Abstract
Following updates in the compilation of data, this work presents reevaluations of the hadronic vacuum polarization contributions to the anomalous magnetic moments of the electron (), muon () and tau lepton (), to the ground-state hyperfine splitting of muonium and also updates the hadronic contributions to the running of the QED coupling at the mass scale of the boson, . Combining the results for the hadronic vacuum polarization contributions with recent updates for the hadronic light-by-light corrections, the electromagnetic and the weak contributions, the deviation between the measured value of and its Standard Model prediction amounts to , corresponding to a muon discrepancy of .
