摘要: Abstract The total cross section for e + − annihilation into hadrons has been measured CM energies ranging from 50 to 57 GeV. We fit the predictions of standard model these measurements and those at lower energies. mass Z 0 boson, M , QCD scale parameter, Λ MS are derived fit. results =88.6 −1.8 +2.0 GeV/ c 2 =0.15 −0.11 +0.16 GeV .
