Infrared behavior of one-loop QCD amplitudes at next-to-next-to-leading order

We present universal factorization formulas describing the behavior of one-loop QCD amplitudes as external momenta become either soft or collinear. Our results are valid to all orders in the dimensional regularization parameter, epsilon. Terms through O(epsilon(2)) can contribute in infrared divergent phase space integrals associated with next-to-next-to-leading order jet cross sections. [S0556-2821(99)07417-2].
