我们通过在固定中心近似下求解Faddeev方程来研究三体系统，其中轻粒子与形成团簇的()的重束缚态相互作用。根据实验中受观测和态约束的非常吸引的和子系统，我们在和系统中发现了两个包含隐底分量的深束缚态，质量分别为和。并预测了上述体系的两个质量较高的对应状态。此外，利用重夸克扇区中的和通过隐藏规范对称性的约束两体振幅，我们还发现了两个三体束缚态。
We study the three-body systems ofby solving the Faddeev equations in the fixed-center approximation, where the light particleinteracts with the heavy bound states of() forming the clusters. In terms of the very attractiveandsubsystems, which are constrained by the observedandstates in experiment, we find two deep bound states, containing the hidden-bottom components, with massesandin theandsystems, respectively. The two corresponding states with higher masses of the above systems are also predicted. In addition, using the constrained two-body amplitudes ofandvia the hidden gauge symmetry in the heavy-quark sector, we also find two three-bodyandbound states.
