Search for heavy neutrinos in decays
A. V. Artamonov, B. Bassalleck, B. Bhuyan +57
Evidence of a heavy neutrino, , in the decays was sought using the E949 experimental data with an exposure of stopped kaons. With the major…
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 the Branching Ratio
The E949 Collaboration
Experiment E949 at Brookhaven National Laboratory studied the rare decay $K^+\toπ^+ν\barν1.77\times 10^{12}K^+$'s. The data were anal…
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 in the momentum region
E787 Collaboration
We have searched for the decay in the kinematic region with pion momentum below the peak. One event was observed, consistent with the backgro…
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…
Search for the Decay K+ -> pi+ pi0 nu nubar
E787, :, S. Adler +45
The first search for the decay K^+ -> pi^+ pi^0 nu nubar has been performed with the E787 detector at BNL. Based on zero events observed in the kinematical search region defined by…
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…
Upper Limit on the Decay K+ --> e+ nu mu+ mu-
E787 Collaboration, S. Adler, M. S. Atiya +37
An upper limit on the branching ratio for the decay K+ --> e+ nu mu+ mu- is set at 5.0 x 10^{-7} at 90% confidence level, consistent with predictions from chiral perturbation theor…
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…
