Hidden-charm and -bottom tetraquark states with $J^{PC}=1^{-+}$ via QCD sum rules

Bing-Dong Wan, Yan Zhang, Jun-Hao Zhang +1

We investigate the $1^{-+}$ hidden-charm and hidden-bottom tetraquark states within the framework of QCD sum rules. The mass spectra are computed by including condensates up to dim…
