Description

We analyse virtual effects due to the minimal supersymmetric two-Higgs doublets model on top of the Z resonance. We find that the precise measurement of the Z partial decay width into b quarks and the forward-backward asymmetry for b jets which will be performed at LEP, may allow for indirect signals of supersymmetric nature. If no deviation from the standard model predictions is felt by the two observables, one can improve the existing limits on the additional parameters of the model. (orig.)
