Abstract

We analyze the lepton flavor violating process μe\mu-e conversion in the framework of the minimal R-symmetric supersymmetric standard model. The theoretical predictions are determined by considering the experimental constraint on parameter δ12\delta^{12} from the lepton flavor violating decay μeγ\mu\rightarrow e \gamma. The numerical results show that γ\gamma penguins and Z penguins dominate the predictions on CR(μe\mu-e,Nucleus), and the contributions from Higgs penguins and box diagrams are insignificant. The theoretical predictions on conversion rate CR(μe\mu-e,Nucleus) in a Al or Ti target can be enhanced close to the future experimental sensitivities and are very promising to be observed in near future experiment.
