the polarization vector of
linearly polarized light injected into the FP and the direction of the magnetic
field Bc of the conversion magnets. It can establish both the bosons mass m and
the coupling constant to two photons gmgg by measurements with different
lengths Lr of the string of powered regeneration magnets of one boson beam
line, while the second boson beam line is left unchanged and used for
normalization. The optimal total length Lc of the string of conversion magnets
depends on m2 and on the energy E of the laser photons. For E=2.4eV Lc is of
the order of 3m if m=10-3eV and of the order of 300m if m=10-4eV. If the
signals observed by the PVLAS experiment are due to the existence of ultralight
bosons with m=10-3eV and gmgg=10-6GeV-1, these regeneration measurements are
feasible with existing tachnology on a site of length below 100m in relatively
short periods of data taking time.


title: W and Z (plus jets) Production and Asymmetries at 1.96 TeV

abstract:
  This paper reviews the latest results from the Tevatron on W and Z physics,
and their use as probes of QCD.


title: Interference Effects in D Meson Decays

abstract:
  I review recent results on Dalitz plot analyses of D meson decays and an
analysis that takes advantage of the quantum correlations between D meson pairs
produced in the decay of the psi(3770).


title: Search for Doubly Charmed Baryons Xi_cc^+ and Xi_cc^++ in BABAR

abstract:
  We search for the production of doubly charmed baryons in e^+e^-
annihilations at or near a center-of-mass energy of 10.58 GeV, in a data sample
with an integrated luminosity of 232 fb^-1 recorded with the BABAR detector at
the PEP-II storage ring at the Stanford Linear Accelerator Center. We search
for Xi_cc^+ baryons in the final states Lambda_c^+K^-pi^+ and Xi_c^0pi^+, and
Xi_cc^++ baryons in the final states Lambda_c^+K^-pi^+pi^+ and Xi_c^0pi^+pi^+.
We find no evidence for the production of doubly charmed baryons.


title: B Spectroscopy at Tevatron

abstract:
  Recent results on heavy flavor spectroscopy from the CDF and D0 experiments
are reported in this contribution. Using up to 1 fb-1 of accumulated luminosity
per experiment, properties of X(3872), excited B** states, and the B_c meson
are measured. Also included are measurements of production rates for ground
state b hadrons in ppbar collisions.


title:
Experimental Review of Exclusive Semileptonic B Meson Decays and
  Measurements of |Vub|

abstract:
  We review the current status of experimental measurements of the branching
fractions for exclusive semileptonic decays of B mesons to charmless hadrons
and the determination of the Standard Model CKM parameter |Vub| from these
measurements.


title: Results from Charmonium Decays

abstract:
  Recent results from BES and CLEOc experiments on charmonium decays using
J/psi, psi' and psi'' data samples collected in e+e- annihilation are reviewed,
including the measurement of the relative phase between strong and
electromagnetic decays of psi', the study of the ``rho pi puzzle'' in J/psi and
psi' decays, and the search for the non-DDbar decays of psi''. The decays of
chi_cJ produced in psi' radiative transition are also reviewed. These new
results shed light on the understanding of QCD.


title: Search for Higgs bosons decaying to WW in e+e- collisions at LEP

abstract:
  A search for Higgs bosons produced in association with a fermion pair, and
decaying to WW, is performed with the data collected by the ALEPH detector at
centre-of-mass energies ranging from 191 to 209 GeV. The data correspond to an
integrated luminosity of 453.2 pb^-1. Thirteen exclusive selections are
developed according to the different final state topologies. No statistically
significant evidence for a Higgs boson decaying into a WW pair has been found.
An upper limit is derived, as a function of the Higgs boson mass, on the
product of the e+e- -> Hff cross section and the H -> WW branching ratio. The
data on the search for H -> WW are combined with previously published ALEPH
results on the search for H -> gamma gamma, to significantly extend the limits
on the mass of a fermiophobic Higgs boson.


title: phi2/alpha

abstract:
  We report the recent phi2/alpha results from Belle with KEKB accelerator and
Babar with PEP-II accelerator. The analysis of B->pi pi, B->rho rho and B->rho
pi are included in this report. These b->u u_bar d decay modes are related to
the CKM angle phi2/alpha and the method of phi2/alpha extraction of
corresponding decay are also included. After combining all the decay modes, the
constraint of phi2/alpha is 100.2+15.0-8.8 degree.


title:
Review of experimental results on rare radiative, semileptonic and
  leptonic B decays

abstract:
  We review recent experimental progress in the domain of rare radiative,
semileptonic and leptonic B decays. The statistical precision attained for
these decays has reached a level where they start to impose meaningful
constraints on the Cabibbo-Kobayashi-Maskawa matrix, which are complementary to
those obtained from hadronic decays. While the current data indicate no
deviations from Standard Model predictions, there is still some room for new
physics in these decays.


title:
W and Z Production and Standard Model Higgs Search from the Fermilab
  Tevatron

abstract:
  This paper reviews recent measurements by the D0 and CDF collaborations in
pbarp collisions at the Fermilab Tevatron at sqrt{s} = 1.96 TeV of W and Z
boson production cross sections and asymmetries. Results from both experiments
for the search of the Higgs boson predicted by the standard model in four
different decay channels are also presented.


title:
Measurement of the Top Quark Mass with a Matrix Element Method in the
  Lepton Plus Jets Channel at CDF

abstract:
  We present a measurement of the mass of the top quark from ppbar collisions
at 1.96 TeV observed with the Collider Detector at Fermilab (CDF) at the
Fermilab Tevatron Run II. The events have the decay signature of ppbar to ttbar
in the lepton plus jets channel in which at least one jet is identified as
coming from a secondary vertex and therefore a b-hadron. The largest systematic
uncertainty, the jet energy scale (JES), is convoluted with the statistical
error using an in-situ measurement of the hadronic W boson mass. We calculate a
likelihood for each event using leading-order ttbar and W+jets cross-sections
and parameterized parton showering. The final measured top quark mass and JES
systematic is extracted from a joint likelihood of the product of individual
event likelihoods. From 118 events observed in 680 pb-1 of data, we measure a
top quark mass of 174.09 +- 2.54 (stat+JES) +- 1.35 (syst) GeV/c2.


title: New Diffraction Results from the Tevatron

abstract:
  We present new results from studies on diffractive dijet production and
exclusive production of dijet and diphoton obtained by the CDF Collaboration in
proton-antiproton collisions at the Fermilab Tevatron.


title: Spin dependent fragmentatation functions at Belle

abstract:
  Spin dependent fragmentation functions are an important tool to understand
the spin structure of the nucleon. The Collins fragmentation function for
example describes the fragmentation of a transversely polarized quark into a
hadron via the creation of additional transverse momentum relative to the
quark's momentum. The Belle experiment has measured the resulting azimuthal
asymmetries in a data sample of 29 fb-1 and found significant nonzero results.


title: Quarkonium and Charm Hadrons : New Results on Spectroscopy in BaBar

abstract:
  We report on recent results in spectroscopy from BaBar. This includes the
discovery of a new $\Lambda_c$ baryon, detailed studies of the
$D^*_{sJ}(2317)^+$, $D_{sJ}(2460)^+$, X(3872) and Y(4260) particles and the
first measurement of hadronic non-$B\bar{B}$ decays of the $\Upsilon(4S)$
meson.


title: Physics at the International Linear Collider

abstract:
  The International Linear Collider (ILC) is the next large project in
accelerator based particle physics. It is complementary to the LHC in many
aspects. Measurements from both machines together will finally shed light onto
the known deficiencies of the Standard Model of particle physics and allow to
unveil a possible underlying more fundamental theory. Here, the possibilities
of the ILC will be discussed with special emphasis on the Higgs sector and on
topics with a strong connection to cosmological questions like extra dimensions
or dark matter candidates.


title: Searches for the Standard Model Higgs at the Tevatron

abstract:
  Recent preliminary results obtained by the CDF and D0 collaborations on
searches for the Standard Model (SM) Higgs boson in p bar{p} collisions at
sqrt{s} = 1.96 TeV at the Fermilab Tevatron are discussed. The data,
corresponding to integrated luminosities between 260 - 950 pb^{-1}, show no
excess of a signal above the expected background in any of the decay channels
examined. Instead, upper limits at 95% Confidence Level (C.L.) on the cross
section are established. For the first time, a combined SM cross section limit
based on 14 orthogonal analysis channels from DO is presented.


title: Heavy Flavour Production at HERA

abstract:
  The production of charm and beauty quarks in ep collisions at HERA has been
studied by the H1 and ZEUS collaborations. Charm production is generally well
described in total rate and in shape by next to leading order (NLO)
calculations in perturbative quantum chromodynamics (QCD), although in specific
phase space corners the NLO calculations underestimate the observed cross
sections. More and more beauty production data are becoming available. For this
process, NLO QCD predictions tend to be lower than the measurements.


title: D0 Hot Topics

abstract:
  We present recent DO results based on approximately 1 fb$^{-1}$ of $p
\bar{p}$ collisions at $\sqrt{s} = 1.96$ TeV recorded at the Fermilab Tevatron.
Preliminary results on a search for the flavor changing neutral current process
$D^+\to \pi^+\mu^+\mu^-$, a measurement of the CP violation parameter in $B$
mixing, $\epsilon_B$, and a two sided limit on the $B_s$ oscillation frequency
$\Delta m_s$ are presented. The limits on $\epsilon_B$ and ${\cal B}(D^+\to
\pi^+\mu^+\mu^-)$ are the world's best limits. The two sided bound on $\Delta
m_s$ is the first direct indication by a single experiment that $\Delta m_s$ is
bounded from above.


title: Semileptonic B Decays at the B Factories

abstract:
  Recent results on inclusive and exclusive semileptonic B decays from B
Factories are presented. The status and perspectives of the determination of
the CKM matrix elements Vub and Vcb with semileptonic B decays is discussed.


title: Top Quark Mass Measurements at CDF

abstract:
  The mass of the top quark M_top is interesting both as a fundamental
parameter of the standard model and as an important input to precision
electroweak tests. The Collider Detector at Fermilab (CDF) has a robust program
of top quark mass analyses, including the most precise single measurement,
M_top = 173.4 +/- 2.8 GeV/c^2, using 680 pb^-1 of ppbar collision data. A
combination of current results from CDF gives M_top = 172.0 +/- 2.7 GeV/c^2,
surpassing the stated goal of 3 GeV/c^2 precision using 2 fb^-1 of data.
Finally, a combination with current D0 results gives a world average top quark
mass of 172.5 +/- 2.3 GeV/c^2.


title: Standard Model Electroweak Measurements at LEP

abstract:
  The current status of electroweak physics results from LEP is reviewed.
Particular emphasis is placed on the latest results on the properties of the Z
and W bosons. The updated status of the global electroweak fit to the standard
model and the resulting standard model Higgs mass limits are presented.


title: Diboson physics at the Tevatron

abstract:
  Measurements of diboson events in proton-antiproton collisions at
$\sqrt{s}=1.96$ TeV are effective probes of the electro-weak gauge structure in
the Standard Model (SM). Due to the potentially high energy scale in the
collisions, bosonic operators beyond the leading order in the Lagrangian become
important at the Tevatron and make the theoretical interpretations non trivial.
The fact that we need cut-offs in our models in order to maintain unitarity
underline the importance of direct measurements at the highest possible energy
scales. I report on two new such measurement from CDF and compare to similar D0
results taken at lower integrated luminosities.


