利用局域隐规范方法，研究了存在同位旋为0的底奇异分子态的可能性。我们发现由$\bar{K}^*B^*$和$\omega B_s^*$相互作用产生的三个自旋宇称为$0^+$、$1^+$和$2^+$的束缚态，其中自旋为2的束缚态可以确定为$B_{s2}^*（5840）$。此外，我们还研究了$\bar{K}^*B$和$\omega B_s$相互作用，发现了一个与$B_{s1}（5830）$相关联的束缚态。此外，还研究了$\bar{K}B^*$和$\eta B_s^*$以及$\bar{K}B$和$\eta B_s$系统，预测了两个束缚态。我们希望进一步的实验能够证实我们的预测。
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 $\bar{K}^*B^*$ and $\omega B_s^*$ interaction, among which the state with spin 2 can be identified as $B_{s2}^*(5840)$. In addition, we also study the $\bar{K}^*B$ and $\omega B_s$ interaction and find a bound state which can be associated to $B_{s1}(5830)$. Besides, the $\bar{K}B^*$ and $\eta B_s^*$ 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.
