本文区分了内插流的电荷合取，在算符乘积展开中一致地计算了10维真空凝聚的贡献，用QCD求和规则研究了隐粲四夸克态的质量和极余，并首次详细地探讨了能量标度的依赖性。预测和支持将和[或]分别指定为和双夸克-反双夸克类型四夸克态。
In this article, we distinguish the charge conjunctions of the interpolating currents, calculate the contributions of the vacuum condensates up to dimension 10 in a consistent way in the operator product expansion, study the masses and pole residues of thehidden charmed tetraquark states with the QCD sum rules, and explore the energy-scale dependence in detail for the first time. The predictionsandsupport assigning theand[or] as theanddiquark-antidiquark type tetraquark states, respectively.
