Search for the Pair Production of Dark Particles $X$ with $K_{L}^{0} \to X X$ , $X \to γ γ$

C. Lin, J. K. Ahn, J. M. Choi +39

We present the first search for the pair production of dark particles $X$ via $K_{L}^{0} \to X X$ with $X$ decaying into two photons using the data collected by the KOTO experiment. No s…

First Search for the $K_{L} \to π^{0} γ$ Decay

J. K. Ahn, B. Beckford, M. Campbell +59

We report the first search for the $K_{L} \to π^{0} γ$ decay, which is forbidden by Lorentz invariance, using the data from 2016 to 2018 at the J-PARC KOTO experiment. With a single ev…

Neutron beam test of CsI crystal for dark matter search

H. Park, D. H. Choi, I. S. Hahn +20

We have studied the response of Tl-doped and Na-doped CsI crystals to nuclear recoils and $γ$ 's below 10 keV. The response of CsI crystals to nuclear recoil was studied with mono-e…
