Two-Loop Photonic Corrections to Massive Bhabha Scattering

Abstract

We describe the details of the evaluation of the two-loop radiative photonic corrections to Bhabha scattering. The role of the corrections in the high-precision luminosity determination at present and future electron-positron colliders is discussed.
