Measurements of Ab, Rb and the B±,0 lifetimes at the Z0 resonance by SLD

Rb, Ab and the lifetimes of the B+ (Bu) and B0 (Bd) mesons have been measured using a sample of 150 000 hadronic Z0 decays collected by the SLD experiment at the SLC between 1993 and 1995. The analyses make use of a novel topological vertexing technique to obtain charge, decay length and vertex mass. The asymmetry Ab is measured with a self-calibrating technique employing momentum-weighted track charge from both hemispheres in the tagged events as well as by using the polar angle dependency of the Z0-pole polarized cross section and tagging the bottom and charmed hadrons in the semileptonic decay channel.
