论文摘要
在这项工作中，我们调查了$ h $ -doublet和（anti-）Charmed-Strange meson（$ d_ {s1}，d_ {s2}}^{*} $ the $ t $ - dlublet $ waver-混合和耦合通道效应。通过提取讨论的$ H_S \ bar {t} _s $和$ h_s {t} _s $ Systems的有效潜力，我们尝试找到相应系统的界面解决方案。我们预测具有隐藏陌生性的可能的隐藏障碍性分子状态，即$ d_s^{*} \ bar d_ {s1}+c.c. $ c. $ c. $ c. $ co. lith $ j^{pc} $ = $ 0^{ - }，0^{ - +} $ j^{pc} $ = $ 1^{ - }，1^{ - +} $。应用相同的理论框架，我们还讨论了$ H_S T_S $系统。不幸的是，可以排除与$ h_s t_s $系统相对应的开放式和开放式分子状态的存在。
In this work, we investigate the interactions between the charmed-strange meson ($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.
