Strong decays of the newly $P_{cs}(4459)$ as a strange hidden-charm $Ξ_c\bar{D}^*$ molecule
Abstract: In our former work [arXiv:2011.07214], the $P_{cs}(4459)$ observed by the LHCb Collaboration can be explained as a coupled strange hidden-charm $\Xi_c\bar{D}/\Xi_c^\bar{D}/\Xi_c'\bar{D}/\Xi_c^\bar{D}*$ molecule with $I(JP)=0(3/2-)$. Here, we further discuss the two-body strong decay behaviors of the $P_{cs}(4459)$ in the meson-baryon molecular scenario by input the former obtained bound solutions. Our results support the $P_{cs}(4459)$ as the strange hidden-charm $\Xi_c\bar{D}*$ molecule with $I(JP)=0(3/2-)$. The relative decay ratio between $\Lambda_cD_s*$ and $J/\psi\Lambda$ is around 10, where the partial decay width for the $\Lambda_cD_s*$ channel is around 0.6 to 2.0 MeV.
