title: "Additional Figure A4" of "Model-independent measurement of the Higgs boson associated production with two jets and decaying to a pair of W bosons in proton-proton collisions at $\sqrt{s}$ = 13 TeV"

description: Correlation matrix for fit configuration 3
description: A model-independent measurement is presented of the differential production cross section of the Higgs boson decaying into a pair of W bosons, with a final state including two jets produced in association. In the analysis, events are selected in which the decay products of the two W bosons consist of an electron, a muon, and two neutrinos. The study is based on proton-proton collision data collected with the CMS detector from 2016 to 2018, corresponding to an integrated luminosity of $138~\mathrm{fb}^{-1}$. The production cross section is measured as a function of the difference in azimuthal angle between the two jets. The differential cross section measurements are used to constrain Higgs boson couplings within the standard model effective field theory framework.

title: "Table 1 (Weighted di-photon invariant mass distribution)" of "Study of Higgs boson pair production in the $HH \rightarrow b \overline{b} \gamma\gamma$ final state with 308 fb$^{-1}$ of data collected at $\sqrt{s} = 13$ TeV and 13.6 TeV by the ATLAS experiment"

description: Weighted di-photon invariant mass distribution summed over all categories and the two data-taking periods. The events in each category are weighted by $log(1+S_{SM}/B)$. $S_{SM}$ is the expected signal yield assuming $\mu_{HH}$=1, while B is the continuum background yield obtained from a fit to the sidebands plus the single Higgs boson background obtained from simulation, all in a ± 5 GeV window around the Higgs boson mass. The lines show the fit results for the continuum background only (light dotted), adding single Higgs boson backgrounds (black dotted) and the full fit (solid).
description: A search for Higgs boson pair production in the $b \overline{b} \gamma \gamma$ final state is performed. The proton-proton collision dataset in this analysis corresponds to an integrated luminosity of 308 fb$^{-1}$, consisting of two samples, with 140 fb$^{-1}$ at a centre-of-mass energy of 13 TeV and 168 fb$^{-1}$ at 13.6 TeV, recorded between 2015 and 2024 by the ATLAS detector at the CERN Large Hadron Collider. Compared to the result of a previous search in the same final state, in addition to the increased dataset, the analysis incorporates several methodological and technical improvements. The Higgs boson pair production cross section divided by the Standard Model prediction is found to be $\mu_{HH} = 0.9^{+1.4}_{-1.1}$ ($\mu_{HH} = 1^{+1.3}_{-1.0}$ expected), which translates into a 95% confidence-level upper limit of $\mu_{HH}&lt;3.8$. At the same confidence level the Higgs self-coupling modifier is constrained to be in the range $-1.7 &lt; \kappa_\lambda &lt; 6.6$ ($-1.8 &lt; \kappa_\lambda &lt; 6.9$ expected).
