The high energy logarithms in two loop electroweak Bhabha scattering

• Bhabha Scattering is the scattering of an electron off of a positron; it is everywhere in particle physics and plays a special role in particle phenomenology. Its particular use as a luminosity measure in particle colliders gives great motivation to reduce the theoretical uncertainty in the cross section. We calculate the two loop contribution to Bhabha scattering from high energy Sudakov logarithms. This contribution reduces the overall uncertainty in the cross section to one per mille, the necessary level for use
  at the ILC.
