Generalised Unitarity for Dimensionally Regulated Amplitudes

Published 21 May 2015 in hep-ph | (1505.05890v1)

Abstract: We present a novel set of Feynman rules and generalised unitarity cut-conditions for computing one-loop amplitudes via d-dimensional integrand reduction algorithm. Our algorithm is suited for analytic as well as numerical result, because all ingredients turn out to have a four-dimensional representation. We will apply this formalism to NLO QCD corrections.
