Mellin$-$Barnes Transformation for Two-Loop Master-Diagram

High Energy Physics - Theory 2023-10-05 v2

Abstract

In the paper, we obtain an expression for a two-loop master-diagram by using the Mellin-Barnes transformation. In the two-dimensional case we managed to factorize the answer and write it as a bilinear combination of hypergeometric functions 3F2{}_3F_2.
