${{\boldsymbol \Sigma}{(2030)}}$ $I(J^P)$ = $1(7/2^{+})$

Discovered by COOL 1966 and by WOHL 1966 . For most 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 around 2030 MeV may be found in our 1984 edition, Reviews of Modern Physics 56 S1 (1984).
