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…
Phase transitions in quark matter and behaviour of physical observables in the vicinity of the critical end point
Pedro Costa, C. A. de Sousa, M. C. Ruivo +1
We study the chiral phase transition at finite and within the framework of the SU(3) Nambu-Jona-Lasinio (NJL) model. The QCD critical end point (CEP) and the critical lin…
The QCD critical end point in the SU(3) Nambu--Jona-Lasinio model
Pedro Costa, C. A. de Sousa, M. C. Ruivo +1
We study the chiral phase transition at finite temperature and baryonic chemical potential within the framework of the SU(3) Nambu-Jona-Lasinio (NJL) model. The QCD criti…
Analysis of U(1) symmetry-breaking and restoration effects on the scalar-pseudoscalar spectrum
Pedro Costa, M. C. Ruivo, C. A. de Sousa +1
We explore patterns of effective restoration of the chiral U(1) symmetry using an extended three-flavor Nambu-Jona-Lasinio model that incorporates explicitly the axial anomaly…
Restoration of U(1) symmetry and meson spectrum in hot or dense matter
Pedro Costa, M. C. Ruivo, C. A. de Sousa +1
We explore the effects of breaking and restoration of chiral and axial symmetries using an extended three-flavor Nambu-Jona-Lasinio model that incorporates explicitly the axial ano…
