Notes on $\mathcal{N}=1$ QCD${}_3$ with baryon superpotential

Abstract

We study the infrared phases of $\mathcal{N}=1$ QCD${}_3$ with gauge group $SU(N_c)$ and with the superpotential containing the mass term and the baryon operator. We restrict ourselves to the cases, when the number of flavors is equal to the number of colours, such that baryon operator is neutral under the global $SU(N_F)$. We also focus on the cases with two, three and four colours, such that the theory is perturbatively renormalizable. On the $SU(2)$ phase diagram we find two distinct CFTs with $\mathcal{N}=2$ supersymmetry, already known from the phase diagram of $SU(2)$ theory with one flavor. As for the $SU(3)$ phase diagram, consistency arguments lead us to conjecture that also there supersymmetry enhancement to $\mathcal{N}=2$ must occur. Finally, similar arguments lead us to conclude that also for the $SU(4)$ case we should observe supersymmetry enhancement at the fixed point. Yet, we find that this conclusion would be in contradiction with the renormalization group flow analysis. We relate this inconsistency between the two kinds of arguments to the fact that the theory is not UV complete.