title: The LEP Testimony: Exotic Searches and Studies

abstract:
  A selection of recent results on searches for phenomena beyond the Standard
Model is presented from the LEP Collaborations, based on the data collected up
to the highest centre-of-mass energies of 209 GeV.


title: Deeply Virtual Compton Scattering at HERA II (H1 results)

abstract:
  New results on the Deeply Virtual Compton Scattering process $\gamma^* p \to
\gamma p$ (DVCS) from H1 experiment at the $e p$ collider HERA are presented,
using data collected during the year 2004 and corresponding to an integrated
luminosity of 39.7 pb$^{-1}$. The DVCS cross section is measured as a function
of the photon virtuality, $Q^2$, the $\gamma^* p $ c.m.s. energy $W$ and
differentially in the momentum transfer squared at the proton vertex, $t$, in
the kinematic range $6.5 < Q^2 < 80 $ GeV$^2$, $30 < W < 140$ GeV and $|t| < 1$
GeV$^2$. The results are found to be in good agreement with the published H1
and ZEUS measurements and compared to NLO QCD calculations based on Generalized
Parton Distributions (GPD) and to predictions from Color Dipole Model.


title:
Search for New Physics in Lepton + Photon + X Events with L=305 pb-1 of
  ppbar Collisions at roots=1.96 TeV

abstract:
  We present results of a search for anomalous production of events containing
a charged lepton (either electron or muon) and a photon, both with high
transverse momentum, accompanied by additional signatures, X, including missing
transverse energy (MET) and additional leptons and photons. We use the same
kinematic selection criteria as in a previous CDF search, but with a
substantially larger data set, 305 pb-1, a ppbar collision energy of 1.96 TeV,
and the upgraded CDF II detector. We find 42 Lepton+Photon+MET events versus a
standard model expectation of 37.3 +- 5.4 events. The level of excess observed
in Run I, 16 events with an expectation of 7.6 +- 0.7 events (corresponding to
a 2.7 sigma effect), is not supported by the new data. In the signature of
Multi-Lepton+Photon+X we observe 31 events versus an expectation of 23.0 +- 2.7
events. In this sample we find no events with an extra photon or MET and so
find no events like the one ee+gg+MET event observed in Run I.


title: Experimental review of Inclusive Semileptonic B Decays

abstract:
  The present status of the measurement of the semileptonic B decays is
reviewed. Emphasis is given on the factors affecting experimental errors of the
Cabibbo-Kobayashi-Masawa matrix element |Vcb | and |Vub |.


title:
Measurement of the $b$ Jet Cross Section in Events with a $Z$ Boson in
  $p\bar{p}$ Collisions at $\sqrt{s}$=1.96 TeV

abstract:
  A measurement of the inclusive bottom jet cross section is presented for
events containing a $Z$ boson in $p\bar{p}$ collisions at $\sqrt{s}=1.96$ TeV
using the Collider Detector at Fermilab. $Z$ bosons are identified in their
electron and muon decay modes, and $b$ jets with $E_T>20$ GeV and $|\eta|<1.5$
are identified by reconstructing a secondary decay vertex. The measurement is
based on an integrated luminosity of about 330 ${\rm pb}^{-1}$. A cross section
times branching ratio of $\sigma (Z+b {\rm jets}) \times {\cal B}(Z \to \ell^+
\ell^-)= 0.93 \pm 0.36$ pb is found, where ${\cal B}(Z\to \ell^+ \ell^-)$ is
the branching ratio of the $Z$ boson or $\gamma^*$ into a single flavor
dilepton pair ($e$ or $\mu$) in the mass range between 66 and 116 GeV$/c^2$.
The ratio of $b$ jets to the total number of jets of any flavor in the $Z$
sample, within the same kinematic range as the $b$ jets, is $2.36 \pm 0.92%$.
Here, the uncertainties are the quadratic sum of statistical and systematic
uncertainties. Predictions made with NLO QCD agree, within experimental and
theoretical uncertainties, with these measurements.


title: Measurement of P_{mu}xi in Polarized Muon Decay

abstract:
  The quantity P_{mu}^{pi}xi, where xi is one of the muon decay parameters and
$P_{\mu}^{\pi}$ is the degree of muon polarization in pion decay, has been
measured. The value P_{mu}^{pi}xi = 1.0003 +- 0.0006 stat. +- 0.0038 syst. was
obtained. This result agrees with previous measurements but is over a factor of
two more precise. It also agrees with the Standard Model prediction for
P_{mu}^{pi}xi and thus leads to restrictions on left-right symmetric models.


title:
Search for Large Extra Dimensions in the Production of Jets and Missing
  Transverse Energy in $p\bar{p}$ Collisions at $\sqrt{s}$ = 1.96 TeV

abstract:
  We present the results of a search for new physics in the jets plus missing
transverse energy data sample collected from 368 pb^{-1} of ppbar collisions at
sqrt{s}=1.96 TeV recorded by the Collider Detector at Fermilab. We compare the
number of events observed in the data with a data-based estimate of the
Standard Model backgrounds contributing to this signature. We observe no
significant excess of events, and we interpret this null result in terms of
lower limits on the fundamental Planck scale for a large extra dimensions
scenario.


title: Experimental Highlights of the RHIC Program

abstract: Experimental highlights of the RHIC program are reviewed.


title:
Measurements of the absolute branching fractions for D->Kbar pi e+ nu_e,
  D-> K*bar e+nu_e and determination of Gamma(D+ -> K*0bar e+ nu_e)/Gamma(D+ ->
  K0bar e+nu_e)

abstract:
  Using the data of about 33 pb$^{-1}$ collected at and around 3.773 GeV with
the BES-II detector at the BEPC collider, we have studied the exclusive
semileptonic decays $D^+ \to K^-\pi^+ e^+\nu_e$, $D^0 \to \bar
K^0\pi^-e^+\nu_e$, $D^+ \to \bar K^{*0}e^+\nu_e$ and $D^0 \to K^{*-}e^+\nu_e$.
The absolute branching fractions for the decays are measured to be ${BF}(D^+
\to K^-\pi^+e^+\nu_e)=(3.50\pm0.75\pm0.27)%$, ${BF}(D^0 \to \bar
K^0\pi^-e^+\nu_e)=(2.61\pm1.04\pm0.28)%$, ${BF}(D^+ \to \bar
K^{*0}e^+\nu_e)=(5.06\pm1.21\pm0.40)%$ and ${BF}(D^0 \to
K^{*-}e^+\nu_e)=(2.87\pm 1.48\pm 0.39)%$. The ratio of the vector to
pseudoscalar semileptonic decay rates $\Gamma(D^+\to\bar
K^{*0}e^+\nu_e)/\Gamma(D^+\to\bar K^0e^+\nu_e)$ is determined to be
$0.57\pm0.17\pm0.02$.


title: Results of the NEMO3 experiment

abstract:
  The purpose of the NEMO3 experiment is to detect neutrinoless double beta
decay in order to determine the nature of neutrino and its absolute mass. We
analysed the 389 effective days of data from the $\sim 7$ kg of $^{100}$Mo and
$\sim 1$ kg of $^{82}$Se and obtained the following limits on the half-life for
the \bb process: $T_{1/2}(\beta\beta0 \nu) > 4.6 \times 10^{23}$ years (Mo) and
$T_{1/2}(\beta \beta 0 \nu) > 1.0 \times 10^{23}$ years (Se). The corresponding
limits on the neutrino effective mass are $<m_{\nu}> <$ 0.7 - 2.8 eV (Mo) and
$<m_{\nu}> >$ 1.7 - 4.9 eV (Se) at 90% Confident Level. We also performed a
detailled analysis on the double beta decay of $^{100}$Mo into the excited
states $0^+_1$, $2^+_1$ of $^{100}$Ru. The results are: $T_{1/2}(\beta \beta 2
\nu \to 0^+_1) = 5.7^{+1.3}_{-0.9}(stat)\pm 0.7 (syst) \times 10^{20}$ years,
$T_{1/2}(\beta \beta 2 \nu \to 2^+_1) > 1.1 \times 10^{21}$ years,
$T_{1/2}(\beta \beta 0 \nu \to 0^+_1) > 8.9 \times 10^{22}$ years,
$T_{1/2}(\beta \beta 0 \nu \to 2^+_1) > 1.6 \times 10^{23}$ years.


title:
Measurements of the cross sections for $e^+e^- \to {\rm hadrons}$ at
  3.650, 3.6648, 3.773 GeV and the branching fraction for $\psi(3770)\to {\rm
  non-}D\bar D$

abstract:
  Using the BES-II detector at the BEPC Collider, we measured the lowest order
cross sections and the $R$ values ($R=\sigma^0_{e^+e^- \to {\rm
hadrons}}/\sigma^0_{e^+e^- \to \mu^+\mu^-}$) for inclusive hadronic event
production at the center-of-mass energies of 3.650 GeV, 3.6648 GeV and 3.773
GeV. The results lead to $\bar R_{uds}=2.224\pm 0.019\pm 0.089$ which is the
average of these measured at 3.650 GeV and 3.6648 GeV, and $R=3.793\pm 0.037
\pm 0.190$ at $\sqrt{s}=3.773$ GeV. We determined the lowest order cross
section for $\psi(3770)$ production to be $\sigma^{\rm B}_{\psi(3770)} =
(9.575\pm 0.256 \pm 0.813)~{\rm nb}$ at 3.773 GeV, the branching fractions for
$\psi(3770)$ decays to be $BF(\psi(3770) \to D^0\bar D^0)=(48.9 \pm 1.2 \pm
3.8)%$, $BF(\psi(3770) \to D^+ D^-)=(35.0 \pm 1.1 \pm 3.3)%$ and $BF(\psi(3770)
\to D\bar{D})=(83.9 \pm 1.6 \pm 5.7)%$, which result in the total non-$D\bar D$
branching fraction of $\psi(3770)$ decay to be $BF(\psi(3770) \to {\rm
non}-D\bar D)=(16.1 \pm 1.6 \pm 5.7)%$.

