The combination is performed using six analyses searching for Higgs boson pairs decaying into the bbbb, bbWW, bb$\\tau\\tau$, WWWW, bb$\\gamma\\gamma$ and WW$\\gamma\\gamma$ final states. Results are presented for non-resonant and resonant Higgs boson pair production modes. The combined observed limit at 95% confidence level on the non-resonant Higgs boson pair production cross-section is 6.9 times the predicted Standard Model cross-section. Limits are also set on the ratio ($\\kappa_{\\lambda}$) of the Higgs boson self-coupling to its Standard Model value. This ratio is constrained at 95% confidence level to -5.0$&lt;\\kappa_{\\lambda}&lt;$12.0. In addition, limits are set on the production of narrow scalar resonances and spin-2 Kaluza-Klein Randall-Sundrum gravitons. Exclusion regions are also provided in the parameter space of the habemus Minimal Supersymmetric Standard Model and the Electroweak Singlet Model.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.90521.v1/t1","@type":"Dataset","description":"Signal acceptance times efficiency as a function of &kappa;&lambda; for the $b\\bar{b}b\\bar{b}$, $b\\bar{b}\\tau^{+}\\tau^{-}$ and $b\\bar{b}\\gamma\\gamma$ analyses.
