I am all on my own!!
Course book
Quantum Field Theory by Peskin and Schroder
And/Or Srednicki (which you can download free from that page!)
NOTE that these two books use different conventions!
Therefore I am giving you a few helpful extra readings, which I will put here:
a PDF document reviewing group theory and representation theory
a PDF document reviewing the Lorentz group and its representations (Dirac algebra)
a PDF document summarizing how to jump back and forth between metric (and other) conventions
Topics
- Brief review of Quantum Field Theory I
- Systematics of Renormalization
- Renormalization Group
- Nonabelian Gauge Theory
- Quantum Chromodynamics and its phenomenology
- (Time permitting) Anomalies; Higgs Mechanism; Other advanced topics