Measurements of the braching fractions for psi(3770)-->
  D0D0-bar,D+D-,DD-bar$ and the resonance parameters of psi(3770) and psi(2S)

abstract:
  We report measurements of the branching fractions for $\psi(3770)\to D^0 \bar
D^0, D^+D^-, D\bar D$ and resonance parameters of $\psi(3770)$ and $\psi(2S)$.
By analyzing the line-shapes of the cross sections for inclusive hadron, $D^0
\bar D^0$ and $D^+D^-$ event production in the range from 3.660 GeV to 3.872
GeV covering both $\psi(2S)$ and $\psi(3770)$ resonances, we extract the
branching fractions for $\psi(3770)$ decay into $D^0\bar D^0 {\rm and} D^+D^-$
respectively to be $B(\psi(3770)\to D^0 \bar D^0)=(46.7 \pm 4.7 \pm 2.3)%$ and
$B(\psi(3770)\to D^+ D^-)=(36.9 \pm 3.7 \pm 2.8)%$, which give $B(\psi(3770)\to
D \bar D)=(83.6 \pm 7.3 \pm 4.2)%$ and non-$D\bar D$ branching fraction of
$\psi(3770)$ to be $B(\psi(3770)\to non-D \bar D)=(16.4 \pm 7.3 \pm 4.2)%$. We
meanwhile obtain the resonance parameters of $\psi(3770)$ and $\psi(2S)$ to be
$M_{\psi(3770)}=3772.2 \pm 0.7 \pm 0.3$ MeV, $\Gamma^{\rm
tot}_{\psi(3770)}=26.9 \pm 2.4 \pm 0.3$ MeV and $\Gamma^{ee}_{\psi(3770)}=251
\pm 26 \pm 11$ eV; $M_{\psi(2S)}=3685.5 \pm 0.0 \pm 0.3$ MeV, $\Gamma^{\rm
tot}_{\psi(2S)}=331 \pm 58 \pm 2$ keV and $\Gamma^{ee}_{\psi(2S)}=2.330 \pm
0.036 \pm 0.110$ keV; as well as the $R$ value for the light hadron production
directly through one photon annihilation to be $R_{uds}=2.262\pm 0.054\pm
0.109$ in this energy region.


title:
The Beam--Charge Azimuthal Asymmetry and Deeply Virtual Compton
  Scattering

abstract:
  The first observation of an azimuthal cross--section asymmetry with respect
to the charge of the incoming lepton beam is reported from a study of hard
exclusive electroproduction of real photons. The data have been accumulated by
the HERMES experiment at DESY, in which the HERA 27.6 GeV electron or positron
beam scattered off an unpolarized hydrogen gas target. The observed asymmetry
is attributed to the interference between the Bethe--Heitler process and the
Deeply Virtual Compton Scattering (DVCS) process. The interference term is
sensitive to DVCS amplitudes, which provide the most direct access to
Generalized Parton Distributions.


title:
Study of the $e^+e^-\to\eta\gamma$ process with SND detector at the
  VEPP-2M $e^+e^-$ collider

abstract:
  In experiment with the SND detector at VEPP-2M $e^+e^-$ collider the
$e^+e^-\to\eta\gamma$ cross section was measured in the energy range
$E$=0.60--1.38 GeV with the integrated luminosity of 27.8 pb$^{-1}$. The
measured cross section is well described by the vector meson dominance model
with contributions from the $\rho(770)$, $\omega(783)$, $\phi(1020)$,
$\rho^{\prime}(1465)$ resonances and agrees with results of previous
measurements. The decay probabilities $\BR(\phi\to\eta\gamma)$,
$\BR(\omega\to\eta\gamma)$ and $\BR(\rho\to\eta\gamma)$ were measured with the
accuracies better than or comparable to the world averages.


title: Results from the Y(5S) engineering run (BELLE)

abstract:
  We report results based on a 1.86 fb$^{-1}$ data sample collected on the
$\Upsilon$(5S) resonance by the Belle detector at the KEKB asymmetric energy
$e^+ e^-$ collider. The inclusive production of $D_s$, $D^0$ and $J/\psi$
mesons at the $\Upsilon$(5S) is studied. From the $D_s$ inclusive branching
fraction the ratio $f_s = (16.4 \pm 1.4 \pm 4.1)%$ of $B_s^{(*)}
\bar{B}_s^{(*)}$ to the total $b\bar{b}$ quark pair production at the
$\Upsilon$(5S) energy is obtained in a model dependent way. The exclusive
decays $B_s \to D_s^{(*)+} \pi^- (/\rho^-)$ and $B_s \to J/\Psi \phi (/\eta)$
are studied and a significant $B_s$ signal is observed combining these modes.
The $B_s$ meson production is found to proceed predominantly through the
creation of $B^*_s \bar{B}^*_s$ pairs. Upper limits on $B_s \to K^+ K^-$, $B_s
\to \phi \gamma$, $B_s \to \gamma \gamma$ and $B_s \to D_s^{(*)+} D_s^{(*)-}$
decays are reported.


title: Tevatron Top Results

abstract:
  I present the latest results from the CDF and D0 collaborations on top quark
production (single top and top quark pair production) at the Tevatron
proton-antiproton collider at sqrt(s) =1.96 TeV, measurements of the top quark
decay properties such as the branching ratio B(t -> Wb), the W helicity in t ->
Wb decays, and measurements of fundamental parameters such as the top quark
charge and mass.


title: B physics prospects at LHCb

abstract:
  The LHCb experiment at LHC is a single-arm spectrometer designed to pursue an
extensive study of B physics and CP violation. In this contribution the physics
which will be performed by LHCb is reviewed.


title: Flavor Physics and CP Violation at LHC

abstract:
  Flavor Physics at LHC will contribute significantly to the search for New
Physics via precise and complementary measurements of CKM angles and the study
of loop decays. Here we present the expected experimental sensitivity and
physics performance of the LHC experiments that will to B-physics.


title:
Beyond the Standard Model at Belle: B to K*l+l- and search for leptonic
  B decays

abstract:
  We report the first measurement of the forward-backward asymmetry and the
ratios of Wilson coefficients A_9/A_7 and A_10/A_7 in B to K*l+l-, obtained
using 386M BBbar pairs that were collected at the Y(4S) resonance with the
Belle detector at the KEKB asymmetric-energy e+ e- collider. We also summarise
the results obtained by Belle in searches for purely leptonic B decays, with
emphasis on their impact on models of physics beyond the Standard Model.


title: Searches for Beyond SM Higgs Boson at the Tevatron

abstract:
  In the following, we describe preliminary results of searches for non-SM
higgs bosons at the CDF and D0 experiments. Both experiments use data obtained
in pp-bar collisions at the Tevatron at sqrt(s)=1.96 TeV.


title: Lepton Flavor Violating Decays - Review & Outlook

abstract:
  Here I review the status and prospects of experimental investigations into
lepton flavor violation (LFV) in charged leptons. Rare LFV processes are
naturally expected to occur through loops of TeV scale particles predicted by
supersymmetric theories or other models beyond the Standard Model. In contrast
to physics of quark flavors that is dominated by the Cabibbo-Kobayashi-Maskawa
matrix, LFV in charged leptons is a definitive signal of new physics. Currently
active researches are rare tau decay searches at the B factories. The MEG
experiment will soon start a sensitive search for the LFV muon decay, mu to e
gamma. Prospects for searches at the LHC, a possibility of a fixed target LFV
experiment with high energy muons, and a sensitivity of leptonic kaon decays to
LFV are also briefly discussed.


title: Charm and Charmonium Spectroscopy at the e+e- B-Factories

abstract:
  Over the past few years, there has been a lot of progress in the areas of
charm and charmonium spectroscopy, in large part due to the very large data
samples being accumulated at the e+e- B-Factories. In this presentation I will
focus on results in three areas: the X/Y/Z charmonium-candidate states, the
D_sJ charmed-strange mesons, and newly-discovered charmed baryons. Note the
absence of a section on pentaquarks: all B-Factory searches for pentaquarks,
charmed or otherwise, have not yielded any observation of such states.


title:
Top Quark Mass Measurement from Dilepton Events at CDF II with the
  Matrix-Element Method

abstract:
  We describe a measurement of the top quark mass using events with two charged
leptons collected by the CDF II detector from $p\bar{p}$ collisions with $\sqrt
s = 1.96$ TeV at the Fermilab Tevatron. The likelihood in top mass is
calculated for each event by convoluting the leading order matrix element
describing $q\bar{q} \to t\bar{t} \to b\ell\nu_{\ell}\bar{b}\ell'\nu_{\ell'}$
with detector resolution functions. The presence of background events in the
data sample is modeled using similar calculations involving the matrix elements
for major background processes. In a data sample with integrated luminosity of
340 pb$^{-1}$, we observe 33 candidate events and measure $M_{top} = 165.2 \pm
6.1(\textrm{stat.}) \pm 3.4(\textrm{syst.}) \mathrm{~GeV}/c^2.$ This
measurement represents the first application of this method to events with two
charged leptons and is the most precise single measurement of the top quark
mass in this channel.


title: Searches for New Physics in ep Scattering at HERA

abstract:
  The latest results from the H1 and ZEUS collaborations are presented on
leptoquark production and rare Standard Model processes. The data were taken in
the period 1994-2005, at a centre of mass energy of up to 319 GeV. Intriguing
events containing isolated leptons and missing transverse momentum, as well as
multi-lepton events, are observed by H1 in regions of phase space where the SM
prediction is low. Interpretations of the observed excesses in terms of physics
Beyond the Standard Model are also discussed.


title: Kaons: Review and Outlook

abstract:
  This article presents a review of recent results and an outlook of kaon
physics. After enjoying a renaissance, the discipline is now becoming and
endangered species. Action will be needed to keep kaon physics at the heart of
future FPCP meetings.


title: Search for Free Decay of Negative Pions in Water and Light Materials

abstract:
  We report on a search for the free decay component of pi- stopped in water
and light materials. A non-zero value of this would be an indication of
anomalous nu_e contamination to the nu_e and nu_mu_bar production at
stopped-pion neutrino facilities. No free decay component of pi- was observed
in water, Beryllium, and Aluminum, for which upper limits were established at
8.2E-4, 3.2E-3, and 7.7E-3, respectively.


title: Radiative Penguin Decays at the B Factories

abstract:
  An overview of the measurements of b->s\gamma, b->d\gamma and b->sll penguin
transitions at the B Factories is presented.


title: Effective Charges in Practice

abstract:
  Experimental results on event shapes obtained within (or related to) the
method of Effective Charges are discussed in view of measurements of the strong
coupling, alpha_s, the beta-function and non-perturbative contributions to
event shapes. The data strongly advocate to use of the ECH scheme instead of
the conventional MSbar scheme.


title:
Search for a Neutral Higgs Boson Decaying to a W Boson Pair in ppbar
  Collisions at sqrt{s} = 1.96 TeV

abstract:
  We present the results of a search for standard model Higgs boson production
with decay to WW*, identified through the leptonic final states e+ e- nubar nu
,e mu nubar nu and mu+ mu- nubbar nu. This search uses 360 pb-1 of data
collected from p pbar collisions at sqrt{s} = 1.96 TeV by the upgraded Collider
Detector at Fermilab (CDF II). We observe no signal excess and set 95%
confidence level upper limits on the production cross section times branching
ratio for the Higgs boson to WW* or any new scalar particle with similar decay
products. These upper limits range from 5.5 to 3.2 pb for Higgs boson masses
between 120 and 200 GeV/c2.


title: Measurement of the CKM angles gamma and 2 beta+gamma at B-factories

abstract:
  On behalf of the Babar and Belle collaborations, we report on the measurement
of the angle gamma and on the sum of angles 2 beta+gamma of the Unitarity
Triangle.


title: Review of New Rare Hadronic B-decay Results

abstract:
  We present a new result from Belle and many new results from BABAR for rare
hadronic B decays. These include measurements of decays involving baryons, a
Dalitz plot analysis of the three-charged-kaon system, many new results for B
decays to eta'X and omegaX, and a limit for the decay B-> a_1 rho. Measurements
of the vector-vector decays B->rhoKstar and B->omegaKstar are helping to
understand the value of the longitudinal polarization fraction for these B->VV
decays.


title: Diffractive Deep-Inelastic Scattering with a Leading Proton at HERA

abstract:
  The cross section for the diffractive deep-inelastic scattering process $ep
\to e X p$ is measured, with the leading final state proton detected in the H1
Forward Proton Spectrometer. The data analysed cover the range \xpom <0.1 in
fractional proton longitudinal momentum loss, 0.08 < |t| < 0.5 GeV^{-2} in
squared four-momentum transfer at the proton vertex, 2 < Q^2 < 50 GeV^2 in
photon virtuality and 0.004 < \beta = x / \xpom < 1, where x is the Bjorken
scaling variable. For $\xpom \lapprox 10^{-2}$, the differential cross section
has a dependence of approximately ${\rm d} \sigma / {\rm d} t \propto e^{6 t}$,
independently of \xpom, \beta and Q^2 within uncertainties. The cross section
is also measured triple differentially in \xpom, \beta and Q^2. The \xpom
dependence is interpreted in terms of an effective pomeron trajectory with
intercept $\alpha_{\pom}(0)=1.114 \pm 0.018 ({\rm stat.}) \pm 0.012 ({\rm
syst.}) ^{+0.040}_{-0.020} ({\rm model})$ and a sub-leading exchange. The data
are in good agreement with an H1 measurement for which the event selection is
based on a large gap in the rapidity distribution of the final state hadrons,
after accounting for proton dissociation contributions in the latter. Within
uncertainties, the dependence of the cross section on x and Q^2 can thus be
factorised from the dependences on all studied variables which characterise the
proton vertex, for both the pomeron and the sub-leading exchange.


