The Nambu–Jona-Lasinio model and its extensions (PNJL, PQM, variants with vector/tensor couplings) as effective theories of chiral symmetry breaking in QCD. Claims about their phase structure, couplings, mean-field treatment, or predictions for chiral restoration and critical points belong here; lattice QCD or full QCD claims do not.

Quark-meson model calculations find bulk up-down quark matter has lower energy per baryon than strange quark matter

Repulsive vector interactions in NJL-type models can weaken or eliminate the first-order chiral transition
