Practical parametrization of two-pole structure
J. X. Cui, Zhi-Yong Zhou, Zhiguang Xiao
We suggest that the extended Lee-Friedrichs model could be directly used as a practical parametrization method for the experimental analysis of resonance structures. This parametri…
On the generalized Friedrichs-Lee model with multiple discrete and continuous states
Zhiguang Xiao, Zhi-Yong Zhou
In this study, we present several improvements of the non-relativistic Friedrichs-Lee model with multiple discrete and continuous states and still retain its solvability. Our findi…
Reconciling experimental and lattice data of in a - coupled-channel analysis
Lin-Wan Yan, Zhi-Hui Guo, Feng-Kun Guo +2
We study the and coupled-channel system within a covariant framework. The and invariant-mass distributions measured at 4.23~GeV and 4.26~GeV…
A new look at and
Zhi-Yong Zhou, Chun-Yong Li, Zhiguang Xiao
By simultaneously analyzing the cross section data of in a coupled-channel scheme with unitarity, we found that, in co…
Reply to "comment on `Scrutinizing scattering in light of recent lattice phase shifts'"
Xiu-Li Gao, Zhi-Hui Guo, Zhiguang Xiao +1
We reply to the comment [arxiv:2202.08809] by E. van Beveren and G. Rupp on our recent work [arxiv:2202.03124], by further clarifying the difference between the two approaches. We…
Scrutinizing scattering in light of recent lattice phase shifts
Xiu-Li Gao, Zhi-Hui Guo, Zhiguang Xiao +1
In this paper, the partial wave scattering phase shifts determined by the lattice QCD approach are analyzed by using a novel dispersive solution of the S-matri…
