A search for supersymmetry in the Z+jets+ETmiss final state with ATLAS

This poster presents a search for supersymmetric particles in final states characterized by a leptonically decaying Z boson, missing transverse momentum and jets. The analysis uses proton-proton collision data collected by the ATLAS detector at a center-of-mass energy sqrt(s) = 13 TeV corresponding to a total integrated luminosity of 3.2 fb-1. An excess of events above the Standard Model expectation, with a significance of 2.2 standard deviations, is observed. The result is interpreted in the context of a simplified model where a Z boson is produced in the cascade decay of a gluino.
