Chiral Transition Within Effective Quark Models under Strong Magnetic Fields

TL;DR

This paper investigates how strong magnetic fields influence the chiral phase transition in quark matter using the SU(2) NJL model, highlighting effects on chiral symmetry breaking and restoration at finite temperature and density.

Contribution

It applies the SU(2) NJL model to analyze the impact of magnetic fields on the QCD chiral transition, providing new insights into magnetic catalysis effects.

Findings

Magnetic fields enhance chiral symmetry breaking.

Chiral symmetry is restored at higher temperatures/densities.

Results suggest magnetic fields significantly affect the QCD phase diagram.

Abstract

In the recently years it has been argued that spectators in heavy ion collisions are responsible for creating a strong magnetic field that could play an important role in the QCD phase transition. In this work we use the SU(2) Nambu--Jona-Lasinio (NJL) model in order to study the chiral transition in quark matter subject to a strong magnetic field. We show some results involving the breaking of chiral symmetry and its restoration at finite temperature and density.
