Abstract

The electromagnetic radiative corrections toe+e − -annihilation into lepton pairs are calculated including hard photon bremsstrahlung in the standard and extended electroweak models. For\(\sqrt s \) = 38 GeV we find for the standard model, that the radiative corrections toZ-exchange reduce the charge asymmetry up to 1% which is mainly caused by the virtual and soft photon parts of the corrections. For models with a higher forward-backward asymmetry the situation is found to be quite similar.
