Quantum Chromodynamics and the Z-width
arXiv:hep-ph/9709464
Abstract
We show by explicit construction of an alternative theory for the strong interactions that it cannot be distinguished from QCD by any of the usual precision tests except on extending these theories to the full electroweak theory, by the Z- particle width.
