"Table 3" of "Measurement of the $t\bar{t}Z$ and $t\bar{t}W$ cross sections in proton-proton collisions at $\sqrt{s}=13$ TeV with the ATLAS detector"
2019
95% confidence level (CL) contours of the measured $t\bar{t}Z$ and $t\bar{t}W$ cross sections.
"Table 1" of "Measurement of the $t\bar{t}Z$ and $t\bar{t}W$ cross sections in proton-proton collisions at $\sqrt{s}=13$ TeV with the ATLAS detector"
2019
The result of the simultaneous fit to the $t\bar{t}Z$ and $t\bar{t}W$ cross sections.
"Table 4" of "Measurement of the $t\bar{t}Z$ and $t\bar{t}W$ cross sections in proton-proton collisions at $\sqrt{s}=13$ TeV with the ATLAS detector"
2019
List of relative uncertainties in the measured cross sections of the $t\bar{t}Z$ and $t\bar{t}W$ processes from the fit, grouped in categories. All uncertainties are symmetrized. The sum in quadrature may not be equal to the total due to correlations between uncertainties introduced by the fit.
"Intermediate SR cutflow efficiencies" of "Search for dark matter produced in association with a dark Higgs boson decaying into $W^\pm W^\mp$ or $ZZ$…
2020
Cumulative efficiencies for the intermediate category for signal samples with ms=160 GeV (a), ms=235 GeV (b) and ms=310 GeV (c), each with mZ'=1 TeV. The TAR+Comb algorithm reconstructs the dark Higgs candidate from a TAR jet with mTAR>60 GeV that is supplemented by up to two additional small-R jets within ΔRcone=2.5 of the TAR jet. Here, Δ φjets1,2,3 ETmiss is the smallest azimuthal angle between the ETmiss and any of the three highest-pT (leading) small-R jets. For details see text.

2020
Cumulative efficiencies for the merged category for signal samples with ms=160 GeV (a), ms=235 GeV (b) and ms=310 GeV (c), each with mZ'=1 TeV. The dark Higgs candidate selection includes stringent jet substructure requirements and typically at most one candidate is present in signal events. Here, Δ φjets1,2,3 ETmiss is the smallest azimuthal angle between the ETmiss and any of the three highest-pT (leading) small-R jets.
"Upper limits on cross-section x BR (mZp=0.5 TeV)" of "Search for dark matter produced in association with a dark Higgs boson decaying into $W^\pm W^…
2020
Observed upper limits at 95% C.L. on σ(pp → s χχ) × B(s→ VV) for mZ'=0.5 TeV signal points. The expected limits, varied up and down by one and two standard deviations, are shown as green and yellow bands, respectively. The observed and expected limits are compared to the theoretical LO cross section for the σ(pp → s χχ) × B(s→ VV) process for mZ'=0.5 TeV, shown in dashed blue.

2020
The ratios (μ) of the 95% C.L. upper limits on the combined s→ W±W∓ and s→ ZZ cross section to simplified model expectations for the mZ'=0.5 TeV scenario, for various ms hypotheses. The observed limits (solid line) are consistent with the expectation under the SM-only hypothesis (dashed line) within uncertainties (filled band), except for a small excess for ms=160 GeV, discussed in the text.

Observed upper limits at 95% C.L. on σ(pp → s χχ) × B(s→ VV) for mZ'=1.7 TeV signal points. The expected limits, varied up and down by one and two standard deviations, are shown as green and yellow bands, respectively. The observed and expected limits are compared to the theoretical LO cross section for the σ(pp → s χχ) × B(s→ VV) process for mZ'=1.7 TeV, shown in dashed blue.
