title: Search for $\beta^+$EC and ECEC processes in $^{74}$Se

abstract:
  For the first time, limits on double-beta processes in $^{74}$Se have been
obtained using a 400 cm$^3$ HPGe detector and an external source consisting of
natural selenium powder.
  At a confidence level of 90%, they are $1.9\times 10^{18}$ y for the
$\beta^+$EC$(0\nu + 2\nu)$ transition to the ground state, $7.7\times 10^{18}$
y for the ECEC($2\nu$) transition to the $2^+_1$ excited state in $^{74}$Ge
(595.8 keV), $1.1\times 10^{19}$ y for the ECEC($0\nu$) transition to the
$2^+_1$ excited state in $^{74}$Ge (595.8 keV) and $5.5\times 10^{18}$ y for
the ECEC($2\nu$) and ECEC($0\nu$) transitions to the $2^+_2$ excited state in
$^{74}$Ge (1204.2 keV). The last transition is discussed in association with a
possible enhancement of the decay rate, in this case by several orders of
magnitude, because the ECEC$(0\nu)$ process is nearly degenerate with an
excited state in the daughter nuclide. Prospects for investigating such
processes in future experiments are discussed.


title: Hadronic Charm Decays in CLEO

abstract:
  We present several results on hadronic D meson decays. We report on results
from the scan of the energy region from 3970 MeV to 4260 MeV, which was used to
determine an optimal energy to carry out the D_s physics program of CLEO-c.
Improved measurements of inclusive and exclusive D and D_s branching fractions
are presented. We also show results on Dalitz analyses of D^+-->pi^+pi^-pi^+
using CLEO-c data and D^0--> K^+K^-pi^0 using CLEO III data.


title: Cabibbo-Allowed and Doubly Cabibbo Suppressed D -->K pi Decays

abstract:
  We present measurements of the branching fractions of the decays,
D-->K^0_{S,L}pi. The measured asymmetry shows that B(D^0--> K^0_S pi^0) is not
equal to B(D^0--> K^0_L pi^0), as expected. We also find that B(D^+ --> K^0_S
pi^+) is statistically compatible with B(D^+ --> K^0_L pi^+). Lastly, we
present a recent measurement of the branching fraction of the doubly
Cabibbo-suppressed decay, D^+ --> K^+ pi^0.


title: Study of Charm Baryons with the BaBar Experiment

abstract:
  We report on several studies of charm baryon production and decays by the
BaBar collaboration. We confirm previous observations of the $\Xi_c^{'0/+}$,
$\Xi_c(2980)^+$ and $\Xi_c(3077)^+$ baryons, measure branching ratios for
Cabibbo-suppressed $\Lambda_c^+$ decays and use baryon decays to study the
properties of the light-quark baryons, $\Omega^-$ and $\Xi(1690)^0$.


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

abstract:
  The inclusive reaction $p A \to pK^0_s + X$ was studied at IHEP accelerator
with $70 GeV$ proton beam using SVD-2 detector. Two different samples of
$K^0_s$, statistically independent and belonging to different phase space
regions were used in the analyses and a narrow baryon resonance with the mass
$M=1523\pm 2(stat.)\pm 3(syst.) MeV/c^2$ was observed in both samples of the
data


title:
Exploring the Spin Structure of the Proton with Two-Body Partonic
  Scattering at RHIC

abstract:
  The STAR collaboration at the Relativistic Heavy Ion Collider is using
polarized proton beams at sqrt{s} = 200 GeV to study the spin structure of the
proton. The first results for the double spin helicity dependence of inclusive
jet production are presented along with projections for additional data taken
in 2005 and 2006. When fully analyzed these data sets should place strong
constraints on the possible contribution of gluonic spin to the proton spin as
expressed by Delta G. Future studies using 2-jet or photon-jet coincidences to
map out the gluon spin distribution vs. the gluon's momentum fraction of the
proton are discussed.


title:
Luminosity Measurement Method for LHC: The theoretical precision and the
  experimental challenges

abstract:
  This is the first of the series of papers which present a precision method of
the day-by-day monitoring of the absolute LHC luminosity. The method is based
on the measurement of the rate of coplanar lepton pairs produced in peripheral
collisions of the beams' particles. In the present paper we evaluate the
modeling precision of the lepton pair production processes in proton-proton
collisions, optimize the measurement region to achieve better than 1% accuracy
of the predicted rates, and discuss the experimental challenges to filter out
the luminosity monitoring lepton pairs at LHC.


title: W + Jet Production at CDF

abstract:
  The cross section for the inclusive production of W bosons in association
with jets in ppbar collisions at sqrt(s)=1.96 TeV using the Collider Detector
at Fermilab (CDF II) is presented. The measurement is based on an integrated
luminosity of 320pb^-1, and includes events with up to 4 or more jets. In each
jet multiplicity sample the differential and cumulative cross sections with
respect to the transverse energy of the i^th-jet are measured. For W+>=2 jets
the differential cross section with respect to the 2-leading jets invariant
mass m_j1j2 and angular separation Delta R_j1j2 is also reported. The data are
compared to predictions from Monte Carlo simulations.


title:
Measurement of exclusive $B \to X_u \ell \nu$ decays using a
  full-reconstruction tag at Belle

abstract:
  We report a preliminary study of the branching fractions and $q^2$
distributions of exclusive charmless semileptonic B decays, using events tagged
by fully reconstructing one of the $B$ mesons in a hadronic decay mode. These
results are obtained from a data sample that contains 535 $\times 10^6\
B\bar{B}$ pairs, collected near the $\Upsilon(4S)$ resonance with the Belle
detector at the KEKB asymmetric energy $e^+ e^-$ collider.


title: Search for Higgs at CDF

abstract:
  We present the results on the searches for the SM and the non-SM Higgs boson
production in ppbar collisions at sqrt(s)=1.96 TeV with the CDF detector at the
Fermilab Tevatron. Using data corresponding to 300--700pb-1, we search for the
Higgs boson in various production and decay channels. No signal is observed,
therefore, we set upper limits on the production cross-section times branching
fraction as a function of the Higgs boson mass.


title:
Search for Invisibly Decaying Higgs Bosons with Large Decay Width Using
  the OPAL Detector at LEP

abstract:
  This paper describes a topological search for an invisibly decaying Higgs
boson,H, produced via the Bjorken process (e+e- -> HZ). The analysis is based
on data recorded using the OPAL detector at LEP at centre-of-mass energies from
183 to 209 GeV corresponding to a total integrated luminosity of 629pb-1. In
the analysis only hadronic decays of the Z boson are considered. A scan over
Higgs boson masses from 1 to 120 GeV and decay widths from 1 to 3000 GeV
revealed no indication for a signal in the data. From a likelihood ratio of
expected signal and Standard Model background we determine upper limits on
cross-section times branching ratio to an invisible final state. For moderate
Higgs boson decay widths, these range from about 0.07pb Mh = 60GeV) to 0.57pb
(Mh = 114GeV). For decay widths above 200GeV the upper limits are of the order
of 0.15pb. The results can be interpreted in general scenarios predicting a
large invisible decay width of the Higgs boson. As an example we interpret the
results in the so-called stealthy Higgs scenario. The limits from this analysis
exclude a large part of the parameter range of this scenario experimentally
accessible at LEP2.


title:
Evidence of a Broad Structure at an Invariant Mass of 4.32 GeV/$c^2$ in
  the Reaction $e^+e^-\to\pi^+\pi^-\psi(2S)$ Measured at BaBar

abstract:
  We present a measurement of the cross section of the process
$e^+e^-\to\pi^+pi^-\psi(2S)$ from threshold up to 8 GeV center-of-mass energy
using events containing initial-state radiation, produced at the PEP-II
$e^+e^-$ storage rings. The study is based on 298 fb$^{-1}$ of data recorded
with the BaBar detector. A structure is observed in the cross-section not far
above threshold, near 4.32 GeV. We also investigate the compatibility of this
structure with the Y(4260) previously reported by this experiment.


title: Exotic Physics at HERA

abstract:
  A search for excited neutrinos, the analysis of multi-lepton final states, a
search for doubly charged Higgs production and a general search for high-Pt
phenomena at HERA are reported. The searches use data samples of ep collisions
with a centre-of-mass energy sqrt(s)=320 GeV collected by the H1 and ZEUS
experiments at HERA in the years 1994-2005 with integrated luminosities up to
296 pb^-1. Overall no significant deviations of the experimental observations
from the Standard Model (SM) expectation are found.


title: Status of |Vub|, |Vcb| and their relative phase

abstract:
  The current status of the determinations of the CKM elements Vub and Vcb is
reviewed and future prospects are discussed.


title: WW Production, Polarisation and Spin Correlations at LEP

abstract:
  Results on W-pair productions at LEP2 are reviewed and their consistency with
standard electroweak expectations is summarised. Special interest is given to
measurements of W polarisation, and to new studies of spin and decay-plane
correlations among the W pairs.


title: Low-x QCD physics from RHIC and HERA to the LHC

abstract:
  We present a summary of the physics of gluon saturation and non-linear QCD
evolution at small values of parton momentum fraction $x$ in the proton and
nucleus in the context of recent experimental results at HERA and RHIC. The
rich physics potential of low-x studies at the LHC, especially in the forward
region, is discussed and some benchmark measurements in pp, pA and AA
collisions are introduced.


title: Measurement of the ratio Br(D0 --> pi+pi-pi0)/Br(D0 --> K-pi+pi0)

abstract:
  We report a high-statistics measurement of the relative branching fraction
Br(D0 --> pi+pi-pi0)/Br(D0 --> K-pi+pi0). A 357 inverse fb data sample
collected with the Belle detector at the KEKB asymmetric-energy e+e- collider
was used for the analysis. The relative branching fraction Br(D0 -->
pi+pi-pi0)/Br(D0 --> K-pi+pi0) is determined with an accuracy comparable to the
latest world average value.


title: High precision study of K+- --> 3pi+- decays by NA48/2

abstract:
  Preliminary results of study of $K^\pm\to3\pi^\pm$ decays by the NA48/2
experiment at CERN SPS are presented. They include a precise measurement of the
direct CP violating charge asymmetry of Dalitz plot linear slope parameters
$A_g=(g^+-g^-)/(g^++g^-)$, and a measurement of the Dalitz plot slope
parameters $(g,h,k)$ themselves. Due to the design of the experiment, and a
large data set collected, unprecedented precisions were achieved.


title: The E6 inspired isosinglet quark and the Higgs boson

abstract:
  We consider the experimental implications of the down type isosinglet quark,
$D$, predicted by the $E_{6}$, group to Higgs boson searches at the LHC. The
pair production of $D$ quarks at the LHC and their subsequent decays $D\to h d$
and $D\to W u$ has been analyzed. For a light Higgs boson of mass O(120 GeV),
an analysis based on fast simulation of the ATLAS detector response shows that,
the $b\bar{b}$ channel becomes as efficient as the $\gamma\gamma$ channel for
discovering the Higgs particle if $m_{D}<630$ GeV.


title: Improved measurement of $B^0 \to \pi^0 \pi^0$

abstract:
  We report an improved measurement of the decay $B^0 \to \pi^0 \pi^0$, using a
data sample of 535 $\times 10^6 B\bar{B}$ pairs collected at the $\Upsilon(4S)$
resonance with the Belle detector at the KEKB asymmetric energy $e^+ e^-$
collider. The measured branching fraction is ${\cal B}(B^0 \to \pi^0 \pi^0) =
1.1\pm 0.3(stat.) \pm 0.1(syst.)$, with a significance of 5.4 standard
deviations including systematic uncertainties.
  We also report the partial rate asymmetry: $\acp(B^0 \to \pi^0 \pi^0)$ = 0.44
$^{+0.73}_{-0.62}$(stat.)$^{+0.04}_{-0.06}$(syst.).


title: New NA48 Results on Kaon and Hyperon Decays

abstract:
  The NA48 Collaboration has obtained several new results on kaon and neutral
hyperon decays. For hyperons we present new, very precise measurements on the
Xi0 lifetime and the decay asymmetries of Xi0 -> Lamda gamma and Xi0 -> Sigma0
gamma. On kaon decays, we report on the first observation of the interference
term between Inner Bremsstrahlung and Direct Emission in K+- -> pi+- pi0 gamma
and on a new, accurate measurement of the form factor slopes in the
semileptonic decay KL -> pi+- mu-+ nu.


