Dependence of Temperatures and Kinetic Freeze-Out Volume on Centrality in Au-Au and Pb-Pb Collisions at High Energy

Figure 7

Dependence of (a, b) effective temperature on the rest mass and (c, d) mean transverse momentum on the mean energy or mean moving mass for (a, c) Au-Au collisions at 200 GeV and (b, d) Pb-Pb collisions at 2.76 TeV in different centrality classes. The lines are the results fitted for the values of derived quantities.
