${{\mathit \Sigma}{(1880)}}$ $I(J^P)$ = $1(1/2^{+})$

A ${\mathit P}_{\mathrm 11}$ resonance is suggested by several partial-wave analyses, but with wide variations in the mass and other parameters. We list here all claims which lie well above the ${\mathit P}_{\mathrm 11}{{\mathit \Sigma}{(1770)}}$.
