Evidence for tt¯tt¯ production in the multilepton final state in proton–proton collisions at √s=13 TeV with the ATLAS detector
Original language description
A search is presented for four-top-quark production using an integrated luminosity of 139 fb−1^{-1}−1 of proton–proton collision data at a centre-of-mass energy of 13 TeV13~ ext {TeV}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 24−6+724^{+7}_{-6}24−6+7 fb. This corresponds to an observed (expected) significance with respect to the background-only hypothesis of 4.3 (2.4) standard deviations and provides evidence for this process.
