Evidence for four-top quark production in proton-proton collisions at $ \sqrt{s} = $ 13 TeV
Phys. Lett. B 844 (2023) 138076
Abstract: The production of four top quarks ($ \mathrm{t}\bar{\mathrm{t}}\mathrm{t}\bar{\mathrm{t}} $) is studied with LHC proton-proton collision data samples collected by the CMS experiment at a center-of-mass energy of 13 TeV, and corresponding to integrated luminosities of up to 138 fb$ ^{-1} $. Events that have no leptons (all-hadronic), one lepton, or two opposite-sign leptons (where lepton refers only to prompt electrons or prompt muons) are considered. This is the first $ \mathrm{t}\bar{\mathrm{t}}\mathrm{t}\bar{\mathrm{t}} $ measurement that includes the all-hadronic final state. The observed significance of the $ \mathrm{t}\bar{\mathrm{t}}\mathrm{t}\bar{\mathrm{t}} $ signal in these final states of 3.9 standard deviations (1.5 expected) provides evidence for $ \mathrm{t}\bar{\mathrm{t}}\mathrm{t}\bar{\mathrm{t}} $ production, with a measured cross section of 36 $ ^{+12}_{-11} $ fb. Combined with earlier CMS results in other final states, the signal significance is 4.0 standard deviations (3.2 expected). The combination returns an observed cross section of 17 $ \pm $ 4 (stat) $ \pm $ 3 (syst) fb, which is consistent with the standard model prediction.

Summary
We have measured the cross section for the simultaneous production of four top quarks ($ \mathrm{t}\bar{\mathrm{t}}\mathrm{t}\bar{\mathrm{t}} $) in proton-proton collisions. The data were collected by the CMS experiment at the LHC in 2016--2018, and correspond to an integrated luminosity of up to 138 fb$ ^{-1} $ at a center-of-mass energy of 13 TeV. The all-hadronic final state has been studied for the first time in a $ \mathrm{t}\bar{\mathrm{t}}\mathrm{t}\bar{\mathrm{t}} $ production analysis, using a background estimation strategy based on a deep neural network trained using control regions in data. Final states with one lepton (electron or muon), or two opposite-sign leptons have also been analyzed. The observed and expected significances obtained from the combination of the new analyses described here are 3.9 and 1.5 standard deviations, respectively. When combined with published CMS results in other final states, the significances increase to 4.0 (observed) and 3.2 (expected) standard deviations. This is a significant improvement compared to previous CMS results and the first CMS evidence for $ \mathrm{t}\bar{\mathrm{t}}\mathrm{t}\bar{\mathrm{t}} $ production with a significance above three standard deviations.

The dashed line shows the SM prediction of the dependence of the $ \mathrm{t}\bar{\mathrm{t}}\mathrm{t}\bar{\mathrm{t}} $ cross section as a function of the Yukawa coupling, calculated at LO with MadGraph-5\_aMC@NLO 2.7.3 including electroweak diagrams [1]. The prediction is normalised to the calculation at NLO+EW in the SM that is represented by the red cross [3]. The shaded bands represent the total uncertainty from the measurement or theoretical uncertainties taken from [3].

Additional Table 5:
Summary of systematic uncertainties used as input to the simultaneous fit. Correlations are also indicated. Note ''All'' refers to all simulated samples, not including data-driven QCD+ $ \mathrm{t} \bar{\mathrm{t}} $ backgrounds in the all-hadronic channel. ''ttX'' refers to $ \mathrm{t} \bar{\mathrm{t}} $ production in association with single bosons (H, W, Z). Data-prediction shape and normalization uncertainties apply to the data-driven QCD+ $ \mathrm{t} \bar{\mathrm{t}} $ backgrounds in the all-hadronic channel that are derived in the validation region (VR) and applied in the signal region (SR) for corresponding categories. These uncertainties are correlated between top SR categories per year that use the same NN trainings.
