Search for dark matter production in association with the Z' boson at the LHC in pp collisions at \begin{document}$ {{\sqrt{s}}} $\end{document} = 8 TeV using Monte Carlo simulations

This analysis evaluates the possibility of the search for Dark Matter (DM) particles using events with a Z \begin{document}$ ^{\prime} $\end{document} heavy gauge boson and a large missing transverse momentum at the Large Hadron Collider (LHC). We consider the muonic decay of Z \begin{document}$ ^{\prime} $\end{document} . The analyzed Monte Carlo samples were the Open simulated files produced by the Compact Muon Solenoid (CMS) collaboration for proton-proton collisions, corresponding to an integrated luminosity of the LHC run-I with 19.7 fb \begin{document}$ ^{-1} $\end{document} at \begin{document}$ \sqrt{s} = $\end{document} 8 TeV. Two scenarios, namely a simplified benchmark scenario, called Dark Higgs, and the effective field theory (EFT) formalism, were used for interpretations. Limits were set on Z \begin{document}$ ^{\prime} $\end{document} , dark matter masses, and the cutoff scale of the EFT.
