Understanding the low-lying structures from a coupled-channel perspective
Ying Zhang, Qing-Fu Song, Qi-Fang Lü +2
We perform a systematic analysis of the low-lying structures in a coupled-channel approach. The couplings between meson-baryon channels, , ,…
Exploring bottom-charmed molecular tetraquarks with the complex scaling method
Qing-Fu Song, Wei Liang, Qi-Fang Lü +1
In this work, we adopt the one-boson exchange model to analyze the interactions from a coupled-channel perspective. For the $DB^{*}…
An analysis on doubly bottom molecular tetraquarks composed of and doublets
Jun-Chao Su, Qing-Fu Song, Qi-Fang Lü +1
In this work, we investigate the doubly bottom and systems by adopting the one-boson-exchange model, where and represent…
Strong decays of wave doubly charmed and bottom baryons
Ya-Li Shu, Qing-Fu Song, Qi-Fang Lü
In this work, we investigate the strong decays for wave excited states of doubly charmed and bottom baryons in the constituent quark model. Our results indicate that some m…
Predicting hidden bottom molecular tetraquarks with a complex scaling method
Qing-Fu Song, Qi-Fang Lü, Dian-Yong Chen +1
In present work, we perform a coupled-channel analysis of systems with the one-boson-exchange potentials. We first study the $I(J^{PC})=1(1^{+-})…
Canonical interpretation of the newly observed structure
Tian-Ge Li, Sheng-Chao Zhang, Guan-Ying Wang +1
Inspired by the newly observed by the BESIII Collaboration, we study the strong decay behaviors of excited axialvector strange mesons within the quark pair creation model…
