Abstract

We present a model--independent analysis of the Z b b vertex, with the aim of constraining contributions of new physics to the left- and right--handed couplings of the b. We find that the left--handed coupling of the b is quite narrowly constrained by present data, but that the right--handed coupling is still largely unconstrained.
