Title:Color confinement and monopole dominance 

Abstract:
Quark confinement mechanism is one of unsolved important problems. In
the dual superconductor picture of color confinement, it is considered
that the color flux tube between quarks is caused by the condensation of
color magnetic monopoles in the QCD vacuum. In this talk, we show new
results of monopole dominance and the dual Meissner effect due to QCD
monopoles in pure SU(3) gauge theory. We discuss the vacuum type by
evaluating the Ginzburg-Landau parameter through the measurements of
Abelian electric field and Abelian squared monopole density without
gauge fixing.
