Abstract

We present a possible supersymmetric solution to the discrepancy between the observed mixing CP asymmetries in B\ensuremath→\ensuremathφK_S and B\ensuremath→\ensuremathη^\ensuremath'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_\ensuremathφK_S\ensuremath≠S_\ensuremathη^\ensuremath'K_S. We also consider the proposed mechanisms to solve the puzzle of the observed large branching ratio of B\ensuremath→\ensuremathη^\ensuremath'K and their impact on S_\ensuremathη^\ensuremath'K_S.
