Abstract

The rare kaon decay K+→π+νν̄ was observed in a data set with comparable sensitivity. The observable signature for K+→π+νν̄ decay from kaons involved the π+ track and π+ decay products. The maximum pion momentum from K+→π+νν̄ decay at rest was found to be 227 MeV/c.

Abstract

A new measurement of the branching ratio R_{e/μ}=Γ(π^{+}→e^{+}ν+π^{+}→e^{+}νγ)/Γ(π^{+}→μ^{+}ν+π^{+}→μ^{+}νγ) resulted in R_{e/μ}^{exp}=[1.2344±0.0023(stat)±0.0019(syst)]×10^{-4}. This is in agreement with the standard model prediction and improves the test of electron-muon universality to the level of 0.1%.

Abstract

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) consistent with the standard model prediction.

Abstract

Introduction: Excess bodyweight is known to be associated with many medical disorders which can be disqualifying for aviators. The actual prevalence of these conditions and associations with BMI in U.S. airmen has not been previously defined. This project explores overweight and obesity in valid holders of U.S. aeromedical certificates as of November 2003., Methods: A de-identified database of all holders of valid FAA medical certificates was queried for pilot's BMI and a variety of co-morbid conditions that have been associated with obesity and overweight. There were a total of 630,670 airmen. Conditions included: hypertension, diabetes, myocardial infarction, sleep apnea, kidney stones, gall bladder disease, arthritis, and hypothyroidism, among others., Results: The total prevalence of overweight and obese airmen is as follows: 47.15% are overweight and 21.11% obese. In regards to class of airmen, 48.48% of 1st class pilots are overweight and 15.35% obese, 2nd class are 47.58% overweight and 22.44% obese, and for 3rd class, 46.18% are overweight and 23.78% obese. Female pilots have a much lower prevalence of overweight and obesity. Most associations between BMI and health conditions were expected. A unique finding was that overweight and obese pilots are more likely to require a special issuance certificate than normal weight pilots., Conclusion: This data for all U.S. certificate holders suggests that conditions associated with excessive bodyweight will account for disqualification of a significant number of aviators.

Abstract

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

Abstract

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, 211pi+nu(nu)) = 1.57(+1.75)(-0.82)x10(-10).

9. Measurement of direct photon emission in K+-->pi(+)pi(0)gamma decay

Abstract

We have performed a measurement of the K+-->pi(+)pi(0)gamma decay and have observed 2x10(4) events. The best fit to the decay spectrum gives a branching ratio for direct photon emission of (4.7+/-0.8+/-0. 3)x10(-6) in the pi(+) kinetic energy region of 55 to 90 MeV and requires no component due to interference with inner bremsstrahlung.
