Abstract:We study infrared abelian dominance and the dual Higgs mechanism in the maximally abelian (MA) gauge using the lattice QCD Monte Carlo simulation. In the MA gauge, the off-diagonal gluon phase tends to be random, and the off-diagonal gluon A ± µ acquires the effective mass as M off ≃ 1.2 GeV. From the monopole current in the MA gauge, we extract the dual gluon field B µ and estimate the dual gluon mass as m B ≃ 0.5 GeV. The QCD-monopole structure is also investigated in terms of off-diagonal gluons. From the l… Show more
