title: "Table 15" of "Combination of searches for Higgs boson pair production in $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector"

description: Observed and expected 95&percnt; CL upper limits on the signal strength for the VBF HH production from the bb̄τ<sup>+</sup>τ<sup>-</sup>, bb̄γγ, bb̄bb̄, multilepton and bb̄ℓℓ+E<sub>T</sub><sup>miss</sup> decay channels, and their statistical combination. When deriving the limit on μ<sub>ggF</sub><sup>HH</sup> (μ<sub>VBF</sub><sup>HH</sup>), the VBF (ggF) HH production cross-section is fixed to the SM predicted value for m<sub>H</sub>=125 GeV. The expected limit, along with the ±1σ and ±2σ bands, is calculated under the assumption of no HH process and with all NPs profiled to the observed data.
description: This Letter presents results from a combination of searches for Higgs boson pair production using 126--140 fb$^{-1}$ of proton--proton collision data at $\sqrt{s}=13$ TeV recorded with the ATLAS detector. At 95% confidence level (CL), the upper limit on the production rate is 2.9 times the Standard Model (SM) prediction, with an expected limit of 2.4 assuming no Higgs boson pair production. Constraints on the Higgs boson self-coupling modifier $\kappa_{\lambda}=\lambda_{HHH}/\lambda_{HHH}^\mathrm{SM}$, and the quartic $HHVV$ coupling modifier $\kappa_{2V}=g_{HHVV}/g_{HHVV}^\mathrm{SM}$, are derived individually, fixing the other parameter to its SM value. The observed 95% CL intervals are $-1.2 &lt; \kappa_{\lambda} &lt; 7.2$ and $0.6 &lt; \kappa_{2V} &lt; 1.5$ respectively, while the expected intervals are $-1.6 &lt; \kappa_{\lambda} &lt; 7.2$ and $0.4 &lt; \kappa_{2V} &lt; 1.6$ in the SM case. Constraints obtained for several interaction parameters within Higgs effective field theory are the strongest to date, offering insights into potential deviations from SM predictions.
