Oppositely Charged

Flux tube solutions are found in the square root gauge theory. Purely magnetic solutions exist which do not contain radiation. It is found that no electric monopole solution exists, which is a sign of electric charge confinement, but magnetic monopole solutions exist and therefore there is no confinement of magnetic charge. There are also solutions which have both electric and magnetic components and represent flux tubes where in addition some radiation process, caused for example by some annihilation in the center of the tube takes place. Finally, there are solutions with both electric and magnetic field which do not represent radiation but rather electric flux tubes, which are good candidates for describing confinement of oppositely charged sources. Demanding angular momentum quantization leads to the quantization of the length of these tubes.

Infrared Divergences

We show that in the presence of condensation of a gauge field there is confinement of chromodynamic charges. Between these confined charges an electric flux tube is generated. In particular we have considered the classical solutions for an SU (2) Yang-Mills theory in the presence of such a condensate. This treatment has been motivated by the cancellation of infrared divergences in 2+1 dimensions.

We investigate the effect of external field boundary conditions of a background chromomagnetic field on the instability (discovered by Nielsen and Olesen) for the vacuum of a non-Abelian field theory. We find that the vacuum is neither stabilized by a one-dimensional nor a two-dimensional cutoff of this magnetic field. However, the vacuum in the presence of flux tubes whose length is restricted to be under a critical value, L0, is stable. Therefore, there is a tendency for flux tubes of lengths greater than L0 to spontaneously fragment into segments each of which is smaller than L0. This corresponds to a dual picture which allows stable electric flux tubes.
