Four-particle scattering amplitudes in QCD at NNLO to higher orders in the dimensional regulator
Abstract We compute all helicity amplitudes for four particle scattering in massless QCD with n f fermion flavours to next-to-next-to-leading order (NNLO) in perturbation theory. In particular, we consider all possible configurations of external quarks and gluons. We evaluate the amplitudes in terms...
