Abstract

A future Z-factory will offer the possibility of studying rare Z decays , such as those leading to lepton flavor violation (LFV) final states. In this work, by considering the constraints from radiative two-body decays , we investigate the LFV decays in the framework of the Minimal R-symmetric Supersymmetric Standard Model with two benchmark points from the existing literature. The flavor-violating off-diagonal entries , and are constrained by the current experimental bounds of . Considering recent experimental constraints, we also investigate Br( ) as a function of . The numerical results show that the theoretical predictions of Br( ) in the MRSSM are several orders of magnitude below the current experimental bounds. The LFV decays and may be promising observation targets in future experiments.
