论文摘要
奇怪的隐藏魅力pentaquark系统的动态计算$λ_{c \ bar {c}} $在夸克离域颜色筛选模型的框架中执行。计算两个簇之间的有效电位以研究重子与介子之间的相互作用。动态计算表明，具有$ ij^{p} = 0 \ frac {1} {2} {2}^{ - } $和$ ij^{p} = 0 \ frac {3} {3} {2} {2}^{ - } $ bong and bouncl cannels-coupleling的状态。这两个系统的能量分别为4094.3 MEV和4207.4 MEV。这两个$λ_{c \ bar {c}} $状态是有可能吸引值得在实验中搜索的五夸克候选人的。鉴于，对于具有Isospin $ i = 1 $的系统，所有渠道的有效潜力都是令人反感的，并且这些系统没有任何界限。
A dynamical calculation of the strange hidden charm pentaquark systems $Λ_{c\bar{c}}$ is performed in the framework of the quark delocalization color screening model. The effective potentials between two clusters are calculated to investigate the interaction between the baryons and mesons. The dynamic calculations indicate that the strange hidden charm pentaquark system with $IJ^{P}=0\frac{1}{2}^{-}$ and $IJ^{P}=0\frac{3}{2}^{-}$ can form bound states with the help of the channel-coupling. The energies of these two system are 4094.3 MeV and 4207.4 Mev, respectively. These two $Λ_{c\bar{c}}$ states are possible to be intriguing pentaquark candidates which are worth searching in experiments. Whereas, for the systems with isospin $I=1$, the effective potentials of all channels are repulsive, and there is no any bound state for these systems.
