Freeze-Out of Strange Hadron in pp, pPb and PbPb Collisions at LHC Energies

摘要

167.1 Introduction Heavy ion collisions at Large Hadron Collider (LHC) and Relativistic Heavy Ion Collider (RHIC) are performed to create and study the properties of Quark Gluon Plasma (QGP). The p_T spectra of the hadrons is useful tools to study the particle production mechanisms, thermalization and collective effects and at high p_T probe jet quenching effects. Three types of the collision processes such as pp, pPb and PbPb are performed to study about the different aspects of the particle production at different center of mass energies at LHC.
