Abstract

We present the first measurement of the correlation between the Z(0) spin and the event-plane orientation in polarized Z(0) 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) over right arrow(Z) .((k) over right arrow(1) x (k) over right arrow(2)), formed from the two fastest jet momenta (k) over right arrow(1) and (k) over right arrow(2) and the Z(0) polarization vector (S) over right arrow(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 < beta < 0.039 on the correlation.
