The two-body strong decays of the fully-charm tetraquark states

We study the hadronic coupling constants in the two-body strong decays of the fully-charm tetraquark states with the J PC = 0 + + , 1 + - , and 2 + + via the QCD sum rules based on rigorous quark-hadron duality. Then we obtain the hadronic coupling constants and partial decay widths therefore total...

Summary:We study the hadronic coupling constants in the two-body strong decays of the fully-charm tetraquark states with the J PC = 0 + + , 1 + - , and 2 + + via the QCD sum rules based on rigorous quark-hadron duality. Then we obtain the hadronic coupling constants and partial decay widths therefore total decay widths, which support assigning the X (6552) as the first radial excitation of the scalar tetraquark state. And other predictions can be used to diagnose exotic states in the future.
