Cold magnetized quark matter phase diagram within a generalized SU(2) NJL model

TL;DR

This paper investigates how intense magnetic fields influence the phase diagram of cold, strongly interacting quark matter using an extended SU(2) NJL model, considering flavor mixing, vector interactions, and conditions relevant to compact stars.

Contribution

It introduces an extended NJL model incorporating flavor mixing, vector interactions, and astrophysical conditions to study magnetic effects on quark matter phases.

Findings

Magnetic fields significantly alter the phase structure of quark matter.

Charge neutrality and beta equilibrium impact the phase transitions.

Leptons' behavior is analyzed under strong magnetic fields.

Abstract

We study the effect of intense magnetic fields on the phase diagram of cold, strongly interacting matter within an extended version of the Nambu-Jona-Lasinio model that includes flavor mixing effects and vector interactions. Different values of the relevant model parameters in acceptable ranges are considered. Charge neutrality and beta equilibrium effects, which are specially relevant to the study of compact stars, are also taken into account. In this case the behavior of leptons is discussed.
