Can Tsallis Distribution Fit All the Particle Spectra Produced at RHIC and LHC?

Figure 6

The data are from [33, 53–55] for Pb + Pb at  TeV. The red dashed line is the results fitting the low region and the blue dotted-dashed line is the results fitting the high region using (10). The solid curves are the analytical results with (12). The corresponding fitting parameters and /ndf are given in Table 2. For a better visualization both the data and the analytical curves have been scaled by a constant as indicated. The ratios of data/fit are shown at the bottom.
