论文摘要
LHCB合作在2017年在CERN报告的两个狭窄的$ω^0_c $的一种可能解释是，它们是属于Chiral Quark-Soliton模型所预测的属于$ \ overline {\ boldsymbol {15}} $ Exotic Su（3）的pentaquarks。如果是这样，则必须存在许多其他异国情调的状态，因为该模型预测了三个不同的$ \ edline {\ boldsymbol {15}} $重型重男性的多重多重。我们表明，根据Soliton Spin $ J $，这些状态非常狭窄或非常宽。这解释了为什么他们可能逃脱了实验性观察。此外，我们表明，这些多重运动中最轻的成员在两个身体强腐烂的情况下是稳定的。
One possible interpretation of two narrow $Ω^0_c$ states reported by the LHCb Collaboration at CERN in 2017 is that they are pentaquarks belonging to a $\overline{\boldsymbol{15}}$ exotic SU(3) representation, as predicted by the Chiral Quark--Soliton Model. If so, there must exist a number of other exotic states since the model predicts three different $\overline{\boldsymbol{15}}$ multiplets of heavy baryons. We show, that depending on the soliton spin $J$, these states are either very narrow or very broad. This explains why they might have escaped experimental observation. Furthermore, we show that the lightest members of these multiplets are stable against two body strong decays.
