First Measurement of the T-Odd Correlation Between the {Zeta}{sup 0} Spin and the Three-Jet Plane Orientation in Polarized {Zeta}{sup 0} Decays to Three Jets

PDF Version Also Available for Download.

Description

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 ... continued below
