摘要:

在本工作中,我们构造了色-单重-色-单重型六夸克赝标流,并利用QCD求和规则研究了$\overlineΞ_{cc}Ξ_{cc}$六夸克分子态,预测的质量$M_X \sim 7.2\,\rm{GeV}$支持将$X(7200)$指定为量子数为$J^{PC}=0^{-+}$的$\overlineΞ_{cc}Ξ_{cc}$六夸克分子态. $X(7200)$可以通过$\bar{c}c$和$\bar{q}q$对的融合而衰变,未来可以在$J/ψJ/ψ$、$χ_{c1}χ_{c1}$、$D^*\bar{D}^*$和$D_1\bar{D}_1$不变质谱中寻找$X(7200)$并探索其性质。

英文摘要:

In this work, we construct the color-singlet-color-singlet type six-quark pseudoscalar current to investigate the $\overlineΞ_{cc}Ξ_{cc}$ hexaquark molecular state with the QCD sum rules, the predicted mass $M_X \sim 7.2\,\rm{GeV}$ supports assigning the $X(7200)$ to be the $\overlineΞ_{cc}Ξ_{cc}$ hexaquark molecular state with the quantum numbers $J^{PC}=0^{-+}$. The $X(7200)$ can decay through fusions of the $\bar{c}c$ and $\bar{q}q$ pairs, we can search for the $X(7200)$ and explore its properties in the $J/ψJ/ψ$, $χ_{c1}χ_{c1}$, $D^*\bar{D}^*$ and $D_1\bar{D}_1$ invariant mass spectrum in the future.
