Weyl symmetric Abelian Decomposition and Monopole Condensation in SU(3) QCD

We generalize the previous result of SU(2) QCD and demonstrate the monopole condensation in SU(3) QCD. We present the gauge independent and Weyl symmetric Abelian (Cho-Duan-Ge) decomposition of the SU(3) QCD, and obtain an infra-red finite and gauge invariant integral expression of the one-loop effective action. Integrating it gauge invariantly imposing the color reflection invariance (``the C-projection'') we show that the effective potential generates the stable monopole condensation which generates the mass gap.