title:
Search for Lepton Flavor Violating Decays $\tau^\pm \to \ell^\pm{\pi^0},
  \ell^\pm\eta, \ell^\pm{\eta^\prime}$

abstract:
  A search for lepton flavor violating decays of the $\tau$ lepton to a lighter
mass lepton and a pseudoscalar meson has been performed using 339 fb$^{-1}$ of
$e^+e^-$ annihilation data collected at a center-of-mass energy near 10.58 GeV
by the BaBar detector at the SLAC PEP-II storage ring. No evidence of signal
has been found, and upper limits on the branching fractions are set at
$10^{-7}$ level.


title:
A new measurement of the Collins and Sivers asymmetries on a
  transversely polarised deuteron target

abstract:
  New high precision measurements of the Collins and Sivers asymmetries of
charged hadrons produced in deep-inelastic scattering of muons on a
transversely polarised 6LiD target are presented. The data were taken in 2003
and 2004 with the COMPASS spectrometer using the muon beam of the CERN SPS at
160 GeV/c. Both the Collins and Sivers asymmetries turn out to be compatible
with zero, within the present statistical errors, which are more than a factor
of 2 smaller than those of the published COMPASS results from the 2002 data.
The final results from the 2002, 2003 and 2004 runs are compared with naive
expectations and with existing model calculations.


title: A High Intensity Linear e+ e- Collider Facility at Low Energy

abstract:
  I discuss a proposal for a high intensity $e^+e^-$ linear collider operated
at low center of mass energies $\sqrt{s}<5$ GeV with high intensity beams. Such
a facility would provide high statistics samples of (charmed) vector mesons and
would permit searches for LFV with unprecedented precision in decays of $\tau$
leptons and mesons. Implications on the design of the linear accelerator are
discussed together with requirements to achieve luminosities of $10^{35}$
cm$^{-2}$s$^{-1}$ or more.


title: Vus Measurement and CKM unitarity

abstract:
  We review recent measurements of kaon decays and lifetimes for the
determination of the CKM element Vus. Their relevance to CKM matrix unitarity
is discussed.


title: Measurements of Ke4 and K+- -> pi0 pi0 pi+- decays

abstract:
  The NA48/2 experiment at the CERN SPS collected in 2003 and 2004 large
samples of the decays K+- -> pi+ pi- e+- nu (Ke4+-), K+- -> pi0 pi0 e+- nu
(Ke400) and K+- -> pi0 pi0 pi+-. From the Ke4+- form factors and from the cusp
in the M00^2 distribution of the K+- -> pi0 pi0 pi+- events, the pi-pi
scattering lengths a00 and a20 could be extracted. This measurement is a
fundamental test of Chiral Perturbation Theory (ChPT). The branching fraction
and form factors of the Ke400 decay were precisely measured, using a much
larger data sample than in previous experiments.


title: Measurement of the rare decay pi0 -> e+ e-

abstract:
  The branching ratio of the rare decay pi0 -> e+ e- has been measured
precisely, using the complete data set from the KTeV E799-II experiment at
Fermilab. We observe 794 candidate pi0 -> e+ e- events using K0_L -> 3pi0 as a
source of tagged pi0's. The expected background is 52.7 +- 11.2 events,
predominantly from high e+ e- mass pi0 -> e+ e- gamma decays. We have measured
B[(pi0 -> e+ e-), (m_e+e-/m_pi0)^2 > 0.95] = 6.44 +- 0.25(stat) +- 0.22(syst)
x10^(-8), which is above the unitary bound from pi0 -> gamma gamma and within
the range of theoretical expectations from the standard model.


title: Vector-Tensor and Vector-Vector Decay Amplitude Analysis of B0->phi K*0

abstract:
  We perform an amplitude analysis of the decays B0->phi K^*_2(1430)0, phi
K^*(892)0, and phi(K pi)^0_S-wave with a sample of about 384 million BBbar
pairs recorded with the BABAR detector. The fractions of longitudinal
polarization f_L of the vector-tensor and vector-vector decay modes are
measured to be 0.853 +0.061-0.069 +-0.036 and 0.506 +-0.040 +-0.015,
respectively. Overall, twelve parameters are measured for the vector-vector
decay and seven parameters for the vector-tensor decay, including the branching
fractions and parameters sensitive to CP-violation.


title: Search for Single-Top-Quark Production at the Tevatron

abstract:
  This article reports on recent searches for single-top-quark production by
the CDF and DO collaborations at the Tevatron. Neither two CDF analyses, using
data corresponding to 695 pb^-1 of integrated luminosity, nor a DO search based
on 370 pb^-1 of data can establish a signal for this standard model process.
These null results translate in upper limits on the cross section of 2.9 pb for
the t-channel production mode and 3.2 pb for the s-channel mode at the 95% C.L.
In addition, the DO collaboration has searched for non-standard model
production of single-top-quarks via a heavy W^prime boson. No signal of this
process is found resulting in lower mass limits of 610 GeV/c^2 for a
left-handed W^prime and 630 GeV/c^2 for a right-handed W^\prime boson.


title: Studies of Fragmentation and Colour Reconnection at LEP

abstract:
  Hadronic events at the Z pole have been investigated in search for Colour
Reconnection effects and QCD coherence. Colour Reconnection effects are
searched for in three-jet events and the data results are compared to the
predictions of different Monte Carlo models. QCD colour coherence effects are
tested through the multiplicity distributions of hadrons with restricted
momenta, and the LEP1 e+e- data is compared to HERA e+p data under the
equivalence assumption of the e+e- hemisphere with the current region of the
Breit frame of reference.


title:
Diffractive Open Charm Production in Deep-Inelastic Scattering and
  Photoproduction at HERA

abstract:
  Measurements are presented of diffractive open charm production at HERA. The
event topology is given by ep -> eX Y where the system X contains at least one
charmed hadron and is well separated by a large rapidity gap from a leading
low-mass proton remnant system Y. Two analysis techniques are used for the
cross section measurements. In the first, the charm quark is tagged by the
reconstruction of a D*(2010) meson. This technique is used in deep-inelastic
scattering (DIS) and photoproduction. In the second, a method based on the
displacement of tracks from the primary vertex is used to measure the open
charm contribution to the inclusive diffractive cross section in DIS. The
measurements are compared with next-to-leading order QCD predictions based on
diffractive parton density functions previously obtained from a QCD analysis of
the inclusive diffractive cross section at H1. A good agreement is observed in
the full kinematic regime, which supports the validity of QCD factorization for
open charm production in diffractive DIS and photoproduction.


title:
A New Measurement of Exclusive \boldmath$\rho^{\circ}$ Photoproduction
  at HERA

abstract:
  Exclusive $\rho^{\circ}$ photoproduction has been measured with high
statistics by the H1 Collaboration. The kinematical range is $20 < W < 90$ GeV,
$|t|<3$ GeV$^2$ and $Q^2<4$ GeV$^2$. Cross sections are measured differentially
in $W$ and $t$ and allow the extraction of the Pomeron trajectory, for the
first time using $\rho^{\circ}$ photoproduction data of one single experiment.
The preliminary result,
  $\alpha_{\mathbb{P}} (t) = 1.093 \pm 0.003 (stat.) ^{+0.008}_{-0.007} (syst.)
+ (0.116 \pm 0.027 (stat.) ^{+0.036}_{-0.046} (syst.)$ GeV$^{-2} \cdot t$,
deviates significantly from the canonical expectation.


title: KTeV Results on Chiral Perturbation Theory

abstract:
  The KTeV experiment has carried out a broad program of studies of rare kaon
decays. In this paper we present results on KL -> pi0 gamma gamma, KL -> pi0 e+
e- gamma and KL -> pi0 pi0 gamma. These decays provide a window for testing
chiral perturbation theory at O(p^6). We find BR(KL-> pi0 pi0 gamma) = (1.30
+/- 0.03 +/- 0.04)E-6, BR(KL-> pi0 e+ e- gamma) = (1.90 +/- 0.16 +/- 0.12)E-8,
and set the limit BR(KL->pi0 pi0 gamma)< 2.32E-7. The KTeV measurements are
competitive with or better than the world's best results in these decays.


title: Measurements of psi(2S) decays to octet baryon-antibaryon pairs

abstract:
  With a sample of 14 million psi(2S) events collected by the BESII detector at
the Beijing Electron Positron Collider (BEPC), the decay channels psi(2S)->p
p-bar, Lambda Lambda-bar, Sigma0 Sigma0-bar, Xi Xi-bar are measured, and their
branching ratios are determined to be (3.36+-0.09+-0.24)*10E-4,
(3.39+-0.20+-0.32)*10E-4, (2.35+-0.36+-0.32)*10E-4, (3.03+-0.40+-0.32)*10E-4,
respectively. In the decay psi(2S)->p p-bar, the angular distribution parameter
alpha is determined to be 0.82+-0.17+-0.04.


title:
Latest Results on Orbitally Excited Strange Bottom Mesons with the CDF
  II Detector

abstract:
  We present the latest results on the spectroscopy of orbitally excited
strange bottom mesons from 1 fb^{-1} of CDF data. The measurements are
performed with fully reconstructed B- decays collected by the CDF II detector
at the sqrt(s)-energy of 1.96 TeV in both the di-muon and the fully hadronic
trigger paths.


title: Dalitz Analysis of Three-body Charmless B0=>K0pi+pi- Decay

abstract:
  We report results of a Dalitz plot analysis of the three-body charmless
B0=>K0pi+pi- decay. The analysis is performed with a data sample that contains
388 million BBbar pairs collected near the Y(4S) resonance with the Belle
detector at the KEKB asymmetric energy e+e- collider. Measurements of branching
fractions for the quasi-two-body decays B0=>rho(770)0K0, B0=>f0(980)K0,
B0=>K*(892)+pi-, B0=>K*(1430)+pi-, and upper limits on several other
quasi-two-body decay modes are reported.


title: Electroweak physics at HERA

abstract:
  The HERA experiments have collected interesting luminosity samples with both
polarized and unpolarized lepton beams. The polarized CC data are directly
sensitive to right handed charged currents. The data are in agreement with the
SM predicting their absence. Effects of Z-exchange have been seen in the lepton
beam charge and polarization assymetries. A combined electroweak and QCD
analysis allows one to measure electroweak parameters with world competitive
accuracy.


title: SUSY Higgs Searches at DZERO, Tevatron

abstract:
  During Run II of the Tevatron collider, D\O collaboration has made extensive
searches for the neutral MSSM Higgs bosons ($\phi$), produced in $\rm p\bar{p}$
collisions at $\rm \sqrt{s}=1.96$ TeV. Two such analyses, addressing inclusive
$\phi$ production with $\phi\to\tau^+\tau^-$, and associated $\phi b(\bar{b})$
production with $\phi\to b\bar{b}$ are reported here. No excess of events above
the background expectation has been observed in any of these analyses. The
results are combined to set constraints on the MSSM parameter space.


title: Search for B+ -> J/psi eta' K+ and B0 -> J/psi eta' Ks0 Decays

abstract:
  We report the results of searches for B+ -> J/psi eta' K+ and B0 -> J/psi
eta' Ks0 decays, using a sample of 388 x 10^6 BBbar pairs collected with the
Belle detector at the Upsilon(4S) resonance. No statistically significant
signal is found for either of the two decay modes and upper limits for the
branching fractions are determined to be B(B+ -> J/psi eta' K+) < 8.8 x 10^-5
and B(B0 -> J/psi eta' Ks0) < 2.5 x 10^-5 at 90% confidence level.


title:
Barionic Resonances with Positive Strangeness S=+1 in the System nK+
  from the Reaction np -> npK+K- at the Momentum of Incident Neutrons Pn=5.20
  Gev/c

abstract:
  The production and properties of the resonances with the strangeness S=+1 in
the system of nK+ were studied in the reaction np->npK+K- at the momentum of
incident neutrons Pn=(5.20 +/- 0.12)GeV/c. A number of peculiarities were found
in the effective mass spectrum of the mentioned above system. Their widths are
comparable with the mass resolution. The estimation of the spins of resonances
was carried out and the rotational band connecting the resonances masses and
their spins was constructed.

