$R_b$ in the MSSM: how big can it be?
The possible magnitude of the supersymmetric contribution to Rb with imposed all available phenomenological constraints and demanding good quality of the global fit to the precision electroweak data is summarized. For small tan$\beta$ and $M_{2} \approx |\mu| and \mu < 0$, Rb remains large, ~ 0.2...
