在新观察到的共振的刺激下，我们研究了夸克对生成模型中低位单底重子的强烈衰变。考虑到它们的质量和衰变模式，我们暂时将这些状态指定为模式、、和状态，然后估计它们的强衰变宽度。与LHCb Collaboration测量的实验总宽度和衰变模式相比，the 和 可以分别合理地澄清为 和 状态，而其他规范分配则不受欢迎。还提出了其他低洼底部态，其中各种窄态可能在未来的大型强子对撞机实验中具有良好的观察潜力。
Stimulated by the newly observedandresonances, we investigate the strong decays of the low-lying singly bottom baryons within the quark pair creation model. Considering their masses and decay modes, we tentatively assign these states as the-mode,,, andstates and then estimate their strong decay widths. Compared with the experimental total widths and decay modes measured by the LHCb Collaboration, theandcan be reasonably clarified into theandstates, respectively, while other canonical assignments are disfavored. Other low-lying bottom states are also presented, where various narrow states may have good potential to be observed in future LHCb experiments.
