Fully-light vector tetraquark states with explicit P-wave via QCD sum rules*

Abstract

Abstract In this study, we apply the QCD sum rules to investigate the vector fully-light tetraquark states with an explicit P-wave between the diquark and antidiquark pairs. We observed that the (or ) type current with fully-strange quarks couples potentially to a tetraquark state with a mass , which supports assigning as the diquark-antidiquark type tetraquark state with . The and vector tetraquark states with the structure (or ) are consistent with and , respectively, which lie in the region from to . The central values of the masses of the fully-strange vector tetraquark states with an explicit P-wave are approximately (or ). Predictions for other fully-light vector tetraquark states with and without hidden-strange are also presented.
