IR finite one-loop box scalar integral with massless internal lines

arXiv:hep-ph/0201306 · doi:10.1007/s100520200943

Abstract

The IR finite one-loop box scalar integral with massless internal lines has been recalculated. The result is very compact, simple and valid for arbitrary values of the relevant kinematic variables. It is given in terms of only two dilogarithms and a few logarithms, all of very simple arguments.