Strange Multibaryon States with \Lambda Hyperon Systems in pa Collision
  at 10 Gev/c

abstract:
  Experimental data from the 2m propane bubble chamber have been analyzed for
exotic baryon states search. A number of peculiarities were found in the
effective mass spectra of: $\Lambda \pi^+$($\Sigma^{*+}$(1382),PDG), $\Lambda
p$ and $\Lambda p p$ subsystems. A few events detected on the photographs of
the propane bubble chamber exposed to a 10 GeV/c proton beam, were interpreted
as S=-2 $H^0$ light($<M_{(\Lambda \Lambda)}$) and heavy $H^{0,+}$. New event,
detected on the photographs of the propane bubble chamber was interpreted as
heavy $H^+(2488)$ dibaryon by weak decay channels of $K^-pp$ or $ \Sigma^+
p\pi^-$.


title: Search for Physics beyond the Standard Model at the Tevatron

abstract:
  Recent searches for physics beyond the standard model at the Tevatron are
reported, with emphasis on supersymmetry.


title:
Results of beyond the Standard Model Higgs searches from the LEP
  experiments

abstract:
  Since no Standard Model Higgs boson was discovered at LEP the searches were
extended to beyond the Standard Model Higgs scenarios. A selection of final
results from searches carried out by the four LEP experiments ALEPH, DELPHI, L3
and OPAL are presented that include data taken at the highest centre-of-mass
energies.


title: Universality and Lepton Flavor Violation in Upsilon Decays at CLEO

abstract:
  I present two analyses done with the CLEOIII detector at CESR. The first is a
search for the Lepton Flavor Violating decay Upsilon to mu tau, with
preliminary results, and the second constrains Lepton Universality in Upsilon
to tau tau relative to Upsilon to mu mu. This second analysis, whose results
are final, has dramatically improved uncertainties relative to other such
measurements, and is also the first observation of the decay Upsilon(3S) to tau
tau. A limit is also set on the involvement of a CP odd Higgs in the decay of
the Upsilon(1S) to tau pairs.


title: Search for Low Mass Higgs at the Tevatron

abstract:
  We present CDF and D0 searches for a Standard Model Higgs boson produced
associatively with a W or Z boson at sqrt{s}=1.96 TeV using up to 1 fb^-1 of
analyzed Tevatron data collected from February 2002 to February 2006. For Higgs
masses less than 135 GeV/c^2, as is favored by experimental and theoretical
constraints, WH->lnubb, ZH->llbb, and ZH->nunubb are the most sensitive decay
channels to search for the Higgs boson. Both CDF and D0 have analyzed these
three channels and found no evidence for Higgs production, and therefore set
upper limits on the Higgs production cross-section. While the analyses are not
yet sensitive to Standard Model Higgs production, improvements in analysis
techniques are increasing sensitivity to the Higgs much faster than added
luminosity alone.


title:
Measurement of the ttbar production cross section in pbarp collisions at
  sqrt(s) = 1.96 TeV using secondary vertex b tagging

abstract:
  We report a new measurement of the ttbar production cross section in pbarp
collisions at a center-of-mass energy of 1.96 TeV using events with one charged
lepton (electron or muon), missing transverse energy, and jets. Using 425
pb^{-1} of data collected using the D0 detector at the Fermilab Tevatron
Collider, and enhancing the ttbar content of the sample by tagging b jets with
a secondary vertex tagging algorithm, the ttbar production cross section is
measured to be: 6.6 \pm 0.9 (stat+syst) \pm 0.4 (lum) pb. This cross section is
the most precise D0 measurement to date for ttbar production and is in good
agreement with standard model expectations.


title:
Search for the pair production of scalar top quarks in the acoplanar
  charm jet topology in p pbar collisions at sqrt(s)=1.96 TeV

abstract:
  A search for the pair production of scalar top quarks, or stops, has been
performed in 360 pb-1 of data from p pbar collisions at a center-of-mass energy
of 1.96 TeV, collected by the D0 detector at the Fermilab Tevatron collider.
The stop decay mode considered is stop into c chi, where chi is the lightest
supersymmetric particle. The topology analyzed therefore consists of a pair of
acoplanar heavy-flavor jets with missing transverse energy. The data and
standard model expectation are in agreement, and a 95% C.L. exclusion domain in
the stop and chi mass plane has been determined, extending the domain excluded
by previous experiments.


title: New Results on X(3872) from CDF

abstract:
  In 2003 the X(3872) particle was discovered by the Belle collaboration.
Despite results collected since then, the nature of the state still remains
unclear. In this contribution we report on new results on properties of the
X(3872) state using data collected with CDF II detector at the Fermilab
Tevatron. The dipion mass spectrum and angular distributions are used to
determine the $J^{PC}$ quantum numbers of the state.


title: Probing Extra Dimensions with ATLAS

abstract:
  In the late nineties several authors suggested that the extra dimensions
predicted by string theory might lead to observable effects at high energy
colliders. The ATLAS experiment which will start taking data at the LHC in 2007
will be an excellent place to search for such effects. The sensitivity of ATLAS
to signatures of Extra Dimensions will be presented.


title: Search for Excited and Exotic Muons at CDF

abstract:
  We present a search for the production of excited or exotic muons (mu*) via
the reaction pbar + p -> mu* + mu -> mu gamma + mu using 371/pb of data
collected with the Run II CDF detector. In this signature-based search, we look
for a resonance in the mu-gamma mass spectrum. The data are compared to
standard model and detector background expectations, and with predictions of
excited muon production. We use these comparisons to set limits on the mu* mass
and compositeness scale Lambda in the contact interaction and gauge-mediated
models.


title: Charm spectroscopy and exotics at ZEUS

abstract:
  Light and charmed hadrons are produced copiously in ep collisions with a
centre-of-mass energy of 318 GeV at HERA. Results of the ZEUS Collaboration on
pentaquark searches, deuteron and antideuteron production and charmed-meson
spectroscopy, obtained using the HERA I data, are summarised.


title: Observations of the Askaryan Effect in Ice

abstract:
  We report on the first observations of the Askaryan effect in ice: coherent
impulsive radio Cherenkov radiation from the charge asymmetry in an
electromagnetic (EM) shower. Such radiation has been observed in silica sand
and rock salt, but this is the first direct observation from an EM shower in
ice. These measurements are important since the majority of experiments to date
that rely on the effect for ultra-high energy neutrino detection are being
performed using ice as the target medium. As part of the complete validation
process for the Antarctic Impulsive Transient Antenna (ANITA) experiment, we
performed an experiment at the Stanford Linear Accelerator Center (SLAC) in
June 2006 using a 7.5 metric ton ice target, yielding results fully consistent
with theoretical expectations.


title: Some Searches for New Physics with the D0 Detector

abstract:
  We present recent results on Technicolor and Leptoquark searches obtained
analyzing up to 0.4 fb-1 of data taken at Fermilab by the D0 experiment during
the firs part of the Tevatron Run II.


title:
Searches for Gauge-Mediated SUSY Breaking Topologies with the L3
  Detector at LEP

abstract:
  Searches for topologies predicted by gauge-mediated SUSY breaking models were
performed using data collected with the L3 detector at LEP. All possible
lifetimes of the next-to-lightest SUSY particle (NLSP), neutralino or scalar
tau, were considered. No evidence for these new phenomena was found and limits
on the production cross sections and sparticle masses were derived. A scan over
the parameters of the minimal GMSB model was performed, leading to lower limits
of 62.2 GeV, 11 TeV, and 0.07 eV on the NLSP mass, the mass scale parameter
Lambda, and the gravitino mass, respectively. The status of the LEP combined
searches is also discussed.


title:
Searches for Gauge-Mediated Supersymmetry Breaking Topologies in e+e-
  collisions at LEP2

abstract:
  In gauge-mediated supersymmetry (SUSY) breaking (GMSB) models the lightest
supersymmetric particle (LSP) is the gravitino and the phenomenology is driven
by the nature of the next-to-lightest SUSY particle (NLSP) which is either the
lightest neutralino, the stau or mass degenerate sleptons. Since the NLSP decay
length is effectively unconstrained, searches for all possible lifetime and
NLSP topologies predicted by GMSB models in e+e- collisions are performed on
the data sample collected by OPAL at centre-of-mass energies up to 209 GeV at
LEP. Results independent of the NLSP lifetime are presented for all relevant
final states including direct NLSP pair-production and, for the first time,
also NLSP production via cascade decays of heavier SUSY particles. None of the
searches shows evidence for SUSY particle production. Cross-section limits are
presented at the 95% confidence level both for direct NLSP production and for
cascade decays, providing the most general, almost model independent results.
These results are then interpreted in the framework of the minimal GMSB (mGMSB)
model, where large areas of the accessible parameter space are excluded. In the
mGMSB model, the NLSP masses are constrained to be larger than 53.5 GeV/c^2,
87.4 GeV/c^2 and 91.9 GeV/c^2 in the neutralino, stau and slepton co-NLSP
scenarios, respectively. A complete scan on the parameters of the mGMSB model
is performed, constraining the universal SUSY mass scale Lambda from the direct
SUSY particle searches: Lambda > 40, 27, 21, 17, 15 TeV/c^2 for messenger
indices N=1, 2, 3, 4, 5 respectively, for all NLSP lifetimes.


title: Stop production in R-parity violating supersymmetry at Tevatron

abstract:
  Costraints for stop production in R-parity violating supersymmetry at
Tevatron have been evaluated using the D0 limits for first generation
leptoquarks. Such limits have been converted in constraints for the lambda'_131
R-parity violating coupling as a function of the stop mass for different
Minimal Supersymmetric Standatd Model (MSSM) scenarios and compared with Atomic
Parity Violation and HERA results. The D0 limits have also been interpreted in
terms of constraints on the parameters of the minimal Supergravity model. For a
part of the considered MSSM parameter space and for stop mass less than 240
GeV, Tevatron results are the best to date.


title:
chi_c0 and chi_c2 Decays into eta eta, eta eta', and eta' eta' Final
  States

abstract:
  Using a sample of 3 x 10^6 psi(2S) decays collected by the CLEO III and
CLEO_c detector configurations, we present results of a study of \chi_{c0} and
\chi_{c2} decays into eta-eta, eta-etaprime, and etaprime-etaprime final
states. We find B(chi_{c0} -> eta-eta)= (0.31+-0.05+-0.04+-0.02)%, B(chi_{c0}
-> eta-etaprime) <0.05 % at the 90% confidence level, and B(chi_{c0} ->
etaprime-etaprime) = (0.17 +- 0.04 +-0.02 +-0.01)%. We also present upper
limits for the decays of \chi_{c2} into these final states. These results give
information on the decay mechanism of \chi_c states into pseudoscalars.


title: Review of Recent Measurements of the Sides of the CKM Unitarity Triangle

abstract:
  We give a review of the status of the global effort to measure the sides of
the CKM Unitarity Triangle.


title: Mechanism of the close-to-threshold production of the eta meson

abstract:
  Measurements of the analysing power for the p(pol)p --> ppeta reaction have
been performed in the close-to-threshold energy region at beam momenta of
p_{beam}=2.010 and 2.085 GeV/c, corresponding to excess energies of Q=10 and 36
MeV, respectively. The determined analysing power is essentially consistent
with zero implying that the eta meson is produced predominantly in the s-wave
at both excess energies. The angular dependence of the analysing power,
combined with the hitherto determined isospin dependence of the total cross
section for the eta meson production in nucleon-nucleon collisions, reveal a
statistically significant indication that the excitation of the nucleon to the
S_{11}(1535) resonance, the process which intermediates the production of the
eta meson, is predominantly due to the exchange of the pi meson between the
colliding nucleons.


title:
Parametrization of Bose-Einstein Correlations and Reconstruction of the
  Source Function in Hadronic Z-boson Decays using the L3 Detector

abstract:
  Bose-Einstein correlations of pairs of identical charged pions produced in
hadronic Z decays are analyzed in terms of various parametrizations. A good
description is achieved using a Levy stable distribution in conjunction with a
hadronization model having highly correlated configuration and momentum space,
the tau-model. Using these results, the source function is reconstructed.


title: Measurements of top quark properties at CDF

abstract:
  The top quark with its mass of about 172 GeV/c^2 is the most massive
fundamental particle observed by experiment. In this talk we highlight the most
recent measurements of several top quark properties performed with the CDF
detector based on data samples corresponding to integrated luminosities up to 1
fb-1. These results include a search for top quark pair production via new
massive resonances, measurements of the helicity of the W boson from top-quark
decay, and a direct limit on the lifetime of the top quark.


