Novel two-loop SUSY effects on CP asymmetry in Bto φ K_(s)

Inspired by the exotic measurements on the CP asymmetry in $B\to \phi K_{s}$, we study a new diagram in supersymmetric models which can make the difference $\sin2\phi^{eff}_{1}(J/\Psi K_{s})-\sin2\phi^{eff}_{1}(\phi K_{s})$ to be $20-50%$ after satisfying the constraint from $b\to s \gamma$. We also find that the direct CP asymmetry of $b\to s \gamma$ could be $\sim 10%$ and testable at $B$ factories.
