Measurement of the $t\bar{t}t\bar{t}$ production cross section in $pp$ collisions at $\sqrt{s}$=13 TeV with the ATLAS detector

The ATLAS collaboration
CERN-EP-2021-075, 2021.

Abstract (data abstract)
CERN-LHC, ATLAS. Measurements of the of four-top-quark production cross section using events with single lepton (electron or muon) or an opposite-sign lepton pair, in association with multiple jets in proton-proton collisions at a centre-of-mass energy of 13 TeV with 139 fb^-1 of data. The result is combined with the previous measurement performed by the ATLAS Collaboration in the multilepton final state.
