title: "Figure 9" of "Combination of searches for nonresonant Higgs boson pair production in proton-proton collisions at $\sqrt{s}$= 13 TeV"

description: The 95% CL upper limits on the inclusive signal strength $ r = \sigma_{HH} /\sigma_{HH} ^\text{SM} $ for each channel and their combination. The inner (green) band and the outer (yellow) band indicate the 68 and 95% CL intervals, respectively, under the background-only hypothesis. The $ b\overline{b}b\overline{b} $ and $ b\overline{b}WW $ contributions have been combined in order to simplify the presentation of results.
description: This note presents a comprehensive overview and statistical combination of searches for the nonresonant production of Higgs boson pairs (HH) using data from proton-proton collisions collected by the CMS experiment at the LHC from 2016 to 2018 at a centre-of-mass energy of 13 TeV, corresponding to a total integrated luminosity of 138 fb$ ^{-1} $. Upper limits at $95\%$ confidence level are set on the rate of the HH production. The observed (expected) upper limit on the inclusive production cross section relative to the standard model expectation is found to be 3.5 (2.5). Assuming all other Higgs boson couplings are equal to their values in the standard model, we exclude HH production at $95\%$ confidence level for values of the Higgs boson trilinear self-coupling modifier $ \kappa_{\lambda} $ outside the range between $-$1.39 and 7.02. Similarly, for the coupling modifier $ \kappa_{2\mathrm{V}} $ affecting the interaction between two vector bosons and two Higgs bosons, we exclude HH production for values outside the range between 0.62 and 1.42. This work also studies HH production in new physics scenarios, using the Higgs effective field theory parametrisation. An extrapolation of the results to the integrated luminosity expected after the high-luminosity upgrade of the LHC is also presented.

title: "Figure 10" of "Combination of searches for nonresonant Higgs boson pair production in proton-proton collisions at $\sqrt{s}$= 13 TeV"

description: The 95$\%$ CL upper limits on the VBF signal strength $r_{VBF HH} = \sigma_{VBF HH}/\sigma_{VBF HH}^{SM}$ for each channel and their combination. The inner (green) band and the outer (yellow) band indicate the 68 and 95$\%$ CL intervals, respectively, under the background-only hypothesis. Not all of the eight channels are used to extract the combined VBF limit. The contributing channels are indicated in the figure. The b\overline{b}b\overline{b} $ and $ b\overline{b}WW $ contributions have been combined in order to simplify the presentation of results.

title: "Figure 11_a" of "Combination of searches for nonresonant Higgs boson pair production in proton-proton collisions at $\sqrt{s}$= 13 TeV"

description: The 95$\%$ CL upper limits on the inclusive HH cross section as a function of $\kappa_\lambda$. All other couplings are set to the values predicted by the SM. The theoretical uncertainties in the HH GGF and VBF signal cross sections are not considered because here we directly constrain the measured cross section.The inner (green) band and the outer (yellow) band indicate the 68 and 95$\%$ CL intervals, respectively, under the background-only hypothesis. The star shows the limit at the SM value for $\kappa_\lambda$.