title:
Measurement and QCD Analysis of the Diffractive Deep-Inelastic
  Scattering Cross Section at HERA

abstract:
  A detailed analysis is presented of the diffractive deep-inelastic scattering
process $ep\to eXY$, where $Y$ is a proton or a low mass proton excitation
carrying a fraction $1 - \xpom > 0.95$ of the incident proton longitudinal
momentum and the squared four-momentum transfer at the proton vertex satisfies
$|t|<1 {\rm GeV^2}$. Using data taken by the H1 experiment, the cross section
is measured for photon virtualities in the range $3.5 \leq Q^2 \leq 1600 \rm
GeV^2$, triple differentially in $\xpom$, $Q^2$ and $\beta = x / \xpom$, where
$x$ is the Bjorken scaling variable. At low $\xpom$, the data are consistent
with a factorisable $\xpom$ dependence, which can be described by the exchange
of an effective pomeron trajectory with intercept $\alphapom(0)= 1.118 \pm
0.008 {\rm (exp.)} ^{+0.029}_{-0.010} {\rm (model)}$. Diffractive parton
distribution functions and their uncertainties are determined from a
next-to-leading order DGLAP QCD analysis of the $Q^2$ and $\beta$ dependences
of the cross section. The resulting gluon distribution carries an integrated
fraction of around 70% of the exchanged momentum in the $Q^2$ range studied.
Total and differential cross sections are also measured for the diffractive
charged current process $e^+ p \to \bar{\nu}_e XY$ and are found to be well
described by predictions based on the diffractive parton distributions. The
ratio of the diffractive to the inclusive neutral current $ep$ cross sections
is studied. Over most of the kinematic range, this ratio shows no significant
dependence on $Q^2$ at fixed $\xpom$ and $x$ or on $x$ at fixed $Q^2$ and
$\beta$.


title: B0s Decays and B Hadron Leptonic Decays

abstract:
  Branching fractions of B^0s decays into specific CP eigenstates are
presented, and these and other results are combined in world averages to
evaluate implications on the width difference between mass or CP eigenstates,
\Delta\Gamma_s. New results on purely leptonic decays of B hadrons from the
Tevatron and B factories are also presented.


title:
Measurement of Through-Going Particle Momentum By Means Of Multiple
  Scattering With The ICARUS T600 TPC

abstract:
  The ICARUS collaboration has demonstrated, following the operation of a 600
ton (T600) detector at shallow depth, that the technique based on liquid Argon
TPCs is now mature. The study of rare events, not contemplated in the Standard
Model, can greatly benefit from the use of this kind of detectors. In
particular, a deeper understanding of atmospheric neutrino properties will be
obtained thanks to the unprecedented quality of the data ICARUS provides.
However if we concentrate on the T600 performance, most of the $\nu_\mu$
charged current sample will be partially contained, due to the reduced
dimensions of the detector. In this article, we address the problem of how well
we can determine the kinematics of events having partially contained tracks.
The analysis of a large sample of atmospheric muons collected during the T600
test run demonstrate that, in case the recorded track is at least one meter
long, the muon momentum can be reconstructed by an algorithm that measures the
Multiple Coulomb Scattering along the particle's path. Moreover, we show that
momentum resolution can be improved by a factor two using an algorithm based on
the Kalman Filtering technique.


title: Search for direct CP-violation in K+- --> pi+-pi0pi0 decays

abstract:
  A search for direct CP-violation in K+- --> pi+-pi0pi0 decays based on 47.14
million events has been performed by the NA48/2 experiment at the CERN SPS. The
asymmetry in the Dalitz plot linear slopes A_g=(g^+ - g^-)/(g^+ + g^-) is
measured to be A_g=(1.8 +- 2.6).10^{-4}. The design of the experiment and the
method of analysis provide good control of instrumental charge asymmetries in
this measurement. The precision of the result is limited by statistics and is
almost one order of magnitude better than that of previous measurements by
other experiments.


title:
Measurement of the Pion Formfactor with KLOE and Study of the Reaction
  f0(980) to pi+pi-

abstract:
  At the Frascati phi-factory DAPHNE the pion formfactor is measured by means
of the 'radiative return', i.e. by using events in which one of the collider
electrons (positrons) has radiated an initial state radiation photon, lowering
in such a way the invariant mass M_pipi of the two-pion-system. In a recent
publication of the KLOE collaboration the initial state radiation photon had
been required to be at small polar angles with respect to the beam axis. We are
presenting results from a new and complementary analysis in which the photon is
tagged at large polar angles. Only like this the threshold region M_pipi^2<0.35
GeV^2 becomes accessible. Moreover, the final state pi+pi-gamma allows to study
the phi radiative decay into the scalar particle f_0(980) with f_0(980) \to
pi+pi-. For the first time the two-pion mass spectrum could be fitted with
different theoretical models for the description of this phi radiative decay.


title: tau physics at B-factories

abstract:
  Today the B-factories BaBar and Belle have accumulated largest samples of
tau-tau events and are competing to be called tau-factories. Among the problems
to be tested and measurements to be done by BaBar and Belle are check of CP and
CPT invariance in tau decays, measurement of strange and non-strange spectral
functions, extraction of mass of strange quark and |V_us|, searches for lepton
flavor violation processes. In this paper, the latest results in tau physics by
these two experiments and measurements to be done within next few years are
reviewed.


title:
Model Independent Measurement of Form Factors in the Decay D^+ --> K^-
  pi^+ e^+ nu_e

abstract:
  We present model independent measurements of the helicity basis form factors
in the decay D+ -> K- pi+ e+ nu_e obtained from about 2800 decays reconstructed
from a 281 pb^{-1} data sample collected at the psi(3770) center-of-mass energy
with the CLEO-c detector. We confirm the existence of a previously observed
spin-zero K- pi+ component interfering with the K*0bar amplitude. We see no
evidence for additional d- or f-wave contributions.


title: Upsilon Decays

abstract:
  Bound upsilon states and their decays provide a unique laboratory for testing
QCD, LQCD, and quarkonium potential models. I review recent results, some of
which are significant improvements in precision over previous measurements and
others are first-time observations. While most of the results presented are
from CLEO III there are also notable contributions from BaBar and Belle who
have just begun to exploit their strong capabilities for studying bound state
upsilons.


title: Rare hadronic B decays

abstract:
  Rare hadronic B-meson decays allow us to study CP violation. The class of B
decays final states containing two vector mesons provides a rich set of angular
correlation observables to study. This article reviews some of the recent
experimental results from the BaBar and Belle collaborations.


title: Review of Neutrino Oscllations Experiments

abstract:
  Several experiments have sought evidence for neutrino mass and mixing via the
phenomenon of neutrino flavor oscillations. In a three neutrino model, these
oscillations are described by three angles, two mass splittings, and one CP
violating phase. Experiments using neutrinos from the Sun, the atmosphere,
nuclear reactors, and particle accelerators have gathered considerable
information on these angles and splittings. Two of the three angles are known
to be large: $\theta_{12} \simeq 33^\circ$, $\theta_{23} \simeq 45^\circ$, and
an upper limit is known on the third, $\theta_{13}<10^\circ$. Likewise, the
mass splittings are known to fall in the range $\Delta m^2_{12} \simeq 8 \times
10^{-5}$ and $|\Delta m^2_{23}| \simeq 2.4 \times 10^{-3}$ eV$^2$. Several
questions remain: the sign of the 2--3 mass splitting, the size of the unknown
angle $\theta_{13}$, and the size of the CP violating phase are yet to be
measured. Also, a report of short-baseline $\bar{\nu}_e \to \bar{\nu}_mu$
oscillations has yet to be confirmed. These open questions are the target of an
experimental neutrino oscillation program currently underway. This report will
attempt to summarize the current state of neutrino oscillation measurements and
the future program in as succinct a manner as possible.


title: Search for a pentaquark decaying to p K_S^0

abstract:
  We present a search for a pentaquark decaying strongly to $pK_S^0$ in $\gamma
N$ collisions at a center-of-mass energy up to 25 GeV/$c^2$. Finding no
evidence for such a state in the mass range of 1470 MeV/$c^2$ to 2200
MeV/$c^2$, we set limits on the yield and on the cross section times branching
ratio relative to $\Sigma^*(1385)^\pm$ and $K^*(892)^+$.


title: Study of the psi(2S) decay to p pbar pi+ pi-

abstract:
  The branching ratios of psi(2S)-->p pbar Pi+ pi- and psi(2S)-->p pbar omega,
omega--> pi+ pi- pi0 are measured and the pi+ pi- invariant mass distribution
in the first decay is discussed by analyzing
  14 million produced psi(2S) events collected by the BESII detector at the
BEPC.


title: CLEO-c Hot Topics

abstract:
  Selected recent results and future prospects for the CLEO-c experiment at
CESR are reviewed. The topics covered include measurements of leptonic and
semileptonic charm decays made with data collected at the $\psi(3770)$
resonance and results from a scan of the center-of-mass energy range from 3970
to 4260 MeV addressing the details of open-charm production and properties of
the Y(4260) state observed last year by BaBar.


title:
Measurement of the ttbar Production Cross Section in ppbar Collisions at
  sqrt(s) = 1.96 TeV

abstract:
  We present a measurement of the top quark pair production cross section in
ppbar collisions at sqrt(s)=1.96 TeV using 318 pb^{-1} of data collected with
the Collider Detector at Fermilab. We select ttbar decays into the final states
e nu + jets and mu nu + jets, in which at least one b quark from the t-quark
decays is identified using a secondary vertex-finding algorithm. Assuming a top
quark mass of 178 GeV/c^2, we measure a cross section of 8.7 +-0.9 (stat)
+1.1-0.9 (syst) pb. We also report the first observation of ttbar with
significance greater than 5 sigma in the subsample in which both b quarks are
identified, corresponding to a cross section of 10.1 +1.6-1.4(stat)+2.0-1.3
(syst) pb.


title:
Search for a heavy resonance decaying into a Z+jet final state in p-pbar
  collisions at sqrt(s) = 1.96 TeV using the D0 detector

abstract:
  We have searched for a heavy resonance decaying into a Z+jet final state in
p-pbar collisions at a center of mass energy of 1.96 TeV at the Fermilab
Tevatron collider using the D0 detector. No indication for such a resonance was
found in a data sample corresponding to an integrated luminosity of 370/pb. We
set upper limits on the cross section times branching fraction for heavy
resonance production at the 95% C.L. as a function of the resonance mass and
width. The limits are interpreted within the framework of a specific model of
excited quark production.


title: Transverse Spin Physics at HERMES

abstract:
  HERMES has measured azimuthal single-spin asymmetries of charged pions
produced in deep-inelastic scattering of positrons on a transversely polarised
hydrogen target. The presented azimuthal moments provide access to two yet
unknown quark distribution functions, the transversity distribution function
\delta q and the Sivers function f_{1T}^{perp}.


