Search for three body pion decays $π^{+} \to l^{+} ν X$

A. Aguilar-Arevalo, M. Aoki, M. Blecher +21

The three body pion decays $π^{+} \to l^{+} ν X (l = e, μ)$ , where $X$ is a weakly interacting neutral boson, were searched for using the full data set from the PIENU experiment. An…

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 the rare decays $π^{+} \to μ^{+} ν_{μ} ν ν ˉ$ and $π^{+} \to e^{+} ν_{e} ν ν ˉ$

A. Aguilar-Arevalo, M. Aoki, M. Blecher +23

The rare pion decays $π^{+} \to μ^{+} ν_{μ} ν ν ˉ$ and $π^{+} \to e^{+} ν_{e} ν ν ˉ$ are allowed in the Standard Model but highly suppressed. These decays were searched for usi…

Improved search for two body muon decay $μ^{+} \to e^{+} X_{H}$

A. Aguilar-Arevalo, M. Aoki, M. Blecher +21

Charged lepton flavor violating muon decay $μ^{+} \to e^{+} X_{H}$ , where $X_{H}$ is a massive neutral boson, was sought by searching for extra peaks in the muon decay $μ^+{\rightar…

Search for Heavy Neutrinos in $π \to μν$ Decay

A. Aguilar-Arevalo, M. Aoki, M. Blecher +21

Heavy neutrinos were sought in pion decays $π^{+} \to μ^{+} ν$ by examining the observed muon energy spectrum for extra peaks in addition to the expected peak for a massless ne…
