title: Open charm production at HERA

abstract:
  Inclusive charm meson production cross sections in the deep inelastic
scattering and photoproduction regimes are compared with QCD leading and
next-to-leading (NLO) calculations. The NLO predictions are significantly below
the data in some parts of the measured kinematic range. Angular distributions
of dijet events with charm show clear evidence for the existence of charm
originating from the incoming photon. The charm fragmentation function is
measured for the first time at HERA. Various fragmentation ratios and the
fragmentation fractions of the low-lying charm hadrons are determined and
compared to previous e+e- results.


title:
Phase Motion of the Scalar $\pi \pi$ Amplitudes in $D^+$, $D^+_s \to
  \pi^-\pi^+\pi^+$ Decays

abstract:
  We make a direct and model-independent measurement of the low $\pi^+\pi^-$
mass phase motion in the $D^+ \to \pi^-\pi^+\pi^+$ decay. Our preliminary
results show a strong phase variation, compatible with the isoscalar
$\sigma(500)$ meson. This result confirms our previous result where we found
evidence for the existence of this scalar particle using full Dalitz-plot
analysis. We apply the Amplitude Difference (AD) method to the same Fermilab
E791 data sample used in the preceding analysis. We also give an example of how
we extract the phase motion of the scalar amplitude, looking at the $f_0(980)$
in $D^+_s \to \pi^-\pi^+\pi^+$ decay.


title: Standard Model at LEPII

abstract:
  High statistics Standard Model processes like fermion- and photon-pair
production in e+e- collisions are studied at centre-of-mass energies up to 209
GeV. No significant deviation from the Standard Model is observed, leading to
strong constraints on models with additional heavy vector bosons, contact
interactions and low scale gravity. A largely model independent determination
of the Z mass becomes feasible with the measurement of gamma / Z interference
in e+e- to q q-bar at LEPII .


title: Search for a Higgs Boson Decaying to Weak Boson Pairs at LEP

abstract:
  A Higgs particle produced in association with a Z boson and decaying into
weak boson pairs is searched for in 336.4 1/pb of data collected by the L3
experiment at LEP at centre-of-mass energies from 200 to 209 GeV. Limits on the
branching fraction of the Higgs boson decay into two weak bosons as a function
of the Higgs mass are derived. These results are combined with the L3 search
for a Higgs boson decaying to photon pairs. A Higgs produced with a Standard
Model e+e- --> Zh cross section and decaying only into electroweak boson pairs
is excluded at 95% CL for a mass below 107 GeV.


title: |V_ub| and |V_cb| from CLEO

abstract:
  We report on studies of exclusive and inclusive semileptonic b -> ul\nu and b
-> cl\nu decays in 9.7 million B\barB events accumulated with the CLEO detector
in symmetric e^+e^- collisions produced in the Cornell Electron Storage Ring
(CESR). Various experimental techniques, including the inference of neutrino
candidates using the hermeticity of the CLEO detector and the study of spectral
moments, are used in conjunction with theoretical calculations to provide
estimates of the CKM matrix elements |V_ub| and |V_cb|.


title:
Search for lepton flavor violating decays of a heavy neutral particle in
  p-pbar collisions at root(s)=1.8 TeV

abstract:
  We report on a search for a high mass, narrow width particle that decays
directly to e+mu, e+tau, or mu+tau. We use approximately 110 pb^-1 of data
collected with the Collider Detector at Fermilab from 1992 to 1995. No evidence
of lepton flavor violating decays is found. Limits are set on the production
and decay of sneutrinos with R-parity violating interactions.


title:
Inelastic Scattering of Tritium-Source Antineutrinos on Electrons of
  Germanium Atoms

abstract:
  Processes of the inelastic magnetic and weak scattering of
tritium-beta-source antineutrinos on the bound electrons of a germanium atom
are considered. The results obtained by calculating the spectra and cross
sections are presented for the energy-transfer range between 1 eV and 18 keV.


title:
Measurement of Branching Fractions and Polarization in B -> phi K^{(*)}
  Decays

abstract:
  We present the first measurement of decay amplitudes in B -> phi K^* and
measurements of branching fractions in B -> phi K^{(*)} decays based on 78.1
fb^{-1} of data recorded at the Upsilon(4S) resonance with the Belle detector
at the KEKB e^+ e^- storage ring. The decay amplitudes for the different phi
K^{*0} helicity states are measured from the angular distributions of final
state particles in the transversity basis. The longitudinal and transverse
complex amplitudes are |A_0|^2 = 0.43 +- 0.09 +- 0.04, |A_perp|^2 = 0.41 +-
0.10 +- 0.04, arg(A_parallel) = -2.57 +- 0.39 +- 0.09, and arg(A_perp) = 0.48
+- 0.32 +- 0.06. The direct CP-violating asymmetries are found to be consistent
with zero.


title:
Multi-Electron Production at High Transverse Momenta in ep Collisions at
  HERA

abstract:
  Multi-electron production is studied at high electron transverse momentum in
positron- and electron-proton collisions using the H1 detector at HERA. The
data correspond to an integrated luminosity of 115 pb-1. Di-electron and
tri-electron event yields are measured. Cross sections are derived in a
restricted phase space region dominated by photon-photon collisions. In general
good agreement is found with the Standard Model predictions. However, for
electron pair invariant masses above 100 GeV, three di-electron events and
three tri-electron events are observed, compared to Standard Model expectations
of 0.30 \pm 0.04 and 0.23 \pm 0.04, respectively.


title: KLOE prospects and preliminary results for Kl3 decay measurements

abstract:
  The KLOE experiment has been running since April 1999 at the DAFNE e+e-
collider at a center of mass energy centered around the phi meson mass. The
luminosity integrated up to September 2002 is about 500 pb-1 . Here we present
the perspectives on the measurement of the V_{us} CKM-matrix element with the
KLOE detector, using both charged and neutral kaon semileptonic decays.


title: New Projects in Underground Physics

abstract:
  A large fraction of neutrino research is taking place in facilities
underground. In this paper, I review the underground facilities for neutrino
research. I discuss ideas for future reactor experiments being considered to
measure theta_13 and the UNO proton decay project.


title:
Observation of an Exotic $S=+1$ Baryon in Exclusive Photoproduction from
  the Deuteron

abstract:
  In an exclusive measurement of the reaction $\gamma d \to K^+ K^- p n$, a
narrow peak that can be attributed to an exotic baryon with strangeness $S=+1$
is seen in the $K^+n$ invariant mass spectrum. The peak is at $1.542\pm 0.005$
GeV/c$^2$ with a measured width of 0.021 GeV/c$^2$ FWHM, which is largely
determined by experimental mass resolution. The statistical significance of the
peak is $5.2 \pm 0.6 \sigma$. The mass and width of the observed peak are
consistent with recent reports of a narrow $S=+1$ baryon by other experimental
groups.


title: J/psi production from proton-proton collisions at sqrt(s) = 200 GeV

abstract:
  J/psi production has been measured in proton-proton collisions at sqrt(s)=
200 GeV over a wide rapidity and transverse momentum range by the PHENIX
experiment at RHIC. Distributions of the rapidity and transverse momentum,
along with measurements of the mean transverse momentum and total production
cross section are presented and compared to available theoretical calculations.
The total J/psi cross section is 3.99 +/- 0.61(stat) +/- 0.58(sys) +/-
0.40(abs) micro barns. The mean transverse momentum is 1.80 +/- 0.23(stat) +/-
0.16(sys) GeV/c.


title:
Status and Prospects for Measurements of $\phi_3$ from $B \to D X$
  Decays

abstract:
  Methods for extracting the Unitarity Triangle angle $\phi_3$ from B decays to
final states incluing a $D$ meson are reviewed. The current experimental status
and future prospects are summarized.


title: Study of B- => D**0 pi-(D**0 => D(*)+ pi-) decays

abstract:
  We report the results of a study of charged B decays to the D+- pi-+ pi-+ and
D*+- pi-+ pi-+ final states using complete D(*) reconstruction. The
contributions of two-body B => D** pi decays with narrow (j=3/2) and broad
(j=1/2) D** states have been determined and the masses and widths of four D**
states have been measured. This is the first observation of the broad D*0_0 and
D'0_1 mesons. The analysis is based on a data sample of 65 million B barB pairs
collected in the Belle experiment.


title: CKM Reach at Hadronic Colliders

abstract:
  The analysis of the CKM parameters will take a leap forward when the hadronic
B factories receive their first data. I describe the challenges faced by
B-physics at hadronic colliders and the expected reach in specific channels for
the LHCb, BTeV, ATLAS and CMS experiments.


title:
Quark fragmentation to $\pi^{\pm}$, $\pi^{0}$, $K^{\pm}$, $p$ and
  $\bar{p}$ in the nuclear environment

abstract:
  The influence of the nuclear medium on lepto-production of hadrons was
studied in the HERMES experiment at DESY in semi-inclusive deep-inelastic
scattering of 27.6 GeV positrons off deuterium, nitrogen and krypton targets.
The differential multiplicity for krypton relative to that of deuterium has
been measured for the first time for various identified hadrons ($\pi^+$,
$\pi^-$, $\pi^0$, $K^+$, $K^-$, $p$ and $\bar{p}$) as a function of the virtual
photon energy $\nu$, the fraction $z$ of this energy transferred to the hadron,
and the hadron transverse momentum squared $p_t^2$. The multiplicity ratio is
strongly reduced in the nuclear medium at low $\nu$ and high $z$, with
significant differences among the various hadrons. The distribution of the
hadron transverse momentum is broadened towards high $p_t^2$ in the nuclear
medium, in a manner resembling the Cronin effect previously observed in
collisions of heavy ions and protons with nuclei.


title: A new ring structure for muon (g-2) measurements

abstract:
  In a storage ring of discrete magnets with uniform field and edge focusing,
the field averaged over the orbit can be independent of orbit radius (particle
momentum). This ring is suitable for measuring the anomalous magnetic moment of
the muon. The field, averaged over the orbit, can be calibrated by injecting
transversely polarized protons of the same momentum and measuring the proton
(g-2) precession. A measurement at the level of 0.03 ppm may be feasible.


title: B_s Physics and Prospects at the Tevatron

abstract:
  Both experiments CDF and D0 at the Tevatron collider have now the first
samples of B_s particles where preliminary measurements are performed. The mass
and lifetime measurements are presented and the yield for the hadronic B_s
decays, the first step toward the B_s production fraction and branching ratio
measurements, is discussed. This also sets the bases for a re-evaluation of
mixing capabilities in Run II.


title:
Rates, Polarizations, and Asymmetries in Charmless Vector-Vector B Meson
  Decays

abstract:
  With a sample of approximately 89 million BBbar pairs collected with the
BABAR detector, we perform a search for B meson decays into pairs of charmless
vector mesons (phi, rho, and K*). We measure the branching fractions, determine
the degree of longitudinal polarization, and search for CP violation
asymmetries in the processes B->phiK*+, B->phiK*0, B->rho0K*+, and B->rho0rho+.
We also set an upper limit on the branching fraction for the decay B->rho0rho0.


title: Performance of CDF for B physics

abstract:
  Hadron colliders can be an abundant source of heavy flavor quarks, but pose a
challenge to isolate the physics signals from the high backgrounds. The
upgraded CDF II detector, with its precise tracking capabilities and powerful
trigger system, is well equipped for this task. The detector is described with
an emphasis on actual performance and on techniques to maximize the heavy
flavor yield. Some first heavy flavor results are summarized.


title: Evidence of psi(3770) non-DD-bar Decay to J/psi pi+pi-

abstract:
  Evidence of $\psi(3770)$ decays to a non-${D \bar D}$ final state is
observed. A total of $11.8 \pm 4.8 \pm 1.3$ $\psi(3770) \to \PPJP$ events are
obtained from a data sample of 27.7 $\rm {pb^{-1}}$ taken at center-of-mass
energies around 3.773 GeV using the BES-II detector at the BEPC. The branching
fraction is determined to be $BF(\psi(3770) \to \PPJP)=(0.34\pm 0.14 \pm
0.09)%$, corresponding to the partial width of $\Gamma(\psi(3770) \to \PPJP) =
(80 \pm 33 \pm 23)$ keV.


title:
Neutrinos and (Anti)neutrinos from Supernovae and from the Earth in the
  Borexino detector

abstract:
  The main goal of the Borexino detector, in its final phase of construction in
the Gran Sasso underground laboratory, is the direct observation and
measurement of the low energy component of neutrinos coming from the Sun. The
unique low energy sensitivity and ultra-low background bring new capabilities
to attack problems in neutrino physiscs other than solar ones. Investigation
about the study of Supernoavae neutrinos and neutrino coming from the Earth
(Geoneutrinos) are here resumed.


