Abstract
The dual superconductivity of the vacuum in SU(3) gauge theory is investigated by constructing a disorder parameter which signals monopole condensation in various Abelian projections and by studying numerically on the lattice its behavior at finite temperature. We find that the vacuum is a dual superconductor with respect to each U(1) of the residual gauge group after Abelian projection independently of the Abelian projection chosen. As in the SU(2) case (discussed in the preceding paper) a finite size scaling analysis enables us to extract the indices of the phase transition and our analysis is consistent with independent determinations.
