Radiative Effects in Processes of Electron-Positron Annihilation into Lepton Pairs
U. U. Khasianevich and T. V. Shishkina

Lowest-order radiative corrections to the process of electron-positron annihilation with lepton pairs production have been calculated in the frame of the Standard Model of electroweak interactions. The formulae are obtained in the Lorentz-invariant form without any additional approximation. Due to the longitudinally polarized initial particles consideration, not only differential and total cross section but polarized asymmetries were investigated as well.

Key words: differential cross section, total cross section, polarization asymmetry, renormalization, regularization, hard radiation, soft radiation, radiative corrections, virtual contribution, real contribution
