A note on dualities of F(4) type 3d N = 5 SCFTs

TL;DR

This paper proposes a new duality between two 3d N=5 superconformal field theories, one of ABJ type and one based on the exceptional superalgebra F(4), supported by matching superconformal indices.

Contribution

It introduces a novel duality between specific 3d N=5 SCFTs involving F(4), expanding understanding of strongly coupled theories and aiding classification efforts.

Findings

Matching superconformal indices support the duality

Duality links ABJ type and F(4)-based theories

Enhances classification of 3d N=5 SCFTs

Abstract

We suggest a new duality between a pair of 3d N = 5 SCFTs, one of ABJ type and one based on the exceptional superalgebra F (4). Our main evidence for the proposed duality is the matching of the superconformal index. In addition to the intrinsic interest in dualities between strongly coupled field theories, the result can also be useful in the classification of 3d N = 5 SCFTs.
