- In the present work, we study the possible production of the dark Higgs boson ($h_{D}$) candidates, which originated from a simplified-model scenario based on the Mono-Z$^{\prime}$ model, in association with a neutral gauge boson (Z$^{\prime}$). This study has been performed by studying events with dimuon plus missing transverse energy produced in the simulated electron-positron collisions at the foreseen Future Circular Collider in the Electron-Positron collision mode (FCC-ee), operating at 240 GeV center of mass energy and integrated luminosity of 10.8 ab$^{-1}$. In case no new physics has been discovered, we set upper limits at a 95\% confidence level on the mass of the dark Higgs.
