Systematic study of exotic $1^{-+}$ tetraquark spectroscopy

Kai Xu, Zheng Zhao, Nattapat Tagsinsit +4

The masses of exotic quantum-number $1^{-+}$ compact tetraquark states are calculated in a constituent quark model, where a Cornell-like potential is employed as the central potent…

Helicity amplitudes of $N (1520)$ and $N (1535)$ including pentaquark components

Kai Xu, Attaphon Kaewsnod, Zheng Zhao +2

We investigate the helicity amplitudes of the $N (1520)$ and $N (1535)$ resonances in the electromagnetic transition process $γ^{*} p \to N^{*}$ , where the $N (1520)$ and $N (1535)$ are assu…

Study of $1^{--}$ P wave charmoniumlike and bottomoniumlike tetraquark spectroscopy

Zheng Zhao, Attaphon Kaewsnod, Kai Xu +4

The masses of $1^{--}$ 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…