title: Kamland Results

abstract:
  The LMA solution of the solar neutrino problem has been explored with the
1,000 ton liquid scinatillator detector, KamLAND. It utilizes nuclear power
reactors distributing effectively 180km from the experimental site. Comparing
observed neutrino rate with the calculation of reactor operation histories, an
evidence for reactor neutrino disapearance has been obtained from 162 ton-year
exposure data. This deficit is only compatible with the LMA solution and the
other solutions in the two neutrino oscillation hypotheisis are excluded at
99.95% confidence level.


title: Belle Results on b --> s ell+ ell- and b --> gamma

abstract:
  We discuss the latest results and future prospects of the Belle experiment on
the electroweak and radiative processes b --> s ell+ ell-, b --> s gamma and b
--> d gamma. In particular, the first measurement of the inclusive rate for B
--> X(s) ell+ ell- provides a new constraint on the physics beyond the Standard
Model. The yet to be measured decay B --> rho gamma is expected to provide a
new constraint on the CKM matrix element |V(td)| in the near future.


title: Evidence for the Rare Decay B -> J/psi eta K

abstract:
  We report evidence for the $B$ meson decays, $B^\pm\to J/\psi \eta K^\pm$ and
$B^0\to J/\psi \eta K^0_S$, using {90} million $B\bar B$ events collected at
the $\ensuremath{\Upsilon{(4S)}}$ resonance with the \babar detector at the
PEP-II $e^+ e^-$ asymmetric-energy storage ring. We obtain preliminary
branching fractions in the charged and neutral channels of $(10.8\pm
2.3(stat.)\pm 2.4(syst.))\times 10^{-5}$ and $(8.4\pm 2.6(stat.)\pm
2.7(syst.))\times 10^{-5}$, respectively.


title: Prospects for measuring gamma at BaBar

abstract:
  The prospects for measuring the angle gamma with present day B factories are
examined. A number of approaches are discussed with reference to recent
preliminary measurements based on a data sample of approximately 88 million \BB
pairs collected by the BaBar detector at the PEP-II asymmetric B Factory at
SLAC.


title:
Observation of the Hadronic Transitions Chi_{b 1,2}(2P) -> omega
  Upsilon(1S)

abstract:
  The CLEO Collaboration has observed the first hadronic transition among
bottomonium (b bbar) states other than the dipion transitions among vector
states, Upsilon(nS) -> pi pi Upsilon(mS). In our study of Upsilon(3S) decays,
we find a significant signal for Upsilon(3S) -> gamma omega Upsilon(1S) that is
consistent with radiative decays Upsilon(3S) -> gamma chi_{b 1,2}(2P), followed
by chi_{b 1,2} -> omega Upsilon(1S). The branching ratios we obtain are
Br(chi_{b1} -> omega Upsilon(1S) = 1.63 (+0.35 -0.31) (+0.16 -0.15) % and
Br(chi_{b2} -> omega Upsilon(1S) = 1.10 (+0.32 -0.28) (+0.11 - 0.10)%, in which
the first error is statistical and the second is systematic.


title: Evidence for Two-Body Hadronic Decays of the Upsilon

abstract:
  We describe a search for hadronic decays of the Y(1S), Y(2S), and Y(3S)
resonances to the exclusive final states rho pi, K*(892) Kbar, rho a2(1320),
omega f2(1270), phi f2'(1525), K*(892) K2*(1430)bar, b1(1235) pi, K1(1270)
Kbar, and K1(1400) Kbar. Upper limits at 90% CL are set for all these decays
from all three resonances below 33x10**-6; in particular, B(Y(1S)--> rho pi) <
4x10**-6 is the smallest such upper limit. For two modes, a branching fraction
of zero can be ruled out with a statistical significance of more than 5sigma:
B(Y(1S) --> phi f2'(1525)) = (7 +3-2(stat) +-1(syst)) x 10**-6 and B(Y(1S) -->
K1(1400) Kbar) = (14 +4-3(stat) +-2(syst)) x 10**-6. Production of K1(1270)
Kbar in Y(1S) decay is suppressed relative to that of K1(1400) Kbar. These
results add another piece to the challenging ``rho-pi puzzle'' of the
charmonium system, placing constraints on models of how quantum chromodynamics
should be applied to heavy quarkonia. All results are preliminary.


title:
Study of Time-Dependent CP Asymmetries with Partial Reconstruction of B
  -> D*+ pi-

abstract:
  We present a preliminary measurement of the time-dependent CP asymmetries in
decays of neutral B mesons to the final states D*pi using approximately 82
million BBbar events collected by the BaBar experiment at the PEPII storage
ring. Events containing these decays are selected with a partial reconstruction
technique, in which only the high momentum pion and the low momentum pion from
the D* decay are reconstructed. The flavor of the other B meson in the event is
tagged using the information from kaon and lepton candidates. We measure the
time-dependent CP asymmetry A = -0.063 +/- 0.024 (stat.) +/- 0.017 (syst.). We
interpret these results in terms of the angles of the unitarity triangle to set
a bound on |sin(2 beta + gamma)|.


title: Masses, Lifetimes and Decays of B Hadrons at the Tevatron

abstract:
  The latest results in B physics from the CDF and D0 experiments at the
Tevatron are presented, including inclusive b lifetime measurement and
exclusive lifetime measurement of the B_s. Promising samples collected by CDF
with its Secondary Vertex Trigger are shown as well.


title: Contributions of Charm Physics to CKM Parameters

abstract:
  Determinations of CKM matrix elements are clouded by uncertainties in
nonperturbative QCD parameters that relate measurable quantities to the
underlying parton-level processes. A principal goal of the CLEO-c program is to
provide precision measurements in the c-quark sector that will stimulate
lattice QCD theorists to calculate relevant nonperturbative QCD parameters in
this sector and to validate the calculations. This interaction between theory
and experiment should build confidence in calculations of the parameters in the
b-quark sector required for precision determinations of the CKM matrix elements
Vcb, Vub, and Vtd.


title: Experimental update on the exclusive determination of Vcb

abstract:
  In this talk a review on the exclusive determination of Vcb is presented.
Updated values of this quantity obtained from B->Dlnu and B->D*lnu decays are
given. New measurements from B-factories are expected to come soon and the main
challenges to improve the accuracy on Vcb extracted from these decays are
discussed.


title: Experimental review on moment analyses

abstract:
  Moments of the photon energy spectrum in B -> Xs gamma decays, of the
hadronic mass spectrum and of the lepton energy spectrum in B -> Xc l nu decays
are sensitive to the masses of the heavy quarks as well as to the
non-perturbative parameters of the heavy quark expansion. Several measurements
have been performed both at the Upsilon(4S) resonance and at Z0 center of mass
energies. They provide constraints on the non-perturbative parameters, give a
test of the consistency of the theoretical predictions and of the underlying
assumptions and allow to reduce the uncertainties in the extraction of |Vcb|.


title: Observation of the DsJ(2317) and DsJ(2460) in B decays

abstract:
  We report on a study of the B --> D DsJ(2317) and B --> D DsJ(2460) decays
based on 123.7 x 10^6 BBar events collected with the Belle detector at KEKB.
The B --> D DsJ(2317) and B --> D DsJ(2460) decays have been observed for the
first time. We observe the DsJ(2317) decay to Ds pi0 and DsJ(2460) decay to the
Ds* pi0 and Ds gamma final states. We also set the 90% CL upper limits for the
decays DsJ(2317) --> Ds* gamma, DsJ(2460) --> Ds* gamma, DsJ(2460) --> Ds pi0
and DsJ(2460) --> Ds pi+ pi-.


title: Searching for eta to 3 gamma decay

abstract:
  Data collected by the KLOE experiment in years 2001/2002 for a total
integrated luminosity of 410 pb$^{-1}$, corresponding to 17 million of produced
$\eta$'s from the $\Phi \to \eta\gamma$ radiative decay, have been analyzed to
look for the C-violating decay $\eta\to\gamma\gamma\gamma$. The signal is
searched in events with 4 photons in the final state by using the spectrum of
the most energetic photon. The background is evaluated from the data themself,
doing a fifth degree polynomial fit outside the signal region, and
extrapolating inside it. No signal has been observed and taking into account a
selection efficiency $\epsilon = 20.3 %$ we get from a likelihood fit
Br$(\eta\to\gamma\gamma\gamma) \le 1.6\times10^{-5}$ at 95% CL. The procedure
has a systematic ambiguity at the 35 % level.


title:
Measurement of high-Q^2 charged current cross sections in e^+p deep
  inelastic scattering at HERA

abstract:
  Cross sections for e^+p charged current deep inelastic scattering at a
centre-of-mass energy of 318 GeV have been determined with an integrated
luminosity of 60.9pb^-1 collected with the ZEUS detector at HERA. The
differential cross sections dsigma/dQ^2, dsigma/dx and dsigma/dy for Q^2>200
GeV^2 are presented. In addition, d^2sigma/dxdQ^2 has been measured in the
kinematic range 280 GeV^2 < Q^2 < 17000 GeV^2 and 0.008 < x < 0.42. The
predictions of the Standard Model agree well with the measured cross sections.
The mass of the W boson propagator is determined to be M_W=78.9 +/- 2.0 (stat.)
+/- 1.8 (syst.) +2.0 -1.8 (PDF) GeV from a fit to dsigma/dQ^2. The chiral
structure of the Standard Model is also investigated in terms of the (1-y)^2
dependence of the the double-differential cross section. The structure-function
F_2^CC has been extracted by combining the measurements presented here with
previous ZEUS results from e^-p scattering, extending the measurement obtained
in a neutrino-nucleus scattering experiment to a significantly higher Q^2
region.


title: Heavy Flavour Electroweak Physics Review

abstract:
  The four LEP experiments and the SLD detector have measured the Z partial
widths for Z decays into b and c quarks and the corresponding forward-backward
asymmetries at centre-of-mass energies close to the Z boson mass.
  The results yield a very precise determination of the effective vector and
axial-vector coupling constants and of the underlying electroweak mixing angle
sin(theta[eff,lep]), probing the Standard Model prediction for the electroweak
radiative corrections.
  Of special interest is hereby a difference at the level of three standard
deviations in the mixing angle results from lepton production and those
obtained from the forward-backward asymmetry in b quark production. The b quark
asymmetry measurements, some of which are still in the process of being
finalised, are therefore discussed in detail.


title: Recent measurements of CP violation at the B factories

abstract:
  Recent measurements of time dependent CP asymmetries at the B factories have
led to substantial progress in our understanding of CP violation. In this
article, I review some of these experimental results and discuss their
implications in the Standard Model and their sensitivity to New Physics.


title:
Measurement of the First and Second Moments of the Hadronic Mass
  Distribution in Semileptonic B Decays

abstract:
  We report a preliminary measurement of the first and second moments of the
hadronic mass distributions in B --> X_c lv decays. The measurements are based
on Upsilon (4S) --> BBbar events where the hadronic decay of one of the B
mesons is fully reconstructed and a charged lepton from the decay of the other
B meson is identified. The moments are presented for threshold lepton momenta
ranging from 0.9 to 1.6 GeV. From the $<M_X^2>$ moments we determine the
non-perturbative Heavy Quark Expansion (HQE) parameters, $\bar{\Lambda}$ and
$\lambda_1$. We combine the measured moments $<M_X^2>$ with earlier BABAR
measurements of the semileptonic branching ratios and B lifetimes and perform a
simultaneous fit to the HQE for the moments obtained for different threshold
lepton momenta and the semileptonic decay width. This fit results in an
improved value for the CKM matrix element $|V_{cb}|$.


title: A Search for B+ to mu+ nu_mu

abstract:
  We have performed a search for the leptonic B decay B+ --> mu+ nu_mu with
data collected at the Upsilon(4S) resonance by the BABAR experiment at the
PEP-II storage ring. With an integrated luminosity of approximately 81.4 fb-1
(88.4 million BBbar pairs), we find no convincing evidence for a signal and set
a preliminary upper limit on the branching fraction of BR(B+ --> mu+ nu_mu) <
6.6 x 10^{-6} at the 90% confidence level.


title:
A study of the energy evolution of event shape distributions and their
  means with the DELPHI detector at LEP

abstract:
  Infrared and collinear safe event shape distributions and their mean values
are determined in e+e- collisions at centre-of-mass energies between 45 and 202
GeV. A phenomenological analysis based on power correction models including
hadron mass effects for both differential distributions and mean values is
presented. Using power corrections, alpha_s is extracted from the mean values
and shapes. In an alternative approach, renormalisation group invariance (RGI)
is used as an explicit constraint, leading to a consistent description of mean
values without the need for sizeable power corrections. The QCD beta-function
is precisely measured using this approach. From the DELPHI data on Thrust,
including data from low energy experiments, one finds beta_0 = 7.86 +/- 0.32
for the one loop coefficient of the beta-function or, assuming QCD, n_f = 4.75
+/- 0.44 for the number of active flavours. These values agree well with the
QCD expectation of beta_0=7.67 and n_f=5. A direct measurement of the full
logarithmic energy slope excludes light gluinos with a mass below 5 GeV.


