Abstract

We report on the effect that one-loop radiative corrections to the chargino pair production cross section has on the determination of the fundamental parameters of the theory. We work in the context of electron-positron colliders with sqrt(s)=500 GeV. We conclude that the inclusion of these corrections is crucial in precision measurements, specially at large and small values of tan(beta).
