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.
