摘要：

We examine one-loop vertex corrections to the process Z --> bbBAR in the minimal supersymmetric standard model. The amplitude for this process may be enhanced by large Yukawa couplings which arise in the case of a heavy top or a very large value of tan-beta. This leads to the possibility that supersymmetry might be observed indirectly by precision measurements of B(Z --> bbBAR).
