Abstract (data abstract)

A measurment is presented for four-top-quark production using an integrated luminosity of 140 fb$^{-1}$ of proton--proton collision data at a centre-of-mass energy of 13 TeV collected by the ATLAS detector at the LHC. Events are selected if they contain a same-sign lepton pair or at least three leptons (electrons or muons). Jet multiplicity, jet flavour and event kinematics are used to separate signal from the background through a multivariate discriminant, and dedicated control regions are used to constrain the dominant backgrounds. The four-top-quark production cross section is measured to be $22.5^{+6.6}_{-5.5}$ fb. This corresponds to an observed (expected) significance with respect to the background-only hypothesis of 6.1 (4.3) standard deviations and provides evidence for this process.
