The yield ratio of anti-nuclei and nuclei of relativistic nuclear collisions in the central rapidity region

TL;DR

This paper calculates the yield ratios of anti-nuclei to nuclei in relativistic nuclear collisions using a self-similarity approach, comparing results with experimental data across various energies.

Contribution

It introduces a self-similarity based method to predict anti-nuclei to nuclei yield ratios in high-energy collisions, extending previous models to include anti-particle production.

Findings

Calculated yield ratios agree with experimental data across SPS, RHIC, and LHC energies.

The approach successfully describes inclusive spectra of pions and kaons in proton-proton collisions.

Provides a unified framework for understanding particle-antiparticle production in relativistic nuclear interactions.

Abstract

This article describes calculations of the yield ratio of anti-particles to the yield of particles ($\bar{p}/p$, $\bar{d}/d$,$\overline{^{3}\mathrm{He}}$/$^{3}$He) 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.
