摘要：

An improved search for a T-violating transverse muon polarization (P-T) in K+ --> pi(0)mu(+)nu decay was performed using kaon decays at rest. By means of this method, PT was extracted with small systematic errors, P-T = -0.0042 +/- 0.0049(stat) +/- 0.0009(syst), and the T-violation parameter was determined to he Im xi = -0.013 +/- 0.016(stat) +/- 0.003(syst).
