Electron-positron annihilation into heavy leptons at two loops
Year: 2025
Type: preprint
Abstract: We calculate the NNLO QED corrections to the $C$-even part of differential cross section of $e^+e^- \to μ^+μ^-$ process. We neglect power corrections in the electron mass and obtain the result in terms of Goncharov's polylogarithms.
