Analytical reinterpretation of ATLAS dark matter mediator searches with final-state jets

Understanding dark matter (DM) is one of the main challenges in modern high-energy physics and cosmology. Alongside direct and indirect detection experiments, one could also produce and discover DM in collider experiments, assuming there is some interaction between DM and the Standard Model. One form this interaction could take is one mediated by a new vector or axial vector boson. Furthermore, if DM can be resonantly produced by such a mechanism, the mediator itself could also be discovered decaying back into quarks. One such search, using the LHC and the ATLAS detector, for jets with an associated photon in the final state, is described, together with an analytical method for the reinterpretation of non-discovery limits, for different model parameters with respect to those generated in simulation.
