Conclusion

• We reported current limits on flavor mixing in
  b-s transitions in minimal supersymmetry (beyond
  leading orderHiggs mediated).
• Constraint from Bs mixing is quite severe for RR
  and RL mixing at moderate-large tanß(30)despite
  relatively large theoretical uncertainty.
• Precision measurement of F3 Bs mixing can
  improve the bound (or find NP) as well as
  BR(Bs?µµ).
• Low tanß region can be covered by tCPV in
  radiative decay.
• Combined with the spectrum measurement, such a
  measurement provides a clue to high energy scale.
