The $n_f^2$ contributions to fermionic four-loop form factors

High Energy Physics - Phenomenology 2017-07-19 v1

Abstract

We compute the four-loop contributions to the photon quark and Higgs quark form factors involving two closed fermion loops. We present analytical results for all non-planar master integrals of the two non-planar integral families which enter our calculation.
