Off-shell Chiral Dynamics in the Resonance and Femtoscopic Correlations
Jia-Ming Xie, Zhi-Wei Liu, Jun-Xu Lu +2
We present the first systematic investigation of the meson--baryon interaction within a fully off-shell covariant unitarized chiral effective field theory framework up to ne…
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…
Probing the di- interaction and the nature of with femtoscopic correlation functions
Zhi-Wei Liu, Jia-Ming Xie, Jun-Xu Lu +1
Recent re-analyses of the di- invariant mass spectra reveal a state near the di- threshold, referred to as the . Yet the nature of this near-threshold pole--whet…
Chiral Evolution and Femtoscopic Signatures of the Resonance
Jia-Ming Xie, Zhi-Wei Liu, Jun-Xu Lu +3
We present a comprehensive study of the axial-vector resonance within the unitarized chiral perturbation theory, focusing on its two-pole structure and manifestation in…
Two-pole structures in QCD -- a universal phenomenon governed by chiral dynamics
Jia-Ming Xie, Jun-Xu Lu, Li-Sheng Geng +1
We illustrate how the two-pole structures of the emerge from the underlying universal chiral dynamics that describe the coupled-channel interactions between octet baryons…
