Search for Boosted Higgs Pair Production From Vector Boson Fusion in the Single Lepton bbW⁺W⁻ Final State Using the ATLAS Detector — •Lars Linden, Valerio d’Amico, Celine Stauch, Stefanie Götz, Bao Tai Le, Tim Rexrodt, 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, even more than 10 years after its discovery, not all of its properties are well know. One of these is the quartic coupling of a Higgs boson pair to a pair of electroweak gauge bosons. A process suited to constrain this coupling is given by Di-Higgs production via vector boson fusion (VBF), the second most common production mode at LHC. This talk will present some early results of a search for VBF Di-Higgs production in the bbW⁺W⁻ final state with a single lepton, using the ATLAS run 2 and 3 datasets.
