Novel two-loop SUSY effects on CP asymmetry in $B\to ϕK_{s}$

Authors

Description

Inspired by the exotic measurements on the CP asymmetry in $B\to ϕK_{s}$, we study a new diagram in supersymmetric models which can make the difference $\sin2ϕ^{eff}_{1}(J/ΨK_{s})-\sin2ϕ^{eff}_{1}(ϕK_{s})$ to be $20-50%$ after satisfying the constraint from $b\to s γ$. We also find that the direct CP asymmetry of $b\to s γ$ could be $\sim 10%$ and testable at $B$ factories.
