On the nature of the lowest $1/2^-$ baryon nonet and decuplet

From recent study of properties of the lowest spin-parity $1/2^-$ baryons, $N^*(1535)$ and $Δ^*(1620)$, new pictures for the internal structure of the lowest $1/2^-$ baryon octet and decuplet are proposed. While the lowest $1/2^-$ baryon octet may have large diquark-diquark-antiquark component, the lowest $1/2^-$ baryon decuplet is proposed to have large vector-meson-baryon components. Evidence for the "missing" members of the new pictures is pointed out and suggestions are made for detecting these predicted states from forthcoming experiments.
