Suppression of Neutron Background using Deep Neural Network and Fourier Frequency Analysis at the KOTO Experiment

Y. -C. Tung, J. Li, Y. B. Hsiung +9

We present two analysis techniques for distinguishing background events induced by neutrons from photon signal events in the search for the rare $K_L^0\to {\pi }^0\nu \bar{\nu }$ decay a…
