title:
Updated Estimate of the Muon Magnetic Moment Using Revised Results from
  e+e- Annihilation

abstract:
  A new evaluation of the hadronic vacuum polarization contribution to the muon
magnetic moment is presented. We take into account the reanalysis of the
low-energy e+e- annihilation cross section into hadrons by the CMD-2
Collaboration. The agreement between e+e- and tau spectral functions in the pi
pi channel is found to be much improved. Nevertheless, significant
discrepancies remain in the center-of-mass energy range between 0.85 and 1.0
GeV, so that we refrain from averaging the two data sets. The values found for
the lowest-order hadronic vacuum polarization contributions are a_mu[had,LO] =
(696.3 +- 6.2[exp] +- 3.6[rad])e-10 (e+e- -based) and a_mu[had,LO] = (711.0 +-
5.0[exp] +- 0.8[rad] +- 2.8[SU2])e-10 (tau-based), where the errors have been
separated according to their sources: experimental, missing radiative
corrections in e+e- data, and isospin breaking. The corresponding Standard
Model predictions for the muon magnetic anomaly read a_mu = (11,659,180.9 +-
7.2[had] +- 3.5[LBL] +- 0.4[QED+EW])e-10 (e+e- -based) and a_mu = (11,659,195.6
+- 5.8[had] +- 3.5[LBL] +- 0.4[QED+EW])e-10 (tau-based), where the errors
account for the hadronic, light-by-light (LBL) scattering and electroweak
contributions. The deviations from the measurement at BNL are found to be (22.1
+- 7.2 +- 3.5 +- 8.0)e-10 (1.9 sigma) and (7.4 +- 5.8 +- 3.5 +- 8.0)e-10 (0.7
sigma) for the e+e- and tau-based estimates, respectively, where the second
error is from the LBL contribution and the third one from the BNL measurement.

title:
Pair production of charged Higgs bosons in association with bottom quark
  pairs at the Large Hadron Collider

abstract:
  We study the process gg -> b bbar H+ H- at large tan(beta), where it
represents the dominant production mode of charged Higgs boson pairs in a Type
II 2-Higgs Doublet Model, including the Minimal Supersymmetric Standard Model.
The ability to select this signal would in principle enable the measurements of
some triple-Higgs couplings, which in turn would help understanding the
structure of the extended Higgs sector. We outline a selection procedure that
should aid in disentangling the Higgs signal from the main irreducible
background. This exploits a signature made up by `four b-quark jets, two
light-quark jets, a tau-lepton and missing energy'. While, for tan(beta) \gsim
30 and over a significant M_H+/- range above the top mass, a small signal
emerges already at the Large Hadron Collider after 100 fb^{-1}, ten times as
much luminosity would be needed to perform accurate measurements of Higgs
parameters in the above final state, rendering this channel a primary candidate
to benefit from the so-called `Super' Large Hadron Collider option, for which a
tenfold increase in instantaneous luminosity is currently being considered.


title:
O(\alpha \alpha_s) correction to the pole mass of the t-quark within the
  Standard Model

abstract:
  We have calculated the O(\alpha \alpha_s) contributions to the relationship
between the MS-mass and the pole of the t-quark propagator in the Standard
Model in the limit of a diagonal CKM matrix and for a massless b-quark.
Analytical results for the so far unknown master-integrals appearing in the
calculation are also given.


title:
Deconfinement Phase Transition in an Expanding Quark system in
  Relaxation Time Approximation

abstract:
  We investigated the effects of nonequilibrium and collision terms on the
deconfinement phase transition of an expanding quark system in Friedberg-Lee
model in relaxation time approximation. By calculating the effective quark
potential, the critical temperature of the phase transition is dominated by the
mean field, while the collisions among quarks and mesons change the time
structure of the phase transition significantly.


title: Fermionic partner of Quintessence field as candidate for dark matter

abstract:
  Quintessence is a possible candidate for dark energy. In this paper we study
the phenomenologies of the fermionic partner of Quintessence, the Quintessino.
Our results show that, for suitable choices of the model parameters, the
Quintessino is a good candidate for cold or warm dark matter. In our scenario,
dark energy and dark matter of the Universe are connected in one chiral
superfield.


title: "Point-form" estimate of the pion form factor revisited

abstract:
  The pion form factor calculation in the ``point-form'' of relativistic
quantum mechanics is re-considered. Particular attention is given to the
relation between the momentum of the system and the momentum transfer as well
as to the quark current.


title: Limit on the fermion masses in technicolor models

abstract:
  Recently it has been pointed out that no limits can be put on the scale of
fermion mass generation $(M)$ in technicolor models, because the relation
between the fermion masses $(m_f)$ and $M$ depends on the dimensionality of the
interaction responsible for generating the fermion mass. Depending on this
dimensionality it may happens that $m_f$ does not depend on $M$ at all. We show
that exactly in this case $m_f$ may reach its largest value, which is almost
saturated by the top quark mass. We make few comments on the question of how
large can be a dynamically generated fermion mass.


title: QCD Corrections to Photoproduction of W Bosons at HERA

abstract:
  W bosons can be produced in the channels e+- p --> W+- + X at HERA thus
allowing anomalous trilinear couplings among the gauge bosons to be probed. We
discuss the next-to-leading order (NLO) QCD corrections to the photoproduction
of W bosons with finite transverse momentum at HERA. The higher-order QCD
corrections reduce the factorization scale dependence significantly and modify
the leading-order (LO) cross sections by +- O(10%).


title:
Next-to-next-to-leading order soft-gluon corrections in top quark
  hadroproduction

abstract:
  We calculate next-to-next-to-leading order soft-gluon corrections to top
quark total and differential cross sections in hadron colliders. We increase
the accuracy of our previous estimates by including additional subleading
terms, including next-to-next-to-next-to-leading-logarithmic and some virtual
terms. We show that the kinematics dependence of the cross section vanishes
near threshold and is reduced away from it. The factorization and
renormalization scale dependence of the cross section is also greatly reduced.
We present results for the top quark total cross sections and transverse
momentum distributions at the Tevatron and the LHC.


title:
The Study of the Heisenberg-Euler Lagrangian and Some of its
  Applications

abstract:
  The Heisenberg-Euler Lagrangian is not only a topic of fundamental interest,
but also has a rich variety of diverse applications in astrophysics, nonlinear
optics and elementary particle physics etc. We discuss the series
representation of this Lagrangian and a few of its applications in this study.
[In an appendix, we discuss issues related to the renormalization - and the
renormalization-group invariance - of the Heisenberg-Euler Lagrangian and its
two-loop generalization.]


title: A mixing-independent construction of the unitarity triangle

abstract:
  The study of charmless hadronic two-body decays of B mesons is one of the
most fascinating topics in B physics. A construction of the unitarity triangle
based on such decays is presented, which is independent of B-B(bar) and
K-K(bar) mixing. It provides stringent tests of the Standard Model with small
theoretical uncertainties.


title: Direct CP Violation and Isospin Triangles of B->\pi\pi Decays

abstract:
  The recent observation of B^0_d->\pi^0\pi^0 and \bar{B}^0_d->\pi^0\pi^0 decay
modes allows us to make a fresh isospin analysis of B->\pi\pi transitions. We
find that current experimental data can impose some model-independent
constraints on the parameter space of direct CP violation in B_d->\pi^+\pi^-
and B_d->\pi^0\pi^0. Furthermore, we establish a direct relationship between
the weak phase \alpha and the charge-averaged branching fractions and
CP-violating asymmetries of B->\pi\pi decays.


title:
Neutral Higgs boson pair production via $\gamma\gamma$ collision in the
  minimal supersymmetric standard model at linear colliders

abstract:
  We investigate in detail the $\gamma\gamma$ fusion production mechanisms of
two neutral Higgs bosons ($h^0A^0$, $ H^0A^0$, $h^0H^0$ and $H^0H^0$) within
the framework of the mSUGRA-inspired minimal supersymmetric standard
model(MSSM) at an $e^+e^-$ linear colliders, which provide a probe of the
trilinear Higgs self-couplings. We calculate the dependence of the production
rates on Higgs boson masses, the ratio of the vacuum expectation values $\tan
\beta$ and the CMS energy $\sqrt{s}$. We find that the cross section for the
$H^0H^0$ production at LC can reach $0.2 fb$, while the cross section of
$A^0H^0$ production is only $10^{-4}\sim 10^{-3} fb$ under our parameters.


title: Resolving degeneracies for different values of $\theta_{13}$

abstract:
  We discuss options to resolve correlations and degeneracies with combinations
of future neutrino long-baseline experiments. We use a logarithmic scale of
$\sin^2 2 \theta_{13}$ as a representation for a systematical classification of
the experiments.


title: Observing Direct CP Violation in Untagged B-Meson Decays

abstract:
  Direct CP violation can exist in untagged B-meson decays to self-conjugate,
three-particle final states; it would be realized as a population asymmetry in
the untagged decay rate across the mirror line of the Dalitz plot of the
three-body decay. We explore the numerical size of this direct CP-violating
effect in a variety of B-meson decays to three pseudoscalar mesons; we show
that the resulting asymmetry is comparable to the partial rate asymmetry in the
analogous tagged decays, making the search for direct CP violation in the
untagged decay rate, for which greater statistics accrue, advantageous.


title: Forces, fluxes and quasi-particles in hot QCD

abstract:
  These lectures start with a brief overview of salient features of the
critical region of hot QCD. The main emphasis is on the accurate description of
static plasma observables by the well-known hierarchy of reduced actions
combined with 3D simulations above T\sim 2T_c. A striking pattern emerges, put
in perspective by completing the quasi-particle picture


title:
Are there non-strange low-lying penta-quarks and can we understand their
  width

abstract:
  We argue that the lightest isospin 1/2 partners of the Z^+(1530) s(bar)uudd
penta-quark predicted by Diakonov, Petrov and Polyakov are not the N(1710)
mixed anti-decuplet states, but the pure non-strange u(bar)(ud)(ud) and
d(bar)(ud)(ud) penta-quark states which may lie as low as 1200 MeV. The
expected low width of a few MeV of such a putative state may explain why it was
missed in phase shift analyzes of pion-nucleon scattering.


title:
Three loop soft running, benchmark points and semi-perturbative
  unification

abstract:
  We consider three-loop $\beta$-function corrections to the sparticle spectrum
in the MSSM, with particular emphasis on Snowmass Benchmark points. The three
loop running has little effect on the weakly interacting particle spectrum, but
for the squark masses the effect can be comparable to, or greater than, that of
two loop running. We extend the analysis to the semi-perturbative unification
scenario, where the impact of the three loop corrections becomes even more
dramatic.


title:
$\Theta^+$ in a chiral constituent quark model and its interpolating
  fields

abstract:
  The recently discovered pentaquark $\Theta^+$ is described within the chiral
constituent quark model. Within this picture the flavor-spin interaction
between valence quarks inverts the $(1s)^4$ and $(1s)^3(1p)$ levels of the
four-quark subsystem and consequently the lowest-lying pentaquark is a positive
parity, I=0, J=1/2 state of the flavor antidecuplet, similar to the soliton
model prediction. Contrary to the soliton model, however, the quark picture
predicts its spin-orbit partner with $J=3/2$. Different interpolating fields
intended for lattice calculations of $\Theta^+$ are constructed, which have a
maximal overlap with this baryon if it is indeed a quark excitation in the 5Q
system.


