Revisiting the as a hadronic molecule and its strong decays
Jun-Xu Lu, Chun-Hua Zeng, En Wang +2
Recently, the Belle collaboration measured the ratios of the branching fractions of the newly observed excited state. They did not observe significant signals for the $Ω(…
The interaction and resonances in photon-photon scattering
Junxu Lu, B. Moussallam
We revisit the information on the two lightest resonances and -wave scattering that can be extracted from photon-photon scattering experiments. For this purpose we co…
Meson-baryon scattering up to the next-to-next-to-leading order in covariant baryon chiral perturbation theory
Jun-Xu Lu, Li-Sheng Geng, Xiu-Lei Ren +1
We study the scattering of a pseudoscalar meson off one ground state octet baryon in covariant baryon chiral perturbation theory (BChPT) up to the next-to-next-to-leading order. Th…
The resonance as a dynamically generated state: the compositeness condition and the large evolution
Jun-Xu Lu, Hua-Xing Chen, Zhi-Hui Guo +3
Recent studies have shown that the well established resonance contains a large meson-baryon component, which can vary depending on the specific formalism. In this work,…
