Search for di-Higgs Production with the CMS Experiment using the full Run 2 Dataset — •Marcel Rieger, Peter Schleper, and Tobias Kramer — Institut für Experimentalphysik, Universität Hamburg

After the discovery of the Higgs boson and measurements of its couplings to vector bosons as well as third generation fermions, the search for processes involving more than one Higgs boson will constitute one of the main goals of the global particle physics program in the coming years. The study of trilinear self-coupling will eventually give rise to the structure of the Higgs potential and can lead to profound theoretical consequences. Thereby, di-Higgs searches can gauge our understanding of electroweak symmetry breaking and probe a variety of scenarios that reach beyond the Standard Model.

The full Run 2 collision dataset recorded by the CMS experiment is analyzed in a wide range of potential di-Higgs final states to maximize the coverage of the available phase space. This talk highlights aspects of these searches with focus on final states involving two bottom quarks and two tau leptons. Prospects of the combination of channels, as far as available, are presented and constraints on the trilinear self-coupling as well as the coupling of two Higgs and two vector bosons are reported.
