${\pi }_0$ pole mass calculation in a strong magnetic field and lattice constraints

Sidney S. Avancini, Ricardo L. S. Farias, Marcus Benghi Pinto +2

The ${\pi }_0$ neutral meson pole mass is calculated in a strongly magnetized medium using the SU(2) Nambu-Jona-Lasinio model within the random phase approximation (RPA) at zero tempera…
