A search for long-lived, massive particles predicted by many theories beyond the Standard Model is presented. The search targets final states with large missing transverse momentum and at least one high-mass displaced vertex with five or more tracks, and uses 32.8 fb⁻¹ of √s = 13 TeV pp collision data collected by the ATLAS detector at the LHC. The observed yield is consistent with the expected background. The results are used to extract 95% C.L. exclusion limits on the production of long-livedgluinos with masses up to 2.37 TeV and lifetimes of O(10⁻²)−O(10) ns in a simplified model inspired by split supersymmetry.
