Symmetry and Observables in Induced QCD
Gordon W. Semenoff, Nathan Weiss
Abstract
We review some of the basic features of the Kazakov-Migdal model of induced QCD. We emphasize the role of ZN symmetry in determining the observable properties of the model and also argue that it can be broken explicitly without ruining the solvability of induced QCD in the infinite N limit. We outline the sort of critical behavior which the master field must have in order that the model is still solvable. We also review some aspects of the D=1 version of the model where the partition function can be obtained analytically.
