The excited baryon spectrum from a unified quark model
Yan-Ke Chen, Liang-Zhen Wen, Wei-Lin Wu +2
A common approach to studying the multiquark states is to solve the few-body Schrödinger equation within a quark potential model. The multiquark states may contain quarks with seve…
Emergence of the exotic bottomoniumlike state and support from Belle and Belle II data
Jun-Zhang Wang, Yu-Bo Li, Jian-Bo Cheng +4
Near-threshold exotic hadrons are usually associated with -wave hadron-hadron dynamics, while higher partial waves are expected to be strongly suppressed by the centrifugal barr…
Three-body molecular states composed of and two nucleons
Si-Yi Chen, Fei-Yu Chen, Xu-Liang Chen +3
We study the three-body systems and within a hadronic molecular framework by combining a realistic nucleon-nucleon interaction with a potential constrain…
DeepQuark: A Deep-Neural-Network Approach to Multiquark Bound States
Wei-Lin Wu, Lu Meng, Shi-Lin Zhu
For the first time, we implement the deep-neural-network-based variational Monte Carlo approach for the multiquark bound states, whose complexity surpasses that of electron or nucl…
Existence of the and three-body molecular states
Yan-Ke Chen, Lu Meng, Jun-Zhang Wang +1
We investigate the existence of the three-body molecular state composed of within the one-boson-exchange (OBE) model. A major challenge is that while the pseudoscal…
Tetraquark states in the quark model
Wei-Lin Wu, Yan-Ke Chen, Yao Ma +2
We perform systematical investigations of heavy flavor tetraquark systems, including fully heavy (), doubly heavy (), and…
