Further search for T-violation in the decay K+ → π0μ+η

Abstract A new result for the transverse μ + polarization, P T , in the decay K + → μ 0 μ + η has been obtained in the KEK E246 experiment. Combined with our earlier result, P T = (−1.12 ± 2.17( stat ) ± 0.90( syst )) × 10 −3 and Im( ζ ) = (−0.28 ± 0.69( stat ) ± 0.30( syst )) × 10 −2 , which are consistent with no T-violation.
