Event display of a candidate four-top-quark event, where two of the top quarks decay leptonically -- one with a resulting muon (red) and one with an electron (green) -- and two top quarks decay hadronically (green and yellow rectangles). The jets -- b-tagged jets -- are shown as yellow (blue) cones. Image credit: ATLAS Collaboration / CERN.
