Additional evidence for the rare kaon decay K+-->pi+nu(nu) has been found in a new data set with comparable sensitivity to the previously reported result. One new event was observed in the pion momentum region examined, 211<P<229 MeV/c, bringing the total for the combined data set to two. Including all data taken, the backgrounds were estimated to(More)
Brookhaven experiment E949 has continued the search for the rare decay K + → π + ν ¯ ν. The branching ratio for this second-order weak transition is an important test of the Standard Model; deviations from the predicted branching ratio of ∼ 0.8 × 10 −10 could be indications of non-Standard Model physics. While the Standard Model prediction for the branching(More)
Experiment E949 at Brookhaven National Laboratory studied the rare decay K ‡ ! ‡ and other processes with an exposure of 1:77 10 12 K ‡ 's. The data were analyzed using a blind analysis technique yielding one candidate event with an estimated background of 0:30 0:03 events. Combining this result with the observation of two candidate events by the(More)
