dc.descriptionExperimental data on multiplicities and kinematical characteristics of $π^-$, $π^+$ mesons and protons in the interactions of protons with carbon nucleus at momentum 4.2 GeV/c in a dependence of collision centrality are analyzed. Parameter Q which is a difference between multiplicities of positive and negative charged particles without multiplicity of slow protons with momentum less than 0.3 GeV/c in an event, is taken as a criteria of collision centrality. The experimental data on events with different centrality are compared with predictions of the cascade-evaporation model and the modified FRITIOF model. For the first time, non-nucleonic degrees of freedom in nuclei ($Δ^+, Δ^0 $ isobars) are taken into account in the FRITIOF model, and a commonly good description of the secondary particles characteristics is reached.
