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
We consider models where a massive spin-two resonance acts as the mediator between Dark Matter (DM) and the SM particles through the energy-momentum tensor. We examine the effective theory for fermion, vector and scalar DM generated in these models and find novel types of DM-SM interaction never considered before. We identify the effective interactions between DM and the SM quarks when the mediator is integrated out, and match them to the gravitational form factors relevant for spin-independent DM-nucleon scattering. We also discuss the interplay between DM relic density conditions, direct detection bounds and collider searches for the spin-two mediator.
