Flavor symmetry of 5d SCFTs. Part II. Applications

In Part I of this series of papers, we described a general method for determining the flavor symmetry of any 5d SCFT which can be constructed by integrating out BPS particles from some 6d SCFT compactified on a circle. In this part, we apply the method to explicitly determine the flavor symmetry of those 5d SCFTs which reduce, upon a mass deformation, to some 5dN = 1 gauge theory carrying a simple gauge algebra. In these cases, the flavor symmetry of the 5d gauge theory is often enhanced at the conformal point. We use our method to determine this enhancement.

Automated summary

In this series of papers, a general method for determining the flavor symmetry of 5d SCFTs has been described and applied to explicitly determine the flavor symmetry of those 5d SCFTs. When these 5d SCFTs reduce to 5dN = 1 gauge theories upon a mass deformation, their flavor symmetry is often enhanced at the conformal point.
