Approximate Universality of N=4 Super-Yang--Mills One-Loop Amplitudes
David C. Dunbar, James H. Ettle, Warren B. Perkins
A study of the colour-ordered one-loop amplitudes in N=4 SYM reveals a surprising property: numerically, the amplitudes have an Approximately Universal form A^{1-loop}_n ~ A^{tree}…

The Unitarity Method using a Canonical Basis Approach
David C. Dunbar, Warren B. Perkins, Edmund Warrick
Various implementations of the Unitarity method have been developed to compute one-loop amplitudes in gauge theories. In this paper we present an implementation which uses canonica…
