On Pseudorapidity Distribution and Speed of Sound in High Energy Heavy Ion Collisions Based on a New Revised Landau Hydrodynamic Model

Figure 1

Pseudorapidity distributions of charged particles produced in Au-Au collisions at  GeV with different centrality percentages. The circles and curves represent the experimental data quoted in [22] and our calculated results, respectively. In the calculation, spectator contributions in Figures 1(e)–1(j) are not counted, and there is no spectator being expected in Figures 1(a)–1(d).
