Abstract.

In the framework of the color-magnetic interaction, we systematically investigate the mass splittings of the \(QQ\bar{Q}\bar{q}\) tetraquark states and estimate their rough masses in this work. These systems include the explicitly exotic states \(cc\bar{b}\bar{q}\) and \(bb\bar{c}\bar{q}\) and the hidden exotic states \(cc\bar{c}\bar{q}\), \(cb\bar{b}\bar{q}\), \(bc\bar{c}\bar{q}\), and \(bb\bar{b}\bar{q}\). If a state around the estimated mass region can be observed, its nature as a genuine tetraquark is favored. The strong decay patterns shown here will be helpful to the experimental search for these exotic states.
