Decay Rates ofY0*(1520)and its SU(3) Classification

Available data for the reaction $K^{-}+p\to {Y_1}^{*}\mathrm{}\left(1765\right)\mathrm{}\to {Y_0}^{*}\mathrm{}\left(1520\right)+\pi$ are studied to obtain rates for ${Y_0}^{*}\mathrm{}\left(1520\right)\mathrm{}$ decaying into $\overline{K}N$, $\Sigma \pi$, and $\Lambda \pi \pi$ channels. The weighted average of all determinations of the ratio of squares of the reduced matrix elements for $\Sigma \pi$ and $N\overline{K}$ modes is found to have a value incompatible with the assumption that ${Y_0}^{*}\mathrm{}\left(1520\right)\mathrm{}$ is a pure SU(3) singlet. Therefore, either ${Y_0}^{*}\mathrm{}\left(1520\right)\mathrm{}$ is likely to be mixed with a ${\frac{3}{2}}^{-}$ octet or unbroken SU(3) branching ratio predictions are unreliable or difficult to compare with experiment.
