title: "Table 1" of "Search for non-resonant Higgs boson pair production in the $bb\ell\nu\ell\nu$ final state with the ATLAS detector in $pp$ collisions at $\sqrt{s} = 13$ TeV"

description: Reconstruction-level analysis selection efficiency for the $HH \rightarrow bbWW^* \rightarrow bbl\nu l\nu$ signal process as a function of the truth-level $HH$ invariant mass, $m_{HH}$. Each color indicates an additional selection applied sequentially and in the order indicated in the legend with respect to the starting sample of events satisfying the analysis preselection requirements and having at least two $b$-tagged jets. In the legend, ``Trigger'' refers to enforcing the analysis' trigger requirements. For reference, overlaid in grey colour and with arbitrary normalisation is the truth level $m_{HH}$ distribution for events having only the preselection criteria applied. The total efficiency for the tightest selection that is shown (red line), which has selection requirements similar to those of the analysis' signal regions SR-SF and SR-DF, is $7.1\%$.
description: CERN-LHC. A search for non-resonant Higgs boson pair production, as predicted by the Standard Model, is presented, where one of the Higgs bosons decays via the $H\rightarrow bb$ channel and the other via one of the $H \rightarrow WW^*/ZZ^*/\tau\tau$ channels. The analysis selection requires events to have at least two $b$-tagged jets and exactly two leptons (electrons or muons) with opposite electric charge in the final state. Candidate events consistent with Higgs boson pair production are selected using a multi-class neural network discriminant. The analysis uses 139 fb$^{-1}$ of $pp$ collision data recorded at a centre-of-mass energy of 13 TeV by the ATLAS detector at the Large Hadron Collider. An observed (expected) upper limit of 1.2 ($0.9^{+0.4}_{-0.3}$) pb is set on the non-resonant Higgs boson pair production cross-section at 95% confidence level, which is equivalent to 40 ($29^{+14}_{-9}$) times the value predicted in the Standard Model.

title: "Table 2" of "Search for non-resonant Higgs boson pair production in the $bb\ell\nu\ell\nu$ final state with the ATLAS detector in $pp$ collisions at $\sqrt{s} = 13$ TeV"

description: Expected and observed $95\%$ CL limits on the cross-section of ggF non-resonant Higgs boson pair production as a function of the Higgs boson self-coupling modifier, $\kappa_{\lambda} = \lambda_{HHH} / \lambda_{HHH}^{\textit{SM}}$. The $\pm 1 \sigma$ and $\pm 2 \sigma$ variations about the expected limit, due to statistical and systematic uncertainties, are also shown. The method used for producing estimates of $HH$ production at non-SM values of $\kappa_{\lambda}$ is fully described in arXiv:1906.02025. The theory prediction curve represents the scenario where all parameters and couplings are set to their SM values except for $\kappa_{\lambda}$, also described in arXiv:1906.02025. The uncertainty band on the theory prediction indicates the theoretical uncertainty of this prediction. No additional analysis optimisation relative to that appearing in the main body of the analysis is performed to become particularly sensitive to non-SM values of $\kappa_{\lambda}$. The vertical dashed line indicates the SM scenario with $\kappa_{\lambda} = 1$.

title: "Figure 1" of "Search for dijet resonances using events with three jets in proton-proton collisions at $\sqrt{s}=$ 13 TeV"

description: Dijet mass spectrum (points) compared to a fitted parameterization of the background (solid curve), where the fit is performed in the range 290 &lt; $m_{jj}$ &lt; 1000 GeV in the background-only hypothesis. The horizontal bars show the widths of each bin in dijet mass. The dashed lines represent the dijet mass distribution from 400, 550, and 700 GeV resonance signals expected to be excluded at 95% CL by this analysis.
description: A search for a narrow resonance with a mass between 350 and 700 GeV, and decaying into a pair of jets, is performed using proton-proton collision events containing at least three jets. The data sample corresponds to an integrated luminosity of $18.3 ~\mathrm{fb}^{-1}$ recorded at $\sqrt{s}=13~\mathrm{TeV}$ with the CMS detector. Data are collected with a technique known as "data scouting", in which the events are reconstructed, selected, and recorded at a high rate in a compact form by the high-level trigger. The three-jet final state provides sensitivity to lower resonance masses than in previous searches using the data scouting technique. The spectrum of the dijet invariant mass, calculated from the two jets with the largest transverse momenta in the event, is used to search for a resonance. No significant excess over a smoothly falling background is found. Limits at 95% confidence level are set on the production cross section of a narrow dijet resonance. The corresponding upper limits on the coupling of a narrow vector resonance interacting only with quarks are between 0.10 and 0.15, depending on the resonance mass.These results represent the most stringent upper limits in the mass range between 350 and 450 GeV obtained with a search that is sensitive to the decay of the resonance into light-flavor quarks.

