Higher spin theories, holography and Chern-Simons vector models

I will first briefly overview recent progress in testing the holographic duality between 3d vector models and higher spin gravity theories in four-dimensional Anti-de Sitter space. I will then discuss some new results on the CFT obtained by coupling 3d vector models to a Chern-Simons gauge field. In particular, I will show that such theory has a higher spin symmetry in the infinite N limit, and propose that it should be holographically dual to a parity breaking higher spin gravity theory.
