AI总结:

本文研究了$K^*(1680)$在强衰变中的性质,发现其衰变模式无法用常规$q\bar{q}$模型解释,提出了$q\bar{q}$-杂化混合机制,并为未来实验提供指导。

摘要:

我们对$K^*(1680)$状态在强衰变到两体最终态中的性质进行了研究,基于流管模型和夸克对创造模型。由于在奇魅领域中电荷共轭奇偶性不被保持,常规的$J^{P(C)}=1^{-(-)}$的$q\bar{q}$状态可以与最低的杂化状态$J^{P(C)}=1^{-(+)}$混合。我们对$K^*(1680)$的两体强衰变模式的分析表明,$K^*(1680)$的衰变模式无法用常规的$q\bar{q}$场景来解释。同时,强烈证据表明在奇魅领域中存在$q\bar{q}$-杂化混合机制。这种混合的现象学后果也被讨论。我们的研究可以为未来在BESIII、LHCb和Belle-II实验中寻找杂化多重态提供指导。

英文摘要:

We presents an investigation of the $K^*(1680)$ state in its strong decays into two-body finial states within the flux-tube model and quark pair creation model. Since the charge conjugation parity is not conserved in the strange sector, the conventional $q\bar{q}$ states of $J^{P(C)}=1^{-(-)}$ can mix with the lowest hybrid states with $J^{P(C)}=1^{-(+)}$. Our analysis of the $K^*(1680)$ two-body strong decays indicates that the decay pattern of $K^*(1680)$ cannot be explained by the conventional $q\bar{q}$ scenario. Meanwhile, strong evidence shows the $q\bar{q}$-hybrid mixing mechanism in the strange sector. The phenomenological consequences of such a mixing are also discussed. Our study can provide a guidance for the future search for hybrid multiplets in experiment at BESIII, LHCb, and Belle-II.
