$|\Delta I|=3/2$ 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 $|\Delta I|=3/2$ amplitudes in covariant baryon chiral perturbation theory with the extended…