title: Search for stop production in R-parity-violating supersymmetry at HERA

abstract:
  A search for stop production in R-parity-violating supersymmetry has been
performed in $e^{+}p$ interactions with the ZEUS detector at HERA, using an
integrated luminosity of 65 pb$^{-1}$. At HERA, the R-parity-violating coupling
$\lambda'$ allows resonant squark production, $e^+d\to\tilde{q}$. Since the
lowest-mass squark state in most supersymmetry models is the light stop,
$\tilde{t}$, this search concentrated on production of $\tilde{t}$, followed
either by a direct R-parity-violating decay, or by the gauge decay to
$b\tilde{\chi}^+_{1}$. No evidence for stop production was found and limits
were set on $\lambda'_{131}$ as a function of the stop mass in the framework of
the Minimal Supersymmetric Standard Model. The results have also been
interpreted in terms of constraints on the parameters of the minimal
Supergravity model.


title:
A search for the decay of the positive B meson into a positive tau
  lepton and a tau neutrino at the BaBar experiment

abstract:
  We present a search for the decay B+ -> tau+ nu using 288 inverse femtobarns
of data collected at the Upsilon(4S) resonance with the BaBar detector at the
SLAC PEP-II B-Factory. A sample of events with one reconstructed semileptonic B
decay (B- -> D0 l- nu X) is selected, and in the recoil a search for the signal
decay mode is performed. The tau is identified in four channels. We measure a
branching fraction of BF(B+ -> tau+ nu) = (0.88+0.68 -0.67(stat.) +-
0.11(syst.)) x 10^{-4} and extract an upper limit on the branching fraction, at
the 90% confdence level, of 1.8 x 10^{-4}.


title:
J/psi Production vs Transverse Momentum and Rapidity in p+p Collisions
  at sqrt(s) = 200 GeV

abstract:
  J/Psi production in p+p collisions at sqrt(s) = 200 GeV has been Measured in
the PHENIX experiment at the Relativistic Heavy Ion Collider (RHIC) over a
rapidity range of -2.2 < y < 2.2 and a transverse momentum range of 0 < pT < 9
GeV/c. The statistics available allow a detailed measurement of both the pT and
rapidity distributions and are sufficient to constrain production models. The
total cross section times branching ratio determined for J/Psi production is
B_{ll} sigma_pp^J/psi = 178 +/- 3(stat) +/- 53(syst) +/- 18(norm) nb.


title: Confirmation of the Y(4260) Resonance Production in ISR

abstract:
  Using 13.3 fb^-1 of e+e- collision data taken in the Upsilon(1S-4S) region
with the CLEO III detector at the CESR collider, a search has been made for the
new resonance Y(4260) recently reported by the BaBar Collaboration. The
production of Y(4260) in initial state radiation (ISR), and its decay into
pi+pi-J/psi are confirmed. A good quality fit to our data is obtained with a
single resonance. We determine M(Y(4260))=(4284+17-16(stat)+-4(syst)) MeV/c^2,
Gamma(Y(4260))=(73+39-25(stat)+-5(syst)) MeV/c^2, and
Gamma_ee(Y(4260))xBr(Y(4260)->pi+pi-J/psi)=(8.9+3.9-3.1(stat)+-1.9(syst))
eV/c^2.


title:
Search for Wprime Boson Decaying to Electron-Neutrino Pairs in pbarp
  Collisions at sqrt{s}=1.96 TeV

abstract:
  We present the results of a search for Wprime boson decaying to
electron-neutrino pairs in pbarp collisions at a center-of-mass energy of 1.96
TeV, using a data sample corresponding to 205 pb^-1 of integrated luminosity
collected by the CDF II detector at Fermilab. We observe no evidence for this
decay mode and set limits on the production cross section times branching
fraction, assuming the neutrinos from Wprime boson decays to be light. If we
assume the manifest left-right symmetric model, we exclude a Wprime boson with
mass less than 788 GeV/c^2 at the 95% confidence level.


title:
First events from the CNGS neutrino beam detected in the OPERA
  experiment

abstract:
  The OPERA neutrino detector at the underground Gran Sasso Laboratory (LNGS)
was designed to perform the first detection of neutrino oscillations in
appearance mode, through the study of nu_mu to nu_tau oscillations. The
apparatus consists of a lead/emulsion-film target complemented by electronic
detectors. It is placed in the high-energy, long-baseline CERN to LNGS beam
(CNGS) 730 km away from the neutrino source. In August 2006 a first run with
CNGS neutrinos was successfully conducted. A first sample of neutrino events
was collected, statistically consistent with the integrated beam intensity.
After a brief description of the beam and of the various sub-detectors, we
report on the achievement of this milestone, presenting the first data and some
analysis results.


title: The Radiative Return: A Review of Experimental Results

abstract:
  The radiative return is a new method for hadronic cross section measurements
at electron-positron colliders, which are operated at a fixed center-of-mass
energy. In order to lower the effective hadronic mass M_hadr only such events
are taken, in which one of the electrons or positrons has emitted an initial
state radiation photon. We present precision measurements of the pion form
factor from the Frascati phi-factory DAPHNE with the KLOE experiment and
measurements of higher particle multiplicities as well as a measurement of the
timelike proton-antiproton form factor from the BaBar experiment at the
B-factory PEP-II. These radiative return measurements are compared to results,
which are obtained by means of an energy scan, i.e. by means of a systematic
variation of the beam energy of the collider. We also report on the impact of
these measurements on the hadronic contribution of the anomalous magnetic
moment of the muon, which is obtained via a dispersion integral using hadronic
cross section data as input.


title: Why do we need the new BNL muon g-2 experiment now?

abstract:
  New final results from the CMD-2 and SND e+e- annihilation experiments,
together with radiative return measurements from BaBar, lead to recent
improvements in the standard model prediction for the muon anomaly. The
uncertainty at 0.48 ppm--a largely data-driven result--is now slightly below
the experimental uncertainty of 0.54 ppm. The difference, a_mu(expt)- a_mu(SM)
= (27.6 +/- 8.4) x 10^-10, represents a 3.3 standard deviation effect. At this
level, it is one of the most compelling indicators of physics beyond the
standard model and, at the very least, a major constraint for speculative new
theories such as SUSY or extra dimensions. Others at this Workshop detailed
further planned standard model theory improvements to a_mu. Here I outline how
BNL E969 will achieve a factor of 2 or more reduction in the experimental
uncertainty. The new experiment is based on a proven technique and track
record. I argue that this work must be started now to have maximal impact on
the interpretation of the new physics anticipated to be unearthed at the LHC.


title: Observation of the decay Upsilon(4S) -> Upsilon(1S) pi+ pi-

abstract:
  We study transitions between Upsilon states with the emission of charged
pions using 477 fb^{-1} of data collected with the Belle detector at the KEKB
asymmetric-energy e+ e- collider. We select inclusive Upsilon(4S) -> mu+ mu-
pi+ pi- X events (where X represents anything) and observe a peak in the
distribution of the mass difference Delta M = (M(mu+mu-pi+pi-) -M(mu+mu-)).
This peak, at Delta M = (1119.2 +/- 0.4) MeV/c^2, is identified as a signal for
the decay Upsilon(4S) -> Upsilon(1S) pi+ pi- with a subsequent transition
Upsilon(1S) -> mu+ mu-. The measured product branching fraction BR(Upsilon(4S)
-> Upsilon(1S) pi+ pi-) x BR(Upsilon(1S) -> mu+mu-)=(4.4 +/- 0.8(stat.) +/-
0.6(sys.)) x 10^{-6}. When the PDG value for BR(Upsilon(1S) -> mu+mu-) is used,
this corresponds to BR(Upsilon(4S) -> Upsilon(1S) pi+ pi-) = (1.8 +/-
0.3(stat.) +/- 0.2(sys.)) x 10^{-4} and a partial decay width Gamma(Upsilon(4S)
-> Upsilon(1S) pi+ pi-)=(3.7 +/- 0.6(stat.) +/- 0.7(sys.)) keV.


title: Search for psi(2S)--> eta_c pi^+ pi^- pi^0

abstract:
  Using 5.63 pb^-1 of data accumulated at the psi(2S) resonance with the CLEO
III and CLEO-c detectors corresponding to 3.08 million psi(2S) decays, a search
is performed for the decay psi(2S) -> eta_c pi^+pi^-pi^0 to test a theoretical
prediction based upon the assumption that the c \bar c pair in the psi(2S) does
not annihilate directly into three gluons but rather survives before
annihilating. No signal is observed, and a combined upper limit from six eta_c
decay modes is determined to be B(psi(2S) -> eta_c pi^+pi^-pi^0) < 1.0 x 10^-3
at 90% C.L. This upper limit is about an order of magnitude below the
theoretical expectation.


title:
Observation of the Exclusive Reaction e+e- -> phi eta at sqrt{s}=10.58
  GeV

abstract:
  We report the observation of $\e^+e^-\to \phi\eta$ near $\sqrt{s}$ = 10.58
GeV with 6.5 $\sigma$ significance in the $K^+K^-\gamma\gamma$ final state in a
data sample of 224 $fb^{-1}$ collected by the BaBar experiment at the PEP-II
$e^+e^-$ storage rings. We measure the restricted radiation-corrected cross
section to be $\sigma(\e^+e^- \to \phi \eta) =$$2.1\pm 0.4 (\mathrm{stat})\pm
0.1(\mathrm{syst}) \mathrm{fb}$ within the range $|\cos\theta^*| < 0.8$, where
$\theta^*$ is the center-of-mass polar angle of the $\phi$ meson. The $\phi$
meson is required to be in the invariant mass range of 1.008 $< m_{\phi} <$
1.035 \gevcc. The radiation-corrected cross section in the full $\cos\theta^*$
range is extrapolated to be $2.9\pm 0.5 (\mathrm{stat})\pm 0.1(\mathrm{syst})
\mathrm{fb}$.


title:
Measurement of the e+e- Multihadronic Cross Sections below 4.5 GeV with
  BaBar

abstract:
  We present a summary of the hadronic cross section measurements performed
with BaBar at the PEP-II collider via radiative return. BaBar has performed
measurements of exclusive final states containing 3, 4 and 6 hadrons via this
complementary method, as well as a measurement of the proton form factor.


title: Evidence for the Rare Decay B+ --> Ds+ pi0

abstract:
  We have searched for the rare decay B+ --> Ds+ pi0. The analysis is based on
a sample of 232 million Upsilon(4S) --> B anti-B decays collected with the
BABAR detector at the PEP-II e+ e- storage ring. We find 19.6 signal events,
corresponding to a significance of 4.7 sigma. The extracted signal yield
including statistical and systematic uncertainties is 20.1+6.8+0.4 -6.0-1.5,
and we measure B(B+ --> Ds+ pi0) =(1.5 +0.5 -0.4 +- 0.1 +- 0.2) 10^-5, where
the first uncertainty is statistical, the second is systematic, and the last is
due to the uncertainty on the Ds+ decay and its daughter decay branching
fractions.


title: The Super Flavor Factory

abstract:
  The main physics goals of a high luminosity e+e- flavor factory are
discussed, including the possibilities to perform detailed studies of the CKM
mechanism of quark mixing, and constrain virtual Higgs and non-standard model
particle contributions to the dynamics of rare B_u,d,s decays. The large
samples of $D$ mesons and tau leptons produced at a flavor factory will result
in improved sensitivities on D mixing and lepton flavor violation searches,
respectively. One can also test fundamental concepts such as lepton
universality to much greater precision than existing constraints and improve
the precision on tests of CPT from B meson decays. Recent developments in
accelerator physics have demonstrated the feasibility to build an accelerator
that can achieve luminosities of O(10^36) cm^-2 s^-1.


title: chi_{cJ} Decays to h^+h^-h^0

abstract:
  Using a sample of 3 million psi(2S) decays recorded by the CLEO detector, we
study three-body decays of the chi_c0, chi_c1, and chi_c2 produced in radiative
decays of the psi(2S). We consider the final states pi+ pi- eta, K+ K- eta, p
p-bar eta, pi+ pi- eta-prime, K+ K- pi0, p p-bar pi0, pi+ K- K0S, and K+ p-bar
Lambda, measuring branching fractions or placing upper limits. For chi_c1
decays to pi+ pi- eta, K+ K- pi0, and pi+ K- K0S our observed samples are large
enough to indicate the largest contributions to the substructure.


