Course Description
Effective field theory is a fundamental framework to describe physical systems with quantum field theory. Part I of this course covers common tools used in effective theories: identifying degrees of freedom and symmetries; power counting expansions (dimensional and otherwise); field redefinitions; bottom-up and top-down effective theories; fine-tuned effective theories; matching and Wilson coefficients; reparameterization invariance; and advanced renormalization group techniques. Main examples are taken from particle and nuclear physics. Part II of this course is an in depth study of the Soft-Collinear Effective Theory (SCET), an effective theory for hard interactions in collider physics.
