Abstract.

The one loop polarization insertions for the kaon and the \(\phi\) mesons are evaluated in a hadronic medium as functions of the field intensity and the baryonic density. For this purpose an effective chiral model of the hadronic interaction is used, supplemented with a phenomenological K-\(\phi\) interaction. The propagators of the charged particles include the full effect of the coupling to the magnetic field, and the anomalous magnetic moments are taken into account for the baryon fields. The effective masses as well as the decay widths are introduced and examined as functions of matter density and the magnetic intensity.
