Description

Two-loop four-point QCD amplitudes receive elliptic contributions stemming from internal, massive quark loops. In this talk, I will explain how these contributions can be expressed in terms of iterated integrals over a set of independent kernels utilizing canonical differential equations. Further, I will demonstrate how the corresponding amplitudes can be evaluated numerically fast and reliable via appropriate series expansions.
