Emission of Two Hard Photons in Large-Angle Bhabha Scattering

Abstract

A closed expression for the differential cross section of the large-angle Bhabha $e^{+}{e}^{-}$ scattering which explicitly takes into account the leading and next-to-leading contributions due to the emission of two hard photons is presented. Both collinear and semi-collinear kinematical regions are considered. The results are illustrated by numerical calculations.