title: Partons and Jets at the LHC

abstract:
  I review some issues related to short distance QCD and its relation to the
experimental program of the Large Hadron Collider (LHC) now under construction
in Geneva.


title: Summary of Spin Physics Parallel Sessions

abstract:
  We summarize the activities in the spin physics parallel sessions of the
$8^{\rm th}$ conference on intersections between particle and nuclear physics.


title: Perturbative and non-perturbative aspects of heavy-quark fragmentation

abstract:
  We describe a new approach to heavy-quark fragmentation which is based on a
resummed perturbative calculation and parametrization of power corrections,
concentrating on the z -> 1 limit, where the heavy meson carries a large
fraction of the momentum of the initial quark. It is shown that the leading
power corrections in this region are controlled by the scale m(1-z). Renormalon
analysis is then used to extend the perturbative treatment of soft and
collinear radiation to the non-perturbative regime. Theoretical predictions are
confronted with data on B-meson production in e+e- annihilation.


title:
Supergravity Interactions in the SU(4)XU(1)Vacuum of Global
  Supersymmetry

abstract:
  It is shown that quarks and leptons can couple intrinsically to pure
supergravity, preserving for this context the degeneracy of globally
supersymmetric vacua, and specifically preserving the vacuum that is
characterized by SU(4)XU(1). A fundamental representation of SUSY SU(4)XU(1) is
constructed in terms of quarks, and it is demonstrated that the symmetry of
this fundamental representation is invariant under supergravity interactions
that produce quark-lepton transitions. The importance of this tensorial flavor
structure is that it predicts a new, seventh quark of charge -1/3, a
left-handed (non-strange) version of the strange quark.


title: The Pion Velocity at Chiral Restoration and the Vector Manifestation

abstract:
  We study the effects of Lorentz non-invariance on the physical pion velocity
at the critical temperature $T_c$ in an effective theory of hidden local
symmetry (HLS) with the "vector manifestation" fixed point. We match at a
"matching scale" $\Lambda_M$ the axial-vector current correlator in the HLS
with the one in the operator product expansion for QCD, and present the
matching condition to determine the bare pion velocity. We find that the
physical pion velocity, which is found to be one at $T=T_c$ when starting from
the Lorentz invariant bare HLS, remains close to one with the Lorentz
non-invariance, $v_\pi (T_c) = 0.83 - 0.99$. This result is quite similar to
the pion velocity in dense matter.


title:
R-parity violation effect on the top-quark pair production at linear
  colliders

abstract:
  We investigate in detail the effects of the R-parity lepton number violation
in the minimal supersymmetric standard model (MSSM) on the top-quark pair
production via both $e^--e^+$ and $\gamma-\gamma$ collision modes at the linear
colliders. We find that with the present experimental constrained $\rlap/{R}$
parameters, the effect from $\rlap/{R}$ interactions on the processes
$e^+e^-\to t\bar{t}$ and $e^+e^- \to \gamma\gamma \to t\bar{t}$ could be
significant and may reach -30% and several percent, respectively. Our results
show that the $\rlap/{R}$ effects are sensitive to the c.m.s. energy and the
relevant $\rlap/{R}$ parameters. However, they are not sensitive to squark and
slepton masses when $m_{\tilde{q}} \geq 400 GeV$ (or $m_{\tilde{l}} \geq 300
GeV$) and are almost independent on the $\tan\beta$


title: Note on spin carried by quarks

abstract:
  We note that recent results on the role of final state interactions in deep
inelastic scattering make more complicated an extraction of a nucleon spin
fraction carried by quarks from the experimental data obtained in deep
inelastic scattering.


title: Glueballs, closed fluxtubes and eta(1440)

abstract:
  The $eta_L(1410)$ component of the $\eta(1440)$ pseudoscalar has strong
affinity for glue. But its mass is incompatible with lattice simulations that
predict a much higher value for the $0^{-+}$ glueball. As a consequence it has
been suggested that $\eta_L(1410)$ could signal physics beyond the Standard
Model. Here we argue that if glueballs are closed gluonic fluxtubes then
$\eta_L(1410)$ is a prime candidate for the $0^{-+}$ glueball. Furthermore, in
the absence of parity violating terms its mass should be degenerate with that
of the $0^{++}$ glueball. We also suggest that the decay properties of such
glueballs could be employed as probes for extra dimensions.


title: Can Low Mass Scalar Meson Nonet Survive in Large N_c Limit ?

abstract:
  We study, within an approximate Inverse Amplitude Method to unitarize Chiral
Perturbation Theory, whether low mass scalar mesons can survive in large N_c
regime, and show that vector mesons such as \rho and K^* survive as narrow
width resonances, but all of the scalar meson nonet below 1GeV fade out as N_c
becomes large.


title: Magnetic moments of exotic pentaquarks in the chiral quark-soliton model

abstract:
  We investigate the magnetic moments of the baryon antidecuplet within the
framework of the chiral quark-soliton model in the chiral limit in a
``\emph{model-independent}'' approach. Sum rules for the magnetic moments are
derived. The magnetic moment of $\Theta^{+}$ is found to be about $0.2\sim 0.3
\mu_{N}$.


title:
Rare Decays $B^0 \to D_s^{(*)+} D_s^{(*)-}$ and $B_s^0 \to D^{(*)+}
  D^{(*)-}$ in Perturbative QCD Approach

abstract:
  In decay modes $B^0 \to D_s^{(*)+} D_s^{(*)-}$ and $B_s^0 \to D^{(*)+}
D^{(*)-}$, none of quarks in final states is the same as one of $B$ meson. They
can occur only via annihilation diagrams in the Standard Model. In the heavy
quark limit, we try to calculate the branching ratios of these decays in
perturbative QCD approach without considering the soft final state interaction.
We found branching ratios of $B^0 \to D_s^{(*)+} D_s^{(*)-}$ are at the order
of $ 10^{-5}$, and branching ratios of $B_s^0 \to D^{(*)+} D^{(*)-}$ are of
$10^{-3}$. Those decay modes will be measured in $B$ factories and LHC-b
experiments.


title: $J/\psi + c + \bar{c}$ Photoproduction in $e^+ e^-$ Scattering

abstract:
  We investigate the $J/\psi$ + c + $\bar{c}$ photoproduction in $e^+ e^-$
collision at the LEP II energy. The physical motivations for this study are: 1)
such next-to-leading order(NLO) process was not considered in previous
investigations of $J/\psi$ photoproduction in $e^+ e^-$ interaction, and it is
worthwhile to do so in order to make sound predictions for experimental
comparison; 2) from recent Belle experiment results, the process with same
final states at the $B$ factory has a theoretically yet unexplainable large
fraction; hence it is interesting to see what may happen at other colliders; 3)
the existing LEP data are marginal in observing such process, and at the planed
Linear Colliders(LCs) this process can be measured with high accuracy; 4) it is
necessary to take this process into consideration in the aim of elucidating the
quarkonium production mechanism, especially in testing the universality of
NRQCD nonperturbative matrix elements via $J/\psi$ photoproduction in
electron-position collisions.


title: Balance functions in coalescence model

abstract:
  It is shown that the quark-antiquark coalescence mechanism for pion
production allows to explain the small width of the balance function observed
for central collisions of heavy ions, provided effects of the finite acceptance
region and of the transverse flow are taken into account. In contrast, the
standard hadronic cluster model is not compatible with this data.


title:
Separation of soft and collinear singularities from one-loop N-point
  integrals

abstract:
  The soft and collinear singularities of general scalar and tensor one-loop
N-point integrals are worked out explicitly. As a result a simple explicit
formula is given that expresses the singular part in terms of 3-point
integrals. Apart from predicting the singularities, this result can be used to
transfer singular one-loop integrals from one regularization scheme to another
or to subtract soft and collinear singularities from one-loop Feynman diagrams
directly in momentum space.


title: Triple gauge vertices at one-loop level in THDM

abstract:
  Renormalized triple gauge vertices (TGV) are examined within the
two-Higgs-doublet model of electroweak interactions. Deviations of the TGV from
their standard-model values are calculated at the one-loop level, in the
on-shell renormalization scheme. As a consistency check, UV divergence
cancellations anticipated on symmetry grounds are verified explicitly.
Dependence of the TGV finite parts on the masses of possible heavy Higgs
scalars is discussed briefly.


title:
Hard probes in heavy ion collisions at the LHC: PDFs, shadowing and $pA$
  collisions

abstract:
  This manuscript is the outcome of the subgroup ``PDFs, shadowing and $pA$
collisions'' from the CERN workshop ``Hard Probes in Heavy Ion Collisions at
the LHC''. In addition to the experimental parameters for $pA$ collisions at
the LHC, the issues discussed are factorization in nuclear collisions, nuclear
parton distributions (nPDFs), hard probes as the benchmark tests of
factorization in $pA$ collisions at the LHC, and semi-hard probes as
observables with potentially large nuclear effects. Also, novel QCD phenomena
in $pA$ collisions at the LHC are considered. The importance of the $pA$
program at the LHC is emphasized.


title: QCD Sum Rules on the Light-Cone, Factorisation and SCET

abstract:
  The accurate calculation of weak heavy-to-light form factors is crucial for
the determination of CKM matrix elements from experimental data on B decays. In
SCET, the soft-collinear effective theory, these form factors can, in the heavy
quark limit, be split into a factorisable part that is calculable in
perturbation theory, and a nonfactorisable part that observes certain
spin-symmetries. I discuss the relation between the SCET factorisation formulas
and the heavy quark limit of the corresponding QCD sum rules on the light-cone.
I also analyse the numerical size of factorisable and nonfactorisable parts and
corrections suppressed by powers of the b quark mass.


title: Quark distributions in polarized and nonpolarized hadrons

abstract:
  Valence quark distributions in pion, polarizied $\rho$ mesons and nucleon in
the region of intermediate $x$ are obtained by generalizied QCD sum rules. It
is shown, that polarization effects are very significant. The strong
suppression of quark and gluon sea distributions in longitudinally polarizied
$\rho$ mesons is found.


title:
WMAPing the Universe: Supersymmetry, Dark Matter, Dark Energy, Proton
  Decay and Collider Physics

abstract:
  In this review we discuss constraints on minimal supersymmetric models of
particle physics implied by the recent astrophysical observations of WMAP.
Although the prospects of detecting supersymmetry increase and 90 percent of
the available MSSM parameter space can safely be reached by the sensitivity of
future colliders, nevertheless we pay particular emphasis on discussing regions
of the appropriate phase diagrams, which -if realized - would imply that
detection of supersymmetry, at least in the context of minimal models, could be
out of colliders reach. We also discuss the importance of a precise
determination of the radiative corrections to the muon anomalous magnetic
moment, both theoretically and experimentally. Finally, we briefly commend upon
recent evidence, supported by observations, on a dark energy component of the
Universe, of as yet unknown origin, covering 73 percent of its energy content.


