An Analysis of Non-Oblique Corrections to the $Zb\bar{b}$ Vertex

Abstract

We present a model--independent analysis of the $Zb\bar{b}$ 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.
