Effects of electroweak radiative corrections in polarized low-energy electron-positron annihilation into lepton pairs
Complete one-loop electroweak radiative corrections to the cross section of the process $e^+e^- \to μ^-μ^+ (τ^-τ^+)$ are evaluated with the help of the \SANC 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 $\sqrt{s}=5, ~7$~GeV for various polarization degrees of the initial particles.
