Telescope Array search for EeV photons

Abstract

We present updated results of the search for the ultra-high energy photons with primary energies greater than 10 EeV. The data of the Telescope Array Surface Detector collected over 11 years are used in this work. The method is based on the machine learning classifier, which is trained on both the reconstructed composition-sensitive parameters of the event and the calibrated waveform signals at each triggered station of the Surface Detector.