title: Quintessentially Flat Scalar Potentials

abstract:
  Both inflationary and quintessence cosmologies require scalar fields which
roll very slowly over cosmological time scales, and so typically demand
extremely flat potentials. Sufficiently flat potentials are notoriously
difficult to obtain from realistic theories of microscopic physics, and this
poses a naturalness problem for both types of cosmologies. We propose a
brane-world-based microscopic mechanism for generating scalar potentials which
can naturally be flat enough for both types of cosmological applications. The
scalars of interest are higher-dimensional bulk pseudo-Goldstone bosons whose
scale of symmetry breaking is exponentially suppressed in the
higher-dimensional theory by the separation between various branes. The light
scalars appear in the effective 4D theory as pseudo-Goldstone bosons. Since
naturalness problems are more severe for quintessence models, motivated by our
construction we explore in more detail the possibilities for using
pseudo-Goldstone bosons to build quintessence models. Depending on how the
cosmological constant problem is solved, these models typically imply the
universe is now entering a matter-dominated oscillatory phase for which the
equation of state parameter w = p/rho oscillates between w = 1 and w = -1.


title:
Constraints on Field Theoretical Models for Variation of the Fine
  Structure Constant

abstract:
  Recent theoretical ideas and observational claims suggest that the fine
structure constant alpha may be variable. We examine a spectrum of models in
which alpha is a function of a scalar field. Specifically, we consider three
scenarios: oscillating alpha, monotonic time variation of alpha, and
time-independent alpha that is spatially varying. We examine the constraints
imposed upon these theories by cosmological observations, particle detector
experiments, and ``fifth force'' experiments. These constraints are very strong
on models involving oscillation, but cannot compete with bounds from the Oklo
sub-nuclear reactor on models with monotonic time-like variation of alpha. One
particular model with spatial variation is consistent with all current
experimental and observational measurements, including those from two seemingly
conflicting measurements of the fine structure constant using the many
multiplet method on absorption lines.


title:
Implications of the DAMA and CRESST experiments for mirror matter-type
  dark matter

abstract:
  Mirror atoms are expected to be a significant component of the galactic dark
matter halo if mirror matter is identified with the non-baryonic dark matter in
the Universe. Mirror matter can interact with ordinary matter via gravity and
via the photon-mirror photon kinetic mixing interaction -- causing mirror
charged particles to couple to ordinary photons with effective electric charge
$\epsilon e$. This means that the nuclei of mirror atoms can elastically
scatter off the nuclei of ordinary atoms, leading to nuclear recoils, which can
be detected in existing dark matter experiments. We show that the dark matter
experiments most sensitive to this type of dark matter candidate (via the
nuclear recoil signature) are the DAMA/NaI and CRESST/Sapphire experiments.
Furthermore, we show that the impressive annual modulation signal obtained by
the DAMA/NaI experiment can be explained by mirror matter-type dark matter for
$|\epsilon | \sim 4 \times 10^{-9}$ and is supported by DAMA's absolute rate
measurement as well as the CRESST/Sapphire data. This value of $|\epsilon |$ is
consistent with the value obtained from various solar system anomalies
including the Pioneer spacecraft anomaly, anomalous meteorite events and lack
of small craters on the asteroid Eros. It is also consistent with standard BBN.


title:
$B\to \phi K_s$ versus Electric Dipole Moment of $^{199}$Hg Atom in
  Supersymmetric Models with Right-handed Squark Mixing

abstract:
  The correlation between the CP asymmetry in $B\to \phi K_s$ ($S_{\phi K_s}$)
and the chromoelectric dipole moment (CEDM) of strange quark ($d_s^C$), which
is constrained by the electric dipole moment (EDM) of $^{199}$Hg, is studied in
the supersymmetric (SUSY) models with the right-handed squark mixing. It is
known that, if the right-handed bottom and strange squarks have a CP-violating
mixing, such as in the SUSY SU(5) GUT with right-handed neutrinos, the induced
gluon-penguin diagram may give a sizable contribution to $S_{\phi K_s}$.
However, when the left-handed bottom and strange squarks also have a mixing,
the conspiracy of the left and right-handed squarks may lead to a sizable
$d_s^C$, which is enhanced by $m_b/m_s$. While the estimate for the EDM of
$^{199}$Hg, induced by $d^C_s$, might have large uncertainties due to the
hadron and nuclear dynamics, the current bound implies the gluon penguin
contribution by the right-handed squarks to $S_{\phi K_s}$ should be suppressed
and the deviation of $S_{\phi K_s}$ from the Standard Model may not be so
large. Also, we discuss the constraint from the EDM of $^{199}$Hg in the SUSY
SU(5) GUT with the right-handed neutrinos.


title:
The Rare Radiative Annihilation Decays $\bar{B}^0_{s,d} \to
  J/\psi\gamma$

abstract:
  We investigate the physics potential of the annihilation decays
$\bar{B}^0_{s,d} \to J/\psi$ $\gamma$ in the Standard Model and beyond. In
naive factorization approach, the branching ratios are estimated to be
$\mathcal{B}(\bar{B}^0_s \to J/\psi\gamma)=1.40\times 10^{-6}$ and
$\mathcal{B}(\bar{B}^0_d \to J/\psi\gamma)=5.29\times 10^{-8}$. In the
framework of QCD factorization, we compute the non-factorizable corrections and
get $\mathcal{B}(\bar{B}^0_s \to J/\psi\gamma) = 2.11\times10^{-7}$,
$\mathcal{B}(\bar{B}^0_d \to J/\psi\gamma) =7.65\times10^{-9}$. Future
measurements of these decays would be useful for testing the factorization
frameworks. The smallness of these decays in the SM make them sensitive probes
of New Physics. As an example, we will consider the possible admixture of (V+A)
charge current to the standard (V-A) current. This admixture will give
significant contributions to the decays.


title: Weak phases from topological-amplitude parametrization

abstract:
  We propose a parametrization for two-body nonleptonic $B$ meson decays, in
which the various topologies of amplitudes are counted in terms of powers of
the Wolfenstein parameter $\lambda\sim 0.22$. The weak phases and the
amplitudes are determined by comparing this parametrization with available
measurements. It is possible to obtain the phase $\phi_3$ from the $B\to K\pi$
data up to theoretical uncertainty of $O(\lambda^3)\sim 1%$. The recently
measured $B_d^0\to\pi^0\pi^0$ branching ratio implies a large color-suppressed
or penguin amplitude, and that the extraction of the phase $\phi_2$ from the
$B\to\pi\pi$ data may suffer theoretical uncertainty more than the expected one
of $O(\lambda^2)\sim 5%$.


title: Implications of Bi-Large Neutrino Mixing on GUTs

abstract:
  Under the assumptions that 1) the quark/lepton mass matrices take
Froggatt-Nielsen's factorized power form \lambda^{\psi_i+\psi_j} with anomalous
U(1) charges \psi_i, and 2) the U(1) charges \psi_i respect the SU(5) GUT
structure, we show that the quark mass data and the mass-squared difference
ratio of solar and atmospheric neutrinos, as inputs, necessarily imply that
both the 1-2 and 2-3 mixings in the MNS matrix U_{MNS} are large. This analysis
also gives a prediction that U_{e3}\equiv (U_{MNS})_{13} is of order \lambda
\sim (0.1 - 0.5). We also add an argument that E_6 GUT is favored.

Form Factors and semileptonic decay of $D_s^+\to \phi \bar{\ell}\nu$
  from QCD sum rule

abstract:
  We calculate $D_s^+\to \phi$ transition form factors $V$, $A_0$, $A_1$ and
$A_2$, and study semileptonic decay of $D_s^+\to \phi \bar{\ell}\nu$ based on
QCD sum rule method. We compare our results of the ratios of $V(0)/A_1(0)$,
$A_2(0)/A_1(0)$, $\Gamma_L/\Gamma_T$, and the total decay branching ratio of
$D_s^+\to \phi \bar{\ell}\nu$ with experimental data, and find that they are
consistent.


title: Effect of H^\pm on D^\pm_s\to \mu^\pm\nu and D^\pm_s\to \tau^\pm\nu

abstract:
  We investigate the effect of a charged Higgs boson (H^\pm) on the decays
D^\pm_s\to \mu^\pm\nu and D^\pm_s\to \tau^\pm\nu, which will be measured with
high precision at forthcoming CLEO-c. We show that a H^\pm can suppress the
branching ratios by 10% \to 15% from the Standard Model prediction, and we
emphasize that such contributions should not be overlooked when comparing
lattice calculations of f_{D_s} to the values obtained from these decays.


title: Leptogenesis

abstract:
  I present the theoretical basis for Leptogenesis and its implications for the
structure of the universe. It is suggested that density fluctuations grow
during the transition period and remnants of this effect should be sought in
the universe. The relation between theories with Majorana neutrinos and low
energy phenomena, including oscillations, advanced considerably during the past
two years with a consistent picture developed in several models.


title:
Sensitivity of CKM fits to theoretical uncertainties and their
  representation

abstract:
  There is now a rapidly growing body of experimental data relevant to the
question of whether the standard model CKM quark mixing matrix is a correct
description of \CP-violation as well as of non--\CP-violating flavor decay
processes. In the detailed comparisons with theoretical predictions that are
required to investigate this, a key challenge has been the representation of
non-statistical uncertainties, especially those arising in theoretical
calculations. The analytical procedures that have been used to date require
procedural value judgments on this matter that color the interpretation of the
quantitative results they produce. Differences arising from these value
judgments in the results obtained from the various global CKM fitting
techniques in the literature are of a scale comparable to those arising from
the other uncertainties in the input data and therefore cannot be ignored.
  We have developed techniques for studying and visualizing the sensitivity of
global CKM fits to non-statistical uncertainties and their parameterization, as
well as techniques for visual evaluation of the consistency of experimental and
theoretical inputs that minimize the implicit use of such value judgments,
while illuminating their effects. We present these techniques and the results
of such studies using recently updated theoretical and experimental inputs,
discuss their implications for the interpretation of global CKM fits, and
illustrate their possible future application as the uncertainties on the inputs
are improved over the next several years.


title: Open-charm meson resonances with negative strangeness

abstract:
  We study heavy-light meson resonances with quantum numbers J^P=0^+ and
J^P=1^+ in terms of the non-linear chiral SU(3) Lagrangian. Adjusting the free
parameters that arise at subleading order to reproduce the mass of the D(2420)
resonance as well as the new states established recently by the BABAR, CLEO and
BELLE collaborations we obtain refined masses for the anti-triplet and sextet
states. Bound states of antikaons at the D(1867) and D(2008) mesons are
predicted at 2352 MeV (J^P=0^+) and 2416 MeV (J^P=1^+). In addition we
anticipate a narrow scalar state of mass 2389 MeV with (I,S)=(1/2,0)


title:
Radiative CP violation in the Higgs sector of the Next-to-minimal
  supersymmetric model

abstract:
  We investigate the neutral Higgs sector in the next-to-minimal supersymmetric
standard model (NMSSM) with explicit CP violation at the one-loop level by
using the effective potential method. In general, explicit CP violation is
possible at the tree-level in the Higgs potential of the NMSSM, which may
possess a complex phase. The tree-level Higgs potential can be made CP
conserving by assuming that all the relevant parameters are real. However, the
CP-conserving Higgs potential at the tree level may still develop complex
phases at the one-loop level through radiative corrections. These complex
phases exhibit explicit CP violation through the mixings between the scalar and
pseudoscalar Higgs bosons. One of the complex phases arise in the neutralino
sector. For a particular choice of the relevant parameter values, the
scalar-pseudoscalar mixings are found to strongly dependent on this phase.
Meanwhile, for a wide region in the parameter space, the ratios of CP mixing
elements of the neutral Higgs boson mass matrix to CP non-mixing ones increase
weakly against this phase. Also, the neutral Higgs boson masses are roughly
stable against the variation of this phase.


