The Course Syllabus is available here.

The course will follow the textbook Quantum Field Theory by Mark Srednicki. My goal is to cover chapters 1-14, 22, 33-48, 54-59, and then as much of the skipped-over chapters as we can.

Late homeworks will be accepted by pre-arrangement, with good reason, or within 2 days at a 25% reduction of the grade. I cannot accept homeworks after the solutions are posted.

The course grade will be based **entirely** on the homeworks. You can work
with each other and ask each other questions; you can also ask me
questions, and I encourage you to corner me, especially as a group if
you find you have a question you are all confused about.

For those of you who would like additional or alternative textbooks, I will make a few recommendations. Shop around for prices, I just gave links to show you exactly what book I meant.

Peskin and Schroder is a standard in the field. The metric choice is different, so is the emphasis. It's good to have especially if you intend to do phenomenology or QCD.

Ryder's book is a slightly less advanced text which many people like but which I don't know well myself.

Zinn-Justin is the bible of Quantum Field Theory but is much more formal than I intend to be in our class. Buy it if you intend to take Quantum Field Theory really seriously but not if you are on a tight budget.

Steven Weinberg's book is a place to go if you want everything spelled out in complete detail, but not if you want clear expository explanations. It is a reference, not really a textbook.
