The problems with the Z N symmetry breaking in the induced QCD are analyzed. We compute the Wilson loops in the strong coupling phase, but we do not find the Z N symmetry breaking, for arbitrary potential. We suggest to bypass this problem by adding to the model a heavy fermion field in a fundamental representation of SU (N). Remarkably, the model still can be solved exactly by the Rieman-Hilbert method, for arbitrary number N f of flavors. At N f ≪ N → ∞ there is a new regime, with two vacuum… CONTINUE READING
