The analyses take advantage of the excellent vertexing efficiency and resolution of the pixel-based CCD Vertex Detector. All analyses determine the B flavor at production by exploiting the large forward-backward asymmetry of polarized Z->bb decays and using additional information from the hemisphere opposite that of the reconstructed B decay. Four separate analyses are presented. Two analyses select semileptonic B decays and two analyses reconstruct inclusive B decays. The analyses are combined to set a lower limit on the Bs mixing oscillation frequency with a sensitivity comparable to that of the current world average.
