Description
The contribution will present updated constraints on Higgs self-interactions obtained by ATLAS and CMS from Run-3 data and combined Run-2 HH measurements, including their interplay with single-Higgs results, highlighting the progressive improvement in HH sensitivity achieved by both collaborations. The current status and future sensitivity to triple-Higgs production will be reviewed, together with the most recent HL-LHC projections for HH and HHH and the resulting expected precision on the Higgs self-couplings.
