Abstract
The electron current tensor for the scattering of a heavy photon on a longi tudinally polarized electron accompanied with an additional electron-positr on pair is considered. The contribution of soft and hard collinear and quas i-collinear pairs is taken into account. The full analysis of the spin-inde pendent and spin-dependent parts of the electron current tensor is performe d. The results allow us to calculate the corresponding contribution into th e second-order radiative correction to cross sections for different process es with the next-to-leading accuracy.
