Non-Abelian vortices in image gauge theory Original Research Article

We consider the image supersymmetric image gauge theory and demonstrate that the image vortices in this theory acquire orientational zero modes, associated with the rotation of magnetic flux inside image group, and turn into the non-Abelian strings, when the masses of all chiral fields become equal. These non-Abelian strings are not BPS-saturated. We study the effective theory on the string world sheet and show that it is given by two-dimensional non-supersymmetric image sigma model. The confined ʹt Hooft–Polyakov monopole is seen as a junction of the image-string and anti-string, and as a kink in the effective world sheet sigma model. We calculate its mass and show that besides the four-dimensional confinement of monopoles, they are also confined in the two-dimensional theory: the monopoles stick to anti-monopoles to form the meson-like configurations on the strings they are attached to.
