Search for non-resonant Higgs boson pair production in dilepton final states of the bbWW decay mode at CMS — •Lara Markus, Matteo Bonanomi, Mathis Frahm, Johannes Haller, and Matthias Schröder — Institut für Experimentalphysik, Universität Hamburg

The trilinear coupling of the Higgs boson is related to the shape of the Higgs potential, which makes it a crucial parameter of the Standard Model. The shape can be directly probed by measuring the cross section of Higgs boson pair production in pp collisions at the LHC.
This talk presents a search for non-resonant pair production of Higgs bosons decaying into a b quark anti-quark pair and two W bosons, with subsequent decays of the W bosons into leptons and neutrinos. The analysis strategy is developed using Run 3 data of the CMS experiment, with a corresponding center-of-mass energy of at 13.6 TeV. The analysis is implemented in a columnar-based framework ‘columnflow’.

Keywords: Higgs self-coupling; Higgs boson pairs; bbWW decay mode
