AbstractIn this paper, we investigate tau(-) -> e(-)(mu(-))K (K) over bar (K(K)over bar> = K+ K-, K-0 (K-0) over bar) decays in the framework of the RPV SUSY model. We discuss the tree-level contribution of the sparticles (v) over bar and (u) over bar to these decay branching ratios. In the two channels, the (v) over bar -mediated channel is more sensitive to the parameter product vertical bar lambda'(*)(i22)vertical bar lambda i(31(2))| than the (u) over bar -mediated channel to vertical bar lambda'(i(2))j(2)(*)lambda(3j2)'vertical bar. And the parameter product | lambda'(i(2))j(2)(*)lambda(3j2)' | is severely constrained to the order of O( 10-5) by the experiment data with m((v) over bar)= 100 GeV, 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 (v) over bar -mediated channel.
