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 ...

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 ...

We discuss two aspects of charmonium in medium. First, we present results of a recent study that compares the phenomenology of charmonium spectroscopy using smooth and sudden string breaking potentials. Next, we present ...

Chiral-symmetry restoration is usually discussed in the context of quark matter, a system of deconfined quarks. However, many systems like stable nuclei and neutron stars have quarks confined within nucleons. In the present ...
