${\eta }_c$-nucleus bound states

Abstract

${\eta }_c$-nucleus bound state energies are calculated for various nuclei. Essential input for the calculations, namely the medium-modified $D$ and $D^{\ast }$ meson masses, as well as the density distributions in nuclei, are calculated within the quark-meson coupling (QMC) model. The attractive potentials for the ${\eta }_c$ meson in the nuclear medium originate from the in-medium enhanced $D{D}^{\ast }$ loops in the ${\eta }_c$ self-energy. Our results suggest that the ${\eta }_c$ meson should form bound states with all the nuclei considered.
