${{\mathit \Lambda}{(2000)}}$ $I(J^P)$ = $0(1/2^{-})$

BARBARO-GALTIERI 1970 (in ${{\mathit \Sigma}}{{\mathit \pi}}$) and BRANDSTETTER 1972 (in ${{\mathit \Lambda}}{{\mathit \omega}}$) proposed a state at about this mass. Those analyses are considered to be obsolete, see NAKKASYAN 1975 and PDG 2018.
