First Order Quark-Hadron Phase Transition in the NJL-Type Nuclear and Quark Model
arXiv:1003.2843 · doi:10.1143/PTP.123.1013
Abstract
The quark-hadron phase transition at finite baryon chemical potential is investigated in the extended Nambu-Jona-Lasinio model in which the scalar-vector eight-point interaction is included holding the chiral symmetry. By comparing a pressure of the symmetric nuclear matter with that of the quark matter, the realized phase at given baryon density is determined. As a result, the first order quark-hadron phase transition is derived where the deconfinement transition occurs after the chiral symmetry restoration in this model.
