Resumen:
The one loop polarization insertions for the kaon and the mesons are evaluated in a hadronicmedium as functions of the field intensity and the baryonic density. For this purpose an effective chiralmodel of the hadronic interaction is used, supplemented with a phenomenological K- interaction. Thepropagators of the charged particles include the full effect of the coupling to the magnetic field, and theanomalous magnetic moments are taken into account for the baryon fields. The effective masses as well asthe decay widths are introduced and examined as functions of matter density and the magnetic intensity.
