title: "High-mass $\text{Y}\to\gamma\gamma$ limits ($m_\text{X}$ stacks)" of "Search for the nonresonant and resonant production of a Higgs boson in association with an additional scalar boson in the $γγττ$ final state in proton-proton collisions at $\sqrt{s}$ = 13 TeV"

description: Observed and expected 95% CL upper limits on the cross section for the resonant production of a new scalar particle $\mathrm{X}$ which decays to a SM Higgs boson and a new scalar particle $\mathrm{Y}$, multiplied by the $\mathrm{Y} \to \gamma\gamma$ branching fraction, $\sigma(\mathrm{pp} \to \mathrm{X} \to \mathrm{YH})B(\mathrm{Y} \to \gamma\gamma)$. The limits are shown for different values of $m_\mathrm{Y}$ in the range 125-800 GeV and at particular values of $m_\mathrm{X}$ in the range 300-1000 GeV.
description: The results of a search for the production of two scalar bosons in final states with two photons and two tau leptons are presented. The search considers both nonresonant production of a Higgs boson pair, $\mathrm{HH}$, and resonant production via a new boson $\mathrm{X}$ which decays either to $\mathrm{HH}$ or to $\mathrm{H}$ and a new scalar $\mathrm{Y}$. The analysis uses up to 138 fb$^{-1}$ of proton-proton collision data, recorded between 2016 and 2018 by the CMS experiment at the LHC at a center-of-mass energy of 13 TeV. No evidence for signal is found in the data. For the nonresonant production, the observed (expected) upper limit at 95% confidence level (CL) on the $\mathrm{HH}$ production cross section is set at 930 (740) fb, corresponding to 33 (26) times the standard model prediction. At 95% CL, $\mathrm{HH}$ production is observed (expected) to be excluded for values of $\kappa_\lambda$ outside the range between -12 (-9.4) and 17 (15). Observed (expected) upper limits at 95% CL for the $\mathrm{X} \to \mathrm{HH}$ cross section are found to be within 160 to 2200 (200 to 1800) fb, depending on the mass of $\mathrm{X}$. In the $\mathrm{X} \to \mathrm{YH}$ production scenario, the observed (expected) upper limits vary between 0.059 -1.2 fb (0.87 -0.68 fb) for the $\mathrm{X} \to \mathrm{Y}(\to\tau\tau)\mathrm{H}(\to\gamma\gamma)$ search. For the $\mathrm{X} \to \mathrm{Y}(\to\gamma\gamma)\mathrm{H}(\to\tau\tau)$ search the observed (expected) upper limits vary between 0.69 -15 fb (0.73 -8.3 fb) in the low $\mathrm{Y}$ mass search, tightening constraints on the NMSSM, and between 0.64 -10 fb (0.70 -7.6 fb) in the high $\mathrm{Y}$ mass search.

title: "Figure 2" of "Search for dark matter produced in association with a dark Higgs boson in the $b\bar{b}$ final state using $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector"

description: Data and predicted SM background yields after a simultaneous background-only fit to each resolved (Res.) and merged (Mer.) SR and CR $E_T^{\text{miss}}$ category.
description: A search is performed for dark matter particles produced in association with a resonantly produced pair of b-quarks with $30&lt; m_{bb}&lt;150$ GeV using 140 $fb^{-1}$ of proton-proton collisions at a center-of-mass energy of 13 TeV recorded by the ATLAS detector at the LHC. This signature is expected in extensions of the Standard Model predicting the production of dark matter particles, in particular those containing a dark Higgs boson s that decays into $b\bar{b}$. The highly boosted s $\rightarrow b\bar{b}$ topology is reconstructed using jet reclustering and a new identification algorithm. This search places stringent constraints across regions of the dark Higgs model parameter space that satisfy the observed relic density, excluding dark Higgs bosons with masses between 30 and 150 GeV in benchmark scenarios with Z' mediator masses up to 4.8 TeV at 95% confidence level.
