Within the framework of a color flux-tube model with a four-body confinement potential,the tetraquark states [cq][(c)(q)] (q =u or d) with IJPC =01--are systematically investigated.The numerical results indicate that states Y(4008),Y(4140),Y(4260),and Y(4360) can be uniformly described as tetraquark states [cq][(c)(q)] with n2S+1LJ of 1ip1,15p1,25p1 and 15F1,respectively,in the color flux-tube model.They are compact threedimensional spatial configurations similar to a rugby ball,higher orbital angular momentum L,more prolate.The four-body confinement interaction based on a c0l0r flux-tube picture should be responsible for the formation of those compact tetraquark states.
