Abstract

Searches fur the neutral Higgs bosons predicted by the Standard Model (SM) and the Minimal Supersymmetric extension of the Standard Model (MSSM) have been performed with the OPAL detector at LEP. Approximately 170 pb-1 of e+e- collision data collected at √s ≈ 189 GeV were used to search for Higgs boson production in the SM process e+e- → H0Z0 and the MSSM processes e+e- → h0Z0 and e+e- → A0h0. The searches are sensitive to the bb̄ and τ+T- decay modes of the Higgs bosons, and also to the MSSM decay mode h0 → A0A0. OPAL search results at lower centre-of-mass energies have been incorporated in the limits, which are valid at the 95% confidence level. For the SM Higgs boson, a lower mass bound of 91.0 GeV is obtained. In the MSSM. the limits are mu > 74.8 GeV and mA > 76.5 GeV, assuming tan 3 > 1, that the mixing of the scalar top quarks is either zero or maximal, and that the soft SUSY-breaking masses are 1 TeV. For the case of zero scalar top mixing, the values of tan 3 between 0.72 and 2.10 are excluded.

abstract = "Searches fur the neutral Higgs bosons predicted by the Standard Model (SM) and the Minimal Supersymmetric extension of the Standard Model (MSSM) have been performed with the OPAL detector at LEP. Approximately 170 pb-1 of e+e- collision data collected at √s ≈ 189 GeV were used to search for Higgs boson production in the SM process e+e- → H0Z0 and the MSSM processes e+e- → h0Z0 and e+e- → A0h0. The searches are sensitive to the bb̄ and τ+T- decay modes of the Higgs bosons, and also to the MSSM decay mode h0 → A0A0. OPAL search results at lower centre-of-mass energies have been incorporated in the limits, which are valid at the 95{\%} confidence level. For the SM Higgs boson, a lower mass bound of 91.0 GeV is obtained. In the MSSM. the limits are mu > 74.8 GeV and mA > 76.5 GeV, assuming tan 3 > 1, that the mixing of the scalar top quarks is either zero or maximal, and that the soft SUSY-breaking masses are 1 TeV. For the case of zero scalar top mixing, the values of tan 3 between 0.72 and 2.10 are excluded.",

N2 - Searches fur the neutral Higgs bosons predicted by the Standard Model (SM) and the Minimal Supersymmetric extension of the Standard Model (MSSM) have been performed with the OPAL detector at LEP. Approximately 170 pb-1 of e+e- collision data collected at √s ≈ 189 GeV were used to search for Higgs boson production in the SM process e+e- → H0Z0 and the MSSM processes e+e- → h0Z0 and e+e- → A0h0. The searches are sensitive to the bb̄ and τ+T- decay modes of the Higgs bosons, and also to the MSSM decay mode h0 → A0A0. OPAL search results at lower centre-of-mass energies have been incorporated in the limits, which are valid at the 95% confidence level. For the SM Higgs boson, a lower mass bound of 91.0 GeV is obtained. In the MSSM. the limits are mu > 74.8 GeV and mA > 76.5 GeV, assuming tan 3 > 1, that the mixing of the scalar top quarks is either zero or maximal, and that the soft SUSY-breaking masses are 1 TeV. For the case of zero scalar top mixing, the values of tan 3 between 0.72 and 2.10 are excluded.
