摘要：

We review the relation between the ratio of hadronic and electronic Z widths, R = GAMMA(Z --> qqBAR)/GAMMA(Z --> e+e-), and the strong coupling constant at the Z mass, alpha(s). The theoretical uncertainty of alpha(s) derived from R is estimated to be DELTAalpha(s) = +/-0.002(electroweak) +/- 0.002(QCD)-0.003(+0.004) (m(top), m(Higgs)).
