摘要：

I give a proof, using the unitarity-based method, of the collinear factorization of the leading-color contribution to gauge-theory amplitudes. The proof also provides a concrete formula which can be used to compute the associated splitting amplitudes. (C) 1999 Elsevier Science B.V. All rights reserved.
