✦ Synopsis

We show the construction of the dual superconducting theory for the confinement mechanism from QCD in the maximally abelian (MA) gauge using the lattice QCD Monte Carlo simulation. We find that essence of infrared abelian dominance is naturally understood with the off-diagonal gluon mass mo~ -~ 1.2GeV induced by the MA gauge fixing. In the MA gauge, tile off-diagonal gluon amplitude is forced to be small, and the off-diagonal gluon phase tends to be random. As tile mathematical origin of abelian dominance for confinement, we demonstrate that the strong randomness of the off-diagonal gluon phase leads to abelian dominance tbr the string tension. In the MA gauge, there appears the macroscopic network of the monopole world-line covering the whole system. We investigate the monopole-current system in the MA gauge by analyzing the dual gluon field Bt,. We evaluate the dual gluon mass as mB = 0.4 ,-~ 0.5GeV in the infrared region, which is the lattice-QCD evidence of the dual Higgs mechanism by monopole eondensation. Owing to infrared abelian dominance and infrared monopole condensation, QCD in the MA gmlge is describable with the dual Ginzburg-Landau theory.
