Dispersive estimation of the LO hadronic contribution to the muon $g-2$: fitting incompatible $e^{+}{e}^{-}$ data

V. V. Bryzgalov, O. V. Zenin

Using an up-to-date compilation of ${\sigma }_{\mathrm{tot}}(e^{+}{e}^{-}\to hadrons)$ data we estimated the LO hadronic contribution to the muon anomalous magnetic moment, $a_{\mu }(had,LO)$. Incom…
