摘要：

We consider the possibility to detect the Higgs boson signal in the process e+e- --> ZbbBAR at LEP200 energies. The calculations are performed in the tree approximation for complete set of diagrams, including not only the signal (e+e- --> HZ --> ZbbBAR) and the main background (e+e- --> ZZ --> ZbbBAR) contributions, but also additional background (for instance, Z emission from the b-quark line) and interference terms. We calculate the Higgs signal in the total cross section and bbBAR invariant mass distribution.
