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…

A new measurement of electron transverse polarization in polarized nuclear beta decay

H. Kawamura, T. Akiyama, M. Hata +20

The Mott polarimetry for T -Violation (MTV) experiment tests time-reversal symmetry in polarized nuclear beta decay by measuring an electron's transverse polarization as a form of…

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…
