A new method for the numerical evaluation of one-loop amplitudes
arXiv:0709.2332
Abstract
We recently presented a new method for the evaluation of one-loop amplitude of arbitrary scattering processes, in which the reduction to scalar integrals is performed at the integrand level. In this talk, we review the main features of the method and briefly summarize the results of the first calculations performed using it.
