Description

The report presents the results of the development of the approach to the study of relativistic nuclear interactions in the four-velocitiy space using the similarity principle.
The essence of the modification of the self-similar approach consists in the inclusion of quark-gluon dynamics in the generation of hadrons in the nuclear-nuclear interactions in the central rapidity region. Inclusive spectra of pions and kaons produced in p+p and nuclear-nuclear collisions were studied as functions of their transverse momentum pT in the central rapidity region, calculated within the framework of a modified approach based on the assumption of similarity of inclusive hadron spectra. A satisfactory description of the NA61/SHINE data for the ratios of the K+/π+ and K−/π− yields as functions of √s in p+p and Be+Be collisions is also presented. The results of calculations of the yield ratios of antiparticles to the yields of particles (anti-p/p, anti-d/d, anti-3He/3He) in proton-proton and nuclear-nuclear interactions using the similarity parameter in the central rapidity region are presented and compared with world experimental data.
