An Analysis of Non-Oblique Corrections to the Z b b Vertex
Tatsu Takeuchi, Aaron K. Grant, Jonathan L. Rosner
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.
