PROPERTIES OF CENTRAL CC - INTERACTIONS AT A MOMENTUM OF 4.2 GEV/C PER NUCLEON

Abstract

In this paper the multiple of secondary hadrons(π^±-mesons and protons)inСС-interactions, depending on the degree of collision centrality was studied. As the degree of centrality accepted number of protons participating formed in the event. The experimental values of the mean multiplicity π^±-mesons, protons, proton-participants identified for 4 methodically selected types of collisions. Estimate the yield of protons in different momentum intervals depending on the value of the impact parameter. The experimental data are compared with the results of theoretical calculations of the model FRITIOF. It is shown that the multiplicity of slow and evaporated protons model reproduced unsatisfactorily.
