We have searched for hadronic decay modes of unstable pointlike charged spin-zero particles such as charged Higgs bosons or technipions, produced in pairs in e +e − annihilation. Together with previous results on leptonic decay modes from other experiments, we conclude that at the 95% confidence level such particles do not exist in the mass range of 5 to 13 GeV.
