Search for Dark Matter in the Mono$$-{\mathrm W/Z(q}\bar{q})$$ Channel at the ATLAS Experiment

Abstract

We present a search for Dark Matter (DM) particles production in the mono-\(W/Z(q\bar{q})\) channel using pp collision data at a centre-of-mass energy of \(\sqrt{s}\) = 13 TeV corresponding to an integrated luminosity of 36.1 \(\mathrm{fb}^{-1}\), recorded by the ATLAS detector at the Large Hadron Collider (LHC). No significant excess over the Standard Model (SM) prediction is observed. The search results are interpreted in terms of limits on invisible Higgs boson decays into DM particles, constraints on the parameter space of the simplified vector-mediator model and generic upper limits on the visible cross section for \(W/Z +\)DM production.
