Strange mesons in nuclei and neutron stars

Abstract

The present status in the field of strange mesons in nuclei and neutron stars is reviewed. In particular, the $\bar{K}N$ interaction, that is governed by the presence of the $\Lambda (1405)$, is analyzed and the formation of the $\bar{K}NN$ bound state is discussed. Moreover, the properties of $\bar{K}$ in dense nuclear matter are studied, in connection with strangeness production in nuclear collisions and kaon condensation in neutron stars.
