| dc.description | 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(EW)) * 10^-10. This result deviates from the current experimental world average of a_mu by (-19.5 +- 9.6(theor) +- 8.0(exp)) * 10^-10, i.e. at 1.5 sigma level. | |
