关于重子奇异性的一种可能性
On a possibility of baryonic exotica
摘要：
基于手征对称性的模型预测了质量相对较低的五夸克。我们简要地回顾了奇异光的理论和实验研究现状。接下来，将展示如何将手征模型推广到具有一个重夸克的重子，并展示在这种情况下也会出现奇异夸克。最后，我们解释最近发现的LHCb合作五个$Ω^*_c$共振的规则和异国情调的激发的基态$Ω_c$。
英文摘要：
Models based on chiral symmetry predict pentaquarks that have relatively low masses. We briefly review both theoretical and experimental status of exotica in the light sector. Next, shall show how to extend chiral models to baryons with one heavy quark and show that one expects exotica also in this case. Finally, we interpret recently discovered by the LHCb collaboration five $Ω^*_c$ resonances in terms of regular and exotic excitations of the ground state $Ω_c$.
