**Introduction to Effective Field Theory**

by C. P. Burgess

**Publisher**: arXiv 2007**Number of pages**: 55

**Description**:

This review summarizes Effective Field Theory techniques, which are the modern theoretical tools for exploiting the existence of hierarchies of scale in a physical problem. The general theoretical framework is described, and explicitly evaluated for a simple model. Power-counting results are illustrated for a few cases of practical interest, and several applications to Quantum Electrodynamics are described.
