Abstract

From a data sample of 183 pb-1 recorded at a center-of-mass energy of √s = 189 GeV with the OPAL detector at LEP, 3068 W-pair candidate events are selected. Assuming Standard Model W boson decay branching fractions, the W-pair production cross section is measured to be δww = 16.30 ± 0.34(stat.) ± 0.18(syst.) pb. When combined with previous OPAL measurements, the W boson branching fraction to hadrons is determined to be 68.32 ±0.61(stat.) ±0.28(syst.)% assuming lepton universality. These results are consistent with Standard Model expectations. (C) 2000 Published by Elsevier Science B.V.

N2 - From a data sample of 183 pb-1 recorded at a center-of-mass energy of √s = 189 GeV with the OPAL detector at LEP, 3068 W-pair candidate events are selected. Assuming Standard Model W boson decay branching fractions, the W-pair production cross section is measured to be δww = 16.30 ± 0.34(stat.) ± 0.18(syst.) pb. When combined with previous OPAL measurements, the W boson branching fraction to hadrons is determined to be 68.32 ±0.61(stat.) ±0.28(syst.)% assuming lepton universality. These results are consistent with Standard Model expectations. (C) 2000 Published by Elsevier Science B.V.
