摘要：

本文采用单玻色子交换模型，考虑$S$-$D$波混频和耦合沟道效应，研究了$H$ -偶态中粲奇异介子（$D_s, D_s^{*}$）与$T$ -偶态中（反）粲奇异介子（$D_{s1}, D_{s2}^{*}$）之间的相互作用.通过提取所讨论的$H_s\bar{T}_s$和$H_s{T}_s$体系的有效势，我们试图找到相应体系的束缚态解。我们预测了可能的具有隐奇异性的隐魅强子分子态，即，$D_s^{*}\bar D_{s1}+c.c.$状态为$J^{PC}$ = $0^{--}, 0^{-+}$，而$D_s^{*}\bar D_{s2}^{*}+c.c.$状态为$J^{PC}$ = $1^{--}, 1^{-+}$。应用相同的理论框架，我们也讨论了$H_s T_s$系统。不幸的是，$H_s T_s$系统对应的开魅和开奇异分子态的存在可以被排除。

英文摘要：

In this work, we investigate the interactions between the charmed-strange meson ($D_s, D_s^{*}$) in $H$-doublet and the (anti-)charmed-strange meson ($D_{s1}, D_{s2}^{*}$) in $T$-doublet, where the one boson exchange model is adopted by considering the $S$-$D$ wave mixing and the coupled-channel effects. By extracting the effective potentials for the discussed $H_s\bar{T}_s$ and $H_s{T}_s$ systems, we try to find the bound state solutions for the corresponding systems. We predict the possible hidden-charm hadronic molecular states with hidden strangeness, i.e., the $D_s^{*}\bar D_{s1}+c.c.$ states with $J^{PC}$=$0^{--}, 0^{-+}$ and the $D_s^{*}\bar D_{s2}^{*}+c.c.$ states with $J^{PC}$=$1^{--}, 1^{-+}$. Applying the same theoretical framework, we also discuss the $H_s T_s$ systems. Unfortunately, the existence of the open-charm and open-strange molecular states corresponding to the $H_s T_s$ systems can be excluded.
