title: Results on QCD Physics from the CDF-II Experiment

abstract:
  In this paper we review a selection of recent results obtained, in the area
of QCD physics, from the CDF-II experiment that studies $p\bar{p}$ collisions
at $\sqrt{s}$=1.96 TeV provided by the Fermilab Tevatron Collider. All results
shown correspond to analysis performed using the Tevatron Run II data samples.
In particular we will illustrate the progress achieved and the status of our
studies on the following QCD processes: jet inclusive production, using
different jet clustering algorithm, $W(\to e \nu_e)+ $jets and $Z(\to e^+ e^-)+
$jets production, $\gamma+b-$jet production, dijet production in double pomeron
exchange and finally exclusive $e^+e^-$ and $\gamma \gamma$ production. No
deviations from the Standard Model have been observed so far.


title: Spin physics with light and heavy neutral mesons at Protvino

abstract:
  PROZA-M experiment results as well the proposal of a new spin program with
the use of a polarized proton beam are presented. Significant asymmetries were
observed in inclusive $\pi^0$ production. The new program proposes to study a
wealth of single- and double-spin observables in various reactions using
longitudinally and transversely polarized proton beams at U70. The main goal is
to define gluon contribution to nucleon spin by measuring double-spin asymmetry
in charmonium production.


title:
Single spin asymmetries in inclusive $\pi^0$ production in $p+p$ and
  $\pi^-+p$ interactions at 40-70 GeV

abstract:
  We present recent results of single-spin asymmetry $A_N$ measurements in
$\pi^0$ inclusive production. Asymmetry was measured in $\pi^-p$ and $pp$
interactions at 40 and 70 GeV correspondingly. Significant asymmetry was
observed in the polarized target fragmentation region. The results are in
agreement with "universal threshold" of single-spin asymmetry.


title:
Measurement of the ppbar to ttbar production cross section at
  sqrt(s)=1.96 TeV in the fully hadronic decay channel

abstract:
  A measurement of the top quark pair production cross section in proton
anti-proton collisions at an interaction energy of sqrt(s)=1.96 TeV is
presented. This analysis uses 405 pb-1 of data collected with the D0 detector
at the Fermilab Tevatron Collider. Fully hadronic ttbar decays with final
states of six or more jets are separated from the multijet background using
secondary vertex tagging and a neural network. The ttbar cross section is
measured as sigma(ttbar)=4.5 -1.9 +2.0 (stat) -1.1 +1.4 (syst) +/- 0.3 (lumi)
pb for a top quark mass of m(t) = 175 GeV/c^2.

Conversion efficiency and luminosity for gamma-proton colliders based on
  the LHC-CLIC or LHC-ILC QCD Explorer scheme

abstract:
  Gamma-proton collisions allow unprecedented investigations of the low x and
high $Q^{2}$ regions in quantum chromodynamics. In this paper, we investigate
the luminosity for "ILC"$\times$LHC ($\sqrt{s_{ep}}=1.3$ TeV) and
"CLIC"$\times$LHC ($\sqrt{s_{ep}}=1.45$ TeV) based $\gamma p$ colliders. Also
we determine the laser properties required for high conversion efficiency.


title: New charm resonances

abstract:
  This paper provides a short review of new states carrying a charm quark(s)
which were observed in the recent few years at B factories. The following new
particles are discussed: X(3872), Y(3940), X(3940), \chi_c^{\prime}(3930),
Y(4260), h_c, D_{sJ}, \Lambda_c(2940), \Sigma_c(2880), \Xi_{cx}(2980),
\Xi_{cx}(3077) and \Omega_c^*.


title:
Measurement of the branching ratios of the decays Xi0 --> Sigma+ e-
  nubar and anti-Xi0 --> anti-Sigma+ e+ nu

abstract:
  From 56 days of data taking in 2002, the NA48/1 experiment observed 6316 Xi0
--> Sigma+ e- nubar candidates (with the subsequent Sigma+ --> p pi0 decay) and
555 anti-Xi0 --> anti-Sigma+ e+ nu candidates with background contamination of
215+-44 and 136+-8 events, respectively. From these samples, the branching
ratios BR(Xi0 --> Sigma+ e- nubar)= (2.51+-0.03stat+-0.09syst)E(-4) and
BR(anti-Xi0 --> anti-Sigma+ e+ nu)= (2.55+-0.14stat+-0.10syst)E(-4) were
measured allowing the determination of the CKM matrix element |Vus| =
0.209+0.023-0.028. Using the Particle Data Group average for |Vus| obtained in
semileptonic kaon decays, we measured the ratio g1/f1 = 1.20+-0.05 of the
axial-vector to vector form factors.


title:
Combined D0 and CDF Upper Limits on Standard-Model Higgs-Boson
  Production

abstract:
  We combine results of CDF and D0 searches for a Standard-Model Higgs boson in
data from ppbar collisions at the Fermilab Tevatron with sqrt(s) = 1.96 TeV.
With 260-950 pb-1 collected at D0, and 360-1000 pb-1 collected at CDF, the
95%CL upper limits are a factor of 10.4(3.8) higher than the expected cross
section for mH =115(160) GeV/c2. This result extends significantly the
individual limits of each experiment.


title: Inclusive Production of Charged Hadrons in Photon-Photon Collisions

abstract:
  The inclusive production of charged hadrons in the collisions of quasi-real
photons e+e- -> e+e- +X has been measured using the OPAL detector at LEP. The
data were taken at e+e- centre-of-mass energies from 183 to 209 GeV. The
differential cross-sections as a function of the transverse momentum and the
pseudorapidity of the hadrons are compared to theoretical calculations of up to
next-to-leading order (NLO) in the strong coupling constant alpha{s}. The data
are also compared to a measurement by the L3 Collaboration, in which a large
deviation from the NLO predictions is observed.


title:
Searches and Prospects for the Standard Model Higgs boson at the
  Tevatron

abstract:
  We summarize the status of SM Higgs boson searches at the Fermilab Tevatron
performed by the CDF and D{\O}collaborations, with an emphasis on measurements
at large Higgs mass, and derive sensitivity prospects for the upcoming increase
in integrated luminosity.


title: Toward CP-even Neutrino Beam

abstract:
  The best method of measuring CP violating effect in neutrino oscillation
experiments is to construct and use a neutrino beam made of an ideal mixture of
$\bar{\nu}_e$ and $\nu_e$ of monochromatic lines. The conceptual design of such
a beam is described, together with how to measure the CP-odd quantity. We
propose to exploit an accelerated unstable hydrogen-like heavy ion in a storage
ring, whose decay has both electron capture and bound beta decay with a
comparable fraction.

Improved study of a possible Theta+ production in the pp -> p K0 sigma+
  reaction with the COSY-TOF spectrometer

abstract:
  The pp -> p K0 Sigma+ reaction was investigated with the TOF spectrometer at
COSY at 3.059 GeV/c incident beam momentum. The main objective was to clarify
whether or not a narrow exotic S = +1 resnance, the Theta+ pentaquark, is
populated at 1.53 GeV/c2 in the K0 p subsystem with a data sample of much
higher statistical significance compared to the previously reported data in
this channel. An analysis of these data does not confirm the existence of the
Theta+ pentaquark. This is expressed as an upper limit for the cross section
sigma (pp -> p K0 Sigma+) < 0.15 microbarn at the 95 percent confidence level.


title:
TOTEM: The experiment to measure the total proton-proton cross section
  at LHC

abstract:
  The current large uncertainty on the extrapolation of the proton-proton total
cross section at the LHC energy will be resolved by the precise measurement by
the TOTEM experiment. Its accurate studies on the basic properties of
proton-proton collisions at the maximum accelerator energy could provide a
significant contribution to the understanding of cosmic ray physics.


title:
Measurements of CP-Violating Asymmetries in B0 to a1(1260)^{+-} pi^{-+}
  Decays

abstract:
  We present measurements of CP-violating asymmetries in the decay B0 ->
a_1(1260)^{+-} pi^{-+} with a_1(1260)^{+-} -> pi^{-+} pi^{+-} pi^{+-}. The data
sample corresponds to 384 million B B-bar pairs collected with the BaBar
detector at the PEP-II asymmetric B-factory at SLAC. We measure the
CP-violating asymmetry A^{a_1 \pi}_{CP}=-0.07+-0.07+-0.02, the mixing-induced
CP violation parameter S_{a_1 \pi}= 0.37 +-0.21+-0.07, the direct CP violation
parameter C_{a_1 \pi}=-0.10+-0.15+-0.09, and the parameters \Delta C_{a_1
\pi}=0.26+-0.15+-0.07 and \Delta S_{a_1\pi}=-0.14+-0.21+-0.06. From these
measured quantities we determine the angle \alpha_{\rm eff}= 78.6^{\circ} +-
7.3^{\circ}.


title: Search for Invisible Decays of the Upsilon(1S) Resonance

abstract:
  We present a measurement of the branching fraction of invisible Upsilon(1S)
decays, using 1.2 fb^{-1} of data collected at the Upsilon(2S) resonance with
the CLEO III detector at CESR. After subtracting expected backgrounds from
events that pass selection criteria for invisible Upsilon(1S) decay in
Upsilon(2S) -> pi+ pi- Upsilon(1S), we deduce a 90% C.L. upper limit of
B[Upsilon(1S) -> invisible] < 0.39%.


title:
Evidence for production of single top quarks and first direct
  measurement of |Vtb|

abstract:
  The D0 Collaboration presents first evidence for the production of single top
quarks at the Fermilab Tevatron ppbar collider. Using a 0.9 fb^-1 dataset, we
apply a multivariate analysis to separate signal from background and measure
sigma(ppbar->tb+X,tqb+X) = 4.9 +- 1.4 pb. The probability to measure a cross
section at this value or higher in the absence of signal is 0.035%,
corresponding to a 3.4 standard deviation significance. We use the cross
section measurement to directly determine the CKM matrix element that describes
the Wtb coupling and find 0.68 < |Vtb| <= 1 at 95% C.L. within the standard
model.


title: Analysis of the Quantum Numbers $J^{PC}$ of the X(3872) Particle

abstract:
  We present an analysis of angular distributions and correlations of the
X(3872) particle in the exclusive decay mode X(3872)->J/psi pi+ pi- with
J/psi->mu+ mu-. We use 780 pb -1 of data from ppbar collisions at sqrt{s} =
1.96 TeV collected with the CDF II detector at the Fermilab Tevatron. We derive
constraints on spin, parity, and charge conjugation parity of the X(3872)
particle by comparing measured angular distributions of the decay products with
predictions for different JPC hypotheses. The assignments JPC = 1++ and 2-+ are
the only ones consistent with the data.


title:
Measurements of the continuum $R_{\rm uds}$ and $R$ values in $e^+e^-$
  annihilation in the energy region between 3.650 and 3.872 GeV

abstract:
  We report measurents of the continuum $R_{\rm uds}$ near the center-of-mass
energy of 3.70 GeV, the $R_{{\rm uds(c)}+\psi(3770)}(s)$ and the $R_{\rm
had}(s)$ values in $e^+e^-$ annihilation at 68 energy points in the energy
region between 3.650 and 3.872 GeV with the BES-II detector at the BEPC
Collodier. We obtain the $R_{\rm uds}$ for the continuum light hadron
(containing u, d and s quarks) production near the $D\bar D$ threshold to be
$R_{\rm uds}=2.141 \pm 0.025 \pm 0.085$.


title: Measurements of Delta G/G

abstract:
  Our present information on the gluon polarisation Delta g/g is reviewed. The
data from fixed-target lepton-nucleon experiments are in context with the
recent data from the RHIC polarised pp collider. The main tools to study Delta
g/g in lepton-nucleon scattering are scaling violations of the g_1 structure
functions and longitudinal spin asymmetries in hadron production. Results from
high-p_T hadron pairs, inclusive hadrons as well as open-charm production are
discussed. At RHIC the most precise data presently came from inclusive pi^0 and
jet production. All data indicate that the gluon polarisation is small compared
to earlier expectations, but still can make a major contribution to the nucleon
spin.