title:
Can STAR $p+p$ data help constrain fragmentation functions for strange
  hadrons

abstract:
  STAR has measured a variety of strange particle species in $p+p$ collisions
at $\sqrt{s}$=200 GeV. These high statistics data are ideal for comparing to
existing leading- and next-to-leading order perturbative QCD (pQCD) models.
Leading-order (LO) models such as PYTHIA need to be tuned to describe
identified strange particle data from STAR. We show that tuned PYTHIA can also
describe the pt-spectra of strange resonances. More rigorous Next-to-Leading
order pQCD calculations using parameterized fragmentation functions for quarks
and gluons will also be compared to STAR data. The OPAL experiment has recently
released $e^{+}e^{-}$ data from light quark flavor tagged analyses allowing for
the first time to make precise parameterizations of light flavor separated
fragmentation function. We show that our Lambda data put a more stringent
constraint on the gluon fragmentation function than $e^{+}e^{-}$ data.
Furthermore we show that pQCD fails to describe the observed enhancement of
baryon-to-meson ratio at intermediate pt (2-6 GeV/c), which may be a first
indication of other, non-perturbative mechanisms at play in $p+p$ collisions at
that momentum.


title: Electrons and Heavy Quark at PHENIX Detector

abstract:
  Measurement of heavy quark production is one of the tools used to investigate
the matter produced in extremely hot and dense conditions in heavy ion
collisions at RHIC. The PHENIX experiment has measured mid-rapidity transverse
momentum spectra of electrons. After subtracting the photonic background
contribution, the electron spectra are mainly due to semileptonic decays of
hadrons containing heavy quarks and therefore provide a measurement of heavy
quark production and its energy loss in hot and dense matter. This paper will
present the technique used by the PHENIX experiment and recent results on heavy
quark production in p+p, d+Au and Au+Au collisions at sqrt{s_NN}=200 GeV.


title:
Study of J/psi to p pbar, Lambda Lambdabar and observation of eta_c to
  Lambda Lambdabar at Belle

abstract:
  We study the baryonic charmonium decays of B mesons, B+ to etac K+ and B+ to
J/psi K+, where the etac and J/psi subsequently decay into a p pbar or Lambda
Lambdabar pair. We measure the J/psi to p pbar, Lambda Lambdabar anisotropy
parameters, alpha_B = -0.60 +- 0.13 +-0.14 (p pbar), -0.44 +- 0.51 +- 0.31
(Lambda Lambdabar) and compare to results from e+e- to J/psi formation
experiments. We also report the first observation of etac to Lambda Lambdabar.
The measured branching fraction is B(etac to Lambda Lambdabar) = (0.87 +0.24
-0.21(stat) +0.09 -0.14(syst) +- 0.27 (PDG)) x 10^-3. This study is based on a
357 fb^-1 data sample recorded on the Upsilon(4S) resonance with the Belle
detector at the KEKB asymmetric-energy e+e- collider.


title: Probing the Standard Model via rare pion and muon decays

abstract:
  The PIBETA collaboration has used a non-magnetic pure CsI calorimeter
operating at the Paul Scherrer Institute to collect the world's largest sample
of rare pion and muon decays. We have extracted the absolute pi+ -> pi0 e+ nu
decay branching ratio with the 0.55 % total uncertainty. The pi+ -> e + nu
gamma data set was used to extract weak axial and vector form factors F_A and
F_V, yielding a significant improvement in the precision of F_A and F_V. The
mu+ -> e+ nu nu gamma distributions were well described with the two-parameter
(rho_SM,eta_bar=0) solution. These results bring major improvements in accuracy
over the current Particle Data Group listings and agree well with the

title: Diffractive and exclusive measurements at CDF

abstract:
  Experimental results from the CDF experiment at the Tevatron in $p\bar{p}$
collisions at $\sqrt{s}$=1.96 TeV are presented on the diffractive structure
function at different values of the exchanged momentum transfer squared in the
range $0<Q^2<10,000$ GeV$^2$, on the four-momentum transfer $|t|$ distribution
in the region $0<|t|<1$ GeV$^2$ for both soft and hard diffractive events up to
$Q^2\approx 4,500$ GeV$^2$, and on the first experimental evidence of exclusive
production in both dijet and diphoton events. A novel technique to align the
Roman Pot detectors is also presented.


title: Double Chooz, A Search for the Neutrino Mixing Angle theta-13

abstract:
  The Double Chooz Reactor Neutrino Experiment in France plans to quickly
measure the neutrino mixing angle theta-13, or limit it to sin^2 2-theta_13
less than 0.025. The physics reach, experimental site, detector structures,
scintillator, photodetection, electronics, calibration and simulations are
described. The possibility of using Double Chooz to explore the possible use of
a antineutrino detector for non-proliferation goals is also presented.


title:
Study of Inclusive B- and Bbar0 Decays to Flavor-Tagged D, D_s and
  Lambda_c

abstract:
  We report on a study of inclusive $B^-$ and $\bar{B}^0$ meson decays to ${D^0
X}$, ${\bar{D}^0 X}$, ${D^+ X}$, ${D^- X}$, ${D_s^+ X}$, ${D_s^- X}$,
${\Lambda_c^+ X}$, ${\bar{\Lambda}_c^- X}$, based on a sample of 231 million
$B\bar{B}$ events recorded with the BABAR detector at the $\Upsilon{(4S)}$
resonance. Events are selected by completely reconstructing one $B$ and
searching for a reconstructed charm particle in the rest of the event. From the
measured branching fractions of these decays, we infer the number of charm and
anti-charm particles per $\bar{B}$ decay, separately for charged and neutral
parents. We derive the total charm yield per $B^-$ decay, $n_c^- = 1.202 \pm
0.023\pm 0.040^{+0.035}_{-0.029} $, and per $\bar{B}^0$ decay, $n_c^0 = 1.193
\pm 0.030\pm 0.034^{+0.044}_{-0.035}$ where the first uncertainty is
statistical, the second is systematic, and the third reflects the charm
branching-fraction uncertainties. We also present the charm momentum
distributions measured in the $\bar{B}$ rest frame.


title: Measurement of the Bs-Bsbar Oscillation Frequency

abstract:
  We present the first measurement of the Bs-Bsbar oscillation frequency Delta
m_s. We use 1 fb^-1 of data from p-pbar collisions at sqrt{s}=1.96 TeV
collected with the CDF II detector at the Fermilab Tevatron. The sample
contains signals of 3,600 fully reconstructed hadronic Bs decays and 37,000
partially reconstructed semileptonic Bs decays. We measure the probability as a
function of proper decay time that the Bs decays with the same, or opposite,
flavor as the flavor at production, and we find a signal consistent with
Bs-Bsbar oscillations. The probability that random fluctuations could produce a
comparable signal is 0.2%. Under the hypothesis that the signal is due to
Bs-Bsbar oscillations, we measure Delta m_s = 17.31^{+0.33}_{-0.18} (stat.) +-
0.07 (syst.) ps^-1 and determine |Vtd/Vts| = 0.208^{+0.001}_{-0.002} (exp.)
^{+0.008}_{-0.006} (theo.).


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

abstract:
  The production of charged pions in minimum bias p+C interactions is studied
using a sample of 377000 inelastic events obtained with the NA49 detector at
the CERN SPS at 158 GeV/c beam momentum. The data cover a phase space area
ranging from 0 to 1.8 GeV/c in transverse momentum and from -0.1 to 0.5 in
Feynman x. Inclusive invariant cross sections are given on a grid of 270 bins
per charge thus offering for the first time a dense coverage of the projectile
hemisphere and of the cross-over region into the target fragmentation zone.


title:
Charged Pion Production in p+C Collisions at 158 GeV/c Beam Momentum:
  Discussion

abstract:
  The new data on pion production in p+C interactions from the NA49 experiment
at the CERN SPS are used for a detailed study of hadronization in the collision
of protons with light nuclei. The comparison to the extensive set of data from
p+p collisions obtained with the same detector allows for the separation and
extraction of the projectile and target contributions to the pion yield both in
longitudinal and in transverse momentum.


title: Masses, Lifetimes and Production Rates of Xi- and anti-Xi+ at LEP 1

abstract:
  Measurements of the Xi- and anti-Xi+ masses, mass differences, lifetimes and
lifetime differences are presented. The anti-Xi+ sample used is much larger
than those used previously for such measurements. In addition, the Xi
production rates in Z -> b anti-b and Z -> q anti-q events are compared and the
position xi* of the maximum of the xi distribution in Z -> q anti-q events is
measured.


title: Search for the decay B0 --> K0_S K0_S K0_L

abstract:
  We present the first search for the decay B0 --> K0_S K0_S K0_L using a data
sample of 232 million B Bbar pairs. We find no statistically significant
evidence for the non-resonant component of this decay. Our central value for
the branching fraction, assuming the true Dalitz distribution is uniform and
excluding the phi resonance, is B(B0 --> K0_S K0_S K0_L) = (2.4 +2.7 -2.5 +/-
0.6) x 10^{-6} where the errors are statistical and systematic, respectively.
We set a single-sided Bayesian upper limit of B(B0 --> K0_S K0_S K0_L) < 7.4 x
10^{-6} at 90% confidence level using a uniform prior probability for physical
values. Assuming the worst-case true Dalitz distribution, where the signal is
entirely in the region of lowest efficiency, the 90% confidence level upper
limit is B(B0 --> K0_S K0_S K0_L) < 16 x 10^{-6}.


title: Measurement of Neutrino Oscillation by the K2K Experiment

abstract:
  We present measurements of nu_mu disappearance in K2K, the KEK to Kamioka
long-baseline neutrino oscillation experiment. One hundred and twelve
beam-originated neutrino events are observed in the fiducial volume of
Super-Kamiokande with an expectation of 158.1^{+9.2}_{-8.6} events without
oscillation. A distortion of the energy spectrum is also seen in 58 single-ring
muon-like events with reconstructed energies. The probability that the
observations are explained by the expectation for no neutrino oscillation is
0.0015% (4.3sigma). In a two flavor oscillation scenario, the allowed Delta m^2
region at sin^2(2theta) is between 1.9 and 3.5 x 10^{-3} eV^2 at the 90% C.L.
with a best-fit value of 2.8 x 10^{-3} eV^2.


title: The Physics of DAFNE and KLOE

abstract:
  DAFNE, the Frascati phi factory, has been in operation since 1999. At the
center of the physics program is the KLOE experiment, a multipurpose detector
with optimizations for tagged and interferometry-based measurements of the
neutral kaon system. KLOE has been taking data since 2000 and has helped to
explore a wide array of topics in kaon and hadronic physics, including a
comprehensive set of measurements to determine the CKM matrix element |Vus|,
and a measurement of the e+e- --> pi+pi- cross section for the determination of
the hadronic contribution to the muon anomaly. In addition, the DEAR experiment
has measured the X-ray spectrum of kaonic hydrogen, and the FINUDA experiment
has conducted its first studies in hypernuclear spectroscopy and a search for
\bar{K}-nuclear bound states. We review the design, construction, and operation
of the DAFNE facility, with an emphasis on the physics program of the KLOE
experiment.


