Constraints on the Higgs boson self-coupling from the combination of single and double Higgs boson production in proton-proton collisions at $\sqrt{s}$ = 13 TeV

CMS Collaboration

The Higgs boson (H) trilinear self-coupling, ${\lambda }_3$, is constrained via its measured properties and limits on the HH pair production using the proton-proton collision data collected…
