Abstract:-

This analysis shows a search for dark fermion particles produced in association with a heavy neutral gauge boson (Z′). The studied events topology are dimuon and a large missing transverse momentum. We considered the muonic decay of Z′. The analyzed data were the Open Data collected by the CMS detector in proton-proton collisions at the LHC in 2012 and correspond to an integrated luminosity of 11.6 fb−1 at √s= 8 TeV. One benchmark scenario the light vector was used for interpreting the data, based on a simplified model so called the mono-Z′ model. No evidence of dark fermion candidates was found, 95% confidence level limits have been set on both Z′ and dark fermion masses.
