Search for Dark Matter in the MET+jet topology at ATLAS

The search for Dark Matter in the mono-jet topology conducted by ATLAS with the 2015 and 2016 data delivered by the LHC at $\sqrt{s}=13$~TeV is reported in these slides. No excess over the Standard Model background is observed and results are interpreted in terms of exclusion limits. Several Dark Matter, SUSY and ADD scenarios are reported. ATLAS Dark Matter limits are also compared to those obtained by direct detection experiments.
