چکیده
The first search for the decay K + → π + π 0 ν ¯ ν has been performed with the E787 detector at BNL. Based on zero events observed in the kinematical search region defined by 90 MeV/c < P π + < 188 MeV/c and 135 MeV < E π 0 < 180 MeV, an upper limit B(K + → π + π 0 ν ¯ ν) < 4.3 × 10 −5 at 90% confidence level is established.

A search for additional evidence for the rare kaon decay K+ → π+νν̄ has been made with a new data set comparable in sensitivity to the previous exposure that produced a single event. No new events were found in the pion momentum region examined, 211 < P < 229 MeV/c. Including a reanalysis of
متن کاملNew 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 کاملAn Experiment for the K
The rare K decay K L → π 0 νν̄ is considered as one of ideal processes in the flavor physics to make a critical test for the standard model and a search for new physics beyond it. The E391a experiment at the KEK 12-GeV proton synchrotron is the first dedicated experiment for the K L → π 0 νν̄ decay. The experiment started a data taking in February 2004 aiming at an improvement of sensitivity from...
متن کاملSearch of New Physics with Kaon decays at NA 62
the current short term phase (data taking completed in years 2007-8) we are studying the ratio RK = Γ(K→eνe(γ)) Γ(K→μνμ (γ)) of leptonic decay rates, which provides a golden probe for testing the structure of the weak interactions. In the second phase (long term) we will then focus on the measurement of the branching ratio of the very rare kaon decay K+ → π+νν̄ aiming at collecting O(100) K+→ π+...
متن کاملEvidence for the Decay K + → π + νν̄
An event consistent with the signature expected for the rare kaon decay K+ → π+νν̄ has been observed. In the pion momentum region examined, 211 < P < 230 MeV/c, the backgrounds are estimated to contribute 0.08 ± 0.03 events. If the event is due toK+ → π+νν̄, the branching ratio is 4.2 −3.5× 10−10.
