Identification of Collinear Photons in the Context of a search for anomalous Higgs Boson DecaysBernard Brickwedde, Peter Krämer, •Marten Mildeberger, Kristof Schmieden, Matthias Schott, and Olivera Vujinovic — Johannes Gutenberg Universität Mainz

New physics models that predict couplings of axion-like-particles (ALPs) to the Higgs boson could explain the famous discrepancy between experimental value and measurement of the muon anomalous magnetic moment (g−2)µ. These models assume an ALPs decay into highly collinear photons. Hence special photon reconstruction algorithms have to be developed in order to distinguish Haa → γγγγ from normal H→ γγ signatures. In this talk, the performance of a neural network based approach for the photon identification and reconstruction will be presented.
