Complete one--loop corrections to e+e- -> sfᵢ sfⱼ

Original · EN

We have calculated the complete one-loop corrections to the sfermion pair production process e+e- -> sfᵢ sfⱼ (f = t, b, tau, tau-neutrino) in the Minimal Supersymmetric Standard Model. Our results also include the previously calculated SUSY-QCD corrections. We present the details of the renormalization scheme used. It is found that the weak corrections are of the same magnitude as the SUSY-QCD corrections at higher energies (sqrt(s) 1TeV). At these energies the main part of the weak corrections stems from the box contribution. This is best seen in sneutrino production.
