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.
