Phase diagram and critical properties in the Polyakov--Nambu--Jona-Lasinio model
C. A. de Sousa, Pedro Costa, M. C. Ruivo +1
We investigate the phase diagram of the so-called Polyakov--Nambu--Jona-Lasinio model at finite temperature and nonzero chemical potential with three quark flavours. Chiral and dec…
Scalar-pseudoscalar meson behavior and restoration of symmetries in SU(3) PNJL model
Pedro Costa, M. C. Ruivo, C. A. de Sousa +2
The modification of mesonic observables in a hot medium is analyzed as a tool to investigate the restoration of chiral and axial symmetries in the context of the Polyakov-loop exte…
Phase structure, critical points and susceptibilities in Nambu-Jona-Lasinio type models
C. A de Sousa, Pedro Costa, M. C. Ruivo
We investigate the chiral phase transition at finite temperature and chemical potential within SU(2) and SU(3) Nambu-Jona-Lasinio type models. The behavior of the baryon number sus…
The QCD critical end point in the PNJL model
Pedro Costa, C. A. de Sousa, M. C. Ruivo +1
We investigate the role played by the Polyakov loop in the dynamics of the chiral phase transition in the framework of the so-called PNJL model in the SU(2)sector. We present the p…
Thermodynamics and critical behavior in the Nambu-Jona-Lasinio model of QCD
Pedro Costa, M. C. Ruivo, C. A. de Sousa
We investigate the phase diagram of strongly interacting matter as a function of temperature and baryonic density/chemical potential, within Nambu--Jona-Lasinio type models. We per…
Effects of the Regularization on the Restoration of Chiral and Axial Symmetries
Pedro Costa, M. C. Ruivo, C. A. de Sousa
The effects of a type of regularization for finite temperatures on the estoration of chiral and axial symmetries are investigated within the SU(3) Nambu-Jona-Lasinio model. The reg…
