After the discovery of the Higgs boson by the ATLAS and CMS experiments at the Large Hadron Collider, one of the major challenges in high energy physics is to confirm the form of the Higgs potential energy term in the Lagrangian of the Standard Model of fundamental particles and interactions and test the universality of the Higgs self-coupling parameter λ. This is done by observing and measuring a significant excess of events with two Higgs bosons in the final state above the background. In Oslo we focus on applying cutting-edge machine learning to final states where one of the Higgs bosons decays to two photons and the second boson decays via pairs of τ leptons or W or Z bosons to various combinations of leptons.
