Towards Improving the Limits on Higgs Self-Interaction in the HH to bbWW* Channel at CMS

The discovery of the Higgs boson in 2012 by ATLAS and CMS marked the completion of the Standard Model (SM) of particle physics. However, the SM still makes some predictions that have yet to be tested. Once such prediction is that the Higgs boson should self-interact, but this coupling has not yet been observed. This self-interaction predicts HH production at a challengingly small rate. Here, we present our improvements to the Higgs self-interaction measurement in the HH to bbWW* decay channel for Run 3 data at CMS. This talk focuses on the final state requiring one lepton and at least one resolved b-tagged jet. Improvements to be presented include new triggers, which capture events where the HH signal is better separated from background. We also present evolving Machine Learning (ML) techniques including multi-classification Deep Neural Networks (DNN). Projections to a full Run 3 analysis will be made.
