| Abstract: |
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 canonical forms to generate the rational coefficients of the basis integral functions. As an example, we present the results for the N=1 contribution to seven gluon scattering in closed, rational, analytic form. |
