Non-Abelian Meissner effect in Yang-Mills theories at weak coupling

We present a weak-coupling Yang-Mills model supporting non-Abelian magnetic flux tubes and non-Abelian confined magnetic monopoles. In the dual description the magnetic flux tubes are prototypes of the QCD strings. Dualizing the confined magnetic monopoles we get gluelumps which convert a QCD string in the excited state to that in the ground state. Introducing a mass parameter m we discover a phase transition between the Abelian and non-Abelian confinement at a critical value m=m(*)similar toLambda. Underlying dynamics are governed by a Z(N) symmetry inherent to the model under consideration. At m>m(*) the Z(N) symmetry is spontaneously broken, resulting in N degenerate Z(N) (Abelian) strings. At m1.