title:
Precison Measurements of the Mass, the Widths of $\psi(3770)$ Resonance
  and the Cross Section $\sigma[e^+e^-\to \psi(3770)]$ at $E_{\rm cm}=3.7724$
  GeV

abstract:
  By analyzing the $R$ values measured at 68 energy points in the energy region
between 3.650 and 3.872 GeV reported in our previous paper, we have precisely
measured the mass, the total width, the leptonic width and the leptonic decay
branching fraction of the $\psi(3770)$ to be ${M}_{\psi(3770)}=3772.4 \pm 0.4
\pm 0.3$ MeV, $\Gamma_{\psi(3770)}^{\rm tot} = 28.6 \pm 1.2 \pm 0.2$ MeV,
$\Gamma_{\psi(3770)}^{ee} = 279 \pm 11 \pm 13$ eV and $B[\psi(3770)\to
e^+e^-]=(0.98\pm 0.04\pm 0.04)\times 10^{-5}$, respectively, which result in
the observed cross section $\sigma^{\rm obs}[e^+e^-\to \psi(3770)]=7.25\pm 0.27
\pm 0.34$ nb at $\sqrt{s}=3772.4$ MeV. We have also measured $R_{\rm
uds}=2.121\pm 0.023 \pm 0.084$ for the continuum light hadron production in the
region from 3.650 to 3.872 GeV.


title: Summary of MACRO results on exotic physics

abstract:
  MACRO was a multi-purpose experiment that took data from 1989 to 2000, at the
underground Laboratory of Gran Sasso (Italy). MACRO gave important
results/limits concerning: (i) the oscillation of atmospheric neutrinos, also
in the non-conventional scenario of violations of Lorentz invariance, (ii) the
searches for exotic particles (supermassive GUT magnetic monopoles,
nuclearites, WIMPs), (iii) muon physics and astrophysics. A summary of the
MACRO results will be presented and discussed, focusing the attention on the
exotica searches.


title:
Cross Section Measurements of High-$p_T$ Dilepton Final-State Processes
  Using a Global Fitting Method

abstract:
  We present a new method for studying high-$p_T$ dilepton events
($e^{\pm}e^{\mp}$, $\mu^{\pm}\mu^{\mp}$, $e^{\pm}\mu^{\mp}$) and simultaneously
extracting the production cross sections of $p\bar{p} \to t\bar{t}$, $p\bar{p}
\to W^+W^-$, and $p\bar{p} \to \ztt$ at a center-of-mass energy of $\sqrt{s} =
1.96$ TeV. We perform a likelihood fit to the dilepton data in a parameter
space defined by the missing transverse energy and the number of jets in the
event. Our results, which use $360 {\rm pb^{-1}}$ of data recorded with the CDF
II detector at the Fermilab Tevatron Collider, are $\sigma(t\bar{t}) =
8.5_{-2.2}^{+2.7}$ pb, $\sigma(W^+W^-) = 16.3^{+5.2}_{-4.4}$ pb, and
$\sigma(\ztt) =291^{+50}_{-46}$ pb.


title:
Beam-Spin Asymmetries in the Azimuthal Distribution of Pion
  Electroproduction

abstract:
  A measurement of the beam-spin asymmetry in the azimuthal distribution of
pions produced in semi-inclusive deep-inelastic scattering off protons is
presented. The measurement was performed using the {HERMES} spectrometer with a
hydrogen gas target and the longitudinally polarized 27.6 GeV positron beam of
HERA. The sinusoidal amplitude of the dependence of the asymmetry on the angle
$\phi$ of the hadron production plane around the virtual photon direction
relative to the lepton scattering plane was measured for $\pi^+,\pi^-$ and
$\pi^0$ mesons. The dependence of this amplitude on the Bjorken scaling
variable and on the pion fractional energy and transverse momentum is
presented. The results are compared to theoretical model calculations.


title:
Precision measurement of the top quark mass from dilepton events at CDF
  II

abstract:
  We report a measurement of the top quark mass, M_t, in the dilepton decay
channel of $t\bar{t}\to b\ell'^{+}\nu_{\ell'}\bar{b}\ell^{-}\bar{\nu}_{\ell}$
using an integrated luminosity of 1.0 fb^{-1} of p\bar{p} collisions collected
with the CDF II detector. We apply a method that convolutes a leading-order
matrix element with detector resolution functions to form event-by-event
likelihoods; we have enhanced the leading-order description to describe the
effects of initial-state radiation. The joint likelihood is the product of the
likelihoods from 78 candidate events in this sample, which yields a measurement
of M_{t} = 164.5 \pm 3.9(\textrm{stat.}) \pm 3.9(\textrm{syst.})
\mathrm{GeV}/c^2, the most precise measurement of M_t in the dilepton channel.


title:
Measurement of the Top Quark Mass in ppbar Collisions at sqrt(s) = 1.96
  TeV using the Decay Length Technique

abstract:
  We report the first measurement of the top quark mass using the decay length
technique in ppbar collisions at a center-of-mass energy of 1.96 TeV. This
technique uses the measured flight distance of the b hadron to infer the mass
of the top quark in lepton plus jets events with missing transverse energy. It
relies solely on tracking and avoids the jet energy scale uncertainty that is
common to all other methods used so far. We apply our novel method to a 695
pb^-1 data sample recorded by the CDF II detector at Fermilab and extract a
measurement of m_t = 180.7^{+15.5}_{-13.4} (stat.) \pm 8.6 (syst.) GeV/c^2.
While the uncertainty of this result is larger than that of other measurements,
the dominant uncertainties in the decay length technique are uncorrelated with
those in other methods. This result can help reduce the overall uncertainty
when combined with other existing measurements of the top quark mass.


title: Confirmation of a pi_1^0 Exotic Meson in the \eta \pi^0 System

abstract:
  The exclusive reaction $\pi^- p \to \eta \pi^0 n$, $\eta \to \pi^+ \pi^-
\pi^0$ at 18 GeV$/c$ has been studied with a partial wave analysis on a sample
of 23~492 $\eta \pi^0 n$ events from BNL experiment E852. A mass-dependent fit
is consistent with a resonant hypothesis for the $P_+$ wave, thus providing
evidence for a neutral exotic meson with $J^{PC} = 1^{-+}$, a mass of $1257 \pm
20 \pm 25$ MeV$/c^2$, and a width of $354 \pm 64 \pm 60$ MeV$/c^2$. New
interpretations of the meson exotics in neutral $\eta \pi^0$ system observed in
E852 and Crystal Barrel experiments are discussed.


title: Search for the exotic $\Theta^+$ resonance in the NOMAD experiment

abstract:
  A search for exotic Theta baryon via Theta -> proton +Ks decay mode in the
NOMAD muon neutrino DIS data is reported. The special background generation
procedure was developed. The proton identification criteria are tuned to
maximize the sensitivity to the Theta signal as a function of xF which allows
to study the Theta production mechanism. We do not observe any evidence for the
Theta state in the NOMAD data. We provide an upper limit on Theta production
rate at 90% CL as 2.13 per 1000 of neutrino interactions.


title:
Search for Two-Particle Muon Decay to Positron and Goldstone Massless
  Boson (FAMILON)

abstract:
  The experimental test of possible expansion for the Higgs sector is proposed.
The lepton family violation will be studied. To reach this goal we are going to
carry out the search for the scalar Goldstone boson in the neutrinoless muon
decay mu+ to e+ and alpha. The asymmetry of the muon decay near the high energy
edge of Michel spectrum is to be measured. To examine previous TRIUMF data the
experiment FAMILON is prepared at the surface muon beam of JINR (Dubna)
accelerator. The setup consist of the precision magnetic spectrometer and the
device for muSR - analysis.


title: Recent results from the STAR spin program at RHIC

abstract:
  The STAR experiment uses polarized p+p collisions at RHIC to determine the
contributions to the spin of the proton from gluon spin and from orbital
angular momentum of the quarks and gluons. Selective STAR measurements of the
longitudinal double spin asymmetry for inclusive jet and inclusive hadron
production are presented here. In addition, we report measurements of the
transverse spin asymmetry for di-jet production at mid-rapidity and the
transverse single-spin asymmetry for forward pi0 production


title:
Search for Exotic S=-2 Baryons in proton-antiproton Collisions at
  sqrt(s) = 1.96 TeV

abstract:
  A search for a manifestly exotic S=-2 baryon state decaying to Xi- pi-, and
its neutral partner decaying to Xi- pi+, has been performed using 220 pb^(-1)
of pp= collisions at sqrt(s)=1.96 TeV collected by the Collider Detector at
Fermilab. The Xi trajectories were measured in a silicon tracker before their
decay, resulting in a sample with low background and excellent position
resolution. No evidence was found for S=-2 pentaquark candidates in the
invariant mass range of 1600--2100 MeV/c^2 Upper limits on the product of
pentaquark production cross section times its branching fraction to Xi-
pi^{+,-}, relative to the cross section of the well established Xi(1530)
resonance, are presented for neutral and doubly negative candidates with pT>2
GeV/c and |y|<1 as a function of pentaquark mass. At 1862 MeV/c^2, these upper
limits for neutral and doubly negative final states were found to be 3.2% and
1.7% at the 90% confidence level, respectively.


title: Study of the D^0 \to pi^-pi^+pi^-pi^+ decay

abstract:
  Using data from the FOCUS (E831) experiment at Fermilab, we present new
measurements for the Cabibbo-suppressed decay mode $D^0 \to
\pi^-\pi^+\pi^-\pi^+$. We measure the branching ratio $\Gamma(D^0 \to\pi^+\pi^-
\pi^+\pi^-)/\Gamma(D^0 \to K^-\pi^+\pi^-\pi^+) = 0.0914 \pm 0.0018 \pm 0.0022$.
An amplitude analysis has been performed, a first for this channel, in order to
determine the resonant substructure of this decay mode. The dominant component
is the decay $D^0 \to a_1(1260)^+ \pi^-$, accounting for 60% of the decay rate.
The second most dominant contribution comes from the decay $D^0 \to
\rho(770)^0\rho(770)^0$, with a fraction of 25%. We also study the $a_1(1260)$
line shape and resonant substructure. Using the helicity formalism for the
angular distribution of the decay $D^0 \to \rho(770)^0\rho(770)^0$, we measure
a longitudinal polarization of $P_L = (71 \pm 4\pm 2)$%.


title: The pi-pi mass spectrum in Y(4260) -> pi-pi-J/psi

abstract:
  Three ways of fitting the pi-pi mass spectrum in Y(4260) decays are studied.
Data presented recently by Belle cannot be fitted by the pi-pi S-wave intensity
for elastic scattering. They can be fitted by adding a rather arbitrary
destructive interference with the sigma pole term. A better fit may be obtained
with the decay sequence Y -> pi-H, H -> pi-J/psi, where H is a JPC=1--
c-cbar-q-qbar state peaking at 4.0 GeV with a width ~280 MeV. A third
possibility, involving a triangle diagram due to Y(4260)-> DD_1(2420),
D_1->D*(2007)-pi, DD*->pi-J/psi fails to fit the data. The first and second
possibilities could be resolved by analysis of the Y(4260) Dalitz plot and
pi-J/psi mass projection, not presently publicly available.


title: Precision Electroweak Physics at the Tevatron

abstract:
  An overview of Tevatron electroweak measurements performed by the CDF and D0
experiments is presented. The current status and future prospects for high
precision measurements of electroweak parameters and detailed studies of boson
production are highlighted.


title:
Measuring the mass of a sterile neutrino with a very short baseline
  reactor experiment

abstract:
  An analysis of the world's neutrino oscillation data, including sterile
neutrinos, (M. Sorel, C. M. Conrad, and M. H. Shaevitz, Phys. Rev. D 70,
073004) found a peak in the allowed region at a mass-squared difference $\Delta
m^2 \cong 0.9$ eV$^2$. We trace its origin to harmonic oscillations in the
electron survival probability $P_{ee}$ as a function of L/E, the ratio of
baseline to neutrino energy, as measured in the near detector of the Bugey
experiment. We find a second occurrence for $\Delta m^2 \cong 1.9$ eV$^2$. We
point out that the phenomenon of harmonic oscillations of $P_{ee}$ as a
function of L/E, as seen in the Bugey experiment, can be used to measure the
mass-squared difference associated with a sterile neutrino in the range from a
fraction of an eV$^2$ to several eV$^2$ (compatible with that indicated by the
LSND experiment), as well as measure the amount of electron-sterile neutrino
mixing. We observe that the experiment is independent, to lowest order, of the
size of the reactor and suggest the possibility of a small reactor with a
detector sitting at a very short baseline.


