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…
