Varying interaction strength in DSE/BSE models produces meson degeneracies whose domains shrink with model realism, linked to quark propagator pole locations and possible chiral spin symmetry.

Kinetic mixing terms are introduced in the parity-doublet model to reproduce the empirical axial charge g_A ≈ 1.28 of the nucleon along with masses of the nucleon and N*(1535).
QCD at high T has three phases differing in symmetries, degrees of freedom and N_c scaling: hadron gas below T_ch, stringy fluid between T_ch and T_d, and quark-gluon plasma above T_d.