title:
Study of Inclusive J/psi Production in Two-Photon Collisions at LEP II
  with the DELPHI Detector

abstract:
  Inclusive J/psi production in photon-photon collisions has been observed at
LEP II beam energies. A clear signal from the reaction gamma gamma -> J/psi+X
is seen. The number of observed N(J/psi -> mu+mu-) events is 36 +/- 7 for an
integrated luminosity of 617 pb^{-1}, yielding a cross-section of
sigma(J/psi+X) = 45 +/- 9 (stat) +/- 17 (syst) pb. Based on a study of the
event shapes of different types of gamma gamma processes in the PYTHIA program,
we conclude that (74 +/- 22)% of the observed J/psi events are due to
`resolved' photons, the dominant contribution of which is most probably due to
the gluon content of the photon.


title: ZZ production in e+e- interactions at sqrt(s) = 183 - 209 GeV

abstract:
  Measurements of on-shell ZZ production are described, using data from the
DELPHI experiment at LEP in e+e- collisions at centre-of-mass energies between
183 and 209 GeV, corresponding to an integrated luminosity of about 665
pb^{-1}. Results obtained in each of the final states q anti-q q anti-q, nu
anti-nu q anti-q, mu+ mu- q anti-q, e+ e- q anti-q, tau+ tau- q anti-q, l+ l-
l+ l-, and nu anti-nu l+ l- (with l=e,mu) are presented. The measured
production cross-sections are consistent with the Standard Model expectations.
These results update and supersede those already published at 183 and 189 GeV.


title:
Determination of $\sigma(e^+e^-\to \pi^+ \pi^-)$ from radiative
  processes at DA$\Phi$NE

abstract:
  We have measured the cross section $\sigma(e^+e^-\to\pi^+\pi^-\gamma)$ with
the KLOE detector at DA$\Phi$NE, at an energy $W=M_\phi=1.02$ GeV. From the
dependence of the cross section on $m(\pi^+\pi^-)=\sqrt{W^2-2WE_\gamma}$, where
$E_\gamma$ is the energy of the photon radiated from the initial state, we
extract $\sigma(e^+e^-\to\pi^+\pi^-)$ for the mass range
$0.35<m^2(\pi^+\pi^-)<0.95$ GeV$^2$. From our result we extract the pion form
factor and the hadronic contribution to the muon anomaly, $a_\mu$.


title: Measurements of the $D_{sJ}$ resonance properties

abstract:
  We report measurements of the properties of the $D_{sJ}^+(2317)$ and
$D_{sJ}^+(2457)$ resonances produced in continuum $e^+ e^-$ annihilation near
$\sqrt{s}=10.6 \mathrm{GeV}$. The analysis is based on an $86.9
\mathrm{fb^{-1}}$ data sample collected %at and 60 MeV below the $\Upsilon(4S)$
resonance with with the Belle detector at KEKB. We determine the masses to be
$M(D_{sJ}^+(2317)) = 2317.2 \pm 0.5(\mathrm{stat}) \pm 0.9(\mathrm{syst})
\mathrm{MeV}/c^2$ and $M(D_{sJ}^+(2457))=2456.5 \pm 1.3(\mathrm{stat}) \pm
1.3(\mathrm{syst}) \mathrm{MeV}/c^2$. We observe the radiative decay mode
$D_{sJ}^+(2457) \to D_s^+ \gamma$ and the dipion decay mode $D_{sJ}^+(2457) \to
D_s^+ \pi^+ \pi^-$, and determine their branching fractions. No corresponding
decays are observed for the $D_{sJ}(2317)$ state. These results are consistent
with the spin-parity assignments of $0^+$ for the $D_{sJ}(2317)$ and $1^+$ for
the $D_{sJ}(2457)$.


title:
New, high statistics measurement of the K+ -> pi0 e+ neutrino (K+e3)
  branching ratio

abstract:
  E865 at the Brookhaven National Laboratory AGS collected about 70,000 K+e3
events with the purpose of measuring the K+e3 branching ratio relative to the
observed K+ ->pi+pi0, K+ -> pi0 mu+ neutrino, and K+ -> pi+ pi0 pi0 decays. The
pi0 in all the decays was detected using the e+e- pair from pi0 -> e+e- gamma
decay and no photons were required. Using the Particle Data Group branching
ratios for the normalization decays we obtain BR(Ke3gamma) = (5.13 +- 0.02stat
+- 0.09sys +- 0.04norm)%, where K+e3gamma includes the effect of virtual and
real photons (inclusive measurement). This result is ~ 2.3 sigma higher than
the current Particle Data Group value. The implications of this result for the
Vus element of the CKM matrix, and the matrix's unitarity are discussed.


title:
Measurement of the branching ratio for the decay $K^\pm \to \pi^\pm
  \pi^0 \pi^0$ with the KLOE detector

abstract:
  A new measurement of the absolute branching ratio BR($K^\pm \to \pi^\pm \pi^0
\pi^0$) with the KLOE detector at the DA$\Phi$NE $e^+e^-$ collider is
presented, based on a sample of $\sim 3.3\times 10^7$ charged kaons tagged
events, produced in the reaction $e^+e^-\to\phi\to K^+K^-$.The value BR($K^\pm
\to \pi^\pm \pi^0 \pi^0$) $= (1.781\pm 0.013_{stat}\pm 0.016_{syst})%$ has been
obtained.


title:
Light quark and charm interplay in the Dalitz-plot analysis of hadronic
  decays in FOCUS

abstract:
  The potentiality of interpreting the D-meson decay-dynamics has revealed
itself to be strongly dependent on our understanding of the light-meson sector.
The statistics collected by FOCUS is already at a level that manifests
parametrization problems for scalar particles. In this paper the first
application of the K-matrix approach in the charm sector is illustrated and
preliminary results on the D+ and Ds decays to three pions are shown.


title: Four-fermion production and limits on anomalous couplings at LEP-2

abstract:
  Electroweak processes with four fermions in the final state were measured
extensively at LEP-2 in e+e- collisions with centre-of-mass energies up to 209
GeV. By combining the results obtained by Aleph, Delphi, L3 and Opal, the
predictions from the Standard Model were probed at the level of their present
accuracy. An important outcome was the possibility to measure the predicted
charged triple gauge boson self-couplings with a precision of a few percent.
Moreover studies of four-fermion processes allowed new physics to be searched
for by looking for anomalous gauge boson self-couplings. The measurements
reported are also relevant to direct searches for new particles at LEP, as
four-fermion processes contribute an important background in several cases. The
latest results from the LEP experiments - some of which are now available in
finalized form - and their combination are reviewed and discussed.


title: Non-SUSY searches at the Tevatron

abstract:
  As the integrated luminosity of the Run II Tevatron increases, the
sensitivity to new physics is approaching and in some cases surpassing that
previously attained in Run I. Presented below are a selection of new results
from searches for physics beyond the Standard Model at the CDF and D0
experiments.


title:
Partial Wave Analyses of $J/\psi\to\gamma K^+K^-$ and $\gamma
  K^0_SK^0_S$

abstract:
  Results are presented on $J/\psi $ radiative decays to $K^+K^-$ and
$K^0_SK^0_S$ based on a sample of 58M $J/\psi$ events taken with the BES II
detector. A partial wave analysis is carried out using the relativistic
covariant tensor amplitude method in the 1-2 GeV mass range. There is
conspicuous production due to the $f'_2(1525)$ and $f_0(1710)$. The latter
peaks at a mass of $1740\pm 4^{+10}_{-25}$ MeV with a width of
$166{^{+5}_{-8}}{^{+15}_{-10}}$ MeV. Spin 0 is strongly preferred over spin 2.
For the $f'_2(1525)$, the helicity amplitude ratios are determined to be $x^2 =
1.00\pm0.28^{+1.06}_{-0.36}$ and $y^2 = 0.44\pm{0.08}^{+0.10}_{-0.56}$.


title: Chasing the GZK with HiRes

abstract:
  The HiRes Collaboration has recently announced preliminary measurements of
the energy spectrum of ultra-high energy cosmic rays (UHECR), as seen in
monocular analyses from each of the two HiRes sites. This spectrum is
consistent with the existence of the GZK cutoff, as well other aspects of the
energy loss processes that cause the GZK cutoff. Based on the analytic energy
loss formalism of Berezinsky {\it et al.}, the HiRes spectra favor a
distribution of extragalactic sources that has a similar distribution to that
of luminous matter in the universe, both in its local over-density and in its
cosmological evolution.


title: Status and perspectives of sin2alpha measurements

abstract:
  In the neutral B meson system, it is possible to measure the CKM angle alpha
using the decay mode b -> u ubar d in the presence of pollution from gluonic b
-> d penguin decays. Here the recent status of the measurements of CP-violating
asymmetry parameters using time-dependent analyses in
  B -> pi+pi- and B -> rho pi decays and the perspectives of a sin2alpha
measurement are presented.


title: Observation of B+ -> psi(3770) K+

abstract:
  We report the first observation of the decay B+ -> psi(3770) K+ where
psi(3770) is reconstructed in the D0D0-bar and D+D- decay channels. The
obtained branching fraction is Br(B+ -> psi(3770)
K+)=(0.48+-0.11+-0.07)x10^{-3}. We have measured the branching fraction for the
decay B+ -> D0D0-bar K+ to be (1.17+-0.21+-0.15)x10^{-3}. We have set a 90%
confidence level upper limit of 0.90x10^{-3} for the decay B+ -> D+D-K+. We
also present the results of a search for possible decays to DD-bar and D0D0-bar
pi0 of the recently observed X(3872) particle. The analysis is based on 88
fb^{-1} of data collected at the Upsilon(4S) resonance by the Belle detector at
the KEKB asymmetric-energy e+e- collider.


title:
Measurement of the Inclusive Charmless Semileptonic Branching Ratio of B
  Mesons and Determination of |V_ub|

abstract:
  We report a measurement of the inclusive charmless semileptonic branching
fraction of B mesons in a sample of 89 million BBbar events recorded with the
BABAR detector at the Y(4S) resonance. Events are selected by fully
reconstructing the decay of one B meson and identifying a charged lepton from
the decay of the other B meson. The number of signal events is extracted from
the hadronic mass distribution and is used to determine the ratio of branching
fractions BR(B->Xulnu)/BR(B->Xlnu) = (2.06 +/-0.25(stat) +/-0.23(syst)
+/-0.36(theo)) x 10^{-2}. Using the measured branching fraction for inclusive
semileptonic B decays, we find BR(B->Xulnu) = (2.24 +/- 0.27(stat) +/-
0.26(syst) +/- 0.39(theo)) x 10^{-3} and derive the CKM matrix element |Vub| =
(4.62 +/- 0.28(stat) +/- 0.27(syst) +/- 0.48 (theo)) x 10^{-3}.


title: Charm Changing Neutral Currents and Supersymmetry

abstract:
  Flavor changing neutral currents (FCNCs) in the charm system are highly
suppressed in the standard model (SM). The theoretical strategies used to
suppress FCNCs induced by supersymmetry in the strange and beauty systems need
not apply to the charm system. The charm changing neutral current decay D^0->
mu^+ mu^- is studied phenomenologically in the framework of supersymmetric
extensions of the standard model. It is found that the decay branching ratio
can be enhanced to about 10^{-10}, by having heavy non-degenerate
supersymmetric strange or bottom quarks, with negligible effect on the strange
and beauty FCNC processes. The D^0 mixing rate also receives enhancement in
these models, but is generally below the present experimental limit. The
prospects for measuring D^0-> mu^+ mu^- to 10^{-10} levels, a definitive
signature of new physics beyond the SM, in the near future are discussed.


title:
Flavor decomposition of the sea quark helicity distributions in the
  nucleon from semi-inclusive deep-inelastic scattering

abstract:
  Double-spin asymmetries of semi-inclusive cross sections for the production
of identified pions and kaons have been measured in deep-inelastic scattering
of polarized positrons on a polarized deuterium target. Five helicity
distributions including those for three sea quark flavors were extracted from
these data together with re-analyzed previous data for identified pions from a
hydrogen target. These distributions are consistent with zero for all three sea
flavors. A recently predicted flavor asymmetry in the polarization of the light
quark sea appears to be disfavored by the data.


title: Towards Robust Averaging of Exclusive B ->X_u l nu Measurements

abstract:
  I present a brief overview of the measurements of exclusive B -> X_u l nu
transitions, with a focus on issues facing robust averaging of branching
fractions and |Vub| from current and anticipated measurements.


