Decays from Experiment E787

چکیده
This paper presents the latest results from experiment E787, at Brookhaven National Laboratory, on K + → π + νν and radiative K + decays. The result for K + → π + νν uses data collected in runs taken during 1995, 1996 and 1997. In addition, we discuss plans for future measurements of K + → π + νν. This decay mode is a very clean probe of the dynamics of the Cabbibo-Kobayashi-Maskawa (CKM) mixing matrix. It is a ∆S = 1 process which proceeds via the box diagram and electroweak penguin diagrams 1). Since the top quark is so much more massive than the other up-type quarks, its contribution dominates

New results for K+→π+νν at low π+ momentum from BNL E949
The BNL E949 experiment was a successor to BNL E787 and was aimed to measure the branching ratio of the K+ → π+νν̄ decay. After detector upgrades were made, data equivalent to 1.7 × 1012 K+ decays at rest were collected in a 2002 physics run. The data were analyzed via a blind analysis with a technique called the “Bifurcation Method”. In this report we present the results of a search for K+ → π+...
متن کاملK → πνν̄ from standard to new physics
Flavour changing neutral current decays are a very sensitive test of the standard model and its extensions. In particular the decay K → πνν̄ constitutes a clean way to provide constraints, independent of long distance effects. Motivated by the recent experimental data of the E787 and E865 collaborations and by the difference between the standard model prediction and data, we consider in detail n...

متن کاملFuture Kac ) n Programs at BNL , FNAL 1
Future kaon decay programs at BNL and FNAL are discussed. The primary focus of these programs is the measurement of the golden modes, K: -+ n“v~ and K+ -+ m+VD . The observation of K+ -+ T+VD by E787 at BNL is the first step in a series of measurements which will completely determine the unitarity triangle within the kaon system. The next step after E787 in the measurement of B(K+ + n+vfi ) wil...
