摘要：

Standard Model contributions to the electron, muon, and tan lepton anomalous magnetic moments, al (g(l) - 2)/2, are reviewed and updated. The fine structure constant is obtained from the electron g(e) - 2 and used to refine the QED contribution to the muon g(mu) - 2. Recent advances in electroweak and hadronic effects on g(mu) - 2 are summarized. Examples of "New Physics" probed by the a(mu) Brookhaven experiment E821 are outlined. The prediction for a(tau) is also given.
