Calculating four-loop tadpoles with one non-zero mass
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)
terms in
D=4−2ϵ
space-time dimensions.
