Description
We calculate the $D_s$-, $B$-, $D$- and $K$-nucleus bound state energies and coordinate space radial wave functions by solving the Klein-Gordon equation in momentum space.
The attractive strong potentials for the mesons in nuclei are calculated from the mass shifts of these mesons in nuclear matter in the local density approximation.
The mass shift of the $B$, $D$, and $K$ mesons are calculated within the quark-meson coupling (QMC) model.
This negative mass shift may be regarded as a signature of partial restoration of chiral symmetry in an empirical sense, because the origin of the negative mass shift in the study is not
directly related to the chiral symmetry mechanism.
