“…Then, we can use (3) to describe the pseudorapidity distribution of charged particles produced in a given source. For a distribution in the full phase space, we need a modified Landau hydrodynamic model which contains four components corresponding to four sources in collisions [33]. The four sources are the target spectator/participant and projectile participant/spectator, respectively.…”

In framework of combing the participant-spectator model and the Landau hydrodynamic model, the pseudorapidity distributions of charged particles produced in heavy-ion (or nucleus-nucleus) collisions at RHIC and LHC energies are described by a modified Landau hydrodynamic model, where the Landau hydrodynamic model is applied to the target/projectile spectators and the target/projectile participants, respectively. The modeling results are in agreement with the PHOBOS and ALICE experimental data. Then, the values of square speed of sound (cs2) for the participants and spectators can be obtained from the widths of charged particle pseudorapidity distributions. Some features ofcs2for different centralities and center-of-mass energies are obtained too.
