Eta, Omega and Charmed Mesic Nuclei
Abstract
Description
Using the quark-meson coupling (QMC) model, we investigate theoretically whether $η$ and $ω$ 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 $ω$ are compared with those of the Walecka model. Our results suggest that one should expect to find $η$- and $ω$-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.
