Observed excluded region (95\% CL), shown in blue, in the $m_{\tilde{g}}$-$m_{\tilde{\chi}^0_1}$ plane for a model combining T5tttt, gluino pair production, followed by gluino decay to an on-shell top squark, together with a model for direct top squark pair production. The top squarks decay via the two-body process $\tilde{t}\rightarrow t\tilde{\chi}^0_1$. The neutralino and top squark masses are related by the constraint $m_{\tilde{t}} = m_{\tilde{\chi}^0_1} + 175$ GeV.

A summary of benchmark simplified models, the most sensitive $n_{\mathrm{jet}}$ categories, and representative values for the corresponding experimental acceptance times efficiency ($\mathcal{A}\varepsilon$), the dominant systematic uncertainties, the theoretical production cross section ($\sigma_{\mathrm{theory}}$), and the expected and observed upper limits on the production cross section, expressed in terms of the signal strength parameter ($\mu$).

Summary of the mass limits obtained for the fourteen classes of simplified models. The limits indicate the strongest observed and expected (in parentheses) mass exclusions in $\tilde{g}$, $\tilde{q}$, $\tilde{b}$, $\tilde{t}$, and $\tilde{\chi}_1^0$. The quoted values have uncertainties of $\pm 25$ and $\pm 10$ GeV for models involving the pair production of, respectively, gluinos and squarks.

Summary of a simplified binning scheme comprising $H_{\mathrm{T}}^{\mathrm{miss}}$ shapes for eight representative event topologies, defined in terms of requirements on $n_{\mathrm{jet}}$ both symmetric and asymmetric categories) and $n_{\mathrm{b}}$. For each topology, event yields are integrated over the full $H_{\mathrm{T}}$ range, $H_{\mathrm{T}} > 200$ GeV, and are categorised according to eight bins in $H_{\mathrm{T}}^{\mathrm{miss}}$ -- $130 < H_{\mathrm{T}}^{\mathrm{miss}} < 200$ GeV, six bins 100 GeV wide in the region $200 < H_{\mathrm{T}}^{\mathrm{miss}} < 800$ GeV, and an open final bin, $H_{\mathrm{T}}^{\mathrm{miss}} > 800$ GeV. This categorisation scheme leads to 64 bins that are exclusive, contiguous, and provide complete coverage of the signal region. The corresponding SM background estimates for these 64 bins are obtained using the nominal likelihood model. The $H_{\mathrm{T}}^{\mathrm{miss}}$ template for each topology is determined from simulation and the normalisation for each template is given by an aggregate of estimates from several ($n_{\mathrm{jet}}$, $n_{\mathrm{b}}$, $H_{\mathrm{T}}$) bins, defined according to the nominal binning scheme.

Observed data yields and "CR-only fit" SM background expectations using the simplified binning scheme, as a function of topology and $H_{\mathrm{T}}^{\mathrm{miss}}$. The SM backgrounds are determined from a simultaneous fit to data in the control regions. The data yields in the signal region are masked and excluded from the fit. The uncertainties include statistical as well as systematic contributions.

Expected ($\mu_{\mathrm{exp}}$) and observed ($\mu_{\mathrm{obs}}$) upper limits on the production cross section, expressed in terms of the signal strength parameter, obtained using both the nominal and simplified binning schema. Comparable values are obtained from the two schema for these benchmark SUSY models because the signal events typically populate bins at high values of $H_{\mathrm{T}}$ and $H_{\mathrm{T}}^{\mathrm{miss}}$ and so are at or near the limit of the search sensitivity. Larger differences in $\mu$ can be observed for models that populate the core of these distributions.

Exclusion regions at 95% CL in the $m_{\tilde{\chi}_1^0}$ versus $m_{\tilde{g}}$ plane for the T1tttt (upper left) and T5ttbbWW (upper right) models, with off-shell third-generation squarks, and the T5tttt (lower left) and T5ttcc (lower right) models, with on-shell third-generation squarks. For the T5ttbbWW model, $m_{\tilde{\chi}_1^\pm} = m_{\tilde{\chi}_1^0} + 5 GeV$, for the T5tttt model, $m_{\tilde{t}} - m_{\tilde{\chi}_1^0} = m_t$, and for the T5ttcc model, $m_{\tilde{t}} - m_{\tilde{\chi}_1^0} = 20 GeV$ and the decay proceeds through $\tilde{t} \to c \tilde{\chi}_1^0$. The right-hand side color scale indicates the excluded cross section values for a given point in the SUSY particle mass plane. The solid black curves represent the observed exclusion limits assuming the approximate-NNLO+NNLL cross sections (thick line), or their variations of $\pm 1$ standard deviations (s.d.) (thin lines).
