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…

Search for the Decay $K_{L}^{0} \to π^{0} ν ν ˉ$

E391a Collaboration, J. K. Ahn

We performed a search for the $K_{L}^{0} \to π^{0} ν ν ˉ$ decay at the KEK 12-GeV proton synchrotron. No candidate events were observed. An upper limit on the branching ratio for the de…

New limit on the $K_{L}^{0} \to π^{0} ν ν ˉ$ decay rate

E391a Collaboration, J. K. Ahn

The first dedicated experiment for the rare kaon decay $K_{L}^{0} \to π^{0} ν ν ˉ$ has been performed by the E391a collaboration at the KEK 12-GeV proton synchrotron. A new upper limit…

Upper Limit on the Branching Ratio for the Decay $π^{0} \to ν ν ˉ$

E949 Collaboration, A. V. Artamonov

A sample of kinematically identified $K^{+} \to π^{+} π^{0}$ decays obtained with the E949 detector was used to search for the helicity-suppressed decay $π^{0} \to ν ν ˉ$ resulting in an…

Search for the decay K+ to pi+ gamma gamma in the pi+ momentum region P>213 MeV/c

E949 Collaboration, A. V. Artamonov

We have searched for the K+ to pi+ gamma gamma decay in the kinematic region with pi+ momentum close to the end point. No events were observed, and the 90% confidence-level upper l…

Further search for the decay $K^{+} \to π^{+} ν ν ˉ$ in the momentum region P < 195 MeV/c

E787 Collaboration

We report the results of a search for the decay $K^{+} \to π^{+} ν ν ˉ$ in the kinematic region with $π^{+}$ momentum $140 < P < 195$ MeV/c using the data collected by the E787 experim…

Measurement of Structure Dependent K^+ -> mu^+ nu gamma

E787 Collaboration

We report the first measurement of a structure dependent component in the decay K^+ -> mu^+ nu gamma. Using the kinematic region where the muon kinetic energy is greater than 137 M…

Further Search for the Decay K^+ --> pi^+ nu nubar

E787 collaboration

A search for additional evidence for the rare kaon decay K^+ --> pi^+ nu nubar has been made with a new data set comparable in sensitivity to the previous exposure that produced a…
