Abstract

We present results for the η_c-nucleus bound state energies for various nuclei using an effective Lagrangians approach. The attractive potentials for the η_c in the nuclear medium originate from the medium-modified intermediate D D^* state in the η_c self energy, using the local density approximation. Our results suggest that the η_c should form bound states with all the nuclei considered
