Effective Field Theory and the Emergence of New Dynamics
Abstract: I describe applications of Effective Field Theory (EFT) to a broad range of scenarios where novel physics has been observed but the details remain poorly constrained. I discuss how EFT allows one to simplify and organize existing models, as well as providing an efficient framework for envisioning and parameterizing general possibilities in a more model-independent manner. Applications covered will be inflation in the early universe, experiments looking for direct detection of dark matter, and novel phases in superconducting metals.
