Constrains for non-standard statistical models of particle creations by identified hadron multiplicity results at LHC energies

TL;DR

This paper investigates non-standard statistical models for particle creation at LHC energies, focusing on non-extensive thermodynamics and the impact of Tsallis statistics on hadron multiplicity predictions.

Contribution

It introduces a modified thermodynamical model replacing Boltzmann with Tsallis statistics to better describe high-energy particle production.

Findings

Tsallis statistics better fit transverse momentum distributions at high energies

Heavy secondary particles and multistrange baryons are more abundant with the modified model

Suppression factors similar to quark jet fragmentation are incorporated

Abstract

We analysed the identified hadron multiplicity predictions of the modified thermodynamical model of the multiparticle production processes with non-extensive statistic. The replacement of the standard Boltzmann exponential factor by the eventually much slower falling Tsallis one is suggested by the analysis of the transverse momentum distributions measured at high energies. The increase of high transverse momenta should accord with the abundance of heavy secondary particles, in particular multistrange barions. The introduction to the thermodynamical model of suppression factors similar to the ones in a quark jet fragmentation models is discussed.
