The data used in these analyses were recorded by the ATLAS detector at the LHC in proton\u2212proton collisions at 13 TeV and correspond to an integrated luminosity of 126\u2212139 fb$^{-1}$ . The combination of the double-Higgs analyses sets an upper limit of $\\mu_{HH} < 2.4$ at 95% confidence level on the double-Higgs production cross-section normalised to its Standard Model prediction. Combining the single-Higgs and double-Higgs analyses, with the assumption that new physics affects only the Higgs boson self-coupling ($\\lambda_{HHH}$), values outside the interval $-0.4< \\kappa_\\lambda < 6.3$ are excluded at 95% confidence level. The combined single-Higgs and double-Higgs analyses provide results with fewer assumptions, by adding in the fit more coupling modifiers introduced to account for the Higgs boson interactions with the other Standard Model particles.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.135471.v1/t1","@type":"Dataset","description":"Observed and expected 95% CL upper limits on the signal strength for double-Higgs production from the bbbb, bb$\\tau\\tau$ and bb$\\gamma\\gamma$...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.135471.v1/t2","@type":"Dataset","description":"Observed and expected 95% CL exclusion limits on the production cross-sections of the combined ggF HH and VBF HH processes...","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.135471.v1/t3","@type":"Dataset","description":"Observed and expected 95% CL exclusion limits on the production cross-sections of the VBF HH process as a function of...","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.135471.v1/t4","@type":"Dataset","description":"Observed values of the test statistic (-2ln$\\Lambda$), as a function of the $\\kappa_\\lambda$ parameter for the single-Higgs and double-Higgs analyses...","name":"Table 4 (HHH obs)"},{"@id":"https://doi.org/10.17182/hepdata.135471.v1/t5","@type":"Dataset","description":"Observed values of the test statistic (-2ln$\\Lambda$), as a function of the $\\kappa_\\lambda$ parameter for the double-Higgs analyses, with all...","name":"Table 5 (diHiggs obs)"},{"@id":"https://doi.org/10.17182/hepdata.135471.v1/t6","@type":"Dataset","description":"Observed values of the test statistic (-2ln$\\Lambda$), as a function of the $\\kappa_\\lambda$ parameter for the single-Higgs analyses, with all...","name":"Table 6 (singleH obs)"},{"@id":"https://doi.org/10.17182/hepdata.135471.v1/t7","@type":"Dataset","description":"Observed values of the test statistic (-2ln$\\Lambda$), as a function of the $\\kappa_\\lambda$ parameter for the single-Higgs and double-Higgs combination...","name":"Table 7 (generic obs)"},{"@id":"https://doi.org/10.17182/hepdata.135471.v1/t8","@type":"Dataset","description":"Expected values of the test statistic (-2ln$\\Lambda$), as a function of the $\\kappa_\\lambda$ parameter for the single-Higgs and double-Higgs analyses...","name":"Table 8 (HHH exp)"},{"@id":"https://doi.org/10.17182/hepdata.135471.v1/t9","@type":"Dataset","description":"Expected values of the test statistic (-2ln$\\Lambda$), as a function of the $\\kappa_\\lambda$ parameter for the double-Higgs analyses.","name":"Table 9 (diHiggs exp)"},{"@id":"https://doi.org/10.17182/hepdata.135471.v1/t10","@type":"Dataset","description":"Expected values of the test statistic (-2ln$\\Lambda$), as a function of the $\\kappa_\\lambda$ parameter for the single-Higgs analyses, with all...","name":"Table 10 (singleH exp)"},{"@id":"https://doi.org/10.17182/hepdata.135471.v1/t11","@type":"Dataset","description":"Expected values of the test statistic (-2ln$\\Lambda$), as a function of the $\\kappa_\\lambda$ parameter for the single-Higgs and double-Higgs analyses...","name":"Table 11 (generic exp)"},{"@id":"https://doi.org/10.17182/hepdata.135471.v1/t12","@type":"Dataset","description":"Observed constraints in the $\\kappa_\\lambda$\u2013$\\kappa_t$ plane from single-Higgs and double-Higgs combination.
