${{\boldsymbol \Lambda}{(2000)}}$ $I(J^P)$ = $0(?^{?})$

ZHANG 2013A claims a $\mathit J{}^{P} = 1/2{}^{-}$ state. We list here all the ambiguous resonance possibilities with a mass around 2 GeV. The proposed quantum numbers are ${\mathit D}_{\mathrm 3}$ (BARBARO-GALTIERI 1970 in ${{\mathit \Sigma}}{{\mathit \pi}}$ ), ${\mathit D}_{\mathrm 3}+{\mathit F}_{\mathrm 5}$, ${\mathit P}_{\mathrm 3}+{\mathit D}_{\mathrm 5}$, or ${\mathit P}_{\mathrm 1}+{\mathit D}_{\mathrm 3}$ (BRANDSTETTER 1972 in ${{\mathit \Lambda}}{{\mathit \omega}}$ ), and ${\mathit S}_{\mathrm 1}$ (CAMERON 1978B in ${{\mathit N}}{{\overline{\mathit K}}^{*}}$ ). The first two of the above analyses should now be considered obsolete. See also NAKKASYAN 1975 .
