Abstract
We present the first measurement of the correlation between the Z0 spin and the event-plane orientation in polarized Z0 decays into three jets in the SLAC Linear Collider Large Detector experiment at SLAC utilizing a longitudinally polarized electron beam. The CP-even and T-odd triple product S→Z·(k→1×k→2), formed from the two fastest jet momenta k→1 and k→2 and the Z0 polarization vector S→Z, is sensitive to physics beyond the standard model. We measure the expectation value of this quantity to be consistent with zero and set 95% C.L. limits of -0.022<β<0.039 on the correlation.
