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 few-body systems
T. Frederico, J. H. O. Sales, B. V. Carlson +1
The projection of the four-dimensional two-body Bethe-Salpeter equation at the light-front hypersurface is discussed. Elimination of the relative time is performed using a quasi-po…
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…
Light-Front Bethe-Salpeter Equation
J. H. O. Sales, T. Frederico, B. V. Carlson +1
A three-dimensional reduction of the two-particle Bethe-Salpeter equation is proposed. The proposed reduction is in the framework of light-front dynamics. It yields auxiliary quant…
Pairs in the light-front and covariance
J. P. B. C de Melo, J. H. O. Sales, T. Frederico +1
The electromagnetic current of bound systems in the light-front is constructed in the Breit-Frame, in the limit of momentum transfer vanishing. In this limit, the p…
