Freeze-Out Conditions in High-Energy Heavy-Ion Experiments

High-energy heavy-ion collisions are unique tool to produce hot and dense matter called Quark Gluon Plasma (QGP). The fireball produced in these collisions thermalizes quickly leading to expansion and cooling of the system. The chemical and kinetic freeze-out parameters provide important information regarding the fireball produced in these collisions. We present the chemical and kinetic freeze-out parameters obtained at AGS, SPS, RHIC, and LHC energies. The beam energy dependence of transverse energy per charged particle multiplicity is also presented. We discuss the implications of these results.
