主 题:Anomalous magnetic moment muon running coupling hadronic contributions
摘 要:We update our Standard Model predictions for g-2 of the muon and for the hadronic contributions (5) 2 to the running of the QED coupling, Δαbad^5)(MZ^2). Particular emphasis is put on recent changes in the hadronic contributions from new data in the 2π channel and from the energy region just below 2 GeV.
