Bose Condensation and Z_{N} Symmetry Breaking in the Mixed Model of Induced QCD
Abstract
The mixed model of the largeN induced QCD, with N_{f}≪N flavors of heavy fermions in fundamental representation, is solved in the local limit. The Z_{N} symmetry is broken spontaneously in the largeN limit, evading the Elitzur "nogo" theorem. As a result of this symmetry breaking, there is the Bose condensate of the eigenvalues of the scalar field, proportional to {N_{f}}/N. This condensate leads to the mass unit, which goes to zero as fractional power of {N_{f}}/{N} thus defining the new kind of the local limit of this lattice theory. There is a strong coupling region below this mass scale, which revives the hopes of induction of realistic QCD.