title:
Low-Mass (M<1.2 Gev/c^2) Sigma0 - Meson Produced in the System Pi+Pi-
  from the Reaction np --> np Pi+Pi- at Pn = 5.20 Gev/c^2

abstract:
  The production and properties of the resonances in the system of Pi+Pi- were
studied in the reaction np --> npPi+Pi- at the momentum of incident neutrons
Pn=(5.20 +/- 0.12)GeV/c. In this work in comparison with previous ones we made
more hard selection of events taking into account track measurement precise. In
the distribution of the Pi+Pi- combinations effective masses we have found 8
peculiarities. All the observable peculiarities have spins equal to zero. There
were no corresponding picks in the Pi-PI- and Pi-Pi0 - systems in the reactions
np --> npPi+Pi- Pi- and np --> npPi-Pi0. So, we have observed a row of
resonances with a set of quantum numbers 0+(0++) -- SIGMA0 - mesons decaying on
the channel SIGMA0 --> Pi+Pi-. The obtained in other experiments masses
coincide with the sequence of masses observed in our experiment. Especially
good coincidence can be obtained in the K-matrix approach (see RPP).


title: Summary of Experimental Meson Physics

abstract:
  A summary of the present experimental status of meson physics is presented.
The presentation includes the new results presented at the MESON06 workshop, as
well as other recent experimental developments in the field.


title: Charmonium and Charmonium-like (?) States

abstract:
  The last few years have witnessed a renaissance in the spectroscopy of heavy
quarks. Several long elusive states have now been firmly identified, and
several unexpected states have been reported by the high luminosity experiments
at Belle, Babar, CLEO, and Fermilab. These discoveries have posed important
theoretical questions for our understanding of QCD, and a variety of
theoretical models have been proposed. These developments are critically
discussed.


title:
Separated Structure Functions for the Exclusive Electroproduction of
  $K^+\Lambda$ and $K^+\Sigma^0$ Final States

abstract:
  We report measurements of the exclusive electroproduction of $K^+\Lambda$ and
$K^+\Sigma^0$ final states from a proton target using the CLAS detector at the
Thomas Jefferson National Accelerator Facility. The separated structure
functions $\sigma_T$, $\sigma_L$, $\sigma_{TT}$, and $\sigma_{LT}$ were
extracted from the $\Phi$- and $\epsilon$-dependent differential cross sections
taken with electron beam energies of 2.567, 4.056, and 4.247 GeV. This analysis
represents the first $\sigma_L/\sigma_T$ separation with the CLAS detector, and
the first measurement of the kaon electroproduction structure functions away
from parallel kinematics. The data span a broad range of momentum transfers
from $0.5\leq Q^2\leq 2.8$ GeV$^2$ and invariant energy from $1.6\leq W\leq
2.4$ GeV, while spanning nearly the full center-of-mass angular range of the
kaon. The separated structure functions reveal clear differences between the
production dynamics for the $\Lambda$ and $\Sigma^0$ hyperons. These results
provide an unprecedented data sample with which to constrain current and future
models for the associated production of strangeness, which will allow for a
better understanding of the underlying resonant and non-resonant contributions
to hyperon production.


title: Measurement of B Decays to phi K gamma

abstract:
  We search for the decays B- -> phi K- gamma and B0bar -> phi K0bar gamma in a
data sample of 228 million BBbar pairs collected at the Upsilon(4S) resonance
with the BaBar detector. We measure the branching fraction B(B- -> phi K-
gamma) = (3.5 +/- 0.6 +/- 0.4) x 10^-6 and set an upper limit B(B0bar -> phi
K0bar gamma) < 2.7 x 10^-6 at the 90% confidence level. We also measure the
direct CP asymmetry in B- -> phi K- gamma, A_CP = (-26 +/- 14 +/- 5)%. The
uncertainties are statistical and systematic, respectively.


title: Searches for $D^0$-$\bar{D^0}$ Mixing, Rare Charm and Tau Decays

abstract:
  I discuss the results on $D^{0}$-$\bar{D}^{0}$ mixing through hadronic as
well as semi-leptonic charm decays, rare flavor-changing neutral currents in
the charm sector and the lepton flavor violating $\tau$ decaying to charged
lighter leptons. The results from both BABAR and Belle are presented in this
review.


title: Science Potential of a Deep Ocean Antineutrino Observatory

abstract:
  This paper presents science potential of a deep ocean antineutrino
observatory under development at Hawaii. The observatory design allows for
relocation from one site to another. Positioning the observatory some 60 km
distant from a nuclear reactor complex enables precision measurement of
neutrino mixing parameters, leading to a determination of neutrino mass
hierarchy. At a mid-Pacific location the observatory measures the flux and
ratio of uranium and thorium decay neutrinos from earth's mantle and performs a
sensitive search for a hypothetical natural fission reactor in earth's core. A
subsequent deployment at another mid-ocean location would test lateral
heterogeneity of uranium and thorium in earth's mantle.


title:
Observation of Exclusive Electron-Positron Production in Hadron-Hadron
  Collisions

abstract:
  We present the first observation of exclusive $e^+e^-$ production in
hadron-hadron collisions, using $p\bar{p}$ collision data at
\mbox{$\sqrt{s}=1.96$ TeV} taken by the Run II Collider Detector at Fermilab,
and corresponding to an integrated luminosity of \mbox{532 pb$^{-1}$}. We
require the absence of any particle signatures in the detector except for an
electron and a positron candidate, each with transverse energy {$E_T>5$ GeV}
and pseudorapidity {$|\eta|<2$}. With these criteria, 16 events are observed
compared to a background expectation of {$1.9\pm0.3$} events. These events are
consistent in cross section and properties with the QED process \mbox{$p\bar{p}
\to p + e^+e^- + \bar{p}$} through two-photon exchange. The measured cross
section is \mbox{$1.6^{+0.5}_{-0.3}\mathrm{(stat)}\pm0.3\mathrm{(syst)}$ pb}.
This agrees with the theoretical prediction of {$1.71 \pm 0.01$ pb}.


title: Search for Invisible Decay of the $\Upsilon(1S)$

abstract:
  We report results of a search for the invisible decay of the Upsilon(1S) via
the Upsilon(3S)->pi+pi-Upsilon(1S) transition using a data sample of 2.9
fb^{-1} at the Upsilon(3S) resonance. The data were collected with the Belle
detector at the KEKB asymmetric-energy e+e- collider. No signal is found, and
an upper limit for the branching fraction at the 90% confidence level is
determined to be B(Upsilon(1S)->invisible) < 2.5x10^{-3}.


title: Near threshold eta meson production in dp collisions

abstract:
  Preliminary results of recent measurements of the near threshold eta meson
production in the dp-->dp eta reaction are presented. The experiment was
performed at the COSY-Juelich accelerator with the use of the COSY-11 detection
system. Data were taken for three values of deuteron beam momenta corresponding
to excess energies of 3.2, 6.1 and 9.2 MeV. The energy dependence of the total
cross section confirms a strong effect of the final state interaction.


title: A study of the double hadron neutrinoproduction on nuclei

abstract:
  The nuclear medium influence on the dihadron neutrinoproduction is
investigated for the first time, using the data obtained with SKAT bubble
chamber. An indication is obtained that the nuclear attenuation of the dihadron
is more expressed for kinematically closest hadron pairs. The experimental data
on the dihadron attenuation and on the ratio of the dihadron to single-hadron
yields are compared with predictions of the two-scale string fragmentation
model.

Moments of the Hadronic Invariant Mass Spectrum in B --> X_c l nu Decays
  at Belle

abstract:
  We present a measurement of the hadronic invariant mass squared (M^2_X)
spectrum in charmed semileptonic B meson decays B --> X_c l nu based on 140
fb^-1 of Belle data collected near the Y(4S) resonance. We determine the first,
the second central and the second non-central moments of this spectrum for
lepton energy thresholds ranging between 0.7 and 1.9 GeV. Full correlations
between these measurements are evaluated.


title: A Search for the Rare Leptonic Decays B+ -> mu+ nu and B+ -> e+ nu

abstract:
  We present a search for the decays B+ -> mu+ nu_mu and B+ -> e+ nu_e in a 253
fb-1 data sample collected at the \Upsilon(4S) resonance with the Belle
detector at the KEKB asymmetric-energy B factory. We find no significant
evidence for a signal and set 90% confidence level upper limits of B(B+ -> mu+
nu_mu) < 1.7 x 10^{-6} and B(B+ -> e+ nu_e) < 9.8 x 10^{-7}.


title: New precise determination of the \tau lepton mass at KEDR detector

abstract:
  The status of the experiment on the precise $\tau$ lepton mass measurement
running at the VEPP-4M collider with the KEDR detector is reported. The mass
value is evaluated from the $\tau^+\tau^-$ cross section behaviour around the
production threshold. The preliminary result based on 6.7 pb$^{-1}$ of data is
$m_{\tau}=1776.80^{+0.25}_{-0.23} \pm 0.15$ MeV. Using 0.8 pb$^{-1}$ of data
collected at the $\psi'$ peak the preliminary result is also obtained:
$\Gamma_{ee}B_{\tau\tau}(\psi') = 7.2 \pm 2.1$ eV.

Determination of |Vcb| and m_b from Inclusive B -> X_c l nu and B -> X_s
  gamma Decays at Belle

abstract:
  We present an analysis of the Belle measured moments of the lepton energy and
hadronic mass spectra in B -> X_c l nu decays and the photon energy spectrum in
B -> X_s gamma decays using theoretical expressions derived in the 1S and
kinetic schemes. The magnitude of the Cabibbo-Kobayashi-Maskawa matrix element
Vcb, the b-quark mass and other non-perturbative parameters are extracted. In
the 1S scheme analysis we find |Vcb|=(41.49 +/- 0.52(fit) +/- 0.20(tau_B)) x
10^-3 and m_b^{1S}=(4.729 +/- 0.048) GeV. In the kinetic scheme, we obtain
|Vcb|=(41.93 +/- 0.65(fit) +/- 0.07(alpha_s) +/- 0.63(th)) x 10^-3 and
m_b^{kin}=4.564 +/- 0.076(fit) +/- 0.003(alpha_s) GeV.

Remarks Concerning the Study of Four-Jet Events from Hadronic Decays of
  the Z0

abstract:
  The angular correlations of four-jet events from hadronic decays of the Z0
have been studied in the past mainly to extract from them the fundamental
constants of quantum chromodynamics called colour factors. Previous studies
have used all the available phase-space in order to maximize statistics. In
this note we want to point out the possibility that significant differences
between experiment and theory in restricted regions of phase-space might have
escaped detection. Such differences could be a harbinger of the existence of
new particles. Some preliminary results are presented.


title:
Inclusive $B \to X_c l \nu$ decay spectra at Belle and the determination
  of $|V_{cb}|$

abstract:
  We report measurements of the inclusive electron energy spectrum and hadron
invariant mass spectrum for charmed semileptonic decays of B mesons in a 140
fb^-1 data sample collected with the Belle detector at the KEKB e+e- collider.
We determine the first four central moments and partial branching fraction of
the electron energy spectrum for electron energy thresholds from 0.4 to 2.0
GeV, and the first two central and second non-central moments of the hadron
invariant mass spectrum for lepton energy thresholds from 0.7 to 1.9 GeV. Using
these measurements and Belle measurements of the photon energy moments in B ->
X_s gamma decays, we determine the CKM matrix element |Vcb|, the b quark mass
and higher order non-perturbative parameters that appear in the Heavy Quark
Expansion by performing a global fit analysis in the kinetic mass and 1S
schemes.

