Abstract

A search for minimal standard model (MSM) and minimal supersymmetric model (MSSM), Higgs bosons with masses larger than 3 GeV/c2 has been performed by the OPAL collaboration one + e data from LEP corresponding to an integrated luminosity of 1.24 pb−1. The limits for MSM Higgs bosons have been obtained using the channelsZ 0Z 0* H 0,Z 0*→(v \(\bar v\) ore + e or µ+, µ. The search for MSSM Higgs bosons has been performed using the channelsZ 0Z 0* H 0,v \(\bar v\) ore + e or µ+µ),h 0q \(\bar q\) andZ 0h 0 A 0,h 0 A 0→(4 jet orτ + τ → or 4τ), whereh 0 andA 0 are the two lightest neutral MSSM Higgs bosons. No Higgs boson signal has been observed. The MSM Higgs boson is excluded in the mass range 3 GeV <\(m_{H^0 }\)<25.3 GeV/c2 at the 95% confidence level; limits on the masses of the two lightest neutral MSSM Higgs bosons are obtained forh 0 mases up to 40.5 GeV/c2.
