Studies of low energy process in covariant chiral perturbation theory
Xu Wang, Kai-Ge Kang, Zhiguang Xiao +1
This study presents a tree-level calculation of the scattering amplitude for the (with a hard photon) process within the framework of Chiral Perturbation Theory. Our ca…
A discussion on the anomalous threshold enhancement of -- couplings and peak
Ye Lu, Chang Chen, Guang-you Qin +1
The attractive interaction between and has to be strong enough to form the molecular resonant structure, i.e., . We argue that since decays predo…
Some remarks on compositeness of
Chang Chen, Ce Meng, Zhiguang Xiao +1
Recently LHCb experimental group find an exotic state from the process . A key question is if it is just a molecule or may have confined tetr…
Roy equation analyses of scatterings at unphysical pion masses
Xiong-Hui Cao, Qu-Zhi Li, Zhi-Hui Guo +1
An extended Roy equation including a bound state pole is used to study scatterings at unphysical large pion masses when becomes a bound state in one situation and stays as…
A possible subthreshold pole in channel from Roy-Steiner equation analyses
Xiong-Hui Cao, Qu-Zhi Li, Han-Qing Zheng
The hyperbolic version of Roy-Steiner equation describing low energy scatterings, with larger analyticity domain in the complex plane is solved. The numerical results on p…
On Lowest Lying Octet Baryons
Chang Chen, Wen-Qi Niu, Han-Qing Zheng
The recently proposed baryon is studied in a flavor scheme with matrix unitarization, by fitting to low energy cross section and phase shift data. It…
