Analysis of the $P_{cs}(4338)$ and related pentaquark molecular states via the QCD sum rules

Xiu-Wu Wang, Zhi-Gang Wang

In this work, we tentatively identify the $P_{cs}(4338)$ as the $\bar{D}{\Xi }_c$ molecular state, and distinguish the isospins of the current operators to explore the $\bar{D}{\Xi }_c$, $\b…
