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; ...
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 ...
Self-consistent solution of the Schwinger-Dyson equations for the nucleon and meson propagators
(1994-01-01)
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 ...
A dynamical gluon mass solution in Mandelstam's approximation
(World Scientific Publ Co Pte Ltd, 2005-12-30)
We discuss the pure gauge Schwinger-Dyson equation for the gluon propagator in the Landau gauge within an approximation proposed by Mandelstam many years ago. We show that a dynamical gluon mass arises as a solution. This ...
Phenomenology of infrared finite gluon propagator and coupling constant
(Sociedade Brasileira de Física, 2007-03-01)
We report on some recent solutions of the Dyson-Schwinger equations for the infrared behavior of the gluon propagator and coupling constant, discussing their differences and proposing that these different behaviors can be ...
Technicolor models with coupled systems of Schwinger-Dyson equations
(2019-03-01)
When technicolor (TC), QCD, extended technicolor (ETC), and other interactions become coupled through their different Schwinger-Dyson equations, the solutions of these equations are modified compared to those of the isolated ...
Fourth-order full quantum correlations from a Langevin-Schwinger-Dyson equation
(IOP Publishing, 2009-06)
It is well known that some quantum and statistical fluctuations of a quantum field may be recovered by adding suitable stochastic sources to the mean field equations derived from the Schwinger-Keldysh (closed-time path) ...
Freezing of the QCD coupling constant and solutions of Schwinger-Dyson equations
(American Physical Soc, 2002-03-01)
We compare phenomenological values of the frozen QCD running coupling constant (alpha(s)) with two classes of infrared finite solutions obtained through nonperturbative Schwinger-Dyson equations. We use these same solutions ...
Freezing of the QCD coupling constant and solutions of Schwinger-Dyson equations
(2002-01-01)
We compare phenomenological values of the frozen QCD running coupling constant (as) with two classes of infrared finite solutions obtained through nonperturbative Schwinger-Dyson equations. We use these same solutions with ...
Phenomenological tests for the freezing of the QCD running coupling constant
(2004-01-20)
We discuss phenomenological tests for the frozen infrared behavior of the running coupling constant and gluon propagators found in some solutions of Schwinger-Dyson equations of the gluonic sector of QCD. We verify that ...
