One-loop electroweak radiative corrections to lepton pair production in polarized electron-positron collisions

This paper presents high-precision theoretical predictions for s-channel ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{l}^{\ensuremath{-}}{l}^{+}$ scattering. The calculations are performed using the sanc system. They take into account complete one-loop electroweak radiative corrections as well as the longitudinal polarization of the initial beams. The reaction observables are obtained using the helicity amplitude method with taking into account the initial- and final-state fermion masses. Numerical results are given for the center-of-mass energy range $\sqrt{s}=250--1000\text{ }\text{ }\mathrm{GeV}$ with various degrees of polarization.
