Violation of the factorization theorem in large-angle radiative Bhabha scattering

The lowest order QED radiative corrections to the radiative large-angle Bhabha scattering process in the region where all the kinematical invariants are large compared to the electron mass are considered. We show that the leading logarithmic corrections do not factor before the Born cross section, contrary to the picture assumed in the renormalization group approach. Estimation of the leading and nonleading contributions for typical kinematics of the hard process for energy of Φ factory is done
