Abstract

Data collected at centre-of-mass energies of 181–184 GeV by ALEPH at LEP, corresponding to an integrated luminosity of 56.9 pb−1, are analysed in a search for pair-produced charged Higgs bosons H±. Three analyses are employed to select the View the MathML source, View the MathML source/View the MathML source and View the MathML source final states. No evidence for a signal is found. Mass limits are set as a function of the branching fraction B(H+→τ+ντ). Under the assumption that the decay modes considered cover the totality of the possible final states, charged Higgs bosons with masses below 59 GeV/c2 are excluded at 95% C.L. independently of B(H+→τ+ντ).
