论文摘要
由于最近发现Besiii和LHCB合作的奇怪的隐藏魅力异国情调的状态的动机，我们研究了两种夸克模型的$ S $ Wave奇怪的隐藏底部Tetraquark。梅森 - 梅森和diquark-antidiquark配置均已考虑。数值结果表明两个夸克模型中都没有界面状态。但是，已经预测了几个共鸣状态。找到了三个带有$ i（j^{p}）= \ frac {1} {2}（0^{+}）$的共振状态，其能量范围为$ 10479 \ sim 10550 $，$ 10528 \ sim 10632 $，$ 10597 \ sim 10597 \ sim 10681 $ mev，相应地。带有$ i（j^{p}）= \ frac {1} {2}（1^{+}）$的三个共振状态被预测位于$ 10491 \ sim 10675 $，$ 10502 \ sim 10679 $和$ 10522 \ sim 10723 $ MEV，分别位于$ 10491 \ sim 10675 $中。此外，还存在$ i（j^{p}）= \ frac {1} {2} {2}（2^{+}）$的共振，并且质量估计为$ 10531 \ sim 10680 $ mev。在LHCB中的进一步实验中，应访问本工作中所有这些预测的状态
Motivated by the recent discovery of the hidden charm exotic state with strangeness by the BESIII and LHCb Collaborations, we study the $S$ wave strange hidden bottom tetraquark in two kinds of quark models. Both meson-meson and diquark-antidiquark configurations are taken into account. The numerical results indicate that there is no bound state in both quark models. However, several resonance states have been predicted. Three resonance states with $I(J^{P})=\frac{1}{2}(0^{+})$ are found, the energy ranges of which are $10479\sim 10550$, $10528\sim 10632$, and $10597\sim 10681$ MeV, respectively. Three resonance states with $I(J^{P})=\frac{1}{2}(1^{+})$ are predicted to be located in $10491\sim 10675$, $10502\sim 10679$, and $10522\sim 10723$ MeV, respectively. Moreover, there also exist a resonance with $I(J^{P})=\frac{1}{2}(2^{+})$ and the mass is estimated to be $10531\sim 10680$ MeV. All these predicted states in the present work should be accessible for the further experiments in LHCb
