Equações de Schwinger-Dyson e quebra dinâmica de simetrias
(Universidade Estadual Paulista (Unesp), 2000)
Unitarity of the time-evolution and observability of non-Hermitian Hamiltonians for time-dependent Dyson maps
(Iop Publishing Ltd, 2020-06-01)
We present an strategy for the derivation of a time-dependent Dyson map which ensures simultaneously the unitarity of the time evolution and the observability of the whole time-dependent non-Hermitian Hamiltonian or parts ...
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 ...
