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 0→Z 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 0→Z 0* H 0,v $$\bar v$$ ore + e − or µ+µ−),h 0 →q $$\bar q$$ andZ 0→h 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.
