Predicting charmed-strange molecular tetraquarks with and -doublet charmed or anticharmed meson
Fu-Lai Wang, Si-Qiang Luo, Xiang Liu
In this work, we first present a systematic investigation of the -type charmed-strange molecular tetraquark candidates composed of a meson and a -d…
Systematic exploration of triply heavy tetraquarks: spectroscopic and decay characteristics
Hong-Tao An, Yu-Shuai Li, Si-Qiang Luo
While hidden, singly, doubly, and fully heavy tetraquark states have been experimentally observed, triply heavy tetraquark states remain experimentally unconfirmed. We systematical…
Investigating topped hadrons to probe the boundaries of the potential model
Si-Qiang Luo, Qi Huang, Xiang Liu
Inspired by the recent discovery of a pseudoscalar enhancement structure near the threshold reported by the CMS and ATLAS Collaborations, this work investigates the mass…
Assessing the validity of the Born-Oppenheimer approximation in potential models for doubly heavy hadrons
Zi-Long Man, Hao Zhou, Si-Qiang Luo +1
The Born-Oppenheimer approximation is widely used to investigate the properties of hydrogen-like systems and doubly heavy hadrons. However, the extent to which this approximation c…
Unquenched Charmonium and Beyond
Zi-Yue Bai, Dian-Yong Chen, Qi-Huang +3
The year 2024 marked the 50th anniversary of the discovery of the particle, which unveiled the charm quark and the charmonium spectrum, instigating the "November Revolution"…
Is the - mixing strong for the charmonia and ?
Zi-Long Man, Si-Qiang Luo, Xiang Liu
In this work, we revisit the - mixing scheme for the charmonia and . We introduce a coupled-channel mechanism-distinct from the tensor-force contributi…
