Lectures on Effective Field Theory

Abstract

In these 4 lectures, I give a brief introduction to the principles of effective field theory and discuss their application via 3 examples: (i) the Standard Model as an effective theory; (ii) non-linear sigma models and the composite Higgs; (iii) the quantum field theory of fluids.
