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…
New measurement of the K+ => pi+,nu,nubar branching ratio
E949 Collaboration
Three events for the decay K+ => pi+,nu,nubar have been observed in the pion momentum region below the K+ => pi+,pi0 peak, 140 < P_pi < 199 MeV/c, with an estimated background of 0…
Measurement of K^+ \to π^0 μ^+ νγdecay using stopped kaons
E470 Collaboration, S. Shimizu, K. Horie +17
The K^+ \to π^0 μ^+ νγ() decay has been measured with stopped positive kaons at the KEK 12 GeV proton synchrotron. A sample containing 125 events was obtained.…
Further Evidence for the Decay K+ to pi+ neutrino-antineutrino
E787 Collaboration
Additional evidence for the rare kaon decay K+ to pi+ neutrino-antineutrino has been found in a new data set with comparable sensitivity to the previously reported result. One new…
Search for the rare decay K+ -> pi+ gamma
E787 Collaboration
We have performed a search for the angular-momentum forbidden decay K+ -> pi+ gamma with the E787 detector at BNL. No events were observed in the pi+ kinematic region around 227 Me…
Measurement of Direct Photon Emission in K^+ -> pi^+ pi^0 gamma Decay
E787 Collaboration
We have performed a measurement of the K^+ -> pi^+ pi^0 gamma decay and have observed 2 X 10^4 events. The best fit to the decay spectrum gives a branching ratio for direct photon…
