Abstract (data abstract)
CERN-LHC, ATLAS. This result is a search for new phenomena in events with two same-charge leptons or three leptons and jets identified as originating from b-quarks in a data sample of 36.1 fb−1 of pp collisions at √s = 13 TeV recorded by the ATLAS detector at the Large Hadron Collider. No significant excess is found and limits are set on vector-like quark, four-top-quark, and same-sign top-quark pair production.
