Automated computation of one-loop integrals in massless theories
Andre van Hameren, Jens Vollinga, Stefan Weinzierl
Abstract
We consider one-loop tensor and scalar integrals, which occur in a massless quantum field theory and we report on the implementation into a numerical program of an algorithm for the automated computation of these one-loop integrals. The number of external legs of the loop integrals is not restricted. All calculations are done within dimensional regularization.
