Analysis of U(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(1) symmetry using an extended three-flavor Nambu-Jona-Lasinio model that incorporates explicitly the axial anomaly…
