SS 18

 

Lecturer
Begin of lecture

Wednesday, 11 April 2018

Time and Date
  • Wednesday, 9:45 - 11:15 a.m., Seminar Room 5.331, Pfaffenwaldring 57
  • Friday, 2:00 - 3:30 p.m., Seminar Room 5.331, Pfaffenwaldring 57
General Information
  • The lecture and the tutorials will be given in English.
  • There are two types of exercises: "Written" exercises are handed in in class and graded/corrected by the tutor. "Oral" exercises are discussed in the tutorials and presented by students on the blackboard.
  • Admission to the final exam requires 80% of the written scores, 66% of the oral scores, and presenting a problem on the blackboard twice.
  • The registration for the exercise groups is now open. In order to register, 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.
Examination

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

Literature
Topics

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
