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

Abstract

We present a possible supersymmetric solution to the discrepancy between the observed mixing CP asymmetries in B -> ϕK_S and B -> η' K_S. 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 S_{ϕK_S} and S_{η' K_S}. 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 S_{eta' K_S}.
