Abstract:
According to the Minimal Standard Model and the Extended Standard Model with two Higgs doublets, we calculated the total cross sections and differential cross sections for the e+e—→bb Z0 and tt-Z0 at the LEP Ⅱ and NLC energies in order tO study the possible observational effects of the Higgs particle. We found that the observation for the e+e—→bb Z0 can give the information on the Higgs particle as long as the mass of the Higgs particle MH≤140GeV. However, for the e+e—→tt-Z0 the effect from Higgs particle will be completely suppressed by the electrowead background and cannot be observed, no matter whether the Higgs particle is heavy or light.
