${{\boldsymbol \Lambda}{(2000)}}$

$I(J^P)$ = $0(1/2^{-})$ 
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 .
