In this paper, we investigate decays in the framework of the RPV SUSY model. We discuss the tree-level contribution of the sparticles and to these decay branching ratios. In the two channels, the -mediated channel is more sensitive to the parameter product than the -mediated channel to . And the parameter product is severely constrained to the order of by the experiment data with , which is one order of magnitude more stringent than before. In the calculation of hadronic matrix elements, the resonant effects are large than those of nonresonant terms. Especially, the resonant contribution of scalar meson f(980) plays a dominate role in -mediated channel. [ABSTRACT FROM AUTHOR]
