Physics 331 -- Quantum Field Theory
Physics 331 is the second course of a 3-quarter sequence on Quantum Field
Theory, the theory that provides at the same time the relativistic
generalization of quantum theory and the basic formalism for theories of
elementary particles. Michael Peskin gave this sequence of courses
at Stanford
during the 04-05 and 05-06 academic years.
This web site provides an archive for the materials that he prepared.
The three quarters of Physics 330-331-332 cover:
- Physics 330:
Free scalar and spinor fields,
Feynman diagrams, basic processes of Quantum Electrodynamics, radiative
corrections
- Physics 331: Functional integral formulation of quantum field theory,
Yang-Mills theory, Quantum Chromodynamics, spontaneously broken
symmetry, Higgs mechanism, Glashow-Salam-Weinberg model of weak
interactions
- Physics 332:
Theory of renormalization, renormalization of models with
spontaneously broken symmetry, renormalization group,
asymptotic freedom, operator product expansions,
perturbation theory anomalies.
The textbook for the course was An Introduction to Quantum Field Theory,
by Peskin and Schroeder. Other useful references are listed in the
general course information.

Final exams (and the solutions) from 2005 and 2006:
In contrast to my usual practice, I did not hand out lecture
notes for Physics 331. This is because the textbook is remarkably
well-written (!), so I followed it closely. For topics that go
beyond the textbook, I post lecture notes below.
The outline below indicates
the approximate content of the lectures in 2006:
- Jan. 11 : Non-Abelian gauge fields
- Jan. 18 : A little about Lie Algebras
- Jan. 23 : The Feynman path integral
- Jan. 25 : Path-integral quantization of fields
- Jan. 30 : Path-integral quantization of gauge fields and fermions
- Feb. 1 : Perturbation theory for non-Abelian gauge fields
- Feb. 6 : Asymptotic freedom
- Feb. 8 : QCD, deep inelastic scattering
- Feb. 13 : Quark-gluon scattering processes
- Feb. 15 : Altarelli-Parisi evolution
- Feb. 22 : Spontaneous symmetry breaking
- Feb. 27 : The Higgs mechanism
- Mar. 1 : The Glashow-Salam-Weiberg model of weak interactions
- Mar. 6 : Symmetries of the "Standard Model" of particle physics
- Mar. 8 : R-xi gauges and Goldstone boson equivalence
- Mar. 13 : Grand
unification
- Mar. 15 : Magnetic
monopoles in unified gauge theories
