| dc.description | The electron and muon number violating muonium-antimuonium oscillation process in an extended Minimal Supersymmetric Standard Model is investigated. The Minimal Supersymmetric Standard Model is modified by the inclusion of three right-handed neutrino superfields. While the model allows the neutrino mass terms to mix among the different generations, the sneutrino and slepton mass terms have only intra-generation lepton number violation but not inter-generation lepton number mixing. So doing, the muonium-antimuonium conversion can then be used to constrain those model parameters which avoid further constraint from the $μ\to eγ$ decay bounds. For a wide range of parameter values, the contributions to the muonium-antimuonium oscillation time scale are at least two orders of magnitude below the sensivity of current experiments. However, if the ratio of the two Higgs field VEVs, $\tanβ$, is very small, there is a limited possibility that the contributions are large enough for the present experimental limit to provide an inequality relating $\tanβ$ with the light neutrino mass scale $m_ν$ which is generated by see-saw mechanism. The resultant lower bound on $\tanβ$ as a function of $m_ν$ is more stringent than the analogous bounds arising from the muon and electron anomalous magnetic moments as computed using this model. | |
