On Compositeness of and its decay to
Yu-Hui Zhou, Xiu-Li Gao, Bin Wu +2
We demonstrate that the can be described as a bound-state pole arising from the coupling between a discrete state and the continuum state…
Comparing relativistic and non-relativistic quark pair creation models
Xiu-Li Gao, Yu-Hui Zhou, Bin Wu +1
We investigate the strong decay properties of light unflavored and strange mesons within a relativistic quark-pair-creation (QPC) framework, and compare the results with those obta…
Understanding the 1P- and 2S-wave nucleon resonances within the extended Lee-Friedrichs Model
Yu-Hui Zhou, Hui-Hua Zhong, Zhi-Yong Zhou +1
We present a unified desciption of the low-lying - and -wave nucleon resonance within the framework of an extended Lee-Friedrichs scheme. By incorporating the coupled-chann…
Updated analysis of charmonium states in a relativized quark potential model
Xiu-Li Gao, Jun-Xi Cui, Yu-Hui Zhou +1
Motivated by recent experimental observations of charmonium(-like) states, we investigate their interpretation as conventional charmonium states within the framework of relativized…
