Abstract

Quantum Chromodynamics(QCD) is the basic theory of strongly interaction,  and the most significant feature of QCD are spontaneous chiral symmetry  broken and color confinement in vacuum. It is believed that there will be chiral phase transition and deconfinement phase transition from hadronic matter to quark-gluon-plasma (QGP) at sufficiently high temperature and from nuclear matter to quark matter at high baryon density. The hot QGP as well as hot and dense quark matter can be created in heavy ion collision, for example, at RHIC and LHC, while the cold and dense quark matter may exist in the inner core of compact stars, for example, neutron star.

In this talk, I will introduce QCD phase diagram, heavy ion collision and the relation between neutron star and EoS of strongly interacting matter. And also, I will introduce effective model, e.g., Nambu—Jona-Lisinio(NJL) mode and NJL-like models.
