Chromomagnetic Catalysis of Chiral Symmetry Breaking and Color Superconductivity

TL;DR

This paper demonstrates how external chromomagnetic fields can induce chiral and color symmetry breaking in quark matter, potentially affecting color superconductivity, within an extended NJL model framework.

Contribution

It introduces the concept that chromomagnetic fields can catalyze symmetry breaking and influence color superconductivity in quark matter, extending previous NJL model studies.

Findings

Chromomagnetic fields induce symmetry breaking at weak quark attraction.

External fields may significantly impact color superconductivity formation.

Chromomagnetic catalysis occurs even under minimal interaction conditions.

Abstract

It is shown in the framework of an extended NJL model with two flavors that some types of external chromomagnetic field induce the dynamical chiral or color symmetry breaking even at weakest attraction between quarks. It is argued also that an external chromomagnetic field, simulating the chromomagnetic gluon condensate of the real QCD-vacuum, might significantly influence the color superconductivity formation.
