Hadronic accompaniment of free quarks creation in E{sup +}E{sup -}-collisions

Technical Report:

Abstract

The process of free b-quarks quarks creation in e{sup +}e{sup -}-annihilation at the Z{sup 0}-peak is regarded. The hadronic accompaniment due to bremsstrahlung of such a process is analysed. The calculations for free bb-bar-pair production are made taking into account the energy losses on colour field. The distributions of leptons and free light quarks from weak decays of b-quark are shown. The probability to overlap of ionization signals of free light quark and charge hadron is estimated. The comparison with LEP experimental data allows to get a conclusion, that the existing experimental accuracy does not exclude the creation of free b-quarks in the Z{sup 0}-decays. 17 refs.; 6 figs.
