Asymptotic expansions of Feynman diagrams and the Mellin-Barnes representation

Abstract

In this talk, we describe part of our recent work \cite{FGdeR05} (see also \cite{F05,G05}) that gives new results in the context of asymptotic expansions of Feynman diagrams using the Mellin-Barnes representation.Comment: Talk given at the $12^{th}$ High-Energy Physics International Conference on Quantum Chromodynamics, 4-8 July (2005), Montpellier (France
