Automatic computation of Feynman integrals containing linear propagators via auxiliary mass flow
Zhi-Feng Liu, Yan-Qing Ma
Abstract
Evaluating Feynman integrals at higher orders in coupling constants in quantum field theories remains a complicated task. In this paper, the authors complete another step in the ongoing program of calculating Feynman integrals using the auxiliary mass flow method, namely they show how to include linear propagators up to four loops.
