Systematic study of exotic tetraquark spectroscopy
Kai Xu, Zheng Zhao, Nattapat Tagsinsit +4
The masses of exotic quantum-number compact tetraquark states are calculated in a constituent quark model, where a Cornell-like potential is employed as the central potent…

Kai Xu, Attaphon Kaewsnod, Zheng Zhao +2
We investigate the helicity amplitudes of the and resonances in the electromagnetic transition process , where the and are assu…
Study of P wave charmoniumlike and bottomoniumlike tetraquark spectroscopy
Zheng Zhao, Attaphon Kaewsnod, Kai Xu +4
The masses of P-wave charmonium-like and bottomonium-like tetraquark states are calculated in a constituent quark model (CQM) where the Cornell-like potential and Breit-Fe…
Determining the Meson Cloud Contribution of Nucleon Electromagnetic Form Factor Using Dispersion Relation
Ek-ong Atthaphan, Attaphon Kaewsnod, Kai Xu +4
We explore the meson cloud contribution to nucleon electromagnetic form factors in dispersion relation approach. In our calculations, experimental data on transition amplitudes for…
states in the mixture of molecular and pentaquark pictures
Kai Xu, Kanokphon Phumphan, Wiriya Ruangyoo +3
We systematically study hidden charm pentaquark states in the constituent quark model with a general Hamiltonian for multiquark systems, considering the coupling between the $Σ_c^{…
Mass spectrum of heavy quarkonium
Zheng Zhao, Kai Xu, Ayut Limphirat +7
We calculate the masses and leptonic decay widths of the bottomonium and charmonium states in a constituent quark model where the Cornell-like potential and spi…
