Search for dark Higgs boson production in pp events at √s = 13 TeV with the ATLAS detector at the LHC
This thesis presents the design of a signal region, as well as two control regions to constrain the tt ̄ background, in the search for the theorized dark sector process qq ̄ → Z′∗ → Z′s with s → W W → qq ̄lν and Z′ → χχ(invisible). In this process, dark matter is produced as a new heavy vector boson...
