Analysis of U $_{A}$ (1) symmetry-breaking and restoration effects on the scalar-pseudoscalar spectrum

Pedro Costa, M. C. Ruivo, C. A. de Sousa +1

We explore patterns of effective restoration of the chiral U $_{A}$ (1) symmetry using an extended three-flavor Nambu-Jona-Lasinio model that incorporates explicitly the axial anomaly…

Two photon decay of $π^{0}$ and $η$ at finite temperature and density

Pedro Costa, M. C. Ruivo, Yu. L. Kalinovsky

A comparative study of the anomalous decays $π^{0}, η \to γ γ$ , at finite temperature and at finite density, is performed in the framework of the three--flavor Nambu--Jona-Lasinio. The…

Anomalous decay of pion and eta at finite temperature

Pedro Costa, M. C. Ruivo, Yu. L. Kalinovsky

We study the anomalous decays $π^{0}, η \to γ γ$ in the framework of the three--flavor Nambu--Jona-Lasinio [NJL] model at finite temperature. The similarities and differences between th…
