A try to investigate color confinement directly from QCD Lagrangian

In the SU(N) case authors use the Fadeev-Niemi topological decomposition of nonabelian gauge potentials to derive the low energy effective Lagrangian under one loop approximation by integrating all degrees of freedom except the topological ones in its path integral. The result supports a mechanism on color confinement which comes from the dual Misner Effect. The effect from fermion fields is also discussed. (author)
