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

A measurement of the Higgs boson pair 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. It includes final states with one or two leptons and resolved or boosted event topologies. The central challenge of this analysis is a tiny signal among a large amount of different backgrounds. To address this, we use physics process multiclass classification that is driven by a deep neural network.

We present results corresponding to the data recorded at the CMS experiment during Run 2.