title:
Ground state correlations in Deep Inelastic Scattering and the Drell-Yan
  process

abstract:
  Non-perturbative corrections to the LO cross section formulae for DIS and the
Drell-Yan process were calculated. The interaction of partons was taken into
account via dressing the incoming quark lines with spectral functions. We found
the effect of ground state correlation in DIS to be large in the region of
small Bjorken x and low momentum transfer Q. For a quark width of the order of
200 MeV, the deviation from parton model cross section reaches as much as 50%
for Q^2=10 GeV^2. On the other hand, for the values of Q well above the
resonance region, the effect of ISI turned out to be small in DIS, but still
substantial for the triple differential Drell-Yan cross section. Our
calculations show that the shape of the high mass Drell-Yan pair transverse
momentum distribution is fully determined by quark off-shellness. From
comparison to the resent data on the Drell-Yan cross section from NuSea
collaboration, we obtained for the quark width in the nucleon the value about
200 MeV.


title: TASI Lectures on Effective Field Theories

abstract:
  These notes are a written version of a set of lectures given at TASI-02 on
the topic of effective field theories. They are meant as an introduction to
some of the latest techniques and applications in the field.


title: K Kbar photoproduction and S-P wave interference

abstract:
  Results of a new analysis of the $K^+K^-$ photoproduction at two photon
energies $E_\gamma = 4{GeV}$ and $5.65{GeV}$ with a particular emphasis on the
$S$-wave production are presented. We show that the proper treatment of all the
helicity components of the $S$- and $P$-waves enables one to eliminate the
reported discrepancies in extraction of the $S$-wave photoproduction cross
section from experimental data.


title: The low lying glueball spectrum

abstract:
  The complete low-lying positive charge conjugation glueball spectrum is
obtained from QCD. The formalism relies on the construction of an efficient
quasiparticle gluon basis for Hamiltonian QCD in Coulomb gauge. The resulting
rapidly convergent Fock space expansion is exploited to derive quenched
low-lying glueball masses with no free parameters which are in remarkable
agreement with lattice gauge theory.


title:
Factorization fits and the unitarity triangle in charmless two-body B
  decays

abstract:
  We present fits to charmless hadronic B decay data from the BaBar, Belle and
Cleo experiments using two theoretical models: (i) the QCD factorization model
of Beneke et al. and (ii) QCD factorization complemented with the so-called
charming penguins of Ciuchini et al. When we include the data from
pseudoscalar-vector decays the results favor the incorporation of the charming
penguin terms. We also fit results for the unitarity triangle parameters and
the CP-violating asymmetries.


title:
High energy tau neutrinos: production, propagation and prospects of
  observations

abstract:
  High energy tau neutrinos with energy greater than several thousands of GeV
may be produced in some astrophysical sites. A summary of the intrinsic high
energy tau neutrino flux estimates from some representative astrophysical sites
is presented including the effects of neutrino flavor oscillations. The
presently envisaged prospects of observations of the oscillated high energy tau
neutrino flux are mentioned. In particular, a recently suggested possibility of
future observations of Earth-skimming high energy tau neutrinos is briefly
discussed.


title: Spinodal decomposition during the hadronization stage at RHIC?

abstract:
  The expansion of strongly interacting matter formed in high-energy nuclear
collisions drives the system through the region of phase coexistence. The
present study examines the associated spinodal instability and finds that the
degree of amplification may be sufficient to raise the prospect of using the
spinodal pattern formation as a diagnostic tool for probing the hadronization
phase transition.


title: Some remarks on geometric scaling

abstract:
  In order to explain a striking symmetry of the HERA data for virtual
photon-proton cross section, I propose a simple model based on the elementary
2-gluon exchange dipole-dipole cross section, and which exhibits geometric
scaling. I also suggest that geometric scaling should manifest itself in
exclusive processes. A preliminary search for this property in the HERA data is
presented.


title: Vacuum replicas in two-dimensional QCD

abstract:
  Two-dimensional QCD is studied from the point of view of existence of
multiple chirally noninvariant solutions to the mass-gap equation. The
ground-state solution is reproduced and an infinite set of replica solutions is
discovered for this equation using the WKB quantisation procedure.


title: Comment on the proper QCD string dynamics in a heavy-light system

abstract:
  The string correction to the inter-quark interaction at large distances is
derived using the field theory approach to a heavy-light quark-antiquark system
in the modified Fock-Schwinger gauge.


title:
Background Analysis around Q_(beta-beta) for 76Ge Double Beta Decay
  experiments, and Statistics at Low Count Rates

abstract:
  The background in the region of the Q-value for neutrinoless double beta
decay of 76Ge has been investigated by different methods: Simulation with GEANT
4 of the HEIDELBERG-MOSCOW experiment, analysis of other Ge double beta
experiments.Statistical features of the analysis at very low count rates are
discussed.


title: Primordial Lepton Family Asymmtries in Seesaw Model

abstract:
  In leptogenesis scenario, the decays of heavy Majorana neutrinos generate
lepton family asymmetries, $Y_e, Y_{\mu}$ and $Y_{\tau}$. They are sensitive to
CP violating phases in seesaw models. The time evolution of the lepton family
asymmetries are derived by solving Boltzmann equations. By taking a minimal
seesaw model, we show how each family asymmetry varies with a CP violating
phase. For instance, we find the case that the lepton asymmetry is dominated by
$Y_{\mu}$ or $Y_{\tau}$ depending on the choice of the CP violating phase. We
also find the case that the signs of lepton family asymmetries $Y_{\mu}$ and
$Y_{\tau}$ are opposite each other. Their absolute values can be larger than
the total lepton asymmetry and the baryon asymmetry may result from the
cancellation of the lepton family asymmetries.


title:
Comment on the narrow charmonium state of Belle at 3871.8 MeV as a
  deuson

abstract:
  It is pointed out that the narrow charmonium state at 3871.8 MeV reported by
the Belle collaboration is likely to be a $D\bar D^*$ deuteronlike meson-meson
state called a deuson. It was predicted near the $D\bar D^*$ threshold over 10
years ago. Its spin-parity would be 0-+ or 1++ and an important decay mode
should be via $D^0\bar D^{*0}$ to $D^0\bar D^0\pi^0$. Its width to that channel
should then be of the order 50 keV. Note: A more detailed update of this
unpublished note is in hep-ph/0402237.


title: Extrinsic CPT Violation in Neutrino Oscillations

abstract:
  In this talk, we investigate extrinsic CPT violation in neutrino oscillations
in matter with three flavors. Note that extrinsic CPT violation is different
from intrinsic CPT violation. Extrinsic CPT violation is one way of quantifying
matter effects, whereas intrinsic CPT violation would mean that the CPT
invariance theorem is not valid. We present analytical formulas for the
extrinsic CPT probability differences and discuss their implications for
long-baseline experiments and neutrino factory setups.


title:
A Linear Evolution for Non-Linear Dynamics and Correlations in Realistic
  Nuclei

abstract:
  A new approach to high energy evolution based on a linear equation for QCD
generating functional is developed. This approach opens a possibility for
systematic study of correlations inside targets, and, in particular, inside
realistic nuclei.
  Our results are presented as three new equations. The first one is a linear
equation for QCD generating functional (and for scattering amplitude) that sums
the 'fan' diagrams. For the amplitude this equation is equivalent to the
non-linear Balitsky-Kovchegov equation.
  The second equation is a generalization of the Balitsky-Kovchegov non-linear
equation to interactions with realistic nuclei. It includes a new correlation
parameter which incorporates, in a model dependent way, correlations inside the
nuclei.
  The third equation is a non - linear equation for QCD generating functional
(and for scattering amplitude) that in addition to the 'fan' diagrams sums the
Glauber-Mueller multiple rescatterings.


title: Relativistic Bound States

abstract:
  In this contribution, I will give a brief survey of present techniques to
treat the bound state problem in relativistic quantum field theories. In
particular, I will discuss the Bethe-Salpeter equation, various quasi-potential
equations, the Feynman-Schwinger representation, and similarity transformation
methods for Hamiltonian approaches in light-front quantization. Finally, I will
comment on a related similarity transformation in the usual equal-time
quantized theory.


title: Lorentz and CPT Tests in Matter and Antimatter

abstract:
  A review of recent theoretical work investigating tests of Lorentz and CPT
symmetry in atomic and particle systems is presented. A variety of tests in
matter and antimatter are discussed, including measurements of anomalous
magnetic moments in Penning traps, comparisons of atomic-clock transitions,
high-precision spectroscopic measurements of hydrogen and antihydrogen,
experiments with muons, experiments with mesons, and tests of Lorentz symmetry
with a spin-polarized torsion pendulum.


title: Tripartite Neutrino Mass Matrix

abstract:
  The 3 X 3 Majorana neutrino mass matrix is written as a sum of 3 terms, i.e.
M_nu = M_A + M_B + M_C, where M_A is proportional to the identity matrix and
M_B and M_C are invariant under different Z_3 transformations. This M_nu is
very suitable for understanding atmospheric and solar neutrino oscillations,
with sin^2 (2 theta_atm) and tan^2 (theta_sol) fixed at 1 and 0.5 respectively,
in excellent agreement with present data. It has in fact been proposed before,
but only as an ansatz. This paper uncovers its underlying symmetry, thus
allowing a complete theory of leptons and quarks to be constructed.


title:
Diffractive Higgs boson production at Tevatron and LHC: an experimental
  review

abstract:
  We discuss the different models of central diffractive production of the
Higgs boson at the Tevatron and the LHC. We also describe how the models can be
tested using diffractive production data being taken at the Tevatron. We
finally discuss the advantages of using diffractive events to reconstruct the
mass of the Higgs boson especially at the LHC.


title: BFKL Dynamics in Jet Evolution

abstract:
  We calculate $e^+e^- \to Q\bar{Q}(k) + anything in a certain momentum, k,
region for heavy quark-antiquark (Q\bar{Q})production. In our chosen region we
find that the number of heavy quark pairs produced is determined by BFKL
dynamics and the energy dependence of the number of pairs is given by $\alpha
p-1$ the hard pomeron intercept.


title: R Parity Violating Decays of the Gluino

abstract:
  Assuming the lightest supersymmetric particle is the gluino, we treat the
decays gluino->quark-antiquark-neutrino and gluino->gluon-neutrino. Such
couplings can be induced by the R parity violating quark-squark-lepton
interaction which can also be responsible for neutrino masses and mixings.
These R parity violating gluino decays have the same final state structure
(jets plus missing energy) as previously considered decays into
quark-antiquark-photino and gluon-gravitino but with significantly different
gluino lifetimes.


