Description
We present some recent results on the evaluation of massive one-loop multileg Feynman integrals, which are of relevance for LHC processes.
An efficient complete analytical tensor reduction was derived and implemented in a Mathematica package hexagon.m.
Alternatively, one may use Mellin-Barnes techniques in order to avoid the tensor reduction.
We shortly report on a new version of the Matheamtica package AMBRE.m.
