Symmetry enhancement in 4d Spin(n) gauge theories and compactification from 6d

Abstract

We consider a known sequence of dualities involving $4d$ $\mathcal{N}=1$ theories with $Spin(n)$ gauge groups and use it to construct a new sequence of models exhibiting IR symmetry enhancement. Then, motivated by the observed pattern of IR symmetries we conjecture six-dimensional theories the compactification of which on a Riemann surface yields the $4d$ sequence of models along with their symmetry enhancements, and put them to several consistency checks.
