Three-loop helicity amplitudes for quark-gluon scattering in QCD
Abstract We compute the three-loop helicity amplitudes for q q ¯ $$ q\overline{q} $$ → gg and its crossed partonic channels, in massless QCD. Our analytical results provide a non-trivial check of the color quadrupole contribution to the infrared poles for external states in different color represent...
