Indication of a Differential Freeze-Out in Proton-Proton and Heavy-Ion Collisions at RHIC and LHC Energies

Figure 17

Fitting of invariant spectra with Tsallis distribution including radial flow using (8) for [19, 20], [19, 20], and [19, 20] in most peripheral Pb + Pb collisions at = 2.76 TeV; symbols represent the data points and the line is the fit function.
