作为重五夸克态的激发态$Ω$

Excited $Ω$'s as heavy pentaquarks

Hyun-Chul Kim

摘要:

我们简要地总结了最近的工作,对识别的激发$Ω_c$的LHCb合作发现。在π平均场方法的框架内,下列情况是最有利的:三个激发态$Ω_c$属于激发态重子六重态,其中两个衰变宽度较小的粒子可以被识别为反十五峰,这是最低位的表示之一。这意味着这两个$Ω_c$,即$Ω(3050)$和$Ω(3119)$很可能是奇异的重五夸克重子.

英文摘要:

We briefly summarize recent works on the identification of the excited $Ω_c$'s found by the LHCb Collaboration. Within the framework of a pion mean-field approach, the following scenario is the most favorable: While three of the excited $Ω_c$'s belong to the excited baryon sextet, two of them with the smaller decay widths can be identified as the members of the anti-decapentaplet which is one of the lowest-lying representations. It implies that these two $Ω_c$'s, i.e. $Ω(3050)$ and $Ω(3119)$ are most probably the exotic heavy pentaquark baryons.
