description In this report we present the latest results from the ATLAS experiment on the search of dark matter production in association with a hardronically decaying vector boson. The search is performed on proton-proton collisions produced by the Large Hadron Collider with the first two years of Run 2 data taking by ATLAS. The simplified vector-mediator model and the invisible Higgs model are considered in this search with a W or Z boson in the final state, while the dark-fermion model and dark-Higgs model are considered where a potentially new vector boson Z′ is presented. No significant excess over the Standard Model prediction is observed. The results are interpreted in terms of constraints on the parameter space of the simplified vector-mediator model, limits on the branching ratio of Higgs boson decay into dark matter particles, as well as the highest possible production cross section of dark-fermion and dark-Higgs models.
