摘要

We present the first measurement of the correlation between the Z(sup 0) spin and the event plane orientation in polarized Z(sup 0) decays into three jets in the SLD experiment at SLAC utilizing a longitudinally polarized electron beam. The CP even and T odd triple product (rvec S)(sub Z)(center dot) ((rvec k)(sub 1) x (rvec k)(sub 2)) formed from the two fastest jet momenta, (rvec k)(sub 1) and (rvec k)(sub 2), and the Z(sup 0) polarization vector (rvec S)(sub 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(lt) (beta) (lt)0.039 on the correlation.
