Supersymmetric Model of Muon Anomalous Magnetic Moment and Neutrino Masses

Abstract

We propose the novel lepton-number relationship $L_{\tau }=L_e+L_{\mu }$, which is uniquely realized by the interaction $({\hat{\nu }}_e\hat{\mu }-\hat{e}{\hat{\nu }}_{\mu }){\hat{\tau }}^c$ in supersymmetry and may account for a possibly large muon anomalous magnetic moment. Neutrino masses (with bimaximal mixing) may be generated from the spontaneous and soft breaking of this lepton symmetry.
