摘要：

In this study, we analyze the rare decays of the neutral vector mesons J/? and r(nS) in the scenario of the minimal R-symmetric supersymmetric standard model using the effective Lagrangian method. The predicted branching ratios are dominated by the mass insertion parameters d(ij), i.e., the off-diagonal inputs, and the contributions of different parts are comparable. Taking into account the experimental constraints on the mass insertion parameters, the predicted branching ratios for the most promising processes r(nS) ? lt are ten orders of magnitude smaller than the present experimental bounds.
