Dark Sector searches with jets

The presence of a non-baryonic Dark Matter (DM) component in the Universe is inferred from the observation of its gravitational interaction. If Dark Matter interacts weakly with the Standard Model (SM) it could be produced at the LHC. The ATLAS and CMS experiments have developed a broad search program for DM candidates, including resonance searches for the mediator which would couple DM to the SM and searches with large missing transverse momentum which is produced in association with other particles (e.g. light and heavy quarks, Z and H bosons) called mono-X searches. Additionally, searches have been conducted in models where the Higgs boson provides a portal to the Dark Sector leading to either invisible Higgs boson decays or decays with long lived particle requiring special reconstruction techniques. The results of recent searches on 13 TeV pp data, their interplay and interpretation will be presented.
