From pp To AA Ultra-Relativistic Collisions

Detailed comparisons between pp (root s = 7 TeV), p-Pb (root s(NN) = 5.02 TeV) and Pb-Pb (root s(NN) = 2.76 TeV) collisions in terms of ratios of normalized p(T) spectra, Bjorken energy density and correlation between the kinetic freeze-out temperature (T-kin(fo)) and average transverse expansion velocity (< beta(T) >) parameters as a function of charged particle multiplicity/centrality are presented.
