Muon conversion to electron in nuclei in Minimal R-symmetric Supersymmetric Standard Model

Abstract

We analyze the lepton flavor violating process $\mu -e$ conversion in the framework of the minimal R-symmetric supersymmetric standard model. The theoretical predictions are determined by considering the experimental constraint on parameter ${\delta }^{12}$ from the lepton flavor violating decay $\mu \to e\gamma$. The numerical results show that $\gamma$ penguins and Z penguins dominate the predictions on CR($\mu -e$,Nucleus), and the contributions from Higgs penguins and box diagrams are insignificant. The theoretical predictions on conversion rate CR($\mu -e$,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.
