论文摘要
受到$ t_ {ψψ} $状态的最新实验进展的刺激，完全迷人的四夸克光谱镜是由Godfrey-Isgur相关性的Diquark模型的Dint系统地研究了，这是改良的Godfrey-Isgur相关的Diquark模型，具有色彩筛选效果，并具有不重新的Diquark模型。 diquark-antidiquark场景的理论结果建议解释$ t_ {ψ电话}（6200）$，$ t_ {ψψ}（6600）$，$ t_ {ψ电话（6900）$ $ 1p/2s $ - 波，$ 1D/2P $ - 波和$ 2D/3P/4S $ - $ - 沃夫满满的Tetraquark States。由于有足够的实验信息的缺乏，例如，新观察到的$ t_ {ψψ} $状态的均等状态，关于$ t_ {ψψ}（6600）$，$ t_ {ψψ}（6900）（6900）$和$ t_ nistate $ t_ {ψψ}（6600）$，$ t_ {6600）的分配存在不确定性。已经证明，由LHCB，Atlas，CMS和其他合作实施的$ CC \ bar c \ b c $州的进一步实验调查应该在将来继续进行。
Stimulated by the recent experimental progress on the $T_{ψψ}$ states, the fully charmed tetraquark spectroscopy is systemically investigated by dint of the Godfrey-Isgur relativized diquark model, the modified Godfrey-Isgur relativized diquark model with the color screening effects, and the nonrelativistic diquark model. The theoretical results of the diquark-antidiquark scenarios propose to interpret the $T_{ψψ}(6200)$, $T_{ψψ}(6600)$, $T_{ψψ}(6900)$, and $T_{ψψ}(7300)$ structures as the candidates of the $1S$-wave, $1P/2S$-wave, $1D/2P$-wave, and $2D/3P/4S$-wave fully charmed tetraquark states, respectively. On account of the deficiency of sufficient experimental information, e.g., the parities of the newly observed $T_{ψψ}$ states, there are uncertainties about the assignments of the $T_{ψψ}(6600)$, $T_{ψψ}(6900)$, and $T_{ψψ}(7300)$ states. It is demonstrated that the further experimental survey on the $cc\bar c\bar c$ states, implemented by the LHCb, ATLAS, CMS, and other collaborations, ought to be continued in the future.
