Theoretical improvements for luminosity monitoring at low energies
arXiv:1201.0968
Abstract
A comparison of theoretical results on NNLO leptonic and hadronic corrections to Bhabha scattering with the Monte Carlo generator BabaYaga@NLO used at meson factories is given. Complete NLO virtual corrections to the $e^+e^- \to μ^+ μ^- γ$ process are discussed.
