Title: Bounds on 4D Conformal and Superconformal Field Theories
Host: Luty
Room: 432
Near-conformal dynamics may play an important role in beyond the standard model physics, but many scenarios rely crucially on assumptions about the behavior of strongly-coupled field theories that are difficult to check. I will present recent work aimed at getting a better understanding the range of behavior that is possible in 4D conformal field theories. In particular, I will discuss how unitarity combined with crossing symmetry of four-point functions leads to general bounds on operator dimensions, central charges, and OPE coefficients in both supersymmetric and non-supersymmetric CFTs.
