Searching for fully-heavy tetraquark states in QCD moment sum rules
Wei Chen, Qi-Nan Wang, Zi-Yan Yang +4
In this talk, we briefly report the investigations of the mass spectra for the , and tetraquark states by using th…
Light double-gluon hybrid states from QCD sum rules
Niu Su, Hua-Xing Chen, Wei Chen +1
We study the double-gluon hybrid states with the quark-gluon contents () and . We construct twelve double-gluon hybrid currents with various quant…
Decay behaviors of the fully-bottom and fully-charm tetraquark states
Hua-Xing Chen, Yi-Xin Yan, Wei Chen
We study the decay behaviors of the fully-bottom tetraquark states within the diquark-antidiquark picture, and calculate their relative branching ratios through the Fierz rearrange…
Highly excited and exotic fully-strange tetraquark states
Rui-Rui Dong, Niu Su, Hua-Xing Chen
Some hadrons have the exotic quantum numbers that the traditional mesons and baryons can not reach, such as , e…
Newly observed as the scaling point of constructing the scalar meson spectroscopy
Dan Guo, Wei Chen, Hua-Xing Chen +2
Stimulated by the newly observed by the BESIII Collaboration, we find a perfect Regge trajectory composed of the , , and , which leads u…
Identifying the as the -wave bottom baryon of
Hui-Min Yang, Hua-Xing Chen, Er-Liang Cui +1
We study the using the methods of QCD sum rules and light-cone sum rules within the framework of heavy quark effective theory. Our results suggest that the …