title: Timelike Form Factor of the Kaon for |Q^2|=M^2(J/psi)

abstract:
  The timelike form factor of the charged kaon is evaluated at
|Q^2|=M^2(J/psi)=9.59 GeV^2 by relating it to B(J/psi->K+K-), B(J/psi->K_SK_L)
and B(J/psi->e+e-). The resulting value, |Q^2|F_K(9.59 GeV^2)=0.81+-0.18 GeV^2
is found to be in good agreement with |Q^2|F_K(13.5 GeV^2)=0.85+-0.05 GeV^2
obtained recently by the direct measurement of the reaction e+e--> K+K-.


title: Beyond the Standard Model Searches at the LHC

abstract:
  This report presents recent results from studies of Beyond the Standard Model
physics at the LHC. A focus is placed on heavy gauge bosons, electroweak
symmetry breaking and left-right symmetry.


title: Measurement of the charge asymmetry in semileptonic Bs decays

abstract:
  We have performed the first direct measurement of the time integrated flavor
untagged charge asymmetry in semileptonic Bs decays, Asl(unt), by comparing the
decay rate of Bs --> mu+ Ds- nu X, where Ds- --> phi pi- and phi --> K+K-, with
the charge-conjugate Bs-bar decay rate. This sample was selected from 1.3/fb of
data collected by the D0 experiment in RunII of the Fermilab Tevatron collider.
We obtain Asl(unt) = [1.23 +- 0.97(stat) +- 0.17(syst)]*10^-2. Assuming that
Delta(M_s)/Gamma_s >> 1 and Delta(Gamma_s)/(2 Gamma_s) < 1, this result can be
translated into a measurement on the CP-violating phase in Bs mixing:
Delta(Gamma_s)/Delta(M_s)*tan(phi_s) = [2.45 +- 1.93(stat) +-
0.35(syst)]*10^-2.


title: New results from KLOE

abstract:
  The most precise determination of Vus comes from semileptonic kaon decays. We
have measured with the KLOE detector at DAFNE, the Frascati phi-factory, all
the experimental inputs to Vus for both neutral and charged kaons. Using our
results we extract the value of Vus with ~0.9% fractional error, which is
dominated by the theoretical error on the form factor, f+(0). A new
determination of the ratio Vus/Vud is also presented, based on our precise
measurement of the absolute branching ratio for the decay K -> mu nu (gamma),
combined with lattice results for the ratio f_K/f_pi. New results on CPT
symmetry and quantum mechanics test have also been achieved, which are based on
the first measurement of the charged asymmetry for KS -> pi e nu decay and on
interferometry studies using the phi -> KL KS -> pi+ pi- pi+ pi-.


title: Hadronic Interaction Modelling in MINOS

abstract:
  The Main Injector Neutrino Oscillation search (MINOS) uses two detectors
separated by 735km to measure a beam of neutrinos created by the Neutrinos at
the Main Injector (NuMI) facility at Fermi National Accelerator Laboratory. The
experiment has recently reported an observation of muon-neutrino disappearance
consistent with neutrino oscillations. We describe the manner in which the
experiment's results depend on the correct understanding and modeling of
hadronic systems.


title: The Construction of the BESIII Experiment

abstract:
  BESIII is a high precision, general purpose detector for the high luminosity
$e^+e^-$ collider, BEPCII, running at the tau-charm energy region. Its design
and current status of construction is presented.


title: Pentaquark Searches in H1

abstract:
  We report on searches in deep inelastic $ep$ scattering for narrow baryonic
states decaying into $\Xi^-\pi^-, \Xi^-\pi^+, \KS p$ and their charge
conjugates, at centre-of-mass energies of 300 and 318 GeV. No signal for a new
narrow baryonic state is observed in the mass ranges 1600-2100 MeV ($\Xi\pi$)
and from threshold up to 1700 MeV ($\KS p$). The standard baryon $\Xi(1530)^0$
is observed in the decay mode $\Xi^-\pi^+$, and mass dependent upper limits on
the ratio of the hypothetical pentaquark states $\Xi^{--}_{5q}$ and
$\Xi^0_{5q}$ to the $\Xi(1530)^0$ signal are given. Also for the hypothetical
strange pentaquark $\Theta^+$ mass dependent upper limits on $\sigma(ep\to
e\Theta^+X)\times
  BR(\Theta^+\to K^0p)$ are obtained. Finally measurements of the acceptance
corrected ratios $\sigma(D^{\ast}p(3100))/\sigma(D^{\ast})$ for the
electroproduction of the anti-charmed baryon state $D^{\ast}p(3100)$ decaying
into $D^{\ast}$ and $p$ are presented.

abstract:
  From an analysis of the decay Bs -> J/psi phi we obtain the width difference
between the light and heavy mass eigenstates, and the CP-violating phase.


title: Lateral Distribution for Aligned Events in Muon Groups Deep Underground

abstract:
  The paper concerns the so-called aligned events observed in cosmic rays. The
phenomenon of the alignment of the most energetic subcores of gamma-ray--hadron
($\gamma-h$) families (particles of the highest energies in the central EAS
core) was firstly found in the "Pamir" emulsion chamber experiment and related
to a coplanar particle production at $E_0>10^{16}$ eV. Here a separation
distribution (distances between pairs of muons) for aligned events has been
analyzed throughout muon groups measured by Baksan Underground Scintillation
Telescope (BUST) for threshold energies $0.85 \div 3.2$ TeV during a period of
7.7 years. Only muon groups of multiplicity $m\geq 4$ with inclined
trajectories for an interval of zenith angles $50^\circ - 60^\circ$ were
selected for the analysis. The analysis has revealed that the distribution
complies with the exponential law. Meanwhile the distributions become steeper
with the increase of threshold energy. There has been no difference between the
lateral distribution of all the groups and the distribution of the aligned
groups.


title:
Spin asymmetry A_1^d and the spin-dependent structure function g_1^d of
  the deuteron at low values of x and Q^2

abstract:
  We present a precise measurement of the deuteron longitudinal spin asymmetry
A_1^d and of the deuteron spin-dependent structure function g_1^d at Q^2 < 1
GeV^2 and 4*10^-5 < x < 2.5*10^-2 based on the data collected by the COMPASS
experiment at CERN during the years 2002 and 2003. The statistical precision is
tenfold better than that of the previous measurement in this region. The
measured A_1^d and g_1^d are found to be consistent with zero in the whole
range of x.


title:
Measurement of CP Asymmetry in a Time-Dependent Dalitz Analysis of B^0
  \to (\rho \pi)^0 and a Constraint on the Quark Mixing Matrix Angle \phi_2

abstract:
  We present a measurement of CP asymmetry using a time-dependent Dalitz plot
analysis of B0 --> pi+pi-pi0 decays based on a 414/fb data sample containing
449M BB pairs. The data was collected on the $\Upsilon$(4S) resonance with the
Belle detector at the KEKB asymmetric energy e+e- collider. Combining our
analysis with information on charged B decay modes, we perform a full Dalitz
and isospin analysis and obtain a constraint on the CKM angle $\phi_2$, 68 deg.
< $\phi_2$ < 95 deg. as the 68.3% confidence interval for the $\phi_2$ solution
consistent with the standard model (SM). A large SM-disfavored region also
remains.


title: A Precision Determination of the D^0 Mass

abstract:
  A precision measurement of the D^0 meson mass has been made using ~281 pb-1
of e+e- annihilation data taken with the CLEO-c detector at the psi(3770)
resonance. The exclusive decay D^0 -> (Ks phi) has been used to obtain
M(D^0)=1864.847+-0.150(stat)+-0.095(syst) MeV. This corresponds to M(D^0
D^*0)=3871.81+-0.36 MeV, and leads to a well-constrained determination of the
binding energy of the proposed (D^0 D^*0) molecule X(3872), E_b=0.6+-0.6 MeV.


title: Neutrino Oscillation Search at MiniBooNE

abstract:
  This article reports the status of a $\nu_{\mu} \to \nu_{e}$ oscillation
search in MiniBooNE (Booster Neutrino Experiment) experiment. If an appearance
signal is observed, it will imply Physics Beyond the Standard Model such as the
existence of light sterile neutrino.


title: Charm Leptonic and Semileptonic Decays

abstract:
  Experimental results for the pseudoscalar decay constants f_{D} and f_{D_s}
are reviewed. Semileptonic form factor results from D -> (pseudoscalar) l nu
and D -> (vector) l nu decays are also reviewed.


title: Status and Commissioning of the CMS Experiment

abstract:
  After a brief overview of the Compact Muon Solenoid (CMS) experiment, the
status of construction and installation is described in the first part of the
note. The second part of the document is devoted to a discussion of the general
commissioning strategy of the CMS experiment, with a particular emphasis on
trigger, calibration and alignment. Aspects of b-physics, as well as examples
for early physics with CMS are also presented. CMS will be ready for data
taking in time for the first collisions in the Large Hadron Collider (LHC) at
CERN in late 2007.


title: Neutrino Oscillations with Reactor Neutrinos

abstract:
  Prospect measurements of neutrino oscillations with reactor neutrinos are
reviewed in this document. The following items are described: neutrinos
oscillations status, reactor neutrino experimental strategy, impact of
uncertainties on the neutrino oscillation sensitivity and, finally, the
experiments in the field. This is the synthesis of the talk delivered during
the NOW2006 conference at Otranto (Italy) during September 2006.


title: Measurement of the Omega_c^0 lifetime

abstract:
  We report a precise measurement of the Omega_c^0 lifetime. The data were
taken by the SELEX (E781) experiment using 600 GeV/c Sigma-, pi- and p beams.
The measurement has been made using 83+/-19 reconstructed Omega_c^0 in the
Omega- pi- pi+ pi+ and Omega- pi+ decay modes. The lifetime of the Omega_c^0 is
measured to be 65 +/- 13(stat) +/- 9(sys) fs.


title: Flavor Tagging at Tevatron incl. calibration and control

abstract:
  This report summarizes the flavor tagging techniques developed at the CDF and
D{\O}experiments. Flavor tagging involves identification of the B meson flavor
atproduction, whether its constituent is a quark or an anti-quark. It is
crucial for measuring the oscillation frequency of neutral B mesons, both in
the B^0 and B_S system. The two experiments have developed their unique
approaches to flavor tagging, using neural networks, and likelihood methods to
disentangle tracks from $b$ decays from other tracks. This report discusses
these techniques and the measurement of B^0 mixing, as a means to calibrate the
taggers.


title: Production of D* Mesons with Dijets in Deep-Inelastic Scattering at HERA

abstract:
  Inclusive D* production is measured in deep-inelastic ep scattering at HERA
with the H1 detector. In addition, the production of dijets in events with a D*
meson is investigated. The analysis covers values of photon virtuality 2< Q^2
<=100 GeV^2 and of inelasticity 0.05<= y <= 0.7. Differential cross sections
are measured as a function of Q^2 and x and of various D* meson and jet
observables. Within the experimental and theoretical uncertainties all measured
cross sections are found to be adequately described by next-to-leading order
(NLO) QCD calculations, based on the photon-gluon fusion process and DGLAP
evolution, without the need for an additional resolved component of the photon
beyond what is included at NLO. A reasonable description of the data is also
achieved by a prediction based on the CCFM evolution of partons involving the
k_T-unintegrated gluon distribution of the proton.


title: Rare K Decays

abstract: Recent results on rare K decays from KTeV and NA48 are reviewed.


title: Cavity Microwave Searches for Cosmological Axions

abstract:
  This chapter will cover the search for dark matter axions based on microwave
cavity experiments proposed by Pierre Sikivie. The topic begins with a brief
overview of halo dark matter and the axion as a candidate. The principle of
resonant conversion of axions in an external magnetic field will be described
as well as practical considerations in optimizing the experiment as a
signal-to-noise problem. A major focus of the lecture will be the two
complementary strategies for ultra-low noise detection of the microwave photons
- the ``photon-as-wave'' approach (i.e. conventional heterojunction amplifiers
and soon to be quantum-limited SQUID devices), and ``photon-as-particle'' (i.e.
Rydberg-atom single-quantum detection). Experimental results will be presented;
these experiments have already reached well into the range of sensitivity to
exclude plausible axion models, for limited ranges of mass. The section will
conclude with a discussion of future plans and challenges for the microwave
cavity experiment.

