摘要:

最近发现的$d^*(2380)$六夸克态被认为是扩展的SU(3)反十重态中最轻的一个。在反十重态中寻找$d^*(2380)$的其他更重和奇怪的伙伴是一项具有挑战性的任务。评估最合适的方法需要对十重态的基本性质(如质量、宽度和衰变分支)有一定的了解。在本文中,我们提供了所有十重态的这些关键属性的估计,从$d^*(2380)$获得的信息和见解推断。这些预测构成了未来发现实验设计的基础。

英文摘要:

The recently discovered $d^*(2380)$ hexaquark is expected to be the lightest member of an extended SU(3) antidecuplet of hexaquark states. The experimental search for the other heavier and strange partners of the $d^*(2380)$ in the antidecuplet is a challenging task. Evaluating the most appropriate methodologies necessitates some understanding of the underlying properties of the decuplet states such as mass, width and decay branches. In this paper we provide estimates of these key properties for all decuplet states, extrapolating from information and insights garnered for the $d^*(2380)$. The predictions form a basis for the design of future discovery experiments.
