Supersymmetric contributions to the CP asymmetry of the B > phi K_S and B > eta' K_S
Abstract
We analyse the CP asymmetry of the B > phi K_S and B > eta' K_S processes in general supersymmetric models. We show that chromomagnetic type of operator may play an important role in accounting for the deviation of the mixing CP asymmetry between B > phi K_S and B > J/psi K_S processes observed by Belle and BABAR experiments. We also show that due to the different parity in the final states of these processes, their supersymmetric contributions from the Rsector have an opposite sign, which naturally explain the large deviation between their asymmetries.
