π0 pole mass calculation in a strong magnetic field and lattice constraints
The π0 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 temperature and zero baryonic density. We employ a magnetic field dependent coupling, G(eB), fitted to reproduce lattice QCD resul...
