${{\mathit \Sigma}{(1915)}}$

$I(J^P)$ = $1(5/2^{+})$ 
Discovered by COOL 1966. For results published before 1974 (they are now obsolete), see our 1982 edition Physics Letters 111B 1 (1982). This entry only includes results from partial-wave analyses. Parameters of peaks seen in cross sections and invariant-mass distributions in this region used to be listed in in a separate entry immediately following. They may be found in our 1986 edition Physics Letters 170B 1 (1986).
