${{\boldsymbol \Sigma}{(2250)}}$ $I(J^P)$ = $1(?^{?})$
Results from partial-wave analyses are too weak to warrant separating them from the production and cross-section experiments.
LASINSKI 1971 in ${{\overline{\mathit K}}}{{\mathit N}}$ using a Pomeron + resonances model, and
DEBELLEFON 1976 ,
DEBELLEFON 1977 , and
DEBELLEFON 1978 in energy-dependent partial-wave analyses of ${{\overline{\mathit K}}}$ ${{\mathit N}}$ $\rightarrow$ ${{\mathit \Lambda}}{{\mathit \pi}}$ , ${{\mathit \Sigma}}{{\mathit \pi}}$ , and ${{\mathit N}}{{\overline{\mathit K}}}$ , respectively, suggest two resonances around this mass.
