The Search for $K_{L} \to π^{0} π^{0} γ γ$ and $K_{L} \to π^{0} π^{0} X$ where $X \to 2 γ$ at the KOTO Experiment

J. Redeker, C. Lin, Y. W. Wah +23

We performed searches for $K_{L} \to π^{0} π^{0} X$ where $X$ may be an axion-like particle which promptly decays to two photons, and the first search for $K_{L} \to π^{0} π^{0} γ γ$ …

Search for Dark Particles in $K_{L}^{0} \to γ X$ at the KOTO Experiment

T. Wu, Y. C. Tung, Y. B. Hsiung +24

We report a search for an invisible particle $X$ in the decay $K_{L}^{0} \to γ X$ ( $X \to invisible$ ), where $X$ can be interpreted as a massless or massive dark photon. N…

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…

Study of the $K_{L} \to π^{0} ν ν$ Decay at the J-PARC KOTO Experiment

KOTO Collaboration, J. K. Ahn, B. Beckford +68

The rare decay $K_{L} \to π^{0} ν ν$ was studied with the dataset taken at the J-PARC KOTO experiment in 2016, 2017, and 2018. With a single event sensitivity of $( 7.20 \p…

A new search for the $K_{L} \to π^{0} ν ν$ and $K_{L} \to π^{0} X^{0}$ decays

J. K. Ahn, K. Y. Baek, S. Banno +87

We searched for the $C P$ -violating rare decay of neutral kaon, $K_{L} \to π^{0} ν ν$ , in data from the first 100 hours of physics running in 2013 of the J-PARC KOTO experimen…
