${η}^{′}$ and $η$ mesons at high $T$ when the ${U}_{A}(1)$ and chiral symmetry breaking are tied

${η}^{′}$ and $η$ mesons at high $T$ when the ${U}_{A}(1)$ and chiral symmetry breaking are tied
Davor Horvatić, Dalibor Kekez, Dubravko Klabučar
The approach to the ${η}^{′}\text{−}η$ complex employing chirally well-behaved quark-antiquark bound states and incorporating the non-Abelian axial anomaly of QCD through the generalization of the Witten-Veneziano relation is extended to finite temperatures. Employing the chiral condensate has led t...
