The bottomed strange molecules with isospin 0

Abstract

Using the local hidden gauge approach, we study the possibility of the existence of bottomed strange molecular states with isospin 0. We find three bound states with spin-parity $0^{+}$, $1^{+}$ and $2^{+}$ generated by the ${\bar{K}}^{\ast }{B}^{\ast }$ and $\omega B_s^{\ast }$ interaction, among which the state with spin 2 can be identified as $B_{s2}^{\ast }(5840)$. In addition, we also study the ${\bar{K}}^{\ast }B$ and $\omega B_s$ interaction and find a bound state which can be associated to $B_{s1}(5830)$. Besides, the $\bar{K}{B}^{\ast }$ and $\eta B_s^{\ast }$ and $\bar{K}B$ and $\eta B_s$ systems are studied, and two bound states are predicted. We expect that further experiments can confirm our predictions.
