Calculating gluon one-loop amplitudes numerically

Abstract

This note reports on an independent implementation of calculating one-loop amplitudes semi-numerically using generalized unitarity techniques. The algorithm implemented in form of a C++ code closely follows the method by Ellis, Giele, Kunszt and Melnikov. For the case of gluons, the algorithm is briefly reviewed. Double-precision results are presented documenting the accuracy and efficiency of this computation.