CP Violation and K0 decays revelation: study and simulation of neutral
  Trigger in NA48 experiment -- Violazione di CP e rivelazione dei decadimenti
  del K0: studio e simulazione del Trigger neutro nell'esperimento NA48

abstract:
  At the INFN laboratory in Pisa I have prepared my dissertation, which
essentially concerned Montecarlo simulation of subnuclear particles decays and
investigation of low-noise electronic devices for analyzing high-frequency
signals. The team-work was part of NA48/EPSI experiment jointly carried out
with European Organization for Nuclear Research CERN, Geneva.
  -----
  Nell'ambito dell'esperimento NA48 in corso al CERN Super Proton Syncrothon
(SPS) finalizzato a misurare la violazione diretta di CP in sistemi di
particelle K0 attraverso il doppio rapporto R =
[N(K_L->Pi0Pi0)]/[N(K_S->Pi0Pi0)] / [N(K_L->Pi+Pi-)]/[N(K_S->Pi+Pi-)] = 1 - 6
Re(e1/e) con una precisione di Re(e1/e) superiore a 2 * 10^-4, il lavoro di
tesi si propone di effettuare una simulazione per la rivelazione dei
decadimenti neutri dei K0 ed una successiva analisi dei dati raffrontando
l'evento fisico generato con metodo Montecarlo e quello ricostruito. Per la
misura di e1/e occorre isolare tra i vari modi di decadimento dei K quelli
K_S->Pi0Pi0, K_S->Pi+Pi-, e quelli K_L->Pi0Pi0, K_L->Pi+Pi-.


title: Charm and beauty structure of the proton

abstract:
  This paper will review the data collected by the H1 and ZEUS Collaborations
concerning the production of heavy quarks (charm and beauty) at the
electron-proton collider HERA. Heavy quark production is an important testing
ground for quantum chromodynamics (QCD), because QCD calculations are expected
to be reliable if a hard scale is present in the process. In heavy quarks
production a hard scale is provided by the quark mass. Moreover heavy quarks
production can give direct access to the gluon density in the proton due to the
fact that it proceeds, in QCD, almost exclusively via photon-gluon fusion,
where a photon from the incoming electron interacts with a gluon in the proton
giving an heavy quark-anti-quark pair. Results will be shown both for
deep-inelastic scattering (DIS), where the virtuality of the exchanged boson
Q**2 is large, and photo-production, where the Q**2 is equal to zero. Various
experimental techniques are used in order to select charm and beauty events,
ranging from the measurement of D* cross section to impact parameter analyses.
The results are found to be compatible with the predictions of perturbative
QCD. A brief summary of the open charm analyses done by the COMPASS
Collaboration will be also given.


title: LHCb strategies for gamma from B to DK

abstract:
  One of the most promising ways to determine the angle gamma of the CKM
unitarity triangle is through measurement of the tree level processes B to DK.
The LHCb collaboration has studied the potential of these decays employing the
Atwood-Dunietz-Soni (ADS) and Dalitz methods, making use of a large sample of
simulated data. For each method the expected sensitivities to the angle gamma
are presented in this report.


title:
A Precision Measurement of the Neutrino Mixing Angle theta_13 using
  Reactor Antineutrinos at Daya Bay

abstract:
  A reactor-neutrino experiment, Daya Bay, has been proposed to determine the
least-known neutrino mixing angle theta_13 using electron antineutrinos
produced at the Daya Bay nuclear power complex in China. Daya Bay is an
international collaboration with institutions from China, the United States,
the Czech Republic, Hong Kong, Russia, and Taiwan. The experiment will use
eight identical detectors deployed at three different locations optimized for
monitoring the antineutrino rates from the six reactors and for detecting any
rate deficit and spectral distortion near the first oscillation maximum. The
overburden of the under ground experimental halls, connected with tunnels,
ranges from about 250 to 900 meters-water-equivalent so that the cosmogenic
background is small compared to the number of observed antineutrino events.
Civil construction of tunnels and experimental facilities is planned to start
in 2007, with detector construction beginning in 2008. The experiment will
begin collecting data in 2010. By comparing the detected signals at the three
locations, with three years of data, a sensitivity in sin**2(2theta_13) of
better than 0.01 is expected.


title: Top physics at the Tevatron Run 2

abstract:
  The $p\bar p$ collider Tevatron, with its high center of mass energy of 2 TeV
is presently the unique top quark factory in the world. Thousands of top-quarks
have been produced during Run IIa. This gives the opportunity to study the
production and the properties of the heaviest known fundamental particle. This
article will summarize a sample of recent top quark physics results obtained at
the Tevatron.


title: Measurement of alpha / phi_2 from B to pi pi decays

abstract:
  The current results on B to pipi decays and SU2 constraints on the Unitarity
Triangle angle alpha or phi_2 from the B-factories are summarised. Based on
these measurements, predictions of the isospin analysis constraints at the end
of the lifetime of both B-factories are given.


title: Charmless B Decays

abstract:
  We report several new and updated results from Belle and BABAR for rare
hadronic B decays. These include many new results for B decays to eta'X and
omegaX and new measurements of the longitudinal polarisation in the decays B ->
rho K*.


title: Prompt Photons and Particle Momentum Distributions at HERA

abstract:
  Recent results, obtained by the H1 and ZEUS collaborations, are presented on
differential cross sections, for inclusive prompt photon production in DIS and
for photoproduction of prompt photons accompanied by a hadronic jet. Also
presented are cross sections of normalised scaled momentum distribution of
charged final state hadrons, measured by H1 in DIS $ep$ collisions at high
$Q^2$ in the Breit frame of reference.

  The status of $B$ physics, CP violation and related measurements at the time
of the Beauty 2006 conference are summarized. Particular attention is given to
the exciting prospects that lie ahead, at the commencement of the LHC era, and
beyond.


title:
Measurement of the B+ --> rho+ pi0 Branching Fraction and Direct CP
  Asymmetry

abstract:
  We present improved measurements of the branching fraction and CP asymmetry
for the process B+ --> rho+ pi0. The data sample corresponding to 211/fb
comprises 232 million Y(4S)-->BBbar decays collected with the BABAR detector at
the PEP-II asymmetric B Factory at SLAC. The yield and CP asymmetry are
measured using an extended maximum likelihood fitting method. The branching
fraction and CP asymmetry are found to be BR(B+ --> rho+ pi0)= [10.2 +-
1.4(stat) +- 0.9(syst)] x 10^-6 and Acp (B+ --> rho+ pi0) = -0.01 +- 0.13(stat)
+- 0.02(syst).


title: Measurements of the Top Quark at the Tevatron Collider

abstract:
  We present recent preliminary measurements of the top-antitop pair production
cross section and determinations of the top quark pole mass, performed using
the data collected by the CDF and D0 Collaborations at the Tevatron Collider.
In the lepton plus jets final state, with semileptonic B decay, the pair
production cross section has now been measured at CDF using 760 pb^{-1} of
proton-antiproton collisions at a centre-of-mass energy of \sqrt{s}=1.96 TeV. A
measurement of the production cross section has also been made with 1 fb^{-1}
of data in the all-jets final state by the CDF Collaboration. The mass of the
top quark has now been measured using 1 fb^{-1} of collision data using all
decay channels of the top quark pair, yielding the most precise measurements of
the top mass to date.


title:
Jet properties from di-hadron correlations in p+p collisions at s**(1/2)
  = 200-GeV

abstract:
  An analysis of high pT hadron spectra associated with high pT $\pi^0$
particles in p+p collisions at s**(1/2) = 200-GeV is presented. The shape of
the azimuthal angular correlation is used to determine the value of partonic
intrinsic momentum $\sqrt{\left<k^2_T\right>} = 2.68 \pm 0.07(\rm stat) \pm
0.34(\rm sys)$ GeV/c. The effect of kT-smearing of inclusive $\pi^0$ cross
section is discussed.


title: WW and WZ Production at the Tevatron

abstract:
  This report summarizes recent measurements of the production properties of WW
and WZ pairs of bosons at the Tevatron. This includes measurements of the
cross-section and triple gauge couplings in the WW process and the first
evidence for WZ production.


title:
Jet-radius dependence of inclusive-jet cross sections in deep inelastic
  scattering at HERA

abstract:
  Differential inclusive-jet cross sections have been measured for different
jet radii in neutral current deep inelastic ep scattering for boson
virtualities Q^2 > 125 GeV^2 with the ZEUS detector at HERA using an integrated
luminosity of 81.7 pb^-1. Jets were identified in the Breit frame using the k_T
cluster algorithm in the longitudinally inclusive mode for different values of
the jet radius R. Differential cross sections are presented as functions of Q^2
and the jet transverse energy, E_T,B^jet. The dependence on R of the
inclusive-jet cross section has been measured for Q^2 > 125 and 500 GeV^2 and
found to be linear with R in the range studied. Next-to-leading-order QCD
calculations give a good description of the measurements for 0.5 <= R <= 1. A
value of alpha_s(M_Z) has been extracted from the measurements of the
inclusive-jet cross-section dsigma/dQ^2 with R=1 for Q^2 > 500 GeV^2:
alpha_s(M_Z) = 0.1207 +- 0.0014 (stat.) -0.0033 +0.0035 (exp.) -0.0023 +0.0022
(th.). The variation of alpha_s with E_T,B^jet is in good agreement with the
running of alpha_s as predicted by QCD.


title: The MiniBooNE Experiment : An Overview

abstract:
  Neutrino oscillations have been observed in three sectors : solar ($\nu_e$
disappearance), atmospheric ($\nu_{\mu}$ disappearance), and accelerator
($\bar{\nu_{\mu}} \to \bar{\nu_e}$). The probability for two-neutrino
oscillation is a function of four variables : two are determined by the
conditions of the experiment, and two are the quantities fit for when
performing an oscillation search ($\sin^2(2\theta)$ and $\Delta m^2$). $\Delta
\mathrm{m}^2$ is the difference in squares of the mass states of the neutrinos
($\Delta \mathrm{m}^2_{12}$ = $\mathrm{m}^2_2$ - $\mathrm{m}^2_1$). If the
observed oscillations only occur between neutrinos in the Standard Model a
summation law of the $\Delta \mathrm{m}^2$ is valid ($\Delta \mathrm{m}^2_{13}$
= $\Delta \mathrm{m}^2_{12}$ + $\Delta \mathrm{m}^2_{23}$). The observed
oscillations do not follow this summation law. This implies one of the results
is incorrect or there exists physics beyond the Standard Model. While the solar
and atmospheric results have been confirmed by several different experiments,
the accelerator based result, from the Los Alamos LSND experiment, has yet to
be fully vetted. The MiniBooNE experiment, located at Fermi National
Laboratory, is designed to fully explore the LSND result. MiniBooNE is in the
final stages of performing a blind oscillation search ($\nu_{\mu} \to \nu_e$)
using neutrino data collected through November, 2005. A blind analysis is one
in which you may analyze some of the information in all of the data, all of the
information in some of the data, but not all of the information in all of the
data. As MiniBooNE hasn't yet opened the box, this discussion will focus on the
different components of MiniBooNE relevant for the oscillation analysis.


title:
Production of Mesons and Baryons at High Rapidity and High Pt in
  Proton-Proton Collisions at sqrt(s) = 200 GeV

abstract:
  We present particle spectra for charged hadrons $\pi^\pm, K^\pm, p$ and
$\bar{p}$ from pp collisions at $\sqrt{s}=200$ GeV measured for the first time
at forward rapidities (2.95 and 3.3). The kinematics of these measurements are
skewed in a way that probes the small momentum fraction in one of the protons
and large fractions in the other.
  Large proton to pion ratios are observed at values of transverse momentum
that extend up to 4 GeV/c, where protons have momenta up to 35 GeV.
Next-to-leading order perturbative QCD calculations describe the production of
pions and kaons well at these rapidities, but fail to account for the large
proton yields and small $\bar{p}/p$ ratios.


title: Looking for Exotica at the B Factories

abstract:
  Current experiments at the B factories, designed to perform precision
measurements of matter-antimatter asymmetry in the B meson system, have a much
broader physics reach especially in the sector of quarkonium spectroscopy. Here
we present a minireview on the new charmonium-like states observed at the B
factories including the X(3872) and Y(4260).


