$J\mathrm{/}\mathrm{\Psi }$ mass shift and $J\mathrm{/}\mathrm{\Psi }$-nuclear bound state

We calculate mass shift of the $J\mathrm{/}\mathrm{\Psi }$ meson in nuclear matter arising from the modification of $DD,D{D}^{\ast }$ and $D^{\ast }{D}^{\ast }$ meson loop contributions to the $J\mathrm{/}\mathrm{\Psi }$ self-energy. The estimate includes the in-medium $D$ and $D^{\ast }$ meson masses consistently. The $J\mathrm{/}\mathrm{\Psi }$ mass shift (scalar potential) calculated is negative (attractive), and complementary to the attractive potential obtained from the QCD color van der Waals forces. Some results for the $J\mathrm{/}\mathrm{\Psi }$-nuclear bound state energies are also presented.
