SLAC-SLD Collaboration. Measurement of correlation between the Z spin and the three-jet plane orientation in polarized Z decays into three jets utilizing a longitudinally polarized electron beam. The CP-even and T-odd triple product Sz*[k1,k2] is formed from the two fastest jet momenta, k1 and k2, and the Z polarization vector Sz, and it vanishes identically at tree level.
