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 experiment E246 at KEK. The preliminary results obtained for the entire data set taken in the period 1996–2000 are consistent with no T violation in both decays.
