A possible supersymmetric solution to the discrepancy between B -> ϕKₛ and B -> η' Kₛ CP asymmetries

الأصل · EN

We present a possible supersymmetric solution to the discrepancy between the observed mixing CP asymmetries in B -> ϕKₛ and B -> η' Kₛ. We show that due to the different parity in the final states of these processes, their supersymmetric contributions from the R-sector have an opposite sign, which naturally explain the large deviation between Sϕₖₛ and Sη' ₖₛ. We also consider the proposed mechanisms to solve the puzzle of the observed large branching ratio of B -> η' K and study their impact on Seta' Kₛ.