title: Z^* Resonances: Phenomenology and Models

abstract:
  We explore the phenomenology of, and models for, the Z^* resonances, the
lowest of which is now well established, and called the Theta. We provide an
overview of three models which have been proposed to explain its existence
and/or its small width, and point out other relevant predictions, and potential
problems, for each. The relation to what is known about KN scattering,
including possible resonance signals in other channels, is also discussed.


title: Electroweak High-Energy Scattering and the Chiral Anomaly

abstract:
  The effect of perturbative QCD interactions on the high energy scattering of
electroweak vector bosons, when the exchanged channel has pion quantum numbers,
is considered. The chiral anomaly is shown to appear in the couplings of
particular transverse momentum diagrams, producing an enhancement of the
scattering amplitude by a power of the energy. At $O(\alpha_s)$ a single large
transverse momentum gluon is involved and, within the transverse momentum
diagram framework, there is no cancelation. In higher orders, soft gluons,
carrying both normal and anomalous color parity, are also present.
  The manipulation of a transverse momentum cut-off to replace the ultra-violet
anomaly divergence by infra-red divergences that can lead to confinement and
chiral symmetry breaking is briefly discussed. Possible implications for
electroweak symmetry breaking are noted.


title: Analytic Invariant Charge in QCD

abstract:
  This paper gives an overview of recently developed model for the QCD analytic
invariant charge. Its underlying idea is to bring the analyticity condition,
which follows from the general principles of local Quantum Field Theory, in
perturbative approach to renormalization group (RG) method. The concrete
realization of the latter consists in explicit imposition of analyticity
requirement on the perturbative expansion of $\beta$ function for the strong
running coupling, with subsequent solution of the corresponding RG equation. In
turn, this allows one to avoid the known difficulties originated in
perturbative approximation of the RG functions. Ultimately, the proposed
approach results in qualitatively new properties of the QCD invariant charge.
The latter enables one to describe a wide range of the strong interaction
processes both of perturbative and intrinsically nonperturbative nature.


title: Reanalysis of QCD sum rules for nucleon with perturbative correction

abstract:
  A new analysis of baryon sum rules is done with modern values of parameters
and known perturbative corrections. The restriction for gluon and quark
condensates and the new value of nucleon coupling constant are found.


title: Holography, Entropy and Extra Dimensions

abstract:
  We show that higher dimensional models (brane worlds) in which the scale of
quantum gravity $M_*$ is much smaller than the apparent scale $M_P \sim
10^{19}$ GeV are in conflict with bounds arising from holography and black hole
entropy. The thermodynamic entropy of astrophysical black holes and sub-horizon
volumes during big bang nucleosynthesis exceed the relevant bounds unless $M_*
> 10^{(4-6)}$ TeV, so a hierarchy relative to the weak scale is unavoidable. We
discuss the implications for extra dimensions as well as holography.


title: Scalar Particles in Lattice QCD

abstract:
  We report a project to study scalar particles by lattice QCD simulations.
After a brief introduction of the current situation of lattice study of the
sigma meson, we describe our numerical simulations of scalar mesons, $\sigma$
and $\kappa$. We observe a low sigma mass, $m_\pi<m_\sigma\le m_\rho$, for
which the disconnected diagram plays an important role. For the kappa meson, we
obtain higher mass than the experimental value, i.e., $m_\kappa\sim 2m_{K^*}$.


title:
Radiative muon (pion) pair production in high energy electron-positron
  annihilation (the case of small invariant pair mass)

abstract:
  The process of the muon (pion) pair production with small invariant mass in
the electron--positron high--energy annihilation, accompanied by emission of
hard photon at large angles, is considered. We find that the Drell--Yan picture
for differential cross section is valid in the charge--even experimental
set--up. Radiative corrections both for electron block and for final state
block are taken into account.


title: Hybrid Mesons from the Lattice

abstract:
  I review lattice QCD results for hybrid mesons, including a discussion of
their hadronic decays.


title: Structure of baryons in a relativistic quark model

abstract:
  Baryonic excitation spectra, electroweak and strong decay properties are
discussed within a relativistically covariant constituent quark model based on
the instantaneous approximation to the three-body Bethe-Salpeter equation.


title:
Curvaton Potential Terms, Scale-Dependent Perturbation Spectra and
  Chaotic Initial Conditions

abstract:
  The curvaton scenario predicts an almost scale-invariant spectrum of
perturbations in most inflation models. We consider the possibility that
renormalisable phi^4 or Planck scale-suppressed non-renormalisable curvaton
potential terms may result in an observable deviation from scale-invariance. We
show that if the curvaton initially has a large amplitude and if the total
number of e-foldings of inflation is less than about 300 then a running blue
perturbation spectrum with an observable deviation from scale-invariance is
likely. D-term inflation is considered as an example with a potentially low
total number of e-foldings of inflation. A secondary role for the curvaton, in
which it drives a period of chaotic inflation leading to D-term or other flat
potential inflation from an initially chaotic state, is suggested.


title:
Semileptonic decays of polarised top quarks: V + A admixture and QCD
  corrections

abstract:
  The semileptonic decays of polarised top quarks are analysed for a general
chirality-conserving tbW vertex. We calculate double differential distributions
for the charged lepton and the neutrino to order \alpha_s in the QCD coupling.
We present these QCD corrections in terms of compact parameterisations that
should be useful for the future investigation of the structure of the top decay
vertex on the basis of large data samples.


title: Flavour SU(3) Symmetry in Charmless B Decays

abstract:
  QCD sum rules are used to estimate the flavour SU(3)-symmetry violation in
two-body B decays to pions and kaons. In the factorizable amplitudes the
SU(3)-violation manifests itself in the ratio of the decay constants f_K/f_pi
and in the differences between the B->K, B_s->K and B->pi form factors. These
effects are calculated from the QCD two-point and light-cone sum rules,
respectively, in terms of the strange quark mass and the ratio of the strange
and nonstrange quark-condensate densities. Importantly, QCD sum rules predict
that SU(3) breaking in the heavy-to-light form factors can be substantial and
does not vanish in the heavy-quark mass limit. Furthermore, we investigate the
strange-quark mass dependence of nonfactorizable effects in the B->K pi decay
amplitudes. Taking into account these effects we estimate the accuracy of
several SU(3)-symmetry relations between charmless B-decay amplitudes.


title:
$\bar B^0\to \phi K_S$ and $\bar K^{*0}\gamma$ CP Asymmetries from
  Supersymmetric Right-handed Flavor Mixing: Implications for Heavy Quark
  Phenomenology

abstract:
  Two recent experimental developments, when combined, may have far reaching
implications. $S_{\phi K_S} < 0$, if confirmed, would imply large $s$-$b$
mixing, a new CP phase, and right-handed dynamics. Large $\Delta m_{B_s}$ would
be likely, making the $B_s$ program at hadron machines difficult.
Reconstruction of $B$ vertex from $K_S$ at B factories, as shown by BaBar's
first measurement of $S_{K_S\pi^0}$, makes $S_{K_S\pi^0\gamma}$ in $\bar B\to
\bar K^{*0}\gamma$ accessible. This would be a boon for B factory upgrades.
Supersymmetric Abelian flavor symmetry, independently motivated, can realize
all of this with a light $\widetilde{sb}_1$ squark. B factory and collider
studies of flavor, CP and SUSY may not be what we had expected.


title: LSND anomaly from CPT violation in four-neutrino models

abstract:
  The LSND signal for \bar\nu_\mu to \bar\nu_e oscillations has prompted
supposition that there may be a fourth light neutrino or that CPT is violated.
Neither explanation provides a good fit to all existing neutrino data. We
examine the even more speculative possibility that a four-neutrino model with
CPT violation can explain the LSND effect and remain consistent with all other
data. We find that models with a 3+1 mass structure in the neutrino sector are
viable; a 2+2 structure is permitted only in the antineutrino sector.


title: Lorentz and CPT Violation in the Neutrino Sector

abstract:
  We consider neutrino oscillations in the minimal Standard-Model Extension
describing general Lorentz and CPT violation. Among the models without neutrino
mass differences is one with two degrees of freedom that reproduces most major
observed features of neutrino behavior.


title:
Optimal Renormalization-Group Improvement of Two Radiatively-Broken
  Gauge Theories

abstract:
  In the absence of a tree-level scalar-field mass, renormalization-group (RG)
methods permit the explicit summation of leading-logarithm contributions to all
orders of the perturbative series for the effective-potential functions
utilized in radiative symmetry breaking. For scalar-field electrodynamics, such
a summation of leading logarithm contributions leads to upper bounds on the
magnitudes of both gauge and scalar-field coupling constants, and suggests the
possibility of an additional phase of spontaneous symmetry breaking
characterized by a scalar-field mass comparable to that of the theory's gauge
boson. For radiatively-broken electroweak symmetry, the all-orders summation of
leading logarithm terms involving the dominant three couplings (quartic
scalar-field, t-quark Yukawa, and QCD) contributing to standard-model radiative
corrections leads to an RG-improved potential characterized by a 216 GeV Higgs
boson mass. Upon incorporation of electroweak gauge couplants we find that the
predicted Higgs mass increases to 218 GeV. The potential is also characterized
by a quartic scalar-field coupling over five times larger than that anticipated
for an equivalent Higgs mass obtained via conventional spontaneous symmetry
breaking, leading to a concomitant enhancement of processes (such as $W^+ W^-
\to ZZ$) sensitive to this coupling. Moreover, if the QCD coupling constant is
taken to be sufficiently strong, the tree potential's local minimum at $\phi =
0$ is shown to be restored for the summation of leading logarithm corrections.
Thus if QCD exhibits a two-phase structure similar to that of $N = 1$
supersymmetric Yang-Mills theory, the weaker asymptotically-free phase of QCD
may be selected by the large logarithm behaviour of the RG-improved effective
potential for radiatively broken electroweak symmetry.


title: Heavy-quark recombination in Z^0 decay

abstract:
  We briefly review the recent advances of heavy-quark recombination mechanism.
This mechanism predicts a class of power-suppressed 3-jet events in $Z^0$
decay, such as $b\bar{b}q$ and $b\bar{b}\bar{q}$. Furthermore, heavy quark
fragmentation function also receives a contribution from this mechanism. Some
light can be shed on the scaling of the maximum of the fragmentation function
for S-wave heavy hadrons. We finally comment on a new variant of this mechanism
which has important impact on the precision electroweak physics.


title: Spectator interactions and factorization in B -> pi ell nu decay

abstract:
  We investigate the factorization of different momentum modes that appear in
matrix elements for exclusive B meson decays into light energetic particles for
the specific case of B -> pi form factors at large pion recoil. We first
integrate out hard modes with virtualities of order m_b^2 (m_b being the heavy
quark mass), and then hard-collinear modes with virtualities m_b Lambda (Lambda
being the strong interaction scale). The resulting effective theory contains
soft and collinear fields with virtualities Lambda^2. We prove a previously
conjectured factorization formula for B -> pi form factors in the heavy quark
limit to all orders in alpha_s, paying particular attention to `endpoint
singularities' that might have appeared in hard spectator interactions.


