Forward-proton-tagged photon-induced production of a leptophobic Z' mediator would exclude mZ' below about 1.4 TeV at 14 TeV and 3000 fb^-1, with a dark matter mass bound near 550 GeV for the vector benchmark.

abstract
A search is presented for dark matter produced in association with a hadronically decaying W or Z boson using 3.2 /fb of pp collisions at $\sqrt{s}$=13 TeV recorded by the ATLAS detector at the Large Hadron Collider. Events with a hadronic jet compatible with a W or Z boson and with large missing transverse momentum are analysed. The data are consistent with the Standard Model predictions and are interpreted in terms of both an effective field theory and a simplified model containing dark matter.

Search for Vector-mediated Dark Matter at the LHC with Forward Proton Tagging
Forward-proton-tagged photon-induced production of a leptophobic Z' mediator would exclude mZ' below about 1.4 TeV at 14 TeV and 3000 fb^-1, with a dark matter mass bound near 550 GeV for the vector benchmark.
