# ${{\boldsymbol \Xi}{(1530)}}$ $I(J^P)$ = $1/2(3/2^{+})$

This is the only ${{\mathit \Xi}}$ resonance whose properties are all reasonably well known. Assuming that the ${{\mathit \Lambda}_{{c}}^{+}}$ has $\mathit J{}^{P} = 1/2{}^{+}$, AUBERT 2008AK, in a study of ${{\mathit \Lambda}_{{c}}^{+}}$ $\rightarrow$ ${{\mathit \Xi}^{-}}{{\mathit \pi}^{+}}{{\mathit K}^{+}}$ , finds conclusively that the spin of the ${{\mathit \Xi}{(1530)}^{0}}$ is 3/2. In conjunction with SCHLEIN 1963B and BUTTON-SHAFER 1966 , this proves also that the parity is $\text{+}$. We use only those determinations of the mass and width that are accompanied by some discussion of systematics and resolution.
