标题： Exploring the spectroscopic features of double-strangeness tetraquark states

摘要： 自LHCb合作组发现$T_{cc}$双重粲四夸克以来，重夸克理论研究领域迅速发展，人们对轻夸克扇区的兴趣也不断增加。在此研究中，采用夸克模型系统地分析双重奇异四夸克系统。考虑了介子-介子构型和双夸克-反双夸克构型。评估了各种量子数下强子对之间的相互作用，以及束缚态和共振的可能性。结果表明，在单通道估算中存在两个量子数为$I(J^{P})=0(1^{+})$的束缚态$ \bar{K}^{\ast }\bar{K}$和$\bar{K}^{\ast }\bar{K}^{\ast}$。此外，通过考虑两种构型之间的通道耦合，得到一个量子数为$I(J^{P})=0(1^{+})$且质量约为$1310$兆电子伏的束缚态。 此外，通过共振接地法的应用，在$I(J^{P})=0(1^{+})$ $\ssqq$ 系统中识别出一个共振态，其估算的质量约为 1783 MeV，衰变宽度约为 17 MeV。 显示英文摘要

摘要： Since the discovery of the $T_{cc}$ double-charm tetaquark by the LHCb collaboration, the field of the theoretical research on heavy quarks has advanced rapidly, with increasing interest in exploring the light quark sector. In this study, the quark model is employed to systematically analyze the double-strange tetraquark system. Both the meson-meson configuration and diquark-antidiquark configuration are considered. The interactions between hadron pairs under various quantum numbers, as well as the possibilities of bound states and resonances, are evaluated. The results indicate the presence of two bound states, $ \bar{K}^{\ast }\bar{K}$ and $\bar{K}^{\ast }\bar{K}^{\ast}$, with quantum number $I(J^{P})=0(1^{+})$ in single-channel estimations. Additionally, by considering the channel coupling between the two configurations, a bound state with quantum numbers $I(J^{P})=0(1^{+})$ and a mass of approximately $1310$ MeV is obtained. Moreover, through the application of Resonance Ground Method, a resonance state is identified in the $I(J^{P})=0(1^{+})$ $\ssqq$ system, with an estimated mass of around 1783 MeV and a decay width of approximately 17 MeV.
