Gribov vacuum copies in terms of harmonic maps

Journal Article · · Phys. Rev., D; (United States)

We discuss the structure of the Gribov vacuum copies for SU(2) non-Abelian gauge theories in the Landau gauge. Using the theory of the harmonic maps, we recover the known Gribov-type solutions and construct new ones which are not spherically symmetric.
