Analysis of the scalar doubly charmed hexaquark state with QCD sum rules

In this article, we study the scalar-diquark-scalar-diquark-scalar-diquark type hexaquark state with the QCD sum rules by carrying out the operator product expansion up to the vacuum condensates of dimension 16. We obtain the lowest hexaquark mass $6.60_{-0.09}^{+0.12}\mathrm{G}\mathrm{e}\mathrm{V}$, which can be confronted to the experimental data in the future.
