Chiral Symmetry Restoration for Quark Matter with a Chiral Chemical Potential
(World Scientific Publ Co Pte Ltd, 2017-01-01)
In this work we study the chiral transition in quark matter at finite temperature and in the presence of a chiral imbalance in the Nambu Jona-Lasinio model. We use the Medium Separation Scheme (MSS) to rewrite divergent ...
Deconfinement and chiral restoration in nonlocal SU(3) chiral quark models
(American Physical Society, 2013-10)
We study the features of nonlocal SU(3) chiral quark models with wave function renormalization. Model parameters are determined from meson phenomenology, considering different nonlocal form factor shapes. In this context ...
QCD chiral symmetry restoration with a large number of quarks in a model with a confining propagator and dynamically massive gluons
(Elsevier B.V., 2015-05-11)
Considering a QCD chiral symmetry breaking model where the gap equation contains an effective confining propagator and a dressed gluon propagator with a dynamically generated mass, we verify that the chiral symmetry is ...
Chiral symmetry restoration and pion properties in a q-deformed NJL model

Mass dependence of the deconfinement and chiral restoration critical temperatures in nonlocal SU(2) Polyakov-Nambu-Jona-Lasinio models
(American Physical Society, 2013-01)
In the framework of nonlocal SU(2) chiral quark models with Polyakov loop, we analyze the dependence of the deconfinement and chiral restoration critical temperatures on the explicit chiral symmetry breaking driven by the ...
