The Yield Ratio of Anti-Nuclei and Nuclei in Relativistic Nuclear Collisions in the Central Rapidity Region

Journal of Experimental and Theoretical Physics Aims and scope Submit manuscript

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.
