SU(3)-flavor breaking as a structural probe of hidden-charm-strange $0^{--}$ tetraquarks in a color-octet basis

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

We study hidden-charm-strange tetraquark candidates with the exotic quantum number $J^{P C} = 0^{--}$ to test whether SU(3)-flavor breaking acts as a universal mass shift or as a stru…

Spectroscopy of hidden-heavy tetraquark states with $J^{P C} = 0^{--}$ in a color-octet configuration

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

Within the QCD sum-rule framework, we investigate hidden-heavy tetraquark channels with the exotic quantum number $J^{P C} = 0^{--}$ using four representative local color-octet--octet…

Light baryonium states with exotic quantum numbers

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

The existence of baryonium-bound or resonant states composed of a baryon and an antibaryon has long been postulated as a natural extension of conventional hadron spectroscopy. In t…

Spectrum of $J^{P C} = 0^{\pm\pm}$ Gluonic Hidden-Charm Tetraquark States

Bing-Dong Wan, Ming-Yang Yuan, Jun-Hao Zhang +1

We investigate gluonic hidden-charm tetraquark states composed of two valence quarks, two valence antiquarks and an explicit valence gluon. In the color configuration $[\bar{3}_c]_…

Hidden-charm and -bottom tetraquark states with $J^{P C} = 1^{-+}$ 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…
