Hidden charm pentaquarks and the nature of $P_{c}$ states observed at LHCb

Zhi-Biao Liang, Jun-Jie Liu, Mu-Yang Chen +2

We carry out a unified study of the low-lying $1 S$ -wave compact states and hadronic molecules composed of hidden charm pentaquarks $q q q c c ˉ$ ( $q = u, d$ ) within a semirelativistic…

Singly heavy tetraquarks

Jun-Jie Liu, Zhi-Biao Liang, Feng-Xiao Liu +3

In this work, we carry out a systematic study of the spectra of the $1 S$ -wave states for the whole singly-heavy tetraquark systems within a semi-relativistic hybrid quark potential…

Unified study of nucleon and $Δ$ baryon spectra and their strong decays with chiral dynamics

Hui-Hua Zhong, Ming-Sheng Liu, Ru-Hui Ni +3

In this work we systematically study both the mass spectra and strong decays of the nucleon and $Δ$ resonances up to the $N = 2$ shell within a unified quark model framework with chi…

Running Coupling and Running Quark Mass Effects on the Elastic Form Factors of Nucleons

Bao-Yi Yang, Hui-Hua Zhong, Muyang Chen

We study the elastic electric and magnetic form factors of the proton, neutron and the charged roper resonance ( $G_{E}^{p}$ , $G_{M}^{p}$ , $G_{E}^{n}$ , $G_{M}^{n}$ , $G_{E}^{R}$ and $G_{M}^{R}$ ) systematica…
