Because there is no projector in the room, the quality will be poor.
If mandated by the University or the Hessen government, we will switch to an online format using this zoom meeting room.

Lecturer

Prof. Dr. Guy Moore

Assistant

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

Homeworks and Solutions

All homeworks will appear here at least 1 week before they are due.
