For the large-angles hard photon emission by initial leptons in process ofhigh energy annihilation of $e^+ e^- \to $ to hadrons the Dirac tensor isobtained, taking into account the lowest order radiative corrections. The caseof large-angles emission of two hard photons by initial leptons is considered.This result is being completed by the kinematics case of collinear hard photonsemission as well as soft virtual and real photons and can be used forconstruction of Monte-Carlo generators.
