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 (2304.09483v4)

Published 19 Apr 2023 in hep-ex and hep-ph

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.
