Automatizing the application of Mellin-Barnes representations for Feynman integrals

Abstract

Feynman diagrams may be evaluated by Mellin-Barnes representations of their Feynman parameter integrals in d=4-2 dimensions. Recently, the Mathematica toolkit AMBRE has been developed for the automatic derivation of such representations with a loop-by-loop approach. We describe the package and exemplify its use with the -expansion of the massive one-loop QED vertex function.
