• Passing criteria and grading
• To pass the course you need to actively participate in the exercises according to the following rules:
  • You do not have to hand in written solutions to the exercises, but you have to be able to present the solutions on the blackboard.
  • At the beginning of each exercise session you check which problem you are prepared to present. The presenter will be chosen at random.
  • Over the course of the semester you have to check at least 50% of all problems.
• There will be an exam at the end of the semester. The result of this exam determines your final grade.


• Literature
• Most of the lecture will follow the textbook "An Introduction to Quantum Field Theory" by Peskin & Schroeder. Older editions of this book contain a number of typos, see this errata page. For a better understanding of the subject it is a good idea to also consult other textbooks, see the following list and the references in Peskin & Schroeder.
• Mandl & Shaw: Quantum Field Theory
• Itzykson & Zuber: Quantum Field Theory
• Weinberg: The Quantum Theory of Fields I and II
• Ryder: Quantum Field Theory
• Siegel: Fields
• Zee: Quantum Field Theory in a Nutshell
• Bjorken & Drell: Relativistic Quantum Fields
• Aitchison & Hey: Gauge Theories in Particle Physics
• Halzen & Martin: Quarks and Leptons
• Gradshteyn and Ryzhik: Table of Integrals, Series, and Products (mathematical reference book for integrals etc.)
