On the nature of X(3960)
Yu Chen, Hao Chen, Ce Meng +2
A near-threshold enhancement in the system, dubbed as , is observed by the LHCb collaboration recently. A combined analysis on ,…
Identifying Hadronic Molecular States with a Neural Network
Chang Chen, Hao Chen, Wen-Qi Niu +1
Neural networks are trained to judge whether or not an exotic state is a hadronic molecule of a given channel according its line-shapes. This method performs well in both trainings…
X_1(2900) as a D_1 K molecule
Hao Chen, Hong-Rong Qi, Han-Qing Zheng
The analyses of the LHCb data on X(2900) in the D^- K^+ spectrum are performed. Both dynamically generated and explicitly introduced X_1(2900) are considered. The results show that…
Some remarks on
Qin-Fang Cao, Hao Chen, Hong-Rong Qi +1
The analysis of the LHCb data on found in the di-$\jpsi$ system is performed using a momentum-dependent Flatté-like parameterization. The use of the pole counting rule an…
A Review on Partial-wave Dynamics with Chiral Effective Field Theory and Dispersion Relation
De-Liang Yao, Ling-Yun Dai, Han-Qing Zheng +1
The description of strong interaction physics of low-lying resonances is out of the valid range of perturbative QCD. Chiral effective field theories have been developed to tackle t…
How does the state emerge from a naive matrix fit?
Yao Ma, Wen-Qi Niu, Yu-Fei Wang +1
We give a pedagogical analysis on matrix models describing the scattering amplitude, in channel at low energies. We show how the correct use of analyticity in the…
