Description
Hadron spectra measured in high-energy collisions present distributions which can
be derived from the non-extensive statistical and thermodynamical phenomena. Based on
earlier theoretical developments, it seems, the methods are very applicable for jets hadronization processes in electron-positron, proton-proton, and even in heavy-ion collisions.
Here, we present what can was learnt from the recent theoretical and phenomenological
developments: transverse momentum spectra and azimuthal anisotropy (v2) of charge averaged
pions, kaons and protons stemming from high-energy collisions form RHIC to LHC energies, which are described analytically in a ‘soft + hard’ model.
In this model, we propose that hadron yields produced in heavy-ion collisions are simply
the sum of yields stemming from jets (hard yields) in addition to the yields originating from the Quark-Gluon Plasma (soft yields). The hadron spectra in both types of yields are approximated by the Tsallis – Pareto like distribution
