Compositeness of gauge boson and asymptotic freedom in non-abelian gauge theory
In order to investigate the composite gauge field, we consider the compositeness condition (i.e. renormalization constant Z3 = 0) in the general non-abelian gauge field theory. We calculate Z3 at the next-to-leading order in 1/Nf expansion (Nf is the number of fermion flavors), and obtain the expression to the gauge coupling constant through the compositeness condition. Then the gauge coupling ...
متن کاملGauge Freedom in Chiral Gauge Theory with Vacuum Overlap
In the vacuum overlap formalism[1] of a generic chiral gauge theory, gauge symmetry is explicitly broken by the complex phase of fermion determinant. In order to restore the gauge invariance, gauge average—the integration along gauge orbit— is invoked. Then, what is required for the dynamical nature of the gauge freedom at β = ∞ (pure gauge limit) is that the global gauge symmetry is not broken...
متن کاملThe Maximal Abelian Gauge in SU(3) Lattice Gauge Theory
We gauge fix 600 SU(3) β = 6.0 configurations on a 16 lattice to a simple form of the maximal abelian gauge. We project the SU(3) valued links to the U(1) × U(1) subgroup, and extract U(1) × U(1) and monopole string tensions. After gauge fixing to the indirect center gauge, the U(1)×U(1) links are projected to Z(3) and a vortex string tension is measured. The vortex and magnetic current densiti...
متن کاملPath Integral Quantization of Dual Abelian Gauge Theory
The path integral for 3+1 abelian gauge theory is rewritten in terms of a real antisymmetric field allowing a dual action that couples the electric and magnetic currents to the photon and each other in a gauge invariant manner. Standard perturbative abelian quantum electrodynamics reemerges when the monopole current vanishes. For certain simple relationships between the monopole current and the...
متن کاملVortices in (abelian) Chern-Simons gauge theory
The vortex solutions of various classical planar field theories with (abelian) Chern-Simons term are reviewed. Relativistic vortices, put forward by Paul and Khare, arise when the Abelian Higgs model is augmented with the Chern-Simons term. Adding a suitable sixth-order potential and turning off the Maxwell term provides us with pure Chern-Simons theory with both topological and non-topological...
