Understanding the nature of in a coupled-channel approach
Qi-Fang Lü, Hideko Nagahiro, Atsushi Hosaka
We perform a systematic analysis of the mass and strong decays of the resonance in a coupled-channel approach of a bare three-quark state and a composite meson-baryon sta…
Canonical interpretation of the resonance
Zhuo Gao, Guan-Ying Wang, Qi-Fang Lü +2
The resonance observed by LHCb Collaboration is a strong candidate of the state according to its spin parity and strong decay mode. However, the…
Magic mixing angles for doubly heavy baryons
Takayuki Matsuki, Dian-Yong Chen, Xiang Liu +1
We study the so-called magic mixing angles for doubly heavy baryons. Defining that a magic mixing angle rotates states with definite to make them heavy-quark symme…
Possible Assignment of Excited Light Vector Mesons
Jie-Cheng Feng, Xian-Wei Kang, Qi-Fang Lü +1
We reanalyze the problems in the assignment of 3 and 4 light mesons, which have not yet been well established with the quark model. Regge trajectories and…
String point of view for heavy-light mesons
Yubing Dong, Qi-Fang Lü, Takayuki Matsuki
An approximate rotational symmetry of a heavy-light meson is viewed from a string picture. Using a simple string configuration, we derive a formula, , whose coeffici…
Approximate degeneracy of heavy-light mesons with the same
Takayuki Matsuki, Qi-Fang Lü, Yubing Dong +1
Careful observation of the experimental spectra of heavy-light mesons tells us that heavy-light mesons with the same angular momentum are almost degenerate. The estimate is giv…
