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…
