Description

Constraints on the Higgs boson self-coupling are set by combining the single Higgs boson analyses targeting the γγ, ZZ, WW, tau+tau- and bb decay channels and the double Higgs boson analyses in the bbbb, bbtau+tau- and bbγγ decay channels, using data collected at sqrt(s)=13 TeV with the ATLAS detector at the LHC. With the assumption that new physics affects only the Higgs boson self-coupling (λ_HHH), the measured values for λ_HHH will be discussed. Results with less stringent assumptions are also provided, introducing additional coupling modifiers for the Higgs boson interactions with the other Standard Model particles.
