Chemical and thermal freeze-out of identified hadrons at the LHC

Abstract

This proceeding briefly summarizes our recent VISHNU hybrid model investigations on the chemical and thermal freeze-out of various hadrons species in 2.76 A TeV Pb+Pb collisions. Detailed analysis on the evolution of particle yields and the last elastic collisions distributions during the hadronic evolution reveals that the two multi-strange hadrons, $\Xi$ and $\Omega$, experience early chemical and thermal freeze-out when compared with other hadron species.
