“Aspects of (susy) CFTs and RG flows”
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.
