Physics 215a, Quantum Field Theory 2012

Professor: Ken Intriligator, Mayer Hall 5234. Office hours Tues 4-5pm.

In class final exam, Thursday Dec 13, 11:30-2:30 pm. Bring one (standard sized) page of formulae, front and back. No formulae sheet will be given on the exam.

Suggested study exercises for the final: questions 1 and 2 here.

Text: The lectures will largely follow these free, online notes:

  • Sidney Coleman's lectures. Classic videos can be found here

  • Mike Luke's lecture notes,

  • David Tong's lecture notes.

    Some HW exercises will be assigned from Peskin and Schroeder, which is also highly recommended.

    Office hours: Tuesdays, 4-5pm.

    Highly recommended book for advanced QFT topics Coleman's Aspects of Symmetry

    Course Times :MW 12:30-1:50pm, MHA 2623. Final: Thursday 12/13/12, 11:30-2:30

    Homework: It is essential to do your exercises. Many of the assigned problems have solutions that can be found online -- try to resist that, it's cheating both yourself, and it is technically, officially cheating. Working together in groups is fine, and encouraged, as long as everyone is working.

    Homework: Homework: 50%, final 50%.
