Within the framework of a color flux-tube model with a four-body confinement potential, the tetraquark states [cq][Oc]] (q =u or d) with IJPc = 01-- are systematically investigated. The numerical results indicate th...

We take the viewpoint that X(1576) is the tetraquark state which consists of a scalar diquark and an antiscalar-diquark in relative P-wave, and calculate its mass in the framework of the QCD sum rule approach. The n...
