Abstract:
We propose the novel lepton-number relationship Lτ=Le + Lμ, which is uniquely realized by the interaction (ν̂eμ̂ - êμ̂μ in supersymmetry and may contribute to the muon anomalous magnetic moment. Neutrino masses (with bimaximal mixing) may be generated from the spontaneous and soft breaking of this lepton symmetry.
