Electron-positron annihilation into heavy leptons at two loops

Year: 2025

Type: article

Abstract: A bstract We calculate the NNLO QED corrections to the C -even part of differential cross section of e + e − → μ + μ − process. We neglect power corrections in the electron mass and obtain the result in terms of Goncharov’s polylogarithms.
