abstract = {Constraints on the Higgs boson self-coupling are set by
combining double-Higgs boson analyses in the
$b\bar{b}b\bar{b}$, $b\bar{b}\tau^+\tau^-$ and $b\bar{b}
\gamma \gamma$ decay channels with single-Higgs boson
analyses targeting the $\gamma \gamma$, $ZZ^*$, $WW^*$,
$\tau^+ \tau^-$ and $b\bar{b}$ decay channels. The data used
in these analyses were recorded by the ATLAS detector at the
LHC in proton$-$proton collisions at $\sqrt{s}=13$ TeV and
correspond to an integrated luminosity of 126$-$139
fb$^{-1}$. The combination of the double-Higgs analyses sets
an upper limit of $\mu_{HH} < 2.4$ at 95\% confidence level
on the double-Higgs production cross-section normalised to
its Standard Model prediction. Combining the single-Higgs
and double-Higgs analyses, with the assumption that new
physics affects only the Higgs boson self-coupling
($\lambda_{HHH}$), values outside the interval $-0.4<
\kappa_{\lambda}=(\lambda_{HHH}/\lambda_{HHH}^{\textrm{SM}})<
6.3$ are excluded at 95\% confidence level. The combined
single-Higgs and double-Higgs analyses provide results with
fewer assumptions, by adding in the fit more coupling
modifiers introduced to account for the Higgs boson
interactions with the other Standard Model particles.},
