In-medium mass shifts of $B_{c}^{()}, B_{s}^{()}$ and $D_{s}^{(*)}$ mesons

We present our predictions for the Lorentz scalar mass shifts of two-flavored heavy mesons, $B_{c}^{(*)}, B_{s}^{(*)}$ and $D_{s}^{(*)}$ in symmetric nuclear matter. The in-medium mass shifts are estimated by evaluating the lowest order one-loop self-energies of the mesons based on a flavor-SU(5) effective Lagrangian approach. In-medium properties necessary for the estimates are calculated by the quark-meson coupling (QMC) model. The enhanced self-energies of the mesons in symmetric nuclear matter relative to those in free space, yield the negative mass shifts of these mesons.
