Description
We report the ultra-high energy (> 1EeV) photon flux limits based on the analysis of the 9 years data from the Telescope Array Surface detector. The multivariate classifier is built upon 16 reconstructed parameters of the extensive air shower. These parameters are related to the curvature and the width of the shower front, the steepness of the lateral distribution function and the timing parameters of the waveforms sensitive to the shower muon content. A total number of 2 photon candidates found in the search which is fully compatible with the expected background. The diffuse flux limits as long as the point source flux limits for all directions in the Northern hemisphere are presented. We report the limits on ultra-high energy down-going neutrino search.
