# BOSE CONDENSATION AND ZN SYMMETRY BREAKING IN THE MIXED MODEL OF INDUCED QCD

@article{Migdal1993BOSECA, title={BOSE CONDENSATION AND ZN SYMMETRY BREAKING IN THE MIXED MODEL OF INDUCED QCD}, author={Alexander Migdal}, journal={Modern Physics Letters A}, year={1993}, volume={08}, pages={259-273} }

The mixed model of the large-N induced QCD, with Nf≪N flavors of heavy fermions in fundamental representation, is solved in the local limit. The ZN symmetry is broken spontaneously in the large-N limit, evading the Elitzur “no-go” theorem. As a result of this symmetry breaking, there is the Bose condensate of the eigenvalues of the scalar field, proportional to . This condensate leads to the mass unit, which goes to zero as fractional power of thus defining the new kind of the local limit of… Expand

It is shown that a lattice model for induced lattice QCD has a Z[sub [ital N]] gauge symmetry which, in the strong coupling phase, results in a local confinement where only color singlets are allowed to propagate along links and all Wilson loops for nonsinglets average to zero. Expand
