TL;DR
This paper reviews how adding general 8-quark interactions affects vacuum properties and magnetic catalysis in an extended NJL model with SU(3) flavor symmetry, building on existing 6-quark and 3-quark interactions.
Contribution
It introduces the most general 8-quark interactions into the NJL model and analyzes their impact on vacuum properties and magnetic catalysis.
Findings
8-quark interactions significantly influence vacuum stability.
Magnetic catalysis effects are modified by 8-quark terms.
The extended model provides a more comprehensive understanding of quark interactions.
Abstract
We review the effect on vacuum properties and magnetic catalysis, of adding the most general 0-spin 8-quark (8q) interactions to the combined SU(3) flavor Nambu--Jona-Lasinio (NJL) and 6-quark (6q) 't Hooft interaction Lagrangian.
