Title: Reduction of one-loop amplitudes at the integrand level - NLO QCD calculations
Authors: Ossola, Giovanni
Papadopoulos, Costas G.
Pittau, Roberto
Issue Date: 2008
Abstract: The recently proposed method (OPP) to extract the coefficients of the scalar one-loop integrals to any multi-particle (sub)-amplitude is described. Within this method no analytical information on the structure of the amplitude is needed, allowing for a purely numerical, but still algebraic, implementation of the algorithm. The algorithm can be used to automatically perform one-loop calculation both in QCD and in the EW Theory. As an application, we give QCD one-loop results for the process pp → ZZZ at the LHC.
