摘要：

From an analysis of multi-hadron events from Z0 decays, values of the strong coupling constant alpha-s(M(Z0)2) = 0.131 +/- 0.006(exp) +/- 0.007(theor.) and alpha-s(M(Z0)2) = 0.117(-0.009)+0.007(exp.)-0.002(+0.006)(theor.) are derived from the energy-energy correlation distribution and its asymmetry, respectively, assuming the QCD renormalization scale-mu = M(Z0). The theoretical error accounts for differences between O(alpha-s)2 calculations. A two parameter fit of Lambda(MS) and the renormalization scale-mu leads to Lambda(MS) = 216 +/- 85 MeV and mu-2/s - 0.027 +/- 0.013 or to alpha-s(M(Z0)2) = 0.117(-0.008)+0.006(exp.) for the energy-energy correlation distribution. The energy-energy correlation asymmetry distribution is insensitive to a scale change: thus the alpha-s value quoted above for this variable includes the theoretical uncertainty associated with the renormalization scale.
