  1. 特定領域「フレーバー物理の新展開」研究会２００９ @ 蒲郡 B physics and supersymmetry with general flavor mixing Ken-ichi Okumura (Tohoku University) In collaboration with John Foster and Leszek Roszkowski Based on hep-ph/0604121, hep-ph/0510422, hep-ph/0506146, hep-ph/0410323

  2. Plan of talk • Introduction • Supersymmetry with general flavor mixing • b-s transitions • Conclusion

  3. The SM: CKM paradigm

  4. Why Supersymmetry ? SM S.P.Martin (1997) MSSM

  5. Supersymmetry doubles flavor Soft mass Tri-linear term Gaugino mass

  6. Minimal flavor violation (MFV) Super CKM basis

  7. General Flavor Mixing

  8. Origin of flavor mixing Ex) Seesaw mechanism Large flavor mixing （MSN matrix) “Probe of GUT scale int.” SUSY GUT Radiative correction S.Baek, T.Goto Y.Okada KO (2000)

  9. Collider vs flavor physics LHC SUSY Lagragian Mass spectrum Flavor Physics ! mixing Complementary each other

  10. b →s transitions

  11. M.Misiak&M.Steinhauser (2006) NP effects interfere with the SM GFM Add MFV

  12. MFV

  13. Not diagonal ! SUSY KO and L.Roszkowski (2001)

  14. Higgs mediated FCNC Non-holomorphic Integrate out SUSY particles NG :Flavor diagonal

  15. J.Foster, KO, L.Roszkowski (2005)

  16. P.Ball and R.Fleischer (2006) Lattice CKM angle & side

  17. MFV

  18. All combined : single insertion

  19. CP violation in CKMfitter UTfit

  20. 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 tanβregion can be covered by tCPV in radiative decay. • Combined with the spectrum measurement, such a measurement provides a clue to high energy scale.
