Abstract (data abstract)
CERN-LEP. Measurement of the hadronic and leptonic cross sections and their forward-backward asymmetries in Z0 decay. Data come from 450 000 Z0 decays in the 1990 and 1991 running periods. The following parameters are deduced from the data.. M(Z) = 91.187 +- 0.009 GeV. WIDTH(Z) = 2.486 +- 0.012 GeV. HADRONIC WIDTH(Z) = 1.725 +- 0.012 GeV. LEPTONIC WIDTH(Z) = 83.01 +- 0.52 MeV. INVISIBLE WIDTH(Z) = 512 +- 10 MeV. GV**2 = (1.47 +- 0.51)E-3. GA**2 = (0.2483 +- 0.0016). MASS(TOP) = 115 +52,-82(EXPT) +23,-24(HIGGS) GeV. SIN2TW = 0.2339 +- 0.0015(EXPT) +0.0001,-0.0004(HIGGS).
