  • 摘要:A search for a T-violating transversemuon polarization (PT ) inK+ !0+ decay was carried out in the experiment E246 at the KEK-PS. The Standard model (SM) predicts vanishing value of the polarization (< 10−7), so an observation of non-zero PT at the current experimental sensitivity level would be a de nite signature of new physics beyond SM. The preliminary result of the analysis of the 1996-1998 data is presented here: PT = (−3:33:7(stat)0:9(syst))10−3, which corresponds to the T-violation parameter Im() = (−0:91:2(stat)  0:3(syst))  10−2. There is no evidence for T-violation in K3 at the current level of sensitivity.
