论文摘要
在这项工作中，我们采用单验交换模型来研究$ d^{（*）} k^{（*）} $互动。使用相同的参数，我们可以同时再现$ d_ {s0}（2317）$，$ d_ {s1}（2460）$和$ t_ { $ d_ {s0}（2317）$，$ d_ {s1}（2460）$，和$ t_ {c \ bar {s}}}^{a0（++）}（2900）$被视为$ dk [i（j^p）= 0（j^p）= 0（j^p）= 0（0^+）$，$，$，$，$，$，$，$，$，$，$，和$ d^k [$ n（1^k [$） $ d^*k^*[1（0^+）] $ charmed-strange分子状态。此外，我们扩展到研究$λ_ck^{（*）} $和$σ_ck^{（*）} $互动，并预测两个可能的Charmed-strange分子pentaquarks，单个$σ_ck^*$ state at $ i（j^p）= 1/2（1/2^ - ）$和$ 3/2（3/2^ - 2^^$ i（j^p）在考虑了耦合的频道效果之后，我们的结果表明，$λ_ck^*/σ_ck^*$分子状态与$ i（j^p）= 1/2（1/2^ - ）$，$σ_ck/λ_ck/λ_ck^*$ Molecular State uncular can $ i（j^p）$ i（j^p）候选人，$λ_ck^*（{}^2S_ {1/2}）$和$σ_ck（{}^2s_ {1/2}）$分别是主频道。
In this work, we adopt the one-boson-exchange model to study the $D^{(*)}K^{(*)}$ interactions. With the same parameters, we can simultaneously reproduce the masses of the $D_{s0}(2317)$, $D_{s1}(2460)$, and $T_{c\bar{s}}^{a0(++)}(2900)$ recently observed by the LHCb collaboration in the hadronic molecular picture, where the $D_{s0}(2317)$, $D_{s1}(2460)$, and $T_{c\bar{s}}^{a0(++)}(2900)$ are regarded as the $DK[I(J^P)=0(0^+)]$, $D^*K[0(1^+)]$, and $D^*K^*[1(0^+)]$ charmed-strange molecular states, respectively. In addition, we extend to study the $Λ_cK^{(*)}$ and $Σ_cK^{(*)}$ interactions and predict two possible charmed-strange molecular pentaquarks, the single $Σ_cK^*$ state with $I(J^P)=1/2(1/2^-)$ and $3/2(3/2^-)$. After considering the coupled channel effects, our results show that the coupled $Λ_cK^*/Σ_cK^*$ molecular state with $I(J^P)=1/2(1/2^-)$ and the coupled $Σ_cK/Λ_cK^*$ molecular state with $I(J^P)=1/2(1/2^-)$ can be good hadronic molecular candidates, the $Λ_cK^*({}^2S_{1/2})$ and $Σ_cK({}^2S_{1/2})$ are the dominant channels, respectively.
