论文摘要
提出了一种新的状态分类方案，并应用于分析重baryons $ω_{q} $，$σ_{q} $和$ξ_{q}^{\ prime} $中的质量。结果证实了所有激动的$ω_{C} $和$ω_{B} $ BARYON最近报告的Baryons是P-Wave $ ss $ -Diquark和相应的魅力或Quark的界限，从而预测Regge Trarigeory traightories traightories traightories traightories traightories traightories traightories traightories traightory of More兴奋的$ω__{C} $ {C} $ and $ω____________{b} $ baryons。我们建议一个激动的{$ j^{p} = 5/2^{ - } $} $ω__{b} $状态lhcb在$ 6352 $ MEV左右看不到，并预测所有奇数baryon baryons $σ__{c}（c} c}（2800）/e 29 $ and 2的p波波大量$σ_{b}（6097）$/$ξ_{b}^{\ prime}（6227）$。在相关的潜在夸克模型中进一步给出了计算，以解释所有被考虑的重子的自旋耦合的匹配值，通过该值讨论了这些自旋耦合的缩放定律。
A new scheme of state classification is proposed and applied to analyze masses of the heavy baryons $Ω_{Q}$, $Σ_{Q}$ and $Ξ_{Q}^{\prime}$ in P-waves. The results confirm all excited $Ω_{c}$ and $Ω_{b}$ baryons reported recently by LHCb to be bound states of a P-wave $ss$-diquark and a respective charm or bottom quark, and thereby predict Regge trajectories for more excited $Ω_{c}$ and $Ω_{b}$ baryons. We suggest one excited {$J^{P}=5/2^{-}$} $Ω_{b}$ state to be unseen by LHCb around $6352$ MeV, and predict P-wave masses of all spin-partners of the odd-parity baryons $Σ_{c}(2800)/Ξ_{c}^{\prime}(2942)$ and $Σ_{b}(6097)$/$Ξ_{b}^{\prime }(6227)$. A computation is further given in a relativized potential quark models to explain matched values of spin couplings of all considered baryons, by which a scaling law for these spin couplings is discussed.
