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…

Search for $K_{L} \to π^{0} ν ν$ and $K_{L} \to π^{0} X^{0}$ Decays at the J-PARC KOTO Experiment

KOTO Collaboration, J. K. Ahn, B. Beckford +67

A search for the rare decay $K_{L} \to π^{0} ν ν$ was performed. With the data collected in 2015, corresponding to $2.2 \times 1 0^{19}$ protons on target, a single event se…

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…

Long-lived neutral-kaon flux measurement for the KOTO experiment

T. Masuda, J. K. Ahn, S. Banno +54

The KOTO ( $K^{0}$ at Tokai) experiment aims to observe the CP-violating rare decay $K_{L} \to π^{0} ν ν ˉ$ by using a long-lived neutral-kaon beam produced by the 30 GeV proton…

Study of the K0(L) --> pi0 pi0 nu nu-bar decay

E391a Collaboration, R. Ogata, S. Suzuki +67

The rare decay K0(L) --> pi0 pi0 nu nu-bar was studied with the E391a detector at the KEK 12-GeV proton synchrotron. Based on 9.4 x 10^9 K0L decays, an upper limit of 8.1 x 10^{-7}…
