论文摘要
在这项工作中，我们对可能的分子状态进行了系统研究$σ_C^{（*）}σ_c^{（*）} $，和$λ_Cς_C^{（*）} $。借助重夸克手性有效的拉格朗日人，用$π$，$ρ$，$η$，$ω$，$ ϕ $和$σ$交换来描述互动。构建潜在的核，并插入到准盐酸的方程式中。通过搜索散射幅度的极线来研究所考虑的相互作用的结合状态。结果表明，在当前工作中考虑的隐藏障碍和双链系统中都存在强大的吸引力，并且在大多数系统中都可以产生约束状态。通过$ \ rm \ bar {p} anda $，提出了有关这些分子状态的更多实验研究，该研究提出了有关这些分子状态的更多实验。
In this work, we perform a systematic study of possible molecular states composed of two charmed baryons including hidden-charm systems $Λ_c\barΛ_c$, $Σ_c^{(*)}\barΣ_c^{(*)}$, and $Λ_c\barΣ_c^{(*)}$, and corresponding double-charm systems $Λ_cΛ_c$, $Σ_c^{(*)}Σ_c^{(*)}$, and $Λ_cΣ_c^{(*)}$. With the help of the heavy quark chiral effective Lagrangians, the interactions are described with $π$, $ρ$, $η$, $ω$, $ϕ$, and $σ$ exchanges. The potential kernels are constructed, and inserted into the quasipotential Bethe-Salpeter equation. The bound states from the interactions considered is studied by searching for the poles of the scattering amplitude. The results suggest that strong attractions exist in both hidden-charm and double-charm systems considered in the current work, and bound states can be produced in most of the systems. More experiment studies about these molecular states are suggested though the nucleon-nucleon collison at LHC and nucleon-antinucleon collison at $\rm \bar{P}ANDA$.
