  7. Abstract:
  8. Today, many evidences, including the distribution of galactic velocities, gravitational lensing observations, and the cosmic microwave background, show that there exist dark matter (non-baryon matter) in large-scale cosmological structures that are stable, free of charge and without color, which has gravitational interaction like normal matter. The hypothesis that weakly interacting massive particles (WIMPs) as a dark matter candidate with mass range of several tens of GeV to several teV and with the typical couplings of Electroweak order of magnitude, is an attractive and desirable model, Which naturally explains the density of cosmic dark matter in agreement with observations. Alongside missing energy searches at large Hadron Collider (LHC), efforts for direct and indirect detection of Dark matter offer complementary fronts where dark matter can be searched for and provide constraints on the cross-section of dark matter interaction with the standard model. Many of the generalizations of the standard model, predict large missing energy signs in LHC. Events that contain a lot of missing transverse energy (MET), along with light mediator, leptons and energetic jets, have distinct characteristics compared to the standard model used to search for new physics such as dark matter. Simplified models by including in a minimal model the extra particles and new interactions with the standard model, offer a powerful approach for analyzing "mono-X" signature of Dark Matter production at LHC. In this regard, We introduce Muon charge asymmetry in proton-proton collision at LHC as a precisely measured observable, which allows investigation for any deviation from the standard model. According to the statistical and systematic error range, one can set constraints on the parametric space of simplified models. The present study focuses on the simplified model involving s-channel exchange of a new Z' vector boson between dark sector and particles of the standard model. For this purpose, We have generated mono-W events, pp → W± + χ¯χ, in MadGraph. Considering the leptonic decays of W, We determine the 14 TeV LHC reach of the mono-W searches with 300 and 3000 fb^{-1} of data. The resulting constraints on s-channel Z' mediator model are also compared with the recent results of the DM direct detection such as LUX experiment
