摘要：

We present a possible supersymmetric solution to the discrepancy between the observed mixing CP asymmetries in B-->phiK(S) and B-->eta(')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 opposite signs, which naturally leads to S(phiKS)not equalS(eta)(')K(S). We also consider the proposed mechanisms to solve the puzzle of the observed large branching ratio of B-->eta(')K and their impact on (SetaKS)-K-'.
