Abstract

Non-extensive thermodynamics is a novel approach in the field of high energy physics. The low and intermediate transverse momentum spectra are extremely well reproduced by a Tsallis-Pareto distribution. However, the derivation of the Tsallis parameter is still an unsolved question. Understanding hadronization processes in heavy-ion collisions requires more detailed tests, especially at high transverse momenta, where we are far from the thermal equilibrium state. Here we focus on parton fragmentation processes at the final state, we analyze whether standard power-law-tailed fragmentation functions do overlap with Tsallis -Pareto energy distributions, reproducing experimental data. Moreover, we investigated a possible QCD evolution of the parameters.
