$∣Δ I ∣ = 3/2$ 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 $∣Δ I ∣ = 3/2$ amplitudes in covariant baryon chiral perturbation theory with the extended…

Strangeness is the key: from $K ˉ N$ to $D ˉ_{s} D K$

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…
