Hadron spectra measured in high-energy collisions present distribution 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,;:ital even in heavy-ion coil:is:4)ns. Here, we present what can was learnt from the recent theoretical and phenomenological developments: transverse momentum spectra and azimuthal anisotropy (v(2)) of charge averaged pions, kaons and protons stemming from central Pb 1 Ph collisions at root s = 2.76 AfeV 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.
