Vacuum effects on the properties of nuclear matter under an external magnetic field

The effects of the Dirac sea of nucleons are investigated within a covariant model of the hadronic interaction. I extend the usual mean field approximation and present a procedure to deal with divergences which are proportional to polynomials on the magnetic field intensity. For this purpose a nucle...
