Effects of electroweak radiative corrections in polarized low-energy electron-positron annihilation into lepton pairs
Abstract
Complete one-loop electroweak radiative corrections to the cross section of the process e+e- μ-μ+ (τ-τ+) are evaluated with the help of the system. Higher-order contributions of the initial state radiation are computed in the QED structure function formalism. Numerical results are given for the center-of-mass energy range s=5, ~7~GeV for various polarization degrees of the initial particles.
