title: "Table 8" of "Search for direct top squark pair production in events with a Higgs or $Z$ boson, and missing transverse momentum in $\sqrt{s}=13$ TeV $pp$ collisions with the ATLAS detector"

description: Summary of the main systematic uncertainties and their impact (in %) on the total SM background prediction in each of the signal regions studied. The total systematic uncertainty can be different from the sum in quadrature of individual sources due to the correlations between them resulting from the fit to the data. The quoted theoretical uncertainties include modelling and cross-section uncertainties.
description: A search for direct top squark pair production resulting in events with either a same-flavour opposite-sign dilepton pair with invariant mass compatible with a $Z$ boson or a pair of jets compatible with a Standard Model (SM) Higgs boson ($h$) is presented. Requirements on additional leptons, jets, jets identified as originating from b-quarks, and missing transverse momentum are imposed to target the other decay products of the top squark pair. The analysis is performed using proton-proton collision data at sqrt{s} = 13 TeV collected with the ATLAS detector at the LHC in 2015-2016, corresponding to an integrated luminosity of 36.1 fb$^{−1}$. No excess is observed in the data with respect to the expected SM predictions. The results are interpreted in two sets of models. In the first set, direct production of pairs of lighter top squarks ($\tilde{t}_1$) with long decay chains involving $Z$ or Higgs bosons is considered. The second set includes direct pair production of the heavier top squark pairs ($\tilde{t}_2$) decaying via $\tilde{t}_2 \rightarrow Z \tilde{t}_1$ or $\tilde{t}_2 \rightarrow h \tilde{t}_1$. The results exclude at 95% confidence level $\tilde{t}_2$ and $\tilde{t}_1$ masses up to about 800 GeV, extending the exclusion region of supersymmetric parameter space covered by previous LHC searches.

title: "Table 9 Up" of "Search for direct top squark pair production in events with a Higgs or $Z$ boson, and missing transverse momentum in $\sqrt{s}=13$ TeV $pp$ collisions with the ATLAS detector"

description: Observed and expected numbers of events the three 3$\ell$1$b$ Signal regions. The nominal predictions from MC simulation are given for comparison for those backgrounds, $t\bar{t} Z$, multi-boson that are normalised to data in dedicated control regions. For SR$^{3\ell 1b}_A$, SR$^{3\ell 1b}_B$ and SR$^{3\ell 1b}_C$, the "Others" category contains the contributions from $t\bar{t} h$, $t\bar{t} WW$, $t\bar{t} t$, $t\bar{t} t\bar{t}$, $Wh$, and $Zh$ production. Combined statistical and systematic uncertainties are given. Signal model-independent 95% CL upper limits on the visible BSM cross-section ($\sigma_{\mathrm{vis}}$), the visible number of signal events ($S^{95}_{\rm obs}$), the number of signal events ($S^{95}_{\rm exp}$) given the expected number of background events (and $\pm1\sigma$ variations of the expected background), and the discovery $p$-value ($p(s = 0)$), all calculated with pseudo-experiments, are also shown for each signal region.
