Lepton anomalous magnetic moments - a theory update
Abstract
Standard Model contributions to the electron, muon, and tau lepton anomalous magnetic moments, al=(gl-2)/2, are reviewed and updated. The fine structure constant is obtained from the electron ge-2 and used to refine the QED contribution to the muon gmu-2. Recent advances in electroweak and hadronic effects on gmu-2 are summarized. Examples of ``New Physics'' probed by the amu Brookhaven experiment E821 are outlined. The prediction for atau is also given.
