Deconfinement at the Argyres–Douglas point in SU(2) gauge theory with broken N=2 supersymmetry

We consider chiral condensates in SU(2) gauge theory with broken N=2 supersymmetry. The matter sector contains an adjoint multiplet and one fundamental flavor. Matter and gaugino condensates are determined by integrating out the adjoint field. The only nonperturbative input is the Affleck–Dine–Seiberg (ADS) superpotential generated by one instanton plus the Konishi anomaly. These results are consistent with those obtained by the `integrating inʹ procedure, including a reproduction of the Seiberg–Witten curve from the ADS superpotential. We then calculate monopole, dyon, and charge condensates using the Seiberg–Witten approach. We show that the monopole and charge condensates vanish at the Argyres–Douglas point where the monopole and charge vacua collide. We interpret this phenomenon as a deconfinement of electric and magnetic charges at the Argyres–Douglas point.
