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…
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…
Feynman integrals with tensorial structure in the negative dimensional integration scheme
A. T. Suzuki, A. G. M. Schmidt
Negative dimensional integration method (NDIM) is revealing itself as a very useful technique for computing Feynman integrals, massless and/or massive, covariant and non-covariant…
Probing negative dimensional integration: two-loop covariant vertex and one-loop light-cone integrals
A. T. Suzuki, A. G. M. Schmidt, R. Bentín
Negative dimensional integration method (NDIM) seems to be a very promising technique for evaluating massless and/or massive Feynman diagrams. It is unique in the sense that the me…
