We first discuss the non-relativistic Bethe-Salpeter equation and its
general solution for the boson fields.
Then we continue with the relativistic case of the equation and its solution
in the ladder approximation.
Finally we discuss a formulation of a possible analogue of the B-S equation
for
unstable states.

We review the different approaches for the study of spin 3/2 fields. By using a super Higgs
mechanism we get mass for the spin 3/2 field and analyze the algebra of constraints in the formalism beyond the Rarita-Schwinger formalism (NKR).

On september 30th, the Tevatron collider at Fermilab was turned off
for good, and with it
came to end the data taking of the DZero experiment. During a decade,
DZero collected
data that allowed the collaboration to perform hundreds of analysis,
but in particular,
to contribute to the better understanding of B hadrons and its
properties. In a decade of
data taking, B hadron proppert

A systematic low-energy effective field theory for hole-doped
antiferromagnets on the honeycomb lattice is constructed. The formalism
is then used to investigate spiral phases in the staggered magnetization
as well as the formation of two-hole bound states.

Baryon properties are computed at one-loop order in heavy baryon chiral perturbation theory in the large-N limit, where N is the number of colors. Loop graphs with octet and decuplet intermediate states cancel to various orders in N as a consequence of the large-N spin-flavor symmetry of QCD baryons. These cancellations are explicitly shown for the general case of N_f flavors of light quarks. In p

We study relevance of conformal symmetry breaking through
the dilaton mass on the high-lying spectra of the unflavored mesons.
The conformal symmetry is supposed to leave a footprint in those spectra
in consequence of the gauge-gravity duality conjecture in combination with
the opening of a conformal window in the infrared as recently observed
experimentally through the property of the r

I will present a numerical solution of the coupled Dyson-Schwinger equations for the ghost and gluon propagators in Yang-Mills theory in Landau gauge. Aimed at investigating the infrared behaviour of the propagators, the equations are simplified by truncating the gluon loops, according to the ghost dominance hypothesis motivated by the Gribov-Zwanziger scenario.
I have solved the equations with

We calculate the static electromagnetic moments of an elementary particle with spin, in particular the spin 3/2 case, and relate the result to Compton scattering in the forward direction. We start from a second order Lagrangian based on the properties of a particle viewed as a state transforming under some representation of the Poincaré group. Coupled to an electromagnetic field, this Lagrangian

The properties of the nuclear modification factor for heavy flavors
are usually attributed to the energy loss suffered by the heavy quark
propagating in a QCD plasma. Nevertheless it is a bit surprising that
the suppression of this factor is as strong as the one suffered by
light flavors. In this work we show that when accounting for the
momentum shift associated to the opening of the recombi

The QCD interaction is flavour-blind. Neglecting electromagnetic and weak interactions, the only difference between flavours is caused by the different quark masses. We explain how flavour-blindness constrains hadron masses and matrix elements after flavour SU(3) is broken by the mass difference between the strange and light quarks. We use this knowledge to help us extrapolate 2+1 flavour lattice

We study the one loop renormalization of the electromagnetic interactions
of a second order formalism for spin 1/2 fermions arising from projectors onto
invariant subspaces of the Poincaré group. Using dimensional regularization and
the mass-shell substraction scheme it is shown that the vacuum polarization,
fermion self energy and vertex interactions associated with the interacting

The LHCb is an experiment dedicated to $b$ and $c$ physics at the
LHC. In 2011 a total integrated luminosity of 600 pb-1 has been
already collected at a centre of mass energy of 7 TeV.
A concise review of the detector design and performance will be
presented, together with a selection of preliminary physics
results obtained with 300 pb-1 of 2011's data and the prospects for
some of the me

In 2010, the LHC started taking data from p-p collisions with a center-of-mass energy of 7 TeV and the ATLAS Experiment obtained its first W' and Z' exclusion limits with 42 pb-1 of integrated luminosity. In 2011, the LHC continues taking data at 7 TeV and the ATLAS Experiment recorded up to 1.21fb-1 of integrated luminosity this summer. This presentation will show the lepton+MET and dilepton sign

The production of high transverse momentum events containing charged leptons
and jets has been measured, using 1 fb-1 of data recorded by the ATLAS
detector in 2011 at sqrts = 7 TeV. No excess beyond Standard Model
expectations is observed, and lower limits on effective cross sections are
set. Using models for string ball and black hole production and decay,
exclusion contours are determined

The spin and flavor content of baryons is studied in the framework of the unquenched quark model in which the effects of quark-antiquark pairs (flavor u, d and s) are taken into account via a microscopic, QCD-inspired, quark-antiquark creation mechanism. The inclusion of the quark-antiquark pairs leads to a relatively large contribution or orbital angular momentum to the proton spin [1] which may

The infrared behavior of gluon and ghost propagators in Landau gauge Yang-Mills theory has been at the center of an intense debate over the last decade. Different solutions of the Dyson-Schwinger equations show a power law ("scaling solutions") or a massive behavior (for the gluons, "decoupling solutions") of the propagators in the infrared. The latest lattice results favor the decoupling solution

We determine the value of the $\omega -\rho- \pi$ mesons coupling ($g_{\omega\rho\pi} $), in the context of the vector meson dominance model, from radiative decays, the $\omega \rightarrow 3\pi$ decay width and the $e^+e^- \rightarrow 3\pi$ cross section.
For the last two observables we consider the presence of a contact term as mimicked by a heavier resonance ($\rho'(1450)$) and find its magni

In gauge theories the field configurations often occur in
distinct topological sectors. In a lattice regularized
system with chiral fermions, these sectors can be defined
by adapting the Atiyah-Singer Index Theorem. If such a model is
simulated with local updates of the lattice gauge configuration,
the Monte Carlo history tends to get stuck in one sector for many
step, in particular on fine

The dynamics of the time evolution of an order parameter towards equilibrium is a much-studied problem in nonequilibrium statistical mechanics. Typically, when a system consisting of a two-phase mixture in a homogeneous phase is rapidly driven across the critical coexistence temperature into a nonequilibrium state, fluctuations around the initial homogeneous state will develop; the system will bre
