Abstract

We present measurements of R_b using the SLD at the SLC. The analyses use 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 bb_-tagging efficiencies and purities. The combined measurement yields R_b=0.229±0.011 and is consistent with standard model predictions.

The analyses use 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 bb_-tagging efficiencies and purities. The combined measurement yields Rb=0.229±0.011 and is consistent with standard model predictions.