Q & A Experiment to Search for Vacuum Dichroism, Pseudoscalar-Photon
  Interaction and Millicharged Fermions

abstract:
  A number of experiments are underway to detect vacuum birefringence and
dichroism -- PVLAS, Q & A, and BMV. Recently, PVLAS experiment has observed
optical rotation in vacuum by a magnetic field (vacuum dichroism). Theoretical
interpretations of this result include a possible pseudoscalar-photon
interaction and the existence of millicharged fermions. Here, we report the
progress and first results of Q & A (QED [quantum electrodynamics] and Axion)
experiment proposed and started in 1994. A 3.5-m high-finesse (around 30,000)
Fabry-Perot prototype detector extendable to 7-m has been built and tested. We
use X-pendulums and automatic control schemes developed by the
gravitational-wave detection community for mirror suspension and cavity
control. To polarize the vacuum, we use a 2.3-T dipole permanent magnet, with
27-mm-diameter clear borehole and 0.6-m field length,. In the experiment, the
magnet is rotated at 5-10 rev/s to generate time-dependent polarization signal
with twice the rotation frequency. Our
ellipsometer/polarization-rotation-detection-system is formed by a pair of
Glan-Taylor type polarizing prisms with extinction ratio lower than 10-8
together with a polarization modulating Faraday Cell with/without a quarter
wave plate. We made an independent calibration of our apparatus by performing a
measurement of gaseous Cotton-Mouton effect of nitrogen. We present our first
experimental results and give a brief discussion of our experimental limit on
pseudo-scalar-photon interaction and millicharged fermions.


title: Measurements of integral muon intensity at large zenith angles

abstract:
  High-statistics data on near-horizontal muons collected with Russian-Italian
coordinate detector DECOR are analyzed. Precise measurements of muon angular
distributions in zenith angle interval from 60 to 90 degrees have been
performed. In total, more than 20 million muons are selected. Dependences of
the absolute integral muon intensity on zenith angle for several threshold
energies ranging from 1.7 GeV to 7.2 GeV are derived. Results for this region
of zenith angles and threshold energies have been obtained for the first time.
The dependence of integral intensity on zenith angle and threshold energy is
well fitted by a simple analytical formula.

Measurement of the Ratio Gamma(KL -> pi+ pi-)/Gamma(KL -> pi e nu) and
  Extraction of the CP Violation Parameter |eta+-|

abstract:
  We present a measurement of the ratio of the decay rates Gamma(KL -> pi+
pi-)/Gamma(KL -> pi e nu), denoted as Gamma(K2pi)/Gamma(Ke3). The analysis is
based on data taken during a dedicated run in 1999 by the NA48 experiment at
the CERN SPS. Using a sample of 47000 K2pi and five million Ke3 decays, we find
Gamma(K2pi)/Gamma(Ke3) = (4.835 +- 0.022(stat) +- 0.016(syst)) x 10^-3. From
this we derive the branching ratio of the CP violating decay KL -> pi+ pi- and
the CP violation parameter |eta+-|. Excluding the CP conserving direct photon
emission component KL -> pi+ pi- gamma, we obtain the results BR(KL -> pi+ pi-)
= (1.941 +- 0.019) x 10^-3 and |eta+-| = (2.223 +- 0.012) x 10^-3.

Strange Quark Contribution to the Proton Spin, from Elastic $\vec{e}p$
  and $\nu p$ Scattering

abstract:
  The strangeness contribution to the vector and axial form factors of the
proton is presented for momentum transfers in the range 0.45 < $Q^2$ < 1.0
GeV$^2$. The results are obtained via a combined analysis of forward-scattering
parity-violating elastic $\vec{e}p$ asymmetry data from the G0 and HAPPEx
experiments at Jefferson Lab, and elastic $\nu p$ and $\bar{\nu}p$ scattering
data from Experiment 734 at Brookhaven National Laboratory. The combination of
the two data sets allows for the simultaneous extraction of $G_E^s$, $G_M^s$,
and $G_A^s$ over a significant range of $Q^2$ for the very first time.
Determination of the strange axial form factor $G_A^s$ is vital to an
understanding of the strange quark contribution to the proton spin.


title: Study of $\bar{B^0}\to {D}^0 \pi^+ \pi^-$ decays

abstract:
  We report the results of a study of neutral B meson decays to the D^0 pi+ pi-
final state, where the D^0 is fully reconstructed. The results are obtained
from an event sample containing 388 million BB-bar -meson pairs collected in
the Belle experiment at the KEKB e^+e^- collider. The total branching fraction
of the three-body decay B(bar{B}^0 -> D^0 pi^+ pi^-)
=(8.4+-0.4(stat.)+-0.8(syst.)) 10^{-4} has been measured. The intermediate
resonant structure of these three-body decays has been studied. From a Dalitz
plot analysis we have obtained the product of the branching fractions for
D^{*+}_2 and D^{*+}_0 production: B(bar{B}^0-> D^{*+}_2 pi^-) B(D_2^{*+}->
D^{0}\pi^+)= (2.15+-0.17(stat.)+-0.29(syst.)+-0.12(mod.))10^{-4}, and
B(bar{B}^0-> D^{*+}_0 pi^-) B(D_0^{*+}-> D^{0} pi^+)=
(0.60+-0.13(stat.)}+-0.15(syst.)+-0.22(mod.))10^{-4}. This is the first
observation of the bar{B}^0-> D^{*+}_0 pi^- decay. The bar{B^0} -> D^0 rho^0
and D^0f_2 branching fractions are measured to be: B(bar{B}^0->D^0
rho^0)=(3.19+-0.20(stat.)+-0.24(syst.)+-0.38(mod.)) 10^{-4},and B(bar{B}^0->
D^0 f_2)=(1.20+-0.18(stat.)+-0.21(syst.)+-0.32(mod.)) 10^{-4}.


title: Recent results from the Belle experiment

abstract:

anti-nu_tau, observations of new resonances X, Y and Z, and the first results
from Upsilon(5S) data collected with the Belle detector at KEKB e+e- collider.


title:
Measurements of branching fractions for inclusive K0~/K0 and K*(892)+-
  decays of neutral and charged D mesons

abstract:
  Using the data sample of about 33 pb-1 collected at and around 3.773 GeV with
the BES-II detector at the BEPC collider, we have studied inclusive K0~/K0 and
K*(892)+- decays of D0 and D+ mesons. The branching fractions for the inclusive
K0~/K0 and K*(892)- decays are measured to be BF(D0 to K0~/K0
X)=(47.6+-4.8+-3.0)%, BF(D+ to K0~/K0 X)=(60.5+-5.5+-3.3)%, BF(D0 to K*-
X)=(15.3+- 8.3+- 1.9)% and BF(D+ to K*- X)=(5.7+- 5.2+- 0.7)%. The upper limits
of the branching fractions for the inclusive K*(892)+ decays are set to be
BF(D0 to K*+ X)<3.6% and BF(D+ to K*+ X) <20.3% at 90% confidence level.


title: Kaon physics: Recent experimental progress

presented.

The Preliminary Result from ($K^0_s\pi^{\pm}$) Spectra in p+a Reaction
  at 10 Gev/C

abstract:
  The experimental data from 2m propane bubble chamber have been analyzed to
search of scalar meson $\kappa$(800) in $K^0_s\pi^{\pm}$ spectra for the
reaction p+A at 10 GeV/c. The $K^0_s\pi^{\pm}$ invariant mass spectra has shown
similarly resonant structures with $M_{K^0_s\pi}$=720,780 and 890 MeV/$c^2$.
The M(890) peak is identified as the well known resonance $K^*$ from PDG.


title: Measurement of the Absolute Branching Fraction of D0 -> K- pi+

abstract:
  We measure the absolute branching fraction for $D0 \to K^{-} \pi^{+}$ using
partial reconstruction of $B0bar \to D^{*+} X \ell^{-} \bar{\nu}_{\ell}$
decays. Only the charged lepton and the soft pion from the decay $D^{*+} \to
D^{0} \pi^{+}$ are used. Based on a data sample of 230 million BBbar pairs
collected at the $\Upsilon(4S)$ resonance with the \babar detector at the
PEP-II asymmetric-energy $B$ Factory at SLAC, we obtain ${\cal B}(\Dz \to \Km
\pip) = (4.025 \pm 0.038 \pm 0.098)%$, where the first error is statistical and
the second error is systematic.


title: B_c and Excited B States - A Tevatron Review

abstract:
  In this paper recent results from the CDF and D0 experiments on heavy flavor

delivered by the Tevatron proton-antiproton collider at the Fermi National
Accelerator Laboratory, Batavia IL, USA.


title:
Longitudinal Spin Asymmetry and Cross Section of Inclusive pi0
  Production in Polarized p+p Collisions at RHIC

abstract:
  We present the first measurement of the cross section and the double
longitudinal spin asymmetry of inclusive pi0 production in polarized p+p
collisions at Sqrt(s) = 200 GeV at mid-rapidity with the STAR detector, using
the barrel electromagnetic calorimeter. The measured cross section is compared
to NLO pQCD calculations and can provide constraints on the pion fragmentation
functions. Fragmentation is studied directly by measuring the momentum fraction
of pi0 in jets, a quantity that is affected by the fragmentation process and
jet reconstruction effects. The double longitudinal spin asymmetry is compared
to NLO pQCD calculations based on different assumptions for the gluon
polarization in the nucleon to provide constraints on delta g/g. At the present
level of statistics the measured asymmetry disfavors a large positive gluon
polarization, but can not yet distinguish between other scenarios.


title:
Double Longitudinal Spin Asymmetries of Inclusive Charged Pion
  Production in Polarized p+p Collisions at 200 GeV

abstract:
  A primary goal of the STAR Spin program at RHIC is the measurement of the
polarized gluon distribution function $\Delta G$, which can be obtained from a
global analysis incorporating measurements of the double spin asymmetry A_{LL}
in various final state channels of polarized p+p collisions. Final states with
large production cross sections such as inclusive jet and hadron production are
analyzed as the program moves towards the measurement of A_{LL} in the
theoretically clean channel of prompt photon production. The channels p+p ->
pi^{+/-} + X are unique in that the ordering of the measurements of A_{LL} in
these two channels is sensitive to the sign of Delta G. Moreover, STAR has
already established the procedure for the identification of charged pions and
the calculation of their production cross-sections over a broad kinematic
range. This contribution will present first measurements of double longitudinal
spin asymmetries for inclusive charged pion production extracted from 3 pb^{-1}
of data at sqrt{s}=200 GeV and 50% beam polarizations. The asymmetries are
calculated over the transverse momentum region 2<p_T<10 GeV/c and compared with
theoretical predictions incorporating several gluon polarization scenarios. A
systematic bias introduced by the selection of charged pions from events
satisfying electromagnetic energy triggers will be discussed and estimated
using Monte Carlo.


title:
Study of the Y (4260) resonance in e+e- collisions with initial state
  radiation at Belle

abstract:
  We present a study of Y(4260) properties using the initial-state radiation
process e^+e^- -> gamma_{ISR} Y(4260). The Y(4260) resonance is reconstructed
in the pi^+ pi^- J/\psi decay mode, using data collected by the Belle detector
at the KEKB e^+e^- collider. We find a significant signal with a central mass
value of (4295 +-10 +10 -3) MeV/c^2 and a width of (133 +-26 +13 -6) MeV/c^2.
We find Gamma_{ee}.B(Y(4260) -> pi^+ pi^- J/\psi) = (8.7 +- 1.1 +0.3 -0.9) eV.
These results are preliminary.


title:
The Main Injector Particle Physics Experiment (MIPP FNAL E-907) at
  Fermilab - status and plans

abstract:
  We describe the status of the Main Injector particle production Experiment
(MIPP) at Fermilab which has to date acquired 18 million events of particle
interactions using (5 GeV/c-120 GeV/c) $\pi^\pm, K^\pm$ and $p^\pm$ beams on
various targets. We describe plans to upgrade the data acquisition speed of
MIPP to make it run 100 times faster which will enable us to obtain particle
production data of unprecdented quality and statistics on a wide variety of
nuclear targets including nitrogen which is of importance to cosmic ray
physics.


title: Photoproduction of events with rapidity gaps between jets at HERA

abstract:
  The photoproduction of dijet events, where the two jets with the highest
transverse energy are separated by a large gap in pseudorapidity, have been
studied with the ZEUS detector using an integrated luminosity of 39 pb$^{-1}$.
Rapidity-gap events are defined in terms of the energy flow between the jets,
such that the total summed transverse energy in this region is less than some
value $E_{\rm T}^{\rm CUT}$. The data show a clear excess over the predictions
of standard photoproduction models. This is interpreted as evidence for a
strongly interacting exchange of a color-singlet object. Monte Carlo models
which include such a color-singlet exchange are able to describe the data.


title: Search for New Phenomena in the CDF Top Quark Sample

abstract:
  We present recent results from CDF in the search for new phenomena appearing
in the top quark samples. These results use data from proton-antiproton
collisions at sqrt{s} = 1.96 TeV corresponding to an integrated luminosity
ranging from 195 pb^-1 to 760 pb^-1. No deviations are observed from the
Standard Model expectations, so upper limits on the size of possible new
phenomena are set.

