Abstract

J/ΨJ/\Psi-nuclear bound state energies are calculated for a range of nuclei by solving the Proca (Klein-Gordon) equation. Critical input for the calculations, namely the medium-modified DD and DD^* meson masses, as well as the nucleon density distributions in nuclei, are obtained from the quark-meson coupling model. The attractive potential originates from the DD and DD^* meson loops in the J/ΨJ/\Psi self-energy in nuclear medium. It appears that J/ΨJ/\Psi-nuclear bound states should produce a clear experimental signature provided that the J/ΨJ/\Psi meson is produced in recoilless kinematics.
