Abstract
The Dirac equation explained why the gyromagnetic ratio, g factor, is equal to 2 for fundamental spin [Formula: see text] particles. Quantum loop effects were subsequently shown to induce a small shift or anomaly, a≡(g-2)/2. Anomalous magnetic moment effects have been calculated and measured with extraordinary precision for the electron and muon. Here, the Standard Model's predictions for al=(gl-2)/2, l=e, μ are described and compared with experimental values. Implications for probing "New Physics" effects are also discussed.
