Analytic results for planar three-loop integrals for massive form factors

High Energy Physics - Phenomenology 2017-02-01 v1

Abstract

We use the method of differential equations to analytically evaluate all planar three-loop Feynman integrals relevant for form factor calculations involving massive particles. Our results for ninety master integrals at general q2q^2 are expressed in terms of multiple polylogarithms, and results for fiftyone master integrals at the threshold q2=4m2q^2=4m^2 are expressed in terms of multiple polylogarithms of argument one, with indices equal to zero or to a sixth root of unity.