title: "Figure 2" of "Search for dijet resonances using events with three jets in proton-proton collisions at $\sqrt{s}=$ 13 TeV"

description: Upper limits at 95% CL on the product of the cross section, branching fraction, and acceptance as a function of resonance mass for a narrow vector resonance decaying into a pair of quark jets. The acceptance is calculated for the analysis selection, namely three wide jets with $p_{\mathrm{T}}$ &gt; 72 GeV and |$\eta$| &lt; 2.5, and |$\eta_{1}$ − $\eta_{2}$| &lt; 1.1. The observed limits (solid curve), expected limits (dashed curve) and their variation at the 1 and 2 standard deviation levels (shaded bands) are shown. The dashed-dotted curve shows the expected cross section times acceptance for a DM mediator.

title: "Figure 3" of "Search for dijet resonances using events with three jets in proton-proton collisions at $\sqrt{s}=$ 13 TeV"

description: Figure 3: Upper limits at 95% CL on the universal quark coupling $g'_{\mathrm{q}}$ , as a function of resonance mass, for a narrow vector resonance that only couples to quarks. The observed limits (solid curve), expected limits (dashed curve) and their variation at the 1 and 2 standard deviation levels (shaded bands) are shown. The dashed-dotted curve shows the coupling strength for which the cross section for dijet production in this model is the same as for a DM mediator.

title: "Table 1" of "Search for dijet resonances using events with three jets in proton-proton collisions at $\sqrt{s}=$ 13 TeV"

description: Acceptance for a vector resonance decaying into a dijet as a function of the resonance mass. The acceptance is calculated using signal simulations for the analysis selection, namely three wide jets with $p_{\mathrm{T}}$ &gt; 72 GeV and |$\eta$| &lt; 2.5, and |$\eta_{1}$ − $\eta_{2}$|&lt;1.1. The errors are dominated by the uncertainties in the parton shower modeling used in signal simulations.

title: "Additional Figure 1" of "Search for dijet resonances using events with three jets in proton-proton collisions at $\sqrt{s}=$ 13 TeV"

description: Comparison of the dijet mass distribution of the nominal selection (black), control selection without correction (red), and control selection with correction (blue) for data (solid histograms) and a simulation of a signal from a resonance with a mass of 400 GeV (dashed histograms). The correction, applied as a function of the product of the two largest jet transverse momenta in the event, is obtained as the ratio of the numbers of events passing the signal selection to those passing the control selection. For ease of readability, the dijet mass distributions of the signal have been scaled by an arbitrary factor. The bottom plot shows the relative difference between the dijet mass distributions of the data from the control and nominal selections. The yield of the uncorrected control selection for data is 95.7% of the nominal selection. The overlap between the two data selections is about 35% of the nominal selection. The yield of the uncorrected control selection for signal simulation of a 400-GeV resonance is about 50% of the nominal selection.

title: "Coupling limits (DM mediator)" of "Search for high mass dijet resonances with a new background prediction method in proton-proton collisions at $\sqrt{s} =$ 13 TeV"

description: The observed and expected 95% CL upper limits on the universal quark coupling $g_{q}$ as a function of resonance mass for a vector mediator of interactions between quarks and dark matter.
description: A search for narrow and broad resonances with masses greater than 1.8 TeV decaying to a pair of jets is presented. The search uses proton-proton collision data at$\sqrt{s} = 13~\mathrm{TeV}$ collected at the LHC, corresponding to an integrated luminosity of $137~\mathrm{fb}^{-1}$. The background arising from standard model processes is predicted with the fit method used in previous publications and with a new method. The dijet invariant mass spectrum is well described by both data-driven methods, and no significant evidence for the production of new particles is observed. Model independent upper limits are reported on the production cross sections of narrow resonances, andbroad resonances with widths up to $55\%$ of the resonance mass. Limits are presented on the masses of narrow resonances from various models: string resonances, scalardiquarks, axigluons, colorons, excited quarks, color-octet scalars, W$^{\prime}$ and Z$^{\prime}$ bosons, Randall–Sundrum gravitons, and dark matter mediators. The limits on narrow resonances are improved by 200 to 800 GeV relative to those reported in previous CMS dijet resonance searches. The limits on dark matter mediators are presented as a func-tion of the resonance mass and width, and on the associated coupling strength as a function of the mediator mass. These limits exclude at $95\%$ confidence level a darkmatter mediator with a mass of 1.8 TeV and width $1\%$ of its mass or higher, up to one with a mass of 4.8 TeV and a width $45\%$ of its mass or higher.
