Abstract：

In the framework of R-parity violating supersymmetry, we investigate the time dependent CP asymmetry S_φKSanomaly of B→φK_Sdecay. When the values of the weak phase φ in the R-parity violating coupling fall into certain parameter spaces (246°<φ<263°) we find that this anomaly can be easily explained; at the same time, the branching ratio of B→φK_Sdecay can also be in agreement with experimental measurements.
