Abstract
We have made the first direct symmetry tests in the decays of polarized Z0 bosons into fully-identified b bbar g states, collected in the SLD experiment at SLAC. We searched for evidence of parity violation at the b bbar g vertex by studying the asymmetries in the b-quark polar- and azimuthal-angle distributions, and for evidence of T-odd, CP-even or odd, final-state interactions by measuring angular correlations between the three-jet plane and the Z0 polarization. We found results consistent with Standard Model expectations, and set 95% C.L. limits on anomalous contributions.
