Query: Supersymmetric Model of Muon Anomalous Magnetic Moment and Neutrino
  Masses   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.