title: Dilepton Transverse Momentum in the Color Dipole Approach

abstract:
  We investigate the Drell-Yan transverse momentum distribution in the
framework of the color dipole approach. Special attention is paid to parton
saturation effects at high energies. Predictions at LHC energies ($\sqrt{s}=14$
TeV) are given and extrapolated down to ISR energies ($\sqrt{s}=62$ GeV).
Unitarity corrections are implemented through the multiple scattering
Glauber-Mueller approach and are compared with predictions of the BGBK
saturation model.


title:
CP violating SUSY effects in Penguin dominated modes B -> PHI K and B ->
  PHI K*

abstract:
  Recent measurement of time dependent asymmetries in $B \to \phi K$ are
indicative of a new source of CP violation. We examine squark mixing in SUSY as
this new source, and using QCD improved factorization method to describe $B \to
\phi K $ decay, find the allowed range of parameter space for $\rho$ and $\psi
$, the magnitude and phase of the down type LR(RL) squark mixing parameter
$\delta^{bs}_{LR(RL)}$. We then study $B \to \phi K^{*}$ and calculate the
expected CP asymmetries in the same range of parameter space. We find that this
asymmetry is in the range 15% to $20% $ for acceptable value of $B \to phi
K^{*}$ branching ratio. We also predict the helicity dependent CP asymmetries
in the same parameter space.


title: Phase-space density in heavy-ion collisions revisited

abstract:
  We derive the phase space density of bosons from a general boson
interferometry formula.
  We find that the phase space density is connected with the two-particles and
the single particle density distribution functions. If the boson density is
large, the two particles density distribution function can not be expressed as
a product of two single particle density distributions. However, if the boson
density is so small that two particles density distribution function can be
expressed as a product of two single particle density distributions, then
Bertsch's formula is recovered. For a Gaussian model, the effects of
multi-particles Bose-Einstein correlations on the mean phase space density are
studied.


title: Covariant Classification Scheme of Hadrons and Chiral States

abstract:
  The essential points and physical backgrounds of the covariant
level-classification scheme, recently proposed by us, are reviewed: In this
scheme the general composite hadrons are classified as the multiplets with the
U(12)SF * O(3,1) symmetry, where U(12)SF supset U(4)D.S. * SU(3)F, and U(4)D.S.
is a homogeneous Lorentz transformation group for Dirac spinors. This symmetry
predicts the existence of new type of chiral mesons and baryons out of the
conventional level classification scheme. The sigma nonet is a typical example
of chiralons to be assigned to the q bar q relativistic S-wave state.


title: Properties of sigma and kappa Production Amplitudes

abstract:
  Our method of analysis, which led to existence of sigma and kappa mesons, is
reviewed and examined from a viewpoint of general S-matrix. It is shown that
the method is consistent with the constraints from chiral symmetry and
unitarity. Accordingly the long-believed common analyses of pipi (Kpi)
scattering and production processes, based on elastic unitarity, prove to lose
its theoretical base. The observed phase motion by 180 degrees of sigma shows
also the validity of our method.


title:
Relation between Scattering and Production Amplitudes -- Case of sigma
  and kappa in pipi and Kpi Systems --

abstract:
  In our talk at Nihon university symposium, we have argued that the pipi / Kpi
production amplitudes F generally have different structures from those of the
pipi / Kpi scattering amplitudes T from a viewpoint of generalized S matrix on
the right bases, reflecting the quark-physical picture of strong interactions,
and that F should be analyzed independently from T. Here we discuss the
miscellaneous topics related with this argument: The conventional analyses by K
matrix method, which necessarily lead to the common phases and structures
through both T and F, are based on improper application of elastic unitarity to
the production processes. Recent criticisms on the method of analyses of J/psi
-> omega pipi and D+ -> K- pi+ pi+, which led to the existence of sigma and
kappa, respectively, are also based on improper application of elastic
unitarity.


title: Ground State Baryons in Covariant Level-Classification Scheme

abstract:
  In the covariant level-classification scheme of hadrons based on U(12)SF *
O(3,1)L symmetry, the ground state baryons and antibaryons are assigned to the
(12 * 12 * 12)Sym = 364-multiplet in the spin-flavor U(12)SF symmetry. This
multiplet includes, in addition to the ordinary 56-multiplet of the static
SU(6)SF, the extra chiral 56' and 70-multiplets, called "chiralons," which are
expected to exist with masses in 1 -- 2 GeV region. Their electro-magnetic
properties, magnetic moments and radiative decay amplitudes, are investigated.
A longstanding puzzle, that the predicted value of the width Gamma(Delta -> N
gamma) by the conventional treatment is inconsistently small with the
experimental one, may be solved by the mixing effect of 56-states with the
chiral 56'-states.


title: The massless two-loop two-point function

abstract:
  We consider the massless two-loop two-point function with arbitrary powers of
the propagators and derive a representation, from which we can obtain the
Laurent expansion to any desired order in the dimensional regularization
parameter eps. As a side product, we show that in the Laurent expansion of the
two-loop integral only rational numbers and multiple zeta values occur. Our
method of calculation obtains the two-loop integral as a convolution product of
two primitive one-loop integrals. We comment on the generalization of this
product structure to higher loop integrals.


title:
The radiative return at phi- and B-factories: FSR at next-to-leading
  order

abstract:
  The measurement of the pion form factor and, more generally, of the cross
section for electron--positron annihilation into hadrons through the radiative
return has become an important task for high luminosity colliders such as the
$\Phi$- or $B$-meson factories. For detailed understanding and analysis of this
reaction, the construction of a Monte Carlo program, PHOKHARA, has been
undertaken. Version 2.0 was based on a next-to-leading order (NLO) treatment of
the corrections from initial-state radiation (ISR). In the present paper a
further extension of PHOKHARA (version 3.0) is described, which incorporates
NLO corrections to final-state radiation (FSR). The impact of combined ISR and
FSR on various distributions is investigated and methods are presented, which
will allow the extraction of the form factor, and even give access to inclusive
photon emission due to FSR. The dependence of the results on the model for FSR
is discussed and the impact of this contribution on the anomalous magnetic
moment of the muon is evaluated.


title: Photoproduction of Theta baryon from the neutron

abstract:
  We study photoproduction reactions for Theta^+, which was recently observed
as a candidate of an exotic five quark state uudd(bar s). We employ effective
lagrangian interactions in the linear and non-linear formalism of chiral
symmetry and investigate two cases of spin and parity of Theta^+, J^P = 1/2^+
and 1/2^-. We calculate cross sections and discuss possibilities to
discriminate one from the other.


title: The present situation in the determination of $\alpha_s$

abstract:
  This note reviews the latest measurements of $\alpha_s$ from event shapes in
$e^+e^-$ annihilation at LEP1 and LEP2. A critical review of different methods
to extract \as is offered.


title: From Color Glass to Color Dipoles in high-energy onium--onium scattering

abstract:
  Within the Color Glass formalism, we construct the wavefunction of a high
energy onium in the BFKL and large-N_c approximations, and demonstrate the
equivalence with the corresponding result in the Color Dipole picture. We
propose a simple factorization formula for the elastic scattering between two
non-saturated ``color glasses'' in the center-of-mass frame. This is valid up
to energies which are high enough to allow for a study of the onset of
unitarization via multiple pomeron exchanges. When applied to the high energy
onium-onium scattering, this formula reduces to the Glauber-like scattering
between two systems of dipoles, in complete agreement with the dipole picture.


title: Automated resummation of jet observables in QCD

abstract:
  We present a master formula, with applicability conditions, which allows us
to automate the resummation of infrared and collinear logarithms appearing in
distributions of jet observables in QCD at next-to-leading logarithmic
accuracy.


title:
Study of Quartic Boson Vertices at Photon Colliders in the Standard
  Model and Beyond

abstract:
  The production of several vector bosons in $\gamma\gamma$-interactions is the
best place to search directly for any anomalous behavior of triple and quartic
couplings. A few anomalous quartic boson operators are considered in the paper.
A high precision of anomalous effects can be achieved by calculation of the
lowest order electroweak corrections: one-loop corrections, real photon and
$Z$-boson emission.


title: On the structure of the scalar and D mesons

abstract:
  The ${q}\bar{q}$ spectrum is studied within a chiral constituent quark model.
It provides with a good fit of the available experimental data from light
(vector and pseudoscalar) to heavy mesons. The new $D$ states measured at
different factories are studied. The $0^{++}$ light mesons are analyzed as
$q\bar q$ pairs or tetraquark structures.


title: Factorization and Sudakov Resummation in B -> gamma l nu

abstract:
  We apply Soft-Collinear Effective Theory to prove at leading power in
Lambda_QCD/m_b a factorization formula for the radiative leptonic decay B ->
gamma l nu. Large logarithms entering the hard-scattering kernel are
systematically resummed by a two-step perturbative matching procedure.


title: Pomeron fan diagrams with an infrared cutoff and running coupling

abstract:
  By direct numerical calculations the influence of a physically relevant
infrared cutoff and running coupling on the gluon density and structure
function of a large nucleus is studied in the perturbative QCD approach. It is
found that the infrared cutoff changes the solutions very little. Running of
the coupling produces a bigger change, considerably lowering both the
saturation momentum and values of the structure functions.


title: Mein Ruf to Search New Strange $a_2^s(1520)$-meson

abstract:
  In this note we propose to search new strange $a_2^s(1520)$-meson which is a
strange partner of the $a_2(1311)$-meson observed in a three-pion system.


title: Are $\Theta^+$ and the Roper resonance diquark-diquark-antiquark states?

abstract:
  We consider a $[ud]^2\bar{s}$ current in the QCD sum rule framework to study
the mass of the recently observed pentaquark state $\Theta^+(1540)$, obtaining
good agreement with the experimental value. We also study the mass of the
pentaquark $[ud]^2\bar{d}$. Our results are compatible with the interpretation
of the $[ud]^2\bar{d}$ state as being the Roper resonance N(1440), as suggested
by Jaffe and Wilczek.


title:
Kaluza-Klein Picture of the World and Global Solution of the Spectral
  Problem

abstract:
  We suggest that Kaluza-Klein idea may provide the global solution of the
spectral problem in hadronic spectroscopy.


title: Contributions of gluon recombination to saturation phenomena

abstract:
  Parton distributions in the small $x$ region are numerically predicted by
using a modified DGLAP equation with the GRV-like input distributions. We find
that gluon recombination at twist-4 level obviously suppresses the rapid growth
of parton densities with $x$ decrease. We show that before the saturation scale
$Q^2_s$ is reached, saturation and partial saturation appear in the small $x$
behavior of parton distributions in nucleus and free proton, respectively. The
antishadowing contributions to the saturation phenomena are also discussed.


title:
Dirac equation in the confining SU(3)-Yang-Mills field and relativistic
  effects in charmonium spectrum

abstract:
  The recently obtained solutions of the Dirac equation in the confining
SU(3)-Yang-Mills field in Minkowski spacetime are applied to describe the
energy spectrum of charmonium. The nonrelativistic limit is considered for the
relativistic effects to be estimated in a self-consistent way and it is shown
that the given effects could be extremely important for both the energy
spectrum and the confinement mechanism.


