Abstract
We have searched for the pair produced charged Higgs particles in the decays of Z0 for the decay channels of H+H-→τ+ντ- ν, H+H-→τνcs and H+H-→cscs. The data sample analyzed corresponds to approximately 50 000 hadronic decays of Z0. A lower limit of 36.5 GeV is obtained at the 95% confidence level for the mass of charged Higgs particle, independent of its decay branching ratio.
