Using an impact parameter tag to select an enriched sample of Z0 → bb events, and the net momentum-weighted track charge to identify the sign of the charge of the underlying b quark, we have measured the left-right forward-backward asymmetry for b quark production as a function of polar angle. Based on 1.8 pb−1 of Z0 decay data produced with a mean electron beam polarization of Pe = 63%, this yields a direct measurement of the extent of parity violation in the Zbb coupling of Ab = 0.87± 0.11(stat.)± 0.09(syst.).