title:
Infrared regularization of baryon chiral perturbation theory
  reformulated

abstract:
  We formulate the infrared regularization of Becher and Leutwyler in a form
analogous to our recently proposed extended on-mass-shell renormalization. In
our formulation, IR regularization can be applied straightforwardly to
multi-loop diagrams with an arbitrary number of particles with arbitrary
masses.


title:
Dirac equation in the confining SU(3)-Yang-Mills field and the
  relativistic effects in quarkonia spectra

abstract:
  The recently obtained solutions of Dirac equation in the confining
SU(3)-Yang-Mills field in Minkowski spacetime are applied to describe the
energy spectra of quarkonia (charmonium and bottomonium). The nonrelativistic
limit is considered for the relativistic effects to be estimated in a
self-consistent way and it is shown that the given effects are extremely
important for both the energy spectra and the confinement mechanism.


title: The Resummed Photon Spectrum in Radiative Upsilon Decays (And More)

abstract:
  In this talk I present the results of two calculations that make use of
Non-Relativistic QCD and the newly developed Soft-Collinear Effective Theory.
The first process considered is inclusive radiative $\Upsilon$ decay. The
second process considered is the leading color-octet contribution to $e^+ e^-
\to J/\psi + X$.


title:
O(10) kinks: clash of symmetries on the brane and the gauge hierarchy
  problem

abstract:
  We study kink or domain wall solutions in O(10) Higgs models in the context
of the ``clash of symmetries'' mechanism developed by Davidson, Toner, Volkas
and Wali and, independently, by Pogosian and Vachaspati. We show that kink
configurations employing Higgs fields in the 45 (the adjoint representation) of
O(10) break up into three classes: those that at finite distances from the wall
respect a U(5) subgroup of SO(10), and two others that respect the smaller
subgroups U(3) x U(2) and U(4) x U(1). These smaller subgroups arise from the
clash of symmetries mechanism: they are the intersections of two differently
embedded U(5) subgroups of SO(10), the latter being the symmetries respected in
asymptotia on opposite sides of the domain wall. The existence of the SO(10) ->
U(3) x U(2) = SU(3) x SU(2) x U(1) x U(1)' = G_{SM} x U(1)' class advances the
search for a realistic brane world model wherein some of the required symmetry
breaking is achieved via the clash of symmetries rather than the conventional
mechanism. At the centres of the walls, the unbroken symmetries are enhanced.
In the U(3) x U(2) case, the symmetry is O(6) x U(2), which is closely related
to the Pati-Salam-like SU(4) x SU(2) x U(1) group. If our universe is a brane
located at the centre of such a wall, then we see the O(10) symmetry as being
strongly broken to SU(4) x SU(2) x U(1). Interestingly, if the brane-world
degrees of freedom enjoy a slight leakage off the wall, then an additional
symmetry breakdown to U(3) x U(2) = G_{SM} x U(1)' is effectively induced on
the brane. This provides a possible framework within which to address at least
part of a gauge hierarchy problem: O(10) is strongly broken to SU(4) x SU(2) x
U(1), then more weakly to G_{SM} x U(1)' depending on the amount of leakage off
the brane. We also comment on kinks employing the 10 and 54 of O(10).


title: Status of CCFM - unintegrated gluon densities

abstract:
  New fits of the unintegrated gluon density obtained from CCFM evolution to
HERA $F_2(x,Q^2)$ data are presented. Also predictions of the unintegrated
gluon density of the real photon are presented.


title:
Full order alpha electroweak corrections to double Higgs-strahlung at
  the linear collider

abstract:
  We present the full order alpha electroweak radiative corrections to the
double Higgs-strahlung process e+e- --> ZHH. The computation is performed with
the help of GRACE-loop. After subtraction of the initial state QED radiative
corrections, we find that the genuine weak corrections in the $\alpha$-scheme
are small for Higgs masses and energies where this cross section is largest and
is most likely to be studied. These corrections decrease with increasing
energies attaining about $\sim -10%$ at $\sqrt{s}=1.5$TeV. The full order alpha
correction on the other hand is quite large at threshold but small at energies
around the peak. We also study changes in the shape of the invariant mass of
the Higgs pair which has been shown to be a good discriminating variable for
the measurement of the triple Higgs vertex in this reaction.


title: Two-photon decays of pi^0, eta and eta-prime

abstract:
  We investigate the decays of pi^0, eta and eta-prime into two photons in an
effective U(3) chiral Lagrangian approach without employing large N_c
arguments. Tree level and one-loop contributions from the anomalous
Wess-Zumino-Witten Lagrangian are calculated and the importance of
eta--eta-prime mixing is discussed. Unitarity corrections beyond one-loop play
an important role for the decays with off-shell photons and are included by
employing a coupled channel Bethe-Salpeter equation which satisfies unitarity
constraints and generates vector-mesons from composed states of two
pseudoscalar mesons.


title: The B -> pi K Puzzle and its Relation to Rare B and K Decays

abstract:
  The Standard-Model interpretation of the ratios of charged and neutral B-> pi
K rates, R_c and R_n, respectively, points towards a puzzling picture. Since
these observables are affected significantly by colour-allowed electroweak (EW)
penguins, this ``B -> pi K puzzle'' could be a manifestation of new physics in
the EW penguin sector. Performing the analysis in the R_n-R_c plane, which is
very suitable for monitoring various effects, we demonstrate that we may, in
fact, move straightforwardly to the experimental region in this plane through
an enhancement of the relevant EW penguin parameter q. We derive analytical
bounds for q in terms of a quantity L, that measures the violation of the
Lipkin sum rule, and point out that strong phases around 90 deg are favoured by
the data, in contrast to QCD factorisation. The B -> pi K modes imply a
correlation between q and the angle gamma that in the limit of negligible
rescattering effects and colour suppressed EW penguins depends only on the
value of L. Concentrating on a minimal flavour-violating new-physics scenario
with enhanced Z^0 penguins, we find that the current experimental values on
  B -> X_s mu^+ mu^- require roughly L <= 1.8. As the B -> pi K data give L =
5.7 +- 2.4, L has either to move to smaller values once the B -> pi K data
improve or new sources of flavour and CP violation are needed. In turn, the
enhanced values of L seen in the B -> pi K data could be accompanied by
enhanced branching ratios for rare decays. Most interesting turns out to be the
correlation between the B -> pi K modes and BR(K^+ -> pi^+ nu nu), with the
latter depending approximately on a single ``scaling'' variable \bar L= L
(|V_{ub}/V_{cb}|/0.086)^2.3.


title: Antineutrinos from Earth: A reference model and its uncertainties

abstract:
  We predict geoneutrino fluxes in a reference model based on a detailed
description of Earth's crust and mantle and using the best available
information on the abundances of uranium, thorium, and potassium inside Earth's
layers. We estimate the uncertainties of fluxes corresponding to the
uncertainties of the element abundances. In addition to distance integrated
fluxes, we also provide the differential fluxes as a function of distance from
several sites of experimental interest. Event yields at several locations are
estimated and their dependence on the neutrino oscillation parameters is
discussed. At Kamioka we predict N(U+Th)=35 +- 6 events for 10^{32} proton yr
and 100% efficiency assuming sin^2(2theta)=0.863 and delta m^2 = 7.3 X 10^{-5}
eV^2. The maximal prediction is 55 events, obtained in a model with fully
radiogenic production of the terrestrial heat flow.


title: Flavour violation with a single generation

abstract:
  We calculate probabilities of flavour violating processes mediated by
Kalutza-Klein modes of gauge bosons in a model where three generations of the
Standard Model fermions arise from a single generation in (5+1) dimensions. We
discuss a distinctive feature of the model: while the processes in which the
generation number $G$ changes are strongly suppressed, the model is constrained
by those with $\Delta G=0$, for instance $K\to \mu ^\pm e^\mp$. The bound on
the size of the extra dimensions is $1/R \gtrsim 64$ TeV.


title: JaxoDraw: A graphical user interface for drawing Feynman diagrams

abstract:
  JaxoDraw is a Feynman graph plotting tool written in Java. It has a complete
graphical user interface that allows all actions to be carried out via mouse
click-and-drag operations in a WYSIWYG fashion. Graphs may be exported to
postscript/EPS format and can be saved in XML files to be used in later
sessions. One of the main features of JaxoDraw is the possibility to produce
LaTeX code that may be used to generate graphics output, thus combining the
powers of TeX/LaTeX with those of a modern day drawing program. With JaxoDraw
it becomes possible to draw even complicated Feynman diagrams with just a few
mouse clicks, without the knowledge of any programming language.


title:
Three heavy jet events at hadron colliders as a sensitive probe of the
  Higgs sector

abstract:
  Assuming that a non-standard neutral Higgs with an enhanced Yukawa coupling
to a bottom quark is observed at future hadron experiments, we propose a method
for a better understanding of the Higgs sector. Our procedure is based on
"counting" the number of events with heavy jets (where "heavy" stands for a c
or b jet) versus b jets, in the final state of processes in which the Higgs is
produced in association with a single high p_T c or b jet. We show that an
observed signal of the type proposed, at either the Tevatron or the LHC, will
rule out the popular two Higgs doublet model of type II as well as its
supersymmetric version - the Minimal Supersymmetric Standard Model (MSSM), and
may provide new evidence in favor of some more exotic multi Higgs scenarios. As
an example, we show that in a version of a two Higgs doublet model which
naturally accounts for the large mass of the top quark, our signal can be
easily detected at the LHC within that framework. We also find that such a
signal may be observable at the upgraded Tevatron RunIII, if the neutral Higgs
in this model has a mass around 100 GeV and \tan\beta > 50 and if the
efficiency for distinguishing a c jet from a light jet will reach the level of
50%.


title:
Regulariztion dependence of S=0 and S=-1 meson-baryon system in the
  chiral unitary model

abstract:
  We investigate the dependence of s-wave meson-baryon scattering amplitudes on
different regularizations within the framework of the chiral unitary model. We
employ two different regularization schemes, i.e. dimensional and form-factor
regulariaztions to tame the divergences in the model. We also study the
analytic structures of T-matrices, using those regularization schemes. We find
that while the form-factor regularizaion produces almost the same results as
the dimensional regularization did, the on-shell approximation is to some
extent limited in the case of the form-factor regularization. Having chosen
parameters properly, we show that the regularization dependences can be
minimized.


title:
Photon polarization with anomalous right-handed top couplings in $B\to
  K_{res}\gamma$

abstract:
  The effect of anomalous right-handed top couplings on the photon polarization
in $B\to K_{\rm res}\gamma$ is investigated. It is recently reported that the
photon polarization can be measured through the up-down asymmetry of the photon
direction relative to the subsequent $K_{\rm res}$ decay plane. We find that
the anomalous couplings can severely affect the photon polarization without
spoiling the well measured branching ratio of $B\to X_s\gamma$. Different
features from other scenarios are also discussed.


title: Anomalous specific heat in high-density QED and QCD

abstract:
  Long-range quasi-static gauge-boson interactions lead to anomalous
(non-Fermi-liquid) behavior of the specific heat in the low-temperature limit
of an electron or quark gas with a leading $T\ln T^{-1}$ term. We obtain
perturbative results beyond the leading log approximation and find that
dynamical screening gives rise to a low-temperature series involving also
anomalous fractional powers $T^{(3+2n)/3}$. We determine their coefficients in
perturbation theory up to and including order $T^{7/3}$ and compare with exact
numerical results obtained in the large-$N_f$ limit of QED and QCD.


