Abstract

Inspired by the exotic measurements on the CP asymmetry in B\ensuremath→\ensuremathφK_s, we study a new diagram in supersymmetric models which can make the difference sin2\ensuremathφ₁^eff(J/\ensuremathΨK_s)\ensuremath-sin2\ensuremathφ₁^eff(\ensuremathφK_s) to be 20\ensuremath-50% after satisfying the constraint from b\ensuremath→s\ensuremathγ. We also find that the direct CP asymmetry of b\ensuremath→s\ensuremathγ could be \ensuremath∼10% and testable at B factories.
