Abstract:
In the Standard Model, the ground state of the Higgs field is found at
one of the non-zero minima of the Higgs potential. In turn, this
spontaneous electroweak symmetry breaking provides a mechanism to
generate the mass of nearly all fundamental particles. The Standard
Model makes a definite prediction for the Higgs boson self-interaction
and thereby the shape of the Higgs potential. Experimentally, both can
be probed through the production of Higgs boson pairs (HH) at the LHC.
In this talk, the latest HH searches by the ATLAS and CMS collaborations
are reported, with emphasis on the results obtained with the full LHC
Run 2 dataset at 13 TeV, and their statistical combinations.
