Eta, Omega and Charmed Mesic Nuclei

Abstract

Using the quark-meson coupling (QMC) model, we investigate theoretically whether $\eta$ and $\omega$ mesons form meson-nucleus bound states. We study several nuclei from ${}^6$He to ${}^{208}$Pb, including those which are the final nuclei in the proposed experiment at GSI. Results for the $\omega$ are compared with those of the Walecka model. Our results suggest that one should expect to find $\eta$- and $\omega$-nucleus bound states in all these nuclei. Furthermore, we investigate the possibility of charmed mesic nuclei. It is shown that the $D^{-}$ meson will inevitably form narrow bound states with ${}^{208}$Pb.
