摘要:There are some simple but fundamental questions in the quantum chromodynamics (QCD):
i) Color monopoles might play an important role in the origin of confinement.
Where are the real monopoles in real QCD?
(ii) What is the microscopic structure of the vacuum in QCD?
(iii) What is the origin of color confinement, why the color symmetry is
conserved and the electroweak symmetry is broken?
  We show that classical monopole solutions do exist in the real QCD and they
can provide vacuum condensate in QCD in analogy with electron Coper pair condensation
in ordinary superconductor. This resolves a long-standing problem (since 1980s)
of stable vacuum in QCD and may open new avenue in non-perturbative quantization of QCD.
