摘要：

Top squark contributions to the radiative correction to Rb and the top quark decay are analyzed over the relevant MSSM parameter space. One sees a 30% increase in the former along with a similar drop in the latter in going from the Higgsino-dominated to the mixed region. Consequently, one can get a viable SUSY contribution to Rh within the constraint of the top quark data only in the mixed region, corresponding to a photino-dominated LSP. We discuss the phenomenological implications of this model for top quark decay and direct top squark production, which can be tested with the Fermilab Tevatron data.
