Search for non-resonant di-Higgs production in the semi-leptonic bbWW decay channel at the CMS experiment — Martin Erdmann, Peter Fackeldey, Benjamin Fischer, and •Dennis Noll — III. Physikalisches Institut A - RWTH Aachen University

A measurement of the di-Higgs boson production can directly determine the trilinear Higgs coupling and probe the structure of the Higgs potential.

We present a search for Higgs boson pair production with one Higgs boson decaying into b quarks and the other Higgs boson decaying into W bosons, with one W boson decaying leptonically.

The central challenge of this analysis is a tiny signal among a large amount of background. We approach this task with a Deep Neural Network driven Physics Process Multi-Classification. It utilises a physics motivated architecture, the Lorentz-Boost Network, in conjunction with a Residual Neural Network.

We present expected limits corresponding to the data recorded at the CMS experiment in Run 2.
