Lepton flavor violating decays of vector mesons in the MRSSM

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.

Automated summary

In this study, the rare decays of neutral vector mesons J/? and r(nS) are analyzed in the minimal R-symmetric supersymmetric standard model using the effective Lagrangian method. The predicted branching ratios are mainly determined by the mass insertion parameters d(ij), which are off-diagonal inputs, with comparable contributions from different parts. Considering the experimental constraints on the mass insertion parameters, the predicted branching ratios for the most promising process r(nS) ? lt are ten orders of magnitude smaller than the present experimental bounds.
