Constructing QCD Loop Amplitudes Using Collinear Limits
G. Chalmers
Abstract
We discuss how higher-point QCD amplitudes may be constructed from lower point ones by imposing the factorization constraints in the limits as external momenta become collinear. As a particular example, the all-n gluon one-loop amplitude with maximal helicity violation is presented. We also discuss the necessary collinear behavior of the n-gluon amplitudes.