title:
Measurement of the Cross-Section for the Process Gamma-Gamma to
  Proton-Antiproton at sqrt(s_ee) = 183 - 189 GeV with the OPAL Detector at LEP

abstract:
  The exclusive production of proton-antiproton pairs in the collisions of two
quasi-real photons has been studied using data taken at sqrt(s_ee) = 183 GeV
and 189 GeV with the OPAL detector at LEP. Results are presented for
proton-antiproton invariant masses, W, in the range 2.15 < W < 3.95 GeV. The
cross-section measurements are compared with previous data and with recent
analytic calculations based on the quark-diquark model.


title: sin(2beta): Status and Prospects

abstract:
  An overview of the observation of CP violation in the neutral B system, and
the measurements of the CP violating asymmetry sin(2beta) with B to charmonium
K^0_{S,L} events, performed by the BaBar and Belle experiments at the SLAC and
KEK B factories is given. In addition, the measurements of sin(2beta) with
several other modes are described, including B to phi KS, which, as the leading
contribution is from a loop diagram, could be sensitive to physics beyond the
Standard Model.


title:
Measurement of the open-charm contribution to the diffractive proton
  structure function

abstract:
  Production of D*+/-(2010) mesons in diffractive deep inelastic scattering has
been measured with the ZEUS detector at HERA using an integrated luminosity of
82 pb^{-1}. Diffractive events were identified by the presence of a large
rapidity gap in the final state. Differential cross sections have been measured
in the kinematic region 1.5 < Q^2 < 200 GeV^2, 0.02 < y < 0.7, x_{IP} < 0.035,
beta < 0.8, p_T(D*+/-) > 1.5 GeV and |\eta(D*+/-)| < 1.5. The measured cross
sections are compared to theoretical predictions. The results are presented in
terms of the open-charm contribution to the diffractive proton structure
function. The data demonstrate a strong sensitivity to the diffractive parton
densities.


title: Observation of Atmospheric Neutrino Oscillations in Soudan 2

abstract:
  The effects of oscillations of atmospheric muon neutrinos are observed in the
5.90 fiducial kiloton-year exposure of the Soudan 2 detector. An unbinned
maximum likelihood analysis of the neutrino L/E distribution has been carried
out using the Feldman-Cousins prescription. The probability of the no
oscillation hypothesis is 5.8x10-4. The 90% confidence allowed region in the
sin**(2theta), Delta m**2 plane is presented.


title:
A search for periodic modulations of the solar neutrino flux in
  Super-Kamiokande-I

abstract:
  A search for periodic modulations of the solar neutrino flux was performed
using the Super-Kamiokande-I data taken from May 31st, 1996 to July 15th, 2001.
The detector's capability of measuring the exact time of events, combined with
a relatively high yield of solar neutrino events, allows a search for
short-time variations in the observed flux. We employed the Lomb test to look
for periodic modulations of the observed solar neutrino flux. The obtained
periodogram is consistent with statistical fluctuation and no significant
periodicity was found.


title: The virtual photon structure at HERA

abstract:
  An overview is given of the ongoing measurement at HERA of the parton
structure of the photon, as a function of its virtuality. Preliminary ZEUS
results show disagreement with an NLO QCD calculation.

  A brief survey is given of recent HERA results in jet production and prompt
photon production, together with the evaluation of the QCD coupling constant
alpha_s.

A preliminary Measurement of Hadronic Mass Moments in Semileptonic B
  Meson Decays

abstract:
  A preliminary measurement of the second moments of the hadron mass in B --> X
l nu decays by the BABAR Collaboration is reported. These measurements are
performed as a function of the lepton momentum above a given threshold.


title: Observation of $B^{\pm} \to D_{CP}K^{*\pm}$ Decays

abstract:
  We report preliminary results on the decay $B^{-} \to D^{0}K^{*-}$, $B^{-}
\to D_{CP}K^{*-}$ and its charge c onjugate using a data sample of 95.8 million
$B\bar{B}$ pairs recorded at the $\Upsilon(4S)$ resonance with the Belle d
etector at the KEKB asymmetric $e^{+}e^{-}$ storage ring. We find the branching
fraction for $B^{-} \to D^{0} K^{*-}$ to be ${\cal B} = (5.2 \pm 0.5(stat) \pm
0.6(sys)) \times 10^{-4}$ and the partial-rate charge asymmetries for $B^{-}
\rig htarrow D_{CP}K^{*-}$ to be ${\cal{A}}_1 = -0.02 \pm 0.33(stat) \pm
0.07(sys)$ and ${\cal{A}}_2 = 0.19 \pm 0.50(stat) \pm 0.0 4(sys)$ where the
indices 1 and 2 represent the CP=+1 and CP=$-$1 eigenstates of the
$D^{0}-\bar{D^{0}}$ system, respectively .


title: Evidence for B^+ -> omega l^+ nu

abstract:
  We have searched for the decay B^+ -> omega l^+ nu in 78 fb^-1 of Y(4S) data
(85.0 million BBbar events) accumulated with the Belle detector. The final
state is fully reconstructed using the omega decay into pi^+ pi^- pi^0 and
detector hermeticity to estimate the neutrino momentum. 155 +/- 47 signal
events are found in the data, corresponding to a branching fraction of (1.3 +/-
0.4 +/- 0.2 +/- 0.3) x 10^-4, where the first two errors are statistical and
systematic. The third error is due to the estimated form-factor uncertainty.
(This result is preliminary.)


title: $K_{l3}$ prospects from NA48/2

abstract:
  NA48/2 plans for the $K_{e3}$ and $K_{\mu 3}$ branching ratios and Dalitz
plots measurements are discussed. The relative errors for the branching ratios
$< 1%$ are expected.


title:
Studies of $B^0 \to \rho^\pm \pi^\mp$ and Evidence of $B^0 \to \rho^0
  \pi^0$

abstract:
  We report studies of $B^0 \to \pi^+ \pi^- \pi^0$, using $78 {\rm fb}^{-1}$ of
data collected at the $\Upsilon(4S)$ resonance with the Belle detector at the
KEKB asymmetric $e^+e^-$ storage ring. We measure the branching fraction for
$B^0 \to \rho^\pm \pi^\mp$ to be ${\mathcal B}(B^0 \to \rho^\pm \pi^\mp) =
(29.1 ^{+5.0}_{-4.9}({\rm stat}) \pm 4.0({\rm syst})) \times 10^{-6}$, and find
an untagged charge asymmetry ${\mathcal A} = -0.38^{+0.19}_{-0.21} ({\rm stat})
^{+0.04}_{-0.05} ({\rm syst})$. We find the first evidence for $B^0 \to \rho^0
\pi^0$ with $3.1\sigma$ statistical significance and with a branching fraction
of ${\mathcal B}(B^0 \to \rho^0\pi^0) = (6.0 ^{+2.9}_{-2.3} ({\rm stat}) \pm
1.2 ({\rm syst})) \times 10^{-6}$.


title: The Trigger of the ATLAS Experiment

abstract:
  With the high bunch-crossing and interaction rates and potentially large
event sizes the experiments at the LHC challenge data acquisition and trigger
systems. Within the ATLAS experiment, a multi-level trigger system based on
hardware and software is employed to cope with the task of event-rate
reduction. This review article gives an overview of the trigger of the ATLAS
experiment highlighting the design principles and the implementation of the
system and provides references to more detailed information. In addition, first
trigger- performance studies and an outlook on the ATLAS event-selection
strategy are presented.


title:
Search for Narrow t-tbar Resonances in ppbar Collisions at \root{s} =
  1.8 TeV

abstract:
  A search for narrow resonances that decay into t-tbar pairs has been
performed using 130 pb^{-1} of data in the lepton+jets channel collected in
p-pbar collisions at \sqrt{s} = 1.8 TeV. There is no significant deviation
observed from the standard model, and upper limits at the 95 % confidence level
on the product of the production cross section and branching fraction to t-tbar
are presented for narrow resonances as a function of the resonance mass M_X.
These limits are used to exclude the existence of a leptophobic topcolor
particle with mass M_X < 560 GeV/c^2 and width \Gamma_X = 0.012 M_X.


title:
Measurement of Prompt Charm Meson Production Cross Sections in p anti-p
  Collisions at s**(1/2) = 1.96 TeV

abstract:
  We report on measurements of differential cross sections d sigma/d p_t for
prompt charm meson production in p anti-p collisions at s**(1/2) = 1.96 TeV
using 5.8 +/- 0.3 pb-1 of data from the CDF II detector at the Fermilab
Tevatron. The data are collected with a new trigger that is sensitive to the
long lifetime of hadrons containing heavy flavor. The charm meson cross
sections are measured in the central rapidity region |y| \leq 1 in four fully
reconstructed decay modes: D0 --> K- pi+, D*+ -> D0 pi+, D+ --> K- pi+ pi+,
D+_s--> phi pi+, and their charge conjugates. The measured cross sections are
compared to theoretical calculations.


title: Measurement of Hadronic Recoil Mass Moments in Semileptonic B Decay

abstract:
  We present a preliminary measurement of the composition of inclusive
semileptonic B meson decays using 9.4 fb^{-1} of e^+e^- data taken with the
CLEO detector at the Upsilon(4S) resonance. In addition to measuring the
charged lepton kinematics, the neutrino four-vector is inferred using the
hermeticity of the detector. We perform a maximum likelihood fit over the full
three-dimensional differential decay distribution for the fractional
contributions from the B->X_c l nu processes with X_c = D, D^*, D^**, and
non-resonant X_c, and the process B -> X_u l nu. From the fit results we
extract <M_X2 - M_D[Bar]^2> = (0.456 +- 0.014 +- 0.045 +- 0.109) GeV^2/c^4 with
minimum lepton energy of 1.0 GeV and <M_X2 - M_D[Bar]^2> (0.293 +- 0.012 +-
0.033 +- 0.048) GeV^2/c^4 with minimum lepton energy of 1.5 GeV. The
uncertainties are from statistics, detector systematic effects, and model
dependence, respectively.


title: Study of B meson decays to three-body charmless hadronic final states

abstract:
  We report results of a study of charmless B meson decays to three-body KPiPi,
KKPi and KKK final states. Measurements of branching fractions for B decays to
K+0Pi+Pi-, K+K+K-, K0K+K-, KsKsK+ and KsKsKs final states are presented. The
decays B0=>K0K+K-, B+=>KsKsK+ and B0=>KsKsKs are observed for the first time.
We also report evidence for B+=>K+K-Pi+ decay. For the three-body final states
K0K+K-, KsKsPi+, K+K+Pi- and K-Pi+Pi+ 90% confidence level upper limits are
reported. Finally, we discuss the possibility of using the three-body
B0=>KsK+K- decay for CP violation studies. The results are obtained with a 78
fb^-1 data sample collected at the Y(4S) resonance by the Belle detector
operating at the KEKB asymmetric energy e+e- collider.


title:
Evidence for the positive-strangeness pentaquark $\Theta^+$ in
  photoproduction with the SAPHIR detector at ELSA

abstract:
  The positive--strangeness baryon resonance $\Theta^+$ is observed in
photoproduction of the $\rm nK^+K^0_s$ final state with the SAPHIR detector at
the Bonn ELectron Stretcher Accelerator ELSA. It is seen as a peak in the $\rm
nK^+$ invariant mass distribution with a $4.8\sigma$ confidence level. We find
a mass $\rm M_{\Theta^+} = 1540\pm 4\pm 2$ MeV and an upper limit of the width
$\rm \Gamma_{\Theta^+} < 25$ MeV at 90% c.l. From the absence of a signal in
the $\rm pK^+$ invariant mass distribution in $\rm\gamma p\to pK^+K^-$ at the
expected strength we conclude that the $\Theta^+$ must be isoscalar.


title: Measurement of the e+e- --> D(*)+D(*)- cross-sections

abstract:
  In this paper we report the first measurement of $e^+e^- \to
D^{(*)+}D^{(*)-}$ processes. The cross-sections for $e^+^e- \to D^{*+}D^{*-}$
and $e^+e^- \to D^+D^{*-}$ at $\sqrt{s}=10.58\mathrm{GeV}/c^2$ have been
measured to be $0.65 \pm 0.04 \pm 0.07 \mathrm{pb}$ and $0.71 \pm 0.05 \pm 0.09
\mathrm{pb}$, respectively. We set an upper limit on the cross-section of e+e-
--> D+ D- of $0.04 \mathrm{pb}$ at the 90% confidence level. In addition we
have measured the fraction of the $D^{*\pm}_T D^{*\mp}_L$ final state in the
e+e- --> D*+ D*- reaction to be $(97\pm 5)%$. The analysis is performed using
$88.9 \mathrm{fb}^{-1}$ of data collected by the Belle detector at the
$e^{+}e^{-}$ asymmetric collider KEKB.


