Two-Loop Correction to Bhabha Scattering
We present the two-loop virtual QED corrections to e{sup +}e{sup -} {yields} {mu}{sup +} {mu}{sup -} and Bhabha scattering in dimensional regularization. The results are expressed in terms of polylogarithms. The form of the infrared divergences agrees with previous expectations. These results are a crucial ingredient in the complete next-to-next-to-leading order QED corrections to these processes. A future application will be to reduce theoretical uncertainties associated with luminosity measurements at e{sup +}e{sup -} colliders. The calculation also tests methods that may be applied to analogous QCD processes.
