High Energy Theory Seminar
We study the Higgs branch of class-S theories with twist lines, by studying their 3d reduction and corresponding mirror dual theories (or magnetic quivers).
We find many of them having the entire 'Higgs branch' fibered over an unbroken Coulomb branch direction. By this, we point out the difference between the Higgs and the Hall-Littlewood sectors, which have long been believed to be identical for genus 0 theories.
The talk is in 469 Lauritsen.
