Review of the low-lying excited baryons ${\Sigma }^{\ast }(1/2^{-})$

En Wang, Li-Sheng Geng, Jia-Jun Wu +2

Strong empirical and phenomenological indications exist for large sea-quark admixtures in the low-lying excited baryons. Investigating the low-lying excited baryon ${\Sigma }^{\ast }(1/2^{-})$ is…
