Modern Technique for Real Photon Radiative Correction Calculations

I. A. Shershan and T. V. Shishkina

The problem of the bremsstrahlung contribution calculation as a part of the radiative corrections in the case of single gauge boson production was discussed. It was shown that the hard photon bremsstrahlung contribution can be divided into the finite and divergent terms. The exact calculation of soft photon bremsstrahlung and infrared part of hard photon bremsstrahlung was presented in frame of the dimensional regularization scheme. Numerical analysis of radiative corrections to the cross sections of single gauge boson production was performed.

Key words: photon, electron, gauge boson, electroweak interaction, radiative corrections, linear colliders
