The search regions are separated by event topology and unsupervised machine learning is used to identify anomalous events in the full 140 fb$^{-1}$ of proton-proton collision data collected with the ATLAS detector during Run 2. No significant excess above the Standard Model background expectation is observed. Model-agnostic limits are presented in each topology, along with limits on several benchmark models including vector-like leptons, wino-like charginos and neutralinos, or smuons. Limits are set on the flavourful vector-like lepton model for the first time.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.167089.v1/t1","@type":"Dataset","description":"Comparison between data and the background prediction for the (a) mT(4&#8467;, ETmiss), (b) mhigh(3&#8467;), (c) m(Z), (d) ETmiss, (e) pT(Z),...","name":"Figure 4a"},{"@id":"https://doi.org/10.17182/hepdata.167089.v1/t2","@type":"Dataset","description":"Comparison between data and the background prediction for the (a) mT(4&#8467;, ETmiss), (b) mhigh(3&#8467;), (c) m(Z), (d) ETmiss, (e) pT(Z),...","name":"Figure 4b"},{"@id":"https://doi.org/10.17182/hepdata.167089.v1/t3","@type":"Dataset","description":"Comparison between data and the background prediction for the (a) mT(4&#8467;, ETmiss), (b) mhigh(3&#8467;), (c) m(Z), (d) ETmiss, (e) pT(Z),...","name":"Figure 4c"},{"@id":"https://doi.org/10.17182/hepdata.167089.v1/t4","@type":"Dataset","description":"Comparison between data and the background prediction for the (a) mT(4&#8467;, ETmiss), (b) mhigh(3&#8467;), (c) m(Z), (d) ETmiss, (e) pT(Z),...","name":"Figure 4d"},{"@id":"https://doi.org/10.17182/hepdata.167089.v1/t5","@type":"Dataset","description":"Comparison between data and the background prediction for the (a) mT(4&#8467;, ETmiss), (b) mhigh(3&#8467;), (c) m(Z), (d) ETmiss, (e) pT(Z),...","name":"Figure 4e"},{"@id":"https://doi.org/10.17182/hepdata.167089.v1/t6","@type":"Dataset","description":"Comparison between data and the background prediction for the (a) mT(4&#8467;, ETmiss), (b) mhigh(3&#8467;), (c) m(Z), (d) ETmiss, (e) pT(Z),...","name":"Figure 4f"},{"@id":"https://doi.org/10.17182/hepdata.167089.v1/t7","@type":"Dataset","description":"Comparison between data and the background prediction for the (a) Njets, (b) ETmiss, (c) m(3&#8467;), and (d) HTlep distribution in...","name":"Figure 5a"},{"@id":"https://doi.org/10.17182/hepdata.167089.v1/t8","@type":"Dataset","description":"Comparison between data and the background prediction for the (a) Njets, (b) ETmiss, (c) m(3&#8467;), and (d) HTlep distribution in...","name":"Figure 5b"},{"@id":"https://doi.org/10.17182/hepdata.167089.v1/t9","@type":"Dataset","description":"Comparison between data and the background prediction for the (a) Njets, (b) ETmiss, (c) m(3&#8467;), and (d) HTlep distribution in...","name":"Figure 5c"},{"@id":"https://doi.org/10.17182/hepdata.167089.v1/t10","@type":"Dataset","description":"Comparison between data and the background prediction for the (a) Njets, (b) ETmiss, (c) m(3&#8467;), and (d) HTlep distribution in...","name":"Figure 5d"},{"@id":"https://doi.org/10.17182/hepdata.167089.v1/t11","@type":"Dataset","description":"Comparison between data and the background prediction for the discovery regions included in the model-independent fit, after a background-only fit...","name":"Figure 6"},{"@id":"https://doi.org/10.17182/hepdata.167089.v1/t12","@type":"Dataset","description":"Observed and expected excluded visible cross section limits, &sigma;vis for the model-independent regions.
