论文摘要
我们研究具有两个魅力单元的两种巴里族系统，以寻找可能的约束状态或共振。所有两种两种两种两种两种相互作用始终源自在光味的强子现象学中调谐的组成夸克模型：光谱和相互作用。重型夸克的存在使两体相互作用比在光味领域中更简单。我们的结果表明，狭窄的两体共振，量子数$（i，j^p）=（0,0^+）$。它位于$σ_Cς_C$阈值下方的6.2 meV，宽度为4.7 meV。上述两体状态有助于生成$nσ_cς_c$ resonance，其量子数$（i，j^p）=（1/2,1/2^+）$，分离能量为0.2 meV。
We study two- and three-baryon systems with two units of charm looking for possible bound states or resonances. All two-baryon interactions are consistently derived from a constituent quark model tuned in the light-flavor hadron phenomenology: spectra and interactions. The presence of the heavy quarks makes the two-body interactions simpler than in the light-flavor sector. Our results show a narrow two-body resonance with quantum numbers $(I,J^P)=(0,0^+)$. It is located 6.2 MeV below the $Σ_cΣ_c$ threshold and has a width of 4.7 MeV. The foregoing two-body state contributes to generate a $N Σ_cΣ_c$ resonance with quantum numbers $(I,J^P)=(1/2,1/2^+)$ and a separation energy of 0.2 MeV.
