Beschreibung
Zusammenfassung:	A total set of one-loop electroweak radiative corrections, including the contribution of the emission of real hard photons (hard-bremsstrahlung contribution), to observables of polarized Bhabha scattering is calculated. A numerical analysis of observed spatial and polarization asymmetries with allowance for electroweak corrections is performed for low-energy experiments of the Belle II type and for the future electron– positron collider ILC/CLIC.