title: Compact storage ring to search for the muon electric dipole moment

abstract:
  We present the concept of a compact storage ring of less than 0.5 m orbit
radius to search for the electric dipole moment of the muon ($d_\mu$) by
adapting the "frozen spin" method. At existing muon facilities a statistics
limited sensitivity of $d_\mu \sim 5 \times 10^{-23} \ecm$ can be achieved
within one year of data taking. Reaching this precision would demonstrate the
viability of this novel technique to directly search for charged particle EDMs
and already test a number of Standard Model extensions. At a future, high-power
muon facility a statistical reach of $d_\mu \sim 5 \times 10^{-25} \ecm$ seems
realistic with this setup.


title: Experimental Tests of Asymptotic Freedom

abstract:
  Quantum Chromodynamics (QCD), the gauge field theory of the Strong
Interaction, has specific features, asymptotic freedom and confinement, which
determine the behaviour of quarks and gluons in particle reactions at high and
at low energy scales. QCD predicts that the strong coupling strength $\as$
decreases with increasing energy or momentum transfer, and vanishes at
asymptotically high energies. In this review, the history and the status of
experimental tests of asymptotic freedom are summarised. The world summary of
measurements of $\as$ is updated, leading to an unambiguous verification of the
running of $\as$ and of asymptotic freedom, in excellent agreement with the
predictions of QCD. Averaging a set of measurements balanced between different
particle processes and the available energy range, results in a new and
improved world average of $\amz = 0.1189 \pm 0.0010 .$


title: Searches for New Physics in Lepton Final States

abstract:
  Final states containing charged leptons could provide some of the most
distinctive signatures for observing physics beyond the Standard Model. We
present searches for new physics using 0.32-0.45 /fb of data accumulated at the
Tevatron. No significant evidence of a signal is found, and in most cases the
tightest constraints to date are set on the exotic processes investigated.


title:
Search for possible solar neutrino radiative decays during total solar
  eclipses

abstract:
  Total solar eclipses (TSEs) offer a good opportunity to look for photons
produced in possible radiative decays of solar neutrinos. In this paper we
briefly review the physics bases of such searches as well as the existing
limits on the neutrino proper lifetimes obtained by such experiments. We the
report on the observations performed in occasion of the 29 March 2006 TSE, from
Waw an Namos, Libya.


title:
Hints of New Physics in the Decay Sigma-plus -> proton + mu-plus +
  mu-minus

abstract:
  The HyperCP (E871) experiment collected several billion hyperon decays in the
1997 and 1999 Fermilab fixed-target running periods. Using the data from the
1999 run, we report on the observation of three isolated events with
reconstructed masses consistent with the hypothesis Sigma-plus -> proton +
mu-plus + mu-minus. This is the rarest baryon decay ever observed. The dimuon
mass distribution is unexpectedly narrow, suggesting the decay may proceed via
an intermediate state of mass 214.3 +/- 0.5 MeV/c^2. This state is consistent
with a short-lived pseudoscalar sgoldstino with parity-conserving interactions
decaying into two unlike-sign muons.


title: Measurement of the Spin of the Omega^- Hyperon at BABAR

abstract:
  A measurement of the spin of the Omega^- hyperon produced through the
exclusive process Xi_c^0 --> Omega^- K^+ is presented using a total integrated
luminosity of 116 fb^-1 recorded with the BABAR detector at the e^+ e^-
asymmetric-energy B-Factory at SLAC. Under the assumption that the Xi_c^0 has
spin 1/2, the angular distribution of the Lambda from Omega^- --> Lambda K^-
decay is inconsistent with all half-integer Omega^- spin values other than 3/2.
Lower statistics data for the process Omega_c^0 --> Omega^- pi^+ from a 230
fb^-1 sample are also found to be consistent with Omega^- spin 3/2. If the
Xi_c^0 spin were 3/2, an Omega^- spin of 5/2 cannot be excluded.


title: B0-B0bar mixing

abstract:
  The subject of particle-antiparticle mixing in the neutral B meson systems is
reviewed. The formalism of B0-B0bar mixing is recalled and basic Standard Model
predictions are given, before experimental issues are discussed and the latest
combinations of experimental results on mixing parameters are presented,
including those on mixing-induced CP violation, mass differences, and
decay-width differences. Finally, time-integrated mixing results are used to
improve our knowledge on the fractions of the various b-hadron species produced
in Z decays and at high-energy colliders.


title: Heavy quark production at HERA and its relevance for the LHC

abstract:
  The import of HERA data on heavy quark production for LHC experiments is
discussed. Knowlegde of all aspects of the beauty and charm production process,
viz. the parton density functions of colliding hadrons, the hard scatter, and
the fragmentation of the quarks into hadrons, can aid LHC experimentation. This
short write-up concentrates on possible influences HERA data can have and on
the current status (and history) of beauty production from both HERA and
Tevatron experiments. In general, next-to-leading order QCD gives a reasonable
description of beauty production although some regions of phase space such as
low p_T show indications of differences.


title:
Measurement of the N to Delta(1232) Transition at High Momentum Transfer
  by pi0 Electroproduction

abstract:
  We report a new measurement of the exclusive electroproduction reaction
gamma* p -> pi0 p to explore the evolution from soft non-perturbative physics
to hard processes via the Q2 dependence of the magnetic (M1+), electric (E1+)
and scalar (S1+) multipoles in the N to Delta transition. 9000 differential
cross section data points cover W from threshold to 1.4 eV/c2, 4pi
center-of-mass solid angle, and Q2 from 3 to 6 GeV2/c2, the highest yet
achieved. It is found that the magnetic form factor G*M decreases with Q2 more
steeply than the proton magnetic form factor, the ratio E1+/M1+ is small and
negative, indicating strong helicity non-conservation, and the ratio S1+/M1+ is
negative, while its magnitude increases with Q2.


title:
Search for Excited and Exotic Muons in the mu+gamma Decay Channel in
  p-pbar Collisions at sqrt{s} = 1.96 TeV

abstract:
  We present a search for excited and exotic muon states mu*, conducted using
an integrated luminosity of 371 pb^{-1} of data collected in p-pbar collisions
at sqrt{s} = 1.96 TeV at the Tevatron with the CDF II detector. We search for
associated production of mu+mu* followed by the decay mu* -> mu+gamma,
resulting in the mu+mu+gamma final state. We compare the data to model
predictions as a function of the mass of the excited muon M(mu*), the
compositeness energy scale Lambda, and the gauge coupling factor f. No signal
above the standard model expectation is observed in the mu+gamma mass spectrum.
In the contact interaction model, we exclude 107 < M(mu*) < 853 GeV/c^2 for
Lambda = M(mu*); in the gauge-mediated model, we exclude 100 < M(mu) < 410
GeV/c^2 for f/Lambda = 0.01/GeV. These 95% confidence level exclusions extend
previous limits and are the first hadron collider results on mu* production in
the gauge-mediated model.


title: Recent Results from the KTeV Experiment

abstract:
  We present recent preliminary results from five decay channels. From the
$K_L\to\pi^+\pi^-\gamma$ channel, we extract form factors for the CP violating
M1 direct photon emission amplitude and the fraction of the total decay
amplitude that is due to direct emission. We have placed an upper limit on the
$K_L\to\pi^0\pi^0\gamma$ branching ratio, and preliminary measurements of the
$K_L\to\pi^{\pm}e^{\mp}\nu e^+e^-$ and $\pi^0\to e^+e^-$ branching ratios are
presented. Finally, we report measurements of both the branching ratio and the
form factor parameters for the decay $K_L\to e^+e^-\gamma$.


title:
Measurement of Interfering K^*+K^- and K^*-K^+ Amplitudes in the Decay
  D^0 --> K^+K^-pi^0

abstract:
  We have studied the Cabibbo-suppressed decay mode D^0 into K^+ K^- pi^0 using
a Dalitz plot technique and find the strong phase difference delta_D [defined
as delta_(K*^- K^+) - delta_(K*^+ K^-)] = 332 degrees +- 8 degrees +- 11
degrees and relative amplitude r_D [defined as a_(K*^- K^+) / a_(K*^+ K^-)] =
0.52 +- 0.05 +- 0.04. This measurement indicates significant destructive
interference between D^0 into K^+ (K^- pi^0)_K*^- and D^0 into K^- (K^+
pi^0)_K*^+ in the Dalitz plot region where these two modes overlap. This
analysis uses 9.0 fb^(-1) of data collected at s^(1/2) of approximately 10.58
GeV with the CLEO III detector.


title: Power Corrections in Electron-Positron Annihilation: Experimental Review

abstract:
  Experimental studies of power corrections with e+e- data are reviewed. An
overview of the available data for jet and event shape observables is given and
recent analyses based on the Dokshitzer-Marchesini-Webber (DMW) model of power
corrections are summarised. The studies involve both distributions of the
observables and their mean values. The agreement between perturbative QCD
combined with DMW power corrections and the data is generally good, and the few
exceptions are discussed. The use of low energy data sets highlights
deficiencies in the existing calculations for some observables. A study of the
finiteness of the physical strong coupling at low energies using hadronic
$\tau$ decays is shown.


title:
Observation of a broad 1^-- resonant structure around 1.5 GeV/$c^2$ in
  the K^+K^- mass spectrum in J/psi --> K^+K^-pi^0

abstract:
  A broad peak is observed at low K^+K^- invariant mass in J/psi --> K^+K^-pi^0
decays found in a sample of 5.8\times 10^7 J/psi events collected with the
BESII detector. A partial wave analysis shows that the J^PC of this structure
is 1^--. Its pole position is determined to be
(1576^{+49}_{-55}(stat)^{+98}_{-91}(syst)) MeV/c^2 -
i(409^{+11}_{-12}$(stat)^{+32}_{-67}(syst)) MeV/c^2. These parameters are not
compatible with any known meson resonances.


title: B Mixing and Lifetimes at the Tevatron

abstract:
  The Tevatron collider at Fermilab provides a very rich environment for the
study of b-hadrons. Both the D0 and CDF experiments have collected a sample of
about 1 fb^{-1}. We report results on three topics: b-hadron lifetimes,
polarization amplitudes and the decay width difference in Bs to Jpsi Phi, and
Bs mixing.


title:
K*0 and phi Meson Production in Proton-Nucleus Interactions at sqrt(s) =
  41.6 GeV

abstract:
  The inclusive production cross sections of the strange vector mesons K*0,
K*0bar, and phi have been measured in interactions of 920 GeV protons with C,
Ti, and W targets with the HERA-B detector at the HERA storage ring.
Differential cross sections as a function of rapidity and transverse momentum
have been measured in the central rapidity region and for transverse momenta up
to pT=3.5 GeV/c. The atomic number dependence is parametrised as sigma(pA) =
sigma(pN)*A**alpha, where sigma(pN) is the proton-nucleon cross section. Within
the phase space accessible, alpha(K*0) = 0.86+/-0.03, alpha(K*0bar) =
0.87+/-0.03, and alpha(phi) = 0.96+/-0.02. The total proton-nucleon cross
sections, determined by extrapolating the differential measurements to full
phase space, are sigma(pN->K*0) = 5.06+/-0.54 mb, sigma(pN->K*0bar) =
4.02+/-0.45 mb, and sigma(pN->phi) = 1.17+/-0.11 mb. The Cronin effect is
observed for the first time for vector mesons containing strange quarks;
compared to the measurements of Cronin et al. for K+- mesons, the measured
values of alpha for phi mesons coincide with those of K- mesons for all
transverse momenta, while the enhancement for K*0 / K*0bar mesons is smaller.


