Test of time reversal invariance in K-mu 3 decay

An experiment E246 at the 12-GeV proton synchrotron at KEK (KEK-PS), which is searching for the T-violating transverse muon polarization (P-mu(perpendicular to)) in K+ --> pi (0)mu (+)nu decay, is described. The search is sensitive to new mechanisms of T or CP violation beyond the Standard Model. The initial results of P-mu(perpendicular to) = -0.0042+/-0.0049(stat.)+/-0.0009(syst.) and the T-violating parameter Im(xi) = -0.013+/- 0.016(stat.) +/- 0.003(syst.) were determined from the data taken in 1996 and 1997

Search for T-violating transverse muon polarization in K+->pi(0)mu(+)nu decay

An experiment searching for a T-violating transverse muon polarization (Pr) in K+ --> pi (0)mu (+)nu decay is underway at the 12-GeV proton synchrotron at KEK (KEK-PS). This search is sensitive to new mechanisms of T or CP violation beyond the Standard Model. The expected sensitivity from 1996-98 data is presented based on the published result from 1996-97 data and the new result from 1998 data
