AMFlow: a Mathematica package for Feynman integrals computation via Auxiliary Mass Flow

High Energy Physics - Phenomenology 2022-10-28 v3 High Energy Physics - Theory

Abstract

AMFlow is a Mathematica package to numerically compute dimensionally regularized Feynman integrals via the recently proposed auxiliary mass flow method. In this framework, integrals are treated as functions of an auxiliary mass parameter and their results can be obtained by constructing and solving differential systems with respect to this parameter, in an automatic way. The usage of this package is described in detail through an explicit example of double-box family involved in two-loop ttˉt\bar{t} hadroproduction.
