Abstract

In this talk we want to discuss the color confinement criterion which guarantees confinement of all colored particles including dynamical quarks and gluons. The most well-known criterion is the Kugo-Ojima color confinement criterion derived in the Lorenz gauge. However, it was pointed out that the Kugo-Ojima criterion breaks down for the Maximal Abelian gauge in which quark confinement has been verified according to the dual superconductivity caused by magnetic monopole condensations. We give the color confinement criterion based on the restoration of the residual local gauge symmetry which can be applied to the Abelian and non-Abelian gauge theories as well irrespective of the compact or non-compact formulation, and enables us to understand confinement in all the cases. Indeed, the restoration of the residual local gauge symmetry which was shown by Hata in the Lorenz gauge to be equivalent to the Kugo-Ojima criterion indeed occurs in the Maximal Abelian gauge for the SU(N) Yang-Mills theory in two-, three- and four-dimensional Euclidean spacetime once the singular topological configurations of gauge fields are taken into account. This result indicates that the color confinement phase is a disordered phase caused by non-trivial topological configurations irrespective of the gauge choice.

Strengths

1. Very important problem is addressed
2. MA gauge is considered which is a popular gauge for the confinement studies.
3. Nice presentation.

Report

The authors addressed the famous Kugo-Ogima criterion of color confinement. KO criterion was formulated for the Landau gauge. In the present paper it was demonstrated that the criterion is also valid for the MA gauge. The restoration of the residual local gauge symmetry was used as a method. I recommend the paper for publication after some misprints are corrected.

Requested changes

1) In the rhs of eq.(12) one of indices $\mu$ should be changed to $\nu$
2) Section 4. It is not clear why two different notations $\phi$ and $\psi$ are used for the matter field.
