Searches for Dark Matter in Events with Hadronic Activity at ATLAS

The astrophysical evidence of dark matter provides some of the most compelling clues to the nature of physics beyond the Standard Model. From these clues, ATLAS has developed a broad and systematic search program for dark matter production in LHC collisions. The results of searches in 13 TeV pp collisions for dark matter using events with large missing transverse momentum and hadronic activity is presented along with the complementary searches for the dark matter mediator in resonance searches.
