Query: Implications on SUSY breaking mediation mechanisms from observing $B_s
  \to \mu^+ \mu^-$ and the muon $(g-2)$   We consider $B_s \to \mu^+ \mu^-$ and the muon $(g-2)_\mu$ in various SUSY
breaking mediation mechanisms. If the decay $B_s \to \mu^+ \mu^-$ 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 $(g-2)_\mu$. On the other hand, the minimal
supergravity scenario and similar mechanisms derived from string models can
accommodate this observation.
