As a result, the extended NJL phase diagram is obtained in the temperature-baryon chemical potential plane and the effects of the scalar-vector coupling constant G_{sv}^q on the chiral phase transition are summarized. It is shown that a quarkyonic-like phase in which the chiral symmetry is restored but the elementary excitation modes are nucleonic appears just before deconfinement in this model. | Description: | 15 pages, 12 figures | URI: | https://hdl.handle.net/10316/109794 | ISSN: | 2050-3911 | DOI: | 10.1093/ptep/pts055 | Rights: | openAccess |
