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…

Kaon Physics: A Cornerstone for Future Discoveries

Jason Aebischer, Atakan Tugberk Akmete, Riccardo Aliberti +153

The kaon physics programme, long heralded as a cutting-edge frontier by the European Strategy for Particle Physics, continues to stand at the intersection of discovery and innovati…

Proposal of the KOTO II experiment

Jung Keun Ahn, Antonella Antonelli, Giuseppina Anzivino +79

The KOTO II experiment is proposed to measure the branching ratio of the decay $K_{L} \to π^{0} ν ν ˉ$ at J-PARC. With a beamline to extract long-lived neutral kaons at 5 degrees from a…

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 $K_{L}^{0} \to π^{0} ν ν ˉ$ decay a…

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…
