标题： Strange hidden-charm tetraquarks in constituent quark models

摘要： 受BESIII合作组最新报道的$Z_{cs}(3985)^{-}$的启发，我们系统地研究了奇异的隐粲四夸克系统$cs\bar{c}\bar{u}$，具有两种结构：介子-介子和二夸克-反二夸克。这里使用了两种夸克模型：手征夸克模型（ChQM）和夸克离域色屏蔽模型（QDCSM）。在两种夸克模型中都得到了相似的结果。在ChQM或QDCSM中都没有任何束缚态，这排除了所报道的$Z_{cs}(3985)^{-}$的分子态解释（$D_{s}D^{*}/D_{s}^{*}D/D_{s}^{*}D^{*}$）。 然而，二夸克-反二夸克$cs\bar{c}\bar{u}$系统的有效势显示了在质量范围为$3916.5\sim 3964.6$兆电子伏特对于$IJ^{P}=\frac{1}{2} 0^{+}$，$4008.8\sim 4091.2$兆电子伏特对于$IJ^{P}=\frac{1}{2} 1^{+}$，$4246.8\sim 4418.1$兆电子伏特对于$IJ^{P}=\frac{1}{2} 2^{+}$的一些共振态的可能性。 因此，观察到的$Z_{cs}(3985)^{-}$状态可能被解释为由$cs\bar{c}\bar{u}$与$IJ^{P}=\frac{1}{2} 0^{+}$或$IJ^{P}=\frac{1}{2} 1^{+}$组成的紧凑共振态。 对应开放通道的散射过程的研究正在进行中，以验证这一结论。 显示英文摘要

摘要： Inspired by the newly reported $Z_{cs}(3985)^{-}$ by the BESIII Collaboration, we systematically investigate the strange hidden-charm tetraquark systems $cs\bar{c}\bar{u}$ with two structures: meson-meson and diquark-antidiquark. Two quark models: the chiral quark model (ChQM) and the quark delocalization color screening model (QDCSM) are used here. Similar results are obtained in both two quark models. There is no any bound state in either ChQM or QDCSM, which excludes the molecular state explanation ($D_{s}D^{*}/D_{s}^{*}D/D_{s}^{*}D^{*}$) of the reported $Z_{cs}(3985)^{-}$. However, the effective potentials for the diquark-antidiquark $cs\bar{c}\bar{u}$ systems shows the possibility of some resonance states with mass range of $3916.5\sim 3964.6$ MeV for $IJ^{P}=\frac{1}{2} 0^{+}$, $4008.8\sim 4091.2$ MeV for $IJ^{P}=\frac{1}{2} 1^{+}$, $4246.8\sim 4418.1$ MeV for $IJ^{P}=\frac{1}{2} 2^{+}$. So the observed $Z_{cs}(3985)^{-}$ state is possible to be explained as a compact resonance state composed of $cs\bar{c}\bar{u}$ with $IJ^{P}=\frac{1}{2} 0^{+}$ or $IJ^{P}=\frac{1}{2} 1^{+}$. The study of the scattering process of corresponding open channels is under way to check this conclusion.
