${{\boldsymbol \Xi}{(2030)}}$ $I(J^P)$ = $1/2({5\over~2}^{?})$
The evidence for this state has been much improved by
HEMINGWAY 1977 , who see an eight standard deviation enhancement in ${{\mathit \Sigma}}{{\overline{\mathit K}}}$ and a weaker coupling to ${{\mathit \Lambda}}{{\overline{\mathit K}}}$ .
ALITTI 1968 and
HEMINGWAY 1977 observe no signals in the ${{\mathit \Xi}}{{\mathit \pi}}{{\mathit \pi}}$ (or ${{\mathit \Xi}{(1530)}}{{\mathit \pi}}$ ) channel, in contrast to
DIBIANCA 1975 . The decay (${{\mathit \Lambda}}/{{\mathit \Sigma}}$) ${{\overline{\mathit K}}}{{\mathit \pi}}$ reported by
BARTSCH 1969 is also not confirmed by
HEMINGWAY 1977 . A moments analysis of the
HEMINGWAY 1977 data indicates at a level of three standard deviations that $\mathit J$ ${}\geq{}{}^{}5/2{}^{}$.
