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…

Restoration of U(1) symmetry and meson spectrum in hot or dense matter
Pedro Costa, M. C. Ruivo, C. A. de Sousa +1
We explore the effects of breaking and restoration of chiral and axial symmetries using an extended three-flavor Nambu-Jona-Lasinio model that incorporates explicitly the axial ano…
