Muon conversion to electron in nuclei within the $\mu \nu$SSM with a 125 GeV Higgs

Abstract

Within framework of the $\mu$ from $\nu$ Supersymmetric Standard Model ($\mu \nu$SSM), three exotic right-handed neutrino superfields induce new sources for lepton-flavor violation. In this work, we investigate muon conversion to electron in nuclei within the $\mu \nu$SSM in detail. With a 125 GeV Higgs, the numerical results indicate that the $\mu -e$ conversion rates in nuclei within the $\mu \nu$SSM can reach the experimental upper bound, which could be detected with the future experimental sensitivities.
