Search for supersymmetry at 13 TeV in final states with two same-sign leptons or at least three leptons and jets using pp collisions recorded with the ATLAS detector

A search for strongly produced supersymmetric particles decaying into final states with multiple energetic jets and either two isolated leptons (e or μ) with the same electric charge or at least three isolated leptons will be presented. To extend its sensitivity, the search uses jets originating from b-quarks, missing transverse momentum, and other observables. The analysis uses proton-proton collision data at sqrt(s) = 13 TeV recorded with the ATLAS detector at the LHC. Results will be interpreted in the framework of simplified models featuring gluino and squark production.
