Search for resonant and non-resonant di-Higgs production in the decay channel γ γ WW*, with hadronically decaying W-bosons in the boosted topology. — •Kai Henßen, Jason Veatch, and Stan Lai — II. Physikalisches Institut, Georg-August-Universität Göttingen

The main reason to investigate non-resonant di-Higgs production is the determination of the trilinear Higgs coupling, which is directly related to the Higgs potential. Furthermore, several beyond-the-Standard-Model theories predict more than one Higgs boson. In particular, considering two-Higgs-doublet models, a neutral heavy scalar boson can decay into two light Higgs bosons consistent with those discovered at the LHC in 2012.

This presentation will explain the search for di-Higgs production, using √s = 13 TeV data recorded by the ATLAS experiment. The decay channel under investigation is the one in which one light Higgs boson decays into two photons and the other into two W bosons, which in turn decay hadronically. For heavy Higgs bosons, the boosted topology is considered, where all quarks from the W bosons are reconstructed as a single large radius jet.
