On similarities of bulk observables in nuclear and particle collisions

TL;DR

This paper investigates the universal patterns in particle production across different collision types, revealing similarities in bulk observables and providing predictions for future high-energy experiments.

Contribution

It demonstrates the universality of hadroproduction processes across various collision systems and energies, with a unified approach that aligns well with existing data and extends to LHC energies.

Findings

Good agreement with measurements from AGS to RHIC energies.

Predictions for LHC energies are consistent with extrapolations.

Identifies universal regularities in bulk particle production.

Abstract

We study the regularities in the multiparticle production data obtained from different types of collisions indicating the universality of the hadroproduction process. The similarities of such bulk variables like the charged particle mean multiplicity and the pseudorapidity density at midrapidity measured in nucleus-nucleus, (anti)proton-proton and e+e- interactions are analysed according to the dissipating energy of participants and their types. This approach shows a good agreement with the measurements in a wide range of nuclear collision energies from AGS to RHIC. The predictions up to the LHC energies are made and compared to experimental extrapolations.
