Abstract

Within the framework of cold magnetized SU(2) Nambu-Jona-Lasinio model we evaluate the [Formula: see text] and [Formula: see text] pole mass, as well as, [Formula: see text], [Formula: see text] at zero baryon density. We employ a magnetic field dependent coupling, [Formula: see text], fitted to reproduce lattice QCD results for the quark condensates. In particular, we find that the [Formula: see text] meson mass systematically decreases when the magnetic field increases, in good agreement with recent lattice calculations.
