论文摘要
我们研究了筛选的非贵族夸克模型和$^3p_0 $模型中$ b_s $介子的质谱和衰减属性。我们的结果表明，$ b_ {sj}（6064）$和$ b_ {sj}（6114）$状态作为最近LHCB测量的第一个解决方案，可以解释为$ b_s（1^3d_3）$和$ b_s和$ b_s（1^3d_1）$。此外，$ b_ {sj}（6109）$和$ b_ {sj}（6158）$状态作为LHCB测量的第二个解决方案，可以解释为$ b'_ _ {s2}（1d）$和$ b_ {s1}（s1}（2p）$。同时，$ b_ {s1}（5830）$可以解释为$ b_ {s1}（1p）$的候选者。我们还计算了具有预测群体的其他激发$ b_s $介子的衰减属性，这对将来的实验搜索有帮助。
We investigate the mass spectrum and the decay properties of the $B_s$ mesons within the screened nonrelativistic quark model and the $^3P_0$ model. Our results suggest that the $B_{sJ}(6064)$ and $B_{sJ}(6114)$ states, as the first solution of the recently LHCb measurements, could be explained as the $B_s(1^3D_3)$ and $B_s(1^3D_1)$, respectively. In addition, the $B_{sJ}(6109)$ and $B_{sJ}(6158)$ states, as the second solution of the LHCb measurements, could be explained as the $B'_{s2}(1D)$ and $B_{s1}(2P)$, respectively. Meanwhile, the $B_{s1}(5830)$ could be interpreted as the candidate of the $B_{s1}(1P)$. We also calculated the decay properties of the other excited $B_s$ mesons with the predicted masses, which should be helpful for the experimental searching in future.
