Hussein Hide abstract | Show figures | Show BibTeX | Show discussion | View PDF | 2109.11274v1 In this work, we present a search for Dark Matter candidate particles produced at the Large Hadron Collider, the process of the production of DM particles, alongside a new hypothetical gauge boson denoted by Z′, is governed by a model called Mono-Z′. The analyzed events contain dimuon plus a large missing transverse momentum. The analyzed data were the CMS open Monte Carlo samples and the open data samples collected by the CMS detector for the proton-proton collisions at a center-of-mass energy of 8 TeV in 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 approach of the Mono-Z′ model, and the effective field theory approach of the model. No evidence for the existence of dark matter candidates was found, and 95% confidence level limits were set on the mass of the Z′, the mass of the dark matter candidate particle, and the cutoff scale of the effective field theory.
