Abstract

Recently several new bounds of the lepton flavor violating decays of the neutral vector mesons J/ψJ/\psi and Υ(nS)\Upsilon(nS) are reported from the experiments. In the work, we analyze these processes in the scenario of the minimal R-symmetric supersymmetric standard model by means of the effective Lagrangian method. The predicted branching ratios are affected by the mass insertion parameters δij\delta^{ij} and the contributions from different parts are comparable. Taking account of the constraints on the mass insertion parameters from the experiments, the branching ratios for the most promising processes Υ(nS)lτ\Upsilon(nS)\rightarrow l\tau are predicted to be ten orders of magnitude smaller than the present experimental bounds.
