Deep-Learning driven Signal Extraction in the Associated VH-Production with the CMS Experiment — •Niclas Eich, Svenja Diekmann, and Martin Erdmann — RWTH Aachen

The Higgs Boson production in association with a Vector Boson known as "Higgs-Strahlung" (VH) is one of the four main production modes of the Higgs at the LHC. The VH-production can be divided into two modes, being produced by quark-annihilation and gluon-fusion for a Z boson respectively. In our analysis, we aim to measure the gluon-fusion process in the final states with the Higgs decaying to a b-quark pair and the W/Z decaying leptonically. We make use of the symmetries between the quark and gluon induced processes and deploy Deep Learning techniques to maximize the sensitivity of the measurement. Finally, we present first results towards the signal extraction using the data-taking period 2017 of the CMS experiment.
