  6. Possible Solutions • NP contribution • Right-handed current operator [Kagan (2004)] • R-parity violating terms[Y.D.Yang et.al (2004)] • non-universal Z’ [C.H.Chen & HH (2006)] • Tensor operators • [P.K.Das & K.C.Yang(2004), Y.D.Yang(2006)] • combined model analysis [K.C.Yang & HH (this talk)] • SM • Large Charm Penguin[Bauer et.al, 2003] • Uncertainty of the form factor (A0) [H.N.Li, et.al, 2004] • Large Annihilation [Kagan(2004), Beneke et.al(2006)] • (Note : In pQCD, fL≳0.75 [H.N.Li, et.al]) SI2007, Fuji-Yoshida, Japan

  12. NP contributions(preliminary) B→Kη(‘): B→φK* SI2007, Fuji-Yoshida, Japan

  13. NP contributions(2) (modified current OPs) SI2007, Fuji-Yoshida, Japan

  14. SI2007, Fuji-Yoshida, Japan

  15. Results-1(preliminary) Annihilation can resolve the puzzle NP can resolve, too Kη needs NP effects SI2007, Fuji-Yoshida, Japan

  18. Summary(preliminary) • Combined Numerical analysis of B→φK* and B→η(‘)K in MSSM by using Fierz transformations between b->sss operators • There are solutions of scalar-tensor NP parameters which explainB→η’K and B→φK* simultaneously. • Magnitude of NP OP is constrained by Br(B→Kη) • Small fL is mainly explained by annihilation effect.
