- Descrição
- In this talk we review some generalizations of 't Hooft and Mandelstam ideas on confinement for theories with non-Abelian unbroken gauge groups. In order to do that, we consider N=2 super Yang-Mills with one flavor and a mass breaking term. One of the spontaneous symmetry breaking is accomplished by a scalar that can be in particular in the representation of the diquark condensate. We analyze the phases of the theory. In the superconducting phase, we show the existence of BPS $Z_k$-strings and calculate exactly their string tension in a straightforward way. We also find that magnetic fluxes of the monopole and $Z_k$-strings are proportional to one another allowing for monopole confinement in a phase transition. We futher show that some of the resulting confining theories can be obtained by adding a deformation term to $N=2$ or $N=4$ superconformal theories.
