BRST symmetry of SU(2) Yang-Mills theory in Cho–Faddeev–Niemi decomposition

چکیده
We determine the nilpotent BRST and anti-BRST transformations for the Cho–Faddeev-Niemi variables for the SU(2) Yang-Mills theory based on the new interpretation given in the previous paper of the Cho–Faddeev-Niemi decomposition. This gives a firm ground for performing the BRST quantization of the Yang–Mills theory written in terms of the Cho–Faddeev-Niemi variables. We propose also a modified version of the new Maximal Abelian gauge which could play an important role in the reduction to the original Yang-Mills theory.

Cho-Faddeev-Niemi decomposition of lattice Yang-Mills theory and evidence of a novel magnetic condensation
We present the first implementation of the Cho–Faddeev–Niemi decomposition of the SU(2) Yang-Mills field on a lattice. Our construction retains the color symmetry (global SU(2) gauge invariance) even after a new type of Maximally Abelian gauge, as explicitly demonstrated by numerical simulations. c Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercia...
متن کاملMagnetic condensation , Abelian dominance , and instability of Savvidy vacuum
We show that a certain type of color magnetic condensation originating from magnetic monopole configurations is sufficient to provide the mass for off-diagonal gluons in the SU(2) Yang-Mills theory under the Cho–Faddeev– Niemi decomposition. In fact, such magnetic condensation is shown to occur by calculating the effective potential within the BRST quantization. This enables us to explain the i...
متن کاملWilsonian effective action for SU(2) Yang-Mills theory with Cho-Faddeev-Niemi-Shabanov decomposition
The Cho-Faddeev-Niemi-Shabanov decomposition of the SU(2) Yang-Mills field is employed for the calculation of the corresponding Wilsonian effective action to oneloop order with covariant gauge fixing. The generation of a mass scale is observed, and the flow of the marginal couplings is studied. Our results indicate that higherderivative terms of the color-unit-vector n field are necessary for t...
متن کاملCompact lattice formulation of Cho-Faddeev-Niemi decomposition: string tension from magnetic monopoles
In this paper we begin on a new lattice formulation of the non-linear change of variables called the Cho–Faddeev–Niemi decomposition in SU(2) Yang-Mills theory. This is a compact lattice formulation improving the non-compact lattice formulation proposed in our previous paper. Based on this formulation, we propose a new gauge-invariant definition of the magnetic monopole current which guarantees...

We present the first implementation of the Cho–Faddeev–Niemi decomposition of the SU(2) Yang-Mills field on a lattice. Our construction retains the color symmetry (global SU(2) gauge invariance) even after a new type of Maximally Abelian gauge, as explicitly demonstrated by numerical simulations. Moreover, we propose a gauge-invariant definition of the magnetic monopole current using this formu...
