Schwinger-dyson equations and dynamical gluon mass generation
(2005-04-14)
We discuss the solutions obtained for the gluon propagador in Landau gauge within two distinct approximations for the Schwinger-Dyson equations (SDE). The first, named Mandelstam's approximation, consist in neglecting all ...

Collective Perspective on Advances in Dyson-Schwinger Equation QCD
(Iop Publishing Ltd, 2012-07-01)
We survey contemporary studies of hadrons and strongly interacting quarks using QCD's Dyson-Schwinger equations,addressing the following aspects: confinement and dynamical chiral symmetry breaking; the hadron spectrum; ...
Symmetry-preserving contact interaction model for heavy-light mesons
(Amer Inst Physics, 2016-01-01)
We use a symmetry-preserving regularization method of ultraviolet divergences in a vector-vector contact interaction model for low-energy QCD. The contact interaction is a representation of nonperturbative kernels used ...
SELF-CONSISTENT SOLUTION OF THE SCHWINGER-DYSON EQUATIONS FOR THE NUCLEON AND MESON PROPAGATORS
(American Physical Soc, 1994-03-01)
The Schwinger-Dyson equations for the nucleon and meson propagators are solved self-consistently in an approximation that goes beyond the Hartree-Fock approximation. The traditional approach consists in solving the nucleon ...

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 ...
