Description

We study the effect of maximally abelian gauge Gribov copies in the context of the dual superconductor scenario of confinement. We present a new approach to estimate the systematic uncertainties from incomplete gauge fixing. Numerical studies have been performed, in SU(2) lattice gauge theory, based on the overrelaxed simulated annealing gauge fixing algorithm. As a result, we obtain the ratio 0.92(4) between abelian and nonabelian string tensions at β = 2.5115. (orig.)
