Living on the walls of Super-QCD

Super-QCD, the supersymmetric version of ordinary QCD, admits isolated vacua and dynamical domain walls between them. I will present a class of three-dimensional Chern-Simons theories to describe the effective dynamics on these walls. Our proposal passes several non-trivial checks, which I will discuss in detail. The domain wall dynamics is very rich and enjoys interesting phenomena, as for example a second order phase transition where multiple vacua coalesce into a single one and where supersymmetry gets enhanced, in some cases. Our proposal includes and extends previous results in the literature, solving also some old puzzles, and provides a complete picture of Super-QCD domain walls.
