In this work, we present a search for the possible production of Dark Matterparticles at the Large Hadron Collider alongside a new hypothetical gauge bosondenoted by Z$^{\prime}$, which is governed by a model called Mono-Z$^{\prime}$.The topology of the studied events is dimuons plus large missing transversemomentum. The analyzed data were the CMS open data samples collected by the CMSdetector, in addition to the CMS open Monte Carlo samples, for theproton-proton collisions at 8 TeV center of mass energy during 2012, whichcorrespond to an integrated luminosity of 11.6 fb$^{-1}$. Two benchmarksscenarios were used for interpreting the data, the Dark Higgs scenario as asimplified scenario of the Mono-Z$^{\prime}$ model and the effective fieldtheory formalism of the same model. No evidence for the existence of darkmatter candidates was found. Consequently, 95$\%$ confidence level limits wereset on the masses of the Z$^{\prime}$ and the cutoff scale of the effectivefield theory.

Search for the production of dark matter candidates in association with  heavy dimuon resonance using the CMS open data for pp collisions at  $\sqrt{s}$ = 8 TeV