title: First results from the NA60 experiment at CERN

abstract:
  Since 1986, several heavy ion experiments have studied some signatures of the
formation of the quark-gluon plasma and a few exciting results have been found.
However, some important questions are still unanswered and require new
measurements. The NA60 experiment, with a new detector concept that vastly
improves dimuon detection in proton-nucleus and heavy-ion collisions, studies
several of those open questions, including the production of open charm. This
paper presents the experiment and some first results from data collected in
2002.


title: Search for Rare Charm Meson Decays at FNAL E791

abstract:
  We report the results of a blind search for flavor-changing neutral current
(FCNC), lepton-flavor violating, and lepton-number violating decays of D+, Ds+,
and D0 mesons (and their antiparticles) into 2-, 3-, and 4-body states
including a lepton pair. Such decays may involve Flavor-Changing Neutral
Currents, Leptoquarks, Horizontal Gauge Bosons, or Majorana Neutrinos. No
evidence for any of these decays is found. Therefore, we present 90% confidence
level branching fraction upper limits, typically at the 0.0001 level. A total
of 51 decay channels have been examined; 26 have not been previously reported
and 18 are significant improvements over previous results.


title:
Measurement of Branching Fractions and CP-Violating Charge Asymmetries
  in B+ --> rho+ pi0 and B+ --> rho0 pi+, and Search for B0 --> rho0 pi0

abstract:
  We present preliminary measurements of branching fractions and CP-violating
charge asymmetries in B-meson decays to rho pi. The data sample comprises 89
million Y(4S) --> BBbar decays collected with the BABAR detector at the PEP-II
asymmetric-energy B Factory at SLAC. We find the charge-averaged branching
fractions B(B+ --> rho+ pi0) = (11.0 +/- 1.9(stat.) +/- 1.9(syst.)) * 10^-6 and
B(B+ --> rho0 pi+) = (9.3 +/-1.0(stat.) +/- 0.8(syst.)) * 10^-6; we set a 90%
confidence-level upper limit of B(B0 --> rho0 pi0) < 2.5 * 10^-6. We measure
the CP-violating charge asymmetries A_CP(rho+ pi0) = 0.23 +/- 0.16(stat.) +/-
0.06(syst.) and A_CP(rho0 pi+) = -0.17 +/- 0.11(stat.) +/- 0.02(syst.).


title:
Evidence for an Exotic Baryon State, Theta+(1540), in Photoproduction
  Reactions from Protons and Deuterons with CLAS

abstract:
  CLAS photoproduction data on deuterium and hydrogen targets have been
analyzed in a search for an exotic baryon state with strangeness S=+1, the
\Theta^+ (originally named the Z^+). This resonance was predicted recently in
theoretical work based on the chiral soliton model as a lowest mass member of
an anti-decuplet of 5-quark states. The reaction gamma d --> pK^-K^+n, which
requires a final state interaction inside the deuteron, was used in the
analysis of deuteron data. In the analysis of proton data, the reaction gamma p
--> pi^+K^-K^+n was studied. Evidence for the \Theta^+ state is found in both
analyses in the invariant mass distribution of the nK^+. Our results are
consistent with previously reported results by LEPS/Spring-8 collaboration
(Japan), and by the ITEP (Moscow) group.


title: J/Psi Polarization in 800-GeV p-Cu Interactions

abstract:
  We present measurements of the polarization of the $ J/\psi $ produced in
800-GeV proton interactions with a copper target. Polarization of the $ J/\psi
$ is sensitive to the $ c \bar{c} $ production and hadronization processes. A
longitudinal polarization is observed at large $ x_{F} $, while at small $
x_{F} $ the state is produced essentially unpolarized or slightly transversely
polarized. No significant variation of the polarization is observed versus $
p_{T} $.


title:
Energy dependence of transverse mass spectra of kaons produced in p+p
  and p+pbar interactions.A compilation

abstract:
  The data on m_T spectra of K0S K+ and K- mesons produced in all inelastic p+p
and p+pbar interactions in the energy range sqrt(s)NN=4.7-1800GeV are compiled
and analyzed. The spectra are parameterized by a single exponential function,
dN/(m_T*dm_T)=C exp(-m_T/T), and the inverse slope parameter T is the main
object of study. The T parameter is found to be similar for K0S, K+ and K-
mesons. It increases monotonically with collision energy from T~30MeV at
sqrt(s)NN=4.7GeV to T~220MeV at sqrt(s)NN=1800GeV. The T parameter measured in
p+p and p+pbar interactions is significantly lower than the corresponding
parameter obtained for central Pb+Pb collisions at all studied energies. Also
the shape of the energy dependence of $T$ is different for central Pb+Pb
collisions and p+p(pbar) interactions.


title: Brief physics survey with CMS in year one

abstract:
  The CMS detector is one of the two general purpose experiments that will
study the collisions produced by the Large Hadron Collider (LHC). The LHC is
supposed to start its operation in 2007 at an instantaneous luminosity of 2 x
10^33 cm-2 s-1, which may well result in an integrated luminosity of 10 fb-1
after the first year of running. The corresponding physics reach of CMS is
exemplified with the study of a few standard model channels (weak boson and top
quark production) and with the searches for Higgs bosons.

  We calculate the total and differential quasielastic cross sections for
neutrino and antineutrino scattering on nucleons using up to date fits to the
nucleon elastic electromagnetic form factors $G_E^p$, $G_E^n$, $G_M^p$,
$G_M^n$, and weak and pseudoscalar form factors. We find that using the updated
non-zero value of $G_E^n$ has a significant effect on both the total and
differential neutrino and antineutrino quasielastic cross sections. Previous
extractions of the weak axial form factor from neutrino scattering data are
sensitive to the assumptions that were used for the vector form factors. We
perform a re-analysis of previous neutrino data using updated form factors and
obtain updated value of the axial vector mass.


title: Observation of KsKs resonances in deep inelastic scattering at HERA

abstract:
  Inclusive KsKs production in deep inelastic ep scattering at HERA has been
studied with the ZEUS detector using an integrated luminosity of 120 pb-1. Two
states are observed at masses of 1537 (+9)(-8) MeV and 1726 +- 7 MeV, as well
as an enhancement around 1300 MeV. The state at 1537 MeV is consistent with the
well established f2'(1525). The state at 1726 MeV may be the glueball candidate
f0(1710). However, it's width of 38 (+20)(-14) MeV is narrower than 125 +- 10
MeV observed by previous experiments for the f0(1710).


title: Modeling Neutrino and Electron Scattering Inelastic Cross Sections

abstract:
  We use new scaling variables x_w and xi_w, and add low Q2 modifications to
GRV94 and GRV98 leading order parton distribution functions such that they can
be used to model electron, muon and neutrino inelastic scattering cross
sections (and also photoproduction) at both very low and high energies


title: Reanalysis of Hadronic Cross Section Measurements at CMD-2

abstract:
  The updated results of the precise measurements of the processes
e+e-->rho->pi+pi-, e+e-->omega->pi+pi-pi0 and e+e-->phi->KLKS performed by the
CMD-2 collaboration are presented. The update appeared necessary due an
overestimate of the integrated luminosity in previous analyses.


title: Hadronic Events at LEP

abstract:
  The hadronic events collected by LEP between 1989 and 2000 have changed
dramatically our understanding of QCD, which has now been established as a part
of the Standard Model. Still in many sectors (nonperturbative in particular)
science analysis needs to be completed, and some new studies are just starting.


title: An Experimental Overview of Gluonic Mesons

abstract:
  In this paper, I review the experimental situation for both glueballs and
hybrid mesons. Theoretical expectations are discussed, and a survey of what is
known about hybrid mesons and glueballs is undertaken. Good experimental
evidence exists for both states with exotic quantum numbers and a glueball
which is mixed with the nearby mesons, but a full understanding of these still
requires additional information.


title: Neutrino Physics: Status and Prospects

abstract:
  This pedagogical overview will cover the current status of neutrino physics
from an experimentalist's point of view, focusing primarily on oscillation
studies. The evidence for neutrino oscillations will be presented, along with
the prospects for further refinement of observations in each of the indicated
regions of two-flavor oscillation parameter space. The next steps in
oscillation physics will then be covered (under the assumption of three-flavor
mixing): the quest for $\theta_{13}$, mass hierarchy and, eventually, leptonic
CP violation. Prospects for non-oscillation aspects of neutrino physics, such
as kinematic tests for absolute neutrino mass and double beta decay searches,
will also be discussed briefly.


title: Observation of the Decay $B^{0} \to \pi^{0}\pi^{0}$

abstract:
  We present an observation of the decay $B^{0} \to \pi^{0} \pi^{0}$ based on a
sample of 124 million $B\bar{B}$ pairs recorded by the BABAR detector at the
PEP-II asymmetric-energy $B$ Factory at SLAC. We observe $46 \pm 13 \pm 3$
events, where the first error is statistical and the second is systematic,
corresponding to a significance of 4.2 standard deviations including systematic
uncertainties. We measure the branching fraction $\BR(B^{0} \to \pi^{0}
\pi^{0}) = (2.1 \pm 0.6 \pm 0.3) \times 10^{-6}$, averaged over $B^{0}$ and
$\bar{B}^{0}$ decays.


title: Z Boson Pair-Production at LEP

abstract:
  Events stemming from the pair-production of Z bosons in e^+e^- collisions are
studied using 217.4 pb^-1 of data collected with the L3 detector at
centre-of-mass energies from 200 GeV up to 209 GeV. The special case of events
with b quarks is also investigated.
  Combining these events with those collected at lower centre-of-mass energies,
the Standard Model predictions for the production mechanism are verified. In
addition, limits are set on anomalous couplings of neutral gauge bosons and on
effects of extra space dimensions.


title:
Rare Radiative and Leptonic B Decays: Recent Results from BABAR and
  Belle

abstract:
  Recent BABAR and Belle results on rare B decays involving photons or lepton
pairs are reviewed. New preliminary limits from both experiments for B-->rho
gamma and B-->omega gamma, and from BABAR for B --> K nu nu and B --> tau nu
are presented. Also summarized from the past year are Belle measurements of
B-->Xs l+l- and B0-->K2(1430) gamma, preliminary BABAR measurements of B-->Xs
gamma, and preliminary results from BABAR and Belle on B-->K(*)l+l-. No
significant deviations from Standard Model predictions have yet been found.


title:
Measurement of Branching Fractions and Charge Asymmetries in B Meson
  Decays to eta(') K*, eta{'} rho, and eta' pi

abstract:
  We present preliminary measurements of branching fractions and charge
asymmetries for the B meson decays B -> eta(')K*, B -> eta(')rho, and B+ ->
eta' pi+. The data were recorded with the BaBar detector at PEP-II and
correspond to 89 x 10^6 B B-bar pairs produced in e+e- annihilation through the
Upsilon(4S) resonance. We find the branching fractions B(B0 -> eta K*0) = (19.0
+2.2 -2.1 +/- 1.3) x 10^-6, B(B+ -> eta K*+) = (25.7 +3.8 -3.6 +/- 1.8) x
10^-6, B(B+ -> eta rho+) = (10.5 +3.1 -2.8 +/- 1.3) x 10^-6, B(B+ -> eta' rho+)
= (14.0 +5.1 -4.6 +/- 1.9) x 10^-6 (< 22 x 10^-6 with 90% confidence), and B(B+
-> eta' pi+) = (2.8 +1.3 -1.0 +/- 0.3) x 10^-6 (< 4.5 x 10^-6). We also set 90%
CL upper limits of B(B0 -> eta' K*0) < 6.4 x 10^-6 and B(B+ -> eta' K*+) < 12 x
10^-6. The time-integrated charge asymmetries are Ach(eta K*0) = +0.03 +/- 0.11
+/- 0.02, Ach(eta K*+) = +0.15 +/- 0.14 +/- 0.02, and Ach(eta rho+) = +0.06 +/-
0.29 +/- 0.02.


title:
Measurement of the B --> Xs l+ l- Branching Fraction Using a Sum over
  Exclusive Modes

abstract:
  We present a measurement of the branching fraction for the flavor-changing
neutral current process B --> Xs l+ l- based on a sample of 88.9 \times 10^6
Upsilon(4S) --> BBbar events recorded with the BaBar detector at the PEP-II
e+e- storage ring. The final state is reconstructed from pairs of electrons or
muons and a hadronic system consisting of one K+/- or K0s and up to two pions,
with at most one pi0. Summing over both lepton flavors, we observe a signal of
41 +/- 10(stat) +/- 2(syst) events with a statistical significance of 4.6
sigmas. The inclusive branching fraction is determined to be BF(B --> Xs l+ l-)
= [6.3 +/- 1.6(stat) +1.8 -1.5(syst)] 10^{-6} for m(l+ l-) > 0.2 GeV/c^2. All
results are preliminary.


