Abstract

A search is described to detect charged Higgs bosons via the process e+e-→H+H-, using data collected by the OPAL detector at center-of-mass energies of 130-172 GeV with a total integrated luminosity of 25 pb-1. The decay channels are assumed to be H+→qq̄ and H+-→ τ+vτ. No evidence for charged Higgs boson production is observed. The lower limit for its mass is determined to be 52 GeV at 95% confidence level, independent of the H+→τ+vτ branching ratio. © 1998 Published by Elsevier Science B.V. All rights reserved.
