| contents | We investigate the femtoscopic correlation functions of systems associated with the $Ω(2012)$, $Ω(2380)$, and $Ω_c(3120)$ resonances, with the aim of elucidating their internal structures. By employing effective potential models that incorporate both $s$-wave and $d$-wave interactions, we calculate the correlation functions for the relevant coupled channels. Our numerical results reveal pronounced enhancement structures in the $Ξ^0K^-$ and $Ξ_c^+K^-$ correlation functions, which provide direct evidences for the dynamically generated $Ω(2012)$ and $Ω_c(3120)$ states. Furthermore, significant low-momentum enhancements are observed in the $Ξ^{*0}K^-$ and $Ξ^{*0}K^{*-}$ channel, which are attributed to the $Ω(2012)$ and $Ω(2380)$ resonances. These theoretical calculations provide crucial insights for future high-precision measurements at the LHC and RHIC, offering a novel and independent approach to determine the dynamically generated hadronic molecular nature of these $Ω$ excited states. |
