Measurement of the K+ -> pi0 mu+ nu_mu gamma Branching Ratio

The E787 Collaboration

A measurement of the decay K+ -> pi0 mu+ nu_mu gamma has been performed with the E787 detector at Brookhaven National Laboratory. Forty events were observed in the signal region wi…

Measurement of the $K^{+} \to π^{+} ν ν ˉ$ Branching Ratio

The E949 Collaboration

Experiment E949 at Brookhaven National Laboratory studied the rare decay $K^+\toπ^+ν\barν $an d o t h er p r ocesses w i t han e x p os u r eo f$ 1.77\times 10^{12}K^+$'s. The data were anal…

First search for $K_{L} \to π^{0} π^{0} ν ν ˉ$

J. Nix

The first search for the rare kaon decay $\kppnn$ has been performed by the E391a collaboration at the KEK 12-GeV proton synchrotron. An upper limit of $4.7 \times 1 0^{- 5}$ at the 90…

Improved Measurement of the K+ to pi+ nu nubar Branching Ratio

E949 Collaboration, A. V. Artamonov

An additional event near the upper kinematic limit for K+ to pi+ nu nubar has been observed by Experiment E949 at Brookhaven National Laboratory. Combining previously reported and…

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

E787 Collaboration

We have searched for the decay $K^{+} \to π^{+} ν ν ˉ$ in the kinematic region with pion momentum below the $K^{+} \to π^{+} π^{0}$ peak. One event was observed, consistent with the backgro…

Evidence for the Decay K+ --> pi+ nu anti-nu

E787 Collaboration, S. Adler

An event consistent with the signature expected for the rare kaon decay K+ --> pi+ nu anti-nu has been observed. In the pion momentum region examined, 211<P<230 MeV/c, the backgrou…
