Description

We consider $B_s \to μ^+ μ^-$ and the muon $(g-2)_μ$ in various SUSY breaking mediation mechanisms. If the decay $B_s \to μ^+ μ^-$ is observed at Tevatron Run II with a branching ratio larger than $\sim 2 \times 10^{-8} $, the noscale supergravity (including the gaugino mediation), the gauge mediation scenario with small number of messenger fields and low messenger scale, and a class of anomaly mediation scenarios will be excluded, even if they can accommodate a large muon $(g-2)_μ$. On the other hand, the minimal supergravity scenario and similar mechanisms derived from string models can accommodate this observation.
