In hypernuclear systems, interactions involving nucleons and hyperons are intricately influenced by the surrounding particles, particularly by the density and the isospin feature of the nuclear medium. In this work, the relativistic…
Using the quark-meson coupling (QMC) model, we investigate whether $\omega, \eta, \eta'$ and $D^-$ mesons form meson-nucleus bound states. Our results suggest that one should expect to find $\eta$- and $\omega$-nucleus bound states in all…
