Freeze Out

We review the chemical and kinetic freeze-out conditions in high energy heavy-ion collisions for AGS, SPS, RHIC, and LHC energies. Chemical freeze-out parameters are obtained using produced particle yields in central collisions while the corresponding kinetic freeze-out parameters are obtained using transverse momentum distributions of produced particles. For chemical freeze-out, different freeze-out scenarios are discussed such as single and double/flavor dependent freeze-out surfaces. Kinetic freeze-out parameters are obtained by doing hydrodynamic inspired blast wave fit to the transverse momentum distributions. The beam energy and centrality dependence of transverse energy per charged particle multiplicity are studied to address the constant energy per particle freeze-out criteria in heavy-ion collisions.

Step Mechanism

Experimental results on longitudinal momentum distributions of pions, protons, deuterons, tritons, and 3He produced in the interactions of 24 GeV/c protons with the Ag and Br nuclei of nuclear emulsion are presented. The variation of [Formula: see text] with the shower multiplicity, the angle of emission, and the mass of the particles has been studied. Many characteristics of pions have been found to be similar to those produced in hadron–hadron collisions. The results on pions suggest that perhaps the multiparticle production in nucleon–nucleus collisions takes place via a two-step mechanism.

High Energy Collisions

Transverse momentum distributions of final-state particles produced in soft process in proton-proton (pp) and nucleus-nucleus (AA) collisions at Relativistic Heavy Ion Collider (RHIC) and Large Hadron Collider (LHC) energies are studied by using a multisource thermal model. Each source in the model is treated as a relativistic and quantum ideal gas. Because the quantum effect can be neglected in investigation on the transverse momentum distribution in high energy collisions, we consider only the relativistic effect. The concerned distribution is finally described by the Boltzmann or two-component Boltzmann distribution. Our modeling results are in agreement with available experimental data.

Three isotropic emission fireballs are used to describe the rapidity (or pseudorapidity) and transverse momentum distributions of negatively charged particles produced in nucleus–nucleus collisions at high energy. The calculated results are compared and shown to be in agreement with the experimental data of 16O–Au, 32S–S, and 32S–Ag collisions at 200A GeV. PACS Nos.: 25.75-q, 24.10Pa

Theoretical Predictions

By taking into account the effects of thermal motion, the transverse momentum distributions of identified charged particles produced in nucleus collisions are discussed in the context of a hydrodynamic model including phase transition. A comparison is made between the theoretical predictions and experimental measurements. The theoretical model gives a good description to the data collected in Au–Au collisions at RHIC energy of [Formula: see text][Formula: see text]GeV. For Pb–Pb collisions at LHC energy of [Formula: see text][Formula: see text]TeV, the model works well up to the transverse momentum of about [Formula: see text][Formula: see text]GeV/c.
