TL;DR
This paper reviews Higgs boson searches at LEP2, reporting preliminary lower mass limits for the Standard Model and MSSM Higgs particles based on data collected at 189 GeV.
Contribution
It provides the first preliminary lower mass limits for the SM and MSSM Higgs bosons from LEP2 data at 189 GeV.
Findings
SM Higgs mass lower limit of 95.5 GeV/c^2
MSSM neutral Higgs h lower limit of 83.5 GeV/c^2
MSSM neutral Higgs A lower limit of 84.5 GeV/c^2
Abstract
The status of the search at LEP2 for the Higgs in the Standard Model (SM) and in the minimal supersymmetric extension of the Standard Model MSSM) is reviewed. A preliminary lower limit of 95.5/c^2 at 95% C.L. on the SM Higgs is obtained after a preliminary analysis of the data collected at sqrt(s)= 189 GeV. For standard choices of MSSM parameter sets, the search for the neutral Higgs bosons h and A leads to preliminary 95% C.L. exclusion lower limits of 83.5GeV/c^2 and 84.5 GeV/c^2, respectively.
