A Description of Pseudorapidity Distributions of Charged Particles Produced in Au+Au Collisions at RHIC Energies

Figure 3

The pseudorapidity distributions of charged particles produced in different centrality Au+Au collisions at  GeV. The solid dots are the experimental measurements [5]. The dashed, dashed-dotted, and dotted curves are, respectively, the contribution from pions, kaons, and protons got from the hydrodynamic results of (18). The solid curves are the sums of the three types of curves.
