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…
The and decays
Qi Wu, Jun-Zhang Wang, Shi-Lin Zhu
We study the and meson contribution to the radiative decays and . The is dominated by the $…
A comparison between the and systems
Kan Chen, Zi-Yang Lin, Shi-Lin Zhu
We construct the effective potentials of the and states based on the SU(3) symmetry and heavy quark symmetry. Then we perform the coupled-channel analys…
Double-charm and hidden-charm hexaquark states under the complex scaling method
Jian-Bo Cheng, Du-xin Zheng, Zi-Yang Lin +1
We investigate the double-charm and hidden-charm hexaquarks as molecules in the framework of the one-boson-exchange potential model. The multichannel coupling and wave mixing…
Ground state baryons in the flux-tube three-body confinement model using Diffusion Monte Carlo
Yao Ma, Lu Meng, Yan-Ke Chen +1
We make a systematical diffusion Monte Carlo (DMC) calculation for all ground state baryons in two confinement scenarios, the pairwise confinement and the three-body flux-tube conf…
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…
