title: "Figure 15_b" of "Combination of searches for nonresonant Higgs boson pair production in proton-proton collisions at $\sqrt{s}$= 13 TeV"

description: The profile likelihood ratio test statistic $-2\Delta\log(L)$ as a function of the $c_2$ coupling modifier.
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.
