论文摘要
在本文中，我们研究了标量，轴向向量，矢量和张tensor diquark-antidiquark型$ cc \ bar {c} \ bar {c} $ tetraquark状态的第一个径向激发态，并具有QCD和tetraquark的态度，并获得质量和极点，然后获得质量和极点，然后我们使用regge轨迹来获得第二个radial radial radial ractial rycial ryatial rycial rack的radial兴奋。 The predicted masses support assigning the broad structure from 6.2 to 6.8 GeV in the di-$J/ψ$ mass spectrum to be the first radial excited state of the scalar, axialvector, vector or tensor $cc\bar{c}\bar{c}$ tetraquark state, and assigning the narrow structure at about 6.9 GeV in the di-$J/ψ$ mass spectrum to be the second radial excited state标量或轴向向量$ cc \ bar {c} \ bar {c} $ tetraquark state。
In this article, we study the first radial excited states of the scalar, axialvector, vector and tensor diquark-antidiquark type $cc\bar{c}\bar{c}$ tetraquark states with the QCD sum rules and obtain the masses and pole residues, then we use the Regge trajectory to obtain the masses of the second radial excited states. The predicted masses support assigning the broad structure from 6.2 to 6.8 GeV in the di-$J/ψ$ mass spectrum to be the first radial excited state of the scalar, axialvector, vector or tensor $cc\bar{c}\bar{c}$ tetraquark state, and assigning the narrow structure at about 6.9 GeV in the di-$J/ψ$ mass spectrum to be the second radial excited state of the scalar or axialvector $cc\bar{c}\bar{c}$ tetraquark state.
