| 英文摘要 | We study the QCD corrections to the calculated values of sigma(e(+) e(-) --> ZH --> ZB (b) over bar), and find that for M-H < 100 GeV, the process can be measured at the LEP energy to extract information of Higgs and the QCD corrections are negligible, namely the tree-level calculation is sufficiently accurate for the energy range, while for M-H > 100 GeV the Higgs-involved subprocess can only be investigated at NLC, and then the QCD correction becomes as large as 45%. For M-H > 2m(t), considering the subprocess e(+)e(-) --> ZH --> Zt (t) over bar, the QCD corrections are also important and must be taken into account for the cross section evaluation. |
