A new limit of T-violating transverse muon polarization in the decay
M. Abe, M. Aliev, V. Anisimovsky +27
A search for T-violating transverse muon polarization () in the decay was performed using kaon decays at rest. A new improved value, $P_T= -0.0017\pm 0.…
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…
New search for T-violation in the decays of the charged kaon
V. Anisimovsky, A. Ivashkin, Yu. Kudenko
We report the results of the measurement of T-violating transverse muon polarization in the decays K^+ --> pi^0 mu^+ nu and K^+ --> mu^+ nu gamma performed in the experiment E246 a…
First measurement of the T-violating muon polarization in the decay K^+ --> mu^+ nu gamma
V. V. Anisimovsky, A. N. Khotjantsev, A. P. Ivashkin
We present the result of the first measurement of the T-violating muon polarization P_T in the decay K^+ --> mu^+ nu gamma. This polarization is sensitive to new sources of CP-viol…
