Optimized δ expansion for the Walecka model
(Elsevier B.V., 1996-03-07)
The optimized δ-expansion is used to study vacuum polarization effects in the Walecka model. The optimized δ-expansion is a nonperturbative approach for field theoretic models which combines the techniques of perturbation ...
Chiral symmetry breaking in QCD-like gauge theories with a confining propagator and dynamical gauge boson mass generation
(Academic Press Inc. Elsevier B.V., 2012-04-01)
We study chiral symmetry breaking in QCD-like gauge theories introducing a confining effective propagator, as proposed recently by Cornwall, and considering the effect of dynamical gauge boson mass generation. The effective ...
QCD effective charge and the structure function F-2 at small-x
(Elsevier B.V., 2011-03-28)
We study infrared contributions to the QCD description of the HERA data on the structure function F-2 within the generalized DAS approximation. We argue that this approximation is a natural one and consistent with the ...
Quantum gravity and the holographic dark energy cosmology
(2016-04-01)
The holographic dark energy model is obtained from a cosmological constant generated by generic quantum gravity effects giving a minimum length. By contrast, the usual bound for the energy density to be limited by the ...

A dynamical gluon mass solution in a coupled system of the Schwinger-Dyson equations
(2004-08-01)
We study numerically the Schwinger-Dyson equations for the coupled system of gluon and ghost propagators in the Landau gauge and in the case of pure gauge QCD. We show that a dynamical mass for the gluon propagator arises ...
