Abstract

Searches for the neutral Higgs bosons h(0) and A(0) 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 roots approximate to 189 GeV with previous runs at roots approximate to m(Z) and roots approximate to 183 GeV. The searches are sensitive to the h(0), A(0) --> q (q) over bar, gg. tau (+)tau (-) and h(0) --> A(0)A(0) 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 or gluons. Model-independent limits are also given.
