Abstract
Both the ATLAS and CMS collaborations have reported a Standard Model Higgs-like excess at around mh = 125 GeV. If an SM-like Higgs particle is discovered in this particular mass range, an important additional test of the SM electroweak symmetry breaking sector is the measurement of the Higgs self-interactions. We investigate the prospects of measuring the Higgs self-coupling for mh = 125 GeV in the dominant SM decay channels in boosted and unboosted kinematical regimes. We further enhance sensitivity by considering dihiggs systems recoiling against a hard jet. This configuration exhibits a large sensitivity to the Higgs self-coupling which can be accessed in subjet-based analyses. Combining our analyses allows constraints to be set on the Higgs self-coupling at the LHC.
