non-leptonic hyperon decays in covariant baryon chiral perturbation theory
Jie Xu, Jun-Xu Lu, Rui-Xiang Shi +1
Inspired by the recent BESIII measurements of non-leptonic hyperon decays, we reexamine their amplitudes in covariant baryon chiral perturbation theory with the extended…
Probing the three-body force in hadronic systems with specific charge parity
Ya-Wen Pan, Ming-Zhu Liu, Li-Sheng Geng
Three-body forces, a type of non-perturbative strong interaction, are widely studied in nuclear physics. However, whether their inclusion is necessary in nuclear systems remains a…
Strangeness is the key: from to
Li-Sheng Geng, Ming-Zhu liu, Jia-Ming Xie
The kaon, the lightest hadron containing a strangeness quark, is very peculiar. It is a Nambu-Goldstone boson, but significantly heavier than the pion. As a result, its interaction…
femtoscopy and the nature of
Yi-Bo Shen, Zhi-Wei Liu, Ming-Zhu Liu +4
Over the past two decades, numerous exotic hadron states have been discovered, yet their underlying nature remains unclear. It is widely acknowledged that understanding hadron-hadr…
Femtoscopy can tell whether and are resonances or virtual states
Zhi-Wei Liu, Jun-Xu Lu, Ming-Zhu Liu +1
There have been extended and heated discussions on the nature of the two exotic states, and , particularly whether they are near-threshold resonances, vir…
Charmonium-nucleon femtoscopic correlation function
Zhi-Wei Liu, Duo-Lun Ge, Jun-Xu Lu +2
This study investigates the femtoscopic correlation functions of charmonium-nucleon pairs, utilizing the lattice QCD phase shifts provided by the HAL QCD Collaboration. A ``model-i…
