Search for supersymmetry in events with four or more leptons in $\sqrt{s}=13\,{\rm TeV}$ pp collisions using $13.3\,{\rm fb}^{−1}$ of ATLAS data.

Results from a search for supersymmetry in events with four or more leptons including electrons and muons are presented. The analysis uses a data sample corresponding to $13.3\,{\rm fb}^{−1}$ of proton--proton collisions delivered by the Large Hadron Collider at $\sqrt{s}=13\,{\rm TeV}$ and recorded by the ATLAS detector. No significant deviations are observed in data from Standard Model predictions and results are used to set upper limits on the event yields from processes beyond the Standard Model. Exclusion limits at the 95% confidence level are placed in a simplified model of chargino production with indirect RPV decays,
