Abstract
The paper is devoted to the theoretical study of particle production in the Large Hadron Collider (LHC) Xe+Xe collisions at the energy s N N = 5 . 44 TeV. The description of common bulk observables, such as mean charged particle multiplicity, particle number ratios, and p T spectra, is obtained within the integrated hydrokinetic model, and the simulation results are compared to the corresponding experimental points. The comparison shows that the model is able to adequately describe the measured data for the considered collision type, similarly as for the cases of Pb+Pb LHC collisions and top Relativistic Heavy Ion Collider (RHIC) energy Au+Au collisions, analyzed in our previous works.
Highlights
The study of particle production in relativistic heavy-ion collisions is important for understanding the dynamics of the evolution of hot and dense systems formed in these processes
In the recent papers [1,2,3], the integrated hydrokinetic model [4] w√as applied to the description of particle production in Au+A√u collisions at the top√Relativistic Heavy Ion Collider (RHIC) energy sNN = 200 GeV and Pb+Pb collisions at the Large Hadron Collider (LHC) energies sNN = 2.76 TeV and sNN = 5.02 TeV
In order to simulate the process of matter evolution during a high-energy heavy-ion collision, we utilized the integrated hydrokinetic model [2,4]
Summary
The study of particle production in relativistic heavy-ion collisions is important for understanding the dynamics of the evolution of hot and dense systems formed in these processes. The analysis of the particle momentum spectra, particle yields, and particle number ratios shows in particular that a successful description of the data can be reached in the model even using different equations of state for quark-gluon matter at the hydrodynamics stage of expansion, if the initial energy-density profile is correspondingly rescaled.
