A numerical evaluation of planar two-loop helicity amplitudes for a W-boson plus four partons
Abstract We present the first numerical results for the two-loop helicity amplitudes for the scattering of four partons and a W-boson in QCD. We use a finite field sampling method to reduce directly from Feynman diagrams to the coefficients of a set of master integrals after applying integration-by-...
