Solution of the Gribov problem from gauge invariance

چکیده
A new approach to gauge fixed Yang-Mills theory is derived using the Polyakov-Susskind projection techniques to build gauge invariant states. In our approach, in contrast to the Faddeev-Popov method, the Gribov problem does not prevent the gauge group from being factored out of the partition function. Lattice gauge theory is used to illustrate the method via a calculation of the static quark–antiquark potential generated by the gauge fields in the fundamental modular region of Coulomb gauge.

The standard techniques of gauge-fixing, such as covariant gauge fixing, are entirely adequate for the purposes of studies of perturbative QCD. However, they fail in the nonperturbative regime due to the presence of Gribov copies. These copies arise because standard local gauge fixing methods do not completely fix the gauge. Known Gribov-copy-free gauges, such as Laplacian gauge, are manifestly...
متن کاملLattice Gauge Fixing, Gribov Copies and Brst Symmetry
We show that a modification of the BRST lattice quantization allows to circumvent an old paradox, formulated by Neuberger, related to lattice Gribov copies and nonperturbative BRST invariance. In the continuum limit the usual BRST formulation is recovered. ⋆ Address until August 31st, 1998. ⋆⋆ Permanent address.
متن کاملSome Considerations on Lattice Gauge Fixing
Some problems related to Gribov copies in lattice gauge-fixing and their possible solution are discussed. 1 Gribov and Gauge-Fixing Problem The Faddeev-Popov[1] quantization gives a meaning to the formal (euclidean) expectation value of a gauge invariant observable operator: 〈O〉 = ∫ δA exp[−S(A)] O(A) ∫ δA exp[−S(A)] (1) The Faddeev-Popov method requires the choice of a gauge fixing condition: ...
متن کاملWeak gauge-invariance of dimension two condensate in Yang-Mills theory
We give a formal proof that the space-time average of the vacuum condensate of mass dimension two, i.e., the vacuum expectation value of the squared potential A 2 μ , is gauge invariant in the weak sense that it is independent of the gauge-fixing condition adopted in quantizing the Yang-Mills theory, at least for the small deformation from the generalized Lorentz and the modified Maximal Abelia...
متن کاملCoulomb gauge Gribov copies and the confining potential
We develop an approach to the static inter-quark potential based on Polyakov lines of finite temporal extent, evaluated in Coulomb gauge. At small spatial separations, the potential can be understood as being between two separately gauge invariant colour charges. At larger separations Gribov copies obstruct the non-perturbative identification of individually gauge invariant colour states. We sh...