title:
Tagged Neutron, Anti-neutron and K-Long beams in an Upgraded MIPP
  Spectrometer

abstract:
  The MIPP experiment operating with an upgraded data acquisition system will
be capable of acquiring data at the rate of 3000 events per second. Currently
we are limited to a rate of 30 Hz due to the bottlenecks in the data
acquisition electronics of the Time Projection Chamber (TPC). With the speeded
up DAQ, MIPP will be capable of acquiring data at the rate of $\approx$5
million events per day. This assumes a conservative beam duty cycle of 4~sec
spill every 2 minutes with a 42% downtime for main injector beam manipulations
for the $\bar{p}$ source. We show that such a setup is capable of producing
tagged neutron, anti-neutron and $K^0_L$ beams that are produced in the MIPP
cryogenic hydrogen target using proton, anti-proton and $K^{\pm}$ beams. These
tagged beams can be used to study calorimeter responses for use in studies
involving the Particle Flow Algorithm (PFA). The energy of these tagged beams
will be known to better than 2% on a particle by particle level by means of
constrained fitting. We expect a tagged beam rate in the tens of thousands a
day. The MIPP spectrometer thus offers a unique opportunity to study the
response of calorimeters to neutral particles.


title: Measurements of sin2Beta and cos2Beta from b --> ccbars decays at BaBar

abstract:
  Recent measurements of sin2Beta and cos2Beta using b --> ccbars decays are
presented using data collected by the BaBar experiment at the PEP-II
asymmetric-energy B-factory.


title:
Charge-Separated Atmospheric Neutrino-Induced Muons in the MINOS Far
  Detector

abstract:
  We found 140 neutrino-induced muons in 854.24 live days in the MINOS far
detector. We looked for evidence of neutrino disappearance in this data set by
computing the ratio of the number of low momentum muons to the sum of the
number of high momentum and unknown momentum muons for both data and Monte
Carlo expectation in the absence of neutrino oscillations. The ratio of data
and Monte Carlo ratios is consistent with an oscillation signal. A fit to the
data for the oscillation parameters excludes the null oscillation hypothesis at
the 94% confidence level. We separated the muons by charge sign in both the
data and Monte Carlo events and found the ratio of the total number of negative
to positive muons in both samples. The ratio of those ratios is a test of CPT
conservation. The result is consistent with CPT conservation.


title:
Search for B decays into eta' rho, eta' K*, eta' phi, eta' omega and
  eta' eta(') at Belle

abstract:
  We report on a search for the exclusive two-body charmless hadronic B meson
decays B-> eta' rho, B-> eta' K*, B-> eta' phi, B-> eta' omega and B->eta'
eta('). The results are obtained from a data sample containing 535 x 10^6 BBbar
pairs that were collected at the Upsilon(4S) resonance with the Belle detector
at the KEKB asymmetric-energy e+ e- collider. We find no significant signals
and report upper limits in the range 0.5-6.5 x 10^{-6} for all of the above
decays.


title:
Measurement of angle beta with time-dependent CP asymmetry in B0->K+K-K0
  decays

abstract:
  We present recent results on CP violation, and the determination of CKM angle
beta, with the decay B0->K+K-K0, with BABAR and Belle detectors.


title:
Double Longitudinal Spin Asymmetry in Neutral Pion Production in
  Polarized p+p Collisions at sqrt(s)=200 GeV at PHENIX

abstract:
  A major goal of the RHIC spin program is to measure \Delta g, the gluon
contribution to the proton's spin. Measurements by PHENIX of the double
longitudinal spin asymmetry, A_LL, of the neutral pion production at
mid-rapidity in polarized proton collisions have been shown to constrain \Delta
g. Results from the 2005 RHIC run, as well as high p_T data from the 2006 RHIC
run, are presented. The results disfavor maximal positive and negative values
of \Delta g. A measurement of azimuthally independent double transverse spin
asymmetry, A_TT, is also presented.


title: First MINOS Results with the NuMI Beam

abstract:
  The results from the initial exposure of the MINOS detectors to neutrinos
produced by the Fermilab NuMI beam are reported here. The exposure consisted of
1.27 x 10^{20} 120 GeV protons incident on the NuMI target. The data show the
observation of 215 neutrinos with energies below 30 GeV while 336 +/- 14.4
events were expected. The data are consistent with nu_mu disappearance via
neutrino oscillations.


title:
Events with Isolated Leptons and Missing Transverse Momentum in ep
  Collisions at HERA

abstract:
  The analysis of events with isolated leptons and missing transverse momentum
in the H1 experiment is discussed for the electron, muon and tau channels. In
the Standard Model (SM) framework, production of real W-bosons gives rise to
such topologies. Contributions to the background are dominated by QCD
processes. An excess of observed signal over background presents a chance of
the discovery of new physics. The results using the HERA 1994-2006 data set
corresponding to 341 pb^-1 are presented. While the e- p sample shows good
agreement between data and SM expectation, in e+ p collisions an excess over
the SM expectation with 3.4 sigma significance is observed at high hadronic
transverse momentum.


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

abstract:
  We report on measurements of the inclusive jet production cross section as a
function of the jet transverse momentum in pp-bar collisions at sqrt{s} = 1.96
TeV}, using the k_T algorithm and a data sample corresponding to 1.0 fb^-1
collected with the Collider Detector at Fermilab in Run II. The measurements
are carried out in five different jet rapidity regions with |yjet| < 2.1 and
transverse momentum in the range 54 < \ptjet < 700 GeV/c. Next-to-leading order
perturbative QCD predictions are in good agreement with the measured cross
sections.


title: $K\to 3 \pi$ decay results by NA48/2 at CERN SPS

abstract:
  The NA48/2 has collected the largest amount of $K\to3 \pi$. The charge
asymmetry parameter $A_g$, sensitive to CP violation effects, has been measured
with a precision of $10^{-4}$ (preliminary) both in the three charged pion mode
("charged" mode) and in the mode with two neutral pions in the final state
("neutral" mode). The Dalitz plot structure in the "neutral" mode will be
discussed to point out the effects of the charged pion rescattering. The new
preliminary measurement of the Dalitz plot parameters in the charged mode will
be presented


title: Measurement of the absolute branching fraction of the Ds+- meson

abstract:
  The Ds+- -> K+-K-+pi+- absolute branching fraction is measured using e+e- ->
Ds*+- Ds1-+(2536) events collected by the Belle detector at the KEKB e+e-
asymmetric energy collider. Using the ratio of yields when either the Ds1 or
Ds* is fully reconstructed, we find Br(Ds+- -> K+-K-+pi+-)=
(4.0+-0.4(stat)+-0.4(sys))%.


title: Searching for New Physics: Results from Belle and Babar

abstract:
  The $B$-factories provide rich opportunities to search for new phenomena, in
$B$, charm, and tau decays. Presented here is a selection of recent results
from Belle and Babar.


title: R-hadron at ATLAS -Discovery Prospects and Properties

abstract:
  R-hadrons are massive, meta-stable particles predicted in several Super-
symmetry scenarios. Studies exploring the discovery potential of R-hadrons at
the ATLAS detector have mainly focused on gluino R-hadrons. These studies have
shown that gluino R-hadrons should be discovered in early running of the LHC,
that they are easily isolated by simple cuts and that their mass can be
measured to an accuracy of a few percent.


title: First Observation of Bottom Baryon Sigma_b States at CDF

abstract:
  We present the latest results on the search of bottom baryon states
  Sigma_b using 1 fb^-1 of CDF data. The study is performed with the world's
largest sample of fully reconstructed Lambda_b decays collected by CDF II
detector at the collision energy of 1.96 TeV in the hadronic trigger path. We
observe 4 new states consistent with Sigma_b(*)+/- bottom baryons.


title: Measurement of charmless $B$ Decays to $\eta K^*$ and $\eta \rho$

abstract:
  We report measurements of branching fractions and CP asymmetries for $B \to
\eta K^*$ and $B \to \eta \rho$ decays. These results are obtained from a $414
{\rm fb}^{-1}$ data sample collected at the $\Upsilon(4S)$ resonance with the
Belle detector at the KEKB asymmetric-energy $e^+ e^-$ collider. We measure the
following branching fractions: ${\mathcal B}(B^0 \to \eta K^{*0}) = (15.2 \pm
1.2 \pm 1.0)\times 10^{-6}$ and ${\mathcal B}(B^+\to\eta K^{*+}) =
(19.3^{+2.0}_{-1.9}\pm 1.5)\times 10^{-6}$, where the first error is
statistical and the second systematic. We also find a $2.7\sigma$ excess in the
$B^+\to\eta \rho^+$ mode and measure $\mathcal B(B^+\to\eta \rho^+)=
(4.1^{+1.4}_{-1.3}\pm 0.4)\times 10^{-6} <6.5 \times 10^{-6}$ at 90% confidence
level. For $B^0 \to \eta \rho^0$ decays, we determine the upper limit $\mathcal
B(B^0\to\eta \rho^0) < 1.9 \times 10^{-6}$ at 90% confidence level. The partial
rate asymmetries are ${\mathcal A_{CP}}(\eta K^{*0}) = 0.17 \pm 0.08 \pm 0.01$,
${\mathcal A_{CP}}(\eta K^{*+}) = 0.03 \pm 0.10 \pm 0.01$, and ${\mathcal
A_{CP}}(\eta \rho^+) = -0.04^{+0.34}_{-0.32}\pm 0.01$.


title: First search for $K_{L}\to\pi^{0}\pi^{0}\nu\bar{\nu}$

abstract:
  The first search for the rare kaon decay $\kppnn$ has been performed by the
E391a collaboration at the KEK 12-GeV proton synchrotron. An upper limit of
$4.7\times10^{-5}$ at the 90 % confidence level was set for the branching ratio
of the decay $\kppnn$ using about 10 % of the data collected during the first
period of data taking. First limits for the decay mode $\kppP$, where $P$ is a
pseudoscalar particle, were also set.

the Xi_cc^++.


title: COMPASS Results on Transverse Single-Spin Asymmetries

abstract:
  New results on single spin asymmetries of charged hadrons produced in
deep-inelastic scattering of muons on a transversely polarised LiD target are
presented. The data were taken in the years 2002, 2003 and 2004 with the
COMPASS spectrometer using the muon beam of the CERN SPS at 160 GeV/c.
Preliminary results are given for the Sivers asymmetry and for all the three
``quark polarimeters'' presently used in COMPASS to measure the transversity
distributions. The Collins and the Sivers asymmetries for charged hadrons turn
out to be compatible with zero, within the small (~1%) statistical errors, at
variance with the results from HERMES on a transversely polarised proton
target. Similar results have been obtained for the two hadron asymmetries and
for the Lambda polarisation. First attempts to describe the Collins and the
Sivers asymmetries measured by COMPASS and HERMES allow to give a consistent
picture of these transverse spin effects.


title:
Search for the \theta_{13} Neutrino Mixing Angle Using Reactor
  Anti-Neutrinos

abstract:
  The measurement of the last undetermined neutrino mixing angle \theta_{13} is
the main goal of the future experimental research on neutrino oscillations. At
present, \theta_{13} is only known to be much smaller than the two other mixing
angles, \theta_{12} and \theta_{23}. The present bound, which is dominated by
the result of the CHOOZ reactor experiment, is \sin^{2}2\theta_{13}<0.08 (at 90
% confidence level). However, it is widely recognized that the potential of
reactor anti-neutrino disappearance experiments has not been fully exploited
yet. A rich experimental program is underway, which aims at exploring in the
near future up to \sin^{2}2\theta_{13}\lesssim0.01. The targeted sensitivity
requires a clear-cut strategy to reduce significantly both statistical and
systematical errors with respect to past reactor experiments. A key feature for
the success of all projects is the installation of one or more near identical
detectors. The experimental concept and the status of the upcoming or proposed
reactor experiments, and as well the prospects of the reactor-based search for
\theta_{13} are reviewed.


