Abstract

A new method is proposed for measuring a T-violating muon polarization in the decays K ⁺ → π⁰μ⁺ν and K ⁺ → μ⁺νγ. The method is based on a complete reconstruction of kinematics in these decays by using a high-resolution π⁰ detector, an active muon polarimeter, and a nearly 4π efficient photon veto system. A high acceptance of the detector allows one to reach a statistical sensitivity to the T-violating muon polarization of less than 10⁻⁴ in an experiment with stopped K ⁺ mesons.
