Search for non-resonant di-Higgs production in the decay channel bbWW with one leptonically decaying W boson with 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 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 one decaying into W bosons, with one W boson decaying leptonically. The search works in different kinematic regions (resolved or boosted Higgs decays) and on different flavours of the final state lepton (electron or muon).

The core of the analysis is a Neural Network driven Physics Process Multi-classification using a specialised physics motivated architecture, the Lorentz-Boost Network (LBN), in conjunction with a Residual Neural Network.

Expected limits, based on simulations corresponding to the Full Run 2 dataset, are presented.