title: First determination of the electric charge of the top quark

abstract:
  In this thesis, the first determination of the electric charge of the top
quark is presented using 370pb-1 of data recorded by the D0 detector at the
Fermilab Tevatron accelerator. ttbar events are selected with one isolated
electron or muon and at least four jets out of which two are b-tagged by
reconstruction of a secondary decay vertex (SVT). The method is based on the
discrimination between b- and bbar-quark jets using a jet charge algorithm
applied to SVT-tagged jets. A method to calibrate the jet charge algorithm with
data is developed. A constrained kinematic fit is performed to associate the W
bosons to the correct b-quark jets in the event and extract the top quark
electric charge. The data is in good agreement with the Standard Model top
quark electric charge of 2e/3. The scenario where the selected sample is solely
composed of an exotic quark Q with charge 4e/3 is excluded at 92% confidence
level. Using a Bayesian approach, an upper limit on the fraction of exotic
quarks rho < 0.80 at 90% confidence level is obtained.


title:
Search for production of single top quarks via flavor-changing neutral
  currents at the Tevatron

abstract:
  We search for the production of single top quarks via flavor-changing neutral
current couplings of a gluon to the top quark and a charm (c) or up (u) quark.
We analyze 230 pb^{-1} of lepton+jets data from \ppbar collisions at a center
of mass energy of 1.96 TeV collected by the D0 detector at the Fermilab
Tevatron Collider. We observe no significant deviation from standard model
predictions, and hence set upper limits on anomalous coupling parameters
\kappa^c_g/\Lambda and \kappa^u_g/\Lambda, where the \kappa_g define the
strength of the tcg and tug couplings, and \Lambda defines the scale of new
physics. The limits at 95% C.L. are: \kappa^c_g/\Lambda < 0.15 TeV^{-1} and
\kappa^u_g/\Lambda < 0.037 TeV^{-1}.


title: An improved limit on the axion-photon coupling from the CAST experiment

abstract:
  We have searched for solar axions or similar particles that couple to two
photons by using the CERN Axion Solar Telescope (CAST) setup with improved
conditions in all detectors. From the absence of excess X-rays when the magnet
was pointing to the Sun, we set an upper limit on the axion-photon coupling of
8.8 x 10^{-11} GeV^{-1} at 95% CL for m_a <~ 0.02 eV. This result is the best
experimental limit over a broad range of axion masses and for m_a <~ 0.02 eV
also supersedes the previous limit derived from energy-loss arguments on
globular-cluster stars.


title: Single hadron transverse spin asymmetries from COMPASS

abstract:
  Transverse spin physics is an important part of the scientific programme of
the COMPASS experiment at CERN. The analysis of the data taken with the target
polarized orthogonally to the 160 GeV/c muon beam momentum has allowed to
measure for the first time the Collins and Sivers asymmetries of the deuteron.
Both for the positive and the negative hadrons produced in semi-inclusive DIS
the measured asymmetries are small and, within errors, compatible with zero.
New results for charged pions and kaons are presented here.


title: Recent CLEO-c Results

abstract:
  Recent CLEO-c results on open and closed charm physics at center of mass of
3773 MeV (psi(3770) resonance), 4170 MeV and 3686 MeV (psi(2s) peak) are
reviewed. Measurements of absolute hadronic branching ratios of D0, D+ and Ds
mesons as well as charmonium spectroscopy are discussed. An outlook and future
prospects for the experiment at CESR is also presented.


title: Improved measurement of CP-violating parameters in rho+rho- decays

abstract:
  We present a measurement of the CP-violating asymmetry in rho+rho- decays
using 535 million BBbar pairs collected with the Belle detector at the KEKB
e+e- collider. We measure CP-violating coefficients A = 0.16 +- 0.21(stat) +-
0.07 (syst) and S = 0.19 +- 0.30(stat) +- 0.07 (syst}. These values are used to
determine the unitarity triangle angle phi_2 using an isospin analysis; the
solution consistent with Standard Model lies in the range 53 < phi_2 < 114 deg.
at 90 C.L.


title: Measurement of CP Asymmetry in B0 to Ks pi0 pi0 Decays

abstract:
  We present a measurement of the time-dependent CP asymmetry for the neutral
B-meson decay into the CP = +1 final state Ks pi0 pi0, with Ks -> pi+ pi-. We
use a sample of approximately 227 million B-meson pairs recorded at the
Upsilon(4S) resonance with the BABAR detector at the PEP-II B-Factory at SLAC.
  From an unbinned maximum likelihood fit we extract the mixing-induced
CP-violation parameter S = 0.72 +/- 0.71 +/- 0.08 and the direct CP-violation
parameter C = 0.23 +/- 0.52 +/- 0.13, where the first uncertainty is
statistical and the second systematic.


title: Recent Results in Bottomonium Spectroscopy

abstract:
  We review recent results in the spectroscopy of the bottomonium system. Among
the recent measurements discussed are measurements of decays of all three
sub-open threshold triplet-S bottomonium resonances to all three lepton
flavors, and measurements of the rates and invariant mass distributions for
dipion transitions among the triplet-S bottomonium states. Results from CLEO,
Belle and BaBar are presented.


title: New charmonium-like states

abstract:
  In recent years the B-factories and other machines have found evidence for a
large number of new states with hidden charm: candidate h_c(1P), eta_c(2S), and
chi_{c2}(2P) states; the well-established X(3872); enhancements called X(3940),
Y(3940), and Y(4260); and a new structure at 4350 MeV. Various
conventional-charmonium and more exotic interpretations of these data have been
proposed. In this talk we review the current state of the experimental evidence
and the prospects for clarifying the spectrum.


title: Charmonium Physics with PANDA at FAIR

abstract:
  One component of the future international Facility for Antiproton and Ion
Research - FAIR is directed towards studies of hadronic matter at the
sub-nuclear level with beams of antiprotons. These studies focus on two key
aspects: confinement of quarks and the generation of the hadron masses. These
goals will be pursued by performing precision measurements of charged and
neutral decay products from antiproton-proton annihilation in the charmonium
mass region. In this report an overview of the charmonium issues relevant to
PANDA will be presented.

title:
Measurements of Charged Kaon Semileptonic Decay Branching Fractions K^+-
  -> pi^0 mu^+- nu and K+- -> pi^0 e^+- nu and Their Ratio

abstract:
  Measured ratios of decay rates for Ke3/K2\pi, K\mu3/K2\pi and K\mu3/Ke3 are
presented. These measurements are based on K^+- decays collected in a dedicated
run in 2003 by the NA48/2 experiment at CERN. The results obtained are
Ke3/K2\pi = 0.2470 +/- 0.0009 (stat) +/- 0.0004 (syst) and K\mu3/K2\pi = 0.1637
+/- 0.0006 (stat) +/- 0.0003 (syst). Using the PDG average for the K^+- ->
\pi^+-\pi^0 normalisation mode, both values are found to be larger than the
current values given by the Particle Data Book and lead to a larger magnitude
of the |V_{us}| CKM element than previously accepted. When combined with the
latest Particle Data Book value of |V_{ud}|, the result is in agreement with
unitarity of the CKM matrix. In addition, a new measured value of K\mu3/Ke3 =
0.663 +/- 0.003(stat) +/- 0.001(syst) is compared to the semi-empirical
predictions based on the latest form factor measurements.


title: A Flavor of KLOE

abstract:
  This paper is a simple, quick guide to KLOE, the flagship experiment of
INFN's \Phi factory DAFNE at Frascati. KLOE's design principles, properties,
its physics accomplishments and its impact on "flavor physics", are described
in terms comprehensible to non specialists.


title:
Searches for lepton flavor violating decays $\tau^\pm \to
  \ell^\pm\gamma$, $\tau^\pm \to \ell^\pm P^0$ (where $\ell^- = e^-, \mu^-$,
  and $P^0$ = $\pi^0, \eta, \eta^{\prime}$) at B-Factories: Status and
  Combinations

abstract:
  The present experimental status of searches for lepton flavor violating
decays of the $\tau$ lepton to a lighter mass lepton and a photon or a
pseudoscalar meson is presented. The results obtained are from $e^+e^-$
annihilation data collected at a center-of-mass energy near 10.58 GeV by the
\babar and the Belle detectors. In order to benefit from larger available
datasets, the first $\babar-$Belle combinations of upper limits on the
branching fractions of lepton flavor violating $\tau$-decays are obtained.


title:
Measurement of the top quark mass in the lepton+jets channel using the
  Ideogram Method

abstract:
  A measurement of the top quark mass using events with one charged lepton,
missing transverse energy, and jets in the final state, collected by the D0
detector from p-pbar collisions at sqrt{s} = 1.96 TeV at the Fermilab Tevatron
collider, is presented. A constrained fit is used to fully reconstruct the
kinematics of the events. For every event a top quark mass likelihood is
calculated taking into account all possible jet assignments and the probability
that an event is signal or background. Lifetime-based identification of b jets
is employed to enhance the separation between t-tbar signal and background from
other physics processes and to improve the assignment of the observed jets to
the quarks in the t-tbar hypothesis. We extract a multiplicative jet energy
scale factor JES in-situ, greatly reducing the systematic effect related to the
jet energy measurement. In a data sample with an integrated luminosity of 425
pb-1, we observe 230 candidate events, with an estimated background of 123
events, and measure m_t = 173.7 +-4.4 (stat + JES) +2.1/-2.0 (syst) GeV. This
result represents the first application of the Ideogram technique to the
measurement of the top quark mass in lepton+jets events.


title: New Results on Xi0 Hyperon Decays

abstract:
  In the recent years many new measurements of the decay of the neutral Xi0
hyperon have been reported both by the NA48/1 and the KTeV collaboration. The
results are based on data samples of more than 2 billion Xi0 decays. In this
report new measurements of the Xi0 lifetime, decay asymmetries, and
semileptonic decay rates are presented. The latter allow the extraction of the
CKM matrix element |V_us|, complementary to kaon decays.


title: SUSY Multilepton Signatures at Tevatron

abstract:
  One of the most striking signature of supersymmetric models with electroweak
symmetry breaking is the presence of multilepton event topologies in the decay
products. In this paper searches are presented for physics beyond the Standard
Model (SM) in final states containing charged leptons from proton-antiproton
collision data at a center-of-mass energy of 1.96 TeV, collected with Run II
CDF and D{\O}Detectors in 2002-2006, and corresponding to integrated
luminosities of up to 1.1 fb$^{-1}$. In any of the searches no excess of
candidates was observed with respect to the SM predictions and limits on masses
and production cross-sections are set at the 95 % CL.


title: Hadronic D Decays and Dalitz Analyses

abstract:
  I review recent measurements of the branching fractions of hadronic D^0, D^+,
and D_s decays and Dalitz analyses of these and other hadronic D decay modes.


title: Semileptonic b to u transition

abstract:
  Experimental studies of charmless semileptonic B decays can be broadly
categorized into inclusive and exclusive measurements depending on how the
final states are treated. The inclusive method measures the decay rate
$\Gamma(B \to X_u \ell \nu)$, where $X_u$ is known as the hadronic system that
does not contain charm-quark. On the other hand, the exclusive method measures
the decay rates for exclusive final states such as $B \to \pi \ell \nu$ and
$\rho \ell \nu$. Two methods give not only different efficiencies and
signal-to-background ratios, but also different theoretical calculations to be
used in order to extract $|V_{ub}|$. Using both approaches and comparing the
results will help us verify the robustness of the theoretical error estimation,
which dominates the current uncertainty in the determination of $|V_{ub}|$.
Progress in last few years will be summarized in this presentation.


title:
Production and Detection of Axion-Like Particles in a HERA Dipole Magnet
  - Letter-of-Intent for the ALPS experiment -

abstract:
  Recently, the PVLAS collaboration has reported evidence for an anomalous
rotation of the polarization of light in vacuum in the presence of a transverse
magnetic field. This may be explained through the production of a new light
spin-zero (axion-like) neutral particle coupled to two photons. In this
letter-of-intent, we propose to test this hypothesis by setting up a photon
regeneration experiment which exploits the photon beam of a high-power infrared
laser, sent along the transverse magnetic field of a superconducting HERA
dipole magnet. The proposed ALPS (Axion-Like Particle Search) experiment offers
a window of opportunity for a rapid firm establishment or exclusion of the
axion-like particle interpretation of the anomaly published by PVALS. It will
also allow for the measurement of mass, parity, and coupling strength of this
particle. [The experiment has been approved by the DESY directorate on January
11, 2007.]


