Hadronic molecules with both open charm and bottom

With the one-boson-exchange model, we study the interaction between the S-wave $D^{(\ast )}\mathrm{/}{D}_s^{(\ast )}$ meson and S-wave $B^{(\ast )}\mathrm{/}{B}_s^{(\ast )}$ meson considering the S-D mixing effect. Our calculation indicates that there may exist the $B_c$-like molecular states. We estimate their masses and list the possible decay modes of these $B_c$-like molecular states, which may be useful to the future experimental search.
