Almost conformal vacua and confinement Original Research Article

Dynamics of confining vacua which appear as deformed superconformal theory with a non-Abelian gauge symmetry, is studied by taking a concrete example of the sextet vacua of N=2, SU(3) gauge theory with nf=4, with equal quark masses. We show that the low-energy “matter” degrees of freedom of this theory consist of four magnetic monopole doublets of the low-energy effective SU(2) gauge group, one dyon doublet, and one electric doublet. We find a mechanism of cancellation of the beta function, which naturally but nontrivially generalizes that of Argyres–Douglas. Study of our SCFT theory as a limit of six colliding N=1 vacua, suggests that the confinement in the present theory occurs in an essentially different manner from those vacua with dynamical abelianization, and involves strongly interacting non-Abelian magnetic monopoles.
