Description
The study of Higgs boson pair production provides direct access to the structure of the Higgs potential and is one of the key probes of electroweak symmetry breaking at the LHC. In the Standard Model, Higgs boson pairs are produced with a very small cross section, making this measurement experimentally challenging. At the same time, this process is highly sensitive to possible contributions from physics beyond the Standard Model, including modifications of the Higgs self-coupling, anomalous interactions in effective field theory interpretations, and the production of new resonances decaying into a pair of Higgs bosons.
This talk presents an overview of searches for Higgs boson pair production performed by the CMS experiment. A broad range of final states is covered, exploiting the complementary sensitivity of channels involving b quarks, photons, W and Z bosons, tau leptons, and multilepton signatures. The talk summarizes the combination of multiple final states, constraints on the Higgs boson self-coupling and effective field theory parameters, and the prospects for future improvements with larger datasets and upgraded analysis techniques.
