We have searched for the pair produced charged Higgs particles in the decays of Z 0 for the decay channels of H +H -→τ +ντ -ν̄, H +H -→τνcs and H +H -→cs̄c̄s. The data sample analyzed corresponds to approximately 50 000 hadronic decays of Z 0. 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.

Abstract
We have searched for the pair produced charged Higgs particles in the decays of Z 0 for the decay channels of H +H -→τ +ντ -ν̄, H +H -→τνcs and H +H -→cs̄c̄s. The data sample analyzed corresponds to approximately 50 000 hadronic decays of Z 0. 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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