title: A proposal of neutrino mass formula

abstract:
  An explicit mass formula is proposed for three active neutrinos and their
heavy sterile (righthanded) counterparts in the framework of seesaw mechanism.
The formula correlates reasonably the experimental estimates for the solar
$\Delta m^2_{12}$ and atmospheric $\Delta m^2_{32}$ in the case of hierarchical
spectrum $m^2_1 \ll m^2_2 \ll m^2_3 $ of active neutrinos. The lightest heavy
neutrino is predicted to be $O(10^5)$ times lighter than the heaviest. An
efficient mass formula, proposed previously for charged leptons, is recalled
and coordinated with the new mass formula for neutrinos.


title:
Electroweak Gauge Theories and Alternative Theories at a Future Linear
  e+e- Collider

abstract:
  The measurement of Standard Model processes tests the validity of the model
at a given scale and is simultaneously sensitive to new physics through loop
effects or interference with the Standard Model amplitudes. A variety of
studies has been done to see what a linear collider in the energy range MZ <
sqrt{s} < 1 TeV can offer. The work that has been done within the ECFA/DESY
workshop on linear colliders is reviewed, especially what was not included in
the TESLA TDR.


title: Direct Searches of New Physics at CLIC

abstract:
  The multi-TeV e+e- collider CLIC may allow for the direct study of new
neutral gauge bosons or Kaluza-Klein states in the TeV range. We discuss some
of the experimental aspects for the study of such resonances. Further we
discuss briefly the effects of soft branes in scenarios with Large Extra
Dimensions, and the production of Black Holes at CLIC.


title:
Mearsurement of $\alpha_s$ and the $\beta$ function with the DELPHI
  detector at LEP

abstract:
  Event shape distributions in $e^+e^-$ annihilation are determined from the
DELPHI data taken between 183 and 207\gev. From these the strong coupling
$\alpha_s$ is extracted with several techniques. Together with the results from
other LEP2 energies and at about $m_Z$ this allows both, a combined measurement
of $\alpha_s$ and a test of the scale dependence of the strong interaction.
Alternatively the renormalisation group invariant (RGI) perturbation theory is
applied to measure the $\beta$ function of strong interaction. The results are
good agreement with the QCD expectation and allow to exclude the existence of
light gluinos with a mass below 30\gev in a model independent way.


title: Status of Neutrino Masses and Mixing

abstract:
  The experimental evidences in favor of oscillations of solar (and KamLAND)
and atmospheric (and K2K) neutrinos are briefly reviewed and accommodated in
the framework of three-neutrino mixing. The implications for the values of
neutrino masses are discussed and the bounds on the absolute scale of neutrino
masses from Tritium beta-decay and cosmological data are reviewed. Finally, we
discuss the implications of three-neutrino mixing for neutrinoless double-beta
decay.


title: Lorentz and CPT Violation in Neutrinos

abstract:
  A general formalism is presented for violations of Lorentz and CPT symmetry
in the neutrino sector. The effective hamiltonian for neutrino propagation in
the presence of Lorentz and CPT violation is derived, and its properties are
studied. Possible definitive signals in existing and future
neutrino-oscillation experiments are discussed. Among the predictions are
direction-dependent effects, including neutrino-antineutrino mixing, sidereal
and annual variations, and compass asymmetries. Other consequences of Lorentz
and CPT violation involve unconventional energy dependences in oscillation
lengths and mixing angles. A variety of simple models both with and without
neutrino masses are developed to illustrate key physical effects. The
attainable sensitivities to coefficients for Lorentz violation in the
Standard-Model Extension are estimated for various types of experiments. Many
experiments have potential sensitivity to Planck-suppressed effects, comparable
to the best tests in other sectors. The lack of existing experimental
constraints, the wide range of available coefficient space, and the variety of
novel effects imply that some or perhaps even all of the existing data on
neutrino oscillations might be due to Lorentz and CPT violation.


title: Pseudogap of Color Superconductivity in Heated Quark Matter

abstract:
  We show that the pseudogap of the quark density of states is formed in hot
quark matter as a precursory phenomenon of the color superconductivity on the
basis of a low-energy effective theory. We clarify that the decaying process of
quarks near Fermi surface to a hole and the diquark soft mode (qq)_{soft} is
responsible for the formation of the pseudogap. Our result suggests that the
pseudogap is a universal phenomenon in strong coupling superconductors.


title: Probing Supersymmetry with Neutral Current Scattering Experiments

abstract:
  We compute the supersymmetric contributions to the weak charges of the
electron and proton in the framework of Minimal Supersymmetric Standard Model.
We also consider the ratio of neutral current to charged current cross
sections, R_nu and R_nubar at nu (nubar)-nucleus deep inelastic scattering, and
compare the supersymmetric corrections with the deviations of these quantities
from the Standard Model predictions implied by the recent NuTeV measurement.


title: Critical analysis of derivative dispersion relations at high energies

abstract:
  We discuss some formal and fundamental aspects related with the replacement
of integral dispersion relations by derivative forms, and their practical uses
in high energy elastic hadron scattering, in particular $pp$ and $\bar{p}p$
scattering. Starting with integral relations with one subtraction and
considering parametrizations for the total cross sections belonging to the
class of entire functions in the logarithm of the energy, a series of results
is deduced and our main conclusions are the following: (1) except for the
subtraction constant, the derivative forms do not depend on any additional free
parameter; (2) the only approximation in going from integral to derivative
relations (at high energies) concerns to assume as zero the lower limit in the
integral form; (3) the previous approximation and the subtraction constant
affect the fit results at both low and high energies and therefore, the
subtraction constant can not be disregarded; (4) from a practical point of
view, for single-pole Pomeron and secondary reggeons parametrizations and
center-of-mass energies above 5 GeV, the derivative relations with the
subtraction constant as a free fit parameter are completely equivalent to the
integral forms with finite (non-zero) lower limit. A detailed review on the
conditions of validity and assumptions related with the replacement of integral
by derivative relations is also presented and discussed.


title:
Indirect Evidence for the Supersymmetric Nature of Dark Matter from the
  Combined Data on Galactic Positrons, Antiprotons and Gamma Rays

abstract:
  Two new observations have strengthened the case for the supersymmetric nature
of the Cold Dark Matter component in our universe: First, it was shown that new
data on the nuclear abundance, B/C - and 10Be/9Be ratios constrain the
diffusion parameters in Galactic Models so strongly, that they lead to a clear
deficiency in the production of diffuse hard gamma rays, antiprotons and hard
positrons, if no anomalous sources or anomalous energy dependence of the
diffusion coefficients are postulated. Second, from the precise relic density
measurement by WMAP the WIMP annihilation cross section can be determined in a
model independent way. If the WIMPS are postulated to be the neutralinos of
Supersymmetry, then only a limited region of parameter space matches this
annihilation cross section. It is shown that the resulting positrons,
antiprotons and gamma rays from the neutralino annihilation (mainly into
b-quarks) provide the correct shape and magnitude for the missing fluxes in the
Galactic Models.
  The probability of a global fit to the galactic spectra of diffuse gamma
rays, positrons and antiprotons improves from about 10^{-8} to 0.5, if Dark
Matter, as predicted by Supersymmetry,is taken into account. This corresponds
to about 6 sigma evidence for the supersymmetric nature of Dark Matter in case
of Gaussian errors.


title:
Strangeness and Statistical Hadronization: How to Study Quark-Gluon
  Plasma

abstract:
  Statistical hadronization is presented as mechanism for (strange) particle
production from a deconfined quark--gluon plasma (QGP) fireball. We first
consider hadronic resonance production at RHIC as a test of the model.
  We present in detail how the hadrochemistry determines particle
multiplicities and in case of sudden hadronization allows investigation of QGP
properties. A comparative study of strange hadron production at SPS and RHIC is
presented. The energy dependence of physical observables shows regularities and
a potential discontinuity in the low RHIC range, when comparing these different
energy domains. Considering the energy scan program at CERN-SPS we show that
the K^+/\pi^+ discontinuity is a baryon density effect.


title:
Study of the Gauge Mediation Signal with Non-pointing Photons at the
  CERN LHC

abstract:
  In this paper we study the gauge mediation signal with the ATLAS detector at
the CERN LHC. We focus on the case where the NLSP is the long-lived lightest
neutralino ($\tilde{\chi}^0_1$) which decays dominantly into a photon
($\gamma$) and a gravitino ($\tilde{G}$). A non-pointing photon from the
neutralino decay can be detected with good position and time resolutions by the
electormagnetic calorimeter (ECAL), while the photon momentum would be
precisely measured if the photon is converted inside the inner tracking
detector before reaching the ECAL. A new technique is developed to determine
the masses of the slepton ($\tilde{\ell}$) and the neutralino from events with
a lepton and a converted non-pointing photon arising from the cascade decay
$\tilde{\ell}\to \ell\tilde{\chi}^0_1\to \ell\gamma \tilde{G}$. A Monte Carlo
simulation at a sample point shows that the masses would be measured with an
error of 3% for $\cal{O}$(100) selected $\ell\gamma$ pairs. Once the sparticle
masses are determined by this method, the decay time and momentum of the
neutralino are solved using the ECAL data and the lepton momentum only, for all
$\ell\gamma$ pairs without the photon conversion. We estimate the sensitivity
to the neutralino lifetime for $c\tau=10$ cm to $\cal{O}$(10) m.


title:
Neutralino-neutralino annihilation to photon and gluon pairs in MSSM
  models

abstract:
  The complete 1-loop computation of the processes $(\tchi^0_i \tchi^0_j
\leftrightarrow\gamma\gamma, ~ gg)$, for any pair of the four MSSM neutralinos,
has been performed for an arbitrary c.m energy. As a first application suitable
for Dark Matter (DM) searches, the neutralino-neutralino annihilation is
studied at relative velocities $v/c\simeq 10^{-3}$ describing the present DM
distribution in the galactic halo, and $v/c\simeq 0.5$ determining neutralino
relic density contributions. Numerical results are presented for 31 MSSM
benchmark models indicating considerable sensitivity to the input parameters.
Numerical codes are released, which may be used for the computation of the
annihilation of any two neutralinos to two photons or two gluons at the
aforementioned $v/c$ values. In the near future, we intend to complement them
with codes for the inverse process $\gamma\gamma \to \tchi^0_i \tchi^0_j$,

title: On Non-Gaussianity in the Curvaton Scenario

abstract:
  Since a positive future detection of non-linearity in the cosmic microwave
background anisotropy pattern might allow to descriminate among different
mechanisms giving rise to cosmological adiabatic perturbations, we study the
evolution of the second-order cosmological curvature perturbation on
super-horizon scales in the curvaton scenario. We provide the exact expression
for the non-Gaussianity in the primordial perturbations including gravitational
second-order corrections which are particularly relevant in the case in which
the curvaton dominates the energy density before it decays. As a byproduct, we
show that in the standard scenario where cosmological curvature perturbations
are induced by the inflaton field, the second-order curvature perturbation is
conserved even during the reheating stage after inflation.
