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+ → qq- and H+ → r+vT. 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+ → r+vT branching ratio.
