Abstract
We present measurements of Rb using the SLD at the SLC. The analyses u se 2D and 3D impact parameter tags and a displaced 3D vertex tag which all exploit the small size and stability of the e(+)e(-) interaction point and the precision 3D CCD pixel vertex detector to achieve high < b(b)over bar>-tagging efficiencies and purities. The combined measurem ent yields R(b) = 0.229 +/- 0.011 and is consistent with standard mode l predictions.
