Abstract

We present the complete one-loop corrections to the sfermion pair production process e+e- -> sf_i sf_j (f = t, b, tau, nu_tau, u, d, s, c) in the Minimal Supersymmetric Standard Model. Our results also include the previously calculated SUSY-QCD corrections. We present some 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) ~ 1 Tev). At these energies an important part of the weak corrections stems from the box contribution. We also include cross-sections for polarized beams and left-right asymmetry.
