SU(3)-flavor breaking as a structural probe of hidden-charm-strange 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 to test whether SU(3)-flavor breaking acts as a universal mass shift or as a stru…
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 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 via QCD sum rules
Bing-Dong Wan, Yan Zhang, Jun-Hao Zhang +1
We investigate the 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…