title:
Measurement of the production cross-section of positive pions in the
  collision of 8.9 GeV/c protons on beryllium

abstract:
  The double-differential production cross-section of positive pions,
$d^2\sigma^{\pi^{+}}/dpd\Omega$, measured in the HARP experiment is presented.
The incident particles are 8.9 GeV/c protons directed onto a beryllium target
with a nominal thickness of 5% of a nuclear interaction length. The measured
cross-section has a direct impact on the prediction of neutrino fluxes for the
MiniBooNE and SciBooNE experiments at Fermilab. After cuts, 13 million protons
on target produced about 96,000 reconstructed secondary tracks which were used
in this analysis. Cross-section results are presented in the kinematic range
0.75 GeV/c < $p_{\pi}$ < 6.5 GeV/c and 30 mrad < $\theta_{\pi}$ < 210 mrad in
the laboratory frame.


title:
Measurement of the shape of the boson rapidity distribution for
  p\bar{p}-> Z/gamma*-> e+e- +X events produced at sqrt(s) of 1.96 TeV

abstract:
  We present a measurement of the shape of the boson rapidity distribution for
p\bar{p}-> Z/gamma*-> e+e- +X events at a center-of-mass energy of 1.96 TeV.
The measurement is made for events with electron-positron mass 71< M_ee < 111
GeV and uses 0.4 fb^-1 of data collected at the Fermilab Tevatron collider with
the D0 detector. This measurement significantly reduces the uncertainties on
the rapidity distribution in the forward region compared with previous
measurements. Predictions of NNLO QCD are found to agree well with the data
over the full rapidity range.


title: Charting the Course for Elementary Particle Physics

abstract:
  It was the best of times; it was the worst of times is the way Dickens begins
the Tale of Two Cities. The line is appropriate to our time in particle
physics. It is the best of times because we are in the midst of a revolution in
understanding, the third to occur during my career. It is the worst of times
because accelerator facilities are shutting down before new ones are opening,
restricting the opportunity for experiments, and because of great uncertainty
about future funding. My task today is to give you a view of the most important
opportunities for our field under a scenario that is constrained by a tight
budget. It is a time when we cannot afford the merely good, but must give first
priority to the really important.


title: Observation of WZ Production

abstract:
  We report the first observation of the associated production of a W boson and
a Z boson. This result is based on 1.1 fb-1 of integrated luminosity from ppbar
collisions at sqrt{s} = 1.96 TeV collected with the CDF II detector at the
Fermilab Tevatron. We observe 16 WZ candidates passing our event selection with
an expected background of 2.7 +/- 0.4 events. A fit to the missing transverse
energy distribution indicates an excess of events compared to the background
expectation corresponding to a significance equivalent to six standard
deviations. The measured cross section is sigma(ppbar -> WZ) =
5.0^{+1.8}_{-1.6} pb, consistent with the standard model expectation.


title:
Leading neutron energy and pT distributions in deep inelastic scattering
  and photoproduction at HERA

abstract:
  The production of energetic neutrons in $ep$ collisions has been studied with
the ZEUS detector at HERA. The neutron energy and $p_T^2$ distributions were
measured with a forward neutron calorimeter and tracker in a $40 \pb^{-1}$
sample of inclusive deep inelastic scattering (DIS) data and a $6 \pb^{-1}$
sample of photoproduction data. The neutron yield in photoproduction is
suppressed relative to DIS for the lower neutron energies and the neutrons have
a steeper $p_T^2$ distribution, consistent with the expectation from absorption
models. The distributions are compared to HERA measurements of leading protons.
The neutron energy and transverse-momentum distributions in DIS are compared to
Monte Carlo simulations and to the predictions of particle exchange models.
Models of pion exchange incorporating absorption and additional secondary meson
exchanges give a good description of the data.


title:
Search for New Physics in Lepton + Photon + X Events with 929 pb-1 of
  ppbar Collisions at roots = 1.96 TeV

abstract:
  We present results of a search at CDF in 929 pb-1 of ppbar collisions at 1.96
TeV for the anomalous production of events containing a high-transverse
momentum charged lepton (either electron or muon) and photon, accompanied by
missing transverse energy (MET), and/or additional leptons and photons, and
jets (X). We use the same selection criteria as in a previous CDF Run I search,
but with an order-magnitude larger data set, a higher ppbar collision energy,
and the CDF II detector. We find 163 Lepton + Photon + MET + X events, compared
to an expectation of 150.6+-13.0 events. We observe 74 Multi-Lepton + Photon +
X events, compared to an expectation of 65.1+-7.7 events. We find no events
similar to the Run I 2 electrons + 2 photons + MET event.


title:
Combined D0 Measurements Constraining the CP-violating Phase and Width
  Difference in the $B_s^0$ System

abstract:
  We combine the D0 measurement of the width difference between the light and
heavy B_s^0 mass eigenstates and of the CP-violating mixing phase determined
from the time-dependent angular distributions in the B_s -> J/psi phi decays
along with the charge asymmetry in semileptonic decays also measured with the
D0 detector. With the additional constraint from the world average of the
flavor-specific B_s^0 lifetime, we obtain Delta Gamma_s = (\Gamma_L - \Gamma_H)
= 0.13 +- 0.09 ps$^{-1}$ and phi_s = -0.70 ^{+0.47}_{-0.39}. The data sample
corresponds to an integrated luminosity of 1.1 fb^{-1} accumulated with the D0
detector at the Fermilab Tevatron Collider.


title: Evidence for CP Violation in B0 -> D+D- Decays

abstract:
  We report measurements of the branching fraction and CP violation parameters
in B0 -> D+D- decays. The results are based on a data sample that contains 535
x 10^6 BBbar pairs collected at the Upsilon(4S) resonance, with the Belle
detector at the KEKB asymmetric-energy e+e- collider. We obtain [1.97 +- 0.20
(stat) +- 0.20 (syst)] x 10^(-4) for the branching fraction of B0 -> D+D-. The
measured values of the CP violation parameters are: S = -1.13 +- 0.37 +- 0.09,
A = 0.91 +- 0.23 +- 0.06, where the first error is statistical and the second
is systematic. We find evidence of CP violation in B0 -> D+D- at the 4.1 sigma
confidence level. While the value of S is consistent with expectations from
other measurements, the value of the parameter A favors large direct CP
violation at the 3.2 sigma confidence level, in contradiction to Standard Model
expectations.


title: Recent Results from HERA

abstract:
  HERA is taking data since 1992; after a shutdown in 2000, data taking has
restarted in 2002 with a five-fold increase in the luminosity. The first
running period is referred to as HERA-I, whereas the second one is referred to
as HERA-II. In this report I will review some recent results obtained by the H1
and ZEUS experiments at the HERA collider.


title: Multi-lepton events at HERA

abstract:
  Events containing high-$P_T$ multi-leptons were sought at HERA by the H1 and
ZEUS collaborations. Experimental data were compared to simulations of $\gamma
\gamma \to l^+ l^-$ processes, and H1 extracted the total and differential
cross sections of the processes.
  The doubly-charged Higgs, which decays into lepton pairs, was analysed by H1
as a possible source of the multi-electron events, which have been observed at
high invariant masses.


title: Measurement of D*+- meson production in ep scattering at low Q^2

abstract:
  The production of D*+-(2010) mesons in ep scattering in the range of
exchanged photon virtuality 0.05 < Q^2 < 0.7 GeV^2 has been measured with the
ZEUS detector at HERA using an integrated luminosity of 82 pb-1. The decay
channels D*+ -> D0 pi+ with D0 -> K- pi+ and corresponding antiparticle decay
were used to identify D* mesons and the ZEUS beampipe calorimeter was used to
identify the scattered electron. Differential D* cross sections as functions of
Q^2, inelasticity, y, transverse momentum of the D* meson, p_T(D*), and
pseudorapidity of the D* meson, eta(D*), have been measured in the kinematic
region 0.02 < y < 0.85, 1.5 < p_T(D*) < 9.0 GeV and |eta(D*)| < 1.5. The
measured differential cross sections are in agreement with two different NLO
QCD calculations. The cross sections are also compared to previous ZEUS
measurements in the photoproduction and DIS regimes.


title: Leptonic and Semileptonic Charm Decays from CLEO-c

abstract:
  I describe CLEO-c purely leptonic decay results leading to fD+=(222.6 +/-
16.7^{+2.8}_{-3.4}) MeV, fDs+=(280.1 +/- 11.6 +/- 6.0) MeV, and fDs+/fD+=1.26
+/- 0.11 +/-0.03. Form-factor measurements in Cabibbo favored and suppressed
pseudoscalar decays are presented. Some comparisons are made with theoretical
predictions.


title: Exclusive Semileptonic b->u l nu Decays at CLEO

abstract:
  Updated CLEO results are presented for branching ratios and four-momentum
transfer q^2 dependence of exclusive charmless semileptonic B decays, where the
final state hadron is either a pi, rho, omega, eta or eta'. These results have
comparable accuracies with those of other experiments. We address the issue of
flavor singlet couplings by limiting Gamma(B+ -> eta' l+ nu)/\Gamma(B+ -> eta
l+ nu)> 2.5 at 90 % CL}. We also extract a value of |V_{ub}|= (4.3 +/- 0.4
+/-0.2^{+0.6}_{-0.4})x10^{-3} in one particular unquenched lattice QCD model
using pi l+nu data above q^2 of 16 GeV^2.


title:
First Measurement of the Ratio of Central-Electron to Forward-Electron W
  Partial Cross Sections in p-pbar Collisions at sqrt{s} = 1.96 TeV

abstract:
  We present a measurement of sigma(p-pbar -> W) x B(W->enu) at sqrt{s}=1.96
TeV, using electrons identified in the forward region (1.2 <|eta|<2.8) of the
CDF II detector in 223 pb-1 of data. We measure sigma x B = 2796
+-13(stat)+95-90(syst)+-162(lum)pb. Combining this result with a previous CDF
measurement obtained using electrons in the central region (|eta|<1), we
present the first measurement of the ratio of central-electron to
forward-electron W partial cross sections
R_exp=0.925+-0.006(stat)+-0.032(syst), consistent with theoretical predictions
using Coordinated Theoretical-Experimental Preoject on QCD (CTEQ) and
Martin-Roberts-Stirling-Thorne (MRST) parton distribution functions.


title:
Measurement of sin2beta in tree-dominated B0-decays and ambiguity
  removal

abstract:
  The most recent results from the B-factories on the time-dependent CP
asymmetries measured in B0-decays mediated by b --> c c(bar) s
quark-transitions are reviewed. The Standard Model interpretation of the
results in terms of the parameter sin2beta leads to a four-fold ambiguity on
the unitarity triangle beta which can be reduced to a two-fold ambiguity by
measuring the sign of the parameter cos2beta. The results on cos2beta obtained
so far are reviewed.


title: Measurements of the Decay $K_L \to e^+e^-\gamma$

abstract:
  The E799-II (KTeV) experiment at Fermilab has collected 83262 $K_L \to
e^+e^-\gamma$ events above a background of 79 events. We measure a decay width,
normalized to the $K_L \to \pi^0\pi^0\pi^0_D$ (\pi^0 \to \gamma\gamma, \pi^0 to
\gamma\gamma, \pi^0_D \to e^+e^-\gamma) decay width, of $\Gamma($K_L \to
e^+e^-\gamma$)/\Gamma(K_L \to \pi^0\pi^0\pi^0_D) = (1.3302 \pm 0.0046_{stat}
\pm 0.0102_{syst}) \times 10^{-3}$. We also measure parameters of two $K_L
\gamma^{\ast}\gamma$ form factor models. In the Bergstrom, Masso, and Singer
(BMS) parametrization, we find $\caks = -0.517 \pm 0.030_{stat} \pm
0.022_{syst}$. We separately fit for the first parameter of the D'Ambrosio,
Isidori, and Portoles (DIP) model and find $\adip = -1.729 \pm 0.043_{stat} \pm
0.028_{syst}$.


title: Searches for CP, T and CPT violation in B0B0bar mixing at BaBar

abstract:
  We describe measurements of CP and CPT violation parameters in B^0B^0bar
oscillations, performed at BaBar by using BBbar events collected at the Y(4S)
mass peak. These are obtained from two different B-reconstruction methods,
namely: searching for two inclusive semileptonic B^0 decays in an event or
partially reconstructing one of the B^0 mesons in the D* l nu_l channel. The
results are in agreement with one another and with the most recent theoretical
calculations in the Standard Model scenario.


