title: "Table 19" 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: Expected (dashed black lines) and observed (solid black lines) 95% CL upper limits on the cross-section of resonant $HH$ production in the spin-0 signal models. The $\pm 1 \sigma$ and $\pm 2 \sigma$ uncertainty ranges for the expected limits (colored bands) are shown. Expected limits using each of the resolved and boosted channels individually (dashed colored lines) are shown. The nominal $H\rightarrow b\bar{b}$ branching ratio is taken as 0.582.
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.

title: "Figure 6 (upper left) u4m[Z120]" of "Study of quark and gluon jet substructure in Z+jet and dijet events from pp collisions"

description: Particle-level distributions of ungroomed AK4 multiplicity in 120 &lt; PT &lt; 150 GeV in the Z+jet region.
description: Measurements of jet substructure describing the composition of quark- and gluon-initiated jets are presented. Proton-proton (pp) collision data at sqrt(s)=13 TeV collected with the CMS detector are used, corresponding to an integrated luminosity of 35.9/fb. Generalized angularities are measured that characterize the jet substructure and distinguish quark- and gluon-initiated jets. These observables are sensitive to the distributions of transverse momenta and angular distances within a jet. The analysis is performed using a data sample of dijet events enriched in gluon-initiated jets, and, for the first time, a Z+jet event sample enriched in quark-initiated jets. The observables are measured in bins of jet transverse momentum, and as a function of the jet radius parameter. Each measurement is repeated applying a "soft drop" grooming procedure that removes soft and large angle radiation from the jet.For easier navigation, figures are named with a code with each letter/number representing in the following order: ungroomed/groomed, AK4/AK8, charged, multiplicity/pTD2/thrust/width/LHA, [central dijet/forward dijet/Z+jet, PT].

title: "Table 20" 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: Expected (dashed black lines) and observed (solid black lines) 95% CL upper limits on the cross-section of resonant $HH$ production in the spin-2 signal models. The $\pm 1 \sigma$ and $\pm 2 \sigma$ uncertainty ranges for the expected limits (colored bands) are shown. Expected limits using each of the resolved and boosted channels individually (dashed colored lines) are shown. The theoretical prediction for the bulk RS model with $k/\bar{M}_{\text{Pl}} = 1$ (solid red line) is shown; the decrease below 350 GeV is due to a sharp reduction in the $G^{*}_{\text{KK}} \rightarrow HH$ branching ratio. The nominal $H\rightarrow b\bar{b}$ branching ratio is taken as 0.582.
