    Search for QCD instantons at the LHC using the ATLAS Detector by Harris, YT

    Published 2023
    “…Instanton field configurations are deeply embedded in the Standard Model of particle physics, being already essential in explaining the heaviness of the $\eta'$ meson. Yet they have never been observed. The search presented here uses a Machine Learning technique based on Deep Neural Networks (DNNs) for concomitant signal discrimination and background estimation. …”
