Abstract: | The medium modifications of the energies of kaons and antikaons in isospin asymmetric hyperonic matter are investigated using
a chiral SU(3) model. The isospin-dependent medium effects are important for asymmetric heavy-ion collision experiments, as well as relevant
for the neutron star phenomenology as the bulk matter in the interior of the neutron star is highly isospin asymmetric. The
effects of hyperons on the medium modifications of the kaons and antikaons in the strange hadronic matter are investigated
in the present work and are seen to be appreciable for hadronic matter with large strangeness fractions. The study of the
K -mesons in the asymmetric strange hadronic matter can be especially relevant for the compressed strange baryonic matter which
can result from asymmetric heavy-ion collision experiments in the future accelerator facility FAIR at GSI. |
