# Hadronization within the Non-Extensive Approach and the Evolution of the Parameters

## TL;DR

This paper reviews how transverse momentum distributions of particles from high-energy collisions can be modeled using non-extensive statistics, revealing mass and energy scaling behaviors and parameter dependencies on collision centrality.

## Contribution

It demonstrates the effectiveness of non-extensive distributions in fitting particle spectra and explores the evolution of spectral parameters with collision conditions.

## Key findings

- Mass and energy scaling are more explicit for heavier hadrons.
- Temperature and Tsallis q parameter show linear dependence on collision centrality.
- Non-extensive models fit the data well across different collision systems.

## Abstract

We review transverse momentum distributions of various identified charged particles stemming from high energy collisions fitted by various non-extensive distributions as well as by the usual Boltzmann-Gibbs statistics. We investigate the best-fit formula with the obtained $\chi^2/ndf$ values. We find that the physical mass and $\sqrt{s}$ scaling become more explicit with heavier produced hadrons in both proton-proton and heavy-ion collisions. The spectral shape parameters, in particular the temperature $T$ and the non-extensive Tsallis parameter $q$, do exhibit an almost linear dependence with the centrality-dependence in heavy-ion collisions.
