Simetria quiral, modelos de quarks e espalhamento píon-píon no formalismo fock-tani
(Universidade Estadual Paulista (UNESP), 1995)
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 ...
Simetria quiral: fótons, píons e núcleons
(Universidade Estadual Paulista (UNESP), 1994)
In this Work we study the role played by chiral and electromagnetic gauge symmetries, the weak constant 'g IND. A' and pion-nucleon couplings in three processes; single and double pion photo production and photon-nucleon ...
Dinâmica das transições quiral e de desconfinamento da cromodinâmica quântica com o modelo Polyakov-Nambu-Jona-Lasinio
(Universidade Estadual Paulista (UNESP), 2014-03-27)
Thermodynamic equilibrium and non-equilibrium properties of the light u and d quarks sector of Quantum Chromodynamics (QCD) are studied with the Polyakov–Nambu–Jona-Lasinio (PNJL) model. The PNJL model allows to take into ...
