Duff Neill (Los Alamos National Laboratory)--Introduction to Effective Field Theory

Duff Neill (Los Alamos National Laboratory) gives us an Introduction to Effective Field Theory.
Abstract:
Effective Field Theory (EFT) is a powerful way to think about physical systems, by being strict on relying on the degrees of freedom relevant to the problem at hand. Soft-collinear Effective Theory is perhaps one of the most well-developed and sophisticated applications of EFT techniques, designed to deal with high-energy scattering processes in gauge theories, but in this first lecture, to learn how to think according to the EFT paradigm, we will deal with a simpler physical system: jelly. I will illustrate the three ingredients to make an EFT: the degrees of freedom, the symmetries, and the power counting. Using these tools, we will derive some simple consequences for the theory of jelly, but more importantly, we will learn how to think in an EFT way.

Bio:
Duff Neill received his Ph.D. from Carnegie Mellon University in 2012. Duff was then a Pappalardo Postdoctoral Fellow at MIT until 2016 working on the physics of high-energy jets at the LHC. Duff then went to Los Alamos National Laboratory (LANL) as a Feynman Fellow, working in the T2 group in Theory Division. Since 2020, Duff has been a permanent Staff member at LANL.
