The Phase Structure of Supersymmetric Sp(2Nc) Gauge Theories with an Adjoint
Abstract
We study the phase structure of N = 1 supersymmetric Sp(2Nc) gauge theories with 2Nf fundamentals, an adjoint, and vanishing superpotential. Using a-maximization, we derive analytic expressions for the values of Nf below which the first several gauge-invariant operators in the chiral ring violate the unitarity bound and become free fields. In doing so we are able to explicitly check previous conjectures about the behavior of this theory made by Luty, Schmaltz, and Terning. We then compare this to an analysis of the first two 'deconfined' dual descriptions based on the gauge groups Sp(2Nf+2) x SO(2Nc+5) and Sp(2Nf+2) x SO(4Nf+4) x Sp(2Nc+2), finding precise agreement. In particular, we find no evidence for non-obvious accidental symmetries or the appearance of a mixed phase in which one of the dual gauge groups becomes free.
