Abstract

The data collected at centre-of-mass energies ranging from 130 to 172 GeV by ALEPH at LEP, corresponding to an integrated luminosity of 27.5 pb^-1, are analysed in a search for pair-produced charged Higgs bosons H^±. Three analyses are employed to select the τ⁺ν_ττ^-ν̄ _τ, cs̄τ^-ν̄_τ and cs̄sc̄ final states. No evidence for a signal is found. Mass limits are set as a function of the branching fraction ℬ(τν) for H^± → τν. Charged Higgs bosons with masses below 52 GeV/c² are excluded at 95% C.L. independently of ℬ(τν), thus significantly improving on existing limits.

N2 - The data collected at centre-of-mass energies ranging from 130 to 172 GeV by ALEPH at LEP, corresponding to an integrated luminosity of 27.5 pb-1, are analysed in a search for pair-produced charged Higgs bosons H±. Three analyses are employed to select the τ+νττ-ν̄ τ, cs̄τ-ν̄τ and cs̄sc̄ final states. No evidence for a signal is found. Mass limits are set as a function of the branching fraction ℬ(τν) for H± → τν. Charged Higgs bosons with masses below 52 GeV/c2 are excluded at 95% C.L. independently of ℬ(τν), thus significantly improving on existing limits.
