Singularity-softening prescription for the Bethe-Salpeter equation
J. H. O. Sales, A. T. Suzuki
The reduction of the two fermion Bethe-Salpeter equation in the framework of light-front dynamics is studied for one gauge A+=0. The arising effective interaction can be perturbati…

Light-front time picture of the Bethe-Salpeter equation
Tobias Frederico, J. H. O. Sales, B. V. Carlson +1
We show the light-front representation of the field theoretical Bethe-Salpeter equation (BSE) in the ladder approximation using the quasi potential reduction. We discuss the equiva…
