1 Kazakov - Migdal Induced Gauge Theory
We give the exact solution of the Kazakov-Migdal induced gauge model in the case of a D=1 compactified lattice with a generic number S of sites and for any value of N. Due to the peculiar features of the model, the partition function that we obtain also describes the vortex-free sector of the D=1 compactified bosonic string, and it coincides in the continuum limit with the one obtained by Boula...
متن کاملKazakov-migdal Induced Gauge Theory and the Coupling of 2d Quantum Gravity to D=1 Matter
Recently Kazakov and Migdal proposed a new approach to the large N limit of SU(N) gauge theories which could hopefully describe the asymptotically free fixed point of QCD in 4 dimensions. In this contribution we review the exact solution of their model in the case of a d = 1 compactified lattice and its connection with the partition function of the vortex-free sector of the d=1 compactified bos...
متن کاملAn Exact Solution of 4 D Higher - Spin Gauge Theory
We give a one-parameter family of exact solutions to four-dimensional higher-spin gauge theory invariant under a deformed higher-spin extension of SO(3, 1) and parameterized by a zeroform invariant. All higher-spin gauge fields vanish, while the metric interpolates between two asymptotically AdS4 regions via a dS3-foliated domainwall and two Robertson-Walker-like H3foliated spacetimes – one in ...
متن کاملExact Solution of Induced Lattice Gauge Theory at Large
We find the exact solution of a recently proposed model of the lattice gauge theory induced by heavy scalar field in adjoint representation at N = ∞ for arbitrary dimension D. The nonlinear integral equation for the gauge invariant density of eigenvalues of the vacuum average of the scalar field is derived. In the continuum limit, the density grows as φ α where α = 1 +
متن کاملStatus of the Kazakov–Migdal Model
In this talk I discuss both the present status and some recent work on the Kazakov–Migdal Model which was originally proposed as a soluble, large N realization of QCD. After a brief description of the model and a discussion of its solubility in the large N limit I discuss several of the serious problems with the model which lead to the conclusion that it does not induce QCD. The model is noneth...
