- W2992198325 abstract "We calculate $gensuremath{-}2$ of the muon and the QED coupling $ensuremath{alpha}{(M}_{Z}^{2}),$ by improving the determination of the hadronic vacuum polarization contributions and their uncertainties. We include the recently reanalyzed CMD-2 data on ${e}^{+}{e}^{ensuremath{-}}ensuremath{rightarrow}{ensuremath{pi}}^{+}{ensuremath{pi}}^{ensuremath{-}}.$ We carefully combine a wide variety of data for the ${e}^{+}{e}^{ensuremath{-}}$ production of hadrons and obtain the optimum form of $R(s)ensuremath{equiv}{ensuremath{sigma}}_{mathrm{had}}^{0}(s)/{ensuremath{sigma}}_{mathrm{pt}}(s),$ together with its uncertainty. Our results for the hadronic contributions to $gensuremath{-}2$ of the muon are ${a}_{ensuremath{mu}}^{mathrm{h}mathrm{a}mathrm{d},mathrm{L}mathrm{O}}=(692.4ifmmodepmelsetextpmfi{}{5.9}_{mathrm{exp}}ifmmodepmelsetextpmfi{}{2.4}_{mathrm{rad}})ifmmodetimeselsetexttimesfi{}{10}^{ensuremath{-}10}$ and ${a}_{ensuremath{mu}}^{mathrm{h}mathrm{a}mathrm{d},mathrm{N}mathrm{L}mathrm{O}}=(ensuremath{-}9.8ifmmodepmelsetextpmfi{}{0.1}_{mathrm{exp}}ifmmodepmelsetextpmfi{}{0.0}_{mathrm{rad}})ifmmodetimeselsetexttimesfi{}{10}^{ensuremath{-}10},$ and for the QED coupling $ensuremath{Delta}{ensuremath{alpha}}_{mathrm{had}}^{(5)}{(M}_{Z}^{2})=(275.5ifmmodepmelsetextpmfi{}{1.9}_{mathrm{exp}}ifmmodepmelsetextpmfi{}{1.3}_{mathrm{rad}})ifmmodetimeselsetexttimesfi{}{10}^{ensuremath{-}4}.$ These yield $(gensuremath{-}2)/2=0.00116591763(74),$ which is about $2.4ensuremath{sigma}$ below the present world average measurement, and $ensuremath{alpha}{(M}_{Z}^{2}{)}^{ensuremath{-}1}=128.954ifmmodepmelsetextpmfi{}0.031.$ We compare our $gensuremath{-}2$ value with other predictions and, in particular, make a detailed comparison with the latest determination of $gensuremath{-}2$ by Davier et al." @default.
