On the Factorisation of the Connected Prescription for Yang-Mills Amplitudes
arXiv:hep-th/0612250 · doi:10.1103/PhysRevD.75.025028
Abstract
We examine factorisation in the connected prescription of Yang-Mills amplitudes. The multi-particle 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.
