In this work, we construct the color-singlet-color-singlet type six-quark pseudoscalar current to investigate the ΞccΞcc hexaquark molecular state with the QCD sum rules, the predicted mass MX7.2GeV supports assigning the X(7200) to be the ΞccΞcc hexaquark molecular state with the quantum numbers JPC=0+. The X(7200) can decay through fusions of the c¯c and q¯q pairs, we can search for the X(7200) and explore its properties in the J/ψJ/ψ, χc1χc1, DD¯ and D1D¯1 invariant mass spectrum in the future.

在这项工作中,我们构建了颜色-单线态-颜色-单线态六夸克伪标量流来研究 ΞCCΞCC 具有 QCD 和规则的六夸克分子态,预测质量 X7.2电子伏特 支持分配 X(7200) 成为 ΞCCΞCC 具有量子数的六夸克分子态 JC=0-+. 这X(7200) 可以通过融合衰变 C¯Cq¯q 对,我们可以搜索 X(7200) 并探索其在 J/ψJ/ψ, χC1χC1, DD¯D1D¯1 未来的不变质谱。
