  The article is devoted to the searches for new particles predicted by physics
beyond the Standard Model through the b-tagging algorithm. The dependence of
b-tagging efficiency on the jet identification, impact parameter
identification, secondary vertex identification, kinematic cuts is studied with
the help of computer programs Pythia 8.2 and Fastjet 3.3.0. The selection
criteria for kinematic parameters, their ratios for an optimal result on the
reconstruction of the vertices of heavy particles are found.
