  • Friday 9:45 - 11:15, online live lecture discussing topics of the previous week

General Information

  • The lecture and the tutorials will be given in English.
  • The problem sets will be handed in by the students, graded/corrected by the tutor and discussed in the tutorials the following week.
  • Admission to the final exam requires 66% of the points on the problem sets.
  • Please register for the exercise groups online. To do so, you need the Lecture Key given in the first lecture.
  • If you assign a password at the registration, you can request your current scores here.


There will be an oral examination at the end of the course. Details will be given in the lecture.



The goal is to gain a thorough understanding of relativistic quantum field theory, the concepts of Feynman diagrams, renormalisation for quantum electrodynamics, and to extend this knowledge to non-abelian gauge theories. In particular:

  • Relativistic quantum mechanics and Dirac equation
  • Path integral formalism
  • Quantisation - Free fields
  • Interacting fields and Feynman diagrams
  • Elementary processes and first corrections
  • Renormalisation
  • Non-abelian gauge fields


These notes follow mostly the exposition of Peskin & Schroeder. They are not an extension of the material covered in the lectures but the script that I use to prepare them. Please have a look at Peskin & Schroeder and the given references for more comprehensive coverage; the corresponding pages are noted in the headers (→ P&S • pp. xx-yy).
