Impact of eight quark interactions on chiral phase transitions II: Thermal effects

TL;DR

This paper investigates how eight-quark interactions influence the thermal behavior of chiral phase transitions within an extended NJL model, considering both idealized and realistic quark mass scenarios.

Contribution

It introduces the effects of eight-quark interactions on thermal properties in the NJL model with 't Hooft interaction, expanding understanding of chiral phase transitions.

Findings

Eight-quark interactions significantly affect thermal properties.

Both massless and realistic quark mass cases are analyzed.

Results enhance understanding of chiral symmetry restoration.

Abstract

In this talk attention is drawn to thermal properties due to the addition of eight quark interactions in the standard $SU(3)\times SU(3)$ chiral Nambu-Jona-Lasinio model (NJL) with 't Hooft interaction (NJLH). The schematic SU(3) flavor limit with massless current quarks as well as the realistic case $m_u=m_d\ne m_s$ are discussed.