title:
Measurement of BR(B0 -> Ds*+D*-) and Determination of the Ds+ -> phi pi+
  Branching Fraction with a Partial-Reconstruction Method

abstract:
  We present model-independent measurements of the branching fractions ${\cal
B}(B^0\to D_s^{*+} D^{*-})$ and ${\cal B}(D_s^+ \to \phi \pi^+)$ based on 19.3
$\textup{fb}^{-1}$ of data collected by the $BABAR$ detector at the PEP-II
$e^+e^-$ $B$ Factory. Neutral $B$-meson decays to the $D_s^{*+}D^{*-}$ final
state are selected with a partial reconstruction of the $D_s^{*+}$; that is,
only the $D^{*-}$ and the soft photon from the decay $D_s^{*+} \to \Ds \gamma$
are reconstructed. The branching fraction ${\cal B}(B^0\to D_s^{*+} D^{*-})$ is
extracted from these event yields, while ${\cal B}(D_s^+ \to \phi \pi^+)$ is
determined by combining this result with a previous measurement of the product
${\cal B}(B^0\to D_s^{*+} D^{*-}) \times {\cal B}(D_s^+ \to \phi \pi^+)$ with
partial reconstruction of the $D^{*-}$. We obtain the following preliminary
results:
  ${\cal B}(B^0\to D_s^{*+} D^{*-}) = (1.50 \pm 0.16 \pm 0.12)%,$
  ${\cal B}(D_s^+ \to \phi \pi^+) = (4.7 \pm 0.6 \pm 0.8)%$ where the first
error is statistical, and the second systematic.


title:
Measurement of Time-Dependent CP Asymmetry in B0->D^(*)+-pi-+ Decays and
  Constraints on |sin(2beta+gamma)|

abstract:
  We present preliminary results of a time-dependent measurement of
CP-violating asymmetry in fully reconstructed B0->D^(*)+-pi-+ decays in a data
sample of approximately 88 million Y(4S)->BB decays collected with the BaBar
detector at the PEP-II asymmetric-energy B factory at SLAC. We interpret the
results in terms of the angles of the Cabibbo-Kobayashi-Maskawa unitarity
triangle, and set the bound |sin(2beta+gamma)|>0.69 at 68% confidence level. We
exclude sin(2beta+gamma) = 0 at 83% confidence level.


title: Observation of the DsJ(2317) and DsJ(2457) in B decays

abstract:
  We report the first observation of the B --> Dbar DsJ(2317) and B --> Dbar
DsJ(2457) decays based on 123.8 10^6 BBar events collected with the Belle
detector at KEKB. We observe the DsJ(2317) decay to Ds pi0 and DsJ(2457) decay
to the Ds* pi0 and Ds gamma final states. We also set 90% CL upper limits for
the decays DsJ(2317) --> Ds* gamma, DsJ(2457) --> Ds* gamma, DsJ(2457) --> Ds
pi0 and DsJ(2457) --> Ds pi+ pi-.


title:
A Measurement of the Total Width, the Electronic Width and the Mass of
  the Upsilon(10580) Resonance

abstract:
  We present a preliminary measurement of the resonance parameters of the
Upsilon(10580) resonance with the BABAR detector at the SLAC PEP-II asymmetric
B factory. We measure the total decay width to be (20.7 +- 1.6 +- 2.5) MeV, the
partial electronic width to be (0.321 +- 0.017 +- 0.029) kev and the mass to be
(10.5793 +- 0.0004 +- 0.0012) GeV.


title:
Measurement of Branching Fractions for B0 ->K*2(1430)0 gamma and B+ ->
  K*2(1430)+ gamma

abstract:
  We have investigated the exclusive, radiative B-meson decay to K_2^*(1430) in
88.5 * 10^6 BBbar events. We present a preliminary measurement of the branching
fractions BR(B->K^*_2(1430)^0 gamma) = (1.22+-0.25+-0.11) * 10^{-5} and
BR(B->K^*_2(1430)^+ gamma) = (1.44+-0.40+-0.13) * 10^{-5}.


title:
Production of pizero and eta mesons at large transverse momenta in pi-p
  and pi-Be interactions at 515 GeV/c

abstract:
  We present results on the production of high transverse momentum pizero and
eta mesons in pi-p and pi-Be interactions at 515 GeV/c. The data span the
kinematic ranges 1 < p_T < 11 GeV/c in transverse momentum and -0.75 < y < 0.75
in rapidity. The inclusive pizero cross sections are compared with
next-to-leading order QCD calculations and to expectations based on a
phenomenological parton-k_T model.


title: Recent results from the KLOE experiment at DA$\Phi$NE

abstract:
  The KLOE experiment at DA$\Phi$NE collected about 450 pb$^-1$ of data in
2001--2002. Much of this data set has been analyzed and has yielded definitive
results on $K_S$ and radiative $\phi$ decays, as well as studies concerning a
wide range of topics in kaon and hadronic physics.


title:
Observation of the Decay B0->rho+rho- and Measurement of the Branching
  Fraction and Polarization

abstract:
  We have observed the rare decay B0->rho+rho- in a sample of 89 million BBbar
pairs recorded with the BABAR detector. We measure the branching fraction
B(B0->rho+rho-)=(27+7-6+5-7)10^-6 and determine the longitudinal polarization
fraction Gamma_L/Gamma=0.99+0.01-0.07+-0.03. Our results are preliminary.


title: The chemical history of $^{14}{\rm C}$ in deep oilfields

abstract:
  14C is an overwhelming background in low-background underground experiments,
to the point where the observation of the all-important (pp) neutrinos from the
Sun can not be observed in carbon-containing experiments. This paper shows that
14C purity can be improved by four orders of magnitude by a careful selection
of the gas field. Two large reduction factors are at work: the low chemical
affinity of methane to single carbon, and the migration of natural gas away
from nitrogen-bearing kerogen during as the oilfield matures.


title: Study of the Decays B- -> D(*)+ pi- pi-

abstract:
  We report on analyses of $B^-$ mesons decaying into $D^{*+}\pi^-\pi^-$ and
$D^+\pi^-\pi^-$ final states using 89 million $B^-$ decays collected by the
BABAR detector at the PEP-II asymmetric-energy $B$ Factory. Preliminary
measurements are given for the inclusive branching fractions for $B^- \to
D^{*+}\pi^-\pi^-$ and $B^- \to D^+\pi^-\pi^-$, and for the exclusive branching
fractions for $B^- \to D_1(2420)^0\pi^-$ and $B^- \to D_2^{*}(2460)^0\pi^-$,
where $D_1(2420)^0$ and $D_2^{*}(2460)^0$ are the two narrow $c\bar u$ $P$-wave
states. The ratio ${\mathcal{B}}(B^- \to D_2^*(2460)^0\pi^-)/{\mathcal{B}}(B^-
\to D_1(2420)^0\pi^-)$ is measured to be $0.80 \pm 0.07 \pm 0.16$.


title: Measurement of |Vcb| using B0 -> D* l nu_l Decays

abstract:
  A preliminary measurement of |Vcb| and the branching fraction BR(B0 -> D* l
nu_l) has been performed based on a sample of about 55,700 B0 -> D* l nu_l
decays recorded with the BaBar detector. The decays are identified in the D* ->
D0 pi final state, with the D0 reconstructed in three different decay modes.
The differential decay rate is measured as a function of the relativistic boost
of the D* in the B0 rest frame. The value of the differential decay rate at
`zero recoil', namely the point at which the D* is at rest in the B0 frame, is
predicted in Heavy Quark Effective Theory as a kinematic factor times
F(1)|Vcb|, where F(1) is the unique form factor governing the decay. We
extrapolate the measured differential decay rate to the zero recoil point and
obtain F(1)|Vcb|=(34.03+-0.24+-1.31) x 10^-3. Using a theoretical calculation
for F(1) we extract |Vcb| = (37.27+-0.26(stat.)+-1.43(syst.)+1.5-1.2(theo.) x
10^-3. From the integrated decay rate we obtain BR(B0 -> D* l nu_l) =
(4.68+-0.03+-0.29)%.


title: Future Accelerators (?)

abstract:
  I describe the future accelerator facilities that are currently foreseen for
electroweak scale physics, neutrino physics, and nuclear structure. I will
explore the physics justification for these machines, and suggest how the case
for future accelerators can be made.


title:
Observation of a New Narrow Charmonium State in Exclusive B+-->K+ pi+pi-
  J/psi Decays

abstract:
  We report the first observation of a narrow charmmonium state produced in the
exclusive decay process B+->K+ pi+pi- J/psi. This state, which decays into
pi+pi-J/psi, has a mass of 3871.8+-0.7(stat)+-0.4(syst) MeV, which is very near
the M_D + M_D* mass threshold. The results are based on an analysis of 152M
BBbar events collected at the Upsilon(4S) resonance in the Belle detector at
the KEKB collider.


title: Precision Measurement of Orthopositronium Decay Rate Using SiO_2 Powder

abstract:
  The intrinsic decay rate of orthopositronium formed in ${\rm SiO_2}$ powder
is measured using the direct $2\gamma$ correction method such that the time
dependence of the pick-off annihilation rate is precisely determined using high
energy-resolution germanium detectors. As a systematic test, two different
types of ${\rm SiO_2}$ powder are used with consistent findings. The intrinsic
decay rate of orthopositronium is found to be $7.0396\pm0.0012 (stat.)\pm0.0011
(sys.)\mu s^{-1}$, which is consistent with previous measurements using ${\rm
SiO_2}$ powder with about twice the accuracy. Results agree well with a recent
$O(\alpha^2)$ QED prediction, varying $3.8-5.6$ experimental standard
deviations from other measurements.


title: Solution of Orthopositronium lifetime Puzzle

abstract:
  The intrinsic decay rate of orthopositronium formed in ${\rm SiO_2}$ powder
is measured using the direct $2\gamma$ correction method such that the time
dependence of the pick-off annihilation rate is precisely determined. The decay
rate of orthopositronium is found to be $7.0396\pm0.0012 (stat.)\pm0.0011
(sys.)\mu s^{-1}$, which is consistent with our previous measurements with
about twice the accuracy. Results agree well with the $O(\alpha^2)$ QED
prediction, and also with a result reported very recently using nanoporous
film.


title:
Observation of Diffractively Produced W and Z Bosons in pbar-p
  Collisions at root-s = 1800 GeV

abstract:
  Using the D0 detector, we have observed events produced in pbar-p collisions
that contain W or Z bosons in conjunction with very little energy deposition
(``rapidity gaps'') in large forward regions of the detector. The fraction of W
boson events with a rapidity gap (a signature for diffraction) is
0.89\pm^{0.19}_{0.17}%, and the probability that the non-diffractive background
fluctuated to yield the observed diffractive signal is 3 x 10^{-14},
corresponding to a significance of 7.5 sigma. The Z boson sample has a gap
fraction of 1.44 \pm^{0.61}_{0.52}%, with a significance of 4.4 sigma. The
diffractive events have very similar properties to the more common
non-diffractive component.


title:
Search for New Particles in the Two-Jet Decay Channel with the D0
  Detector

abstract:
  We present the results of a search for the production of new particles
decaying into two jets in pbarp collisions at sqrt{s} = 1.8 TeV, using the
DZero 1992-1995 data set corresponding to 109 pb^-1. We exclude at the 95%
confidence level the production of excited quarks (q*) with masses below 775
GeV/c^2, the most restictive limit to date. We also exclude standard-model-like
W' (Z') bosons with masses between 300 and 800 GeV/c^2 (400 and 640 GeV/c^2). A
W' boson with mass $<$ 300 GeV/c^2 has been excluded by previous measurements,
and our lower limit is therefore the most stringent to date.


title:
Measurement of the D0 - anti-D0 lifetime difference using D0 -> Kpi/KK
  decays

abstract:
  We report a preliminary measurement of the D0-anti-D0 mixing parameter y_CP
and the CP-violating parameter A_G using the decay D*+ -> D0 pi+ followed by D0
-> K- pi+ and D0 -> K+ K-. The results are obtained from a 158 fb^-1 data
sample collected near the Upsilon(4S) resonance with the Belle detector at the
KEKB asymmetric energy e+ e- collider.


title:
Measurement of Time-Dependent CP-Violating Asymmetries in B0 --> phi
  Ks0, K+ K- Ks0, and eta' Ks0 Decays

abstract:
  We present an improved measurement of CP-violation parameters in B0 --> phi
Ks0, K+ K- Ks0, and eta' Ks0 decays based on a 140 fb-1 data sample collected
at the Upsilon(4S) resonance with the Belle detector at the KEKB
energy-asymmetric e+e- collider. One neutral B meson is fully reconstructed in
one of the specified decay channels, and the flavor of the accompanying B meson
is identified from its decay products. CP-violation parameters for each of the
three modes are obtained from the asymmetries in the distributions of the
proper-time intervals between the two B decays. We find that the observed CP
asymmetry in the B0 --> phi Ks0 decay differs from the standard model (SM)
expectation by 3.5 standard deviations, while the other cases are consistent
with the SM.


