Application of Asymptotic Methods to Calculating Electroweak Corrections in Polarized Bhabha Scattering

Asymptotic expressions for one-loop electroweak radiative corrections to observables of polarized Bhabha scattering are obtained within the on-shell renormalization scheme. The results of a numerical analysis of relative one-loop electroweak corrections to the cross section and polarization asymmetry are reproduced at energies below and above the resonance. A successful comparison with exact results obtained by means of computer-algebra systems is performed.
