摘要：
A combined fit to R(e+e --> hadrons) in the range 5-61.4 GeV and to the data from the CERN e+e- collider LEP is presented to obtain a global estimate of the strong-interaction scale parameter LAMBDA(MS/(5)) free of uncertainties due to hadronization and choice of the momentum scale, where MSBAR denotes the modified minimal subtraction scheme. Our fitted values LAMBDA(MS/(5))=545(-182)+221 MeV, in the range 5-94 GeV, and LAMBDA(MS/(5))-961(-314)+383 MeV, in the range 14-94 GeV, do not agree, within two standard deviations, with the low-energy determinations from UPSILON branching ratios and deep-inelastic scattering.
