摘要：
We study the large branching ratios of B -> eta K* decays and the time- dependent CP asymmetry S-phi KS anomaly of B -> phi K-S decay in a flavor changing Z' model associated with flavor changing neutral currents at the tree level. Considering the right-handed flavor changing couplings and setting xi(LL) = xi(RL) = xi(LR) = xi(RR) = xi, we obtain 0.011 < xi < 0.0131, this parameter region could give a simultaneous explanation to these anomalies of B -> eta K* and B -> phi K-S decays. The results are consistent with the constraints and the assumptions of some references.
