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

Abstract

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