On pseudorapidity distribution in p -Pb and Xe–Xe collisions at high energy based on the three-source Landau hydrodynamic model

We used the three-source Landau hydrodynamic model to describe the pseudorapidity distributions of charged particles produced in p-Pb collisions and Xe–Xe collisions at LHC energies. The research results fit well with the experimental data which are measured by ALICE collaboration at LHC. The related parameters are obtained and analyzed. Moreover, in most cases, we consider that the central source undergoes the change of the hadronic gas to QGP...
