摘要：

In this work, the behavior of transverse momentum (PT) and maximum PT (PTmax) distribution of light-flavored hadrons, produced in deuteron-carbon (dC) interactions at 4.2A GeV/c, is presented. We use the data, provided by the Laboratory of High Energy (LHE) with propane bubble chamber of 2 m of the Joint Institute for Nuclear Research (JINR), Dubna Russia. The results of the experimental data are compared with the predictions of the cascade model, Dubna version. Three regions in terms of the (PT)-distributions trend are observed for all types of particles, where (PT) similar to 1 and 1.5 GeV/c are the limiting values for pions and protons, respectively, in the region-III, for which the (PT) > 0.375 GeV/c. The protons' contribution to this region is an order of magnitude more than of the mesons and the distribution of the latter decreases faster than of the former. The model cannot predict the experimental results in the region-III, completely, where the number of particles is less than in the experiment.
