论文摘要
在这项工作中，我们暂定将$ p_ {cs}（4338）$确定为$ \ bar {d}ξ_c$分子状态，并区分当前操作员的issospins，以探索$ \ bar {d} d}ξ_c$，$ \ bar {d} d} d} d} d}λ_c$，$ \ bar} d} d} $\bar{D}_sΛ_c$, $\bar{D}^*Ξ_c$, $\bar{D}^*Λ_c$, $\bar{D}^*_sΞ_c$ and $\bar{D}^*_sΛ_c$ molecular states without strange, with strange and with double strange in the framework of the QCD sum rules in details.目前的探索倾向于将$ p_ {cs}（4338）$（$ p_ {cs}（4459）$）作为$ \ bar {d}ξ_c$（$ \ bar {d}^*ξ_C$），带有spin-parity $ j^p =^par = {$ （$ {\ frac {3} {2}}^ - $）和isospin $（i，i_3）=（0,0）$，在$ j/ψς^0/η_cς^0/η_cpς^0 n n nintutions unverutions的$ j/ψdimnisture nisture decipher中，用isospin $（i，i，i_3）=（1,0）$观察他们的表亲。
In this work, we tentatively identify the $P_{cs}(4338)$ as the $\bar{D}Ξ_c$ molecular state, and distinguish the isospins of the current operators to explore the $\bar{D}Ξ_c$, $\bar{D}Λ_c$, $\bar{D}_sΞ_c$, $\bar{D}_sΛ_c$, $\bar{D}^*Ξ_c$, $\bar{D}^*Λ_c$, $\bar{D}^*_sΞ_c$ and $\bar{D}^*_sΛ_c$ molecular states without strange, with strange and with double strange in the framework of the QCD sum rules in details. The present explorations favor identifying the $P_{cs}(4338)$ ($P_{cs}(4459)$) as the $\bar{D}Ξ_c$ ($\bar{D}^*Ξ_c$) molecular state with the spin-parity $J^P={\frac{1}{2}}^-$ (${\frac{3}{2}}^-$) and isospin $(I,I_3)=(0,0)$, the observation of their cousins with the isospin $(I,I_3)=(1,0)$ in the $J/ψΣ^0/η_cΣ^0$ invariant mass distributions would decipher their inner structures.
