Abstract

We study constraints on the Minimal Supersymmetric Standard Model from electroweak experiments. We find that the light sfermions always make the fit worse than the Standard Model, while the light chargino generally make the fit slightly better through the oblique corrections. The best overall fit to the precision measurements are found when the mass of lighter chargino is about 100 GeV and the SU(2)_L doublet sfermions are all much heavier. We find the slight improvement of the fit over the SM, where the total \chi^2 of the fit decreases by about one unit.
