Abstract

In this study, we conducted a search for dark matter using a part of the data recorded by the CMS experiment during run-I of the LHC in 2012 with a center of mass energy of 8 TeV and an integrated luminosity of 11.6 fb−1. These data were gathered from the CMS open data. Dark matter, in the framework of the simplified model (mono-Z ), can be produced from proton-proton collisions in association with a new hypothetical gauge boson, Z . Thus, the search was conducted in the dimuon plus large missing transverse momentum channel. One benchmark scenario of mono-Z , which is known as light vector, was used for interpreting the CMS open data. No evidence of dark matter was observed, and exclusion limits were set on the masses of dark matter and Z at 95% confidence level.
