Analyzing dynamical gluon mass generation
(Sociedade Brasileira Fisica, 2007-03-01)
We study the necessary conditions for obtaining infrared finite solutions from the Schwinger-Dyson equation governing the dynamics of the gluon propagator. The equation in question is set up in the Feynman gauge of the ...
Chiral symmetry, massive gluons and confinement
(2013-04-24)
It is quite difficult to obtain non-trivial chiral symmetry breaking solutions for the quark gap equation in the presence of dynamically generated gluon masses. An effective confining propagator has recently been proposed ...
A heuristic approach for accessing and employing the infrared behavior of Yang-Mills correlation functions
(2013-04-24)
This work analyses a hypothetically improved perturbative approach taking a dressed massive-like gluon propagator and an effective coupling into account. As an early step, corrections were calculated to the ghost and gluon ...
Effects of dynamical masses of gluons and quarks on hadronic B decays
(2010-12-01)
We study hadronic annihilation decays of B mesons within the perturbative QCD at collinear approximation. The regulation of endpoint divergences is performed with the help of an infrared finite gluon propagator characterized ...
Effects of dynamical masses of gluons and quarks on hadronic B decays
(Amer Inst Physics, 2010-01-01)
We study hadronic annihilation decays of B mesons within the perturbative QCD at collinear approximation. The regulation of endpoint divergences is performed with the help of an infrared finite gluon propagator characterized ...
Chiral phases of fundamental and adjoint quarks
(2016-01-22)
We consider a QCD chiral symmetry breaking model where the gap equation contains an effective confining propagator and a dressed gluon propagator with a dynamically generated mass. This model is able to explain the ratios ...
Chiral symmetry breaking with a confining propagator and dynamically massive gluons
(2011-12-01)
Chiral symmetry breaking in QCD is studied introducing a confining effective propagator, as proposed recently by Cornwall, and considering the effect of dynamically massive gluons. The effective confining propagator has ...
Mass Generation And The Problem Of Seagull Divergences

Study of the (D)over-barN Interaction in a QCD Coulomb Gauge Quark Model
(E D P Sciences, 2009-01-01)
We study the (D) over barN interaction at low energies with a quark model inspired in the QCD Hamiltonian in Coulomb gauge. The model Hamiltonian incorporates a confining Coulomb potential extracted from a self-consistent ...
