Restoration of axial symmetry and its possible relation with restoration of chiral symmetry and deconfinement at finite temperature
M. C. Ruivo, Pedro Costa, C. A. de Sousa
The phase transitions characterized by deconfinement and restoration of chiral symmetry as well as the restoration of axial symmetry, at finite temperature, are investigated in the…
Effects of entanglement and instanton suppression at finite temperature in a SU(2) EPNJL model with anomaly
M. C. Ruivo, Pedro Costa, C. A. de Sousa
We investigate the phase transitions characterized by deconfinement and restoration of chiral and axial symmetries,at finite temperature, in the framework of QCD inspired models. W…
Some properties of two Nambu--Jona-Lasinio -type models with inputs from lattice QCD
P. Costa, C. A. de Sousa, M. C. Ruivo +3
We investigate the phase diagram of the so-called Polyakov--Nambu--Jona-Lasinio (PNJL) model at finite temperature and nonzero chemical potential. The calculations are performed in…
The QCD Critical End Point in the Context of the Polyakov--Nambu--Jona-Lasinio Model
Pedro Costa, C. A. de Sousa, 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 flavors. Chiral and deco…
Interplay between chiral and axial symmetries in a SU(2) Nambu--Jona-Lasinio Model with the Polyakov loop
M. C. Ruivo, M. Santos, Pedro Costa +1
We consider a two flavor Polyakov--Nambu--Jona-Lasinio (PNJL) model where the Lagrangian includes an interaction term that explicitly breaks the U anomaly. At finite tempera…
Phase diagram and critical properties within an effective model of QCD: the Nambu-Jona-Lasinio model coupled to the Polyakov loop
Pedro Costa, M. C. Ruivo, C. A. de Sousa +1
We investigate the phase diagram of the so-called Polyakov--Nambu--Jona-Lasinio model at finite temperature and non-zero chemical potential with three quark flavors. Chiral and dec…
