Seminumerical evaluation of one-loop corrections

We present a seminumerical algorithm to calculate one-loop virtual corrections to scattering amplitudes. The divergences of the loop amplitudes are regulated using dimensional regularization. We only treat in detail the case of amplitudes with up to five external legs and massless internal lines, al...
