Arely Cortes Gonzalez: HH at LHC and beyond: Review of latest results and future prospects

Monday 10 Mar 2025, 15:00 → 16:30 Europe/Madrid

The Standard Model makes a definite prediction for the Higgs boson self-coupling and thereby the shape of the Higgs potential. Experimentally, both can be probed through the production of Higgs boson pairs (HH), a rare process that is one of the milestones of Higgs physics at the LHC. In this seminar, the latest HH searches at the LHC are reported, with emphasis on the results obtained with the full LHC Run 2 dataset at 13 TeV. Non-resonant HH search results are interpreted both in terms of sensitivity to the Standard Model and as limits on the Higgs boson self-coupling and the quartic VVHH coupling. Studies based on current analyses have been carried out to understand the expected precision of these measurements at the High Luminosity LHC (HL-LHC). Prospects for di-Higgs results assuming a dataset of 3 ab-1 at the HL-LHC will also be presented.
