Search for long-lived, massive particles in events with displaced vertices and missing transverse momentum in √s=13 TeV pp collisions with the ATLAS detector
MetadataVis metadata som liste
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-lived gluinos with masses up to 2.37 TeV and lifetimes of O(10^−2)−O(10) ns in a simplified model inspired by split supersymmetry.
