Quantum Field Theory

This is an introductory course on Quantum Field Theory where quantization is described in terms of path integrals. Although most of the subject is worked out in detail, I assume that students already know the properties of relativistic equations for particles of spin 0, 1/2 and 1. The goal is understanding the properties of Quantum Electrodynamics beyond the tree level.

How to prepare the examination

How can you judge that you have reached a good level of understanding and that you are "ready to go"? I tried to figure out a number of questions that you should be able to answer. If you have doubts on any of these points, please ask me to clarify them during the class. Do not esitate. To begin with, have a look to what you should know about the chapter Beyond the tree level approximation. If you have been able to answer to all questions, you can move to General renormalization theory . Are you reasonably happy with your answers to the previous questions? If this is the case, you are ready for the examination.
