Description:
Author(s): S. Abreu, F. Febres Cordero, H. Ita, M. Jaquier, and B. Page We describe the unitarity approach for the numerical computation of two-loop integral coefficients of scattering amplitudes. It is well known that the leading propagator singularities of an amplitude’s integrand are related to products of tree amplitudes. At two loops, Feynman diagrams with doubled … [Phys. Rev.
