Dressed perturbation theory for the quark propagator: Fernando Enrique Serna Algarín. -
(Universidade Estadual Paulista (Unesp), 2013-06-11)
The rainbow-ladder approximation is a simple nonperturbative truncation scheme for nonperturbative calculations in Quantum Chromodynamics (QCD). It provides satisfactory results for the ground-states of light pseudoscalar ...

Charge-symmetry breaking, rho-omega mixing, and the quark propagator
(Elsevier B.V., 1993-12-01)
The momentum dependence of the ρ0-ω mixing contribution to charge-symmetry breaking (CSB) in the nucleon-nucleon interaction is compared in a variety of models. We focus in particular on the role that the structure of the ...
Initial conditions dependency in heavy-quarks suppression in ultra-relativistic collisions.
(AIP Publishing LLCNew York, 2013-05-06)
Heavy quark suppression in central Au+Au collisions is expected to be smaller than that of light quarks. However experimental data suggest that they are evenly suppressed. We propose considering fluctuations in the medium ...
Quark Propagator in Minkowski Space
(Springer, 2019-09-01)
The analytic structure of the quark propagator in Minkowski space is more complex than in Euclidean space due to the possible existence of poles and branch cuts at timelike momenta. These singularities impose enormous ...
