摘要：
A global analysis of the e + e - --> hadrons data is presented to extract an effective value for the strong-interaction correction to the quark-parton-model approximation to be used for the Z hadronic width. We obtain GAMMA-h = 1782 +/- 17(fit) +/- 15[electroweak (EW) theory] MeV, and a ratio GAMMA-h/GAMMA-l = 21.32 +/- 0.24, in good agreement with the results from the CERN collider LEP, and different from the two-loop QCD predictions, GAMMA-h = 1735 +/- 6(alpha-s) +/- 15(EW theory) MeV and GAMMA-h/GAMMA-l = 20.74 +/- 0.12, corresponding to LAMBDA-MS(5) = 140(-80)+100 MeV, where MSBAR denotes the modified minimal-subtraction scheme.
