Aspects of (SUSY) CFTs and RG flows
Abstract:
The traditional approach to quantum field theory starts with free fields and adds interactions. This approach misses many interesting, and potentially useful, quantum field theories. A broader approach is to start with conformal field theories, and consider their deformations. Supersymmetry provides a helpful handle. We will discuss superconformal field theories, their multiplets of operators, and unitary constraints on deformations, in diverse space-time dimensions.
