Abstract
A search for long-lived, massive particles predicted by many theories beyondthe Standard Model is presented. The search targets final states with largemissing transverse momentum and at least one high-mass displaced vertex withfive or more tracks, and uses 32.8 fb$^{-1}$ of $\sqrt{s}$ = 13 TeV $pp$collision data collected by the ATLAS detector at the LHC. The observed yieldis consistent with the expected background. The results are used to extract95\% CL exclusion limits on the production of long-lived gluinos with masses upto 2.37 TeV and lifetimes of $\mathcal{O}(10^{-2})$-$\mathcal{O}(10)$ ns in asimplified model inspired by Split Supersymmetry.
