Exotic molecular meson states of $B^{(\ast )}{K}^{(\ast )}$ nature

E. Oset, L. Roca

We evaluate theoretically the interaction of the open bottom and strange systems $\bar{B}\bar{K}$, ${\bar{B}}^{\ast }\bar{K}$, $\bar{B}{\bar{K}}^{\ast }$ and ${\bar{B}}^{\ast }{\bar{K}}^{\ast }$ to look for possible bou…
