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 $-1.2 < \\kappa_{\\lambda} < 7.2$ and $0.6 < \\kappa_{2V} < 1.5$ respectively, while the expected intervals are $-1.6 < \\kappa_{\\lambda} < 7.2$ and $0.4 < \\kappa_{2V} < 1.6$ 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.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.153612.v1/t1","@type":"Dataset","description":"Observed and expected 95% CL upper limits on the signal strength for inclusive ggF HH
