Gribov Problem and Brst Symmetry †
After a brief historical comment on the study of BRS(or BRST) symmetry , we discuss the quantization of gauge theories with Gribov copies. A path integral with BRST symmetry can be formulated by summing the Gribov-type copies in a very specific way if the functional correspondence between τ and the gauge parameter ω defined by τ(x) = f(Aμ(x)) is “globally single valued”, where f(A ω μ(x)) = 0 s...
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 کاملThe nilpotent BRST symmetry for the Gribov-Zwanziger theory
We have obtained the nilpotent BRST symmetry of Yang-Mills theory restricted to the Gribov region. In fact, we give a modified BRST transformation that leaves the Gribov-Zwanziger action invariant and obeys the nilpotency, although the usual BRST symmetry is broken due to the non-vanishing Gribov parameter representing the presence of the Gribov horizon in the configuration space of the Yang-Mi...
متن کاملGribov vs BRST
We investigate the way in which the Gribov problem is manifested in the BRST quantization of simple quantum mechanical models by comparing models with and without a Gribov problem. To keep contact with the measure and action of the Faddeev-Popov path integral we quantize in the Hilbert space with conventional inner product and we consider only the conventional choice of the gauge fixing fermion...
متن کاملNonperturbative Spontaneous Symmetry Breaking
One of the most astonishing results of quantum field theory is spontaneous symmetry breaking. One can say that it is the situation when something arises from the quantization. This means that on the quantum level one has something that was not present on the classical level. Coleman and Weinberg [1] write : “ . . . higher-order effects may qualitatively change the character of a physical theory...
