Abstract

Symmetry tests in polarized Z0 decays to bb̄g were made. From the forward-backward polar-angle asymmetry of the signed-thrust axis and the azimuthal-angle asymmetry, the parity-violation parameters AP and A′P were found to be consistent with O(αs2) quantum chromodynamic (QCD) expectations. A corresponding 95% C.L. limit was set on parity violation at the bb̄g vertex. Using the event-plane normal polar-angle distributions, 95% C.L. limits were set on the T-odd and CP-even and CP-odd asymmetry parameters AT+ and AT-.