Azimuthal single-spin asymmetries in semi-inclusive deep-inelastic
  scattering on a transversely polarised hydrogen target

abstract:
  Azimuthal single-spin asymmetries (SSA) in semi-inclusive electroproduction
of charged pions and kaons in deep-inelastic scattering of positrons on a
transversely polarised hydrogen target were observed. SSA amplitudes for both
the Collins and the Sivers mechanism are presented.


title:
Measurement of the Helicity Fractions of W Bosons from Top Quark Decays
  Using Fully Reconstructed top-antitop Events with CDF II

abstract:
  We present a measurement of the fractions F_0 and F_+ of longitudinally
polarized and right-handed W bosons in top quark decays using data collected
with the CDF II detector. The data set used in the analysis corresponds to an
integrated luminosity of approximately 318 pb -1. We select ttbar candidate
events with one lepton, at least four jets, and missing transverse energy. Our
helicity measurement uses the decay angle theta*, which is defined as the angle
between the momentum of the charged lepton in the W boson rest frame and the W
momentum in the top quark rest frame. The cos(theta*) distribution in the data
is determined by full kinematic reconstruction of the ttbar candidates. We find
F_0 = 0.85 +0.15 -0.22 (stat) +- 0.06 (syst) and F_+ = 0.05 +0.11 -0.05 (stat)
+- 0.03 (syst), which is consistent with the standard model prediction. We set
an upper limit on the fraction of right-handed W bosons of F_+ < 0.26 at the
95% confidence level.


title:
Search for single production of scalar leptoquarks in p\bar{p}
  collisions decaying into muons and quarks with the D0 detector

abstract:
  We report on a search for second generation leptoquarks LQ_2 which decay into
a muon plus quark in p\bar{p} collisions at a center-of-mass energy of sqrt{s}
= 1.96 TeV in the D0 detector using an integrated luminosity of about 300 pb-1.
No evidence for a leptoquark signal is observed and an upper bound on the
product of the cross section for single leptoquark production times branching
fraction beta into a quark and a muon was determined for second generation
scalar leptoquarks as a function of the leptoquark mass. This result has been
combined with a previously published D0 search for leptoquark pair production
to obtain leptoquark mass limits as a function of the leptoquark-muon-quark
coupling, lambda. Assuming lambda=1, lower limits on the mass of a second
generation scalar leptoquark are m{LQ_2}>274 GeV and m{LQ_2}>226 GeV for beta=1
and beta=1/2, respectively.


title: Search for techniparticles in e +jets events at D0

abstract:
  We search for the technicolor process ppbar -> rho_T/omega_T ->W+pi_T in
events containing one electron and two jets, in data corresponding to an
integrated luminosity of 390 pb-1, recorded by the D0 experiment at the
Fermilab Tevatron. Technicolor predicts that technipions, pi_T, decay
dominantly into b-bbar, b-cbar, or bbar-c, depending on their charge. In these
events b and c quarks are identified by their secondary decay vertices within
jets. Two analysis methods based on topological variables are presented. Since
no excess above the standard model prediction was found, the result is
presented as an exclusion in the pi_T vs. rho_T mass plane for a given set of
model parameters.


title:
First measurement of low intensity fast neutron background from rock at
  the Boulby Underground Laboratory

abstract:
  A technique to measure low intensity fast neutron flux has been developed.
The design, calibrations, procedure for data analysis and interpretation of the
results are discussed in detail. The technique has been applied to measure the
neutron background from rock at the Boulby Underground Laboratory, a site used
for dark matter and other experiments, requiring shielding from cosmic ray
muons. The experiment was performed using a liquid scintillation detector. A
6.1 litre volume stainless steel cell was filled with an in-house made liquid
scintillator loaded with Gd to enhance neutron capture. A two-pulse signature
(proton recoils followed by gammas from neutron capture) was used to identify
the neutron events from much larger gamma background from PMTs. Suppression of
gammas from the rock was achieved by surrounding the detector with high-purity
lead and copper. Calibrations of the detector were performed with various gamma
and neutron sources. Special care was taken to eliminate PMT afterpulses and
correlated background events from the delayed coincidences of two pulses in the
Bi-Po decay chain. A four month run revealed a neutron-induced event rate of
1.84 +- 0.65 (stat.) events/day. Monte Carlo simulations based on the GEANT4
toolkit were carried out to estimate the efficiency of the detector and the
energy spectra of the expected proton recoils. From comparison of the measured
rate with Monte Carlo simulations the flux of fast neutrons from rock was
estimated as (1.72 +- 0.61 (stat.) +- 0.38 (syst.))*10^(-6) cm^(-2) s^(-1)
above 0.5 MeV.


title:
Measurement of the B+ production cross section in p-pbar collisions at
  sqrt(s) = 1960 GeV

abstract:
  We present a new measurement of the $B^+$ meson differential cross section
$d\sigma/d p_T$ at $\sqrt{s}=1960$ GeV. The data correspond to an integrated
luminosity of 739pb$^{-1}$ collected with the upgraded CDF detector (CDF II) at
the Fermilab Tevatron collider. $B^+$ candidates are reconstructed through the
decay $B^+ \to J/\psi K^+$, with $J/\psi \to \mu^+ \mu^-$. The integrated cross
section for producing $B^+$ mesons with $p_T \geq 6$ GeV/c and $|y| \leq 1$ is
measured to be $2.78 \pm 0.24 \mu$b


title: Measurement of $\psip$ Radiative Decays

abstract:
  Using 14 million psi(2S) events accumulated at the BESII detector, we report
first measurements of branching fractions or upper limits for psi(2S) decays
into gamma ppbar, gamma 2(pi^+pi^-), gamma K_s K^-pi^++c.c., gamma K^+ K^-
pi^+pi^-, gamma K^{*0} K^- pi^+ +c.c., gamma K^{*0}\bar K^{*0}, gamma pi^+pi^-
p pbar, gamma 2(K^+K^-), gamma 3(pi^+pi^-), and gamma 2(pi^+pi^-)K^+K^- with
the invariant mass of hadrons below 2.9GeV/c^2. We also report branching
fractions of psi(2S) decays into 2(pi^+pi^-) pi^0, omega pi^+pi^-, omega
f_2(1270), b_1^\pm pi^\mp, and pi^0 2(pi^+pi^-) K^+K^-.


title:
Branching Fraction Measurements of B+ -> rho+ gamma, B0 -> rho0 gamma,
  and B0 -> omega gamma

abstract:
  We present a study of the decays B+ -> rho+ gamma, B0 -> rho0 gamma, and B0
-> omega gamma. The analysis is based on data containing 347 million BBbar
events recorded with the BaBar detector at the PEP-II asymmetric B factory. We
measure the branching fractions BR(B+ -> rho+ gamma) = (1.10 +0.37/-0.33 +/-
0.09) x 10-6 and BR(B0 -> rho0 gamma) = (0.79 +0.22/-0.20 +/- 0.06) x 10-6, and
set a 90% C.L. upper limit BR(B0 -> omega gamma) < 0.78 x 10-6. We also measure
the isospin-averaged branching fraction BR(B->rho/omega gamma) = (1.25
+0.25/-0.24 +/- 0.09) x 10-6, from which we determine |Vtd/Vts| = 0.200
+0.021/-0.020 +/- 0.015, where the first uncertainty is experimental and the
second is theoretical.


title:
Branching fractions and direct CP asymmetries of charmless decay modes
  at the Tevatron

abstract:
  We present new CDF results on the branching fractions and time-integrated
direct CP asymmetries for $B^{0}$ and $B^{0}_{s}$ decay modes into pairs of
charmless charged hadrons (pion or kaon). The data set for this update amounts
to 1 fb$^{-1}$ of $\bar{p}p$ collisions at $\sqrt{s}=1.96 \rm{TeV}$. We report
the first observation of the $B^{0}_{s} \to K^{-}\pi^{+}$ mode and a
measurement of its branching fraction and direct CP asymmetry. We also observe
for the first time two charmless decays of $b$-baryon: $\Lambda^{0}_{b} \to
p\pi^{-}$ and $\Lambda^{0}_{b} \to pK^{-}$.


title: Anti-Deuteron Production in Upsilon(nS) Decays and the Nearby Continuum

abstract:
  Using CLEO data, we study the production of the anti-deuteron, d-bar, in
Upsilon(nS) resonance decays and the nearby continuum. The branching ratios
obtained are B^dir(Upsilon(1S) --> d-bar X) = (3.36 +- 0.23 +- 0.25) x 10^-5,
  B(Upsilon(1S) --> d-bar X) = (2.86 +- 0.19 +- 0.21) x 10^-5, and
  B(Upsilon(2S) --> d-bar X) = (3.37 +- 0.50 +- 0.25) x 10^-5, where the `dir'
superscript indicates that decays produced via re-annihilation of the b bbar
pair to a gamma* are removed from both the signal and the normalizing number of
Upsilon(1S) decays in order to isolate direct decays of the Upsilon(1S) to ggg,
gg gamma. Upper limits at 90% CL are given for B(Upsilon(4S) --> d-bar X) < 1.3
x 10^-5, and continuum production \sigma(e^+e^- --> d-bar X) < 0.031 pb. The
Upsilon(2S) data is also used to extract a limit on chi_bJ --> d-bar X. The
results indicate enhanced deuteron production in ggg, gg gamma hadronization
compared to gamma* --> q qbar. Baryon number compensation is also investigated
with the large Upsilon(1S) --> d-bar X sample.


title:
Measurement of the B0 --> pi l nu Form-Factor Shape and Branching
  Fraction, and Determination of |Vub| with a Loose Neutrino Reconstruction
  Technique

abstract:
  We report the results of a study of the exclusive charmless semileptonic
decay, B --> pi l nu, undertaken with approximately 227 million BBbar pairs
collected at the Upsilon(4S) resonance with the BaBar detector. The analysis
uses events in which the signal B decays are reconstructed with an innovative
loose neutrino reconstruction technique. We obtain partial branching fractions
in 12 bins of q2, the momentum transfer squared, from which we extract the
f+(q2) form-factor shape and the total branching fraction BF(B0 --> pi l nu) =
(1.46 +- 0.07(stat) +- 0.08(syst)) x 10^-4. Based on a recent unquenched
lattice QCD calculation of the form factor in the range q2 > 16 GeV^2, we find
the magnitude of the CKM matrix element |Vub| to be (4.1 +- 0.2(stat) +-
0.2(syst) +0.6-0.4(FF)) x 10^-3, where the last uncertainty is due to the
normalization of the form factor.


title: Evidence for B0->rho0rho0 Decay and Implications for the CKM Angle alpha

abstract:
  We search for the decays B0->rho0rho0, B0->rho0f0, and B0->f0f0 in a sample
of about 384 million Upsilon(4S)->BBbar decays collected with the BABAR
detector at the PEP-II asymmetric-energy e+e- collider at SLAC. We find
evidence for B0->rho0rho0 with 3.5 sigma significance and measure the branching
fraction BR = (1.07+-0.33+-0.19)10^-6 and longitudinal polarization fraction
f_L = 0.87+-0.13+-0.04, where the first uncertainty is statistical, and the
second is systematic. The uncertainty on the CKM unitarity angle alpha due to
penguin contributions in B-> rho rho decays is 18 degrees at the 1 sigma level.
We also set upper limits on the B0->rho0f0 and B0->f0f0 decay rates.

