Chiral Transition

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 momentum integrals that appear in the model in such way that we can conciliate results obtained with the model and recent lattice results for the chiral transition.

Njl Model

An extended NJL model with [Formula: see text] and (qq)-interactions is studied at finite temperature and baryon number density. We investigate the chiral symmetry breaking, its restoration and the behavior of meson and diquark masses, decay and coupling constants as functions of T and µ.
