TTP08-13 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 $p_T$ above 1TeV the electroweak corrections may well reach several tens of percent. A similar situation is observed for top-antitop quark producition at large invariant mass of the $t\bar{t}$ system.
