Abstract

We calculate the universal flavor-singlet radiative QED corrections to unpolarized lepton scattering applicable to general differential scattering cross sections, involving charged fermions or photons in initial or final states. The radiators are derived to $O ((α ln (Q^{2} / m_{f}^{2}))^{5})$ in analytic form. Numerical illustrations are given.
