Abstract

A search is made for charged Higgs bosons predicted by Two-Higgs-Doublet extensions of the Standard Model (2HDM) using electron-positron collision data collected by the OPAL experiment at √s = 189-209 GeV, corresponding to an integrated luminosity of approximately 600 pb^-1. Charged Higgs bosons are assumed to be pair-produced and to decay into qq̄ τν_τ or AW^±*. No signal is observed. Model-independent limits on the charged Higgs-boson production cross section are derived by combining these results with previous searches at lower energies. Under the assumption BR(H^± → τν_τ) + BR (H^± → qq̄) = 1, motivated by general 2HDM type II models, excluded areas on the [m_H± BR(H^± → τν_τ)] plane are presented and charged Higgs bosons are excluded up to a mass of 76. 3 GeV at 95 % confidence level, independent of the branching ratio BR(H^±→τν_τ). A scan of the 2HDM type I model parameter space is performed and limits on the Higgs-boson masses m_H± and m_A are presented for different choices of tanβ.

N2 - A search is made for charged Higgs bosons predicted by Two-Higgs-Doublet extensions of the Standard Model (2HDM) using electron-positron collision data collected by the OPAL experiment at √s = 189-209 GeV, corresponding to an integrated luminosity of approximately 600 pb-1. Charged Higgs bosons are assumed to be pair-produced and to decay into qq̄ τντ or AW±*. No signal is observed. Model-independent limits on the charged Higgs-boson production cross section are derived by combining these results with previous searches at lower energies. Under the assumption BR(H± → τντ) + BR (H± → qq̄) = 1, motivated by general 2HDM type II models, excluded areas on the [mH± BR(H± → τντ)] plane are presented and charged Higgs bosons are excluded up to a mass of 76. 3 GeV at 95 % confidence level, independent of the branching ratio BR(H±→τντ). A scan of the 2HDM type I model parameter space is performed and limits on the Higgs-boson masses mH± and mA are presented for different choices of tanβ.
