Hadron Spectra Parameters within the Non-Extensive Approach

High Energy Physics - Phenomenology 2019-05-23 v1

Abstract

We investigate how the non-extensive approach works in high-energy physics. Transverse momentum (pTp_T) spectra of several hadrons are fitted by various non-extensive momentum distributions and by the Boltzmann--Gibbs statistics.~It is shown that some non-extensive distributions can be transferred one into another.~We find explicit hadron mass and center-of-mass energy {scaling both in the temperature and in the non-extensive parameter, qq,} in proton--proton and heavy-ion collisions. We find that the temperature depends linearly, but the Tsallis qq follows a logarithmic dependence on the collision energy in proton--proton collisions. In the nucleus--nucleus collisions, on~the other hand, TT and qq correlate linearly, as was predicted in our previous work.
