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…
One-loop N-point equivalence among negative-dimensional, Mellin-Barnes and Feynman parametrization approaches to Feynman integrals
A. T. Suzuki, E. S. Santos, A. G. M. Schmidt
We show that at one-loop order, negative-dimensional, Mellin-Barnes' (MB) and Feynman parametrization (FP) approaches to Feynman loop integrals calculations are equivalent. Startin…
General massive one-loop off-shell three-point functions
A. T. Suzuki, E. S. Santos, A. G. M. Schmidt
In this work we compute the most general massive one-loop off-shell three-point vertex in D-dimensions, where the masses, external momenta, and exponents of propagators are arbitra…
Massless and massive one-loop three-point functions in negative dimensional approach
A. T. Suzuki, E. S. Santos, A. G. M. Schmidt
In this article we present the complete massless and massive one-loop triangle diagram results using the negative dimensional integration method (NDIM). We consider the following c…
Negative dimensional approach for scalar two-loop three-point and three-loop two-point integrals
A. T. Suzuki, A. G. M. Schmidt
The well-known -dimensional Feynman integrals were shown, by Halliday and Ricotta, to be capable of undergoing analytic continuation into the domain of negative values for the d…
The light-cone gauge without prescriptions
A. T. Suzuki, A. G. M. Schmidt
Feynman integrals in the physical light-cone gauge are harder to solve than their covariant counterparts. The difficulty is associated with the presence of unphysical singularities…
