Light tetraquark states with $J^{P C} = 1^{--}$ from QCD sum rules

Yi-Wei Jiang, Hua-Xing Chen, Er-Liang Cui +3

We perform a systematic QCD sum rule study of light tetraquark states with $J^{P C} = 1^{--}$ in the diquark--antidiquark picture. A complete set of local interpolating currents is co…

A hybrid nonet with $J^{P C} = 1^{-+}$ or a tetraquark 81-plet

Niu Su, Er-Liang Cui, Yi-Wei Jiang +1

Confirming the existence of hybrid states remains challenging due to their experimental indistinguishability from tightly bound tetraquarks and loosely bound molecules. To address…

Strong decays of the $ϕ (2170)$ as a fully-strange tetraquark state

Yi-Wei Jiang, Wei-Han Tan, Hua-Xing Chen +1

We study strong decays of the $ϕ (2170)$ , along with its possible partner $X (2436)$ , as two fully-strange tetraquark states of $J^{P C} = 1^{--}$ . We consider seven decay channels: $…
