For the electron, wiki lists its magnetic moment as −1.00115965218076(27) μB. It does not list it for the Muon or Tau. Wiki does show for the Muon the Anomalous magnetic dipole moment of 0.00116592089. Is it correct to assume the magnetic moment of the Muon is -1.00116592089 μB? For the Tau, wiki does not show either a magnetic moment or an anomalous magnetic dipole moment. What is the magnetic moment of the Tau? A google search produces results like http://arxiv.org/pdf/hep-ph/0702027v1.pdf but unfortunately, the article is beyond my pay grade for understanding.
