Description
In this talk preliminary results of Higgs boson searches at LEP2 up to centre-of-mass energies of 183 GeV have been summarised. The main topics are searches for the Minimal Standard Model (MSM) Higgs boson and searches for neutral Higgs bosons of the Minimal Supersymmetric Standard Model (MSSM). No indication for Higgs production has been found. The experiments have published their Higgs search results for √(s)=133 GeV up to √(s)=172 GeV. A preliminary combination of these results yields a mass limit on the Standard Model Higgs boson of 77.5 GeV/c2 at 95% CL. During the winter conferences 1998 first results of the 1997 data taking at √(s)=183 GeV have been presented. Individual limits of the experiments on the MSM Higgs boson mass are around 85 GeV/c2, while benchmark mass limits on the light scalar and the pseudoscalar Higgs bosons within the MSSM are between 70 GeV/c2 and 75 GeV/c2. Other searches cover the charged Higgs boson production and Higgs decays into invisible final states
