  In this work, we present a search for the possible production of Dark Matter
particles at the Large Hadron Collider alongside a new hypothetical gauge boson
denoted by Z$^{\prime}$, which is governed by a model called Mono-Z$^{\prime}$.
The topology of the studied events is dimuons plus large missing transverse
momentum. The analyzed data were the CMS open data samples collected by the CMS
detector, in addition to the CMS open Monte Carlo samples, for the
proton-proton collisions at 8 TeV center of mass energy during 2012, which
correspond to an integrated luminosity of 11.6 fb$^{-1}$. Two benchmarks
scenarios were used for interpreting the data, the Dark Higgs scenario as a
simplified scenario of the Mono-Z$^{\prime}$ model and the effective field
theory formalism of the same model. No evidence for the existence of dark
matter candidates was found. Consequently, 95$\%$ confidence level limits were
set on the masses of the Z$^{\prime}$ and the cutoff scale of the effective
field theory.
