Description

In the framework of the color-magnetic interaction, we systematically investigate the mass splittings of the QQ anti Q anti q tetraquark states and estimate their rough masses in this work. These systems include the explicitly exotic states cc anti b anti q and bb anti c anti q and the hidden exotic states cc anti c anti q, cb anti b anti q, bc anti c anti q, and bb anti b anti 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. (orig.)