title:
Determining the inelastic proton-proton cross section at the Large
  Hadron Collider using minimum bias events

abstract:
  Described in this paper is a new method for determining the non-diffractive
part of the inelastic proton-proton cross section, at the LHC centre of mass
energy of 14TeV. The method is based on counting the number of inelastic
proton-proton interactions in the collision regions. According to preliminary
investigation, this measurement will be best suited for the initial low
luminosity phase of the LHC. The dominant uncertainty on this measurement comes
from knowledge of the proton-proton luminosity.


title: Looking for single top quarks in D0 data

abstract:
  The search for the electroweak production of top quarks is entering an
exciting time: with the ever increasing luminosity furnished by the Tevatron
ppbar Collider at Fermilab and sophisticated analysis techniques we are now
able to approach the expected standard model production cross section for this
new mode of production. Using 370pb-1 of D0 data and likelihoods as
discriminants to extract the signal from the large backgrounds, we set upper
limits on the standard model production cross section in the s-channel of 5.0
pb and in the t-channel of 4.4 pb, at 95% confidence level.


title:
Observation of $B^+\to\rho^+K^0$ and Measurement of its Branching
  Fraction and Charge Asymmetry

abstract:
  We present the first observation of the decay $B^+\to\rho^+K^0$, using a data
sample of 348 fb$^{-1}$ collected at the $\Upsilon(4S)$ resonance with the
\babar detector.The branching fraction and charge asymmetry are measured to be
$(8.0^{+1.4}_{-1.3}\pm0.6)\times10^{-6}$ and ($-12.2\pm16.6\pm2.0)%$,
respectively, where the first uncertainty is statistical and the second is
systematic. The significance of the observed branching fraction, including
systematic uncertainties, is 7.9 standard deviations.


title:
Observation of a resonance in the K$_s$p decay channel at a mass of 1765
  MeV/c$^2$

abstract:
  We report on the observation of a K$_s$p resonance signal at a mass of
1765$\pm$5 MeV/c$^2$, with intrinsic width $\Gamma = 108\pm 22$ MeV/c$^2$,
produced inclusively in $\Sigma^-$-nucleus interactions at 340 GeV/c in the
hyperon beam experiment WA89 at CERN. The signal was observed in the kinematic
region $x_F>0.7$, in this region its production cross section rises
approximately linearly with $(1-x_F)$, reaching $BR(X\to K_S p)\cdot d\sigma
/dx_F = (5.2\pm 2.3) \mu b $ per nucleon at $x_F=0.8$. The hard \xf spectrum
suggests the presence of a strong leading particle effect in the production and
hence the identification as a $\Sigma^{*+}$ state. No corresponding peaks were
observed in the $K^- p$ and $\Lambda \pi^{\pm}$ mass spectra.


title:
Measurement of the Dalitz plot slope parameters of the
  $K^\pm\to\pi^\pm\pi^+\pi^-$ decay

abstract:
  The distribution of the $K^\pm\to\pi^\pm\pi^+\pi^-$ decays in the Dalitz plot
has been measured by the NA48/2 experiment at the CERN SPS with a sample of
$4.71\times 10^8$ fully reconstructed events. With the standard Particle Data
Group parameterization the following values of the slope parameters were
obtained: $g=(-21.134\pm0.017)\%$, $h=(1.848\pm0.040)\%$,
$k=(-0.463\pm0.014)\%$. The quality and statistical accuracy of the data have
allowed an improvement in precision by more than an order of magnitude, and are
such as to warrant a more elaborate theoretical treatment, including pion-pion
rescattering, which is in preparation.


title: Measurement of CP Asymmetries in B0 --> K0S K0S K0S Decays

abstract:
  We present measurements of the time-dependent CP-violating asymmetries in B0
--> K0S K0S K0S decays based on 384 million Y(4S) decays collected with the
BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. We obtain the
CP asymmetry parameters C = 0.02 +/- 0.21 +/- 0.05 and S = -0.71 +/- 0.24 +/-
0.04, where the first uncertainties are statistical and the second systematic.
These results are consistent with standard model expectations.


title: Spectroscopy and Decay of B Hadrons at the Tevatron

abstract:
  This paper reviews the spectroscopy and decay of B hadrons at the Tevatron.
We discuss the spectroscopy of excited B states (B**, Bs**) and the observation
of the Sigma_b baryon at the Tevatron. The second part of this review discusses
the decays of B hadrons and measurements of branching fractions. We focus on
charmless two-body decays of B->hh.


title: Thermal Neutrons in Eas: A New Dimension in Eas Study

abstract:
  A new method to study Extensive Air Shower (EAS) hadronic component is
proposed. It is shown that addition of specific detectors for thermal neutron
detection to a standard array for EAS study can significantly improve its
performance. Results of CORSIKA based Monte Carlo simulations as well as
preliminary experimental data are presented. A proposal of novel type of EAS
array is given.


title: Measurement of the branching fraction Br(Bs -> Ds(*) Ds(*))

abstract:
  We report a measurement of the branching fraction Br(Bs -> Ds(*) Ds(*)) using
a data sample corresponding to 1.3 fb^{-1} of integrated luminosity collected
by the D0 experiment in 2002-2006 during Run II of the Fermilab Tevatron
Collider. One Ds(*) meson was partially reconstructed in the decay Ds -> phi mu
nu, and the other Ds(*) meson was identified using the decay Ds -> phi pi where
no attempt was made to distinguish Ds and Ds* states. The resulting measurement
is Br(Bs -> Ds(*) Ds(*)) = 0.039 +0.019 -0.017 (stat) +0.016 -0.015 (syst).
This was subsequently used to estimate the width difference Delta Gamma^{CP}_s
in the Bs-Bsbar system: Delta Gamma^{CP}_s / Gamma_s = 0.079 +0.038 -0.035
(stat) +0.031 -0.030 (syst).


title: Searches for Magnetic Monopoles, Nuclearites and Q-balls

abstract:
  The Searches for classical Dirac Magnetic Monopoles (MMs) at accelerators,
for GUT superheavy MMs in the penetrating cosmic radiation and for Intermediate
Mass IMMs at high altitudes are discussed. Also the searches for nuclearites
and Q-balls are considered.


title:
Inclusive Search for New Physics with Like-Sign Dilepton Events in ppbar
  Collisions at sqrt{s} = 1.96 TeV

abstract:
  We describe a search for anomalous production of events with two leptons ($e$
or $\mu$) of the same electric charge in \ppbar collisions at a center-of-mass
energy of 1.96 TeV. Many extensions to the standard model predict the
production of two leptons of the same electric charge. This search has a
significant increase in sensitivity compared to earlier searches. Using a data
sample corresponding to 1 \invfb of integrated luminosity recorded by the CDF
II detector, we observe no significant excess in an inclusive selection (expect
$33.2\pm4.7$ events, observe 44) or in a SUSY-optimized selection (expect
$7.8\pm1.1$ events, observe 13.)


title:
t-tbar Production at the Tevatron: Event Selection and Cross Section
  Measurement

abstract:
  The Fermilab Tevatron is currently the only collider capable of producing and
studying top quarks. The dominant mechanism for top quark production at the
Tevatron is t-tbar production via the strong interaction. The precise
measurement of the cross section of this process is a test of the QCD
prediction. In Run II of the Tevatron it should be possible to achieve an
experimental error on this cross section which is comparable or better than the
current theoretical precision. This paper presents the basic event selection
criteria for t-tbar events at the Tevatron and the latest measurements of the
t-tbar cross section.


title: Measurement of K^{0}_{\mu3} form factors

abstract:
  This paper reports on a new high precision measurement of the form factors of
the K_{L}\to \pi^{\pm} \mu^{\mp} \nu_{\mu} decay. The data sample of about
2.3$\times 10^{6}$ events was recorded in 1999 by the NA48 experiment at CERN.
Studying the Dalitz plot density we measured a linear, $\lambda^{'}_{+} =
(20.5\pm 2.2_{stat} \pm 2.4_{syst})\times 10^{-3}$, and a quadratic,
$\lambda^{''}_{+} = (2.6\pm 0.9_{stat} \pm 1.0_{syst})\times 10^{-3}$ term in
the power expansion of the vector form factor. No evidence was found for a
second order term for the scalar form factor; the linear slope was determined
to be $\lambda_{0} = (9.5\pm 1.1_{stat} \pm 0.8_{syst})\times 10^{-3}$. Using a
linear fit our results were: $\lambda_{+} = (26.7\pm 0.6_{stat} \pm 0.8_{syst}
)\times 10^{-3}$ and, $\lambda_{0} = (11.7\pm 0.7_{stat} \pm 1.0_{syst})\times
10^{-3}$. A pole fit of the form factors yields:
  $m_V = (905 \pm 9_{stat} \pm 17_{syst})$ MeV/c$^2$ and
  $m_S = (1400 \pm 46_{stat} \pm 53_{syst})$ MeV/c$^2$.


title:
Eta Photoproduction on the proton revisited: Evidence for a narrow
  N(1685) resonance

abstract:
  Revised analysis of $\Sigma$ beam asymmetry for
  $\eta$ photoproduction on the free proton reveals a resonant structure at
$W\sim 1.69$ GeV. Comparison of experimental data with multipole decomposition
based on the E429 solution of the SAID partial wave analysis and including
narrow states, suggests a narrow ($\Gamma \leq 15$ MeV) resonance. Possible
candidates are $P_{11}$, $P_{13}$, or $D_{13}$ resonances. The result is
considered in conjunction with the recent evidence for a bump-like structure at
$W\sim 1.67 - 1.68$ GeV in quasi-free $\eta$ photoproduction on the neutron.


title: Search for Lepton Flavour Violation in ep Collisions at HERA

abstract:
  A search for the lepton flavour violating processes ep->mu X and ep -> tau X
is performed with the H1 experiment at HERA. Final states with a muon or tau
and a hadronic jet are searched for in a data sample corresponding to an
integrated luminosity of 66.5 pb-1 for e^+ p collisions and 13.7 pb^-1 for e^-
p collisions at a centre-of-mass energy of 319 GeV. No evidence for lepton
flavour violation is found. Limits are derived on the mass and the couplings of
leptoquarks inducing lepton flavour violation in an extension of the
Buchm"uller-R"uckl-Wyler effective model. Leptoquarks produced in ep collisions
with a coupling strength of lambda=0.3 and decaying with the same coupling
strength to a muon-quark pair or a tau-quark pair are excluded at 95%
confidence level up to masses of 459 GeV and 379 GeV, respectively.


title:
Measurements of CP-Violating Asymmetries in B0 to a1(1260)^{+-} pi^{-+}
  Decays

abstract:
  We present measurements of CP-violating asymmetries in the decay B0 ->
a_1(1260)^{+-} pi^{-+} with a_1(1260)^{+-} -> pi^{-+} pi^{+-} pi^{+-}. The data
sample corresponds to 384 million B B-bar pairs collected with the BaBar
detector at the PEP-II asymmetric B-factory at SLAC. We measure the
CP-violating asymmetry A^{a1pi}_{CP}=-0.07+-0.07+-0.02, the mixing-induced CP
violation parameter S_{a1pi}= 0.37 +-0.21+-0.07, the direct CP violation
parameter C_{a1pi}=-0.10+-0.15+-0.09, and the parameters
DeltaC_{a1pi}=0.26+-0.15+-0.07 and DeltaS_{a1pi}=-0.14+-0.21+-0.06. From these
measured quantities we exstract the angle alpha_{eff}= 78.6^{0} +- 7.3^{0}.


title: LHCb Upgrade Plans

abstract:
  The LHCb experiment will operate for about five years at a luminosity of
2x10^32 cm^-2 s^-1 and plans are to accumulate a data sample of ~10 fb^-1. Here
we present the physics programme and detector design for a future high
luminosity phase of the LHCb experiment. An upgraded LHCb experiment would
operate at ten times the design luminosity, i.e. at ~2x10^33 cm^-2 s^-1 and
aims to collect a data sample of ~100 fb^-1 over five years. This programme
would allow the probe of new physics at an unprecedented level. Key
measurements include the B^0_s mixing phase phi_s in B^0_s -> J/\psi phi and
B^0_s -> phi phi decays with a significant sensitivity to the small Standard
Model prediction and a very precise measurement of the CKM angle gamma in tree
diagram decays. Initial studies of the modified LHCb trigger and detectors are
presented. The upgraded LHCb experiment can run with or without an LHC
luminosity upgrade.
