General Subtraction Method for Numerical Calculation of One-Loop QCD Matrix Elements

Z. Nagy, D.E. Soper

We present a subtraction scheme for eliminating the ultraviolet, soft, and collinear divergences in the numerical calculation of an arbitrary one-loop QCD amplitude with an arbitrary number of external legs. The subtractions consist of local counter terms in the space of the four-dimensional loop momentum.
