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 $\ddot{I}{ƒ}_{\mathrm{tot}}(e^{+}{e}^{-}\to hadrons)$ data we estimated the LO hadronic contribution to the muon anomalous magnetic moment, $a_{\hat{I}}¼(had,LO)$. Inc…
