Searching for EeV photons with Telescope Array Surface Detector and neural networks

Telescope Array Collaboration, R. U. Abbasi, T. Abu-Zayyad +126

Ultra-high-energy photons play an important role in probing astrophysical models and beyond-Standard-Model scenarios. We report updated limits on the diffuse photon flux using Tele…