title:
Measurement of CP-Violation Parameter sin(2phi1) with 152 Million BB-bar
  Pairs

abstract:
  We present a precise measurement of the standard model CP-violation parameter
sin(2phi1) based on a sample of 152 x 10^6 BB-bar pairs collected at the
Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy
e+e- collider. One neutral B meson is reconstructed in a J/psi Ks0, psi(2S)
Ks0, chi_c1 Ks0, eta_c Ks0, J/psi K*0, or J/psi KL CP-eigenstate decay channel
and the flavor of the accompanying B meson is identified from its decay
products. From the asymmetry in the distribution of the time interval between
the two B meson decay points, we obtain sin(2phi1) = 0.733 +/- 0.057(stat) +/-
0.028(syst).


title: Observation of Radiative Decay $D^0 \to \phi \gamma$

abstract:
  We report the observation of the decay $D^{0} \to \phi \gamma$ with a
statistical significance of $5.4\sigma$ in $78.1 \ifb$ of data collected by the
Belle experiment at the KEKB $e^+ e^-$ collider. This is the first observation
of a flavor-changing radiative decay of a charmed meson. The Cabibbo- and
color-suppressed decays $D^0 \to \phi \pi^0$, $\phi \eta$ are also observed for
the first time. We measure branching fractions $\br(D^{0} \to \phi \gamma)
  = [ 2.60^{+0.70}_{-0.61} \stat {}^{+0.15}_{-0.17} \syst ] \times 10^{-5}$,
$\br(D^{0} \to \phi \pi^{0})
  = [ 8.01 \pm 0.26 \stat \pm 0.47 \syst ] \times 10^{-4}$, and $\br(D^{0} \to
\phi \eta) = [ 1.48 \pm 0.47 \stat \pm 0.09 \syst ] \times 10^{-4}$.


title: Measurement of the CP Asymmetry in B -> X_s gamma

abstract:
  Direct CP violation in the b->sgamma process is a sensitive probe of physics
beyond the Standard Model. We report a measurement of the CP asymmetry in B ->
X_s gamma, where the hadronic recoil system Xs is reconstructed using a
pseudo-reconstruction technique. In this approach there is negligible
contamination from b->dgamma decays, which are expected to have a much larger
CP asymmetry. We find ACP = 0.002 +- 0.050(stat.) +- 0.030(syst.) for B -> Xs
gamma events having recoil mass smaller than 2.1 GeV/c^2. The analysis is based
on a data sample of 140 /fb recorded at the Upsilon(4S) resonance with the
Belle detector at the KEKB e+e- storage ring.


title: Measurement of Branching Fraction for B --> psi(2S)K*(892) Decays

abstract:
  We have measured the branching fractions of the colour suppressed decays
B^{+} --> \psi(2S) K^{*+}(892) and B^{0} --> psi(2S)K^{*0}(892) using a data
sample of 84 million B\bar{B} events recorded by the Belle detector on the
Upsilon(4S) resonance. The branching fractions for the charged and neutral mode
decays are (8.13 \pm 0.77 \pm 0.89) x 10^{-4}$ and $(7.20 \pm 0.43 \pm 0.65) x
10^{-4}$, respectively.


title: Evidence for B0->pi0pi0

abstract:
  We report evidence for the decay B0->pi0pi0. The analysis is based on a data
sample of 152million BBbar pairs collected at the Upsilon(4s) resonance with
the Belle detector at the KEKB e+e- storage ring. We find
25.6+9.3/-8.4(stat)+1.6/-1.4(syst) B0->pi0pi0 signal events with a significance
of 3.4 standard deviations. We measure the branching fraction to be
(1.7+-0.6(stat)+-0.2(syst))*10^{-6}.


title: Studies of Inclusive Jet Production in ep Interactions at HERA

abstract:
  Inclusive jet production in neutral and charged current deep inelastic
scattering, in photoproduction and the transition region has been studied with
the ZEUS and H1 detectors at HERA. The measurements have been compared to
next-to-leading-order QCD calculations which are used to make determinations of
the strong coupling constant.


title:
Evidence for the Rare Decay B -> K*ll and Measurement of the B -> Kll
  Branching Fraction

abstract:
  We present evidence for the flavor-changing neutral current decay $B\to
K^*\ell^+\ell^-$ and a measurement of the branching fraction for the related
process $B\to K\ell^+\ell^-$, where $\ell^+\ell^-$ is either an $e^+e^-$ or
$\mu^+\mu^-$ pair. These decays are highly suppressed in the Standard Model,
and they are sensitive to contributions from new particles in the intermediate
state. The data sample comprises $123\times 10^6$ $\Upsilon(4S)\to B\bar{B}$
decays collected with the Babar detector at the PEP-II $e^+e^-$ storage ring.
Averaging over $K^{(*)}$ isospin and lepton flavor, we obtain the branching
fractions ${\mathcal B}(B\to K\ell^+\ell^-)=(0.65^{+0.14}_{-0.13}\pm
0.04)\times 10^{-6}$ and ${\mathcal B}(B\to
K^*\ell^+\ell^-)=(0.88^{+0.33}_{-0.29}\pm 0.10)\times 10^{-6}$, where the
uncertainties are statistical and systematic, respectively. The significance of
the $B\to K\ell^+\ell^-$ signal is over $8\sigma$, while for $B\to
K^*\ell^+\ell^-$ it is $3.3\sigma$.


title:
Measurement of the angle \phi_3 with Dalitz analysis of three-body D^0
  decay from B\to D^0 K process

abstract:
  A new method to measure the angle $\phi_3$ of the CKM unitarity triangle
using a Dalitz analysis of the three-body decay of the $D^0$ meson from the
$B\to D^0 K$ process has been introduced recently. The method employs the
interference between $D^0$ and $\bar{D^0}$ to extract both the weak and strong
phases. We present a study of statistical and systematic errors of this method
using Monte Carlo simulation. A fit of the $D^0$ Dalitz distribution has been
performed based on a 140 fb$^{-1}$ sample collected by the Belle detector. We
observe the indication of a CP asymmetry with the significance of 2.4 standard
deviations. The 90% confidence interval obtained for the $\phi_3$ value is
$61^{\circ}<\phi_3<142^{\circ}$.


title: Observation of $B \to K^* \ell^+ \ell^-$

abstract:
  We report the first observation of the flavor-changing neutral current decay
$B \to K^* \ell^+ \ell^-$ and an improved measurement of the decay $B \to K
\ell^+ \ell^-$, where $\ell$ represents an electron or a muon, with a data
sample of 140 fb${}^{-1}$ accumulated at the $\Upsilon(4S)$ resonance with the
Belle detector at KEKB. The results for the branching fractions are ${\cal B}(B
\to K^* \ell^+ \ell^-)=(11.5^{+2.6}_{-2.4} \pm 0.8 \pm 0.2) \times 10^{-7}$ and
${\cal B}(B \to K \ell^+ \ell^-)=(4.8^{+1.0}_{-0.9} \pm 0.3 \pm 0.1) \times
10^{-7}$, where the first error is statistical, the second is systematic and
the third is from model dependence.


title: Experimental Status of b --> s(d) gamma Decays

abstract:
  Radiative penguin decays provide an indirect probe for physics beyond the
Standard Model and contribute to the determination of the CKM matrix elements.
Copious quantities of B mesons produced at the B-Factories permit precision
measurements of radiative penguin decays. We review the experimental status of
the radiative penguin processes b --> s(d) gamma.


title: Recent Results on Light Meson Physics

abstract:
  Some recent results on light meson physics are reviewed. The new evidence of
low mass scalar mesons together with an improved measurement of the phi
radiative decays in scalar mesons, give new insight into the nature and the
structure of the scalar spectrum. The evidence of new states with a mass close
to twice the proton mass, and a new analysis of the gluonium content of the
eta' are discussed.


title: Meson Spectroscopy in Photo-production at CLAS

abstract:
  Photo-production of excited mesons in the 1-2 GeV mass range decaying via
multi-pion or multi-kaon emission has been investigated at the
TJNAF\thanks{This work was supported by the U.S. Department of Energy and The
U.S. National Science Foundation.} experiment E01-017 (g6c) in the $4.8-5.4$
GeV photon beam energy range. The main objective of the experiment is to
extract resonance parameters of the produced states by way of a Partial Wave
Analysis (PWA) technique. In this paper, we will focus on the general
characteristics of the data distributions in both the neutral and charged
3-pion final states, i.e. $\pi^{+}\pi^{-}\pi^{0}$ and $\pi^{+}\pi^{+}\pi^{-}$.


title:
Study of CP Violating Effects in Time Dependent $B^0(\bar{B^0}) \to
  D^{(*)\mp}\pi^{\pm}$ Decays

abstract:
  We report measurements of time dependent decay rates for $B^0(\bar{B}^0) \to
D^{(*)\mp}\pi^{\pm}$ decays and extraction of CP violation parameters
containing $\phi_3$. Using fully reconstructed $D^{(*)}\pi$ events from a $140
{\rm fb}^{-1}$ data sample collected at the $\Upsilon(4S)$ resonance, we obtain
the CP violation parameters for $D^* \pi$ and $D \pi$ decays, $2R_{D^{(*)} \pi}
\sin (2\phi_1 + \phi_3 \pm \delta_{D^{(*)} \pi})$, where $R_{D^{(*)} \pi}$ is
the ratio of the magnitudes of the doubly-Cabibbo-suppressed and
Cabibbo-favoured amplitudes, and $\delta_{D^{(*)} \pi}$ is the strong phase
difference between them. Under the assumption of $\delta_{D^{(*)} \pi}$ being
close to either 0 or $180^{\circ}$, we obtain $|2R_{D^* \pi} \sin (2\phi_1 +
\phi_3)| = 0.060 \pm 0.040(\mathrm{stat}) \pm 0.019(\mathrm{sys})$ and $|2R_{D
\pi} \sin (2\phi_1 + \phi_3)| = 0.061 \pm 0.037(\mathrm{stat}) \pm
0.018(\mathrm{sys})$.


title: Qweak: A Precision Measurement of the Proton's Weak Charge

abstract:
  The Qweak experiment at Jefferson Lab aims to make a 4% measurement of the
parity-violating asymmetry in elastic scattering at very low $Q^2$ of a
longitudinally polarized electron beam on a proton target. The experiment will
measure the weak charge of the proton, and thus the weak mixing angle at low
energy scale, providing a precision test of the Standard Model. Since the value
of the weak mixing angle is approximately 1/4, the weak charge of the proton
$Q_w^p = 1-4 \sin^2 \theta_w$ is suppressed in the Standard Model, making it
especially sensitive to the value of the mixing angle and also to possible new
physics. The experiment is approved to run at JLab, and the construction plan
calls for the hardware to be ready to install in Hall C in 2007. The
theoretical context of the experiment and the status of its design are
discussed.


title:
A study of charm production in beauty decays with the OPAL detector at
  LEP

abstract:
  Using an inclusive method, BR(b -> D\bar{D}X) has been measured in hadronic
Z^0 decays with the OPAL detector at LEP. The impact parameter significance of
tracks opposite tagged b-jets is used to differentiate b -> D\bar{D}X decays
from other decays. Using this result, the average number of charm and
anti-charm quarks produced per beauty quark decay, n_c, is determined.


title:
Measurement of Heavy Quark Forward-Backward Asymmetries and Average B
  Mixing Using Leptons in Hadronic Z Decays

abstract:
  Hadronic Z0 decays with identified electrons or muons have been used to
measure the forward-backward asymmetries of e^+e^- --> Z0 --> bbbar and e^+e^-
--> Z0 --> ccbar events. The asymmetries at three centre-of-mass energies, and
the average B mixing parameter, chi, are determined in a simultaneous fit to
events with one or two lepton candidates.


title:
Search for the Single Production of Doubly-Charged Higgs Bosons and
  Constraints on their Couplings from Bhabha Scattering

abstract:
  A search for single production of doubly-charged Higgs bosons has been
performed using 600.7 pb^-1 of e+e- collision data with sqrt(s)=189--209GeV
collected by the OPAL detector at LEP. No evidence for the existence of H++/--
is observed. Upper limits on the Yukawa coupling of the H++/-- to like-signed
electron pairs are derived. Additionally, indirect constraints on the Yukawa
coupling from Bhabha scattering, where the H++/-- would contribute via
t-channel exchange, are derived for M(H++/--) < 2TeV. These are the first
results for both a single production search and constraints from Bhabha
scattering reported from LEP.


