Two-loop QED corrections to Bhabha scattering

arXiv:0704.3582 · doi:10.1088/1126-6708/2007/06/084

Abstract

We obtain a simple relation between massless and massive scattering amplitudes in gauge theories in the limit where all kinematic invariants are large compared to particle masses. We use this relation to derive the two-loop QED corrections to large-angle Bhabha scattering.
