Abstract
We consider the possibility to detect the Higgs boson signal in the pr ocess e+e- --> ZbbBAR at LEP200 energies. The calculations are perform ed in the tree approximation for complete set of diagrams, including n ot 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 i nvariant mass distribution.
