### Deconfining class S theories

Class S theories are a broad and interesting class of N=2 superconformal field theories arising from wrapping the six dimensional (2,0) theory on Riemann surfaces. Most of these theories have no known Lagrangian description. I will present a method (based on brane engineering) that allows to systematically construct N=1 Lagrangians flowing to some of these N=2 theories. As an illustration of the method, I will construct a Lagrangian description for the simplest non- trivial class-S theory, the $T_3$ theory with global symmetry $E_6$, and for some related examples.
