Electric quark confinement in 3 + 1 dimensions

It is demonstrated that the SU(N) Georgi-Glashow model contains at least two phases. While in the weak coupling regime there arise a photon and a magnetic monopole among physical particles, in the strong coupling regime the photon acquires a dynamical mass and the vacuum becomes a condensed phase of Wu-Yang monopoles. It is then shown that in the strong coupling regime quarks are confined permanently by quantized electric flux stretched among them. These electric vortices are argued to be characterized by the center Zsub(N) of magnetic gauge group SU(N). (Auth.)
