#### ${{\boldsymbol \Xi}{(1620)}}$

$I(J^P)$ = $1/2(?^{?})$ J, P need confirmation.
What little evidence there is consists of weak signals in the ${{\mathit \Xi}}{{\mathit \pi}}$ channel. A number of other experiments (e.g., BORENSTEIN 1972 and HASSALL 1981 ) have looked for but not seen any effect.
