A new evaluation of the hadronic vacuum polarisation contributions to the muon anomalous magnetic moment and to $$\varvec{\alpha }({{\varvec{m}}}_{{\varvec{Z}}}^2)$$ α(mZ2)
Abstract We reevaluate the hadronic vacuum polarisation contributions to the muon magnetic anomaly and to the running of the electromagnetic coupling constant at the Z-boson mass. We include newest $$e^+e^- \rightarrow \mathrm{hadrons}$$ e+e-→hadrons cross-section data together with a phenomenologic...
