Search for non-resonant Higgs boson pair production in dilep- ton final states of the bbWW decay mode at CMS — Matteo Bonanomi, Mathis Frahm, Johannes Haller, Viacheslav Kosterin, •Lara Markus, Janek Möls, Alexander Paasch, and Matthias Schröder — Insitut 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 this talk, studies towards a search are presented 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 simulated proton-proton collision data at 13 TeV center-of-mass energy at the CMS experiment. The analysis is implemented in a columnar-based framework 'columnflow'.
