Description
I will discuss a class of CFTs obtained by Higgsing the (2,0) ADE theory by a pair of nilpotent elements in the ADE group. In the A and D case, the nilpotent elements are labeled by Young diagrams, and the holographic dual is known explicitly in IIA supergravity. In the E case and in some D cases, only an F-theory description is available, using sevenbranes with a pole for the Higgs field. The effect of these "T-branes" is conjectural, but it passes several numerical tests.
Compactifying to four dimensions should produce new "massive class S" theories; for some easy cases, the AdS5 duals are now emerging, even in presence of punctures.
