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

KOTO Collaboration, J. K. Ahn, M. Farriagton +47

We performed a search for the $K_{L} \to π^{0} ν ν ˉ$ decay using the data taken in 2021 at the J-PARC KOTO experiment. With newly installed counters and new analysis method, the ex…

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…

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…
