Abstract
This article describes calculations of the yield ratio of anti-particles to the yield of particles (\(\bar {p}\)/p, \(\bar {d}\)/d, \(\overline {^{3}{\text{He}}} \)/3He) in proton–proton and nuclear–nuclear interactions using the self-similarity parameter in the central rapidity region. The used approach is based on the study of relativistic nuclear interactions in the four-velocity space. The results of the calculations are compared with the existing experimental data in a wide center-of-mass energy range (SPS, RHIC, LHC). Within this approach the inclusive spectra of pions and kaons and ratios of their yields in pp collisions have been successfully described earlier.
