Hard scattering and electroweak corrections at high energies

After a brief recollection of joint scientific work with Staszek Jadach, recent results on electroweak radiative corrections for scattering processes in the TeV region are presented. The status of the four-fermion scattering amplitudes is discussed, with emphasis on logarithmically enhanced contributions in two-loop approximation. Predictions for the production of gamma, Z and W with large transverse momenta together with a jet are presented. For PT above I TeV the electroweak corrections may well reach several tens of percent. A similar situation is observed for top-antitop quark production at large invariant mass of the tt system.
