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…

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…
