| dc.description | In this article, we calculate the masses and decay constants of the $P$-wave strange-bottomed mesons $B_{s0}$ and $B_{s1}$ with the QCD sum rules, and observe that the central values of the masses of the $B_{s0}$ and $B_{s1}$ are smaller than the corresponding $BK$ and $B^*K$ thresholds respectively, the strong decays $B_{s0}\to BK$ and $B_{s1}\to B^*K$ are kinematically forbidden. They can decay through the isospin violation precesses $B_{s0}\to B_sη\to B_sπ^0$ and $B_{s1}\to B_s^*η\to B_s^*π^0$. The bottomed mesons $B_{s0}$ and $B_{s1}$, just like their charmed cousins $D_{s0}(2317)$ and $D_{s1}(2460)$, maybe very narrow. | |
