Unitary approximation for radiative high energy scattering processes: Application to Bhabha scattering

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

We describe how to apply the unitary approximation to high energy scattering processes which involve the radiation of arbitrarily many photons. We compare our results to calculations of inclusive quantities using leading log resummation techniques well known from QCD. In contrast to the latter method the unitary approximation is also appropriate for differential cross sections. The Monte Carlo implementation of the method is discussed and detailed results are given for the case of radiative Bhabha scattering.