Determination of Neutrino Mass Hierarchy and Theta_13 with a Remote
  Detector of Reactor Antineutrinos

abstract:
  We describe a method for determining the hierarchy of the neutrino mass
spectrum and theta_13 through remote detection of antineutrinos from a nuclear
reactor. This method utilizing a single, 10-kt scintillating liquid detector at
a distance of 50-64 kilometers from the reactor complex measures mass-squared
differences involving nu_3 with a one (ten) year exposure provided
sin2(2theta_13)>0.05 (0.02). Our technique applies the Fourier transform to the
event rate as a function of neutrino flight distance over energy. Sweeping over
a relevant range of delta-m2 resolves separate spectral peaks for delta-m2_31
and delta-m2_32. For normal (inverted) hierarchy the absolute value of
delta-m2_31 is greater (lesser) than the absolute value of delta-m2_32. This
robust method requires a detector energy resolution of 3.5% divided by the
square root of the scintillation energy.


title: Measurement of K0S, Lambda, Antilambda production at HERA

abstract:
  The production of the neutral strange hadrons $K^{0}_{S}$, $\Lambda$ and
$\bar{\Lambda}$ has been measured in $ep$ collisions at HERA using the ZEUS
detector. Cross sections, baryon-to-meson ratios, relative yields of strange
and charged light hadrons, $\Lambda$ ($\bar{\Lambda}$) asymmetry and
polarization have been measured in three kinematic regions: $Q^2 > 25 \gev^2$;
$5 < Q^2 < 25 \gev^2$; and in photoproduction ($Q^2 \simeq 0$). In
photoproduction the presence of two hadronic jets, each with at least $5 \gev$
transverse energy, was required. The measurements agree in general with Monte
Carlo models and are consistent with measurements made at $e^+ e^-$ colliders,
except for an enhancement of baryon relative to meson production in
photoproduction.


title:
Bottom production cross section from double muonic decays of b-hadrons
  in 920 GeV proton-nucleus collision

abstract:
  The b-bbar production cross section in 920 GeV proton-nucleus fixed target
collisions is measured by observing double muonic decays of b-flavored hadrons
in the kinematic region $-0.3<\xF(\mu)<0.15$.
  A total number of $76\pm12$ b-bbar events is obtained with a likelihood fit
of the signal and background simulated events to the data.
  The resulting cross section is $\sigbb = 16.2 \pm 2.5_{stat} \pm 2.8_{sys}
\nbpn$, or, when combined with a previous Hera-B measurement of similar
precision, $\sigbb = 15.4 \pm 1.7_{stat} \pm 1.2_{sys}^{uncorr.} \pm
1.9_{sys}^{corr.} \nbpn$, which is consistent with recent NLO calculations.


title: Long Baseline Neutrino Physics in the U.S

abstract:
  Long baseline neutrino oscillation physics in the U.S. is centered at the
Fermi National Accelerator Laboratory (FNAL), in particular at the Neutrinos at
the Main Injector (NuMI) beamline commissioned in 2004-2005. Already, the MINOS
experiment has published its first results confirming the disappearance of
$\nu_\mu$'s across a 735 km baseline. The forthcoming NO$\nu$A experiment will
search for the transition $\nu_\mu\to\nu_e$ and use this transition to
understand the mass heirarchy of neutrinos. These, as well as other conceptual
ideas for future experiments using the NuMI beam, will be discussed. The
turn-on of the NuMI facility has been positive, with over 310 kW beam power
achieved. Plans for increasing the beam intensity once the Main Injector
accelerator is fully-dedicated to the neutrino program will be presented.


title:
Measurement of the Top-Quark Mass in All-Hadronic Decays in p pbar
  Collisions at CDF II

abstract:
  We present a measurement of the top-quark mass, $M_{\mathrm{top}}$, in the
all-hadronic decay channel $t\bar{t} \to W^+b W^- \bar{b} \to q_1\bar{q}_2 b
q_3 \bar{q}_4 \bar{b}$. The analysis is performed using 310 pb$^{-1}$ of
$\sqrt{s}$=1.96 TeV $p\bar{p}$ collisions collected with the CDF II detector
using a multi-jet trigger. The mass measurement is based on an event-by-event
likelihood which depends on both the sample purity and the value of the
top-quark mass, using 90 possible jet-to-parton assignments in the six-jet
final state. The joint likelihood of 290 selected events yields a value of
$M_{\mathrm{top}}$=177.1 $\pm$ 4.9 (stat.) $\pm$ 4.7 (syst.) GeV/$c^2$.


title: Experimental Status of Exotic Mesons and the GlueX Experiment

abstract:
  One of the unanswered and most fundamental questions in physics regards the
nature of the confinement mechanism of quarks and gluons in QCD. Exotic hybrid
mesons manifest gluonic degrees of freedom and their spectroscopy will provide
the data necessary to test assumptions in lattice QCD and the specific
phenomenology leading to confinement. Within the past two decades a number of
experiments have put forth tantalizing evidence for the existence of exotic
hybrid mesons in the mass range below 2 GeV. This talk represents an overview
of the available data and what has been learned. In looking toward the future,
the GlueX experiment at Jefferson Laboratory represents a new initiative that
will perform detailed spectroscopy of the light-quark meson spectrum. This
experiment and its capabilities will be reviewed.


title: Experimental results on searches beyond the Standard Model

abstract:
  Recent results for direct searches for physics beyond the Standard Model are
reviewed. The results include Tevatron II data up to 1.2 fb-1 and HERA results
up to 350 pb-1. Searches for Supersymmetry, for compositeness and for large
extra dimensions are presented. The excess of events with an isolated lepton
and high missing transverse momentum at HERA is discussed.


title:
Measurement of the pseudoscalar mixing angle and $\eta^{\prime}$
  gluonium content with KLOE detector

abstract:
  We have measured the ratio $R_{\phi}=BR(\phi \to \eta^{\prime}
\gamma)/BR(\phi \to \eta \gamma)$ by looking for the radiative decays $\phi \to
\eta^{\prime} \gamma$ and $\phi \to \eta \gamma$ in the final states
$\pi^+\pi^-$ 7 $\gamma$'s and 7 $\gamma$'s respectively, in a sample of $\sim
1.3\cdot 10^{9}$ $\phi$ mesons produced at the Frascati $\phi$-factory. We
obtain $R_{\phi}=(4.77\pm0.09_{stat}\pm0.19_{sys})\cdot 10^{-3}$ from which we
derive $BR(\phi \to \eta^{\prime}
\gamma)=(6.20\pm0.11_{stat}\pm0.25_{sys})\cdot 10^{-5}$. In the hypothesis of
no gluonium content we extract the pseudoscalar mixing angle in the
quark-flavor basis $\phi_P=(41.4\pm0.3_{stat}\pm0.7_{sys}\pm0.6_{th})^{\circ}$.
Combining the value of $R_{\phi}$ with other constraints, we estimate the
gluonium fractional content of $\eta^{\prime}$ meson as $Z^2 = 0.14\pm0.04$ and
the mixing angle $\phi_P = (39.7\pm0.7)^{\circ}$.


title:
Measurements of Transverse Spin Effects with the Forward Pion Detector
  of STAR

abstract:
  Measurements by the STAR collaboration of neutral pion production at large
Feynman x (x_F) in the first polarized proton collisions at $\sqrt{s}=200$ GeV
were reported previously. Cross sections measured at $\eta=3.3$, 3.8 and 4.0
are found to be consistent with next-to-leading order perturbative QCD
calculations. The analyzing power is consistent with zero at negative x_F and
at positive x_F up to ~0.3, then grows more positive with increasing x_F. This
behavior can be described by phenomenological models including the Sivers
effect, the Collins effect or higher twist contributions in the initial and
final states. Forward calorimetry at STAR has been extended, and there are
plans for further expansion. An integrated luminosity of 6.8 pb^${-1}$ with
average beam polarization of 60% from online polarimetry measurements was
sampled with the upgraded FPD in the 2006 RHIC run. This data sample will allow
for a detailed map of the \pi^0 analyzing power over kinematic variables
bounded by 0.3 < x_F < 0.6 and 1.2 < p_T < 5.0 GeV/c at $\sqrt{s}=200$ GeV. The
expanded FPD has observed multi-photon final states expected to have "jet-like"
characteristics. The transverse spin dependence of jet-like events can
discriminate between the Collins and Sivers effects and lead to further
progress in understanding the origin of single spin asymmetries in forward
particle production. Data were also obtained at $\sqrt{s}=62.4$ GeV for x_F ->
1 to test predictions based on phenomenological fits to earlier STAR results.
Recent results, the status of the analysis of 2006 run data and near-term plans
will be discussed.


title:
Double Helicity Asymmetry and Cross Section for eta Production in
  Polarized pp Collisions at PHENIX

abstract:
  Measurements of double helicity asymmetries for inclusive hadron production
in polarized proton-proton collisions are sensitive to spin-dependent parton
distribution functions, in particular to the gluon distribution, Delta g. This
study presents the double helicity asymmetry and the cross section for eta
production. The cross section measurement yields valuable data for the
extraction of the fragmentation functions, which are unknown at present but are
a prerequisite for the extraction of the spin-dependent parton distribution
functions.


title:
A Non-parametric Approach to Measuring the \kpi{} Amplitudes in
  \dpkkpi{} Decay

abstract:
  Using a large sample of \dpkkpi{} decays collected by the FOCUS
photoproduction experiment at Fermilab, we present the first non-parametric
analysis of the \kpi{} amplitudes in \dpkkpi{} decay. The technique is similar
to the technique used for our non-parametric measurements of the \krzmndk{}
form factors. Although these results are in rough agreement with those of E687,
we observe a wider S-wave contribution for the \ksw{} contribution than the
standard, PDG \cite{pdg} Breit-Wigner parameterization. We have some weaker
evidence for the existence of a new, D-wave component at low values of the $K^-
\pi^+$ mass.


title:
Transverse Single Spin Asymmetry Measurement with J/Psi in Polarized p+p
  Collisions at RHIC

abstract:
  The PHENIX experiment has measured transverse single spin asymmetry of
J/$\Psi$ in polarized p+p collisions at forward rapidity at $\sqrt{s}=200$ GeV.
The data were collected from year 2006 run of RHIC with average beam
polarization of 56%. At RHIC energy, heavy quark production is dominated by
gluon gluon interaction. Therefore, the transverse single spin asymmetry in
J/$\Psi$ production can provide a clean measurement of the gluon Sivers
distribution function.


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

abstract:
  This note presents a combination of published and preliminary electroweak
results from the four LEP collaborations ALEPH, DELPHI, L3 and OPAL based on
electron-positron collision data taken at centre-of-mass energies above the
Z-pole, $130 \GeV$ to $209 \GeV$ (\LEPII), as prepared for the 2006 summer
conferences. Averages are derived for di-fermion cross sections and
forward-backward asymmetries, photon-pair, W-pair, Z-pair, single-W and
single-Z cross sections, electroweak gauge boson couplings, W mass and width
and W decay branching ratios. An investigation of the interference of photon
and Z-boson exchange is presented, and colour reconnection and Bose-Einstein
correlation analyses in W-pair production are combined. The main changes with
respect to the experimental results presented in 2005 are new preliminary
combinations of final {\LEPII} results on the mass and width of the W boson.
Including the precision electroweak measurements performed at the Z pole
published recently, the results are compared with precise electroweak
measurements from other experiments, notably CDF and D{\O}at the Tevatron.
Constraints on the input parameters of the Standard Model are derived from the
results obtained in high-$Q^2$ interactions, and used to predict results in
low-$Q^2$ experiments, such as atomic parity violation, M{\"o}ller scattering,
and neutrino-nucleon scattering.


title:
Longitudinal Spin Transfer in Inclusive $\Lambda$ and $\bar \Lambda$
  Production in Polarized Proton-proton Collisions at $\sqrt s$ =200 GeV

abstract:
  This contribution reports on a proof-of-principle measurement of the
longitudinal spin transfer $D_{LL}$ in inclusive $\Lambda$ and $\bar \Lambda$
production in polarized proton-proton collisions at a center of mass energy
$\sqrt{s}$ = 200 GeV. The data sample consists of about 3 $\times$ $10^6$
minimum bias events collected in the year 2005 by the STAR experiment at RHIC
with proton beam polarizations of up to 50%. The $\Lambda$($\bar \Lambda$)
candidates are reconstructed at mid-rapidity ($|\eta|<1$) using the STAR Time
Projection Chamber via the dominant decay channel $\Lambda\to p \pi^-$ ($\bar
\Lambda \to \bar p \pi^+$). Their mean transverse momentum $p_T$ is about 1.3
GeV/c and longitudinal momentum fraction $x_F = 7.5 \times 10^{-3}$ . The
longitudinal $\Lambda$($\bar \Lambda$) polarization is determined using a
method in which the detector acceptance mostly cancels.


title:
Measurement of Sivers Asymmetries for Di-jets in \sqrt{s}=200 GeV pp
  Collisions at STAR

abstract:
  Measurement of the transverse spin dependence of the di-jet opening angle in
pp collisions at sqrt{s}=200 GeV has been performed by the STAR collaboration.
An analyzing power consistent with zero has been observed over a broad range in
pseudorapidity sum of the two jets with respect to the polarized beam
direction. A non-zero (Sivers) correlation between transverse momentum
direction of partons in the initial state and transverse spin orientation of
the parent proton has been previously observed in semi-inclusive deep inelastic
scattering (SIDIS).
  The present measurements are much smaller than deduced from predictions made
for STAR di-jets based on non-zero quark Sivers functions deduced from SIDIS,
and furthermore indicate that gluon Sivers asymmetries are comparably small.
