| 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 we learned from the recent theoretical and phenomenological developments: transverse momentum spectra and azimuthal anisotropy (v2) of charge averaged pions and kaons 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 bulk or from the Quark-Gluon Plasma (soft yields). The hadron spectra in both types of yields are approximated by the Tsallis-Pareto like distribution, and parameters q & T provided information on the system's 'soft' and 'hard' components.
