One-loop Feynman integrals for 2 → 3 scattering involving many scales including internal masses
Abstract We study several multiscale one-loop five-point families of Feynman integrals. More specifically, we employ the Simplified Differential Equations approach to obtain results in terms of Goncharov polylogarithms of up to transcendental weight four for families with two and three massive exter...
