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…

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^{…

Holography and the KKLT Scenario

Severin Lüst, Cumrun Vafa, Max Wiesner +1

The KKLT scenario, one of the few ideas to realize dS vacua in string theory, consists of two steps: the first involves the construction of a supersymmetric AdS vacuum with a small…

A possible interpretation of baryon spectrum with pentaquark components

Kai Xu, Attaphon Kaewsnod, Zheng Zhao +3

The baryon spectrum is studied within the SU(3) flavor symmetry in a constituent quark model. We found that it is rather difficult to accommodate some negative-parity reson…

Group Theory Analysis of Resonances in Molecular Picture

Kanokphon Phumphan, Kai Xu, Wiriya Ruangyoo +3

Hidden-charm pentaquarks are analysed in Group Theory in the baryon-meson molecule picture within the framework of the constituent quark model. The investigation of strong decays o…