title: Study of time-dependent CP-violation in $B^0 \to J/\psi ~\pi^0$ decay

abstract:
  We report a measurement of CP asymmetry parameters in the $b \to
c\bar{c}d$-transition-induced decays $B^0(\bar{B^0}) \to J/\psi pi^0$. The
analysis is based on a 140 fb$^{-1}$ data sample accumulated at the
$\Upsilon(4S)$ resonance by the Belle detector at the KEKB asymmetric-energy
$e^+ e^-$ collider. We fully reconstruct one neutral $B$ meson in the $J/\psi
~\pi^0$ final state. The accompanying $B$ meson flavor is identified by its
decay products. From the distribution of proper time intervals between the two
B decays, we obtain the following CP violation parameters: S(J/\psi \pi^0)=
-0.72 \pm0.42 (stat) \pm 0.08(syst) A(J/\psi \pi^0)= -0.01 \pm0.29 (stat) \pm
0.07(syst).


title: Study of the decay mode D^0 -> K-K-K+pi+

abstract:
  Using data from the FOCUS (E831) experiment at Fermilab, we present a new
measurement of the branching ratio for the Cabibbo-favored decay mode $D^0 \to
K^-K^-K^+\pi^+$. From a sample of $143 \pm 19$ fully reconstructed $D^0 \to
K^-K^-K^+\pi^+$ events, we measure $\Gamma(D^0 \to K^-K^-K^+\pi^+)/\Gamma(D^0
\to K^-\pi^-\pi^+\pi^+) = 0.00257 \pm 0.00034(stat.) \pm 0.00024(syst.)$.
  A coherent amplitude analysis has been performed to determine the resonant
substructure of this decay mode. This analysis reveals a dominant contribution
from $\phi$ and $\bar K^{*0}(890)$ states.


title:
Interference Study of the chi_c0 (1^3P_0) in the Reaction
  Proton-Antiproton -> pi^0 pi^0

abstract:
  Fermilab experiment E835 has observed proton-antiproton annihilation
production of the charmonium state chi_c0 and its subsequent decay into pi^0
pi^0. Although the resonant amplitude is an order of magnitude smaller than
that of the non-resonant continuum production of pi^0 pi^0, an enhanced
interference signal is evident. A partial wave expansion is used to extract
physics parameters. The amplitudes J=0 and 2, of comparable strength, dominate
the expansion. Both are accessed by L=1 in the entrance proton-antiproton
channel. The product of the input and output branching fractions is determined
to be B(pbar p -> chi_c0) x B(chi_c0 -> pi^0 pi^0)= (5.09 +- 0.81 +- 0.25) x
10^-7.


title: Beauty Quark Production in Deep Inelastic Scattering at HERA

abstract:
  The measurement of the beauty quark production cross section in deep
inelastic scattering with the ZEUS detector at HERA is presented. The cross
section for beauty quarks, measured in the kinematic range $Q^2 > 2$ GeV$^2$
and $0.05 < y < 0.7$, and for events with at least one muon and one jet in the
Breit frame, is somewhat above the next-to-leading order (NLO) QCD prediction,
but in agreement within the experimental and theoretical uncertainties.


title:
Measurement of the Branching Fraction and Polarization for the Decay B-
  to D*0 K*-

abstract:
  We present a study of the decay B- -> D*0 K*- based on a sample of 86 million
Upsilon(4S) -> BBbar decays collected between 1999 and 2002 with the BaBar
detector at the PEP-II asymmetric-energy B-Factory at SLAC. We measure the
branching fraction B(B- -> D*0 K*-) = 8.3 +/- 1.1 (stat)} +/- 1.0 (syst) x
10e-4, and the fraction of longitudinal polarization in this decay to be
GammaL/Gamma = 0.86 +/- 0.06 +/- (stat) +/- 0.03 (syst).


title: Search for single-top production with the ZEUS detector at HERA

abstract:
  A search for anomalous single-top production, ep -> etX, t -> Wb, has been
made with the ZEUS detector at HERA using an integrated luminosity of 130
pb^-1. No evidence for top-quark production was found in either the leptonic or
the hadronic decay channel of the W boson. The resulting constraints on
single-top production via quark-flavour changing neutral current (FCNC)
transitions exclude a substantial region in the FCNC t-u-gamma coupling not
ruled out by other experiments.


title:
Search for the Flavor-Changing Neutral Current Decay D^0\to\mu^+\mu^- in
  p\bar{p} Collisions at \sqrt{s}=1.96 TeV

abstract:
  We report on a search for the flavor-changing neutral current decay
D^0\to\mu^+\mu^- in p\bar{p} collisions at \sqrt{s}=1.96 TeV using 65\ipb of
data collected by the CDF II experiment at the Fermilab Tevatron Collider. A
displaced-track trigger selects long-lived D^0 candidates in the
D^0\to\mu^+\mu^- search channel, the kinematically similar D^0\to\pi^+\pi^-
channel used for normalization, the Cabbibo-favored D^0\to K^+\pi^- channel
used to optimize the selection criteria in an unbiased manner, and their charge
conjugates. Finding no signal events in the D^0\to\mu^+\mu^- search window, we
set an upper limit on the branching fraction {\cal B}(D^0\to\mu^+\mu^-)\leq
2.5E-6 (3.3E-6) at the 90% (95%) confidence level.


title: Measurement of CKM Elements and the Unitarity Triangle

abstract:
  An overview of experimental determinations of different CKM elements is given
with an emphasis on |Vub| and |Vcb| extraction. Measurements are compared to
the Standard Model predictions and constraints on the unitarity triangle,
arising from combination of measurements, are presented.


title: Search for light pseudoscalar sgoldstino in K- decays

abstract:
  A search for the light pseudoscalar sgoldstino production in the three body
K- decay K-->pipi0P has been performed with the ISTRA+ detector exposed to the
25 GeV negative secondary beam of the U70 proton synchrotron. No signal is
seen. An upper limit for the branching ratio Br(K->pipi0P), at 90% confidence
level, is found to be around 9*10**-6 in the effective mass m(P) range from 0
till 200 MeV, excluding the region near m(pi0) where it degrades to 3.5*10**-5.


title:
Is the Unitarity of the Quark-Mixing-CKM-Matrix Violated in Neutron
  Decay?

abstract:
  Measurements by various international groups of researchers determine the
strength of the weak interaction of the neutron, which gives us unique
information on the question of the quark mixing. Neutron decay experiments now
challenge the Standard Model of elementary particle physics with a deviation,
2.7 times the stated error.


title: A New Method For A Sensitive Deuteron EDM Experiment

abstract:
  In this paper a new method is presented for particles in storage rings which
could reach a statistical sensitivity of 10**(-27) e cm for the deuteron EDM.
This implies an improvement of two orders of magnitude over the present best
limits on the T-odd nuclear forces ksi parameter.


title: Precision Measurement of the Anomalous Magnetic Moment of the Muon

abstract:
  A precision measurement of the anomalous magnetic moment (g-2) of the muon
has been made by the E821 collaboration at BNL. This paper is a written version
of a ``hot topics'' talk at ICAP2002 (Cambridge, MA). The principles of the
experiment are discussed, especially the beam dynamics aspects.


title:
Measurements of the Branching Fractions of Charged B Decays to
  K+-pi-+pi+- Final States

abstract:
  We present results of searches for B-meson decays to K+ pi- pi+ with the
BaBar detector. With a data sample of 61.6 million BBbar pairs, we measure the
branching fractions and 90% confidence-level upper limits averaged over
charge-conjugate states (the first error is statistical and the second is
systematic): B+ --> K*0 pi+ = (15.5 +/- 1.8 +1.5 -4.0) x 10^-6, B+ --> f0 K+,
f_0 --> pi+ pi- = (9.2 +/- 1.2 +2.1 -2.6) x 10^-6, B+ --> D0bar pi+, D0bar -->
K+ pi- = (184.6 +/- 3.2 +/- 9.7) x 10^-6. B+ --> rho K+ < 6.2 x 10^-6 and B+
--> K+ pi- pi+ non-resonant < 17 x 10^-6.


title: Prompt Photon Production at HERA

abstract:
  Results are presented on the production of isolated prompt photons in
photoproduction (virtuality Q^2 < 1 GeV^2) and in deep inelastic scattering
(Q^2 > 35 GeV^2). The results are reasonably well described by pQCD
calculations in next to leading order. Comparisons to the Monte Carlo models
PYTHIA and HERWIG are also presented.


title:
Measurement of charged current triple gauge boson couplings using W
  pairs at LEP

abstract:
  Triple gauge boson couplings are measured from W-pair and single photon
events recorded by the OPAL detector at LEP at center-of-mass energies between
183 - 209 GeV with a total integrated luminosity of 680 inverse picobarns. Only
CP-conserving couplings are considered and SU(2)xU(1) relations between the WWZ
and the WWgamma couolings are used, resulting in four independent couplings.
Each coupling is determined in a separate fit, assuming the other couplings to
take their Standard Model values. Fits are also done allowing some of the
couplings to vary simultaneously. The results are compared with the Standard
Model predictions.


title: Measurement of D*+- production in deep inelastic ep scattering at HERA

abstract:
  Inclusive production of $D^*(2010)$ mesons in deep inelastic scattering has
been measured with the ZEUS detector at HERA using an integrated luminosity of
81.9 pb$^{-1}$. The decay channel $D^{* +}\to D^0 \pi^+ $ with $D^0\to
K^-\pi^+$ and corresponding antiparticle decay were used to identify $D^*$
mesons. Differential $D^*$ cross sections with $1.5<Q^2<1000$ GeV$^2$ and
$0.02<y<0.7$ in the kinematic region $1.5<p_T(D^*)<15$ GeV and
$|\eta(D^*)|<1.5$ are compared to different QCD calculations incorporating
different parameterisations of the parton densities in the proton. The data
show sensitivity to the gluon distribution in the proton and are reasonably
well described by next-to-leading-order QCD with the ZEUS NLO QCD fit used as
the input parton density in the proton. The observed cross section is
extrapolated to the full kinematic region in $p_T(D^*)$ and $\eta(D^*)$ in
order to determine the open-charm contribution, $F_2^{\rm charm}(x,Q^2)$, to
the proton structure function, $F_2$. Since, at low $Q^2$, the uncertainties of
the data are comparable to those from the QCD fit, the measured differential
cross sections in $y$ and $Q^2$ should be used in future fits to constrain the
gluon density.


title: B Decays at BABAR

abstract:
  We present branching fraction and CP asymmetry results for a variety of B
decays based on up to 56.4 fb^-1 collected by the BaBar experiment running near
the Upsilon(4S) resonance at the PEP-II e+e- B-factory.


title:
Search for Light Higgs Boson at LHC via Production Through Weak Boson
  Fusion

abstract:
  The LHC potential for observing a light Higgs boson produced through Weak
Boson Fusion mode, ${\rm qq}\to {\rm qqH}$, is presented. For non-hadronic
decays modes of the Higgs boson the process is identified with a final state
containing two energetic forward-backward jets, separated with a large rapidity
and a hadronically quiet central region. The use of these properties, combined
with special features of some of the decay modes enhances the potential of an
early discovery of a light Higgs boson both in the Standard Model and beyond.
The recent studies done in the context of CMS experiment are discussed.


title:
Improving ellipticity detection sensitivity for the Q & A vacuum
  birefringence experiment

abstract:
  Q & A (quantum electrodynamics test and search for axion) experiment was
first proposed in 1994 and a 3.5 m high-finesse Fabry-Perot prototype detector
extendable to 7 m has been built and tested. We now enter into the 2nd phase of
improving the ellipticity detection sensitivity. We present our scheme, compare
with other ongoing experiments, analyze the displacement spectra of our
suspension system, and use them for designing automatic alignment control to
improve the ellipticicy detection sensitivity. To improve ellipsometry
resolution, we use new polarizers of extinction ratio smaller than 10^{-8}.


title:
Measurement of the Angle $\phi_1(\beta)$ and $B \bar B$ Mixing (Recent
  Results from BaBar and Belle)

abstract:
  Recent results from BaBar and Belle experiments on $B \bar B$ mixing and
$\sin 2\phi_1$ are presented. Accuracy of $\Delta m_d$ measurements has reached
1.2%. Higher order effects within the Standard Model or possible new physics
effect that might appear in the $B \bar B$ mixing through non-zero $\Delta
\Gamma/\Gamma$, CP violation, or $CPT$ violation have been explored. The BaBar
and Belle results on $\sin 2\phi_1$ from the $b \to c \bar{c} s$ modes are in
good agreement with each other and a combined result with an accuracy of 8% is
in good agreement with a global CKM fit. A simple average of the $\sin 2\phi_1$
values that were measured in the penguin-loop dominated decay modes, $\phi
K_S$, $\eta^{\prime} K_S$, and $K^+ K^- K_S$, shows about 2.5$\sigma$ deviation
from the Standard Model.
