Can the newly $P_{cs}(4459)$ be a strange hidden-charm $\Xi_c\bar{D}^{*}$ molecular pentaquarks?

TLDR: In this article, a one-boson-exchange model was used to analyze a single ε-channel and a coupled εc-bar{D}^* channel with the LHCb Collaboration.

Abstract: Stimulated by the $P_{cs}(4459)$ reported by the LHCb Collaboration, we perform a single $\Xi_c\bar{D}^*$ channel and a coupled $\Xi_c\bar{D}^*/\Xi_c^*\bar{D}/\Xi_c^{\prime}\bar{D}^*/\Xi_c^*\bar{D}^*$ channel analysis by using a one-boson-exchange model. Our results indicate that the newly $P_{cs}(4459)$ cannot be a pure $\Xi_c\bar{D}^*$ molecular state, but a coupled $\Xi_c\bar{D}^*/\Xi_c^*\bar{D}/\Xi_c^{\prime}\bar{D}^*/\Xi_c^*\bar{D}^*$ bound state with $I(J^P)=0(3/2^-)$, where the $\Xi_c\bar{D}^*$ and $\Xi_c^*\bar{D}$ components are dominant. Meanwhile, we find the interactions from the $\Xi_c^{\prime}\bar{D}^*$ system with $0(1/2^-)$, the $\Xi_c^{*}\bar{D}$ system with $1(3/2^-)$, and the $\Xi_c^{*}\bar{D}^*$ system with $1(1/2^-)$ are strongly attractive, where one can expect possible strange hidden-charm molecular or resonant structures near the these thresholds with the assigned quantum numbers.
