Search for the production of dark matter in the framework of Mono-Z$^{\prime}$ portal at the ILC simulated electron-positron collisions at $\sqrt{s} = 500$ GeV (2311.13924v3)

Abstract: In the present work, we study the possible production of the light neutral gauge boson (Z$^{\prime}$) candidates, which originated from a simplified-model scenario based on the Mono-Z$^{\prime}$ model, in association with dark matter. This study has been performed by studying events with dimuon plus missing transverse energy produced in the simulated electron-positron collisions at the foreseen International Linear Collider (ILC), operating at 500 GeV center of mass energy and integrated luminosity of 1000 fb$^{-1}$. In case no new physics has been discovered, we set upper limits at 95\% confidence level on the masses of various particles in the model as, spin-1 (Z$^{\prime}$), as well as the fermionic dark matter.
