Abstract

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.
