Journal ArticleDOI
Muon g − 2 and α ( M Z 2 ) : A new data-based analysis
TL;DR: In this paper, the authors presented a complete reevaluation of the hadronic vacuum polarization contributions to the anomalous magnetic moment of the muon, aμhad,VP, and Δαhad(MZ2), from the combination of e+e-→hadrons cross section data.
Journal ArticleDOI
g − 2 of charged leptons, α ( M Z 2 ) , and the hyperfine splitting of muonium
TL;DR: In this paper, the authors presented 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 to the running of the QED coupling at the mass scale of the Z$ boson.
Journal ArticleDOI
Data-driven evaluations of Euclidean windows to scrutinize hadronic vacuum polarization
Gilberto Colangelo,A. El-Khadra,Martin Hoferichter,Alexander Keshavarzi,Christoph Lehner,Peter Stoffer,Thomas Teubner +6 more
TL;DR: In this article , windows in Euclidean time are used to isolate the origin of potential conflicts between evaluations of the hadronic-vacuum-polarization (HVP) contribution to the anomalous magnetic moment of the muon in lattice QCD and from e+e−→hadrons cross-section data.
Journal ArticleDOI
Strong coupling from e + e - →hadrons below charm
Diogo Boito,Maarten Golterman,Maarten Golterman,Alexander Keshavarzi,Kim Maltman,Kim Maltman,Daisuke Nomura,Santiago Peris,Thomas Teubner +8 more
TL;DR: In this paper, a new compilation of the hadronic $R$-ratio from available data for the process was used to determine the strong coupling, and the results were in good agreement with a recent determination from the OPAL and ALEPH data for hadronic $\ensuremath{\tau}$ decays.
Journal ArticleDOI
g − 2 of the muon: status report
TL;DR: A short review of the status of the anomalous magnetic moment of the muon, g − 2, is given in this paper, with emphasis on recent developments in different sectors and the accuracy of the Standard Model prediction.
