Search for the production of dark fermion candidates in association with heavy neutral gauge boson decaying to dimuon in proton-proton collisions at $\sqrt{s}=8$ TeV using the CMS open data

Abstract

This analysis shows a search for dark fermion particles produced in association with a heavy neutral gauge boson (Z${}^{\prime }$). The studied events topology are dimuon and a large missing transverse momentum. %We considered the muonic decay of Z${}^{\prime }$. 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 $\sqrt{s}=$ 8 TeV. One benchmark scenario the light vector was used for interpreting the data, based on a simplified model so called the mono-Z${}^{\prime }$ model. No evidence of dark fermion candidates was found, 95$\%$ confidence level limits have been set on both Z${}^{\prime }$ and dark fermion masses.
