Abstract
We study leptonic decays D_s\to τνand B^+ \to τνin R-parity violating (RPV) supersymmetric standard model. The interference between the s-channel slepton exchange and the t-channel squark exchange diagrams could be destructive in a certain model parameter region so that sizable RPV couplings are allowed. Contributions from the RPV interactions to the final states with the lepton flavor violation (LFV), τν_μ(τν_e), are also examined taking account of constraints on the RPV couplings from the other LFV processes.
