摘要：

A search for the minimal standard model Higgs boson has been performed with data from e+e- collisions in the OPAL detector at LEP. The analysis is based on 825 nb-1 of data taken at centre-of-mass energies between 88.3 and 95.0 GeV. The search concentrated on the reactions e+e-→(e+e- or μ+μ- or vv)H0,H0→(qq or τ+τ-), for Higgs masses above 3 GeV/c2. No Higgs boson candidates have been observed. The present study excludes the existence of a standard model H0 with mass in the range 3.0≤mH≤19.3 GeV/c2 at the 95% confidence level. © 1990.
