论文摘要
我们采用手性夸克 - 苏利顿模型和重型夸克对称性来描述魅力和美容重子的光谱。可以根据光线部门的SU（3）表示重型重子。我们认为最近发现$ξ_b$状态可以解释为负奇偶校验激发的反三重或六重奏，而$σ_b$状态为负奇偶校验。讨论了此类分配对衰减模式的后果，并给出了未衡量的六重奏成员的质量的预测。
We employ the chiral quark-soliton model and the heavy quark symmetry to describe spectra of charm and beauty baryons. Heavy baryons can be classified according to the SU(3) representations of the light sector. We argue that recently discovered $Ξ_b$ states can be interpreted as negative parity excited anti-triplets or sextets, and the $Σ_b$ states as negative parity sextets. Consequences of such assignments for the decay patterns are discussed and also predictions of masses of the yet unmeasured sextet members are given.
