Calculating four-loop tadpoles with one non-zero mass

High Energy Physics - Phenomenology 2009-11-11 v2

Abstract

An efficient method to calculate tadpole diagrams is proposed. Its capability is demonstrated by analytically evaluating two four-loop tadpole diagrams of current interest in the literature, including their O(ϵ)O(\epsilon) terms in D=42ϵD=4-2\epsilon space-time dimensions.
