The Schwinger model on the null-plane
(2007-10-01)
We study the Schwinger Model on the null-plane using the Dirac method for constrained systems. The fermion field is analyzed using the natural null-plane projections coming from the γ-algebra and it is shown that the ...

Gamow states as solutions of a modified Lippmann-Schwinger equation
(World Scientific, 2016-07)
In this paper, we discuss the structure of Gamow states as solutions of Lippmann-Schwinger equation. The Friedrichs model is used to demonstrate it, both analytically and by applying perturbation theory to the extended ...
BRST-BFV formalism for the generalized Schwinger model
(Springer, 1997-07-01)
We derive the Wess-Zumino scalar term of the generalized Schwinger model both in the singular and nonsingular cases by using BRST-BFV framework. The photon propagators are also computed in the extended Lorentz gauge.

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 ...
