EVENT HANDEDNESS IN E(-) ANNIHILATION TO 3 JETS()E()

We discuss rescattering effects that can be measured in e(+)e(-) annih ilation to three jets through a single gauge boson, by using triple pr oduct(''event handedness'') correlations of the Z (gamma) polarizatio n with jet momenta. The gauge boson polarization may be produced eithe r by polarized beams or through the natural polarization (left-right a symmetry) of the Z. QCD rescattering does not generate triple product correlations at one loop for massless quarks. We therefore calculate t he QCD contribution for massive quarks, as well as the contribution of W and Z exchange loops for massless quarks. Because of the various ca ncellations, the standard model predictions for triple-product correla tions at the Z are very small, making such measurements potentially se nsitive to physics beyond the standard model. For example, the effects of a new gauge boson that couples only to baryon number may be larger than the standard model contributions; however, the effects would pro bably still be too small to effectively constrain it.
