Search for Semiboosted Higgs Pair Production From Vector Boson Fusion in the Single Lepton bbW⁺W⁻ Final State Using the ATLAS Detector — •Stefan Brückner, Lars Linden, Valerio d’Amico, Celine Stauch, Patrick Rudolph Schumacher, and Otmar Biebel — LMU Munich

The discovery of the Higgs boson solved one of the biggest problems in the standard model, the generation of particle masses. However, one property that is still not well known is the quartic coupling of a Higgs boson pair to a pair of electroweak gauge bosons. A process involving this coupling is the Di-Higgs production via vector boson fusion(VBF), which is the second most common production mode at LHC. The analysis in this talk focuses on events in the bbW⁺W⁻ final state with a single lepton, using a semiboosted approach. In this semiboosted scenario, one of the two objects, either the H→ bb or the W boson, which decays hadronically, is represented by a large radius jet. Some results of the general kinematics of the process and the event selection strategy for the semiboosted approach will be presented in the talk.
