Abstract

We describe the impact of the full one-loop EW terms of O(alpha_s alpha_EM³) entering the electron-positron into three-jet cross-section from √(s)=M_Z to TeV scale energies. We include both factorisable and non-factorisable virtual corrections, photon bremsstrahlung but not the real emission of W and Z bosons. Their importance for the measurement of alpha_S from jet rates and shape variables is explained qualitatively and illustrated quantitatively.
