Abstract
Improved values for the two- and three-loop mass-dependent QED contributions to the anomalous magnetic moments of the electron, muon, and tau are presented. The Standard Model prediction for the electron (g-2) is compared with its new measured value, providing the best determination of the fine-structure constant to date: alpha^(-1) = 137.035 999 709 (96) [0.70 ppb].
