Hadronic Vacuum Polarization Contribution to the Anomalous Magnetic Moments of Leptons from First Principles

We compute the leading, strong-interaction contribution to the anomalous magnetic moment of the electron, muon, and tau using lattice quantum chromodynamics (QCD) simulations. Calculations include the effects of u, d, s, and c quarks and are performed directly at the physical values of the quark masses and in volumes of linear extent larger than 6 fm. All connected and disconnected Wick contractions are calculated. Continuum limits are carried out using six lattice spacings. We obtain aeLO-HVP=189.3(2.6)(5.6)×10-14, aμLO-HVP=711.1(7.5)(17.4)×10-10 and aτLO-HVP=341.0(0.8)(3.2)×10-8, where the first error is statistical and the second is systematic.