title: Search for the decay of a B0 or B0bar meson to K*0bar K0 or K*0 K0bar

abstract:
  We present a search for the decay of a B0 or B0bar meson to a K*0bar K0 or
K*0 K0bar final state, using a sample of approximately 232 million BBbar events
collected with the BABAR detector at the PEP-II asymmetric energy e+e- collider
at SLAC. The measured branching fraction is B(B0 --> K*0bar K0) + B(B0 --> K*0
K0bar) = (0.2+0.9-0.8+0.1-0.3)x 10-6. We obtain the following upper limit for
the branching fraction at 90% confidence level: B(B0 --> K*0bar K0) + B(B0 -->
K*0 K0bar) <1.9 x 10-6. We use our result to constrain the Standard Model
prediction for the deviation of the CP asymmetry in B0 --> phi K0 from
sin(2beta).


title:
Observation of New States Decaying into $\Lambda_c^+ K^-\pi^+$ and
  $\Lambda_c^+ K^0_S\pi^-$

abstract:
  We report the first observation of two charmed strange baryons that decay
into $\Lambda_c^+ K^-\pi^+$. The broader of the two states is measured to have
a mass of $2978.5\pm 2.1\pm 2.0$ MeV/$c^2$ and a width of $43.5\pm 7.5\pm 7.0$
MeV/$c^2$. The mass and width of the narrow state are measured to be $3076.7\pm
0.9\pm 0.5$ MeV/$c^2$ and $6.2\pm 1.2\pm 0.8$ MeV/$c^2$, respectively. We also
perform a search for the isospin partner states that decay into $\Lambda_c^+
K_S^0\pi^-$ and observe a significant signal at the mass of $3082.8\pm 1.8\pm
1.5$ MeV/$c^2$. The data used for this analysis was accumulated at or near the
$\Upsilon(4S)$ resonance, using the Belle detector at the $e^+ e^-$
asymmetric-energy collider KEKB. The integrated luminosity of the data sample
used is $461.5 ~\mathrm{fb}^{-1}$.


title: New developments in measurements of CP violation

abstract:
  We present several alternative techniques used by the BaBar Collaboration in
order to measure the Unitarity Triangle angle gamma. We also present the
results of two searches designed to improve the measurements of sin(2beta)
using penguin B decay modes by reducing the hadronic corrections uncertainties.


title: Review of Power Corrections in DIS

abstract:
  An overview is given of analyses in DIS at HERA which confront the
predictions of power corrections with measured data. These include mean values
and distributions of 2-jet as well as 3-jet event shape variables and jet
rates.


title:
Observation of $e^+e^-$ Annihilations into the $\boldmath{C=+1}$
  Hadronic Final States $\rho^0\rho^0$ and $\phi\rho^0$

abstract:
  We report the first observation of $e^+e^-$ annihilations into states of
positive $C$-parity, namely $\rho^0 \rho^0$ and $\phi\rho^0$. The two states
are observed in the $\pip\pim\pip\pim$ and $K^+K^-\pip\pim$ final states,
respectively, in a data sample of 225~$fb^{-1}$ collected by the
$BaBar$~experiment at the $PEP-II$ $e^+e^-$ storage rings at energies near
$\sqrt{s} ~=$ 10.58~$GeV$. The distributions of $\cos\theta^*$, where
$\theta^*$ is the center-of-mass polar angle of the $\phi$ meson or the forward
$\rho^0$ meson, suggest production by two-virtual-photon annihilation. We
measure cross sections within the range $|\cos\theta^*| ~<~ 0.8$ of
$\sigma(\e^+e^- \to \rho^0 \rho^0) ~=~$$20.7 \pm 0.7 (\mathrm{stat})\pm
2.7(\mathrm{syst}) ~\mathrm{fb}$ and $\sigma(\e^+e^- \to \phi \rho^0)
\~=~$$5.7\pm 0.5(\mathrm{stat}) \pm 0.8(\mathrm{syst}) ~\mathrm{fb}$.


title:
Observation of a Near-threshold $D^0\bar{D}^0\pi^0$ Enhancement in $B
  \to D^0\bar{D}^0\pi^0 K$ Decay

abstract:
  We report the first observation of a near-threshold enhancement in the
$D^0\bar{D}^0\pi^0$ system from $B \to D^0\bar{D}^0\pi^0 K$ decays using a 414
$\mathrm{fb}^{-1}$ data sample collected at the $\Upsilon(4S)$ resonance. The
enhancement peaks at a mass $M=3875.4 \pm 0.7_{-2.0}^{+1.2}$ MeV/$c^2$ and the
branching fraction for events in the peak is \Br ($B \to D^0\bar{D}^0\pi^0
K$)=(1.27 $\pm$ 0.31 $_{-0.39}^{+0.22})$ $\times$ $10^{-4}$. The data were
collected with the Belle detector at the KEKB energy-asymmetric $e^+e^-$
collider.


title: Inclusive-jet and dijet cross-sections in high-Q2 DIS at HERA

abstract:
  A new ZEUS measurement of inclusive-jet and dijet cross-sections in the Breit
frame performed in deep-inelastic ep scattering data is presented. The data
correspond to an integrated luminosity of about 82 ${\rm pb^{-1}}$ and are
resctricted to the kinematic regime $Q^2 >$125${{\rm GeV^2}}$ and -0.65$<
\cos\gamma_{had} <$0.65, where $Q^2$ is the photon virtuality and
$\cos\gamma_{had}$ corresponds to the polar angle of the hadronic system. The
cross-sections are measured as functions of various kinematic and jet
observables and are compared to NLO QCD calculations which describe the data
well within all uncertainties.


title:
Experimental Study of the Reaction $e^+e^-\to K_SK_L$ in the Energy
  Range $\sqrt{s}=1.04 \div 1.38$ GeV

abstract:
  We present a measurement of the $e^+e^-\to K_SK_L$ cross section in the
energy range $\sqrt{s}=1.04 \div 1.38$ GeV. For the energy $\sqrt{s}\geq 1.2$
GeV the cross section exceeds vector meson dominance model predictions with
only $\rho(770)$, $\omega(783)$, and $\phi(1020)$ mesons taken into account.
Measured cross section agrees well with previous measurements.


title:
Production and Detection of Axion-Like Particles at the VUV-FEL: Letter
  of Intent

abstract:
  Recently, the PVLAS collaboration has reported evidence for an anomalously
large rotation of the polarization of light generated in vacuum in the presence
of a transverse magnetic field. This may be explained through the production of
a new light spin-zero particle coupled to two photons. In this Letter of
Intent, we propose to test this hypothesis by setting up a photon regeneration
experiment which exploits the photon beam of the Vacuum-UltraViolet
Free-Electron Laser VUV-FEL, sent along the transverse magnetic field of a
linear arrangement of dipole magnets of size B L ~ 30 Tm. The high photon
energies available at the VUV-FEL increase substantially the expected photon
regeneration rate in the mass range implied by the PVLAS anomaly, in comparison
to the rate expected at visible lasers of similar power. We find that the
particle interpretation of the PVLAS result can be tested within a short
running period. The pseudoscalar vs. scalar nature can be determined by varying
the direction of the magnetic field with respect to the laser polarization. The
mass of the particle can be measured by running at different photon energies.
The proposed experiment offers a window of opportunity for a firm establishment
or exclusion of the particle interpretation of the PVLAS anomaly before other
experiments can compete.


title: Two SK-I Neutrino Sources?

abstract:
  A search for a neutrino flux difference between weekdays and weekend days was
undertaken for the average week of the Super-Kamiokande-I (SK-I) Experiment,
using the 5-day period version of the SK-I data taken from May 31st, 1996 to
July 15th, 2001. Arbitrarily uneven distributions of live time during the run
time periods were considered before rejecting the null hypothesis. Such live
time distributions were built into a robust method that calculated
time-weighted neutrino flux means. The purpose was to show that the calculated
results were unaffected by any distribution of live time, and thus that live
time had no role in rejecting the null hypothesis. A significant (p << 0.001)
difference was found and the most obvious neutrino flux change from weekdays to
weekend days can be summarized as follows: "Some neutrinos took the weekend
off, especially on Saturday".


title: Three-jet angular correlations and subjet distributions at ZEUS

abstract:
  Besides structure function measurements and jet physics, there is a lively
collection of more specific QCD analyses at HERA. In this contribution we
present three-jet angular correlations and subjet distributions measured in ep
collisions with the ZEUS detector. The angular correlations provide sensitivity
to the color factors of the underlying gauge group and thus facilitate tests of
basic properties of the strong interaction. The subjet distributions allow
tests of the QCD radiation pattern within a jet in the perturbative regime.


title:
Transverse target-spin asymmetry associated with DVCS on the proton and
  a resulting model-dependent constraint on the total angular momentum of
  quarks in the nucleon

abstract:
  Results are reported on the transverse target-spin asymmetry associated with
deeply virtual Compton scattering on the proton, extracted from the data
accumulated by the HERMES experiment in the years 2002-2004. By comparing the
HERMES results and theoretical predications based on a phenomenological model
of generalized parton distributions, a model-dependent constraint on the total
angular momentum carried by quarks in the nucleon is obtained.


title:
Search for the $\Theta^+$ pentaquark in the reactions $\gamma p \to \bar
  K^0K^+n$ and $\gamma p \to \bar K^0K^0p$

abstract:
  The exclusive reactions $\gamma p \to \bar K^0 K^+ n$ and $\gamma p \to \bar
K^0 K^0 p$ have been studied in the photon energy range 1.6--3.8 GeV, searching
for evidence of the exotic baryon $\Theta^+(1540)$ in the decays $\Theta^+\to
nK^+$ and $\Theta^+\to p K^0$. Data were collected with the CLAS detector at
the Thomas Jefferson National Accelerator Facility. The integrated luminosity
was about 70 pb$^{-1}$. The reactions have been isolated by detecting the $K^+$
and proton directly, the neutral kaon via its decay to $K_S \to \pi^+ \pi^-$
and the neutron or neutral kaon via the missing mass technique. The mass and
width of known hyperons such as $\Sigma^+$, $\Sigma^-$ and $\Lambda(1116)$ were
used as a check of the mass determination accuracy and experimental resolution.
Approximately 100,000 $\Lambda^*(1520)$'s and 150,000 $\phi$'s were observed in
the $\bar K^0 K^+ n$ and $\bar K^0 K^0 p$ final state respectively. No evidence
for the $\Theta^+$ pentaquark was found in the $nK^+$ or $pK_S$ invariant mass
spectra. Upper limits were set on the production cross section of the reaction
$\gamma p \to \Theta^+ \bar K^0$ as functions of center-of-mass angle, $nK^+$
and $pK_S$ masses. Combining the results of the two reactions, the 95% C.L.
upper limit on the total cross section for a resonance peaked at 1540 MeV was
found to be 0.7 nb. Within most of the available theoretical models, this
corresponds to an upper limit on the $\Theta^+$ width, $\Gamma_{\Theta^{+}}$,
ranging between 0.01 and 7 MeV.


title: Photon Cross Sections at Ecm = 2 TeV

abstract:
  Photon production rates have been studied by the D0 and CDF experiments in
Run II of the Fermilab Tevatron Collider. Measurements of the inclusive
isolated photon cross section and the di-photon cross section are presented,
based on integrated luminosities of 0.3 fb-1 and 0.2 fb-1, respectively. The
results are compared to perturbative QCD calculations in various
approximations.


title: Highlights from ZEUS

abstract:
  Highlights from the ZEUS experiment at HERA as of the DIS06 conference in
April are shown. New results focus on measurements from the HERA II running
period of inclusive DIS at high momentum transfer using polarised leptons and
on their impact in combined QCD and electroweak fits. Investigation of the
hadronic final state, both for inclusive and diffractive reactions, continues
to challenge theory. These are discussed as well as some previously unmeasured
hadronic final states.


title:
Evidence for a narrow structure at W~1.68 GeV in eta photoproduction on
  the neutron

abstract:
  New results on quasi-free $\eta$ photoproduction on the neutron and proton
bound in a deuteron target are presented. The $\gamma n \to \eta n$ quasi-free
cross section reveals a bump-like structure which is not seen in the cross
section on the proton. This structure may signal the existence of a relatively
narrow ($M\sim 1.68$ GeV, $\Gamma \leq 30$ MeV) baryon state.


title: Measurements of the CKM angle $\beta/\phi_1$ at the B Factories

abstract:
  We report measurements of time-dependent CP asymmetries related to the CKM
angle $\beta/\phi_1$, using decays of neutral B mesons to charmonium, open
charm and in $b\to s$ loop processes. A preliminary measurement of
time-dependent CP asymmetries in $B^0\to \rho^0(770) K^0_S$ decays from the
BaBar experiment is given here.


title: SUSY Discovery at the LHC: Extending Reach with Modern Analysis Methods

abstract: This paper has been withdrawn because it has not been vetted by CMS


title: Transverse Spin Studies with STAR at RHIC

abstract:
  STAR has observed sizable transverse single-spin asymmetries for inclusive
pi^0 production at forward rapidity in p+p collisions at sqrt{s}=200 GeV. These
asymmetries may arise from either the Sivers or Collins effect. Studies are
underway during the current RHIC run to elucidate the dynamics that underlie
these single-spin asymmetries. Additional measurements are underway to search
for the Sivers effect in mid-rapidity di-jet production.

