Search for the production of dark matter candidates in association with heavy dimuon resonance using the CMS open data for pp collisions at $\sqrt{s}$ = 8 TeV

Abstract

In this work, we present a search for the possible production of Dark Matter particles at the Large Hadron Collider alongside a new hypothetical gauge boson denoted by Z${}^{\prime }$, which is governed by a model called Mono-Z${}^{\prime }$. The topology of the studied events is dimuons plus large missing transverse momentum. The analyzed data were the CMS open data samples collected by the CMS detector, in addition to the CMS open Monte Carlo samples, for the proton-proton collisions at 8 TeV center of mass energy during 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 scenario of the Mono-Z${}^{\prime }$ model and the effective field theory formalism of the same model. No evidence for the existence of dark matter candidates was found. Consequently, 95$\%$ confidence level limits were set on the masses of the Z${}^{\prime }$ and the cutoff scale of the effective field theory.
