    "abstract": "Isospin effects on the optical potentials of kaons and antikaons in dense\nhadronic matter are investigated using a chiral SU(3) model. These effects are\nimportant for asymmetric heavy ion collision experiments. In the present work\nthe dispersion relations are derived for kaons and antikaons, compatible with\nthe low energy scattering data, within our model approach. The relations result\nfrom the kaonic interactions with the nucleons, vector mesons and scalar mesons\nin the asymmetric nuclear matter. The isospin asymmetry effects arising from\nthe interactions with the vector-isovector $\\rho$- meson as well as the scalar\nisovector $\\delta$ mesons are considered. The density dependence of the isospin\nasymmetry is seen to be appreciable for the kaon and antikaon optical\npotentials. This can be particularly relevant for the future accelerator\nfacility FAIR at GSI, where experiments using neutron rich beams are planned to\nbe used in the study of compressed baryonic matter.",
