Search for non-resonant Higgs boson pair production in the lepton+jets final state of the bbWW decay mode at CMS — •Mathis Frahm, Johannes Haller, Alexander Paasch, and Matthias Schröder — Institut für Experimentalphysik, Universität Hamburg

The Higgs boson self-coupling is an important parameter of the Standard Model (SM), since it is related to the shape of the Higgs potential. At the LHC, this parameter can be probed by measuring the Higgs boson pair production (HH) cross section. The sensitivity of current HH searches is limited by the small SM production cross-section of only 33  fb at 13   TeV. The analysis of data from Run 3 of the LHC promises a further leap in sensitivity.

In this talk, preparation studies towards a search for non-resonant HH production in the lepton+jets final states of the bbWW decay mode with Run 3 data of the CMS experiment are presented. They benefit from a new analysis framework that relies on the novel ’columnar analysis’ paradigm.
