Abstract
The data collected by the OPAL experiment at root s = 183 GeV used used tu search for Higgs bosons which are predicted by the Standard Model and vario us extensions, such as general models with two Higgs field doublets and the Minimal Supersymmetric Standard Model (MSSM). The data correspond to an in tegrated luminosity of approximately 54 pb(-1). None of the searches for ne utral and charged Higgs bosons have revealed an excess of events beyond the expected background. This negative outcome, in combination with similar re sults from searches at lower energies, leads to new limits for the Higgs bo son masses and other model parameters. In particular, the 95% confidence le vel lower limit fur the mass of the Standard Model Higgs boson is 88.3 GeV. Charged Higgs bosons can be excluded for masses up to 59.5 GeV. In the MSS M, m(ho) > 70.5 GeV and m(Ao) > 72.0 GeV are obtained for tan beta > if no and maximal scalar top mixing and soft SUSY-breaking masses of 1 TeV. The r ange 0.8 < tan beta < 1.9 is excluded for minimal scalar top mixing and m(t op) less than or equal to 175 GeV. More general scans of the MSSM parameter space are also considered.
