title: "Table 3" of "Search for resonant pair production of Higgs bosons in the $b\bar{b}b\bar{b}$ final state using $pp$ collisions at $\sqrt{s}$ = 13 TeV with the ATLAS detector"

description: Corrected $m(HH)$ distribution in the resolved $4b$ validation region (dots), compared with the reweighted distribution in $2b$ validation region (teal histogram). The error bars on the $4b$ points represent the Poisson uncertainties corresponding to their event yields. The final bin includes overflow. The background uncertainty (gray band) is computed by adding all individual components in quadrature. The bottom panel shows the difference between the $4b$ and reweighted $2b$ distributions, relative to the $2b$ distribution.
description: A search for resonant Higgs boson pair production in the $b\bar{b}b\bar{b}$ final state is presented. The analysis uses 126-139 fb$^{-1}$ of $pp$ collision data at $\sqrt{s}$ = 13 TeV collected with the ATLAS detector at the Large Hadron Collider. The analysis is divided into two channels, targeting Higgs boson decays which are reconstructed as pairs of small-radius jets or as individual large-radius jets. Spin-0 and spin-2 benchmark signal models are considered, both of which correspond to resonant $HH$ production via gluon-gluon fusion. The data are consistent with Standard Model predictions. Upper limits are set on the production cross-section times branching ratio to Higgs boson pairs of a new resonance in the mass range from 251 GeV to 5 TeV.
The resolved channel selects four anti-$k_T$ with R = 0.4 central jets ($p_T &gt; 40$ GeV, $|\eta| &lt; 2.5$ and passing a pile-up supression cut). The signal region is defined by four central jets consistent with jets from b-quarks (b-jets) according to the DL1r b-tagging algorithm; these jets are paired into two Higgs candidates and these Higgs candidates masses are required to be consistent with the Higgs boson mass. Additional kinematic cuts are applied to reduce multijets and $t\bar{t}$ backgrounds. A similar selection is performed for the $2b$ region, but requiring two central jets to be b-tagged; this region is used for the data-driven background modeling.
The boosted channel requires events to fail the resolved selection. Then, it requires two anti-$k_T$ with R = 1.0 jets ($p_T &gt; 250$ GeV and $|\eta| &lt; 2.0$). Events are classified according to how many variable-radius track jets are reconstructed within these large-R jets, and how many of those track jets are b-tagged with the DL1r algorithm. Signal, validation and control regions are defined according to how consistent the large-R jets masses are with respect to the Higgs boson mass.

description: Corrected $m(HH)$ distribution in the resolved $4b$ signal region (dots), after the fit under the background-only hypothesis. The error bars on the $4b$ points represent the Poisson uncertainties corresponding to their event yields. The background model (teal histogram) is shown with its total post-fit uncertainty (gray band). The final bin includes overflow. Representative spin-0 signal hypotheses (dashed, dotted, and dashed-dotted lines) are overlaid, normalized to the overall expected limits on their cross-sections. The bottom panel shows the difference between the $4b$ distribution and the background model, relative to the background model. No significant excess of data relative to the SM background is observed.

description: Cumulative signal acceptance times efficiency as a function of the resonance mass for various selection steps in the boosted channel. The efficiencies of the three b-tag categories are shown for the spin-0 scenario; this efficiency is obtained after the other selection steps including the SR definition. The signal efficiency in the 4b region has a maximum around 1.5 TeV. Above that value the track-jets start to merge together, and for the highest resonance masses the 2b category becomes the most efficient.

The error bars on the data points represent the Poisson uncertainties corresponding to their event yields.

Representative spin-2 signal hypotheses (dashed and dashed-dotted lines) are overlaid, normalized to the overall expected limits on their cross-sections.
