Infrared and transcendental structure of two-loop supersymmetric QCD amplitudes
Abstract Using a careful choice of infrared (IR) subtraction scheme, we demonstrate cancellation of all terms with transcendental weights 0, 1, 2 from the finite part of the full-color two-loop four-gluon N $$ \mathcal{N} $$ = 2 supersymmetric QCD amplitude, with N f massless supersymmetric quarks....
