Content, Learning Outcome and Preconditions
Content
- Functional (path integral) quantisation of bosonic and fermionic fields
- Green functions
- Perturbation expansion, Feynman diagrams
- Particle states, LSZ reduction and cross sections
- Gauge invariance and quantisation of non-abelian gauge theories
- Ward-Takahashi identities
- Loop calculations and UV regularisation
- Dimensional regularisation
- Renormalisation, in particular of gauge theories
- Next-to-leading order effects in gauge theories (e.g. anomalous
- magnetic moment, infrared divergences and soft bremsstrahlung)
- Effective field theory
- Renormalisation group, running couplings and masses
Learning Outcome
After successful completion of the module the student will be prepared
- to compute Green functions in perturbation theory, including loop corrections, and apply these to calculations of high-energy reactions;
- to quantise non-Abelian gauge theory and to calculate tree- and loop processes;
- to understand the concepts of regularisation and renormalisation and to apply these in calculations;
- to improve perturbative calculations using the renormalisation group;
- to construct effective quantum field theories.

Module Exam
Description of exams and course work
In a written exam the learning outcome is tested using comprehension questions and sample problems.
In accordance with §12 (8) APSO the exam can be done as a oral examination. In this case the time duration is 30 minutes.
Exam Repetition
The exam may be repeated at the end of the semester.
