摘要：

Stimulated by the state Y(4626) recently reported by the Belle Collaboration, we utilize a multiquark color flux-tube model with a multibody confinement potential and one-gluon-exchange interaction to make an exhaustive investigation on the diquark-antidiquark state [cs] [(c) over bar (s) over bar]. Numerical results indicate that the spatial configuration of the states [cs][(c) over bar (s) over bar] like a dumbbell, the larger the orbital excitation L, the farther the distance between the diquark [cs] and the antidiquark [(c) over bar (s) over bar], the more clearer the shape. The mixing of the color configurations [[cs]((3) over barc )[(c) over bar (s) over bar](3c)](1) and [[cs](6c) [(c) over bar (s) over bar]((6) over bar)(c)](1), in the ground states is strong, while the color configuration [[cs]((3) over barc )[(c) over bar (s) over bar](3c)](1) is absolutely predominant in the excited states. The states Y(4626), Y(4630), and Y(4660) can be uniformly described as the P-wave tetraquark state [cs][(c) over bar (s) over bar] with 1(--). The states Y(4626) and Y(4630) can be described as the same state consisting of a scalar [cs] and a scalar [(c) over bar (s) over bar], while the state Y(4660) is made of a scalar [cs] ([(c) over bar (s) over bar]) and an axial-vector [(c) over bar (s) over bar] (c. s]) Their hidden-bottom partner is predicted in the model calculation. The states X(4140), X(4274), X(4350), X(4500), and X(4700) are also discussed.
