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

Figure 2

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 result of (18). The dotted-star curves are the components of leading particles obtained from (23). The solid curves are the sums of the four types of curves.
