Description

Knowledge of the hadronic contribution to the photonic vacuum polarization is required for calculating radiative corrections in electroweak theory. A simple model is proposed that reproduces the value α-bar≡α(m2Z) obtained by integrating experimental data on the transition σe+e-→hadrons. High-accuracy measurement of the muon magnetic moment would refine the parameters of our model in the energy range 1 GeV<E<2 GeV, which is crucial for reducing errors in α-bar
