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.}, organization = {Work supported by HEPTOOLS, MRTN-CT-2006-035505 and ALGOT OOLS, MTKD-CT-2004-014319.}, publisher = {Jagiellonian University}, keywords = {Jet cross-sections}, keywords = {General algorithm}, title = {Reduction of one-loop amplitudes at the integrand level - NLO QCD calculations}, author = {Ossola, Giovanni and Papadopoulos, Costas G. and Pittau, Roberto}, }
