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…

New results on the search for rare kaon events with the KOTO detector

Brian Beckford

The KOTO experiment was designed to observe and study the K $_{L}^{0} \to$ $π^{0} ν ν ˉ$ decay at J-PARC. The Standard Model (SM) prediction for the process is (3.0 $\pm$ 0.…

Present status of the search for the K $_{L}^{0} \to π^{0} ν ν ˉ$ decay with the KOTO detector at J-PARC

Brian Beckford

We have performed a search for the K $_{L}^{0} \to π^{0} ν ν ˉ$ decay with the KOTO detector at J-PARC. The KOTO detector was designed to observe the decay and measure its b…
