Radiative corrections to DVCS electron tensor
Abstract
Radiative corrections in leading logarithmic approximation are calculated for the differential cross section of e- μ + radiative scattering. In particular the interference term due to photon emission from electron and muon blocks are calculated in helicity independent and dependent parts. The calculation is applied to the kinematical conditions of existing DVCS data in electron-proton collisions. Both helicity odd and helicity even differential cross sections are considered.
