Abstract
The highly accurate Kadanoff lower-bound renormalization group for spin systems is generalized to models with local gauge symmetry. As an example it is applied to the gauge-Higgs theory. The two critical exponents of the model are, respectively, predicted exactly and with 0.1% accuracy by a simple analytic calculation. The application of the generalized method to more complicated gauge groups in arbitrary spacetime dimension is described.