Longitudinal Spin Transfer to the $\Lambda$ Hyperon in Semi-Inclusive
  Deep-Inelastic Scattering

abstract:
  The transfer of polarization from a high-energy positron to a \lam hyperon
produced in semi-inclusive deep-inelastic scattering has been measured. The
data have been obtained by the HERMES experiment at DESY using the 27.6 GeV
longitudinally polarized positron beam of the HERA collider and unpolarized gas
targets internal to the positron (electron) storage ring. The longitudinal spin
transfer coefficient is found to be $\dll = 0.11 \pm 0.10 \mathrm{(stat)} \pm
0.03 \mathrm{(syst)}$ at an average fractional energy carried by the \lam
hyperon $<z >= 0.45$. The dependence of \dll on both the fractional energy $z$
and the fractional longitudinal momentum $x_F$ is presented.


title: Measurement of Top Quark Properties at the Tevatron

abstract:
  We highlight the most recent top quark properties measurements performed at
the Tevatron collider by the CDF and D0 experiments. The data samples used for
the analyses discussed correspond to an integrated luminosity varying from 360
pb-1 to 760 pb-1.


title:
Search for Invisible Decays of $\eta$ and $\eta^\prime$ in $J/\psi \to
  \phi\eta$ and $\phi \eta^\prime$

abstract:
  Using a data sample of $58\times 10^6$ $J/\psi$ decays collected with the BES
II detector at the BEPC, searches for invisible decays of $\eta$ and
$\eta^\prime$ in $J/\psi$ to $\phi\eta$ and $\phi\eta^\prime$ are performed.
The $\phi$ signals, which are reconstructed in $K^+K^-$ final states, are used
to tag the $\eta$ and $\eta^\prime$ decays. No signals are found for the
invisible decays of either $\eta$ or $\eta^\prime$, and upper limits at the 90%
confidence level are determined to be $1.65 \times 10^{-3}$ for the ratio
$\frac{B(\eta\to \text{invisible})}{B(\eta\to\gamma\gamma)}$ and $6.69\times
10^{-2}$ for $\frac{B(\eta^\prime\to
\text{invisible})}{B(\eta^\prime\to\gamma\gamma)}$. These are the first
searches for $\eta$ and $\eta^\prime$ decays into invisible final states.


title: Open Charm Physics at CLEO-c

abstract:
  Recent CLEO-c results on open charm physics at the psi(3770) are presented.
Measurements of hadronic and semileptonic branching fractions of the D0 and D+
mesons are discussed as well as the leptonic decay D+ to mu+ nu_mu and
determination of the D meson decay constant.


title:
Observation of B^{\pm} \to \chi_{c1} \pi^{\pm} and Search for Direct CP
  Violation

abstract:
  We report the first observation of $B^{\pm} \to \chi_{c1} \pi^{\pm}$, the
Cabibbo- and color-suppressed decay in a data sample of $386\times 10^6$~$B\bar
B$ events collected at the $\Upsilon(4S)$ resonance with the Belle detector at
the KEKB asymmetric-energy $e^+e^-$ collider. We observe $55\pm10$ signal
events with a statistical significance of $6.3\sigma$ including systematic
uncertainties. The measured branching fraction and charge-asymmetry is
$\mathcal {B}(B^{\pm} \to \chi_{c1} \pi^{\pm}) = (2.2\pm 0.4\pm 0.3)\times
10^{-5}$ and $\mathcal{A}_{\pi} = 0.07 \pm 0.18\pm 0.02$, respectively. We also
determine the ratio $\mathcal {B}(B^{\pm} \to \chi_{c1} \pi^{\pm})/\mathcal
{B}(B^{\pm} \to \chi_{c1} K^{\pm}) = (4.3\pm 0.8\pm 0.3) %$.


title:
Search for scalar leptoquarks in the acoplanar jet topology in ppbar
  collisions at sqrt(s)=1.96 TeV

abstract:
  A search for leptoquarks has been performed in 310 pb-1 of data from ppbar
collisions at a center-of-mass energy of 1.96 TeV, collected by the D0 detector
at the Fermilab Tevatron Collider. The topology analyzed consists of acoplanar
jets with missing transverse energy. The data show good agreement with standard
model expectations, and a lower mass limit of 136 GeV has been set at the 95%
C.L. for a scalar leptoquark decaying exclusively into a quark and a neutrino.

A Search for Neutrinos from the Solar hep Reaction and the Diffuse
  Supernova Neutrino Background with the Sudbury Neutrino Observatory

abstract:
  A search has been made for neutrinos from the hep reaction in the Sun and
from the diffuse supernova neutrino background (DSNB) using data collected
during the first operational phase of the Sudbury Neutrino Observatory, with an
exposure of 0.65 kilotonne-years. For the hep neutrino search, two events are
observed in the effective electron energy range of 14.3 MeV <T_eff< 20 MeV
where 3.1 background events are expected. After accounting for neutrino
oscillations, an upper limit of 2.3x10^4 cm^-2s^-1 at the 90% confidence level
is inferred on the integral total flux of hep neutrinos. For DSNB neutrinos, no
events are observed in the effective electron energy range of 21 MeV <T_eff< 35
MeV and, consequently, an upper limit on the nu_e component of the DSNB flux in
the neutrino energy range of 22.9 MeV <E_nu< 36.9 MeV of 70 cm^-2s^-1 is
inferred at the 90% confidence level. This is an improvement by a factor of 6.5
on the previous best upper limit on the hep neutrino flux and by two orders of
magnitude on the previous upper limit on the $\nu_e$ component of the DSNB
flux.


title: Studies of Rare Hadronic B Decays with BaBar

abstract:
  We present a selection of recent results from studies of rare hadronic B
decays based on a sample of 232 million BBbar pairs, corresponding to an
integrated luminosity of 211/fb, which were recorded with the BaBar detector at
the PEP-II asymmetric-energy e+e- storage ring.


title: Stochastic Optimization for Collision Selection in High Energy Physics

abstract:
  The underlying structure of matter can be deeply probed via precision
measurements of the mass of the \emph{top quark}, the most massive observed
fundamental particle. Top quarks can be produced and studied only in collisions
at high energy particle accelerators. Most collisions, however, do not produce
top quarks; making precise measurements requires culling these collisions into
a sample that is rich in collisions producing top quarks (\emph{signal}) and
spare in collisions producing other particles (\emph{background}). Collision
selection is typically performed with heuristics or supervised learning
methods. However, such approaches are suboptimal because they assume that the
selector with the highest classification accuracy will yield a mass measurement
with the smallest statistical uncertainty. In practice, however, the mass
measurement is more sensitive to some backgrounds than others. Hence, this
paper presents a new approach that uses stochastic optimization techniques to
directly search for selectors that minimize statistical uncertainty in the top
quark mass measurement. Empirical results confirm that stochastically optimized
selectors have much smaller uncertainty. This new approach contributes
substantially to our knowledge of the top quark's mass, as the new selectors
are currently in use selecting real collisions.

Letter of Intent for KASKA: High Accuracy Neutrino Oscillation
  Measurements with anti-nu_es from Kashiwazaki-Kariwa Nuclear Power Station

abstract:
  One of the current most-demanded experiments in neutrino physics is to
measure the last mixing angle theta_13. KASKA is an experiment to detect new
type of reactor neutrino oscillation and to measure sin^2 2theta_13 accurately
using the world's most powerful nuclear reactor complex; Kashiwazaki-Kariwa
nuclear power station. KASKA utilizes near and far detectors of identical
structure at nearly optimized baselines and underground depths to cancel most
of the systematics and reduce backgrounds. The expected sensitivity is sin^2
2theta_13~0.015, which is 10 times better sensitivity than the current upper
limit measured by CHOOZ reactor experiment. Extension of KASKA project has
potential to accurately measure other anti-nu_e oscillation parameters. Intense
and precisely known neutrino flux measured by the KASKA-theta_13 phase can be
used to pin down sin^2 2theta_12 at a baseline ~50km and to measure Dm^2_13 for
the first time at a baseline ~5km. This Letter of Intent describes physics
motivation, detector system and expected performance of the KASKA experiment.


title: Spin dependent fragmentation function at Belle

abstract:
  The measurement of the so far unknown chiral-odd quark transverse spin
distribution in either semi-inclusive DIS (SIDIS) or inclusive measurements in
pp collisions at RHIC has an additional chiral-odd fragmentation function
appearing in the cross section. These chiral-odd fragmentation functions (FF)
can for example be the so-called Collins FF or the Interference FF. HERMES has
given a first hint that these FFs are nonzero, however in order to measure the
transversity one needs these FFs to be precisely known. We have used 29.0
fb$^{-1}$ of data collected by the Belle experiment at the KEKB $e^+e^-$
collider to measure azimuthal asymmetries for different charge combinations of
pion pairs and thus access the Collins FF.


title:
On-site underground background measurements for the KASKA
  reactor-neutrino experiment

abstract:
  On-site underground background measurements were performed for the planned
reactor-neutrino oscillation experiment KASKA at Kashiwazaki-Kariwa nuclear
power station in Niigata, Japan. A small-diameter boring hole was excavated
down to 70m underground level, and a detector unit for $\gamma$-ray and
cosmic-muon measurements was placed at various depths to take data. The data
were analyzed to obtain abundance of natural radioactive elements in the
surrounding soil and rates of cosmic muons that penetrate the overburden. The
results will be reflected in the design of the KASKA experiment.


title: New limit on the $K^0_L \to \pi^0 \nu \bar{\nu}$ decay rate

abstract:
  The first dedicated experiment for the rare kaon decay $K^0_L \to \pi^0 \nu
\bar{\nu}$ has been performed by the E391a collaboration at the KEK 12-GeV
proton synchrotron. A new upper limit of $2.1 \times 10^{-7}$ at the 90%
confidence level was set for the branching ratio of the decay $K^0_L \to \pi^0
\nu \bar{\nu}$ using about 10% of the data collected during the first period of
data taking.
