R$_{b}$ in supersymmetric models
We compute the supersymmetric contribution to R_{b}\equiv \Gamma (Z\to b{\bar b})/\Gamma (Z\to {\rm hadrons}) in a variety of supersymmetric models. In the context of supergravity models with universal soft-supersymmetry-breaking and radiative electroweak breaking we find R^{\rm susy}_b\lsim0.0004,...
