Conclusion We reported current limits on flavor mixing in b-s
transitions in minimal supersymmetry (beyond leading order+Higgs mediated).
Constraint from Bs mixing is quite severe for RR and RL mixing at moderate-large tanβ (~30) despite relatively large theoretical uncertainty.
Precision measurement of Φ3 + Bs mixing can improve the bound (or find NP) as well as BR(Bs→μμ).
Low tanβ region can be covered by tCPV in radiative decay.
Combined with the spectrum measurement, such a measurement provides a clue to high energy scale.
