For the large-angle hard-photon emission by initial leptons in the process of high-energy annihilation of e+ e- to hadrons, the Dirac tensor is obtained by taking the lowest-order radiative corrections into account. The case of large-angle emission of two hard photons by initial leptons is considered. In the final result, the kinematic case of collinear hard-photons emission and soft virtual and real photons is included; it can be used for the construction of Monte-Carlo generators.
