Title: Factorization of the connected prescription for Yang-Mills amplitudes

Abstract

We examine factorization in the connected prescription of Yang-Mills amplitudes. The multiparticle pole is interpreted as coming from representing delta functions as meromorphic functions. However, a naive evaluation does not give a correct result. We give a simple prescription for the integration contour which does give the correct result. We verify this prescription for a family of gauge-fixing conditions.
