论文摘要
在论文中，我们构建了八种颜色的单弦单式五夸克电流，具有杰出的同音素，以研究$ \ bar {d}ξ^{\ prime} $，$ \ bar {d}ξ_c^{*} $，$ \ bar {d} $ \ bar {d}^{*}ξ_c^{*} $通过QCD总规则奇怪的分子状态。数值结果表明，具有较高（下）的Pentaquark群众的核心值略高于（下）（下方）相应的erson-Baryon对的阈值，并支持分配$ p_ {cs}（4459）$作为$ \ bar {d} $ dents $ naste $ p_ cs}（4459）$ an $ ij^p = 0 {\ frac {3} {2}}}^ - $。将来可以将其他预测与实验数据相遇。
In the paper, we construct eight color singlet-singlet type five-quark currents with distinguished isospins to study the $\bar{D}Ξ^{\prime}$, $\bar{D}Ξ_c^{*}$, $\bar{D}^{*}Ξ_c^{\prime}$ and $\bar{D}^{*}Ξ_c^{*}$ molecular states with strangeness via the QCD sum rules. Numerical results show that the central values of the pentaquark masses with higher (lower) isospin are slightly above (below) the thresholds of the corresponding meson-baryon pairs, and support assigning the $P_{cs}(4459)$ as the $\bar{D}Ξ_c^{*}$ molecular state with the quantum numbers $IJ^P=0{\frac{3}{2}}^-$. The other predictions can be confronted to the experimental data in the future.
