Gauge theories induced by bosons in fundamental representation

چکیده
A lattice theory of scalar bosons in the fundamental representation of the gauge group SU(Nc) and of the global symmetry group SU(Nf) is shown to induce a standard gauge theory only at large Nf . The system is in a deconfined phase at strong scalar self-coupling and any finite Nf . The requirement of convergence of the effective gauge action imposes a lower limit on the scalar mass.

Vortex solutions in SU(N ) adjoint Higgs theories
A relationship between vortex solutions in SU(N) gauge theories with two or more adjoint representation Higgs bosons and thick vortices of Center Vortex Theory is shown to exist. There is a similar relationship between monopole solutions of SU(N) gauge theories with a single adjoint representation Higgs boson and monopoles in Abelian Projection. New vortex solutions, relevant in central gauge f...
متن کاملVortex solutions in nonabelian Higgs theories
A new class of vortex solutions is found in SU(2) gauge theories with two adjoint representation Higgs bosons. Implications of these new solutions and their possible connection with Center Gauge fixed pure gauge theories are discussed. PACS numbers: 11.15Kc, 11.15Ha, 12.38Aw The classification of vortex solutions in SU(N) gauge theories requires the investigation of mapping rotations around the...
متن کاملM ar 1 99 8 Non - abelian gauge theories as a consequence of perturbative quantum gauge invariance ∗
We show for the case of interacting massless vector bosons, how the structure of non-abelian gauge theories emerges automatically from a more fundamental concept of quantum field theories, namely perturbative quantum gauge invariance. It turns out that the coupling is necessarily of Yang-Mills type plus divergence-and coboundary couplings. The extension of the method to massive gauge theories i...
متن کاملSolution of gauge theories induced by fundamental representation scalars
Gauge theories induced by scalars in the fundamental representation of the U(Nc)gauge×U(Nf )global group are investigated in the large Nc and Nf limit. A master field is defined from bilinears of the scalar field following an Eguchi-Kawai type reduction of spacetime. The density function for the master field satisfies an integral equation that can be solved exactly in two dimensions (D = 2) and...
متن کاملComplementarity between Gauge-Boson Compositeness and Asymptotic Freedom — with scalar matter
We derive and solve the compositeness condition for the SU(Nc) gauge boson coupling with Ns scalar fields at the next-to-leading order in 1/Ns and the leading order in lnΛ (Λ is the compositeness scale). It turns out that the argument of gauge-boson compositeness (with a large Λ) is successful only when Ns/Nc > 22, in which the asymptotic freedom fails, as is in the previously investigated case...
