Extended Data Fig. 9: Constrains on Higgs boson self-interaction and quartic coupling.
From: A portrait of the Higgs boson by the CMS experiment ten years after the discovery
(left) Constraints on κλ and κ2V from the production of Higgs boson pairs. (right) Constraint on the Higgs boson self-coupling modifier κλ from single and pair production of Higgs boson(s).
