  author={Vladimir V. Ezhela and S. B. Lugovsky and Oleg Zenin},
A comprehensive as of November 2003 and evaluated data compilation on sigma_tot(e+ e- --> hadrons) was used to estimate the lowest order hadronic contribution to the muon anomalous magnetic moment. The preliminary result is a_mu(had, LO) = (699.6 +- 1.9(rad) +- 2.0(proc) +- 8.5(e+e-)) * 10^-10 The Standard Model value of the muon magnetic anomaly calculated by updated SM formulae published or e-printed by November 2003 then reads a_mu = (1 165 918 3.5 +- 8.7(had) +- 4.0(LbL) +- 0.3(QED) +- 0.2…
