Apparatus for a Search for T-violating Muon Polarization in Stopped-Kaon Decays
نویسنده
چکیده
The detector built at KEK to search for T-violating transverse muon polarization in K → πμνμ (Kμ3) decay of stopped kaons is described. Sensitivity to the transverse polarization component is obtained from reconstruction of the decay plane by tracking the μ through a toroidal spectrometer and detecting the π in a segmented CsI(Tl) photon calorimeter. The muon polarization was obtained from the decay positron asymmetry of muons stopped in a polarimeter. The detector included features which minimized systematic errors while maintaining high acceptance.

New search for T - violation in the decays of the charged kaon
We report the results of the measurement of T-violating transverse muon polarization in the decays K + → µ + ν µ π 0 (K µ3) and K + → µ + ν µ γ (K µ2γ) performed in the experiment E246 at KEK. Preliminary results obtained for the entire data set taken in the period 1996-2000 are consistent with no T-violation in both decays.
متن کاملOverview of Kaon Decay Physics
After a brief history of the insights gained from Kaon physics, the potential of Kaon decays for probing lepton number violation is discussed. Present tests of CTP and of Quantum Mechanics in the neutral Kaon sector are then reviewed and the potential of the Frascati Φ factory for doing incisive tests in this area is emphasized. The rest of this overview focuses on CP violating effects in the K...
متن کاملT - odd correlations in charged K l 4 decays
We analyse the sensitivity to physics beyond the SM of T-odd correlations in Kl4 decays, which do not involve the lepton polarization. We show that a combined analysis of K μ4 andK μ4 decays can lead to new constraints about CP violation in ∆S = 1 charged-current interactions, complementary to those obtained from the transverse muon polarization in Kμ3 and of comparable accuracy. I. Charged kao...
متن کاملKaon Physics with a High-intensity Proton Driver
We study opportunities for future high-precision experiments in kaon physics using a high-intensity proton driver, which could be part of the front-end of a muon storage ring complex. We discuss in particular the rare decays KL → π0νν̄, K+ → π+νν̄, KL → π0e+e−, and lepton-flavour violating modes such as KL → μe and K → πμe. The outstanding physics potential and longterm interest of these modes is...
متن کاملCharged-Lepton-Flavour Violation in Kaon Decays in Supersymmetric Theories
We discuss rare kaon decays that violate charged-lepton flavour conservation in supersymmetric theories with and without R parity, in view of possible experiments using an intense proton source as envisaged for a neutrino factory. In the Minimal Supersymmetric Standard Model, such decays are generated by box diagrams involving charginos and neutralinos, but the limits from μ → eγ, μ–e conversio...
