$Ω(2012)$通过风味的镜子SU（3）
$Ω(2012)$ through the looking glass of flavour SU(3)
摘要：
我们对最近发现的$Ω(2012)$超子进行了味$SU(3)$分析。我们发现，如果$\le 70$的三体衰变分支不是太大，那么具有$J^P=3/2^-$量子数的著名的（四星）$Δ(1700)$共振是$Ω(2012)$的十重态伙伴的一个很好的候选者.这意味着$Ω(2012)$的量子数是$I(J^P)=0(3/2^-)$。对仍然缺少的$Σ$和$Ξ$十重态成员的性质进行了预测。我们还讨论了$Ω(2012)$的${ \overline{ K} Ξ(1530)}$分子图像的影响。关键的实验测试，以区分各种图片的$Ω(2012)$的建议。
英文摘要：
We perform the flavour $SU(3)$ analysis of the recently discovered $Ω(2012)$ hyperon. We find that well known (four star) $Δ(1700)$ resonance with quantum numbers of $J^P=3/2^-$ is a good candidate for the decuplet partner of $Ω(2012)$ if the branching for the three-body decays of the latter is not too large $\le 70$\%. That implies that the quantum numbers of $Ω(2012)$ are $I(J^P)=0(3/2^-)$. The predictions for the properties of still missing $Σ$ and $Ξ$ decuplet members are made. We also discuss the implications of the ${ \overline{ K} Ξ(1530)}$ molecular picture of $Ω(2012)$. Crucial experimental tests to distinguish various pictures of $Ω(2012)$ are suggested.
