Abstract
We compute the minimal supersymmetry model one-loop contributions to the asymptotic energy behavior of fermion-antifermion pair production at future lepton-antilepton colliders. In addition to the conventional logarithms of renormalization group origin, extra supersymmetry linear logarithmic terms appear of “Sudakov-type.” In the TeV range their overall effect on a variety of observables can be quite relevant and drastically different from that obtained in the standard model case.
