Inspired by the exotic measurements on the CP asymmetry in B → φKs, we study a new diagram in supersymmetric models which can make the difference sin2φ1eff (J/ΨKs) - sin2φ1eff (φKs) to be 20 - 50% after satisfying the constraint from b → sγ. We also find that the direct CP asymmetry of b → sγ could be ∼10% and testable at B factories.
