Abstract

Searches for the neutral Higgs bosons h0 and A0 are used to obtain limits on the Type II Two Higgs Doublet Model (2HDM(II)) with no CP-violation in the Higgs sector and no additional particles besides the five Higgs bosons. The analysis combines approximately 170 pb-1 of data collected with the OPAL detector at √s ≈ 189 GeV with previous runs at √s ≈ mz and √s ≈ 183 GeV. The searches are sensitive to the h0, A0 → qq̄, gg, τ+τ- and h0 → A0 A0 decay modes of the Higgs bosons. For the first time, the 2HDM(II) parameter space is explored in a detailed scan, and new flavour independent analyses are applied to examine regions in which the neutral Higgs bosons decay predominantly into light quarks ..
