Combination of searches for Higgs boson pairs in pp collisions at √s = 13 TeV with the ATLAS detector
Original language description
This letter presents a combination of searches for Higgs boson pair production using up to 36.1 fb−1^{-1}−1 of proton-proton collision data at a centre-of-mass energy s=13sqrt{s} = 13s =13 TeV recorded with the ATLAS detector at the LHC. The combination is performed using six analyses searching for Higgs boson pairs decaying into the bbbb, bbWW, bbττ au auττ, WWWW, bbγγgamma gammaγγ and WWγγgammagammaγγ 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 (κλkappa_{lambda}κλ) of the Higgs boson self-coupling to its Standard Model value. This ratio is constrained at 95% confidence level to −5.0<κλ<12.0-5.0 < kappa_{lambda} <12.0−5.0<κλ<12.0.n
