Search for the decay

Y. C. Tung, Y. B. Hsiung, J. K. Ahn +66

We performed a search for the decay with the E391a detector at KEK. In the data accumulated in 2005, no event was observed in the signal region. Based on the…

Experimental study of the decay

The E391a Collaboration, J. K. Ahn

The first dedicated search for the rare neutral-kaon decay has been carried out in the E391a experiment at the KEK 12-GeV proton synchrotron. The final upper li…

New measurement of the K+ => pi+,nu,nubar branching ratio

E949 Collaboration

Three events for the decay K+ => pi+,nu,nubar have been observed in the pion momentum region below the K+ => pi+,pi0 peak, 140 < P_pi < 199 MeV/c, with an estimated background of 0…

First search for

J. Nix

The first search for the rare kaon decay $\kppnn$ has been performed by the E391a collaboration at the KEK 12-GeV proton synchrotron. An upper limit of at the 90…

Mesonic and nonmesonic weak decay widths of medium-heavy lambda hypernuclei

Y. Sato, S. Ajimura, K. Aoki +16

We have measured the energy spectra of pions and protons emitted in the weak decay of 12_Lambda_C, 28_Lambda_Si, and Lambda_Fe hypernuclei produced via the (pi+, K+) reaction. The…

Improved Measurement of the K+ to pi+ nu nubar Branching Ratio

E949 Collaboration, A. V. Artamonov

An additional event near the upper kinematic limit for K+ to pi+ nu nubar has been observed by Experiment E949 at Brookhaven National Laboratory. Combining previously reported and…
