Flips, dualities and symmetry enhancements

We present various 4d N = 1 theories enjoying IR global symmetry enhancement. The models we consider have the USp(2N) gauge group, 8 fundamental, one antisymmetric chirals and various numbers of gauge singlets. By suitably turning on superpotential deformations involving the singlets which break part of the UV symmetry we flow to SCFTs with E-6, SO(10), SO(9), SO(8) and F-4 IR global symmetry. We explain these patterns of symmetry enhancement following two arguments due to Razamat, Sela and Zafrir. The first one involves the study of the relations satisfied by marginal operators, while the second one relies on the existence of self-duality frames.

Automated summary

In this study, various 4d N = 1 theories with IR global symmetry enhancement are presented. These models have USp(2N) gauge group, 8 fundamental particles, one antisymmetric chiral, and varying numbers of gauge singlets. By using superpotential deformations involving the singlets, the UV symmetry is broken leading to SCFTs with E-6, SO(10), SO(9), SO(8) and F-4 IR global symmetry. The patterns of symmetry enhancement are explained using two arguments by Razamat, Sela and Zafrir, one involving the study of relations satisfied by marginal operators and the other relying on the existence of self-duality frames.
