摘要：

An efficient numerical algorithm to evaluate one-loop amplitudes is presented. It expresses the amplitude in terms of universal tensor integrals and their process-dependent coefficients, both of which are calculated with recursive methods. It is shown by explicit calculations that for ordered QCD amplitudes with a number of external legs up to 10, its performance is competitive with other methods.
