Evaluating multiloop Feynman integrals by Mellin-Barnes representation
arXiv:hep-ph/0406052 · doi:10.1016/j.nuclphysbps.2004.09.024
Abstract
The status of analytical evaluation of double and triple box diagrams is characterized. The method of Mellin-Barnes representation as a tool to evaluate master integrals in these problems is advocated. New MB representations for massive on-shell double boxes with general powers of propagators are presented.
