Three events for the decay K+-->pi+ nunu have been observed in the pion momentum region below the K+-->pi+pi0 peak, 140 < Ppi < 199 MeV/c, with an estimated background of 0.93+/-0.17(stat.) -0.24+0.32(syst.) events. Combining this observation with previously reported results yields a branching ratio of B(K+-->pi+ nunu) = (1.73(-1.05)+1.15) x 10(-10)(More)
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)
The pharmacy computer system developed and implemented at the New England Medical Center (NEMC) is described. The system was developed to improve the department's fiscal performance and operations. It operates on NEMC's large mainframe system and has the following components-order entry, unit dose/patient profile, i.v. admixture, and financial/management.(More)
An additional event near the upper kinematic limit for K+-->pi(+)nunu; has been observed by experiment E949 at Brookhaven National Laboratory. Combining previously reported and new data, the branching ratio is B(K+-->pi(+)nunu;)=(1.47(+1.30)(-0.89))x10(-10) based on three events observed in the pion momentum region 211<P<229 MeV/c. At the measured central(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)
We have performed a measurement of the K 1 ! p 1 p 0 g decay and have observed 2 3 10 4 events. The best fit to the decay spectrum gives a branching ratio for direct photon emission of ͑4.7 6 0.8 6 0.3͒ 3 10 26 in the p 1 kinetic energy region of 55 to 90 MeV and requires no component due to interference with inner bremsstrahlung.
